<prompt> Human: A little background: My sister got arrested for domestic violence, false imprisonment, and Im not sure what else and my parents and I went to bail her out and they told us that someone with a bank account need to sign. Since they didnt have one, it was up to me to sign. She was making payments and I thought she was, until a few days ago when I received a letter stating the balance at about 3,000 already in collections. She has a job and had been having one so Im not sure whats going on. We were never close, but Ive told her multiple times to keep up with her payments. Ive had it and Im hoping you guys can give me AT LEAST advice on what I can do. Thanks!  <response>: Nope. Never cosign a loan for anyone. Theres a reason they needed you to cosign, and youre now finding out why.Your only real option is to make the payments yourself and sue your sister in small claims court. The fact that the loan is in collections means your credit is being damaged by the lack of payment. Remember you cosigned on the loan, so youre responsible for it too.Hopefully you documented that this was a loan. That means having a simple contract with your sister stating it was a loan, the amount, as well as stipulating repayment terms. This makes it easier to sue in court, otherwise she can try to argue that there was no loan and that you offered to help her pay as a gift.
