now try again using the word “title” somewhere. you really think he’s going to sign over the title with a lean on it for a truck like this.
what happens in 90% of these cases is that the truck breaks down and she can’t afford to fix it an stops paying because he obviously sold a lemon then they both end up on judge judy for my entertainment.
also note that a notary does not make a contract legally binding, it just means that on a given date and time somebody signed a piece of paper.
