<prompt> Human: I took out a 5-year car loan about 2.5 years ago, with help from a family member in two ways: interest-free personal loan of 6k toward the down payment, and they cosigned on the bank loan as well.Fast forward to today, and this family member and I are no longer on good terms. Theyve just called in the personal loan, saying I need to repay it. Luckily, I can cover it, so thats not really an issue. However, Im not sure where my relationship with this person is headed - in fact, it may be going south quickly.Is there anything they can do to harm me financially as the cosigner on my loan? What can I do to protect myself?  <response>: Co-signer on a loan has literally zero benefits and pretty much all the responsibility. They are probably worry that you are going to default and make them pay back the loan.financial advice aside, if someone has been good enough to give you an interest free loan and stick their neck out to co-sign something for you, perhaps you can do worse as far as familial relationship goes.
