Okla. Stat. tit. 12A, § 4A-405
Oklahoma Code Comment
The beneficiary's bank may not agree to pay the beneficiary while reserving the right to recover the payment if it does not get paid unless an enforceable funds transfer system rule so provides.
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.
