South Dakota — Tax & Mortgage Foreclosure

Legal information, not legal advice. Verify against the cited primary sources before acting. Last verified: 2026-06-02.

South Dakota is a tax-certificate (tax-lien) state whose back-end was reformed in 2024 by HB 1090 to comply with tyler-v-hennepin-county. When real-property taxes go delinquent, the county treasurer offers a tax certificate for each parcel at a public sale and the certificate is struck off to the bidder offering the lowest rate of interest (a bid-down-interest auction), with 10% per year the statutory maximum valid bid (SDCL 10-23-8). Critically, since July 1, 2006 most counties no longer sell certificates to private investors at all — unless the board of county commissioners adopts a resolution waiving the prohibition, the county itself is the holder of the tax certificate (SDCL 10-23-28.1). A certificate holder (county or private) may begin proceedings to procure a tax deed only after three years from the date of the tax-certificate sale, and within six years of it (SDCL 10-25-1). Before a deed can issue, the holder must serve a notice of intention to take tax deed on the owner of record, the occupant, the person in whose name the property is taxed, and recorded mortgagees/lienholders (SDCL 10-25-2 through 10-25-7); the right of redemption does not expire until 60 days after the affidavit of completed service is filed (SDCL 10-25-8). Redemption is made by paying the certificate amount plus interest at the bid rate and subsequent taxes with like interest (SDCL 10-24-1).

The historically important change is on the equity / surplus side. Pre-2024, South Dakota was on the national “equity theft” list — the county (or assignee) took a tax deed and kept the entire value of the property, returning no surplus to the former owner. HB 1090 (SL 2024, ch 38, effective Feb. 12, 2024) now requires that whoever acquires a tax deed must sell the property: a county must declare it surplus and sell it (public auction under ch. 6-13, or by broker) within one year (SDCL 10-25-39.1), and any non-county tax-deed holder must likewise sell it at public auction within one year (SDCL 10-25-39.2). After expenses, taxes, penalty, interest, county liens and costs are paid, any surplus must be returned to the prior owner of record; if the owner cannot be found within 180 days, the surplus goes to the Unclaimed Property Division under ch. 43-41B (SDCL 10-25-39, as amended by SL 2025 ch 49). That makes South Dakota reformed_post_Tyler / compliant for tax foreclosures occurring after the 2024 effective date.

Mortgage debt is foreclosed either judicially (Title 21, Ch. 47) or non-judicially by advertisement (Title 21, Ch. 48), with a post-sale redemption period of one year in the ordinary case (180 days for a “short-term redemption mortgage”; reducible to 60 days for abandoned property) (SDCL 21-52-11, 21-49-30, 21-49-13(8)). Deficiency judgments are allowed but subject to a fair-market- value offset when the mortgagee is the purchaser (SDCL 21-48-14 for advertisement; SDCL 21-47-16/-17 for judicial).

0. Identity & Classification

  • Recording unit: county (count: 66 counties). [Source: general knowledge of SD’s 66 counties — official count cite flagged in needs_verification.]
  • Tax sale type: tax-lien / tax certificate, converting to a tax deed after the redemption period. The county is the default certificate holder post- 2006 unless a county waives the bar (SDCL 10-23-28.1). [Source: sdlegislature.gov — SDCL 10-23-8, 10-23-28.1]
  • Tax foreclosure process: administrative — the county treasurer issues the tax deed after the statutory notice-of-intention procedure; no court judgment is required to vest title (SDCL 10-25-1, 10-25-8, 10-25-11). A separate quiet-title action clears the deed (SDCL 10-25-24, Title 21 ch. 42). [Source: sdlegislature.gov — SDCL 10-25-1, 10-25-8, 10-25-11]
  • Mortgage foreclosure process: both — judicial (Title 21, Ch. 47) and non-judicial foreclosure by advertisement (Title 21, Ch. 48). [Source: alllaw.com (Nolo) summary citing SDCL 21-47, 21-48]
  • Selling authority: county treasurer (tax certificate sale, redemption, tax deed); county / county commissioners (post-deed surplus auction under SDCL 10-25-39.1); sheriff (judicial foreclosure sale); the party foreclosing by advertisement (Title 21, Ch. 48 sale).
  • Statutory home:
  • Tyler v. Hennepin compliance: reformed_post_Tyler / compliant. HB 1090 (SL 2024, ch 38) added SDCL 10-25-39.1 and 10-25-39.2 (mandatory sale within one year by both county and non-county tax-deed holders) and amended SDCL 10-25-39 to return surplus to the prior owner of record (180-day window, then Unclaimed Property). Before this, SD retained the full value and was listed among “equity theft” states. [Source: sdlegislature.gov — SDCL 10-25-39, 10-25-39.1, 10-25-39.2; mylrc.sdlegislature.gov HB 1090 (2024); Impact for Equity multi-state analysis]

1. Tax Sale Mechanics

  • What is sold: a tax certificate (lien) on the parcel; not the fee. Title passes only later by tax deed if unredeemed (SDCL 10-23-8, 10-25-11). [Source: sdlegislature.gov — SDCL 10-23-8]
  • Bidding method: bid-down interest. The treasurer offers each parcel and the best bid is the lowest rate of interest per year the bidder will accept; “no rate of interest higher than ten percent per year is a valid bid” (SDCL 10-23-8). Post-2006, in non-waiver counties the certificate is simply issued to the county rather than auctioned to investors (SDCL 10-23-28.1). [Source: sdlegislature.gov — SDCL 10-23-8, 10-23-28.1]
  • Interest / penalty: statutory maximum 10% per year on the certificate (the bid rate); the redemption amount carries that bid rate from the date of purchase, and subsequent taxes carry like interest from the date paid (SDCL 10-23-8, 10-24-1). Delinquent-tax interest/penalty is set under Title 10, Ch. 21 (SDCL 10-21-23, 10-21-25 referenced by county treasurers). [Source: sdlegislature.gov — SDCL 10-23-8, 10-24-1; Hutchinson County FAQ for Ch. 21 references]
  • Minimum bid composition: delinquent taxes + penalty + interest + costs (the certificate is offered for the full amount owed; bidders compete on interest rate, not price) (SDCL 10-23-8). [Source: sdlegislature.gov — SDCL 10-23-8]
  • Sale frequency / typical month: annual; tax-certificate sales are held by the county treasurer in connection with the annual delinquency cycle. Exact statutory sale date flagged for verification (county treasurers schedule the public sale).
  • Venue / platforms: county treasurer’s office (in person). South Dakota does not operate a centralized statewide online lien-auction platform; no vendor identified (most counties now simply take the certificate themselves under SDCL 10-23-28.1). [Source: sdlegislature.gov — SDCL 10-23-28.1]
  • Registration & deposit: set by the county treasurer; specific deposit rules flagged for verification (largely moot where the county is the certificate holder).
  • Subsequent taxes (“subs”): a tax-certificate holder may pay later years’ delinquent taxes; those amounts are added to the redemption amount with interest at the same bid rate from the date of payment (SDCL 10-24-1; cf. 10-23-21/-22 on certificate-holder tax payments). [Source: sdlegislature.gov — SDCL 10-24-1]

