My fiance's grandmother passed away a few years ago and left her car to him. We've been waiting for the probate to go through so that he could get the title however there's been issues with an estate that she owned so the process has been drastically delayed. I recently accepted a job offer in New York and so now we're looking to sale the car as soon as possible but would obviously need the title to do so. We started the process of getting the title via an Affidavit of Heirship however my fiance's mother (also an heir) is unwilling to cooperate and is refusing to sign. If we don't get this figured out before the move, we're looking at some serious financial trouble and additional complications due to us being in a different state. Is there anything we can to do to get this taken care of without having to get his mother's signature?
