§ 20-4-211 — Modification of a 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:
(i) 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
(ii) 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, W.S. 20-4-208(c) applies.
