C.R.S. § 14-13-203
This section is similar to former § 14-13-115 as it existed prior to 2000.
OFFICIAL COMMENT
This section complements Section 14-13-202 and is addressed to the court that is confronted with a proceeding to modify a custody determination of another State. It prohibits a court from modifying a custody determination made consistently with this Act by a court in another State unless a court of that State determines that it no longer has exclusive, continuing jurisdiction under Section 14-13-202 or that this State would be a more convenient forum under Section 14-13-207. The modification State is not authorized to determine that the original decree State has lost its jurisdiction. The only exception is when the child, the child's parents, and any person acting as a parent do not presently reside in the other State. In other words, a court of the modification State can determine that all parties have moved away from the original State. The court of the modification State must have jurisdiction under the standards of Section 14-13-201.
