Anyone can be a notary. The easiest way to get something notarized is to go to your bank. I think most places charge 15 bux for it. Also, even though your car is registered under your parents. Have you recieved the lean back from the bank on the loan that your parents (presumably) took out for your car? If you don't you aren't authorized, really to sell it, even though you could probably get away with selling the car first, and then go back to the bank for the rest of the info you need. Talk to your parents. They will know all of this, and how to proceed.

 

For some notories...they require both parties...you and your parents so that they feel comfortable with signing and stamping something.
