§ 336.4A-204 — Refund of Payment and Duty of Customer to Report With Respect to Unauthorized Payment Order

Plain-Language Summary

If a bank accepts a payment order issued in the customer's name that was not authorized by the customer or is not enforceable against the customer, the bank must refund any payment it received from the customer that it is not entitled to keep, plus interest from the date it received the payment to the date of the refund. The customer loses the right to that interest (but not the refund itself) if the customer fails to use ordinary care to discover the unauthorized order and notify the bank within a reasonable time, not to exceed 90 days after the customer was notified that the order was accepted or the account was debited. The parties may set what counts as a reasonable time by agreement, but the bank's basic duty to refund cannot otherwise be changed by agreement.

Practical Notes
If your bank pays out on a wire transfer that you did not authorize, the bank generally must give your money back with interest. To keep the interest, you need to catch the problem with ordinary care and tell the bank within a reasonable time (no more than 90 days after notice that the order was paid or your account was charged); missing that window costs you only the interest, not the refund.
