N.D. Cent. Code § 41-02-59

(4) Subsection (3) is concerned with the rights and obligations as between the parties to a sales transaction when payment is made by check. This Article recognizes that the taking of a seemingly solvent party’s check is commercially normal and proper and, if due diligence is exercised in collection, is not to be penalized in any way. The conditional character of the payment under this section refers only to the effect of the transaction “as between the parties” thereto and does not purport to cut into the law of “absolute” and “conditional” payment as applied to such other problems as the discharge of sureties or the responsibilities of a drawee bank which is at the same time an agent for collection.

(5) Under subsection (3) payment by check is defeated if it is not honored upon due presentment. This corresponds to the provisions of article on Commercial Paper. (Section 3-802). But if the seller procures certification of the check instead of cashing it, the buyer is discharged. (Section 3-411).

(6) Where the instrument offered by the buyer is not a payment but a credit instrument such as a note or a check post-dated by even one day, the seller’s acceptance of the instrument insofar as third parties are concerned, amounts to a delivery on credit and his remedies are set forth in the section on buyer’s insolvency. As between the buyer and the seller, however, the matter turns on the present subsection and the section on conditional delivery and subsequent dishonor of the instrument gives the seller rights on it as well as for breach of the contract for sale.
