The phrase "do not presently reside" is not used in the sense of a technical domicile. The fact that the original determination State still considers one parent a domiciliary does not prevent it from losing exclusive, continuing jurisdiction after the child, the parents, and all persons acting as parents have moved from the State.

If the child, the parents, and all persons acting as parents have all left the State which made the custody determination prior to the commencement of the modification proceeding, considerations of waste of resources dictate that a court in State B, as well as a court in State A, can decide that State A has lost exclusive, continuing jurisdiction.

The continuing jurisdiction provisions of this section are narrower than the comparable provisions of the PKPA. That statute authorizes continuing jurisdiction so long as any "contestant" remains in the original decree State and that State continues to have jurisdiction under its own law. This Act eliminates the contestant classification. The Conference decided that a remaining grandparent or other third party who claims a right to visitation, should not suffice to confer exclusive, continuing jurisdiction on the State that made the original custody determination after the departure of the child, the parents and any person acting as a parent. The significant connection to the original decree State must relate to the child, the child and a parent, or the child and a person acting as a parent. This revision does not present a conflict with the PKPA. The PKPA's reference in § 1738(d) to § 1738(c)(1)
