Custody Disputes Across State and Country Lines: Our Experience with UCCJEA and Complex Jurisdictional Cases

Co-Authored by Cynthia L. Best, Esq. & Tali Best Collins, Esq.

Custody disputes are difficult under any circumstances. They become significantly more complex when parents live in different states—or different countries.

At that point, the legal question is no longer just what is best for the child, but which court has authority, which laws apply, and whether a court can stop a parent from relocating or taking a child across borders.

These cases require more than routine family law experience. They require a deep understanding of jurisdiction, emergency authority, and interstate and international custody enforcement laws, including the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA).

Why Jurisdiction Matters in Custody Cases

In custody law, jurisdiction is everything. If a court does not have jurisdiction, it cannot issue custody orders, enforce parenting plans, or stop an improper relocation. Filing in the wrong court—or waiting too long—can permanently alter a parent’s rights.

What Is the UCCJEA?

The UCCJEA governs which state has authority to make custody decisions when parents live in different states. Arizona has adopted the UCCJEA, as have nearly all U.S. states. The law prevents forum shopping, discourages abduction, and promotes cooperation between courts.

Key UCCJEA Concepts Parents Often Don’t Realize

Home State Matters—But Timing Is Critical

The child’s home state is generally where the child lived for six months before a custody case is filed. Delays can shift jurisdiction.

Emergency Jurisdiction Is Limited

Emergency jurisdiction allows courts to act quickly when a child is in danger, but such orders are usually temporary.

Once Jurisdiction Is Established, It Is Hard to Change

A court that properly establishes jurisdiction often retains it even if a parent later moves.

Custody Disputes Across State Lines

These cases often involve emergency motions, court-to-court communication, and rapid deadlines. Mistakes can be difficult to fix.

Custody Disputes Across International Borders

International disputes may involve foreign courts, treaties, and enforcement challenges. Speed and experience are critical.

Why Experience Matters

These cases require strategic decision-making and immediate action. Errors can permanently affect custody rights.

Frequently Asked Questions

What is the UCCJEA and why does it matter in custody cases?

The Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA) determines which state has legal authority to make custody decisions when parents live in different states. It prevents conflicting court orders and discourages child abduction or forum shopping.

Which state has jurisdiction over a custody case?

In most cases, the child’s home state has jurisdiction. The home state is generally where the child lived for the six months immediately before a custody case is filed. Timing is critical, and delays can change jurisdiction.

What happens if parents file custody cases in two different states?

The UCCJEA requires courts to communicate with each other to determine which court has proper jurisdiction. One court will ultimately dismiss or stay its case once jurisdiction is resolved.

Can an Arizona court stop a parent from moving a child to another state?

Yes, in certain circumstances. If Arizona has jurisdiction and a relocation would harm the child or violate existing orders, the court may restrict relocation or order the child’s return.

What is emergency jurisdiction under the UCCJEA?

Emergency jurisdiction allows a court to act quickly when a child is at immediate risk of abuse, abandonment, or danger. Emergency orders are usually temporary and must be followed by proper jurisdictional proceedings.

What if my child was taken to another state without my permission?

You may need to act quickly. Depending on timing and circumstances, Arizona courts may retain jurisdiction and order the child’s return. Delays can affect jurisdiction, so immediate legal advice is critical.

How are international custody disputes different from interstate cases?

International custody disputes may involve foreign courts, international treaties, and enforcement challenges. Jurisdiction, timing, and coordination between legal systems are far more complex than interstate cases.

Can Arizona courts enforce custody orders from another state or country?

Arizona courts can enforce valid custody orders from other U.S. states under the UCCJEA. Enforcement of international orders depends on treaties, foreign law, and specific circumstances.

What happens if a parent relocates before a custody order is in place?

Relocating before a court order is issued can significantly affect jurisdiction and custody rights. In some cases, the new location may become the child’s home state if no action is taken in time.

How long does a court keep jurisdiction once it is established?

Once a court properly establishes jurisdiction, it often retains authority until certain legal requirements are met. Moving alone does not automatically change jurisdiction.

Do I need an attorney experienced with UCCJEA issues?

Yes. UCCJEA cases involve strict rules, deadlines, and court-to-court procedures. Mistakes can permanently affect custody rights, making experienced legal guidance essential.

What is the biggest mistake parents make in cross-border custody disputes?

Waiting too long to act or filing in the wrong court. Jurisdictional errors can be extremely difficult—or impossible—to fix after deadlines pass.

Can mediation work in interstate or international custody cases?

In some cases, yes—particularly when jurisdiction is clear and both parents are cooperative. However, mediation is not appropriate in all cross-border custody disputes, especially when safety or enforcement is an issue.

When should I seek legal help in a cross-border custody situation?

Immediately. If a custody issue involves another state or country, early legal advice can determine which court has authority.
