I’ve heard of parents taking out loans/credit cards in a child’s name, spending all the money, and leaving the child to repay the debt. Did this happen to you? How did you deal with it?

I have a friend who’s currently in this situation and now has a lot of debts to repay. I know situations like this where a family member or close friend abuses you can be very difficult. If you had parents who did things like this to you, how did you deal with it? Did you have to pay everything back yourself? What would you advise?
