In Delaware, a Bill of Sale is not strictly required for selling an RV, but it is highly recommended for several reasons. A Bill of Sale serves as a legal document that establishes proof of ownership, confirms the transaction details between the seller and buyer, and provides an additional layer of protection to both parties involved. You can obtain a Bill of Sale form from the Delaware Division of Motor Vehicles website or use templates available on the internet. After filling it out correctly and getting it signed by both the buyer and seller, it serves as legal proof and a sale receipt. Once the sale is complete, the buyer and seller should keep copies of all documents for their records.
