How surplus escheats here

See escheat-and-unclaimed-property for the custodial-taking framework and iowa for the controlling tax-sale and surplus statutes. Where foreclosure-sale surplus is remitted to the Treasurer rather than held at the county or in a court registry, the taking is custodial and reclaimable.

Dormancy period: Under Iowa’s Disposition of Unclaimed Property Act (Iowa Code ch. 556) the general dormancy period is commonly stated as three years; the precise period for sale-surplus / court-held funds is needs_verification against the current statute. Do not rely on a single figure here.

Claiming

1. Search by name at greatiowatreasurehunt.gov.
2. Select matching property and begin the claim.
3. Provide proof of identity and ownership; documentation scales with amount and type; heirs supply estate paperwork.
4. The Treasurer reviews and pays approved claims; claims line (515) 281-5367. Free to file. (Source: https://www.greatiowatreasurehunt.gov/ , retrieved 2026-06-02.)

▸ For Investors / Operators. Treasure Hunt escheat is a downstream money event that does not cloud acquired title or revive redemption. Confirm in iowa Module 3 whether surplus is held by the county / court or remitted to the Treasurer before modeling any surplus-linked strategy.

▸ For Former Owners. If your Iowa property was sold and surplus may exist, search the Great Iowa Treasure Hunt for free at greatiowatreasurehunt.gov. Filing is free; once funds are in Treasurer custody the claim is not time-barred. Also check the county / court registry where the sale occurred.
