A court handling an interstate child custody dispute must consider whether it has jurisdiction to decide the custody case. Three laws provide the answer as to whether a particular court has jurisdiction: the Parental Kidnapping Prevention Act [PKPA], the Uniform Child Jurisdiction and Enforcement Act [UCJEA] and the Uniform Child Custody Jurisdiction Act [UCCJA], which has been enacted in some form in all fifty states and the District of Columbia. The PKPA gives priority to the child's home state (the state where the child lived with at least one parent for six months before the custody petition was filed). If one parent moves with the child to live in a new state, the original state continues to be the home state for an additional six months after the move. The child need not be physically present in the original state for the child custody proceeding to be initiated there by the parent who remained behind. Yes. In all states, custody orders can be modified by a court to further the best interests of the child. Usually, the parent requesting the modification must convince a judge that a substantial change in circumstances affecting the child's welfare has occurred since the original custody order was entered. Under the PKPA, the court that issued the initial custody decree has "continuing jurisdiction" over custody matters, provided that the first state meets three preconditions: (1) it entered its initial custody order in accordance with the Parental Kidnapping Prevention Act; (2) the child or one parent continues to live in the state; and (3) the state's own law allows continuing jurisdiction. If these conditions are met, a parent living in another state who wants to modify the initial custody arrangement must file the modification petition in the first state. The UCCJA provides that dismissal is mandatory where the noncustodial parent violates an existing custody order by refusing to return the child to the custodial parent at the end of the child's period of visitation and then asks the out-of-state court to modify custody. Neither the PKPA, UCJEA nor the UCCJA totally precludes the second state from ever modifying the initial custody order. The PKPA permits the second state to modify the initial custody provision if: (1) the second state has jurisdiction to make a child custody determination and (2) the first state no longer has jurisdiction or has declined to exercise jurisdiction. The remedies available under the UCJEA and UCCJA are unavailing if the left-behind parent is unable to find the abducting parent and the child. For this reason, the PKPA makes the federal Parent Locator Service available to assist local police in locating the abductor. The PKPA also provides that any state that treats parental kidnapping as a felony may enlist the F.B.I.'s assistance under the federal Fugitive Felon Act in locating the abducting parent, provided he or she has left the state. In many states, parental kidnapping (also known as interference with parental custody) is a felony, depending upon the circumstances. In others, it is a felony if the child is taken from the state. However, in most states, there can be no kidnapping unless there is an existing custody order that the parent has intentionally violated. Because many parental kidnappings take place before a final custody decree is entered, a few states have extended criminal sanctions to kidnappings that occur before the final custody decree. Several states also permit the court to assess expenses incurred in returning the child against any person convicted of violating the state's criminal custodial interference law. Parents, although they are subject to the PKPA, remain exempt from criminal sanctions under the general federal kidnapping statute. International parental kidnapping is a federal crime, punishable by a fine and/or imprisonment for up to three years. Once the child has been located, a possible solution to the abduction may be provided by the Hague Convention on the Civil Aspects of International Child Abduction. The Convention is in force in approximately 40 countries, including the United States, Mexico, Canada, and most of Europe. The countries that have signed the Hague Convention have agreed that a child who is habitually a resident in one country and who is removed to or retained in another country in breach of the left-behind parent's custody rights must be promptly returned to the country of the child's habitual residence. However, the Convention is inapplicable if the child has been abducted to a country that has not signed the Convention or the child is sixteen or older. Although there need not be a custody decree to invoke the Convention, the left-behind parent must be able to prove that he or she is exercising a "right of custody" at the time of abduction and that he or she had not given permission for the child to be removed or to be retained in the foreign country beyond a specified, agreed-upon time. In the absence of a formal custody order, custodial rights are determined by state law. It is important to remember that a Hague Convention proceeding is not a custody case. At a hearing under the Hague Convention, the judge's job is to determine only where the custody hearing should take place, not who is entitled to custody of the child. The goal of the Hague Convention is the child's swift return to his or her original country where the custody dispute can then be resolved, if necessary, in that country's courts. Parents are obliged to pay child support whether or not they were ever married. Parents also have an obligation to support all of their children, not just the children who reside with them. Thus, although the noncustodial parent is married to someone else or supporting other children, he or she has a continuing obligation to support the children of a previous marriage or relationship. Yes. As of January 1, 1994, the Family Support Act of 1988 requires that all new child support orders provide for automatically withholding child support payments from the obligated parent's paycheck, regardless of whether or not support payments are late. Federal law permits an exception to immediate withholding if the court finds good cause or if the parents both agree to another arrangement. However, a parent who falls at least one month behind in support payments is subject to withholding even in these cases. Withholding may be used to collect current support payments as well as arrearages. States have the option, under federal law, to apply withholding to income other than wages and to order withholding from bonuses, commissions, retirement benefits, rental or interest income, or unemployment compensation benefits. Yes. States permit a child support order to be modified upward or downward based on proof of a substantial change in the parents' financial circumstances or the child's needs. In addition, federal law requires that child support orders be reviewed every three years unless neither parent requests a review or, in temporary assistance for needy families [TANF] cases, if the review would not be in the child's best interest. However, child support orders may only be modified prospectively. The 1986 Bradley amendment to the federal child support laws effectively bars retroactive modification that would wipe out past-due support obligations. Yes. A parent who willfully refuses to comply with a lawful order of child support, though able to do so, may be held in contempt of court and jailed or fined for a fixed period of time as punishment or for an indefinite period until the child support is paid. As of October 1992, failure to pay child support in the interstate context has become a federal crime. An out-of-state parent who has willfully failed to pay court-ordered child support for at least one year or who is at least $5,000 in arrears may be criminally prosecuted by the local United States attorney. For a first offense, the penalties include a fine and/or a prison sentence of up to six months in prison; for a second offense, the punishment is a fine and/or up to two years in jail. A custodial parent who needs to obtain or enforce a child support order but who cannot find the noncustodial parent may enlist the assistance of a child support enforcement agency run by the state or local government, known as a IV-D agency. This assistance is available to all custodial parents, regardless of whether or not they receive public assistance.

Summary:
Under the U.S. Constitution, Congress has little direct authority to legislate in the field of domestic relations. Generally, state policy guides these decisions. Despite the lack of direct authority to legislate domestic relations issues, Congress continues to enact federal laws that indirectly affect family law questions concerning child custody and support. This report answers questions frequently asked regarding the interplay between federal and state laws governing these areas.
