RCW 26.21A.625: Modification of convention child support order.

(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, RCW 26.21A.617(3) applies.
