In the state of New York, you generally cannot register a car with just a bill of sale and no title. The new owner must give the original bill of sale to the DMV along with the other required proofs of ownership when they title and register the vehicle.If the proof is not available, the applicant can use the Statement of Ownership (PDF) (MV-51B) for proof of ownership. Does anyone know if one can title a car in NJ when car was bought out of state without a title?
