Where do I search South Dakota's unclaimed property?

How we know it's official: The State Treasurer's unclaimed property page links here. source ↗

What the official site says

• The site says unclaimed funds can be claimed at no cost with the proper identification. source ↗

Safe-deposit boxes

Does South Dakota auction unclaimed safe-deposit-box contents?

It can, but we haven't confirmed a dated state sale in 2025–26. South Dakota law (SDCL 43-41B-23) says that no earlier than three years after receiving abandoned property, the state sells it to the highest bidder at a public sale or by internet auction, whichever it judges the better market.

Not yet verified: We found no dated South Dakota sale on a state page.

After a sale

If the box was already sold, can I still claim the money?

The South Dakota pages we read don't say what happens to the money after a sale. Ask South Dakota State Treasurer directly; its contact details are on the official site ↗.

How to check

How do I check South Dakota for free?

1. Open South Dakota's official search: southdakota.findyourunclaimedproperty.com ↗. Check that the address is this one before you type anything in.
2. Search your name, any past or maiden names, and any business you ran. If a relative has died, search their name too: heirs can often claim. Ask the state office what proof it needs.
3. If you've lived or worked in other states, search those too. MissingMoney.com ↗, NAUPA's free site, searches most states at once and links back to each state's official claim page.
4. File the claim on the official site and send the proof it asks for, such as ID. Each state sets its own rules.

Finders

Do I need to pay someone to claim it?

No. NAUPA, the national association of state unclaimed property administrators, says there's no fee to search for and claim your property if you use your state's official program. Paid finders are legal in most cases but never required. Some states cap their fees and many require them to register, so check with the state office before you sign a finder's contract. NAUPA ↗
