Okla. Stat. tit. 12A, § 12A-4A-501: Variation by agreement and effect of funds-transfer

system rule.

VARIATION BY AGREEMENT AND EFFECT OF FUNDS-TRANSFER SYSTEM RULE

(a) Except as otherwise provided in this Article, the rights

and obligations of a party to a funds transfer may be varied by

agreement of the affected party.

(b) "Funds-transfer system rule" means a rule of an association

of banks (i) governing transmission of payment orders by means of a

funds-transfer system of the association or rights and obligations

with respect to those orders, or (ii) to the extent the rule governs

rights and obligations between banks that are parties to a funds

transfer in which a Federal Reserve Bank, acting as an intermediary

bank, sends a payment order to the beneficiary's bank. Except as

otherwise provided in this Article, a funds-transfer system rule

governing rights and obligations between participating banks using

the system may be effective even if the rule conflicts with this

Article and indirectly affects another party to the funds transfer

who does not consent to the rule. A funds-transfer system rule may

also govern rights and obligations of parties other than

participating banks using the system to the extent stated in

subsection (c) of Section 29, subsection (d) of Section 30, and

subsection (c) of Section 38 of this act.
