There's a bit more on the bill of sale form for Ohio sales than some other states include. The basic recorded information starts with names, addresses and contact information for both the buyer and the seller. The year and make of vehicle are recorded, along with the VIN number, that is the serial number for the vehicle. Along with this basic data, the Ohio bill of sale form includes portions for recording warranty and inspection information, as well as an odometer reading. States use odometer information to try to prevent odometer fraud on vehicles, where previous owners may roll back or tamper with the manual odometer. Digital odometer styles have limited this kind of activity by dishonest car sellers. The Ohio bill of sale also includes a "promissory note" section. This is information regarding satisfying any lien on the vehicle, where the owner will owe money to a lender who is helping to finance the sale.