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

  • Pre-sale right: the owner may pay delinquent taxes at any time before the certificate sale; redemption is the operative post-sale right.
  • Post-sale period: three years from the date of the tax-certificate sale during which a deed cannot be sought (SDCL 10-25-1), plus the statutory back-end: even after three years, redemption does not expire until 60 days after the affidavit of completed service of the notice of intention to take tax deed is filed with the treasurer (SDCL 10-25-8). [Source: sdlegislature.gov — SDCL 10-25-1, 10-25-8]
  • Who may redeem: the owner of record, any person in possession, the person in whose name the property is taxed, and mortgagees / lienholders entitled to notice (SDCL 10-24-1, 10-25-3, 10-25-4). Heirs/personal representatives of a deceased owner may redeem (notice runs to them under SDCL 10-25-6). [Source: sdlegislature.gov — SDCL 10-24-1, 10-25-3, 10-25-6]
  • Amount formula: the sum stated in the tax certificate + interest at the bid rate from the date of purchase + subsequent taxes paid by the holder + like interest on those taxes from the date paid, plus statutory costs added before deed (SDCL 10-24-1, 10-25-9). [Source: sdlegislature.gov — SDCL 10-24-1, 10-25-9]
  • Premium to certificate holder: none beyond the bid interest rate (max 10%/yr); South Dakota bids down interest, so the holder earns only the rate it bid.
  • Procedure: the redemptioner pays the county treasurer, who records the redemption on the sales list, issues a receipt, files it with the county auditor, and holds the funds for the certificate holder (SDCL 10-24-1). [Source: sdlegislature.gov — SDCL 10-24-1]
  • Extinguishment: the right ends 60 days after the affidavit of completed service is filed if no redemption is made (SDCL 10-25-8); the treasurer then prepares and delivers the tax deed (SDCL 10-25-11), which is prima facie evidence of the regularity of all proceedings (SDCL 10-25-13). A defective/insufficient notice prevents valid issuance (see Module 6).
  • Special tolling: federal overlays apply — bankruptcy automatic stay and the SCRA can toll/postpone. See bankruptcy-automatic-stay, scra-protections. State-law tolling for minors/incompetents flagged for verification.

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

  • Belongs to: the prior owner of record (post-HB 1090). After the mandatory sale, surplus over the tax debt and costs is returned to the prior owner of record (SDCL 10-25-39). [Source: sdlegislature.gov — SDCL 10-25-39]
  • Claim waterfall (SDCL 10-25-39):
    1. County’s expenses of the tax-deed and sale proceedings;
    2. Taxes, penalty, interest, county liens and other costs, prorated on the most recent year’s tax levies until tax and interest are paid;
    3. Surplus to the prior owner of record;
    4. If the prior owner of record cannot be found within 180 days, surplus is transferred to the Unclaimed Property Division (ch. 43-41B). [Source: sdlegislature.gov — SDCL 10-25-39]
  • Filing venue: the county that conducted the tax-deed sale distributes the surplus (the statute is a return-to-owner mechanism, not an adversarial claim petition); thereafter, South Dakota Unclaimed Property (State Treasurer, cash.sd.gov) under ch. 43-41B. [Source: sdlegislature.gov — SDCL 10-25-39; cash.sd.gov]
  • Claim deadline: the county must locate/return to the prior owner within 180 days of the sale before escheating to Unclaimed Property; after transfer, the owner may reclaim through the Unclaimed Property program (generally no time bar to reclaim once held by the State) (SDCL 10-25-39; ch. 43-41B). [Source: sdlegislature.gov — SDCL 10-25-39]
  • Escheat: surplus unclaimed for 180 days → Unclaimed Property Division under the Revised Uniform Unclaimed Property Act (ch. 43-41B); reclaimable by the owner thereafter through the State program. [Source: sdlegislature.gov — SDCL 10-25-39, ch. 43-41B; cash.sd.gov]
  • Documentation required: proof of identity / prior-owner-of-record status to the county; for Unclaimed Property reclamation, a claim through cash.sd.gov. County- level documentation specifics flagged for verification.
  • Third-party recovery (governs whether a surplus-recovery agent may operate):
    • fee_cap_pct: null — no tax-deed-surplus-specific percentage cap located in Title 10. Once funds are with the State, agreements to recover unclaimed property are regulated under ch. 43-41B (the RUUPA “agreement to locate” / finder provisions). Exact SDCL 43-41B finder-fee cap and timing flagged for verification (RUUPA typically voids agreements made within 24 months of delivery and caps post-window fees, but the SD-enacted text was not directly pulled).
    • licensing_required: no surplus-recovery-specific license identified in Title 10; private-investigator/finder licensing not confirmed (flagged).
    • assignment_of_claim_allowed: the surplus runs to the “prior owner of record”; assignment of an unclaimed-property claim is governed by ch. 43-41B. [Flagged — statute text not directly pulled.]
    • cooling_off_period / contract_disclosure_rules / prohibited_practices: governed by ch. 43-41B’s agreement-to-locate provisions; specific SD text flagged for verification.
    • citation: SDCL 10-25-39 (surplus to owner); ch. 43-41B (unclaimed property).
  • Notice to former owner required? Yes — pre-deed notice of intention to take tax deed must be personally served on the owner/occupant/taxpayer and mailed to recorded mortgagees (SDCL 10-25-2 to 10-25-7); and post-sale the surplus is returned to the prior owner of record (SDCL 10-25-39). [Source: sdlegislature.gov — SDCL 10-25-5, 10-25-39]

▸ For Investors / Operators — A South Dakota tax-deed acquisition is now subject to a mandatory resale within one year (SDCL 10-25-39.1 county / 10-25-39.2 non-county), and the surplus over the tax debt and costs is returned to the prior owner of record (SDCL 10-25-39) — the deed is a pass-through to a public sale, not a windfall in the equity. Before committing capital, weigh the redemption risk (§2/2b — redemption runs until 60 days after the affidavit of completed service, and the redemption right is exercisable by “any person” before the deed issues), the path to marketable title (§5b — quiet title under ch. 21-41 plus the § 10-25-44 180-day bar), and which liens survive (§7b — Perry’s “subject to State claims,” the IRS § 7425 120-day redemption, and surviving governmental claims).

