Colorado Code
Part 2 - Issue and Acceptance of Payment Order
§ 4-4.5-207. Misdescription of Beneficiary

(1) If the originator is a bank, the originator is obliged to pay its order.
(2) If the originator is not a bank and proves that the person identified by number was not entitled to receive payment from the originator, the originator is not obliged to pay its order unless the originator's bank proves that the originator, before acceptance of the originator's order, had notice that payment of a payment order issued by the originator might be made by the beneficiary's bank on the basis of an identifying or bank account number even if it identifies a person different from the named beneficiary. Proof of notice may be made by any admissible evidence. The originator's bank satisfies the burden of proof if it proves that the originator, before the payment order was accepted, signed a writing stating the information to which the notice relates.

(1) If the originator is obliged to pay its payment order as stated in subsection (c) of this section, the originator has the right to recover.
(2) If the originator is not a bank and is not obliged to pay its payment order, the originator's bank has the right to recover.

Although the clear trend is for beneficiary's banks to process payment orders by automated means, Section 4A-207 is not limited to cases in which processing is done by automated means. A bank that processes by semi-automated means or even manually may rely on number as stated in Section 4A-207.
In cases covered by subsection (b) the erroneous identification would in virtually all cases be the identifying or bank account number. In the typical case the error is made by the originator of the funds transfer. The originator should know the name of the person who is to receive payment and can further identify that person by an address that would normally be known to the originator. It is not unlikely, however, that the originator may not be sure whether the identifying or account number refers to the person the originator intends to pay. Subsection (b)(1) deals with the typical case in which the beneficiary's bank pays on the basis of the account number and is not aware at the time of payment that the named beneficiary is not the holder of the account which was paid. In some cases the false number will be the result of error by the originator. In other cases fraud is involved. For example, Doe is the holder of shares in Mutual Fund. Thief, impersonating Doe, requests redemption of the shares and directs Mutual Fund to wire the redemption proceeds to Doe's account #12345 in Beneficiary's Bank. Mutual Fund originates a funds transfer by issuing a payment order to Originator's Bank to make the payment to Doe's account #12345 in Beneficiary's Bank. Originator's Bank executes the order by issuing a conforming payment order to Beneficiary's Bank which makes payment to account #12345. That account is the account of Roe rather than Doe. Roe might be a person acting in concert with Thief or Roe might be an innocent third party. Assume that Roe is a gem merchant that agreed to sell gems to Thief who agreed to wire the purchase price to Roe's account in Beneficiary's Bank. Roe believed that the credit to Roe's account was a transfer of funds from Thief and released the gems to Thief in good faith in reliance on the payment. The case law is unclear on the responsibility of a beneficiary's bank in carrying out a payment order in which the identification of the beneficiary by name and number is conflicting. See Securities Fund Services, Inc. v. American National Bank, 542 F. Supp. 323 (N.D.Ill. 1982) and Bradford Trust Co. v. Texas American Bank, 790 F.2d 407 (5th Cir. 1986). Section 4A-207 resolves the issue.
If Beneficiary's Bank did not know about the conflict between the name and number, subsection (b)(1) applies. Beneficiary's Bank has no duty to determine whether there is a conflict and it may rely on the number as the proper identification of the beneficiary of the order. When it accepts the order, it is entitled to payment from Originator's Bank. Section 4A-402(b). On the other hand, if Beneficiary's Bank knew about the conflict between the name and number and nevertheless paid Roe, subsection (b)(2) applies. Under that provision, acceptance of the payment order of Originator's Bank did not occur because there is no beneficiary of that order. Since acceptance did not occur Originator's Bank is not obliged to pay Beneficiary's Bank. Section 4A-402(b). Similarly, Mutual Fund is excused from its obligation to pay Originator's Bank. Section 4A-402(c). Thus, Beneficiary's Bank takes the loss. Its only cause of action is against Thief. Roe is not obliged to return the payment to the beneficiary's bank because Roe received the payment in good faith and for value. Article 4A makes irrelevant the issue of whether Mutual Fund was or was not negligent in issuing its payment order.
In the hypothetical case if Originator's Bank made the disclosure stated in the last sentence of subsection (c)(2), Mutual Fund must pay Originator's Bank. Under subsection (d)(1), Mutual Fund has an action to recover from Roe if recovery from Roe is permitted by the law governing mistake and restitution. Under the assumed facts Roe should be entitled to keep the money as a person who took it in good faith and for value since it was taken as payment for the gems. In that case, Mutual Fund's only remedy is against Thief. If Roe was not acting in good faith, Roe has to return the money to Mutual Fund. If Originator's Bank does not prove that Mutual Fund had notice as stated in subsection (c)(2), Mutual Fund is not required to pay Originator's Bank. Thus, the risk of loss falls on Originator's Bank whose remedy is against Roe or Thief as stated above. Subsection (d)(2).
