What Is a Bill of Sale for a Vehicle?
A vehicle bill of sale is a written document that records the details of a private vehicle sale. It identifies the buyer, seller, vehicle, sale price, and date of the transaction. Some states require it; most experts recommend it even when it is not required.
What should a bill of sale include?
A complete bill of sale should include: full legal names and addresses of buyer and seller, vehicle year, make, model, body style, color, VIN, odometer reading at time of sale, sale price, date of sale, and both parties' signatures.
Is a bill of sale required to sell a car?
Requirements vary by state. Some states require a bill of sale to register a vehicle; others do not. Even where not required, a bill of sale protects both parties by creating a written record of the agreed-upon terms.
Does a bill of sale replace a title?
No. A bill of sale documents the transaction but does not transfer legal ownership. The signed title is what transfers ownership. Both documents together provide the strongest protection for buyer and seller.
Does a bill of sale need to be notarized?
Notarization requirements vary by state. Louisiana, for example, has historically required notarized bills of sale for vehicle transactions. Check your state's official motor vehicle agency for current requirements.
Frequently asked questions
Can I write my own bill of sale?
Yes. A handwritten bill of sale is generally valid as long as it includes the essential information. Many state DMV websites offer free bill of sale templates.
Does a bill of sale prove ownership?
It documents that a sale occurred, but the signed title is the legal proof of ownership. Keep both documents.
