My daughter's ex-boyfriend helped her spend a school loan for $5000 which I was co-signed on. He was 21 at the time. I have since paid it because I want my credit to be safe. I have thought about taking him to court but never once considered asking his parents to pay for his mistakes. I know my mom has paid for credit cards that my sister (not an addict, shopaholic) has abused that belonged to an ex-husband of hers. Why my mom does it, I don't understand because it never stopped my sister from finding another person to use. Asking his parents to pay only puts the burden on them and if they are good people, it will probably make them feel guilt that they don't own. Present the evidence to them in person and don't demand that they make payment. If they want to do it for you, then so be it. Hugs, Marle
