This document can be prepared by the buyer or the seller. This Bill of Sale is not designed for use in connection with real estate transactions. Instead, a Bill of Sale serves as a proof of purchase for the buyer, and confirms that the buyer has actually paid for the goods, and is now the owner of the goods. By signing the document, the parties are agreeing that on some future date, the buyer will pay the agreed price for the goods, and the seller will hand the goods over to the buyer. This means that a Bill of Sale serves quite a different purpose from a Sale of Goods Agreement, (or a Vehicle Sale Agreement, in the case of a vehicle), although these documents look quite similar and may have many things in common.Ī Sale of Goods Agreement is generally signed and exchanged between the parties ahead of time. A Bill of Sale identifies the goods that are being transferred and allows the buyer to prove ownership of the goods, if there is a later dispute. It acts as a proof of purchase, and is usually exchanged at the time that the ownership is actually transferred (for example, when car keys are handed over in exchange for cash). A Bill of Sale is a document that is used to transfer ownership of a good or goods from a seller to a buyer.
