Arizona — Tax & Mortgage Foreclosure

Legal information, not legal advice. Verify against the cited primary sources before acting. Last verified: 2026-06-01.

Arizona is a tax-lien-certificate state (not a tax-deed state for the delinquent-tax sale itself). Counties auction a certificate of purchase (CP) on delinquent parcels; the buyer earns statutory interest and, after a 3-year hold, may bring a judicial action in Superior Court to foreclose the owner’s right to redeem. Mortgage foreclosure is overwhelmingly non-judicial via deed-of-trust trustee’s sales (Title 33, Ch. 6.1), with a robust anti-deficiency shield. Following tyler-v-hennepin-county (2023), Arizona’s legislature bolted an excess-proceeds sale mechanism onto its tax-lien foreclosure statute (A.R.S. § 42-18204, as amended) so a former owner can capture surplus equity rather than forfeit the whole parcel to the CP holder.

0. Identity & Classification

  • Recording unit: county (count: 15)
  • Tax sale type: tax lien certificate (certificate of purchase); a treasurer’s deed issues later only if the lien is foreclosed and no excess-proceeds sale is ordered.
  • Tax foreclosure process: judicial — action to foreclose the right to redeem in Superior Court (A.R.S. § 42-18201). [Source: azleg.gov §42-18201]
  • Mortgage foreclosure process: both, but predominantly non-judicial (deed-of-trust trustee’s sale, A.R.S. § 33-807); judicial mortgage foreclosure available under Title 33, Ch. 6.
  • Selling authority: county treasurer (tax lien sale & tax foreclosure deed); trustee (deed-of-trust sale); sheriff (judicial-foreclosure / execution sale).
  • Statutory home: Title 42, Ch. 18 (Property Tax — Collection / Tax Liens) — https://www.azleg.gov/ars/42/18201.htm ; Title 33, Ch. 6.1 (Deeds of Trust) — https://www.azleg.gov/ars/33/00807.htm
  • Tyler v. Hennepin compliance: reformed_post_Tyler — A.R.S. § 42-18204 now lets a property owner facing foreclosure of redemption request an excess-proceeds sale; the court must order it where the price is likely to exceed the tax debt/costs by more than $2,500, and the judgment “does not extinguish the property owner’s interest in the excess proceeds.” [Source: azleg.gov §42-18204] Pre-amendment, the CP holder took the whole parcel free of any surplus obligation — the practice an Arizona State Law Journal analysis flagged as constitutionally vulnerable after Tyler. [Source: arizonastatelawjournal.org]

1. Tax Sale Mechanics

  • What is sold: lien certificate (certificate of purchase / “CP”).
  • Bidding method: bid-down interest — the lien is struck to the bidder willing to accept the lowest interest rate, starting at the 16% statutory ceiling and bid downward (0–16%). Liens not sold are “struck to the state” and bear 16%. [Source: azleg.gov §42-18053; Pima/Pinal treasurer booklets]
  • Interest / penalty: 16% per year, simple, from the date of delinquency until paid (A.R.S. § 42-18053(A)); the CP earns interest at the bid rate (≤16%) from the first day of the month following purchase. Statutory max = 16%. [Source: azleg.gov §42-18053]
  • Minimum bid composition: delinquent taxes + accrued interest at 16% + penalties + statutory fees/costs of sale. [Source: azleg.gov §42-18053; county treasurer booklets]
  • Sale frequency: annual.
  • Typical month: February (statutory tax-lien sale season).
  • Venue: both, predominantly online in larger counties.
  • Platform vendors: county-contracted online auction platforms (e.g., RealAuction-type systems used by Maricopa/Pima). (specific vendor per county — see needs_verification.)
  • Registration / deposit: bidder registration and a deposit are required before the online sale; terms set per-county. (exact deposit % — needs_verification.)
  • Subsequent taxes (“subs”): the CP holder may pay subsequent years’ taxes and endorse them on the certificate; subs earn interest at the same rate stated on the CP and are added to the redemption amount. [Source: azleg.gov §42-18121 / redemption-amount statutes; county booklets]

2. Right of Redemption → see right-of-redemption

  • Pre-sale right: the owner may pay delinquent taxes any time before the lien is sold (i.e., the lien sale itself is avoidable by paying). [Source: Title 42 Ch. 18 framework]
  • Post-sale period: 3 years from the date of the tax-lien sale; redemption remains available even after 3 years until a treasurer’s deed is delivered to the CP holder or the right is foreclosed by judgment (A.R.S. § 42-18152). Foreclosure of redemption may be commenced only after the 3-year mark and must be filed within 10 years of the month the lien was acquired (A.R.S. § 42-18201). [Source: azleg.gov §42-18152, §42-18201]
  • Who may redeem: the owner; the owner’s agent, assignee, or attorney; any person with a legal or equitable interest in the property (including a holder of a CP of a different date); a person paying as a charitable gift on the owner’s behalf; a partial-interest owner may redeem proportionally (A.R.S. § 42-18151). [Source: azleg.gov §42-18151]
  • Amount formula: the price the lien sold for + interest at the CP rate + all subsequent taxes the CP holder paid + interest on those subs at the CP rate
    • statutory fees/costs. [Source: azleg.gov §42-18053 + redemption-amount statutes]
  • Premium to certificate holder: none beyond statutory interest (the “premium” is the bid-down interest the CP holder earns; max 16%).
  • Procedure: redeem through the county treasurer, who issues a certificate of redemption; if foreclosure is pending, redemption may occur any time before judgment is entered (and the redeeming party served personally or by publication is liable for the plaintiff’s costs and reasonable attorney fees). [Source: azleg.gov §42-18204 (redemption before judgment)]
  • Extinguishment: the right to redeem is cut off by the judgment foreclosing the right to redeem (A.R.S. § 42-18204) and delivery of a treasurer’s deed (or, where an excess-proceeds sale is ordered, by that sale).
  • Special tolling: general civil disability/tolling principles may apply (minors, incompetents); SCRA protections apply to servicemembers. (state-specific tolling for tax-lien redemption — needs_verification.)

3. Surplus / Excess Proceeds → see surplus-funds, third-party-recovery-rules

(A) Tax-lien foreclosure surplus (Title 42). Historically, foreclosure of the right to redeem vested the entire parcel in the CP holder, generating no surplus for the former owner. Post-Tyler, A.R.S. § 42-18204 now provides:

  • Belongs to: former property owner (priority_waterfall for lienholders first, then owner).
  • Mechanism: a property owner whose right to redeem is being foreclosed may request the court to order an excess-proceeds sale. The court shall find such a sale reasonable if the sale price is likely to exceed by more than $2,500 the total of the CP holder’s costs, the lien purchase amount + 16% interest, statutory fees + 16% interest, and other reasonable court-determined fees. [Source: azleg.gov §42-18204]
  • Opening bid: set at the total outstanding costs/fees/interest related to the property. The sale must occur within ~60 days of judgment with recording, posting, publication, certified-mail, and MLS-listing notice; bidders post a 10%/$2,500 deposit. [Source: azleg.gov SB1431 fact sheet]
  • Claim waterfall (per the SB1431 reform / § 42-18204 & Art. 6):
    1. qualified-entity / facilitation costs;
    2. CP holder: filing costs, lien purchase + 16% interest, statutory fees + 16% interest;
    3. other non-state property-tax & encumbrance holders per the title report;
    4. former owner receives the remaining proceeds. [Source: azleg.gov SB1431 fact sheet; §42-18204]
  • Key statutory text: the foreclosure judgment “does not extinguish the property owner’s interest in the excess proceeds from the sale of the property.” [Source: azleg.gov §42-18204]

