I'm his wife but we seperated n 6months later he died he bought me the car n was paying on it the whole time. My credit sucks so they said they probably couldn't redo it with me. They know where the car is never got back to me to send me hardship paper work then charged it off. That was 2yrs ago and I would like to keep it it was the last thing he bought me. What do i do or can I do . he left no insurance or will n had to sell the house b4 he died to pay all the liens he had on it.
