Ok feel dumb because I have just read a few of the same questions, but I purchased a vehicle from a guy, had him sign the bill of sales saying id receive the title clean and clear of any leans or loans within 10 days. That was a month ago and still nothing. He keeeps saying he sent it, but I'm not thinking so? What should I do?

You've been had.
All you can do is sue him and also go to your DMV and see what they say, since it varies by your state and his state, age of car, and so on.

I don't think suing him is going anywhere unless you can prove fraud or that he never owned the vehicle. Think about it, you both stand up in court and he says he mailed it and you say you don't think so. Sounds like something a judge would laugh at to me. You should be able to apply for a duplicated title via the Secretary Of State's office. You made a big mistake in giving money to someone who could not transfer the title on the spot.

Right, the owner should apply for a duplicate. He then uses the duplicate to put the vehicle in your name. Give him a period to do that. If he doesn't or refuses, then sue him.

You can't prove he didn't mail it.

I would go to DMV and see if they will issue a new title based on the Bill of Sale.