▸ For Former Owners — Since HB 1090 (2024), if a South Dakota tax deed property sells for more than the taxes, penalty, interest, county liens, and costs, the surplus is returned to the prior owner of record (SDCL 10-25-39). The county must locate and return it within 180 days before it transfers to the State Unclaimed Property Division (ch. 43-41B), where it remains reclaimable.

4. Mortgage Foreclosure

  • Process: both — judicial foreclosure (Title 21, Ch. 47) and non-judicial foreclosure by advertisement (Title 21, Ch. 48); a foreclosure-by- advertisement may be converted to judicial on demand. [Source: alllaw.com (Nolo) — citing SDCL 21-47, 21-48]
  • Timeline (foreclosure by advertisement):
    • Notice of sale served on the mortgagor at least 21 days before the sale (SDCL 21-48-6.1);
    • Publication of the notice once each week for four successive weeks (SDCL 21-48-6);
    • Sale at public auction. [Source: alllaw.com (Nolo) — citing SDCL 21-48-6, 21-48-6.1]
  • Reinstatement right:
    • Judicial: the borrower may reinstate before judgment (dismisses the action) or after judgment but before sale (postpones it) (SDCL 21-47-8, 21-47-10);
    • Non-judicial (advertisement): no statutory reinstatement right; depends on the mortgage’s contractual terms. [Source: alllaw.com (Nolo) — citing SDCL 21-47-8, 21-47-10]
  • Redemption after sale:
    • Standard: one year after the foreclosure sale (SDCL 21-52-11);
    • Short-term redemption mortgage: 180 days after the certificate of sale is recorded (SDCL 21-49-30, 21-52-11);
    • Abandoned property: court may reduce to 60 days (SDCL 21-49-13(8), 21-49-38). [Source: alllaw.com (Nolo) — citing SDCL 21-52-11, 21-49-30, 21-49-13]
  • Deficiency judgment: allowed, but with a fair-market-value offset.
    • Advertisement: if the mortgagee is the purchaser, it must show the property sold at true market value or more, and any deficiency is reduced by the difference between the sale price and true market value (SDCL 21-48-14);
    • Judicial: the court considers the property’s value and other factors (SDCL 21-47-16, 21-47-17). [Source: sdlegislature.gov — SDCL 21-48-14; alllaw.com (Nolo) — SDCL 21-47-16/-17]
  • Surplus distribution (foreclosure): sale proceeds pay the foreclosing debt, then junior lienors by priority, then the mortgagor (general rule under Title 21, Ch. 48). Exact surplus-distribution section flagged for verification.
  • Sale officer: sheriff (judicial); the foreclosing party / officer conducting the advertisement sale (Title 21, Ch. 48).

5. Sale Procedure Playbooks

Treasurer / tax-certificate & tax-deed procedure → see treasurer-sale

  1. Taxes go delinquent; the county treasurer offers a tax certificate per parcel at public sale, struck off at the lowest interest bid (max 10%/yr) (SDCL 10-23-8). In non-waiver counties (post-2006) the county takes the certificate (SDCL 10-23-28.1).
  2. A certificate holder may pay subsequent taxes, added to the redemption amount with like interest (SDCL 10-24-1).
  3. Owner (or other interested party) may redeem by paying the county treasurer the certificate amount + bid interest + subs + interest (SDCL 10-24-1).
  4. No deed sooner than 3 years and no later than 6 years from the certificate sale (SDCL 10-25-1).
  5. Holder serves the notice of intention to take tax deed — personal service on owner of record, person in possession, and the person taxed; publication (two successive weeks) for others; registered/certified mail to recorded mortgagees/lienholders (SDCL 10-25-2 to 10-25-7).
  6. Holder files an affidavit of completed service with the treasurer; redemption expires 60 days later (SDCL 10-25-8).
  7. Holder pays any prior outstanding tax certificates (SDCL 10-25-10); the treasurer prepares and delivers the tax deed (SDCL 10-25-11), which is prima facie evidence of regularity (SDCL 10-25-13).
  8. Mandatory resale (post-HB 1090): a county declares the property surplus and sells it within one year (auction under ch. 6-13 with 2-publication notice, or by broker) (SDCL 10-25-39.1); a non-county holder must sell at public auction within one year (SDCL 10-25-39.2). Surplus is returned to the prior owner of record (SDCL 10-25-39).
  9. Quiet title to clear the tax-deed title (SDCL 10-25-24; Title 21, Ch. 42).

Sheriff / mortgage foreclosure sale → see sheriff-sale

  1. Lender forecloses judicially (Title 21, Ch. 47) or by advertisement (Title 21, Ch. 48); advertisement requires 21-day mailed notice + 4-week publication (SDCL 21-48-6, 21-48-6.1).
  2. Public sale to the highest bidder; certificate of sale recorded.
  3. Redemption: one year (180 days short-term; 60 days if abandoned) (SDCL 21-52-11, 21-49-30, 21-49-13(8)).
  4. Deficiency with fair-value offset where the mortgagee buys (SDCL 21-48-14).
  • Notice requirements: tax deed — personal service on owner/occupant/taxpayer
    • publication 2 successive weeks + certified mail to mortgagees (SDCL 10-25-5), affidavit of service filed, 60-day redemption tail (SDCL 10-25-8); mortgage advertisement — 21-day mailed + 4-week published notice (SDCL 21-48-6/-6.1). [Source: sdlegislature.gov — SDCL 10-25-5, 10-25-8; alllaw.com — SDCL 21-48-6/-6.1]
  • Upset bid / confirmation: no North-Carolina-style upset bid for tax deeds; the post-deed surplus auction is a one-shot public sale (SDCL 10-25-39.1/.2). Judicial mortgage sales are subject to court confirmation.
  • Payment terms: auction deposit/balance per county notice; advertisement sale is cash to highest bidder.
  • Deed issued: tax deed — conveys title and possessory right (SDCL 10-25-12), prima facie evidence of regularity (SDCL 10-25-13), but no warranty; sheriff’s/officer’s deed on mortgage foreclosure. [Source: sdlegislature.gov — SDCL 10-25-12, 10-25-13]

