State Unclaimed Property in South Dakota

The South Dakota State Treasurer is the administrator for unclaimed property — dormant bank accounts, uncashed checks, insurance payouts, and similar assets — under the Uniform Unclaimed Property Act. The property is held until the owner or their heirs claim it; heirs of a deceased owner file a verified claim with proof of death and authority to act for the estate.

State Unclaimed Property in South Dakota: key facts

Administering office
South Dakota State Treasurer, Unclaimed Property Division; the State Treasurer is the statutory administrator (SDCL 43-41B-1).
Official search
cash.sd.gov, the State Treasurer's official portal, which searches and files claims through southdakota.findyourunclaimedproperty.com (free).
Heir claim documents
A claim form prescribed by the administrator and verified (signed) by the claimant, with a copy of a photo ID and a Social Security number. The claim states your relationship to the owner — owner, heir, or representative — and any further requirements are listed on the form the portal generates for you (SDCL 43-41B-25).
Proving a right to claim for a deceased owner
Submit the court order documents showing appointment as personal representative or executor — the will, court appointment, or probate. If the deceased left no will, an affidavit of small estate may be submitted when the SDCL 29A-3-1201 requirements are met. A certified death certificate is requested from the South Dakota Department of Health vital records office.
Decision window
The administrator considers each filed claim within 180 days and gives notice if the claim is denied in whole or in part (SDCL 43-41B-25).
Small estate option
Heirs may avoid full probate by using the SDCL 29A-3-1201 successor affidavit when the entire estate, less liens and encumbrances, does not exceed $100,000, at least 30 days have passed since death, no personal representative has been appointed or applied for, and the decedent incurred no indebtedness to the Department of Social Services for medical assistance for nursing home or other medical institutional care. The affidavit covers personal property, bank accounts, securities, and similar assets. Present it to any holder — including unclaimed property — who must then transfer the property to the successor.

Governing law: SDCL Chapter 43-41B (Uniform Unclaimed Property Act); §§ 43-41B-1, 43-41B-25

Steps to take when someone dies

  1. Search cash.sd.gov (the State Treasurer's portal, which searches southdakota.findyourunclaimedproperty.com) for the deceased's name and prior addresses, and run a multi-state search at missingmoney.com.
  2. Start the claim, giving your mailing address and your relationship to the owner — heir or estate representative. The portal then generates the claim form, which requires:
    • The completed, signed (verified) claim form
    • A copy of your photo ID and your Social Security number
    • Any further documents the generated form lists for your relationship and property type
  3. Email or mail the signed claim package to the Unclaimed Property Division; track the claim online with the claim number you were given.
  4. The administrator reviews the claim and provides notice within 180 days if it is denied in whole or in part (SDCL 43-41B-25).

Frequently asked questions

Search cash.sd.gov for the deceased's name, then start the claim as an heir or estate representative. Each claim requires a completed, signed claim form, a copy of a photo ID, and a Social Security number; any other requirements for your claim are listed on the form the portal generates. To prove your right to claim for a deceased person, submit the court order documents showing your appointment as personal representative or executor — the will, court appointment, or probate — or, if the deceased left no will, an affidavit of small estate meeting the SDCL 29A-3-1201 requirements. Questions go to the Unclaimed Property Division at 605-773-3379 or unclaimed@sdtreasurer.gov.

Under SDCL 43-41B-25, the administrator considers each filed claim within 180 days and provides notice to the claimant if the claim is denied in whole or in part.

No. The State Treasurer's portal states that "the State holds these lost funds until claimed by either the original owner or their heirs," so there is no deadline for an heir to file a claim.

Yes. Under SDCL 29A-3-1201, a successor may present an affidavit to any holder of the decedent's personal property — including the State Treasurer as unclaimed property administrator — when the value of the entire estate (less liens and encumbrances) does not exceed $100,000, thirty days have elapsed since the death, no application or petition for appointment of a personal representative is pending or has been granted, and the decedent incurred no indebtedness to the Department of Social Services for medical assistance for nursing home or other medical institutional care. The holder must then transfer the property to the successor without requiring a court order.
