Colorado Code
Part 6 - Registration, Enforcement, and Modification of Support Order
§ 14-5-613. Jurisdiction to Modify Child Support Order of Another State When Individual Parties Reside in This State

Source: L. 97: Entire section added, p. 542, § 15, effective July 1. L. 2015: Entire part amended, (HB 15-1198), ch. 173, p. 560, § 31, effective July 1.
COMMENT
It is not unusual for the parties and the child subject to a child-support order to no longer reside in the issuing state, and for the individual parties to have moved to the same new state. The result is that the child-support order remains enforceable, but the issuing tribunal no longer has continuing, exclusive jurisdiction to modify its order. A tribunal of the state of mutual residence of the individual parties has jurisdiction to modify the child-support order and assume continuing, exclusive jurisdiction. Although the individual parties must reside in the forum state, there is no requirement that the child must also reside in the forum state (although the child must have moved from the issuing state).
Finally, because modification of the child-support order when all parties reside in the forum is essentially an intrastate matter, subsection (b) withdraws authority to apply most of the substantive and procedural provisions of UIFSA, i.e., those found in the act other than in Articles 1, 2, and 6. Note the duration of the support obligation is a nonmodifiable aspect of the original controlling order, see Section 611(c)-(d).
