Interstate Custody Rules (UCCJEA): Which State Decides
Updated 2026-10-06
When parents and children all live in the same state, it is usually clear which court handles a custody case. When a parent moves, or the parents live in different states, the question gets harder. Which state's court can make a custody order? Which state can change it later? And how is an order from one state enforced in another?
Most states answer these questions using a model law called the Uniform Child Custody Jurisdiction and Enforcement Act, or UCCJEA. This guide explains its main ideas in plain terms. Each state adopts the law in its own version, so the details in your state may differ.
Why custody has special rules about states
Custody is mainly a matter of state law, heard in state courts. The U.S. Courts comparison of federal and state courts explains that both the federal government and each state have their own court systems, and that family law cases are generally handled by state courts.
Without shared rules, two states could each issue different custody orders for the same child. The Uniform Law Commission, a nonprofit that drafts model state laws, explains in its UCCJEA summary that competing decisions "simply confuse, rather than conclude the dispute." Before uniform rules existed, some parents moved children across state lines hoping a new court would change an order they did not like.
Where the UCCJEA came from
According to the Uniform Law Commission:
- An earlier model law, the Uniform Child Custody Jurisdiction Act (UCCJA), was created in 1968.
- Congress later passed the Parental Kidnapping Prevention Act (PKPA) for a similar purpose.
- The two laws differed in some ways, which caused confusion.
- In 1997, the Commission created the UCCJEA to bring the earlier act in line with the PKPA and to add rules for enforcing custody orders across state lines. The UCCJEA replaces the UCCJA.
Each state decides whether and how to adopt a uniform act, so always check your own state's version.
Home state priority
The central idea in the UCCJEA is the child's home state. The Uniform Law Commission explains that under the UCCJEA, any state that is not the child's home state will defer to the home state, if there is one, when deciding who can hear a custody case.
"Home state" is defined in each state's version of the law. In general, it is tied to where the child has lived with a parent for a period of time before the case starts. Because the exact definition and timing matter a lot, check your state's statute or ask a lawyer before you file. A recent move can change the answer.
If there is no home state, the law looks at other connections, such as which state has a significant connection with the child and family.
Continuing exclusive jurisdiction
Once a state properly makes a custody order, the UCCJEA generally keeps the case there. The Uniform Law Commission describes this as continuing exclusive jurisdiction. The first state keeps control as long as, by its own determination, it keeps a significant connection with the people involved, or until everyone has moved away.
In practical terms, if a custody order was made in one state and one parent still lives there, the other parent usually cannot simply move with the child and ask a new state's court to change the order. Changes generally go back to the original court, unless that court gives up jurisdiction or everyone has moved.
Temporary emergency jurisdiction
There is an exception for emergencies. The Commission explains that a state where the child is present may take temporary emergency jurisdiction when there is abandonment, mistreatment, or abuse of the child, or threats to a sibling or parent. This power is meant to protect the person in danger. It is generally temporary, while the case is sorted out with the state that has the right to decide custody.
If you are in danger, contact local law enforcement and seek help right away.
Enforcing an order from another state
The UCCJEA also helps parents enforce custody and visitation orders across state lines. According to the Uniform Law Commission:
- A state must enforce a custody or visitation order from another state that substantially conforms with the act.
- One method is to register the out-of-state order. If the registration is not contested, the order can be enforced like a local one.
- There is also a faster process, with an expedited hearing.
- If a child is in danger or may be removed from the state, a court may issue a warrant to take physical custody of the child.
- The act gives prosecutors and law enforcement a role in locating children and enforcing orders.
Practical steps if you are dealing with two states
- Write down a timeline of where the child has lived, with dates and addresses.
- Gather any existing orders, including temporary orders and protective orders.
- Do not move a child across state lines in the middle of a dispute without legal advice. It can affect which court decides and how a judge views the situation.
- Ask about filing in the right place. Maryland's courts, for example, note on their child custody page that when a child lives out of state, there are special rules about where to file, and suggest contacting a lawyer.
A family law lawyer who handles interstate cases can help figure out which court has the power to decide. For free or low-cost help, see the USAGov legal aid page.
Frequently asked questions
Can I file for custody in my new state right after moving?
Often not right away. The UCCJEA gives priority to the child's home state, and the definition depends on where the child has lived and for how long. Check your state's rules before filing.
Does the UCCJEA cover child support?
No. Child support between states is handled by a different uniform law. The UCCJEA deals with custody and visitation.
What if the other parent took the child to another state?
Contact a lawyer and, if there is danger, law enforcement. The UCCJEA has tools for enforcing existing orders across state lines.
Does every state follow the UCCJEA exactly?
Each state adopts its own version. The main ideas are similar, but details can differ, so check the law in the states involved.
