Interstate Child Custody Lawyer in San Francisco
Strategic Representation in UCCJEA Jurisdiction, Interstate Custody Disputes, and International Family Law
When parents reside in different states or countries, a child custody dispute may involve more than determining which parent should have custody. The first and often most consequential question is which court has legal authority to decide the matter.
The Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA) governs jurisdiction in interstate custody disputes and provides a framework for recognizing and enforcing qualifying custody determinations across state lines. Its application can become particularly complex when a child relocates, custody proceedings are pending elsewhere, or an existing order was issued by another state or foreign court.
At Multi-Jurisdictional Divorce (MJD), we represent parents in sophisticated interstate and international custody matters involving San Francisco, California, and jurisdictions throughout the United States and abroad. Our approach combines jurisdictional analysis, litigation strategy, and practical consideration of whether a custody determination can be enforced where the child actually resides.

Understanding the UCCJEA: Which Court Has Jurisdiction?
One of the most common misconceptions in interstate custody litigation is that a parent may establish jurisdiction simply by moving to another state and commencing proceedings there.
The law is considerably more complex.
California Family Code §§ 3400–3465 incorporate the UCCJEA, which establishes rules for determining the appropriate forum for initial custody proceedings, modification of existing orders, and enforcement of qualifying determinations.
The governing questions may include:
Where has the child actually lived during the relevant period?
Which state qualifies as the child’s home state?
Has another court already entered a custody determination?
Does the original court retain exclusive, continuing jurisdiction?
Are simultaneous proceedings pending in different jurisdictions?
Does an emergency justify temporary intervention by a California court?
Is there a qualifying foreign custody determination requiring recognition or enforcement?
A California court’s authority cannot ordinarily be created merely through a parent’s preference, agreement, or physical presence in the state.
Identifying the correct forum before initiating litigation is therefore essential.
Home-State Jurisdiction and Interstate Relocation
Under California Family Code § 3421, a child’s home state generally receives priority when determining jurisdiction over an initial custody proceeding.
For a child at least six months old, the home-state analysis ordinarily examines where the child lived with a parent or person acting as a parent for six consecutive months immediately before the proceeding commenced, including applicable periods of temporary absence.
However, the analysis does not end with the child’s current address.
A state may remain the child’s recent home state after relocation, and other jurisdictional grounds may become relevant when no state qualifies or the appropriate court declines jurisdiction.
For example, a parent who relocates with a child from New York to San Francisco may incorrectly assume that California immediately becomes the appropriate forum for custody litigation.
Depending on the child’s residence history and existing proceedings, New York may continue to have jurisdiction.
Relocation does not automatically transfer custody jurisdiction.
Existing Custody Orders and Exclusive, Continuing Jurisdiction
When a custody order has already been issued in another state, modification of that order is subject to additional statutory restrictions.
California Family Code §§ 3422 and 3423 address exclusive, continuing jurisdiction and the circumstances under which California may modify another state’s custody determination.
The original court may retain authority notwithstanding the child’s subsequent relocation. Conversely, changes in the parties’ residences and the location of relevant evidence may ultimately affect that jurisdiction.
These questions must be examined before filing a modification request.
An attempt to modify an existing order in an unauthorized forum can result in dismissal, conflicting litigation, or substantial delay.
At MJD, we evaluate the jurisdictional history of the matter, the controlling orders, and the available procedural remedies before recommending a course of action.
Enforcement of Out-of-State Custody Orders in California
Parents may also need to enforce an existing custody or visitation order when the other parent relocates to California or refuses to comply with an order issued elsewhere.
The UCCJEA provides procedures for recognition, registration, and enforcement of qualifying custody determinations.
Depending on the circumstances, relief may involve:
Registration of an out-of-state custody order.
Enforcement of custody and parenting-time provisions.
Proceedings concerning wrongful retention or interference with custodial rights.
Expedited enforcement where statutory requirements are satisfied.
Coordination with the court that issued the original order.
Enforcement and modification are distinct legal remedies. A California court may possess authority to enforce an existing order without having jurisdiction to change its terms.