(B) Trustee’s-sale / mortgage-foreclosure surplus (Title 33). Under A.R.S. § 33-812 the trustee distributes sale proceeds in this order:

  1. costs/expenses of the sale incl. trustee’s fees & reasonable attorney fees;
  2. the secured obligation owed the beneficiary;
  3. other obligations secured by the deed of trust actually paid by the beneficiary;
  4. HOA/condo subordinate liens on written claim;
  5. junior lienholders/encumbrancers in order of priority, then the trustor / current record owner. [Source: azleg.gov §33-812]
  • Filing venue: if claimants conflict, the trustee may deposit the surplus with the county treasurer and file a civil action (naming the treasurer) in Superior Court to determine entitlement. [Source: azleg.gov §33-812]
  • Claim deadline: a person claiming the proceeds must file a response within 45 days of the latest mailing of the application; if a non-party appears to have a superior right, the court shall not order distribution until 180 days after the complaint was filed. [Source: azleg.gov §33-812]
  • Escheat: deposited funds presumed abandoned after 2 years with no pending application transfer to the county general fund (if ≤ $50) or to the Arizona Department of Revenue unclaimed-property (if >$50). [Source: azleg.gov §33-812]
  • Documentation required: application/claim with proof of identity and of the claimant’s interest (deed, lien, assignment, title report). [Source: azleg.gov §33-812 process]
  • Third-party recovery (excess-proceeds finders / recovery agents):
    • fee_cap_pct: (no Arizona statute capping excess-proceeds-finder fees located — needs_verification)
    • licensing_required: (unverified — needs_verification)
    • assignment_of_claim_allowed: yes — Arizona case law recognizes assignees pursuing surplus (see tortosa-homeowners-association-v-garcia-2022, where an assignee of a senior lien (Maricopoly/U.S. Bank) litigated the surplus). [Source: descrybe.ai / Sammartino summary of Tortosa]
    • cooling_off_period / contract_disclosure_rules / prohibited_practices: (no specific Arizona excess-proceeds-finder consumer-protection statute located — needs_verification)
    • citation: A.R.S. § 33-812 (claim process); (finder-specific regulation — needs_verification)
  • Notice to former owner required? Yes — for tax excess-proceeds sales, certified-mail + recording/posting/publication notice (A.R.S. § 42-18204 / SB1431); for trustee-sale surplus, the application-and-response procedure of A.R.S. § 33-812 with mailed notice to interested parties. [Source: azleg.gov §42-18204, §33-812]

▸ For Investors / Operators — Arizona is a tax-lien-certificate (certificate of purchase) state — the lien is struck to the bidder accepting the lowest interest rate (bid down from 16%). Historically foreclosure of the right to redeem vested the whole parcel in the CP holder with no surplus; post-Tyler, A.R.S. § 42-18204 lets the owner request an excess-proceeds sale so the residual reaches the former owner. Before committing capital, weigh the redemption risk (§2/2b — the 3-year redemption that runs until a treasurer’s deed is delivered, and CP/assignment mechanics), the path to marketable/ insurable title (§5b — a § 12-1103 quiet title in Superior Court; the § 42-18205 deed issues ministerially after the foreclosure judgment but is not immediately insurable), and which liens survive (§7b — Title 48/§ 9-276 assessment liens survive under § 42-18115, and the IRS § 7425 120-day redemption applies; Arizona HOA liens are not super-priority).

▸ For Former Owners — When an Arizona tax-lien foreclosure proceeds, A.R.S. § 42-18204 lets you request the court to order an excess-proceeds sale, and the court shall find it reasonable where the price is likely to exceed the CP holder’s costs by more than $2,500; the judgment “does not extinguish the property owner’s interest in the excess proceeds.” For a trustee’s-sale surplus, the § 33-812 application-and-response procedure applies (file a response within 45 days of the latest mailing); deposited surplus is presumed abandoned after 2 years and routes to the county general fund or Arizona Department of Revenue unclaimed property.

4. Mortgage Foreclosure

  • Process: both; non-judicial trustee’s sale (A.R.S. § 33-807) is the norm.
  • Timeline: trustee records a notice of trustee’s sale (A.R.S. § 33-808); the power of sale may not be exercised before the 91st day after recording the notice (A.R.S. § 33-807 / § 33-808) — i.e., ~90-day minimum. [Source: azleg.gov §33-807, §33-808]
  • Reinstatement right: yes — the trustor may cure the default (pay the arrears, trustee’s fees, and statutory costs, not the full accelerated balance) up to 5:00 p.m. on the last business day before the sale (A.R.S. § 33-813). [Source: azleg.gov §33-813]
  • Redemption after sale: none after a trustee’s sale — the sale is final, no statutory post-sale redemption. (Statutory post-sale redemption exists only after a judicial foreclosure/execution sale under Title 12.) [Source: trustee-sale statutory scheme, Title 33 Ch. 6.1]
  • Deficiency judgment: allowed within 90 days of the trustee’s sale (A.R.S. § 33-814(A)), measured as debt minus the greater of fair market value or the sale price (fair-value offset). Anti-deficiency bar: for residential property of 2.5 acres or less used as a single one- or two-family dwelling sold by trustee’s sale, no deficiency action lies (A.R.S. § 33-814(G)); a parallel purchase-money judicial bar exists at A.R.S. § 33-729. The fair-value protection cannot be waived (Arizona Supreme Court). [Source: azleg.gov §33-814]
  • One-action rule: Arizona has anti-deficiency limits but is not a strict one-action state in the California sense. (precise one-action characterization — needs_verification)
  • Surplus distribution: per A.R.S. § 33-812 (see Module 3B).
  • Sale officer: trustee (non-judicial); sheriff (judicial/execution).

5. Sale Procedure Playbooks

  • Treasurer / tax-collector tax-lien sale — ordered steps → see treasurer-sale
    1. Treasurer publishes the delinquent list (statutory publication).
    2. February online/in-person auction; bidders register & deposit.
    3. Bid-down interest from 16%; lowest-rate bidder wins the CP. Unsold liens struck to the state at 16%.
    4. CP holder may pay & endorse subsequent taxes (“subs”).
    5. Owner may redeem through the treasurer within 3 years (or until deed/ judgment).
    6. After 3 years, CP holder sends § 42-18202 notice (certified mail, 30–180 days pre-suit), then files the § 42-18201 action to foreclose.
    7. Court enters judgment foreclosing redemption (§ 42-18204) → treasurer’s deed unless the owner obtains an excess-proceeds sale order. [Source: azleg.gov §42-18053, §42-18152, §42-18201, §42-18202, §42-18204]
  • Sheriff / trustee sale — ordered steps → see sheriff-sale
    1. Default → lender/trustee records notice of trustee’s sale (§ 33-808).
    2. Mail/post/publish notice; ≥ 91 days before sale (§ 33-807/§ 33-808).
    3. Trustor may reinstate until 5 p.m. the day before sale (§ 33-813).
    4. Auction; trustee’s deed to highest bidder; no post-sale redemption.
    5. Proceeds distributed per § 33-812; surplus deposited with treasurer if contested. [Source: azleg.gov §33-807, §33-808, §33-812, §33-813]
  • Notice requirements: tax-lien foreclosure pre-suit notice by certified mail, 30–180 days before filing (§ 42-18202); trustee’s sale notice recorded
    • mailed + posted + published per § 33-808/§ 33-809. [Source: azleg.gov §42-18202, §33-808]
  • Upset bid / confirmation: none for trustee’s sales (sale is final, no judicial confirmation); tax-foreclosure judgments are entered by the court.
  • Payment terms: trustee’s-sale bidders pay per the notice terms (cash/certified funds, typically by the next business day); tax excess-proceeds-sale bidders post 10%/$2,500 deposit, balance by 5 p.m. next business day. [Source: azleg.gov SB1431 fact sheet]
  • Deed issued: treasurer’s deed (tax foreclosure, no warranty / quitclaim- quality) or trustee’s deed (mortgage), conveying the interest foreclosed; no statutory warranty of title.

