Under the Truth in Lending Act (TLA) cardholders can only be liable to a card issuer for a maximum of $50 if your card is stolen and used by someone else. Once you notify the issuer, you are no longer liable for any further transactions completed with your stolen card. The $50 charge is only incurred if the stolen card is used illegally before you notify your credit card company. The card issuer has the burden of proof of showing any purchases were authorized by you if you claim your card was stolen.
