The Hague Convention on the Civil Aspects of International Child Abduction

The Hague Convention only applies between countries that have ratified it.

Child custody jurisdiction disputes between U.S. states and non-ratifying countries are governed by the Uniform Child Custody Jurisdiction Act or Uniform Child Custody Jurisdiction and Enforcement Act of the U.S. state in question, which also is relevant even to Hague-ratifying countries once there are no further Hague Convention questions to be decided.
