Fill Out a Montana Bill of Sale Online in 2026

A Montana bill of sale is a written document that records the private sale and transfer of personal property—such as a motor vehicle, boat, or other asset—from a seller to a buyer. It provides legal evidence of the transaction and documents the key terms: the names and addresses of both parties, a description of the item, the sale price, and the date.

Montana does not have a single mandatory state-issued bill of sale form. Any clearly written document capturing the essential transaction details is legally recognized. For motor vehicle title transfers, a bill of sale or other evidence of ownership transfer is typically submitted to the Montana Motor Vehicle Division (MVD) to support the title application and determine applicable fees.

A Montana bill of sale is used to formally document the transfer of personal property and protect both parties in a private sale. Specifically, it is used to:

• Document the transfer of personal property (vehicle, boat, firearm, equipment, or other items) from seller to buyer
• Establish the agreed purchase price on record — Montana Motor Vehicle Division uses this to calculate applicable sales tax, use tax, or registration fees when the buyer applies for a new title
• Protect the seller from future liability related to the property after the sale date
• Give the buyer proof of ownership pending receipt of a new title
• Serve as evidence in any dispute about the terms, price, or condition of the item at the time of sale
• Support insurance documentation — the buyer can present the bill of sale to their insurer as proof of acquisition and value

A complete Montana bill of sale should include the following information:

• Full legal name and current address of the seller
• Full legal name and current address of the buyer
• Detailed description of the item being sold — for vehicles: year, make, model, color, body type, and VIN; for other property: a clear description with any serial number
• Agreed purchase price
• Date of the transaction
• Current odometer reading at the time of sale (required by federal law for all motor vehicle transfers)
• Signatures of both the buyer and the seller

Montana does not universally require a bill of sale for private property sales. For motor vehicle title transfers, the Montana Motor Vehicle Division requires the seller to sign the certificate of title. A bill of sale serves as supporting documentation and helps establish the purchase price for fee calculations.

For vehicles titled in other states or with unusual ownership situations (such as estate sales), a bill of sale or affidavit may be required as part of the title application.

No. Montana does not require a bill of sale to be notarized. A Montana bill of sale is enforceable without notarization for personal property transactions, including motor vehicles.

While notarization is optional, it can add credibility to the document in high-value transactions or if there is any concern about the authenticity of the signatures.

A Montana bill of sale has no expiration date. Once both parties sign it, it becomes a permanent legal record of the transaction. Neither party needs to renew or re-execute the document—it remains valid indefinitely as long as it accurately reflects the completed sale.

Both the buyer and the seller should keep their signed copies for their personal records. For vehicle transactions, retain the bill of sale until the Montana Motor Vehicle Division has processed the title transfer and issued a new title in the buyer's name. The document may also be needed as proof of purchase for insurance, tax verification, or future ownership disputes.
