Facts you can cite

• Process

  Santander's guide says the issuer has one month to acknowledge a credit card dispute and must resolve it within 90 days (two billing cycles). You do not have to pay the disputed amount while it is investigated, but the issuer may temporarily lower your credit limit by that amount.

Rules in force

• Fair Credit Billing Act billing-error and purchase-dispute rights (Regulation Z)
  12 CFR 1026.13; 12 CFR 1026.12(c) (Regulation Z)

  For credit card and other open-end credit accounts, a written billing-error notice that the creditor receives within 60 days after it sent the first statement with the error starts a dispute process. The creditor must acknowledge it within 30 days and resolve it within 2 complete billing cycles (no later than 90 days). Until then, the consumer need not pay the disputed amount and the creditor may not collect it or report it as delinquent. A separate rule lets a cardholder assert claims and defenses about a card purchase against the card issuer.

  2 citable points

  • Policy

    Claims and defenses (12 CFR 1026.12(c)): when a merchant does not resolve a dispute about property or services bought with a credit card, the cardholder may assert against the card issuer all claims (other than tort claims) and defenses from the transaction, and may withhold payment up to the amount of credit outstanding for that purchase plus related charges. The issuer may not report that withheld amount as delinquent until the dispute is settled or judgment is rendered.

  • Limit

    Claims-and-defenses limits: the cardholder must first make a good faith attempt to resolve the dispute with the merchant, the purchase must exceed $50, and it must have occurred in the same state as the cardholder's current designated address or within 100 miles of it. The $50 and location limits do not apply when the merchant is the card issuer, is controlled by or controls the issuer, is a franchised dealer in the issuer's products, or got the order through a mail solicitation the issuer made or took part in.
