A bill of sale is a legal document that records the transfer of ownership of an item from one person to another. It typically includes details such as the names of the buyer and seller, a description of the item being sold, the sale price, and the date of the transaction. This document serves as proof of the sale and can be important for both parties in case of disputes. In many cases, a bill of sale is used for transactions involving vehicles, equipment, or personal property. It can help protect the rights of both the buyer and seller by providing a clear record of the agreement. Some states may require a bill of sale for certain transactions, especially for vehicles like cars or boats.