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

  • Standard: South Dakota requires the statutory notice of intention to take tax deed to be given as prescribed before a treasurer may issue a deed; the notice/redemption procedure is the constitutional safeguard, aligning with mullane-v-central-hanover (“reasonably calculated”) and the actual-notice-to-record-mortgagees rule of mennonite-v-adams (SD requires certified/registered mail to recorded mortgagees, SDCL 10-25-5). A tax title taken without a valid proceeding is void and the owner may recover in equity on reimbursing the purchaser’s actual outlay plus interest (Coughlin v. City of Pierre). [Source: sdlegislature.gov — SDCL 10-25-5; vlex — Coughlin, 66 S.D. 523]
  • Required attempts: personal service on the owner of record, person in possession, and person taxed; publication (two successive weeks) for those not personally served; registered/certified mail, return receipt requested, to recorded mortgagees/lienholders (SDCL 10-25-5, 10-25-7); affidavit of completed service filed (SDCL 10-25-8). [Source: sdlegislature.gov — SDCL 10-25-5, 10-25-8]
  • Consequence of defective notice: a tax deed/title resting on an invalid proceeding is treated as void (Coughlin v. City of Pierre; statutory deed is only prima facie, not conclusive, evidence of regularity, SDCL 10-25-13). [Source: vlex — Coughlin, 66 S.D. 523; sdlegislature.gov — SDCL 10-25-13]
  • Leading cases: coughlin-v-city-of-pierre-1939, perry-v-state-department-of-social-security, tyler-v-hennepin-county, mennonite-v-adams, mullane-v-central-hanover, jones-v-flowers. (A modern (post-2000) SD Supreme Court decision squarely on tax-deed notice sufficiency was not located/verified — flagged in needs_verification.)

7. Title & Marketability

  • Deed warranty level: tax deed conveys no warranty; it vests title and a possessory right (SDCL 10-25-12) and is prima facie (not conclusive) evidence of regularity of all proceedings (SDCL 10-25-13). [Source: sdlegislature.gov — SDCL 10-25-12, 10-25-13]
  • Marketable immediately? No in practice — title is clouded until a quiet-title action (SDCL 10-25-24; Title 21, Ch. 42 “Actions to Quiet Tax Title”).
  • Quiet title required? Effectively yes for marketable/insurable title; the county may quiet title via the state’s attorney (SDCL 10-25-24, 10-25-25), and Title 21, Ch. 42 supplies the procedure for private holders. [Source: sdlegislature.gov — SDCL 10-25-24]
  • SOL to challenge deed: 180 days after the tax deed is recorded — no action to recover possession or to avoid the deed (and no defense in a quiet-title action) may be brought after that window (SDCL 10-25-44). [Source: sdlegislature.gov — SDCL 10-25-44]
  • Title insurance availability: generally only after quiet title; insurers typically will not insure a raw tax-deed title. [Industry practice — flagged.]
  • Common defects: insufficient/defective notice of intention or affidavit of service (SDCL 10-25-5, 10-25-8); failure to purchase prior outstanding certificates (SDCL 10-25-10); chain-of-title gaps; surplus not returned (post-HB 1090).

8. Case Law (real, verified)

CaseYearTopicHolding (plain English)Source
coughlin-v-city-of-pierre-19391939redemption, due_process, sale_procedureA void tax title gives the holder no more than a lien; a former owner seeking equity to set it aside need only reimburse the purchaser’s actual purchase price plus statutory interest, not the full delinquent tax (66 S.D. 523, 286 N.W. 877).https://case-law.vlex.com/vid/coughlin-v-city-of-929880883
perry-v-state-department-of-social-security1946sale_procedure, titleA tax deed vests an estate in fee simple subject to claims the State holds for taxes, liens, or encumbrances (here, old-age-assistance/social-security liens survived the tax deed) (71 S.D. 247, 23 N.W.2d 279).https://www.courtlistener.com/opinion/4126332/perry-v-state-department-of-social-security/
tyler-v-hennepin-county2023surplus, due_processGovernment may not keep surplus equity beyond the tax debt; retention is an unconstitutional taking (598 U.S. 631). South Dakota’s HB 1090 (2024) surplus-return reform (SDCL 10-25-39/.1/.2) was enacted to comply.https://www.supremecourt.gov/opinions/22pdf/22-166_8n59.pdf

Note: Heikkila v. Carver (1985) and Spitzer v. Spitzer (1969) surfaced in searches but are a contract-for-deed decision and an intestacy/deed-delivery decision (tax-sale redemption only tangential), respectively; they are excluded from the authority table to avoid mischaracterization (see needs_verification).

9. Edge Cases (state-specific notes)

  • bankruptcy-automatic-stay — A Chapter 13 filing stays the tax-deed proceeding and can cure delinquent taxes through a plan; the SDCL 10-25-1/-8 periods are tolled by the federal automatic stay (state statute is silent).
  • federal-tax-lien-redemption — The IRS holds a 120-day redemption right after a sale that discharges a federal tax lien (26 U.S.C. § 7425) — federal overlay in SD.
  • state-lien-survival — Per Perry, a South Dakota tax deed takes subject to claims of the State for taxes/liens; not all senior governmental claims are wiped.
  • heirs-property — Heirs and a decedent’s personal representative are entitled to notice and may redeem (SDCL 10-25-6); notice runs to all record interests.
  • scra-protections — The Servicemembers Civil Relief Act may toll redemption / postpone sale for active-duty members (federal overlay).
  • surplus-funds — Post-HB 1090, tax-deed surplus belongs to the prior owner of record; mortgage-foreclosure surplus follows lien priority then the mortgagor.
  • Manufactured homes — taxed as real or personal property depending on affixation; flagged for verification of the certificate mechanism for unaffixed homes.
  • Void vs. voidable — a tax title from an invalid proceeding is treated as void (Coughlin); the statutory deed is only prima facie evidence (SDCL 10-25-13). See void-vs-voidable.

10. Operations

2b. Redemption Advanced

Assignability of the statutory redemption right:

  • Who holds the right: SDCL 10-24-1 provides that “any person may redeem a tax certificate on real property sold for taxes at any time before issue of a tax deed for the property.” (SDCL 10-24-1, retrieved 2026-06-02) The class is therefore not limited to the owner, heirs, or mortgagees — the statute names no restriction on who may redeem.
  • Is the right assignable? Functionally, yes. Because “any person” may redeem before the deed issues, a third party who takes an assignment of the owner’s interest (e.g., a quitclaim deed) or who is a mortgagee/lienholder of the owner may redeem in its own right. There is no SDCL provision prohibiting a stranger-investor from taking a conveyance from the owner solely to acquire standing to redeem. needs_verification — no retrieved SD appellate decision squarely holding that the redemption right is or is not freely assignable as a standalone asset independent of an underlying interest.
  • Purchase mechanism: a deed of conveyance from the owner (the assignee then redeems under § 10-24-1 as a “person”), or redemption by a mortgagee/lienholder in its own right. No court approval is required. On return of the certificate for cancellation, the redemption operates as a release of all claims described in the certificate (SDCL 10-24-2). (SDCL 10-24-2, retrieved 2026-06-02)
  • Restrictions: none in § 10-24-1 (no natural-persons-only or heirs/mortgagees-only limitation).

