Lack of uniformity complicates the enforcement process in several ways: (1) It increases the costs of the enforcement action in part because the services of more than one lawyer may be required one in the original forum and one in the State where enforcement is sought; (2) It decreases the certainty of outcome; (3) It can turn enforcement into a long and drawn out procedure. A parent opposed to the provisions of a visitation determination may be able to delay implementation for many months, possibly even years, thereby frustrating not only the other parent, but also the process that led to the issuance of the original court order.

The provisions of Part 3 provide several remedies for the enforcement of a custody determination. First, there is a simple procedure for registering a custody determination in another State. This will allow a party to know in advance whether that State will recognize the party's custody determination. This is extremely important in estimating the risk of the child's non-return when the child is sent on visitation. The provision should prove to be very useful in international custody cases.

Second, the Act provides a swift remedy along the lines of habeas corpus. Time is extremely important in visitation and custody cases. If visitation rights cannot be enforced quickly, they often cannot be enforced at all. This is particularly true if there is a limited time within which visitation can be exercised such as may be the case when one parent has been granted visitation during the winter or spring holiday period. Without speedy consideration and resolution of the enforcement of such visitation rights, the ability to visit may be lost entirely. Similarly, a custodial parent must be able to obtain prompt enforcement when the noncustodial parent refuses to return a child at the end of authorized visitation, particularly when a summer visitation extension will infringe on the school year. A swift enforcement mechanism is desirable for violations of both custody and visitation provisions.

The scope of the enforcing court's inquiry is limited to the issue of whether the decree court had jurisdiction and complied with due process in rendering the original custody decree. No further inquiry is necessary because neither Part 2 nor the PKPA allows an enforcing court to modify a custody determination.

Third, the enforcing court will be able to utilize an extraordinary remedy. If the enforcing court is concerned that the parent, who has physical custody of the child, will flee or harm the child, a warrant to take physical possession of the child is available.

Finally, there is a role for public authorities, such as prosecutors, in the enforcement process. Their involvement will encourage the parties to abide by the terms of the custody determination. If the parties know that public authorities and law enforcement officers are available to help in securing compliance with custody determinations, the parties may be deterred from interfering with the exercise of rights established by court order.

The involvement of public authorities will also prove more effective in remedying violations of custody determinations. Most parties do not have the resources to enforce a custody determination in another jurisdiction. The availability of the public authorities as an enforcement agency will help ensure that this remedy can be made available regardless of income level. In addition, the public authorities may have resources to draw on that are unavailable to the average litigant.

This Act does not authorize the public authorities to be involved in the action leading up to the making of the custody determination, except when requested by the court, when there is a violation of the Hague Convention on the Civil Aspects of International Child Abduction, or when the person holding the child has violated a criminal statute. The Act does not mandate that public authorities be involved in all cases. Not all States, or local authorities, have the funds necessary for an effective custody and visitation enforcement program.
