How to Sell a Car Privately in Montana
Selling your car yourself in Montana comes down to a signed title, the right paperwork, and a few steps people often miss. This guide summarizes what the Montana Department of Justice, Motor Vehicle Division and state law say, so you and the buyer can finish the transfer cleanly.
Transferring the title

- All owners listed on the title must sign it, and the buyer's name and address must be written on the title. mvdmt.gov
- Title fields must be completed in blue or black ink only, and white-out or scratching out entries voids the title. mvdmt.gov
- A bill of sale does not replace a Montana title. mvdmt.gov
- The buyer has 40 days from the sale date to transfer ownership at the county treasurer's office in their county of residence, and a $10 late fee applies after that. mvdmt.gov
Bill of sale
- The Bill of Sale (MV24) is optional, and it is listed as an option for a vehicle last titled in Montana, currently registered, and sold to a Montana resident. mvdmt.gov
- The seller is told to keep a written record of the sale that includes the buyer's name and address, which can be a photocopy of the reassigned title. mvdmt.gov

- The buyer is responsible for getting a temporary registration permit until they title and register the vehicle. mvdmt.gov
Taxes and fees the buyer pays

- Montana does not have a general sales tax. revenue.mt.gov
Loans and liens
- The seller must have any lien or security interest released before selling, and gives the buyer the lien release from the lienholder along with the title. mvdmt.gov

Easy-to-miss rules in this state
- A for-sale vehicle may only be displayed or parked on property the seller has a legal interest in, or with the owner's written permission displayed in the vehicle. mvdmt.gov
