Okla. Stat. tit. 12A, § 4A-205
Oklahoma Code Comment
With respect to Official Comment 1, Oklahoma law supports the result in Case # 1, Case # 2 and Case # 3 that the sender's remedy is from the beneficiary who received payment. See the introductory comment as to the Oklahoma law on mistake and restitution. If an error is not detected, some beneficiary will receive funds that the beneficiary was not intended to receive and the risk of loss with respect to the error of the sender is shifted to the bank, which has the burden of recovering the funds from the beneficiary. A receiving bank to which the risk of loss is shifted by subsections (2) and (3) should be entitled under existing Oklahoma law to recover the amount erroneously paid to the beneficiary.
With respect to Official Comment 2, existing Oklahoma law is silent on this point except by analogy to Article 4 of the Uniform Commercial Code.
For discussion of cases decided under law prior to Article 4A concerning erroneous orders and how Article 4A would resolve these issues, Bee the discussion of the Walker and Banque Worms cases in the introductory comment.