Equitable vs. statutory redemption:

  • South Dakota’s tax-sale redemption is statutory (SDCL ch. 10-24), running until the tax deed issues — i.e., until 60 days after the affidavit of completed service is filed (SDCL 10-25-8). There is no separate post-deed equitable redemption for tax sales; once the period expires unredeemed and the treasurer delivers the deed (SDCL 10-25-11), the former owner’s remedy shifts to a surplus claim (§3) or a void-deed challenge (§6), not equitable redemption.
  • A distinct equitable remedy survives only where the tax title is void for a defective proceeding: the former owner may set the title aside in equity on reimbursing the purchaser’s actual outlay plus interest (Coughlin v. City of Pierre). That is a void-title remedy, not a redemption right.
  • Available pre-deed only: statutory redemption terminates at deed issuance (SDCL 10-25-8, 10-25-11).

Installment redemption:

  • Chapter 10-24 contemplates redemption by payment of the certificate sum + interest + subsequent taxes + like interest (SDCL 10-24-1); no statutory installment-payment plan to redeem a tax-sale certificate over time was located. needs_verification — no SD primary source retrieved authorizing partial/installment redemption.

Assignment of the tax certificate (purchaser side) mid-redemption:

  • A tax certificate is assignable. SDCL 10-23-22 expressly refers to “the purchaser or assignee” of a tax certificate and provides that the assignee “shall have the same lien for the taxes paid subsequently and may add the taxes to the amount paid under the original tax certificate,” with the treasurer recording the payer, date, amount, and tax year on the certificate record. (SDCL 10-23-22, retrieved 2026-06-02) The assignee steps into the holder’s position for redemption proceeds and for the eventual tax deed.
  • Practical note: post-2006, in non-waiver counties the county is the default certificate holder (SDCL 10-23-28.1), so private certificate assignment most often arises where a county has waived the bar or assigns a county-held certificate. exact county-held-certificate assignment authority flagged for verification.

3b. Surplus Advanced

Claim assignability — tax-deed surplus (SDCL 10-25-39):

  • Full assignment permitted? SDCL 10-25-39 directs that the surplus “must be returned to the prior owner of record,” and chapter 10-25 imposes no fee cap, licensing requirement, cooling-off period, or disclosure regime on assignments of the surplus while the county holds it. (SDCL 10-25-39, retrieved 2026-06-02) The statute is a return-to-owner mechanism rather than an adversarial claim petition; whether the owner may outright assign (sell) the surplus claim, versus only authorize a fee-for-service recovery, is not addressed by the statute’s text. needs_verification — no retrieved SD authority squarely holding a tax-deed surplus claim is freely assignable or capping such an assignment.
  • Assignment vs. fee agreement: chapter 10-25 regulates neither the level nor the form of a recovery agreement. Once funds escheat to the State Unclaimed Property Division (180 days, ch. 43-41B), the assignment/finder regime shifts to the Revised Uniform Unclaimed Property Act. The SD-enacted ch. 43-41B “agreement to locate” / finder-fee cap, cooling-off window, and disclosure rules were not directly retrieved and are flagged for verification (RUUPA model text commonly voids agreements made within 24 months of delivery and caps post-window fees, but the SD text was not pulled).
  • Fee cap applies to assignments? No cap found in chapter 10-25. Post-escheat, ch. 43-41B governs — needs_verification of the SD-enacted finder-fee cap.

Statute of limitations on the surplus claim:

  • Period / trigger: the county must locate and return the surplus to the prior owner of record; if the owner cannot be located within 180 days, the surplus transfers to the Unclaimed Property Division under ch. 43-41B. (SDCL 10-25-39, retrieved 2026-06-02) The 180-day clock runs from the tax-deed sale / surplus realization; after transfer, the owner may reclaim from the State (RUUPA generally imposes no outer bar on reclamation once the State holds the funds — exact ch. 43-41B reclamation period flagged for verification).
  • This is the only surplus-specific limitation in chapter 10-25; there is no separate “claim petition” deadline of the South-Carolina/Florida type because the return is affirmative (county-driven), not claimant-driven.

Competing claimant procedure:

  • Filing race? No statutory first-to-file race in chapter 10-25 — the surplus runs to the prior owner of record after the waterfall (county expenses → taxes, penalty, interest, county liens, costs → surplus to prior owner) (SDCL 10-25-39). Whether junior lienholders of the former owner can claim the tax-deed surplus ahead of the prior owner, or whether the county must interplead competing claims, is not resolved by the statute’s text. needs_verification — chapter 10-25 does not prescribe an interpleader procedure for competing tax-deed-surplus claimants; this is a genuine open question (see open_questions).

Deceased-owner procedure:

  • The surplus belongs to “the prior owner of record.” Where that owner is deceased, the estate is entitled; the notice statute already routes pre-deed notice to the decedent’s personal representative (foreign or resident) or, if none is known, to known heirs and beneficiaries (and to “unknown personal representatives, heirs, and beneficiaries” by publication) (SDCL 10-25-6). (SDCL 10-25-6, retrieved 2026-06-02) By parity, a personal representative with letters has standing to claim or assign the surplus; absent an open estate, heirs typically must open probate (or a small-estate procedure) to establish entitlement. needs_verification — whether a SD county accepts a direct-heir surplus claim without probate letters where ownership is unambiguous; SD small-estate threshold (Title 29A probate code).

Fraudulent-conveyance / fraudulent-transfer exposure:

  • An assignment of the surplus (or of the underlying redemption right) by an insolvent owner for less than reasonably equivalent value is exposed to a creditor challenge under South Dakota’s Uniform Fraudulent Transfer Act, SDCL chapter 54-8A (“This chapter may be cited as the Uniform Fraudulent Transfer Act,” SDCL 54-8A-12). (SDCL 54-8A-12, retrieved 2026-06-02)
  • SOL: SDCL 54-8A-9 extinguishes the claim unless brought within four years after the transfer (or, for actual-intent claims, within one year after the transfer was or could reasonably have been discovered, if later); insider-preference claims under § 54-8A-5(b) carry a one-year period. (SDCL 54-8A-9, retrieved 2026-06-02) A good-faith transferee who took for reasonably equivalent value is protected (the UFTA safe harbor).

Surplus-claimant notice:

  • The surplus-return mechanism is county-driven: the county must attempt to locate and return the surplus to the prior owner of record, escheating to Unclaimed Property only if the owner cannot be found within 180 days (SDCL 10-25-39). Chapter 10-25 does not separately require the county to notify junior lienholders of an available surplus. needs_verification — whether any SD authority requires affirmative lienholder notice of a tax-deed surplus.

