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.
