Except as otherwise provided in NRS 125A.335, 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 pursuant to paragraph (a) or (b) of subsection 1 of NRS 125A.305 and:
1. The court of the other state determines it no longer has exclusive, continuing jurisdiction pursuant to NRS 125A.315 or that a court of this state would be a more convenient forum pursuant to NRS 125A.365; 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.
