The six-month extended home state provision of subsection (a)(1) [Me. cite subsection 1, paragraph A] has been modified slightly from the UCCJA. The UCCJA provided that home state jurisdiction continued for six months when the child had been removed by a person seeking the child's custody or for other reasons and a parent or a person acting as a parent continues to reside in the home State. Under this Act, it is no longer necessary to determine why the child has been removed. The only inquiry relates to the status of the person left behind. This change provides a slightly more refined home state standard than the UCCJA or the PKPA, which also requires a determination that the child has been removed "by a contestant or for other reasons." The scope of the PKPA's provision is theoretically narrower than this Act. However, the phrase "or for other reasons" covers most fact situations where the child is not in the home State and, therefore, the difference has no substantive effect.

In another sense, the six-month extended home state jurisdiction provision is this Act is narrower than the comparable provision in the PKPA. The PKPA's definition of extended home State is more expansive because it applies whenever a "contestant" remains in the home State. That class of individuals has been eliminated in this Act. This Act retains the original UCCJA classification of "parent or person acting as parent" to define who must remain for a State to exercise the six-month extended home state jurisdiction. This eliminates the undesirable jurisdictional determinations which would occur as a result of differing state substantive laws on visitation involving grandparents and others. For example, if State A's law provided that grandparents could obtain visitation with a child after the death of one of the parents, then the grandparents, who would be considered "contestants" under the PKPA, could file a proceeding within six months after the remaining parent moved and have the case heard in State A. However, if State A did not provide that grandparents could seek visitation under such circumstances, the grandparents would not be considered "contestants" and State B where the child acquired a new home State would provide the only forum. This Act bases jurisdiction on the parent and child or person acting as a parent and child relationship without regard to grandparents or other potential seekers of custody or visitation. There is no conflict with the broader provision of the PKPA. The PKPA in § (c)(1) authorizes States to narrow the scope of their jurisdiction.
