What You Need to Know about Credit Card Fraud Disputes?

Card issuers must receive written notice of a disputed transaction within 60 days of the statement containing the charge. Upon receipt of a written dispute, the issuer has 30 days to acknowledge the dispute and begin investigation, and must complete the investigation within two billing cycles (typically 90 days). If the issuer fails to meet these deadlines or does not properly investigate, the burden of proof may shift, and the cardholder may have grounds for a claim. From a practitioner's perspective, these deadlines are strictly enforced, and corporations must implement internal systems to track dispute notices and ensure timely responses.

Unlike criminal fraud cases, which require proof beyond a reasonable doubt, civil credit card disputes operate under a preponderance of the evidence standard. The card issuer bears the burden of proving that the transaction was authorized, or if unauthorized, that the cardholder bears responsibility under the terms of the card agreement. The Regulation Z framework (implementing the Truth in Lending Act) further limits cardholder liability for unauthorized charges to a maximum of fifty dollars if the cardholder reports the fraud promptly. Corporations must understand that this burden allocation differs fundamentally from how courts treat criminal fraud allegations, making the evidentiary and procedural stakes distinct in each context.

Merchants must retain transaction records that demonstrate authorization, such as signed receipts, electronic authorization codes, or cardholder verification data. In cases involving online or card-not-present transactions, merchants should maintain records of delivery confirmation, IP address logs, or other evidence of cardholder receipt or use. When a dispute arises, the merchant's documentation becomes the primary evidence that the issuer uses to defend against the cardholder's claim. Incomplete or missing documentation often results in the cardholder prevailing, as the issuer cannot rebut the unauthorized transaction allegation.

If the card issuer determines the transaction was unauthorized, the issuer may issue a chargeback, debiting the merchant's account and crediting the cardholder. Merchants have the right to dispute a chargeback by submitting a representment package containing evidence that the transaction was authorized or that the merchant complied with card network rules. In New York state courts and federal courts handling merchant disputes, the timing and completeness of the representment submission are critical; late or incomplete submissions may result in the court declining to consider the merchant's evidence, leaving the chargeback standing. Corporations managing merchant accounts must establish clear procedures for gathering and submitting representment documentation within card network deadlines, which typically range from seven to fourteen days depending on the card brand.

Visa, Mastercard, and other card networks impose specific requirements for fraud prevention, dispute handling, and merchant compliance. Corporations that exceed chargeback thresholds may face fines, restricted processing privileges, or termination from the network. These network rules operate independently of FCBA compliance and often impose stricter standards than the federal statute requires. Maintaining detailed records of authorization, implementing address verification systems, and using fraud detection tools are practical measures that reduce both chargeback frequency and regulatory exposure.

When a corporation violates FCBA procedures, the cardholder may pursue a private action for damages equal to the amount of the disputed charge plus twice that amount in statutory damages, capped at one thousand dollars per violation. Additionally, the Consumer Financial Protection Bureau and state attorneys general may bring enforcement actions against corporations for systematic FCBA violations. A corporation that receives multiple complaints about delayed dispute investigations or failure to provide provisional credits may face regulatory scrutiny and mandatory remediation, including refunds to affected customers and operational changes to dispute handling procedures.
