2021 Colorado Code|Title 4 - Uniform Commercial Code|Article 4.5 - Funds Transfers|Part 4 - Payment|§ 4-4.5-402. Obligation of Sender to Pay Receiving Bank

  This section is subject to sections 4-4.5-205 and 4-4.5-207.    With respect to a payment order issued to the beneficiary's bank, acceptance of the order by the bank obliges the sender to pay the bank the amount of the order, but payment is not due until the payment date of the order.    This subsection (c) is subject to subsection (e) of this section and to section 4-4.5-303. With respect to a payment order issued to a receiving bank other than the beneficiary's bank, acceptance of the order by the receiving bank obliges the sender to pay the bank the amount of the sender's order. Payment by the sender is not due until the execution date of the sender's order. The obligation of that sender to pay its payment order is excused if the funds transfer is not completed by acceptance by the beneficiary's bank of a payment order instructing payment to the beneficiary of that sender's payment order.    If the sender of a payment order pays the order and was not obliged to pay all or part of the amount paid, the bank receiving payment is obliged to refund payment to the extent the sender was not obliged to pay. Except as provided in sections 4-4.5-204 and 4-4.5-304, interest is payable on the refundable amount from the date of payment.    If a funds transfer is not completed as stated in subsection (c) of this section and an intermediary bank is obliged to refund payment as stated in subsection (d) of this section but is unable to do so because not permitted by applicable law or because the bank suspends payments, a sender in the funds transfer that executed a payment order in compliance with an instruction, as stated in section 4-4.5-302(a)(1), to route the funds transfer through that intermediary bank is entitled to receive or retain payment from the sender of the payment order that it accepted. The first sender in the funds transfer that issued an instruction requiring routing through that intermediary bank is subrogated to the right of the bank that paid the intermediary bank to refund as stated in subsection (d) of this section.    The right of the sender of a payment order to be excused from the obligation to pay the order as stated in subsection (c) of this section or to receive refund under subsection (d) of this section may not be varied by agreement.     History. Source: L. 90: Entire article added, p. 356, § 1, effective January 1, 1991.    OFFICIAL COMMENT   1. Subsection (b) states that the sender of a payment order to the beneficiary's bank must pay the order when the beneficiary's bank accepts the order. At that point the beneficiary's bank is obliged to pay the beneficiary. Section 4A-404(a). The last clause of subsection (b) covers a case of premature acceptance by the beneficiary's bank. In some funds transfers, notably automated clearing house transfers, a beneficiary's bank may receive a payment order with a payment date after the day the order is received. The beneficiary's bank might accept the order before the payment date by notifying the beneficiary of receipt of the order. Although the acceptance obliges the beneficiary's bank to pay the beneficiary, payment is not due until the payment date. The last clause of subsection (b) is consistent with that result. The beneficiary's bank is also not entitled to payment from the sender until the payment date.   2. Assume that Originator instructs Bank A to order immediate payment to the account of Beneficiary in Bank B. Execution of Originator's payment order by Bank A is acceptance under Section 4A-209(a), Under the second sentence of Section 4A-402(c) the acceptance creates an obligation of Originator to pay Bank A the amount of the order. The last clause of that sentence deals with attempted funds transfers that are not completed. In that event the obligation of the sender to pay its payment order is excused. Originator makes payment to Beneficiary when Bank B, the beneficiary's bank, accepts a payment order for the benefit of Beneficiary. Section 4A-406(a). If that acceptance by Bank B does not occur, the funds transfer has miscarried because Originator has not paid Beneficiary. Originator doesn't have to pay its payment order, and if it has already paid it is entitled to refund of the payment with interest. The rate of interest is stated in Section 4A-506. This “money-back guarantee” is an important protection of Originator. Originator is assured that it will not lose its money if something goes wrong in the transfer. For example, risk of loss resulting from payment to the wrong beneficiary is borne by some bank, not by Originator. The most likely reason for noncompletion is a failure to execute or an erroneous execution of a payment order by Bank A or an intermediary bank. Bank A may have issued its payment order to the wrong bank or it may have identified the wrong beneficiary in its order. The money-back guarantee is particularly important to Originator if noncompletion of the funds transfer is due to the fault of an intermediary bank rather than Bank A. In that case Bank A must refund payment to Originator, and Bank A has the burden of obtaining refund from the intermediary bank that it paid.   Subsection (c) can result in loss if an intermediary bank suspends payments. Suppose Originator instructs Bank A to pay to Beneficiary's account in Bank B and to use Bank C as an intermediary bank. Bank A executes Originator's order by issuing a payment order to Bank C. Bank A pays Bank C. Bank C fails to execute the order of Bank A and suspends payments. Under subsections (c) and (d), Originator is not obliged to pay Bank A and is entitled to refund from Bank A of any payment that it may have made. Bank A is entitled to a refund from Bank C, but Bank C is insolvent. Subsection (e) deals with this case. Bank A was required to issue its payment order to Bank C because Bank C was designated as an intermediary bank by Originator. Section 4A-302(a)(1). In this case Originator takes the risk of insolvency of Bank C. Under subsection (e) Bank A is entitled to payment from Originator and Originator is subrogated to the right of Bank A under subsection (d) to refund of payment from Bank C.   3. A payment order is not like a negotiable instrument on which the drawer or maker has liability. Acceptance of the order by the receiving bank creates an obligation of the sender to pay the receiving bank the amount of the order. That is the extent of the sender's liability to the receiving bank and no other person has any rights against the sender with respect to the sender's order.
