North Dakota Century Code Title 57. Taxation § 57-45-02. Taxes paid by mortgagees or others having liens

Any person who has a lien by mortgage or otherwise upon any real property that has been sold for taxes or on which the taxes have not been paid, may redeem from such sale, or may pay such taxes and the interest, penalty, and costs thereon, and the receipt of the county treasurer or the certificate of redemption, as the case may be, constitutes an additional lien on such land to the amount therein stated. The amount so paid and the interest thereon at the rate specified in the mortgage or other instrument must be collected with, as part of, and in the same manner as, the amount secured by the original lien.