6. Due Process & Notice → see due-process-notice

  • Standard: notice “reasonably calculated” to apprise the owner (mullane-v-central-hanover), with actual mailed notice to record interest-holders (mennonite-v-adams) and additional reasonable steps when mail is returned (jones-v-flowers).
  • Arizona application: the § 42-18202 pre-foreclosure notice is jurisdictional — advanced-property-tax-liens-v-othon-2021 (Ct. App.) held a court may not enter a foreclosure judgment unless the CP holder sent the required notice, and that when certified mail is returned unclaimed the holder must make a “genuine investigation” to locate the owner, not a nominal attempt. On review, the Arizona Supreme Court (2023) held that a party who never recorded its deed could not collaterally attack the underlying default foreclosure judgment in a later quiet-title action — limiting who and when the notice defect can be raised. [Source: findlaw / azfreenews Othon coverage]
  • Substantial vs. strict compliance: dupont-v-reuter (Ct. App.) held that serving the § 42-18202 notice by regular instead of certified mail was an “insubstantial failure” (relying on § 42-18101(B)) that did not void the judgment/treasurer’s deed — i.e., not every statutory deviation is fatal. [Source: azesquire.com (Fleishman Law) Othon/DuPont analysis]
  • Consequence of defective notice: voidable (the judgment may be set aside / deed cancelled) — but only an insubstantial failure is excused, and collateral attack is constrained per Othon (2023).
  • Leading cases: advanced-property-tax-liens-v-othon-2021, advanced-property-tax-liens-v-othon-2023, dupont-v-reuter, mullane-v-central-hanover, mennonite-v-adams, jones-v-flowers, tyler-v-hennepin-county.

7. Title & Marketability

  • Deed warranty level: treasurer’s deed / trustee’s deed convey without warranty (quitclaim-quality); buyer takes the interest foreclosed.
  • Marketable immediately? No — a treasurer’s-deed grantee typically needs to quiet title before the property is readily insurable/marketable; title underwriters commonly require it. (insurer practice — needs_verification.)
  • Quiet title required? Practically yes for tax-deed parcels.
  • SOL to challenge the deed: tax-foreclosure judgments are subject to the collateral-attack limits in Othon (2023) and Rule 60 / statutory limits. (precise statute-of-limitations to attack a treasurer’s deed — needs_verification.)
  • Title insurance availability: generally limited until quiet-title judgment for tax-deed parcels; available post-quiet-title.
  • Common defects: defective/insubstantial-vs-substantial § 42-18202 notice, unrecorded interests (cf. Othon), missed lienholders, redemption disputes, open junior liens after trustee’s sale (which survive only as to surplus, not the parcel).

9. Edge Cases (state-specific notes)

  • bankruptcy-automatic-stay — a Chapter 7/13 filing stays both a § 42-18201 tax-foreclosure action and a § 33-807 trustee’s sale; the 3-year redemption / 10-year foreclosure clocks get a statutory 12-month extension where law or court order barred the action (§ 42-18201). [Source: azleg.gov §42-18201]
  • federal-tax-lien-redemption — the IRS holds a 120-day right to redeem after a sale where a federal tax lien is junior (26 U.S.C. § 7425); state procedure must give the U.S. notice. (interaction with AZ trustee sale — needs_verification.)
  • heirs-property — fractional/heir owners may redeem proportionally under A.R.S. § 42-18151(B). [Source: azleg.gov §42-18151]
  • hoa-super-priority — Arizona HOA assessment liens are not super-priority over a first mortgage in the Nevada sense; HOA-foreclosure surplus follows § 33-812 priority (see Tortosa). [Source: azleg.gov §33-812; Tortosa]
  • anti-deficiency — § 33-814(G) bars deficiency on residential ≤2.5-acre one/two-family dwellings sold by trustee’s sale; fair-value protection is non-waivable. [Source: azleg.gov §33-814]
  • void-vs-voidable — defective tax notice renders a foreclosure judgment voidable, but only a substantial failure matters (DuPont) and collateral attack is limited (Othon 2023).

10. Operations

  • Where records live: county Recorder (deeds, deeds of trust, notices of sale), county Treasurer (tax liens, CPs, redemptions, surplus deposits), Superior Court (foreclosure / surplus actions), Arizona Dept. of Revenue (unclaimed property / escheated surplus > $50).
  • Public portals: county treasurer tax-lien sale sites (Maricopa: treasurer.maricopa.gov; Pima: to.pima.gov; Pinal: treasurer.pinal.gov); azcourts.gov for opinions; azleg.gov for statutes; azdor.gov for unclaimed property.
  • Typical costs: filing/recording fees; trustee’s fees & attorney fees come off the top of trustee-sale proceeds (§ 33-812); tax excess-proceeds sale charges facilitation/qualified-entity costs first (SB1431).
  • Typical timelines: tax lien → 3-year redemption hold before foreclosure; foreclosure must be filed within 10 years; trustee’s sale ≥ ~90 days from notice; trustee-sale surplus claims: 45-day response / 180-day superior- rights hold; surplus escheat after 2 years.
  • Key agencies: County Treasurers, County Recorders, Arizona Superior Court, Arizona Department of Revenue.
  • Useful forms: certificate of purchase; certificate of redemption; § 42-18202 notice of intent to foreclose; notice of trustee’s sale (§ 33-808); § 33-812 application for release of surplus.

2b. Redemption Advanced

Assignability of the Statutory Redemption Right

  • Assignable? Yes. A.R.S. § 42-18151(A)(3) expressly permits redemption by “the owner’s agent, assignee or attorney,” and § 42-18151(A)(4) allows redemption by “any person who has a legal or equitable claim in the property.” These provisions together mean the statutory redemption right can be exercised by an assignee of the owner’s interest. [Source: azleg.gov §42-18151, retrieved 2026-06-02]
  • Restrictions: No restriction on who the owner may assign to; the statute uses the broad phrase “any person.” No court-approval mechanism is required. The assignment must be communicated to the county treasurer (who pays the certificate holder on the “surrender of the certificate of purchase,” per § 42-18155). [Source: azleg.gov §42-18151, §42-18155]
  • Purchase mechanism: A deed of assignment from the owner to the third party; the assignee then redeems through the county treasurer using the same procedure as the owner.
  • Statute/case: A.R.S. § 42-18151(A)(3)–(4). [Source: azleg.gov §42-18151]

Equitable Redemption (Distinct from Statutory?)

