I bought a used car about a month ago. I was told I have thirty days to file the registration paperwork, so I'm nervous. What happens if I miss the deadline? Is there a fine for filing late? Also, I'm not really sure of the process. Do I have to go somewhere in person? where? Or can I just mail it or do it online? A friend of mine (French) bought a used car and never filed for registration. He never got pulled over, so it wasn't a problem. He got hit by another car and his vehicle was totalled, so the insurance company just took the wreck and paid him for it, apparently without any problem. What about selling an unregistered vehicle to another person? Is that possible? I have the cancelled and signed carte grise from the previous owner and the paperwork we filled out when he sold it to me. Sorry for being so scatterbrained, I know I asked a ton of questions. Thanks.
