Unclaimed Money in Montana
Search Montana unclaimed property — also called missing money — for free. Montana holds it indefinitely until you or your heirs claim it.
How Montana's unclaimed property works
When a business in Montana can't reach you to return money — an uncashed paycheck, a forgotten checking account, a security deposit — state law requires them to turn it over to the state's unclaimed property division after a dormancy period. The money sits there indefinitely, waiting for you (or your heirs) to claim it.
What makes Montana different
Montana is small in population but disproportionately heavy in oil-and-gas and mineral royalty interests on its unclaimed property roll, especially Bakken-adjacent acreage in the eastern part of the state. The transient seasonal workforce (Glacier and Yellowstone tourism, ski towns, oil patch crews) drops a lot of final paychecks into the system. Unclaimed property sits in the Department of Revenue rather than under the Treasurer, which lets the state cross-match against tax filings.

Frequently asked questions about Montana unclaimed property
Yes. Montana returns your money directly. There is no fee to file or claim through the official portal.
Indefinitely. Montana, like most states, does not extinguish valid claims — the money waits for you or your heirs as long as it takes.
Yes. You'll need a death certificate, proof of relationship, and (often) probate documents from Montana or the state of residence. Heir claims are higher-value but more paperwork — consider a state-licensed recovery service for complex cases.
Often yes. Small fractional Bakken-area mineral interests, especially after multiple generations of inheritance, are one of the most common categories on Montana's roll. Search by every family name that may have held the interest.
Frequently yes — seasonal hospitality payroll is a major source of unclaimed Montana wages because workers leave the state before final pay reconciliations reach them.
