By contrast, a country such as Australia has a custody registration system that operates in a very similar way to the system of registration of foreign custody orders in the Uniform Child Custody Jurisdiction & Enforcement Act. However, Australia is very much the exception rather than the rule. The European Union has a registration system but it applies only to orders issued by an E.U. court and the practice within Europe varies substantially from country to country.
Indeed, foreign lawyers are generally shocked and amazed when they learn of the registration provisions in the UCCJEA. In particular, they are often shocked that a U.S. court will generally have exclusive continuing jurisdiction for many years after a child has left the jurisdiction as long as one parent continues to live there. The issue was recently before the Court of Appeal in England. (5) Since that Court is headed by a judge who is also that country's "Head of International Family Law" its decisions on such issues are far less like to be parochial than similar rulings from some courts in the United States and many other countries.

(6). An example of a critical factor that is often overlooked is that a visit to one country may permit an easy visit to another country. Thus, once a child is in any European country that is within the "Schengen Zone" the child may be taken to any other such country without passing through any passport control.
