Okla. Stat. tit. 12A, § 4A-501
Oklahoma Code Comment
This section sets forth the rule which governs sections permitting the amendment of the rules of Article 4A. It allows a party to a funds transfer to vary its rights and obligations by agreement unless "otherwise provided in this Article."
A funds transfer system rule may modify the obligations of members of the system. A "funds transfer system" means a communications system of an association of banks through which a payment order may be transmitted to the bank to which the order is addressed. § 4A-105(a)(5). It may only affect nonmembers to the following extent:
1. The right of a beneficiary to be notified of the receipt of an order may be modified by funds transfer system rule if the beneficiary is notified of the rule before initiation of the transfer. §4A-404(c).
2. Provisional settlement with the beneficiary may be given effect by funds transfer system rule only if the rule requires that the beneficiary and originator be given notice of the rule before the transfer is originated and the beneficiary, the beneficiary's bank and the originator's bank agree to be bound by the rule. §4A-405(d).
3. A funds transfer system may bind participants to a choice-of-law rule. It may only bind non-participants only if they know that the system may be used and they have been informed of the rule prior to the initiation of the transfer. §4A-507(a). If the receiving bank is obligated to pay interest, the rate may be set by agreement between the sender and the receiving bank.
