Where to search Montana unclaimed property
The official public search is mtrevenue.gov/unclaimed-property, operated by the Montana Department of Revenue under Mont. Code Ann. § 70-9-801 et seq.. It is free, requires no account, and is the only site authorized to process your claim. Anything else — a .com lookalike, a mailed offer, a caller asking for a release fee — is either a private finder or an outright scam.
Montana holds unclaimed mineral and coal royalty payments alongside standard bank and payroll property.
What the MT program holds
- Uncashed paychecks, final wages, and commissions
- Dormant checking and savings account balances
- Utility, cable, and rental security deposits
- Insurance refunds and life insurance death benefits
- Stocks, bonds, mutual fund shares, and unpaid dividends
- Contents of abandoned safe-deposit boxes
- Money orders, cashier's checks, and traveler's checks
- Court settlements, class action distributions, and escrow balances
- Credit balances, vendor overpayments, and refunds
How to search so you don't miss anything
- 01Enter your last name only and leave the city field blank — city filters are matched against the address the holder had on file, which is usually outdated.
- 02Search every prior legal name: maiden name, previous married names, hyphenated versions, and common misspellings.
- 03Search deceased parents, grandparents, and any relative whose estate you may inherit from.
- 04Search every business, DBA, LLC, or trust you have registered.
- 05Search every Montana address from the last 30 years — including Billings, Missoula, Great Falls, Bozeman, and Butte.
- 06Repeat all of the above in every other state you have lived, worked, or banked in.
Documents Montana will ask for
- Government-issued photo ID (Montana driver's license, state ID, or passport)
- Social Security number verification — often only the last four digits for small cash claims
- Proof of the address on file when the property was reported: an old utility bill, lease, tax return, or W-2
- For a business or trust: formation documents, EIN letter, and proof you are an authorized signer
- For a deceased owner: certified death certificate, proof of relationship, and either a small-estate affidavit or Letters Testamentary
Avoiding Montana unclaimed property scams
The Montana Department of Revenue never charges a fee, never calls demanding payment, and never asks for a wire transfer, gift card, or cryptocurrency to release funds. Private finder fees are capped at 10% under Mont. Code Ann. § 70-9-801 et seq.. If a letter routes you to a .com domain instead of the official portal, verify it yourself before signing anything. Here's how to tell a real state site from a scam.
Bottom line
Montana unclaimed property is real, free to claim, and never expires. Spend ten minutes at mtrevenue.gov/unclaimed-property searching every name your family has used. Then check the other states you've lived in and the federal databases — most people who find money find it somewhere they'd forgotten about.
