N.D. Cent. Code § 40-18.1-14 (2025)
Any individual upon whom any fine or costs, or both, has been imposed for violation of a municipal ordinance may, after hearing, be committed upon order of the court to jail or other place provided by the municipality for the incarceration of offenders until the fine or costs, or both, are fully paid. The court may not commit an individual under this section when the reason for the individual's nonpayment of fines or costs is the individual's indigency. A commitment order issued under this section may not exceed thirty days. As used in this section, 'fine' does not include a fee established under subsection 2 of section 40-05-06.