  • Distinct from statutory? Arizona’s tax-lien-foreclosure scheme is judicial (Superior Court), so equitable principles apply. Advanced Property Tax Liens v. Othon (2023) confirmed that a court entering a judgment to foreclose the right to redeem cuts off “all legal or equitable right, title or interest in the property” under § 42-18204(C). Pre-judgment, parties with equitable interests may redeem; post-judgment, only appellate remedies remain. [Source: azleg.gov §42-18204(C); Othon 2023]
  • Available pre-sale only? Equitable redemption in the traditional sense (available before a sheriff’s or judicial sale) is conceptually available before the § 42-18201 foreclosure judgment; once the judgment issues, redemption is cut off. For deed-of-trust sales, § 33-813 gives the trustor a right to reinstate only up to 5 p.m. the day before sale — no post-sale equitable right exists. [Source: azleg.gov §33-813]
  • Notes: Arizona has not adopted a standalone “equitable redemption” doctrine separate from its statutory scheme. Needs_verification: whether any Arizona court has applied the classical equitable-redemption doctrine independent of the statutory framework.

Installment Redemption

  • Permitted? Partial redemptions are permitted for fractional interest holders (§ 42-18151(B) — a partial-interest owner may redeem proportionally). Full installment redemption plans are not established in the statutes reviewed. (Needs_verification: whether any county treasurer offers a structured installment redemption plan.)
  • Statute: A.R.S. § 42-18151(B). [Source: azleg.gov §42-18151]

Assignment of Tax Certificate / Deed by the Purchaser (Mid-Redemption)

  • Permitted? Yes. A.R.S. § 42-18118 expressly provides that a certificate of purchase “is assignable by endorsement or as provided by section 42-18121.01,” and assignment must be noted in the county treasurer’s records. The assignee receives “all the right and title of the original purchaser.” [Source: azleg.gov §42-18118, retrieved 2026-06-02]
  • Restrictions: No statutory restriction on who may receive the assignment (broad “any person”); a $10 fee per certificate is charged by the treasurer. [Source: azleg.gov §42-18118]
  • Statute: A.R.S. § 42-18118; A.R.S. § 42-18122 (county treasurer must sell, assign and deliver to “any person who pays”). [Source: azleg.gov §42-18118, §42-18122]

3b. Surplus Advanced

Claim Assignability

  • Full assignment permitted? Yes for mortgage-foreclosure surplus. Arizona courts have recognized assignees pursuing surplus (see Tortosa HOA v. Garcia, 2022, where an assignee of a senior lien litigated surplus distribution). A.R.S. § 33-812 does not prohibit assignment of a surplus claim; it specifies the claim process for “any person who claims a right to the proceeds,” broad enough to encompass assignees. [Source: azleg.gov §33-812; Tortosa case descrybe.ai]
  • For tax-foreclosure excess proceeds: A.R.S. § 42-18204(D)(3) states the owner “retains interest in the excess proceeds” after a foreclosure judgment; this property right is presumptively assignable under general Arizona property-law principles. (Needs_verification: no Arizona case or statute specifically addresses assignment of a § 42-18204 excess-proceeds right, as opposed to a § 33-812 trustee-sale surplus claim.)
  • Assignment vs. fee agreement: Arizona has no statute capping or defining the distinction between a fee agreement and a full assignment of excess-proceeds claims. The distinction is governed by general contract law. (Needs_verification: no Arizona consumer-protection statute specifically governing “excess proceeds finders” or claim assignment agreements was located.)
  • Fee cap on assignments: No Arizona statute caps the fee a third-party recovery agent may charge or assigns the surplus-claim recovery obligation. (Needs_verification: no fee-cap statute located.)
  • Statute: A.R.S. § 33-812; A.R.S. § 42-18204. [Source: azleg.gov §33-812, §42-18204]

Statute of Limitations on Surplus Claims

  • Trustee’s-sale surplus (§ 33-812): The operative limitation is the 2-year abandonment rule — funds are “presumed abandoned if the monies remain with the treasurer for at least two years from the date of deposit” (§ 33-812(L)). After 2 years with no pending application, funds ≤$50 transfer to the county general fund; funds >$50 transfer to the Arizona Department of Revenue under unclaimed-property law. Trigger date: date of deposit with the county treasurer. [Source: azleg.gov §33-812(L), retrieved 2026-06-02]
  • Response deadline: Before the 2-year escheat period runs, any person claiming the proceeds must file a response within 45 days of the latest mailing of the trustee’s application (§ 33-812(I)). [Source: azleg.gov §33-812(I)]
  • Tax-foreclosure excess proceeds (§ 42-18204): No express limitation period was located in the statute text reviewed. (Needs_verification: whether an Arizona statute establishes an express limitation period for claiming § 42-18204 excess proceeds from the county treasurer.)
  • Citation: A.R.S. § 33-812(L), (I). [Source: azleg.gov §33-812]

Competing Claimant Procedure

  • Interpleader used? Yes. Under § 33-812(G), when competing claims exist the trustee may deposit surplus with the county treasurer and file a civil action naming the treasurer; the court then determines entitlement. [Source: azleg.gov §33-812(G)]
  • Filing race? Not a pure filing-race system. Priority is governed by lien priority rules, not filing order. [Source: azleg.gov §33-812; Tortosa — “liens attach to the surplus in their pre-foreclosure priority”]
  • Priority rules: Lienholders are paid in priority order; the former owner receives the remainder. Where a superior claimant appears, the court “shall not issue an order on the proceeds until one hundred eighty days from the date the complaint was filed” (§ 33-812(J)). [Source: azleg.gov §33-812(J)]
  • Citation: A.R.S. § 33-812(G), (J); Tortosa HOA v. Garcia (2022). [Source: azleg.gov §33-812; descrybe.ai Tortosa]

Deceased Owner Procedure

  • Probate required first? No explicit Arizona statute requires a probate proceeding before an heir may claim mortgage-foreclosure surplus under § 33-812. The statute uses the general phrase “any person who claims a right to the proceeds.” However, where the owner is deceased, establishing standing to claim (i.e., as a personal representative or heir) as a practical matter requires proof of authority. (Needs_verification: no Arizona case or authoritative guidance on whether a personal representative must be appointed before an heir may directly claim § 33-812 or § 42-18204 excess proceeds.)
  • Personal representative has standing? Yes — a probate personal representative would qualify under “any person who claims a right to the proceeds” and could present letters of administration.
  • Direct heir claim? Arizona’s community property and probate law (Title 14) governs; a direct heir claim without letters of administration is legally uncertain for contested surplus. (Needs_verification.)
  • Notes: For smaller surplus amounts, county treasurers may have informal procedures allowing heirs with an affidavit of heirship to claim without a full probate proceeding (pursuant to A.R.S. § 14-3971, the small-estate affidavit procedure for estates under $75,000). (Needs_verification: county practice.)

Fraudulent Conveyance Exposure

  • Assignment voidable by creditors? Yes — an assignment of a surplus claim by an insolvent owner for less than reasonably equivalent value would be voidable under Arizona’s Uniform Fraudulent Transfer Act (UFTA), A.R.S. §§ 44-1001 et seq. Under A.R.S. § 44-1004(A), a transfer made with “actual intent to hinder, delay or defraud any creditor” or made without reasonably equivalent value by an insolvent debtor is voidable by creditors. [Source: azleg.gov §44-1004, retrieved 2026-06-02]
  • Applicable statute: A.R.S. § 44-1004 (UFTA). [Source: azleg.gov §44-1004]
  • Statute of limitations for avoidance: Actual-fraud claims: 4 years from the transfer or 1 year from discovery, whichever is later (§ 44-1009); constructive-fraud claims: 4 years from the transfer (§ 44-1009). [Source: azleg.gov §44-1009, retrieved 2026-06-02]
  • Notes: A recovery-agent agreement that assigns the full surplus claim outright (not merely a contingency-fee agreement) in exchange for below-market consideration from an insolvent former owner is potentially voidable. Practitioners typically use a fee-based representation agreement rather than an outright assignment to reduce this risk.

