How do I write a bill of sale for a car?
List the buyer and seller, describe the car (year, make, model, VIN, color), record the odometer and the price, add the date, and have both parties sign. Our generator builds all of this for you and checks for missing details.
Can I sell a car without a bill of sale?
In some states you can transfer with just the signed title, but a bill of sale is strongly recommended everywhere because it documents the price, the mileage, and the date you stopped being responsible for the car.
Is a bill of sale proof of ownership?
Generally no. For titled property like a car or boat, the title is what proves ownership. A bill of sale proves that a sale happened and records the price, date, and terms — it supports the title transfer but does not replace it. For untitled property (furniture, equipment, electronics), the signed bill of sale is usually the main proof of ownership.
