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.

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).

Required Documents

  • Completed, signed claim form: On the form prescribed by the administrator and verified by the claimant; the form the portal generates lists any other requirements.
  • Copy of a photo ID
  • Social Security number
  • Court order documents showing appointment as personal representative or executor: The will, court appointment, or probate.
  • Affidavit of small estate: if the deceased did not have a will and the SDCL 29A-3-1201 requirements are met
  • Certified death certificate: Requested from the South Dakota Department of Health vital records office.

Who may claim for a deceased owner

A claimant gives their mailing address and their relationship to the owner: owner, heir, or representative.1

Documents for an heir or estate claim

Under SDCL 43-41B-25, a claim is filed on a form prescribed by the administrator and verified by the claimant.3

Each claim requires a completed, signed claim form, a copy of a photo ID and a Social Security number. Any other requirements are listed on the form the portal generates.1

To prove a right to claim for a deceased person, a claimant may submit the court order documents showing appointment as personal representative or executor: the will, court appointment, or probate.4

Claiming without a probate order

If the deceased did not have a will, an affidavit of small estate may be submitted if the requirements of SDCL 29A-3-1201 are met.4

SDCL 29A-3-1201 allows the successor affidavit when the entire estate, less liens and encumbrances, does not exceed $100,000, 30 days have passed since the death, and no application or petition for appointment of a personal representative is pending or has been granted.5

The decedent must also have incurred no indebtedness to the Department of Social Services for medical assistance for nursing home or other medical institutional care. Any holder of the decedent's personal property, bank accounts or securities, including unclaimed property, must then transfer it to the successor.5

Processing time

Under SDCL 43-41B-25, the administrator considers each claim within 180 days after it is filed.3

If a claim is denied

Under SDCL 43-41B-25, the administrator gives the claimant notice if the claim is denied in whole or in part.3

Deadline to claim

The State Treasurer's portal states that "the State holds these lost funds until claimed by either the original owner or their heirs," so an heir may file a claim at any time.1

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