Court Notice to Lienholders

  • Court must notify lienholders? Under § 33-812, the trustee must mail the application to interested parties. For tax-foreclosure excess-proceeds sales under § 42-18204 / SB1431, notice is by certified mail, recording, posting, publication, and MLS listing. [Source: azleg.gov §33-812; §42-18204 / SB1431 fact sheet]
  • Method: Certified mail + publication + posting + recording (tax excess-proceeds sale); mailed application (trustee-sale surplus).
  • Timeline: Responses due within 45 days of last mailing for trustee-sale surplus (§ 33-812(I)).
  • Citation: A.R.S. § 33-812(I); A.R.S. § 42-18204 (SB1431 procedure). [Source: azleg.gov §33-812, §42-18204]

5b. Title Advanced

Quiet Title

  • When required? Practically required for a treasurer’s deed grantee who wants marketable, insurable title. A treasurer’s deed (quitclaim quality) carries no warranty, and title underwriters will not insure a tax-deed parcel without a quiet-title judgment in most circumstances. The quiet-title action cures notice defects and eliminates competing claims in a way the treasurer’s deed alone cannot. [Source: Module 7 above; §12-1101 (action “may be brought”); practical standard per title-industry practice]
  • Action type: Judicial — A.R.S. §§ 12-1101 through 12-1103 provide the quiet-title framework; filed in Superior Court in the county where the property is located. The action is a civil lawsuit, not an administrative proceeding. [Source: azleg.gov §12-1101, §12-1102, §12-1103, retrieved 2026-06-02]
  • Court with jurisdiction: Superior Court (the trial court of general jurisdiction in Arizona) in the county where the real property is situated.
  • Typical timeline: 4–12 months for an uncontested quiet-title action; 12–24+ months if contested or if parties must be served by publication. Publication service requires 4 consecutive weekly publications plus 60 days for a response. (Needs_verification: no Arizona statute sets a specific quiet-title timeline; range is based on general civil procedure and practitioner experience.)
  • Typical cost range: Uncontested: $2,000–$6,000 in attorney fees plus court costs; contested: $10,000–$30,000+. (Needs_verification: no official cost schedule; range is representative.)
  • Cures all pre-sale defects? A quiet-title judgment entered by a court of competent jurisdiction is binding on all parties served or constructively noticed, and extinguishes adverse claims in the property. Defects arising from the original tax-lien-foreclosure proceeding (e.g., defective § 42-18202 notice) can be cured if the interested parties are properly joined and served in the quiet-title action. However, Othon (2023) limits collateral attack to those whose interests were not properly before the foreclosure court. [Source: azleg.gov §12-1101; Othon 2023]
  • Citation: A.R.S. §§ 12-1101, 12-1102, 12-1103. [Source: azleg.gov §12-1101, §12-1102, §12-1103]

Deed Seasoning

  • Title insurers require seasoning? In practice, yes — most major title underwriters will not insure a treasurer’s deed for a stated period (commonly 3–5 years) without a quiet-title judgment, because of the risk of a void-deed claim from defective notice. (Needs_verification: no binding title-industry rule; seasoning practice varies by underwriter and circumstances.)
  • Typical years: 3–5 years from the issuance of the treasurer’s deed, or alternatively, immediately post-quiet-title judgment regardless of deed age. (Needs_verification.)
  • Rationale: Risk that the § 42-18202 notice was defective — a “substantial” failure could void the deed (DuPont v. Reuter distinguished); risk of unrecorded interests that survived the foreclosure (Othon 2023 limits collateral attack, but does not eliminate it for parties who were never served).

Title Insurance

  • Immediate availability? No for raw treasurer’s-deed parcels without a quiet-title judgment in most underwriter practices.
  • Conditions for immediate issuance: Some underwriters may issue a title policy immediately if: (a) quiet title is already obtained; (b) sufficient seasoning has passed; or (c) the parcel has very low risk (e.g., no recorded competing liens). (Needs_verification: underwriter-specific.)
  • Insurers known to write: Major underwriters (Fidelity National, First American, Old Republic, Stewart) operate in Arizona; willingness to insure tax-deed parcels varies by underwriter and local office. (Needs_verification: specific underwriter policies.)
  • Quitclaim or special warranty only? The treasurer’s deed itself is quitclaim-quality; a title policy, if issued, covers the insured’s interest but with exceptions typical for tax sales.

Marketable Title Act

  • Exists? Arizona does not have a Marketable Title Act in the sense adopted by Iowa, Michigan, or Florida. Arizona’s title marketability is governed by the general recording act (race-notice, Title 33, Ch. 4) and common-law chain-of-title principles. (Needs_verification: confirm no Arizona MTA statute exists; a search of Title 33 did not reveal an MTA provision.)
  • Lookback years: Not applicable (no MTA).
  • Statute: N/A. [Source: Title 33 review — no MTA provision located, 2026-06-02]

Judicial Confirmation

  • Required before deed issues? No for trustee’s-deed sales — they are final without judicial confirmation (§ 33-807; no upset-bid or confirmation period exists). No for tax-lien-foreclosure deeds either — the foreclosure judgment itself (entered by the Superior Court) is what authorizes the treasurer to issue the deed; the deed issues ministerially after judgment (§ 42-18205). [Source: azleg.gov §42-18205, §33-807]
  • Tribunal: Superior Court (for the § 42-18201 foreclosure judgment).
  • Timeline: The foreclosure judgment is the culmination of the § 42-18201 action; no separate confirmation proceeding occurs post-judgment.
  • Citation: A.R.S. § 42-18205 (deed issued after presenting certified judgment + $50 fee); A.R.S. § 33-807 (trustee’s sale final). [Source: azleg.gov §42-18205, §33-807]

Chain-of-Title Cure

  • Depth: A quiet-title judgment cures claims based on defects in the tax-lien-foreclosure proceeding (notice defects, missed parties) if those parties are served or constructively noticed in the quiet-title action. It does not cure federal tax liens where the IRS was not given § 7425 notice before the sale. It does not cure CERCLA/environmental liens (discussed in Module 7b). Assessment liens under Title 48 and § 9-276 expressly survive under § 42-18115. [Source: azleg.gov §42-18115, §42-18204(D)]
  • Notes: Pre-existing easements survive the tax-lien foreclosure by statute (§ 42-18204(D)(1)).

