not really. he just has to be there to say he filled it out. they dont have to watch him do it. you should both take an ID just in case. im not saying its impossible to find a notary who will do it, but they will definitely be the exception, not the rule. otherwise, someone could steal a title, fill in the info, and then get it notarized and "sell" it to themselves. then they own the vehicle. sorta like a bank taking third party checks. they want both parties to come in and verify their signatures. otherwise i could steal a check written to you, sign your name then write pay to the order of me, and cash it.
