Montana unclaimed property: search and claim your money (2026)

What counts as unclaimed property in Montana

Montana's Unclaimed Property Program, run by the Department of Revenue, is the state's holding account for money that businesses, banks and government agencies could not return to the rightful owner. When a checking account sits untouched for years, a final paycheck is never cashed, or an insurance benefit letter comes back undelivered, the holder is legally required to transfer that money to the state under the Uniform Unclaimed Property Act. The state then holds it — indefinitely, in most cases — until you or an heir shows up to claim it.

Typical categories include:

• Dormant checking, savings and CD accounts
• Uncashed payroll, vendor and refund checks
• Utility and rental security deposits
• Life insurance proceeds and annuity payments
• Stocks, bonds, mutual fund shares and unpaid dividends
• Contents of abandoned safe deposit boxes
• Court deposits, escrow balances and traveler's checks

Real estate is not unclaimed property — that is handled through separate tax-deed and probate processes. Everything else that a Montana-registered business owes you and cannot deliver eventually ends up here.

How to search the Montana database (and why to check twice)

Start at the official state site: mtrevenue.gov/unclaimed-property. The search is free, requires no account, and returns matches by name and city. Then repeat the search on MissingMoney.com, the NAUPA-endorsed multi-state tool, because holders sometimes report Montanans' property to the last state where they lived or worked.

Search variations most people miss:

• Maiden name and any prior married names
• Nicknames and middle initial vs. full middle name (Jim / James / J.)
• Common misspellings a data-entry clerk might introduce
• Business names, DBAs and estates you administer
• Deceased parents, grandparents and spouses

If you have lived out of state, also check the neighboring programs (Wyoming, Idaho, North and South Dakota) and every state you have had an address in. The full state directory is at unclaimed.org. A single missed variation is the difference between finding $28 and finding a $3,400 stock account your grandmother forgot she opened.

How to file a Montana unclaimed property claim

When you find a match, click through to start a claim on the state site. Montana's process is designed to be handled online, though paper claims are still accepted. You will be asked to identify yourself, prove you lived at the address the holder reported, and — for larger accounts — provide notarized signatures.

The state will never call, text or email you first asking for a fee, gift card or bank login. If anyone does, it is a scam.

1. Search your name at mtrevenue.gov/unclaimed-property and select every property that could plausibly be yours.
2. Start the online claim and download the pre-filled claim form.
3. Gather ID (driver's license or state ID) and proof of your connection to the reported address (old utility bill, tax return, lease, W-2).
4. For estates, include the death certificate and letters testamentary or a small-estate affidavit under Montana law.
5. Sign the claim (notarization is required above the state's threshold, typically for higher-value claims).
6. Upload documents through the portal or mail them to the address on the form.
7. Track your claim status by logging back in; most claims resolve in 30–90 days.

Documents you'll need (and how long processing takes)

Documentation requirements scale with the size and type of the claim. A $40 utility refund needs almost nothing; a $12,000 brokerage account needs a paper trail. Gather everything up front to avoid the back-and-forth that stretches processing from weeks to months.

Claiming for a deceased relative or a business

If a Montana relative died with unclaimed property in their name, you can claim it as an heir or as the personal representative of the estate. For estates worth $50,000 or less in personal property, Montana allows a small-estate affidavit that avoids full probate — you sign a sworn statement 30 days after death and present it with the death certificate. Larger estates need letters testamentary from a Montana district court.

Businesses can also have unclaimed property: refunds owed to a dissolved LLC, uncashed vendor checks, or old utility deposits from a closed storefront. To claim on behalf of a company, you need the entity's EIN, proof of good standing (or dissolution paperwork showing you as an authorized wind-down officer), and a corporate resolution if multiple owners are involved. Sole proprietors just document the DBA.

Multiple heirs? Every heir generally needs to sign, or one heir needs signed disclaimers from the others. Bring more paperwork than you think you need — a rejected claim can be re-filed, but it adds months.

Finder fees, scams and what to ignore

Private "asset recovery" companies scan state databases and mail letters offering to reunite you with your money for a cut — often 10–40%. Montana caps how much a finder can legally charge and prohibits contact until property has been held for a set period, but the safer answer is simpler: you never need a finder. The state's search and claim process is free, and the same records these firms use are on the public site.

Red flags to walk away from:

• Urgent calls or texts saying you must "verify" your Social Security number to release funds
• Anyone asking for a wire transfer, gift card or crypto payment
• Emails claiming to be from "Montana Treasury Unclaimed Division" (the program is at the Department of Revenue, not a treasury)
• Offers that require you to open a new bank account or share online banking credentials
• Sites that charge a search fee — the official one never does

If you already signed a finder contract and regret it, Montana law generally lets you cancel within a short window; check the contract and consult the Department of Revenue directly.

Money the state doesn't hold: class-action settlements

State unclaimed property is only one bucket of "money you might be owed." Another big one is class-action settlements — payouts from lawsuits against companies you bought from, banked with, or used an app from. These do not show up on mtrevenue.gov because a private settlement administrator (not the state) holds the funds and mails checks only to people who file a claim before the deadline.

To learn how these work, see what a class action is, how the process works end-to-end, and how to check whether you're in the class. Many settlements pay without proof of purchase, with typical no-proof payouts in the $10–$150 range. Browse current open settlements, or see what you're owed in about 30 seconds — Owed matches you to eligible class actions and files them for you, free.

Do both: claim your Montana property from the state, and check for open settlements you qualify for. They are separate pools of money.
