N.D. Cent. Code § 57-22-13.1
No security interest in or other lien upon personal property is foreclosed by the sale of such property unless the secured party, the secured party's agent or attorney, or the editor or publisher of the printing concern or company which prints such foreclosure notice, at least five days before the date of such sale, has mailed or delivered to the county treasurer of the county in which the sale is to be held a copy of such notice of foreclosure sale. The notice must be mailed to the county treasurer by registered or certified mail and must contain a list of the personal property to be sold, with the name and address of the owners of such property. An affidavit reciting the mailing or delivery of such notice to the county treasurer must be filed with the report of sale required to be filed in the office of the recorder, and no such foreclosure sale is valid unless such notice of sale has been mailed or delivered to the county treasurer as herein provided.
