Card Holder Agreement is the statement specifying the terms and conditions associated with a particular credit card. Lenders are legally obliged to provide prospective card holders with a card holder agreement that spells out, among other things, the card's APR(s), terms of use, service charges, payment terms and the card holder's billing rights. However, a lender may change the terms and conditions in a card holder agreement at any time, provided it gives sufficient advance notice to the card holder.
