Modification of convention child-support order

(A) 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: (1) 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 (2) the foreign tribunal lacks or refuses to exercise jurisdiction to modify its support order or issue a new support order. (B) If a tribunal of this State does not modify a convention child-support order because the order is not recognized in this State, Section 63-17-3945(C) applies.
