Montana unclaimed money and property: is it yours?

Where to search Montana's official unclaimed property list for free, what happens to forgotten safe-deposit boxes there, and whether the money is still yours after a sale.

Safe-deposit boxes

Does Montana auction unclaimed safe-deposit-box contents?

Yes. Montana held or listed a state sale in 2025–26. The Department of Revenue's unclaimed property page links a live online auction for public sale of abandoned property under MCA 70-9-812(1).

Not yet verified: The page doesn't name the auction platform, and we didn't follow it, so we can't say which site hosts the lots.

Read the full Montana auction guide: who runs it, how often, past sales and where to bid.

After a sale

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

The Montana pages we read don't say what happens to the money after a sale. Ask Montana Department of Revenue directly; its contact details are on the official site ↗.

How to check

How do I check Montana for free?

  1. Open Montana's official search: revenue.mt.gov ↗. 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 ↗
