A party or support enforcement agency seeking to modify, or to modify and enforce, a foreign child support order not under the Convention may register that order in this state under sections 14-5-601 through 14-5-608 if the order has not been registered. A petition for modification may be filed at the same time as a request for registration, or at another time. The petition must specify the grounds for modification.L. 2015: Entire part amended, (HB 15-1198), ch. 173, p. 561, § 31, effective July 1.COMMENTThe procedure for registration and enforcement set forth in Sections 601 through 608 is applicable to a child-support order from a non-Convention country. This section provides coverage for modification in that situation. Presumptively, the general law of the state regarding modification of a child-support order will apply because, by their terms, Sections 609 through 614 apply only to modification of a child-support order by a state tribunal. The rationale is that modification is available because the foreign order is not founded on the UIFSA principles of continuing, exclusive jurisdiction and a controlling order. See Sections 205 through 207.