5c. TRO & Injunctive Relief

Recognized Grounds to Halt a Tax or Mortgage Foreclosure Sale

For trustee’s-sale (deed-of-trust) foreclosures:

  • Defective § 33-809 notice (missed parties)
  • Invalid acceleration or breach of the loan agreement
  • Payment dispute (dispute that the debt is in default)
  • SCRA protection (active-duty military servicemember)
  • Bankruptcy automatic stay (already operative or to be obtained)
  • Constitutional violation (due process, equal protection)
  • Fraud or misrepresentation in the origination or servicing of the loan

For tax-lien-foreclosure actions (judicial):

  • Improper § 42-18202 pre-suit notice (jurisdictional defect — Othon 2021)
  • Payment dispute (taxes already paid / redemption tendered)
  • Bankruptcy automatic stay
  • Constitutional / Tyler-based challenge

[Source: azleg.gov §33-811(C); §42-18202; Othon 2021]

  • Standard: Arizona Rule of Civil Procedure Rule 65 governs temporary restraining orders and preliminary injunctions. The moving party must demonstrate: (1) likely success on the merits; (2) irreparable harm; (3) balance of hardships favors granting relief; and (4) public policy is not disserved. This is the standard 4-part PI test. [Source: Ariz. R. Civ. P. 65; azleg.gov §33-811(C) cross-references “rule 65”]
  • A.R.S. § 33-811(C) makes Rule 65 the exclusive vehicle for stopping a trustee’s sale: the required order “granting relief pursuant to rule 65” must be entered and delivered to the trustee before 5:00 p.m. on the last business day before the sale.

Court with Jurisdiction

Arizona Superior Court in the county where the property is located. For trustee’s-sale cases, the plaintiff files the Rule 65 motion in Superior Court. For tax-lien-foreclosure cases (already in Superior Court), the motion is filed within the pending § 42-18201 action. [Source: azleg.gov §33-811; §42-18201]

Bond Required

  • Explicitly required? A.R.S. § 33-811(C) does not expressly require a bond, but Arizona Rule of Civil Procedure Rule 65(c) requires a party obtaining a preliminary injunction or TRO to give security “in such sum as the court deems proper.” Bond is therefore required under Rule 65(c) unless waived by the court. [Source: Ariz. R. Civ. P. 65(c); §33-811(C)]
  • Typical amount: At the court’s discretion based on harm to the opposing party; for real property, courts may set bond at the estimated loss to the foreclosing party (e.g., carrying costs, lost interest). (Needs_verification: no standard Arizona bond schedule for foreclosure TROs.)

Emergency Timeline

  • Timing: An ex parte TRO under Rule 65(b) can be obtained the same day or within 24–48 hours of filing if the moving party demonstrates immediate irreparable harm and files a properly supported motion. The order and supporting documents must be “delivered to the trustee within twenty-four hours” of entry (§ 33-811(C)). [Source: azleg.gov §33-811(C)]
  • Critical deadline: The order must be entered and delivered to the trustee before 5:00 p.m. mountain standard time on the last business day before the scheduled sale date. Filing the motion is not enough — the order must issue and be delivered. [Source: azleg.gov §33-811(C), retrieved 2026-06-02]

Effect on a Completed Sale

  • Sale completed before the TRO issued: Under A.R.S. § 33-811(C), anyone who fails to obtain a court order under Rule 65 before the sale deadline “shall waive all defenses and objections to the sale not raised in” that action. If the sale completes without a pre-sale order, the trustee’s deed is generally final and not subject to post-sale collateral attack on grounds that could have been raised pre-sale. [Source: azleg.gov §33-811(C)]
  • Equitable post-sale relief: Extreme misconduct (fraud on the court, SCRA violations) may still support post-sale relief in extraordinary circumstances, but Arizona courts view the pre-sale filing requirement strictly.

Non-Judicial Foreclosure Notes (Trustee’s Sale)

In Arizona’s non-judicial trustee’s-sale system, the trustee is not required to go to court, so the owner/borrower must affirmatively seek a Rule 65 order. The burden is entirely on the party seeking to stop the sale. Failure to obtain the order by the deadline constitutes a waiver of all defenses that were or could have been raised. [Source: azleg.gov §33-811(C)]

Leading Cases

7b. Lien Survival & Purchaser Exposure

IRS 120-Day Redemption (26 U.S.C. § 7425)

  • Applies in Arizona? Yes — 26 U.S.C. § 7425(d)(1) grants the United States a right to redeem real property sold to satisfy a lien that has priority over a federal tax lien, including sales made pursuant to a nonjudicial sale under a statutory lien (§ 7425(b)). Both Arizona trustee’s sales (non-judicial) and Arizona tax-lien foreclosures fall within the scope of § 7425. [Source: law.cornell.edu §7425, retrieved 2026-06-02]
  • Period: 120 days from the date of sale or the period allowable for redemption under local law, whichever is longer. (§ 7425(d)(1)) [Source: 26 U.S.C. § 7425(d)(1)]
  • Procedure: The IRS must be given 25 days’ advance written notice before the sale (by registered/certified mail or personal service to the Secretary of the Treasury) for the lien to be dischargeable by the sale (§ 7425(b)). If proper notice was not given, the federal lien is not discharged by the sale. The IRS redemption is exercised by paying the amount paid at the sale plus interest at 6% per annum. [Source: 26 U.S.C. § 7425(b), (d); IRS Pub. 783]
  • Citation: 26 U.S.C. §§ 7425(b), (d). [Source: law.cornell.edu §7425]

HOA Super-Priority

  • Super-priority exists in Arizona? No. Arizona HOA assessment liens do not have super-priority over a first mortgage or first deed of trust. Both the planned-community statute (A.R.S. § 33-1807) and the condominium statute (A.R.S. § 33-1256) expressly subordinate HOA liens to recorded first mortgages/deeds of trust and to real estate tax/governmental liens. [Source: azleg.gov §33-1807, §33-1256, retrieved 2026-06-02]
  • Statute: A.R.S. § 33-1807 (planned communities); A.R.S. § 33-1256 (condominiums).
  • Cap: Not applicable (no super-priority).
  • Survives tax sale? No — A.R.S. § 33-1256 explicitly states the HOA lien is subordinate to “Liens for real estate taxes and other governmental assessments or charges against the unit.” A tax-lien foreclosure that destroys junior liens would eliminate an HOA lien that is junior to the tax claim. [Source: azleg.gov §33-1256]
  • Survives mortgage foreclosure (trustee’s sale)? As a junior lien only — HOA liens rank behind the first deed of trust; a trustee’s sale by the first lender extinguishes the HOA lien. The HOA lien may have a claim to surplus under § 33-812(A)(4) (HOA/condo subordinate liens on written claim). [Source: azleg.gov §33-812(A)(4), §33-1807]
  • Leading cases: tortosa-homeowners-association-v-garcia-2022 (surplus distribution — senior lienholder not entitled to junior-foreclosure excess proceeds; surplus to junior lienors then owner)

Environmental Liens (CERCLA / State Superfund)

  • CERCLA lien survives tax sale? CERCLA § 107(l) creates a federal lien for response costs on all real property of the liable party. Under 26 U.S.C. § 6323 priority rules, a CERCLA/federal lien may survive a tax sale if the IRS/United States was not given proper § 7425 notice before the sale. A prudent purchaser must search for recorded CERCLA/EPA notices of federal tax liens. [Source: 42 U.S.C. § 9607(l); 26 U.S.C. § 7425]
  • State superfund superlien? No Arizona state “superlien” statute (one that would grant state environmental cleanup costs priority over pre-existing first mortgages) was located in the statutory review. Arizona’s remedial-action cost-recovery scheme (A.R.S. §§ 49-282 to 49-285) creates personal liability for responsible parties but does not appear to create a super-priority lien on real property superior to pre-existing mortgages. (Needs_verification: confirm absence of a state environmental superlien.)
  • Notes: CERCLA federal liens perfected after a first mortgage are subordinate to that mortgage but may survive a junior-lien foreclosure. Purchasers at tax sales should search federal lien records (UCC/lien search at county recorder + IRS FOIA) and conduct Phase I environmental assessment for industrial/commercial parcels.

