My friend passed away from cancer last month. I signed for a car in my name for her because her last car was in her and her husband's name and he came and took the car when she was sick with breast cancer and needed the car to get to chemothrapy...they had separated and weren't living together. He did not pay the car payment because he was using drugs and she wouldn't pay it because she couldn't use it. She signed a letter stating that she was making the car payment. Do I have the legal right to make a claim against her estate?
