Credit Card Glossary: Terms and Definitions

Written statement of unauthorized debit (WSUD)

A written statement of unauthorized debit (WSUD) is a form that must be filled out by bank customers who find bogus or incorrect debits in their accounts. The form is supplied by a financial institution where the charge took place, and it initiates the process of reversing an ACH debit that the card user says was unauthorized, ineligible or improper, or for which the authorization has been revoked. The consumer must file the WSUD within 60 days after transmittal of the first bank statement showing the unauthorized transaction.
