N.D. Cent. Code § 27-01-09
The district courts shall recognize and cause to be enforced any judgment, decree, or order of the tribal court of the Three Affiliated Tribes of the Fort Berthold Reservation in any case involving the dissolution of marriage, the distribution of property upon divorce, child custody, adoption, an adult abuse protection order, or an adjudication of the delinquency, dependency, or neglect of Indian children if the tribal court had jurisdiction over the subject matter of the judgment, decree, or order. The tribal court judgment, decree, or order must be rendered by a judge who is a graduate of an accredited law school and holds a current valid license to practice law in at least one state. A state court may inquire as to the facts of the case or tribal law only to the extent necessary to determine whether the tribal court had jurisdiction over the subject matter of the judgment, decree, or order and personal jurisdiction over the parties to the action. Recognition and enforcement of tribal court judgments, decrees, and orders under this section is conditioned upon recognition and enforcement of state court judgments, decrees, and orders by the tribal court of the Three Affiliated Tribes and tribal law enforcement agencies under the same limitations provided by this section for recognition and enforcement of tribal court judgments, decrees, and orders by state courts.
