N.D. Cent. Code § 14-12.2-47.11 (2025)
1. A tribunal of this state may not modify a convention child support order if the obligee remains a resident of the foreign country where the support order was issued unless: a. The obligee submits to the jurisdiction of a tribunal of this state, either expressly or by defending on the merits of the case without objecting to the jurisdiction at the first available opportunity; or b. The foreign tribunal lacks or refuses to exercise jurisdiction to modify its support order or issue a new support order.
2. If a tribunal of this state does not modify a convention child support order because the order is not recognized in this state, subsection 3 of section 14-12.2-47.8 applies.