Municipal Code / Blight Liens

  • Survive tax sale? Yes — A.R.S. § 42-18115 expressly provides that “the sale of a real property tax lien does not extinguish any lien for an assessment levied pursuant to title 48, chapter 4, 6 or 14, or section 9-276.” Section 9-276 governs municipal civil code enforcement liens. Assessment liens under Title 48 (improvement/special district assessments) also survive by statute. [Source: azleg.gov §42-18115, retrieved 2026-06-02]
  • Statute: A.R.S. § 42-18115; A.R.S. § 9-276.
  • Notes: Municipal nuisance-abatement and blight liens recorded under § 9-276 are not extinguished by a tax-lien sale. Purchasers should search the municipal records of the city or town where the property is located for outstanding code-enforcement liens before bidding.

Mechanic’s Liens

  • Survive tax sale if noticed? Mechanic’s and materialmen’s liens (A.R.S. §§ 33-981 et seq.) that are perfected (recorded) before the tax-lien-sale date may be treated as encumbrances on the property. However, § 42-18115 does not expressly protect mechanic’s liens in the same way it protects Title 48 assessment liens. (Needs_verification: whether a perfected mechanic’s lien survives an Arizona tax-lien sale or is extinguished by the superior tax claim.)
  • Notes: A tax lien has priority over most other liens by statute (A.R.S. § 42-17153); a mechanic’s lien filed after the tax-lien attachment date is typically junior and subject to extinguishment.

Junior Mortgage Purchaser Exposure

  • Takes subject to senior? For trustee’s sales: the purchaser at a first-lien trustee’s sale takes free of junior deeds of trust/mortgages (they are extinguished, subject to surplus rights). The purchaser at a junior-lien trustee’s sale takes subject to the senior mortgage. For tax-lien foreclosures: the treasurer’s deed conveys the tax-lien interest; liens with priority over the tax lien (typically federal tax liens if not properly noticed) may survive. [Source: azleg.gov §33-812; §42-18115]
  • Common mistake: Bidders at junior-lien trustee’s sales sometimes fail to account for the outstanding senior mortgage balance, resulting in a property acquisition burdened by senior debt.

Due Diligence Required Before Bidding

  1. Title search / title report from county recorder records.
  2. IRS/federal lien search (IRS notice under § 7425; UCC + federal lien index at county recorder).
  3. Environmental screening: Phase I ESA for commercial/industrial parcels; EPA Superfund site list check (CERCLIS).
  4. HOA status and outstanding assessments (HOA lien may attach to surplus but not super-priority over first deed of trust).
  5. Municipal code-enforcement lien search with the city/town government.
  6. Title 48 assessment lien search (special districts, improvement district).
  7. Outstanding senior mortgage balance (for junior-lien sales).
  8. Bankruptcy court search (PACER) for automatic stays.
  9. SCRA check for active-duty military occupants.

10b. Purchaser Obligations During the Redemption Period

Must the Purchaser Pay Subsequent Taxes?

  • Required? Yes, permissively. A.R.S. § 42-18121 provides that a certificate-of-purchase holder may present the CP to the county treasurer after June 1 of each subsequent year and pay the next year’s taxes; the treasurer records the payment and issues a new certificate or endorsement. While the CP holder is not required by statute to pay subs, failure to do so allows the subsequent-year taxes to remain unpaid, potentially creating a senior lien or allowing another party to acquire a subsequent-year CP. [Source: azleg.gov §42-18121, retrieved 2026-06-02]
  • Consequence of failure: A third party may acquire a certificate of purchase for the subsequent year’s taxes, creating a competing lien and redemption right. The original CP holder’s foreclosure action must consolidate all CPs.
  • Citation: A.R.S. § 42-18121. [Source: azleg.gov §42-18121]

Must the Purchaser Notify the Owner Before Redemption Expiration?

  • Required? Yes — under A.R.S. § 42-18202, the CP holder must send a certified-mail notice (to the owner’s mailing address per county assessor records, the situs address, and any tax-bill mailing address) at least 30 days and not more than 180 days before filing the foreclosure action. This notice is the practical mechanism by which owners learn their right to redeem is about to be cut off. The notice must state the proposed filing date and include the statutory warning that the owner “must request an excess proceeds sale” if they believe the property has value beyond the tax burden. [Source: azleg.gov §42-18202, retrieved 2026-06-02]
  • Form: Written certified-mail notice containing: owner’s name; tax parcel ID; assessor’s property description; CP number; proposed filing date; and the statutory warning language.
  • Timing: At least 30 days before filing the § 42-18201 action; no more than 180 days before filing.
  • Consequence of failure: “A court may not enter any judgment to foreclose the right to redeem” until proper notice is sent (Othon 2021 — the notice is jurisdictional). [Source: azleg.gov §42-18202; Othon 2021]
  • Citation: A.R.S. § 42-18202. [Source: azleg.gov §42-18202]

Owner’s Right to Remain in Possession

  • Owner may remain? Yes — a tax-lien CP does not convey a possessory interest. Title remains in the owner during the entire redemption period; the CP is a lien on title only, not a transfer of possession. The owner retains the right to occupy the property, collect rents, and manage it until the foreclosure judgment is entered and a treasurer’s deed is delivered. [Source: Tax-lien framework, A.R.S. Title 42 Ch. 18; deed does not issue until after judgment (§42-18205)]
  • Purchaser may enter? No — the CP holder has no right of entry or possession during the redemption period. Entering or disturbing the owner’s possession would be trespass.
  • Citation: Implied by the structure of the Arizona tax-lien scheme (lien only, not deed); A.R.S. § 42-18205 (deed issues only after foreclosure judgment). [Source: azleg.gov §42-18205]

Costs Collectible Upon Redemption

  • Bid + interest? Yes — the redeeming owner must pay: (1) the amount the CP was purchased for + interest at the CP rate (A.R.S. § 42-18153(A)(1)). [Source: azleg.gov §42-18153, retrieved 2026-06-02]
  • Subsequent taxes? Yes — all subsequent taxes paid by the CP holder and endorsed on the certificate, with interest at the same CP rate (§ 42-18153(A)(2)). [Source: azleg.gov §42-18153]
  • Documented improvements? No — Arizona’s tax-lien scheme does not provide for the CP holder to collect reimbursement for improvements made to the property during the redemption period.
  • Other costs? Statutory fees paid by the CP holder “in connection with the certificate” (excluding the processing fee under § 42-18116(C)); and — if a § 42-18202 pre-foreclosure notice was recorded and redemption occurs after that notice — costs including the title-report cost, interest-identification costs, and attorney fees (§ 42-18206). [Source: azleg.gov §42-18153, §42-18206]
  • Citation: A.R.S. § 42-18153; A.R.S. § 42-18206. [Source: azleg.gov §42-18153, §42-18206]

Property Maintenance Obligation

  • Required? No affirmative maintenance obligation is imposed on the certificate-of-purchase holder by Arizona statute during the redemption period. The owner remains in possession and title and is responsible for maintenance and property taxes. (Needs_verification: no Arizona statute imposing a CP-holder maintenance duty was located.)

