Steps to take

  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.
