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.