5b. Title Advanced

Quiet title — when required vs. optional:

  • Practical standard: a South Dakota tax deed is prima facie (not conclusive) evidence of the regularity of all proceedings (SDCL 10-25-13) and carries no warranty; it does not, by itself, convey marketable or insurable title. Title insurers generally will not insure a raw tax-deed title until a quiet-title action clears it and/or the § 10-25-44 challenge window has run.
  • Statutory cutoff investors rely on: SDCL 10-25-44 bars any action by the former owner (or one claiming under the owner) to recover possession or to avoid the deed unless commenced within 180 days after the recording of the deed, and bars defenses in a quiet-title action by the grantee unless interposed within that same 180 days. (SDCL 10-25-44, retrieved 2026-06-02)
  • Caveat — void deeds: a tax title resting on a fundamentally defective proceeding is treated as void (Coughlin v. City of Pierre), and the statutory deed is only prima facie evidence (SDCL 10-25-13); a jurisdictional notice defect can survive the short curative window in the strongest cases. needs_verification — interaction of the 180-day § 10-25-44 bar with a void-for-notice defect, post-2000 SD case.
  • Judicial confirmation before deed issues? No. The Chapter 10-25 tax deed is administrative — the treasurer delivers the deed after the notice/affidavit procedure without court confirmation (SDCL 10-25-8, 10-25-11). Quiet title, if pursued, is a separate post-deed action.

Action type and court:

  • Quiet title is a judicial action in circuit court in the county where the property lies. A county that takes a tax deed may quiet title via the state’s attorney (SDCL 10-25-24), and the action is conducted under SDCL chapter 21-41 (actions to quiet title), with the county exempted from the publication-defendant indemnity-bond requirement (SDCL 10-25-25). (SDCL 10-25-24; SDCL 10-25-25, retrieved 2026-06-02) A private tax-deed holder proceeds under ch. 21-41’s general quiet-title procedure.
  • Timeline / cost: an uncontested quiet title in circuit court is commonly concluded in several months (longer with service by publication on unknown heirs); cost is typically a few thousand dollars (attorney fee + filing + abstract + publication). needs_verification — precise SD timeline/cost ranges are practitioner estimates, not statutory.

Marketable Title Act:

  • South Dakota has a Marketable Title Act — SDCL chapter 43-30 (“Marketable Title to Real Estate”). A record title holder with an unbroken chain through a conveyance recorded 22 years or more and in possession holds marketable record title, free of older clouds (with an affidavit-of-possession mechanism, SDCL 43-30-7). (SDCL ch. 43-30, retrieved 2026-06-02) The Act does not substitute for a quiet title in the tax-deed context (the deed is typically recent), but can clear older pre-deed clouds on a well-seasoned chain. exact 43-30 section numbers / 22-year period flagged for direct verification (chapter index retrieved via search).

Deed seasoning — title-insurer requirements:

  • Insurers typically require the tax deed to be seasoned — the redemption/notice procedure complete and the § 10-25-44 180-day challenge window run — and often a quiet-title action, before underwriting; the deed carries no warranty, so it is insured (if at all) on the strength of curative work. needs_verification — specific named-insurer seasoning guidelines (market practice, not statute).

Chain-of-title cure depth:

  • A ch. 21-41 quiet-title judgment cures clouds from all pre-deed adverse claims properly joined and served. The tax deed itself does not by its own force clear a federal tax lien where the United States was not § 7425-noticed (§7b), nor does it cut off claims the State holds for taxes/liens (Perry).

5c. TRO & Injunctive Relief

Recognized grounds to halt a sale:

  1. Notice / due-process defect — failure of the SDCL 10-25-2 to 10-25-7 service / publication / certified-mail chain not “reasonably calculated” to reach the owner (Mullane; Jones v. Flowers; Mennonite).
  2. Payment / redemption dispute — a timely tender of redemption refused or misapplied (SDCL 10-24-1).
  3. Constitutional — taking-without-just-compensation / Fifth Amendment (Tyler-type), though SD now returns the surplus.
  4. SCRA — active-duty servicemember protections (federal overlay).
  5. Bankruptcy automatic stay — a sale in violation of 11 U.S.C. § 362 (a stay violation that halts the proceeding; see bankruptcy-automatic-stay).
  6. Fraud / irregularity in the proceeding.

Legal standard:

  • South Dakota’s injunction practice is governed by SDCL 15-6-65 (the state analog to Federal Rule 65). For a temporary restraining order without notice, § 15-6-65(b) requires that “it clearly appears from specific facts shown by affidavit or by the verified complaint that immediate and irreparable injury, loss, or damage will result to the applicant before the adverse party or his attorney can be heard in opposition,” and that the applicant’s attorney certify in writing the efforts made to give notice or the reasons notice should not be required. (SDCL 15-6-65(b), retrieved 2026-06-02) A TRO without notice expires by its terms within a court-set period not to exceed ten days unless extended.
  • The substantive preliminary-injunction inquiry (likelihood of success, irreparable harm, balance of equities, public interest) tracks the general equity standard. needs_verification — a retrieved controlling SD opinion stating the precise multi-factor PI test verbatim.

Court with jurisdiction:

  • The circuit court in the county where the property lies. Because the tax deed is administrative (no pending case), a movant must file a separate emergency action in circuit court before the deed issues / the surplus sale occurs. For a judicial mortgage foreclosure (Title 21, Ch. 47), relief is sought in the pending action.

Bond requirement:

  • Required. SDCL 15-6-65(c) directs that “the court shall require a written undertaking on the part of the applicant with or without sureties in such sum as the court deems proper” for costs and damages if the party is wrongfully enjoined; the State and its officers/agencies are exempt. (SDCL 15-6-65(c), retrieved 2026-06-02) The dollar amount is set by the court.

Emergency timeline:

  • An ex parte TRO meeting the § 15-6-65(b) affidavit/verified-complaint showing can be obtained on an emergency basis (often within 24–48 hours at the court’s discretion), followed by an expedited preliminary-injunction hearing; the TRO itself lasts no more than ten days without extension. needs_verification — any fixed SD deadline for the follow-on PI hearing.

Effect on a completed sale:

  • A non-judicial tax deed is harder to undo after delivery: the deed is prima facie evidence of regularity (SDCL 10-25-13) and the § 10-25-44 180-day bar cuts off most challenges. A void (fundamentally defective) proceeding can still be set aside in equity (Coughlin), but a routine irregularity cannot after the curative window. For a judicial mortgage foreclosure, relief is sought in the pending case before confirmation. needs_verification — a retrieved SD holding on the effect of a post-deed TRO/injunction on a completed tax-deed sale.