Mediation Is Often Required — and Invaluable
In many jurisdictions under the UCCJEA, child custody mediation is a required first step. This process, again, centers on what’s best for the child—not the parents. Both parties are expected to make a genuine effort to cooperate and reach an agreement, often with the guidance of a neutral, trained custody mediator.
If mediation fails, the family court will step in to determine custody, possibly limiting a parent’s ability to make decisions about their child’s upbringing. In these situations, an experienced interstate child custody mediator can be critical to preserving joint parenting authority.
Temporary Emergency Custody Jurisdiction in California
California Family Code § 3424 permits temporary emergency jurisdiction in specified circumstances involving a child physically present in California who requires protection because of abandonment, mistreatment, or abuse.
Emergency jurisdiction serves an important protective function, but it is not an unrestricted alternative to the authority of the child’s home-state court.
Where another court has previously entered a custody order or proceedings remain pending elsewhere, California’s emergency jurisdiction is subject to statutory limitations and coordination requirements.
Urgent legal intervention therefore requires careful attention to the underlying facts, existing orders, and the precise relief being requested.
Interstate Custody and International Child Abduction
International custody disputes may involve both the UCCJEA and the Hague Convention on the Civil Aspects of International Child Abduction.
Although these legal frameworks may intersect, they serve different purposes.
The UCCJEA primarily determines which court may exercise custody jurisdiction and establishes procedures for recognizing and enforcing qualifying custody orders.
The Hague Convention may provide a remedy for the return of a child under 16 who has been wrongfully removed from or retained outside the child’s country of habitual residence, provided the applicable treaty requirements are satisfied.
A Hague Convention proceeding does not ordinarily determine the ultimate custody rights of the parents.
California Family Code § 3405 also addresses the treatment of foreign countries and qualifying foreign custody determinations under specified UCCJEA provisions, subject to statutory limitations.
In international cases, counsel must examine both the available remedies and the relationship between proceedings in different jurisdictions.
International Relocation and Competing Custody Proceedings
A relocation agreement that appears appropriate when signed may create substantial legal difficulties years later.
A child may establish a permanent life abroad while one parent continues to reside in the United States. The original court may retain jurisdiction under domestic law, while a foreign court may apply entirely different jurisdictional principles.
These circumstances raise significant questions concerning:
Continuing jurisdiction after international relocation.
The legal effect of forum-selection provisions.
Recognition of foreign custody judgments.
Simultaneous proceedings in multiple countries.
International enforcement of parenting arrangements.
Potential Hague Convention remedies.
The decision in Hogan v. McAndrew, 131 A.3d 717 (R.I. 2016), illustrates the importance of a proper statutory analysis before a court declines jurisdiction in favor of a foreign forum.
Although not binding California authority, the case demonstrates why international relocation agreements should anticipate potential jurisdictional disputes rather than rely solely on the parents’ original intentions.
Why Work With Multi-Jurisdictional Divorce?
Interstate custody litigation is fundamentally different from a custody dispute confined to a single jurisdiction.
A successful strategy requires understanding not only the substantive custody issues but also the limitations on each court’s authority.
Elena Giannattasio, Founder and Managing Attorney of Multi-Jurisdictional Divorce and a Fellow of the International Academy of Family Lawyers, advises clients on jurisdictional disputes involving California, other U.S. states, and foreign countries.
Our practice includes UCCJEA litigation, recognition and enforcement of custody orders, jurisdictional challenges, international relocation issues, and matters involving the Hague Child Abduction Convention.
Where appropriate, we coordinate with qualified counsel in other jurisdictions to develop legally coherent and practically enforceable solutions.
In interstate and international custody litigation, determining the appropriate jurisdiction is not a preliminary technicality. It can determine the entire course of the litigation.
I have seen how parents may become involved in proceedings before different courts, each operating under distinct legal rules, while the child's residence and circumstances continue to evolve.
A custody order is of limited practical value if the issuing court lacked jurisdiction or if the order cannot be recognized or enforced where the child resides.
For that reason, I approach multi-jurisdictional custody disputes by examining three fundamental questions: Which court has authority? What relief may that court lawfully grant? And will the resulting determination be enforceable in the jurisdiction where it matters?
Effective representation requires anticipating these issues before they become obstacles to protecting the child's interests.
