Hi, I am in located in California and am looking to purchase a vehicle off someone who has started the registration process but had not completed it due to the lack of a smog check. The person is able to drive the car legally somehow, I believe the DMV did not finalize the registration or title transfer due to the lack of a smog check. He does not have the bill of sale between him and the last owner, however, the title is signed off and his information written on the back of the title. Will I be able to transfer the title to my name if I purchase the car with his name on the back of the title and without a bill of sale between him and the previous owner, or will a bill of sale between him and I be sufficient? Thank you in advance!
