N.D. Cent. Code § 32-12.1-05
An insurance policy or insurance contract purchased by a political subdivision or a government self-insurance pool in which a political subdivision participates pursuant to this chapter may provide coverage for the types of liabilities established by this chapter and may provide such additional coverage as the governing body of the political subdivision determines to be appropriate. The insurer may not assert the defense of governmental immunity, but this chapter confers no right upon a claimant to sue an insurer directly. If a dispute exists concerning the amount or nature of the required insurance coverage, the dispute must be tried separately. The insurance coverage authorized by this chapter may be in addition to any insurance coverage purchased by a political subdivision pursuant to any other provision of law and if premium savings will result therefrom, any insurance policy purchased pursuant to this chapter or any other provision of law may be written for a period which exceeds one year.
