Generally, the bill of sale goes along with the title when the buyer presents documentation to change over the title into his or her name, and to register the vehicle as its new owner. In Ohio, this process falls on the County Clerk's office. The bill of sale goes to the office along with the title for processing. The buyer may also be required to show a bill of sale at the DMV. Buyers and sellers should keep a copy of the bill of sale on hand. The buyer can use it to meet any challenges regarding ownership, and the seller can use it is a Release of Liability, where the individual cannot be responsible for claims related to the vehicle when it has been legally sold. It's important to note that the seller may also have to contact the DMV about the sale in order to be released from liability.
