My daughter traded in a car for a new car when she was living with her ex-boyfriend. Her credit was bad and his was great. The dealer had him sign for the car and had her as the co-signer. They say that will help her credit in the long run to build it up. My question is this "whose car is it", since they have now broken up. Can he go back and take the car now even though she has made all the payments. She tells me know but I think she is wrong. If she keeps the payments up and continues paying on the car can he come and get it after it is paid off? Also if she decides later to sell it will she need his signature? If you can answer these questions for me i would appreciate it. Thank you.