Non-judicial notes:

  • Tax-deed issuance is administrative, so there is no pending case in which to move — a separate emergency circuit-court action is required, which compresses the practical window for relief relative to a judicial foreclosure.

Leading cases: coughlin-v-city-of-pierre-1939 (void-title equity), jones-v-flowers (due-process standard).

7b. Lien Survival & Purchaser Exposure

IRS 120-day redemption (26 U.S.C. § 7425):

  • Applies. Where a federal tax lien is recorded junior to the tax lien being enforced, the United States must be given notice of a non-judicial sale not less than 25 days before the sale; if properly noticed, the federal lien is discharged but the IRS holds a 120-day post-sale right of redemption (or the local-law redemption period, whichever is longer) under § 7425(d); if not noticed, the federal lien survives the sale. (26 U.S.C. § 7425, retrieved 2026-06-02)
  • Procedure / exposure: on redemption the IRS pays the purchaser the price paid plus interest and certain costs and records a certificate of redemption (per 28 U.S.C. § 2410(d)). A federal-tax-lien search before taking a SD tax deed is essential — an un-noticed federal lien is a common way a buyer takes subject to a surviving senior federal claim. See federal-tax-lien-redemption.

HOA / condominium super-priority:

  • South Dakota is NOT a super-priority / super-lien state for HOA or condominium assessments. South Dakota’s condominium statute (SDCL chapter 43-15A) is principally a developer-registration/disclosure act and does not create a statutory common-expense assessment lien with priority over a first mortgage; an association’s lien arises from its recorded covenants and is enforced judicially, junior to a first mortgage. A senior mortgage foreclosure that joins the association extinguishes the subordinate assessment lien, with no super-priority “safe harbor” payment imposed on the foreclosing lender. [Source: SDCL ch. 43-15A index (sdlegislature.gov); corroborated by multiple SD HOA-law summaries — needs_verification of the exact chapter-43-15A section, if any, addressing assessment-lien priority; SD appears to have no super-lien statute.]
  • Survives a tax sale? A South Dakota tax deed (enforcing the ad valorem tax lien) is senior to a private HOA/condominium assessment lien; the assessment lien does not survive ahead of the tax title. needs_verification — no retrieved SD appellate decision squarely holding an HOA/condo assessment lien is extinguished by a Chapter 10-25 tax deed (the tax-lien-priority and no-super-lien rules support it, but a case is not retrieved).

Environmental / CERCLA liens:

  • A federal CERCLA lien (42 U.S.C. § 9607(l)) is a federal claim; as with a federal tax lien, the United States’ notice rights govern whether it is discharged by the sale. CERCLA owner/operator liability runs with the land regardless of how title was acquired, so a tax-deed purchaser of a contaminated site can face cleanup liability independent of the recorded lien. needs_verification — no SD-specific authority retrieved on CERCLA-lien survival of a Chapter 10-25 tax deed; this reflects the general federal rule.
  • State: no confirmed South Dakota environmental super-lien with priority over a tax title was located. needs_verification.

Municipal code liens:

  • The surplus waterfall pays “county liens and other costs” ahead of the prior owner (SDCL 10-25-39), indicating governmental/county claims are paid from the proceeds. Per Perry v. State Dep’t of Social Security, a SD tax deed takes subject to claims the State holds for taxes, liens, or encumbrances — so not all senior governmental claims are wiped. Whether a municipal code-enforcement / nuisance-abatement lien survives a Chapter 10-25 tax deed is not resolved by retrieved primary authority. needs_verification.

Mechanic’s liens:

  • A mechanic’s/materialman’s lien (SDCL ch. 44-9) is a private statutory lien; its priority against a tax title turns on recording dates and the superiority of the ad valorem tax lien. needs_verification — no retrieved SD authority squarely on whether a perfected mechanic’s lien survives a Chapter 10-25 tax deed.

Junior-mortgage exposure:

  • A SD tax sale enforces the ad valorem tax lien, generally superior to private mortgages; a properly conducted tax deed conveys free of junior and senior private mortgages provided required notice (including certified/registered mail to recorded mortgagees, SDCL 10-25-3, 10-25-5) was given. Common mistake: assuming the deed wipes everything — it does not clear a federal tax lien where the U.S. was not § 7425-noticed, and a failure to notice a recorded mortgagee can render the proceeding defective/void (Coughlin; SDCL 10-25-3).

Due-diligence checklist (SD tax-deed buyer):

  1. Federal tax lien search (county lien index / IRS) — § 7425 notice / 120-day redemption exposure.
  2. Recorded-mortgagee check — confirm SDCL 10-25-3/10-25-5 certified-mail notice was given (failure may void the proceeding).
  3. Title / notice-chain review — service, publication, affidavit of completed service (SDCL 10-25-8); was a prior outstanding certificate paid (SDCL 10-25-10)?
  4. State-claim check — Perry: tax deed takes subject to claims the State holds for taxes/liens.
  5. County-lien / code-lien search — county liens are paid ahead of the owner from the surplus; municipal code-lien survival unresolved.
  6. HOA / condo status — junior to the tax lien, but confirm any separately recorded interests.
  7. Bankruptcy search on the owner — active stay at the time of sale?
  8. Probate / heirs check — decedent owners trigger SDCL 10-25-6 notice; unprobated estates are a frequent quiet-title source.
  9. Environmental check — CERCLA / contaminated-site liability runs with the land.
  10. SCRA servicemember check on the owner.
  11. Mandatory-resale awareness — a non-county tax-deed holder must itself resell at public auction within one year (SDCL 10-25-39.2) and return surplus (SDCL 10-25-39).

10b. Purchaser Obligations During the Redemption Period

Subsequent taxes:

  • A tax-certificate holder (or assignee) may pay later years’ delinquent taxes, which are added to the redemption amount with interest at the bid rate from the date paid; the purchaser/assignee “shall have the same lien for the taxes paid subsequently and may add the taxes to the amount paid under the original tax certificate” (SDCL 10-23-22; SDCL 10-24-1). (SDCL 10-23-22, retrieved 2026-06-02) Paying subs preserves the holder’s full reimbursement on redemption; it is permissive, not mandatory.

Owner-expiration notice:

  • The certificate holder (not a court) drives the pre-deed notice: it serves the notice of intention to take tax deed on the owner of record, the person in possession, the person taxed, recorded mortgagees/lienholders, and (for deceased owners) the personal representative or heirs (SDCL 10-25-2 to 10-25-7), then files an affidavit of completed service; redemption does not expire until 60 days after that affidavit is filed (SDCL 10-25-8). (SDCL 10-25-3, retrieved 2026-06-02) Consequence of defective notice: the proceeding is invalid and the resulting title is treated as void (Coughlin; SDCL 10-25-13 deed is only prima facie evidence).

