2021 Tennessee Code
Part 2 - Issue and Acceptance of Payment Order
§ 47-4A-202. Authorized and Verified Payment Orders

The security procedure is a commercially reasonable method of providing security against unauthorized payment orders; and
The bank proves that it accepted the payment order in good faith and in compliance with the security procedure and any written agreement or instruction of the customer restricting acceptance of payment orders issued in the name of the customer. The bank is not required to follow an instruction that violates a written agreement with the customer or notice of which is not received at a time and in a manner affording the bank a reasonable opportunity to act on it before the payment order is accepted.
The security procedure was chosen by the customer after the bank offered, and the customer refused, a security procedure that was commercially reasonable for that customer; and
The customer expressly agreed in writing to be bound by any payment order, whether or not authorized, issued in its name and accepted by the bank in compliance with the security procedure chosen by the customer.
