How to Sell a Car Privately in Montana (2026 Guide)
Quick Answer
To sell a car privately in Montana you need: a signed title, a completed bill of sale (VIN, sale price, odometer, date, both signatures — notarized), and photo ID. The buyer has 30 days to transfer the title at the Montana DMV and pay the $12 transfer fee.
Montana-Specific Note
Montana requires a signed bill of sale for all private vehicle sales. Both buyer and seller should keep a signed copy for their records.
Step-by-Step: How to Sell a Car Privately in Montana
Follow these 7 steps in order. Do not skip step 6 — a missing or incorrect bill of sale is the #1 reason title transfers are rejected by the Montana DMV.
- 1Price your vehicle using Kelley Blue Book (kbb.com) and Edmunds (edmunds.com) to establish fair market value. Cross-reference at least two sources. Set your asking price 5–10% above your walk-away number to leave negotiating room.
- 2Gather your documents before advertising: the clear title (no open liens), valid government-issued photo ID, maintenance records, and any warranty paperwork. If there is an open lien, contact your lender to arrange a payoff and lien release before listing.
- 3Run a VIN history report and share it with prospective buyers. Reports from Carfax or AutoCheck cost around $40 and show accident history, odometer records, and title status. Serious buyers expect this — having it ready prevents the "I need to check the VIN" negotiating tactic.
- 4Photograph and list the vehicle with full details: mileage, options, maintenance history, and known condition. State "as-is, private sale" clearly in the listing. Use at least 10 photos taken in daylight from multiple angles.
- 5Screen buyers: allow test drives only after requesting a valid license. Meet in a public location (a bank parking lot is ideal — you can accept a cashier's check on the spot). Never allow an unsupervised test drive.
- 6Complete a Montana bill of sale at the time of the sale. Both buyer and seller must sign. The document must include the VIN, sale price, odometer reading, sale date, and full names and addresses of both parties. Note: Montana requires the bill of sale to be notarized — both parties must sign in front of a licensed notary public.
- 7Sign over the title to the buyer. The seller signs the assignment section on the back of the title. Double-check every field — an incorrect title is rejected by the Montana DMV. The buyer has 30 days to complete the title transfer.
Required Paperwork for a Montana Private Car Sale
Signed vehicle title
The seller signs the back of the Montana title in the assignment section. Fill in the buyer's full legal name, sale price, and date. Do not leave any field blank.
Bill of sale
Must include: buyer and seller full names and addresses, VIN (17 characters), year, make, model, odometer reading in miles, sale price (written and numeric), sale date, and both parties' signatures — notarized in front of a licensed notary public.
Odometer disclosure
Required by federal law (Truth in Mileage Act) for vehicles under 10 model years old. Montana also requires odometer disclosure under state law. Record the exact odometer reading at the time of sale.
Notary seal (required in Montana)
Both buyer and seller must sign the bill of sale in front of a licensed notary public. Do not sign in advance. Bring valid government-issued photo ID. Notaries are available at most bank branches, UPS Stores, and Montana DMV offices. Cost: $5–$15.
Government-issued photo ID
Both parties should bring a valid driver's license or state-issued ID. This confirms identity and reduces fraud risk. Make a photocopy for your records.

Protect Yourself After the Sale
Signing over the title and handing over the keys does not automatically end your liability in Montana. If the buyer is involved in an accident, receives a traffic citation, or accumulates unpaid tolls before transferring the title, you may receive notices — or worse, have your license suspended.
Notify the Montana DMV of the sale within a few days to remove yourself from liability.
3 Common Mistakes When Selling a Car in Montana
Not gathering all documents before the meeting — bring the signed title, bill of sale, valid ID, and any service records.
Missing the title transfer deadline — the buyer must complete the transfer within the required window to avoid late fees.
Not filing a notice of sale with the Montana DMV — this protects sellers from post-sale liability.

How much is the title transfer fee in Montana?▾
The title transfer fee in Montana is $12. This fee is paid by the buyer at the Montana DMV at the time of registration. In addition to the title fee, the buyer pays Montana vehicle sales tax: No sales tax; registration fee based on age and value. Registration fees are also due at that time.
Can I sell a car without a title in Montana?▾
Selling a vehicle without a clear title in Montana is strongly discouraged and may be illegal. If you have lost the title, apply for a duplicate title at the Montana DMV before listing the vehicle.
