<prompt> Human: Hi guys,My dad is an authorized user on my AMEX account, and has his own card under my credit line. Hes spent over 10k and is paying the minimum amount each month. My balance is 0, and I dont want to be associated with the card anymore.Is there anything I can do?  <response>: Remove him as an AU. Unless the charges were made fraudulently, you are 100 on the hook for it. You can however sue your father for the amount owed if he fails to make a payment.
