An Iowa Bill of Sale is a legal document that is used to transfer the ownership of a certain good from one person to another. The Iowa Bill of Sale is used to prove that a legal sale and purchase has taken place and is typically required for the transfer of motor vehicles in the state. The Iowa Bill of Sale must be signed by both the buyer and the seller and must include the details of the goods, the sale price, and the date and place of the sale. There are two types of Iowa Bill of Sale: Iowa Motor Vehicle Bill of Sale and Iowa Boat and Vessel Bill of Sale. The Iowa Motor Vehicle Bill of Sale is used to transfer the ownership of a motor vehicle, such as a car, truck, or motorcycle, from one person to another. The Iowa Boat and Vessel Bill of Sale is used to transfer the ownership of a boat or vessel, such as a boat, jet ski, or sailboat, from one person to another.
