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).
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.
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.
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 allows courts to act quickly when a child is in danger, but such orders are usually temporary.
A court that properly establishes jurisdiction often retains it even if a parent later moves.
These cases often involve emergency motions, court-to-court communication, and rapid deadlines. Mistakes can be difficult to fix.
International disputes may involve foreign courts, treaties, and enforcement challenges. Speed and experience are critical.
These cases require strategic decision-making and immediate action. Errors can permanently affect custody rights.
At Best Law Firm, we handle UCCJEA jurisdiction disputes, emergency filings, interstate enforcement, and high-conflict custody cases. Time, strategy, and experience matter.
Do not assume jurisdiction, delay action, rely on informal agreements, or move a child without legal advice.

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.
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.
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.
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.
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.
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.
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.
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.
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.
Once a court properly establishes jurisdiction, it often retains authority until certain legal requirements are met. Moving alone does not automatically change jurisdiction.
Yes. UCCJEA cases involve strict rules, deadlines, and court-to-court procedures. Mistakes can permanently affect custody rights, making experienced legal guidance essential.
Waiting too long to act or filing in the wrong court. Jurisdictional errors can be extremely difficult—or impossible—to fix after deadlines pass.
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.
Immediately. If a custody issue involves another state or country, early legal advice can determine which court has authority.
