Dispute Reasons

Modified on Tue, 10 Jan, 2023 at 8:06 PM

It is possible for a client to challenge a credit card payment once it has been made, requesting that their credit card provider reverse a payment on their card. There are various stages to a dispute and you as the person who received the payment may be asked for details of what the payment is for and you have the option to contest a challenge.

In this article, we explain the types disputes that there can be. You may also want to read our articles on Understanding Credit Card Disputes and Understanding What to Provide in your Response to Disputes.

KEY TERMS

Cardholder: The client that is disputing a transaction

Merchant: You, the law firm who provided the services being disputed

Issuing Bank: The bank that issued the card to the client (i.e. the cardholder’s bank)

Card Brand: The card brand the client’s card is associated with (Visa, Mastercard, Amex etc.)

Representment: The response a Merchant sends to the issuing bank when a transaction is disputed

Dispute Reasons

When a cardholder disputes a transaction, their issuing bank will request a detailed explanation of the problem from them. Once the issuing bank receives and validates the cardholder’s complaint, a dispute is initiated against the Merchant. There are many reasons for a cardholder to initiate a dispute which the issuing bank considers valid - and understanding each of these valid reasons will help the Merchant respond to disputes accordingly.

When a dispute is initiated it includes a reason code classifying the cardholder’s complaint. The actual reason codes vary by Card Brand, but disputes can generally be classified into four categories:

Fraud disputes

Fraud disputes occur when the cardholder claims their payment information was fraudulently used by another individual to purchase goods/services from the Merchant.

Authorization disputes

Authorization disputes occur when a Merchant submits a payment with an invalid or expired authorization code. For example, if a Merchant authorized their customer's card without fully completing the transaction, and then captured the payment - with a now-expired authorization code - at a later date, this may result in an authorization dispute.

Processing error disputes

Processing errors generally indicate a payment submission error by the Merchant resulting in the cardholder initiating a dispute. For example, this can include the Merchant submitting incorrect data or using the wrong payment method other than the one the cardholder intended for them to use etc.
