N.D. Cent. Code § 11-28.3-13
The boundaries of any rural ambulance service district organized under this chapter may be changed in the manner prescribed by section 11-28.3-15 or 11-28.3-16, but a change in the boundary of a district does not impair or affect its organization or its right in or to property; nor does it impair, affect, or discharge any contract, obligation, lien, or charge for or upon which it might be liable had such change of boundaries not been made.
Dissolution of a rural ambulance service district may be accomplished as provided in this section. If an ambulance service district in whole does not provide emergency medical services under section 23-27-01, whether directly or through a contract under section 11-28.3-12, the district board, upon its own motion and vote, may dissolve the district effective the subsequent tax year. The territory remains subject to all debts and obligations of the dissolved district pursuant to the procedure under section 11-28.3-17. Any funds remaining after all debts and obligations are paid must be divided among those rural ambulance service districts or political subdivisions responsible for emergency medical service operations in the jurisdiction in the same proportion as the geographical area of the district.
