Liability refers to the responsibility for charges to an account. Generally, a cardholder agrees to be liable for any charges to his or her account, including purchases, fees, and finance charges. If the cardholder allows someone else to make charges to his or her account (through, for example, an additional card), the cardholder is still responsible for paying the bill. Two people who apply for a card together may both be responsible for the entire balance. Your liability is described in the cardholder agreement you receive from the issuer. Be sure to read it carefully.
