Under PKPA, jurisdiction in Iowa continues as long as Iowa has jurisdiction under Iowa law, Iowa remains residence of children or of any contestant or Iowa declines to exercise its discretion. PKPA prefers the state which made original decree.
Multiple issues. See summary.
Where a court invokes emergency jurisdiction under PKPA, this jurisdiction continues only for as long as the emergency exists or until a court that has jurisdiction to enter or modify a permanent custody order is apprised of the situation and accepts responsibility. Emergency jurisdiction is merely temporary jurisdiction.
