N.D. Cent. Code § 41-03-37

(6) Subsection (c)(1) is a limitation on subsection (b) in cases in which the claimant is an organization. It is designed to protect the claimant against inadvertent accord and satisfaction. If the claimant is an organization payment of the check might be obtained without notice to the personnel of the organization concerned with the disputed claim. Some business organizations have claims against very large numbers of customers. Examples are department stores, public utilities and the like. These claims are normally paid by checks sent by customers to a designated office at which clerks employed by the claimant or a bank acting for the claimant process the checks and record the amounts paid. If the processing office is not designed to deal with communications extraneous to recording the amount of the check and the account number of the customer, payment of a full satisfaction check can easily be obtained without knowledge by the claimant of the existence of the full satisfaction statement. This is particularly true if the statement is written on the reverse side of the check in the area in which indorsements are usually written. Normally, the clerks of the claimant have no reason to look at the reverse side of checks. Indorsement by the claimant normally is done by mechanical means or there may be no indorsement at all. Section 4-205(a). Subsection (c)(1) allows the claimant to protect itself by advising customers by a conspicuous statement that communications regarding disputed debts must be sent to a particular person, office, or place. The statement must be given to the customer within a reasonable time before the tender is made. This requirement is designed to assure that the customer has reasonable notice that the full satisfaction check must be sent to a particular place. The reasonable time requirement could be satisfied by a notice on the billing statement sent to the customer. If the full satisfaction check is sent to the designated destination and the check is paid, the claim is discharged. If the claimant proves that the check was not received at the designated destination the claim is not discharged unless subsection (d) applies.

(7) Subsection (c)(2) is also designed to prevent inadvertent accord and satisfaction. It can be used by a claimant other than an organization or by a claimant as an alternative to subsection (c)(1). Some organizations may be reluctant to use subsection (c)(1) because it may result in confusion of customers that causes checks to be routinely sent to the special designated person, office, or place. Thus, much of the benefit of rapid processing of checks may be lost. An organization that chooses not to send a notice complying with subsection (c)(1)(i) may prevent an inadvertent accord and satisfaction by complying with subsection (c)(2). If the claimant discovers that it has obtained payment of a full satisfaction check, it may prevent an accord and satisfaction if, within 90 days of the payment of the check, the claimant tenders repayment of the amount of the check to the person against whom the claim is asserted.

(8) Subsection (c) is subject to subsection (d). If a person against whom a claim is asserted proves that the claimant obtained payment of a check known to have been tendered in full satisfaction of the claim by “the claimant or an agent of the claimant having direct responsibility with respect to the disputed obligation,” the claim is discharged even if (i) the check was not sent to the person, office, or place required by a notice complying with subsection (c)(1), or (ii) the claimant tendered repayment of the amount of the check in compliance with subsection (c)(2).

(9) In some cases the disputed claim may have been assigned to a finance company or bank as part of a financing arrangement with respect to accounts receivable. If the account debtor was notified of the assignment, the claimant is the assignee of the account receivable and the “agent of the claimant” in subsection (d) refers to an agent of the assignee.
