Modification of Convention child support order.

1. (a) A tribunal of the commonwealth 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. (1) the obligee submits to the jurisdiction of a tribunal of the commonwealth, either expressly or by defending on the merits of the case without objecting to the jurisdiction at the first available opportunity; or
   2. (2) the foreign tribunal lacks or refuses to exercise jurisdiction to modify its support order or issue a new support order.
2. (b) If a tribunal of the commonwealth does not modify a Convention child support order because the order is not recognized in the commonwealth, section 7–708(c) applies.
