N.D. Cent. Code § 4.1-20-16
Any individual running for the office of supervisor shall present to the county auditor of the county in which the district lies a petition giving that individual's name and mailing address and the title and term of the office, and containing the signatures of not less than twenty-five nor more than three hundred qualified electors of the district. When a district lies in more than one county, the petition must be filed with the county auditor of the county where the candidate resides, and that county auditor shall certify to the county auditors of the other counties in which the district lies the name and mailing address of the candidate filing such petition. At the same time, the county auditor, or auditors in the case of multicounty districts, also shall certify to the secretary of state the name and mailing address of each individual filing a nominating petition according to this section. An individual may not participate directly or indirectly in the nomination for more than one individual for each office to be filled. The final filing date for nominating petitions is no later than four p.m. sixty-four days before the day of the election.
Upon receipt of the petition or the certification as provided in this section, the county auditor shall place, without fee, the name of the candidate so nominated on the no-party ballot at the ensuing general election.