11b. Restrictions & Special Rules

Entity Purchase Restrictions

  • Natural persons only? No. Arizona statutes do not restrict tax-lien-certificate purchases to natural persons. A.R.S. § 42-18118 states the certificate “is assignable by endorsement” to any person; § 42-18122 requires the treasurer to deliver a CP to “any person who pays.” For trustee’s sales, A.R.S. § 33-810 states “Any person, including the trustee or beneficiary, may bid at the sale.” [Source: azleg.gov §42-18118, §42-18122, §33-810]
  • LLC permitted? Yes. No prohibition on LLCs, corporations, or other business entities purchasing tax liens or bidding at trustee’s sales was found in Arizona statutes.
  • Foreign entity permitted? Yes — no residency or citizenship restriction on purchasers was located. (Needs_verification: confirm no Arizona statute restricts foreign-entity ownership of tax-lien certificates.)
  • Notes: Institutional investors routinely purchase Arizona tax-lien certificates.
  • Citation: A.R.S. § 42-18118; A.R.S. § 42-18122; A.R.S. § 33-810. [Source: azleg.gov §42-18118, §42-18122, §33-810]

Insider Prohibition

  • Who is prohibited? No specific Arizona statute prohibiting county employees, county treasurers, or their relatives from purchasing tax-lien certificates at the auction was located in the statutes reviewed. (Needs_verification: Arizona conflict-of-interest statutes (A.R.S. § 38-501 et seq.) may apply to county officers; no specific tax-lien-sale prohibition located.)
  • Scope: General conflict-of-interest law (A.R.S. §§ 38-501 to 38-511) would prohibit a public officer from using their official position to obtain a personal financial benefit. Whether this bars a county treasurer from purchasing at their own sale is not addressed by a specific statute. (Needs_verification.)
  • Citation: A.R.S. §§ 38-501 to 38-511 (general conflict-of-interest); no specific tax-lien-sale insider prohibition statute located. [Source: review of A.R.S. Title 42 Ch. 18, 2026-06-02]

Right of First Refusal

  • Municipalities / CDCs / land banks? No — Arizona does not appear to have a statutory right of first refusal for municipalities, community development corporations, or land banks at tax-lien or trustee’s-sale auctions. (Needs_verification: no ROFR statute located in Title 42 Ch. 18 or related statutes.)
  • Match window: N/A.
  • Citation: None located. (Needs_verification.) [Source: review of A.R.S. Title 42 Ch. 18, 2026-06-02]

Land Bank Program

  • Exists? Arizona does not have a well-established statewide land-bank statute comparable to Michigan’s Land Bank Fast Track Act or Ohio’s land-bank system. Some Arizona municipalities (e.g., Phoenix) operate informal land-assemblage programs, but no statewide land-bank statute was identified in the statutes reviewed. (Needs_verification: confirm absence of a statewide Arizona land-bank statute; check for recent legislation such as HB/SB enacted after 2023.)
  • Name: Not established. (Needs_verification.)
  • Statute: Not identified. (Needs_verification.)
  • Receives unsold properties? Unclear. Under § 42-18113, liens unsold at the annual auction are “struck to the state” (assigned to the state at 16%); these liens may eventually be handled through the county attorney’s foreclosure process (§ 42-18207), but no land-bank program for the resulting parcels was found. (Needs_verification.)
  • Operational notes: (Needs_verification.)

Deficiency Judgment

  • Permitted after tax sale? There is no deficiency judgment mechanism in Arizona’s tax-lien-foreclosure scheme. The § 42-18201 action forecloses the right to redeem — it does not generate a personal judgment against the former owner for the tax debt beyond what is recovered from the sale. Any remaining tax debt after the lien is satisfied would be addressed through the normal tax-collection mechanism, not a deficiency action. (Needs_verification: confirm no specific Arizona statute authorizing a deficiency judgment against the former owner after a tax excess-proceeds sale.)
  • Permitted after mortgage foreclosure (trustee’s sale)? Yes, with limits. A.R.S. § 33-814(A) allows a deficiency action filed within 90 days of the trustee’s sale. The deficiency is the total debt minus the greater of fair market value or sale price on the sale date. [Source: azleg.gov §33-814]
  • Fair-value defense? Yes — the fair-market-value offset at § 33-814(A) is mandatory and cannot be waived by private agreement (Arizona Supreme Court).
  • Citation: A.R.S. § 33-814(A), (D). [Source: azleg.gov §33-814]

Anti-Deficiency Statute

  • Exists? Yes — two distinct anti-deficiency protections:
    1. A.R.S. § 33-814(G): For residential property of 2.5 acres or less “limited to and utilized for either a single one-family or a single two-family dwelling” sold by trustee’s sale — no deficiency action lies against the trustor. [Source: azleg.gov §33-814]
    2. A.R.S. § 33-729: For purchase-money mortgages on the same class of property (≤2.5 acres, one/two-family residential) — if foreclosure proceeds are insufficient, the “judgment may not otherwise be satisfied out of other property of the judgment debtor.” [Source: azleg.gov §33-729]
  • Scope: Both statutes cover only residential property of the described size and use. The § 33-814(G) exceptions apply to post-2014 deeds of trust on properties owned by residential construction businesses, never completed, or never utilized as a dwelling.
  • Citation: A.R.S. § 33-814(G); A.R.S. § 33-729. [Source: azleg.gov §33-814, §33-729]

One-Action Rule

  • Exists? Arizona is not a strict one-action state in the California sense. Arizona does not have a statute that requires a lender to exhaust one remedy before pursuing another (e.g., foreclose OR sue on the note). However, the 90-day deficiency-action deadline (§ 33-814(A)) effectively limits the lender’s deficiency remedy — if no action is filed within 90 days after the trustee’s sale, the sale proceeds are “deemed to be in full satisfaction” of the debt (§ 33-814(D)), which functions as a practical one-action outcome. [Source: azleg.gov §33-814]
  • Citation: A.R.S. § 33-814(A), (D). [Source: azleg.gov §33-814]
  • Notes: The practical effect is: if the lender elects the trustee’s sale and fails to timely sue for deficiency, the debt is extinguished. For purchase-money mortgages on qualifying residential property, § 33-729 bars deficiency entirely, regardless of whether the lender sues on the note or forecloses first. (Needs_verification: precise characterization of Arizona’s “one-action” status compared to strict one-action states — the existing needs_verification flag is carried forward.)

Who this page is for

▸ For Investors / Operators — Start with §1 (the bid-down-interest CP auction, 16% ceiling, unsold liens struck to the state at 16%), §2/2b (the 3-year redemption that runs until a treasurer’s deed is delivered, and CP assignment mechanics), §5b (path to marketable title — a § 12-1103 Superior Court quiet title; the § 42-18205 deed issues ministerially after the foreclosure judgment but typically needs quiet title before it is insurable), §7b (liens that survive — § 42-18115 assessment liens, the IRS § 7425 120-day redemption, and the absence of HOA super-priority), and §11b (entity eligibility and the § 33-814 deficiency framework).

▸ For Former Owners — Start with §3 (the post-Tyler § 42-18204 excess-proceeds sale — you may request the court to order it where the price is likely to exceed the CP holder’s costs by more than $2,500, and the judgment does not extinguish your interest in the excess; for a trustee’s-sale surplus, the § 33-812 application-and-response procedure with a 45-day response window and 2-year abandonment), §2 (redemption through the county treasurer within the 3-year window), and §5c (grounds, bond, and procedure for an emergency motion to halt a scheduled sale).
