We have a customer who is claiming several checks paid from her account were forged. They are from two to six months old. I do not understand our account agreement, which provides 30, 60, or 120 days to report unauthorized checks. Some of the checks are less than 60 days old. In addition to the reporting deadline ambiguity, we are suspicious about her forgery claims for a number of reasons. What protections does the bank have against paying these claims?

We recommend consulting with bank counsel to clarify the time period for reporting unauthorized transactions defined by your account statement and disclosures.

Under the Uniform Commercial Code (UCC), in most circumstances, you will need to reimburse the customer for the amount of a forged check if the customer alerts you to the forgery with “reasonable promptness” (i.e., within one year of receiving an account statement, or a shorter time period defined by your account agreement).

Additionally, your bank is not obligated to reimburse the customer if the customer’s own negligence substantially contributed to the making of the forgeries, provided your bank exercised ordinary care and acted in good faith when paying the checks. Moreover, if your bank was found to be negligent in paying the checks, it still would be liable only to the extent of its comparative negligence (the degree of fault attributable to the bank).

If your customer alerted the bank about the alleged forgeries outside of 30 days, your bank may be able to refuse reimbursement — but only if the 30 day period applies, and not the 60 or 120 day periods mentioned in your account agreement. Also, if your customer alerted the bank about the alleged forgeries within the required time period, and your bank wishes to refuse reimbursement on other grounds (such as the customer’s negligence), we recommend consulting with bank counsel.
