A Bill of Sale is a document created by a buyer and a seller as a means of documenting the sale of a motor vehicle. To be a legal document, the Bill of Sale must contain the following information:
- The buyer's name, address, and signature
- The seller's name, address, and signature
- The model, make, model year, and Vehicle Identification Number (VIN) of the vehicle
- Date of purchase
- Purchase price
- Odometer reading
In Massachusetts, a Bill of Sale does not need to be notarized.
