Part 3 - Execution of Sender's Payment Order by Receiving Bank
§ 47-4A-302. Obligations of Receiving Bank in Execution of Payment Order

If the originator's bank issues a payment order to an intermediary bank, the originator's bank is obliged to instruct the intermediary bank according to the instruction of the originator. An intermediary bank in the funds transfer is similarly bound by an instruction given to it by the sender of the payment order it accepts.
A receiving bank is not required to follow an instruction of the sender designating a funds-transfer system to be used in carrying out the funds transfer if the receiving bank, in good faith, determines that it is not feasible to follow the instruction or that following the instruction would unduly delay completion of the funds transfer.
Any intermediary bank or funds-transfer system to be used in carrying out the funds transfer; or
The means by which payment orders are to be transmitted in the funds transfer.
