N.D. Cent. Code § 61-09-15
All assessments made pursuant to the provisions of this chapter on real property, and assessments on leasehold estates owned by this state or any of its subdivisions, and, to the extent provided by the Act of Congress of August 11, 1916, assessments on entered or unentered public lands shall be a general tax against the real property on which assessed in like manner and to the same effect as general state and county taxes and shall be of the same order. The lien thereof shall share ratably with general tax liens in all tax proceedings and tax lien foreclosures and shall be subject to all provisions of law relating to general taxes. Such assessment shall become due and payable and delinquent at the same time as other general state and county taxes lien foreclosure and shall remain subject to all statutory provisions applying to tax lien foreclosure. In case leasehold estates only are affected by said assessments, the tax lien foreclosure notice shall state that fact. The lien for the bonds of any series shall be preferred to that of any subsequent series, and the lien for the payments due to the United States under any contract between the district and the United States, accompanying which bonds have not been deposited with the United States, shall be a lien preferred over that of any issue of bonds or any series of any issue subsequent to the date of such contract. All funds arising from assessment and levy, if any, shall be devoted to the obligations of the district payable from said funds and as to all obligations from the bond and United States contract a fund shall be so devoted in the order of priority of the creation of the obligation. No error or omission which may be made in the proceedings of the board, or of any officer of an irrigation district in referring, reporting upon, ordering or otherwise acting concerning the establishment, construction, or acquisition of irrigation works, or concerning the issuance of bonds or improvement warrants, or in making or certifying any assessment shall vitiate or in any way affect any such assessment; but if it shall appear that by reason of such error or omission substantial injury has been done to the party or parties claiming to be aggrieved, the court shall alter such assessment as may be just and the same shall then be enforced. Whenever the validity of any assessment, or the validity of any deed given pursuant to a foreclosure of tax lien for such assessment shall be drawn in question in any action in any district court in this state, and such assessment shall be held to be invalid by reason of noncompliance with the laws of this state, the court shall determine the true and just amount which the property attempted to be so assessed by said assessment should pay, to make the same uniform with other assessments for the same purpose, and the amount of such assessments as the same appears on the assessment list thereof, shall be prima facie evidence of such true and just amount, and judgment must be rendered and given therefor against the property liable for such assessment, without regard to the proceedings had for the levy thereof, and such judgment shall be a lien upon the property upon which the assessment shall have been levied, of equal force and effect as the lien of irrigation district assessments, and the lien of such judgment shall be enforced by the court in such action.