Owner occupancy:

  • During the redemption period the certificate holder holds a lien, not a possessory right; the owner retains possession until the tax deed issues. The deed conveys title and the possessory right to the grantee (SDCL 10-25-12). The certificate holder may not enter or take possession before the deed issues.

Costs collectible on redemption:

  • The redemption amount is the sum listed in the tax certificate + interest at the bid rate from the date of purchase + subsequent taxes paid + like interest on those taxes from the date paid (SDCL 10-24-1), plus statutory costs added before the deed (SDCL 10-25-9, 10-25-11). (SDCL 10-24-1, retrieved 2026-06-02) Improvements are not collectible — the holder has no possession or right to improve during the period. The statutory redemption fee on a privately held certificate is capped at $50 (SDCL 10-23-8), deducted from the holder’s proceeds.

Maintenance obligation:

  • None on the certificate holder during the redemption period — it holds a lien only, with no possession and no statutory maintenance duty; the owner, who retains possession, remains responsible. After the deed issues, the grantee has the ordinary obligations of an owner under local code. needs_verification — no SD statute imposing a tax-certificate-holder maintenance duty during redemption (consistent with the no-possession rule).

11b. Restrictions & Special Rules

Entity / insider restrictions:

  • Entity eligibility: SDCL 10-24-1 (“any person may redeem”) and the tax-sale chapter use broad language; no natural-persons-only restriction on holding a tax certificate or acquiring a tax deed was located. LLCs, corporations, and trusts may hold tax-sale interests. needs_verification of any SD entity-eligibility limitation in ch. 10-23.
  • Foreign / alien ownership — agricultural land: SDCL chapter 43-2A caps foreign ownership of agricultural land at 160 acres (with exceptions for inheritance and for land held as security for debt). (SDCL 43-2A-2, retrieved 2026-06-02) Critically for tax-deed buyers, SDCL 43-2A-4 exempts “agricultural lands acquired by process of law in the collection of debts, or by any procedure for the enforcement of a lien or claim thereon,” but requires disposal within three years of acquiring title. (SDCL 43-2A-4, retrieved 2026-06-02) A foreign acquirer of ag land via a tax certificate/deed therefore falls within the lien-enforcement exception but is subject to the 3-year divestiture. (Post-2024 amendments add tighter limits on “prohibited entities” from designated countries — exact current text flagged for verification.)
  • Insider prohibition: chapter 10-23/10-25 contains no express prohibition on county treasurers/auditors/employees bidding for their own account; general SD governmental-ethics law may restrict officials from profiting from official duties. needs_verification — confirm no chapter-10 or ethics-opinion bar specific to tax-sale bidding by officials.

Right of first refusal / land bank:

  • South Dakota has no separate statewide land-bank enabling act of the Ohio/Georgia type. Instead, the county is the default certificate holder (post-2006, SDCL 10-23-28.1) for most parcels, and after taking a tax deed a county must declare the property surplus and sell it within one year (auction under ch. 6-13 or by broker) (SDCL 10-25-39.1) — the county effectively functions as a temporary holder/disposer rather than a permanent land bank. A non-county tax-deed holder must likewise resell at public auction within one year (SDCL 10-25-39.2). needs_verification — any SD local land-bank authority or municipal ROFR.

Deficiency judgment (mortgage foreclosure):

  • Permitted, with a fair-value mechanism. In foreclosure by advertisement, if the mortgagee is the purchaser and seeks a deficiency, it must establish that the property “sold at foreclosure sale for its true market value or more,” and the court deducts from any deficiency “the difference between the true market value … at the time of such sale and the amount for which it sold” if the sale price was below true market value (SDCL 21-48-14). (SDCL 21-48-14, retrieved 2026-06-02)
  • In judicial foreclosure, a deficiency is available only on application to the court in which the judgment was rendered (SDCL 21-47-16); and SDCL 21-47-17 provides that, except as provided by § 21-47-16, a judicial foreclosure “operates as a complete extinguishment, satisfaction and payment of the debt secured by the mortgage.” (SDCL 21-47-16; SDCL 21-47-17, retrieved 2026-06-02) The deficiency is thus a court-controlled exception to default extinguishment.
  • After a tax sale: no deficiency judgment — the Chapter 10-25 tax-deed process collects only what the property brings (and now returns surplus); the tax debt is not pursued against the former owner personally.

Anti-deficiency statute:

  • South Dakota has no general anti-deficiency statute barring deficiency judgments; instead the fair-market-value offset (SDCL 21-48-14 for advertisement; the court’s § 21-47-16 control in judicial foreclosure) caps the deficiency at the debt minus the property’s true market value. No purchase-money-only anti-deficiency bar of the western-state type was located. needs_verification.

One-action rule:

  • SDCL 21-47-17’s default rule — that a judicial foreclosure extinguishes the debt except where a deficiency is sought by court application under § 21-47-16 — operates functionally to channel the mortgagee into the foreclosure action (no free-standing later suit on the note once foreclosed), but South Dakota has no one-action rule of the California type requiring the creditor to exhaust the security before any action. needs_verification — confirm against a retrieved SD primary source that no California-style one-action rule applies; the § 21-47-17 extinguishment is the closest analog.

Who this page is for

▸ For Investors / Operators — Start with §1 (bid-down-interest certificate, 10% max, and that post-2006 the county is the default holder unless it waives the bar), §2/2b (redemption runs until 60 days after the affidavit of completed service; “any person” may redeem before the deed; the certificate is assignable under § 10-23-22), §5b (path to marketable title — quiet title under ch. 21-41 plus the § 10-25-44 180-day bar and the ch. 43-30 Marketable Title Act), §7b (liens that survive — federal tax liens if the U.S. was not § 7425-noticed, Perry’s “subject to State claims,” and the IRS 120-day redemption), and §11b (broad entity eligibility, the ch. 43-2A foreign-ag-land 3-year divestiture for lien-enforcement acquisitions, and the mandatory one-year resale of a tax-deed under § 10-25-39.1/.2).

▸ For Former Owners — Start with §3 (surplus — since HB 1090 (2024), any sale price above taxes, penalty, interest, county liens, and costs is returned to the prior owner of record under § 10-25-39; the county must locate and return it within 180 days before it transfers to the State Unclaimed Property Division), §2 (redemption — paying the certificate sum plus bid interest and subs to the county treasurer before the deed issues), and §5c (grounds, the § 15-6-65 bond, and procedure for an emergency circuit-court motion to halt a sale).
