When selling a vehicle most sellers utilize a bill of sale form to record information about the transaction, and if a seller lives in a state that does not supply its own required bill of sale form then free, printable forms are legally binding and acceptable. If a state does not require a particular bill of sale provided by the local department of motor vehicles (DMV), it may still dictate what type of information is required. The local DMV can answer questions about bill of sale forms.
Although a bill of sale records the details of the transaction, it is only when the title to a vehicle is transferred does liability switch over to the new owner. For maximum protection, transfer a vehicle title as soon as possible.
