§ 76-b. Jurisdiction to modify determination. Except as otherwise provided in section seventy-six-c of this title, a court of this state may not modify a child custody determination made by a court of another state unless a court of this state has jurisdiction to make an initial determination under paragraph (a) or (b) of subdivision one of section seventy-six of this title and:

1. The court of the other state determines it no longer has exclusive, continuing jurisdiction under section seventy-six-a of this title or that a court of this state would be a more convenient forum under section seventy-six-f of this title; or

2. A court of this state or a court of the other state determines that the child, the child's parents, and any person acting as a parent do not presently reside in the other state.
