Under the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA), the state that decides a child’s custody case is almost always the child’s “home state” — the state where the child has lived with a parent for the six consecutive months before the case was filed. Every state has adopted this law, and it funnels competing custody disputes into a single court so that parents in different states can’t get conflicting orders. Filing in the wrong state gets the case dismissed, which is why UCCJEA jurisdiction is the first question any lawyer asks when parents live apart.
The Home State Test
The six-month rule is the heart of the statute. If a child has lived in one state with a parent, or with someone functioning as a parent, for at least six consecutive months before the custody case is filed, that state has first claim on the case. For a baby under six months old, the home state is wherever the child has lived since birth.
Short absences don’t restart the clock. A two-week trip to see grandparents in another state, or a parent’s business travel, still counts toward the six-month window. The UCCJEA doesn’t put a hard limit on how long a “temporary” absence can last, so judges look at the circumstances and at whether the parent intended to return. Vacations and work trips almost always qualify. A months-long stay elsewhere gets more scrutiny.
The rule also protects the parent who stays behind. If one parent takes a child to another state, the original state remains the home state for six months, as long as the other parent still lives there. A parent who moves to a new state and files for custody three months later will almost certainly lose on jurisdiction. The new state simply doesn’t qualify yet.
The phrase “person acting as a parent” has a specific meaning. A non-parent qualifies only if they have had physical custody of the child for at least six consecutive months within the year before filing and either hold a court order granting legal custody or have a legal claim to it under state law. A grandparent raising a child full time under an informal arrangement likely qualifies. A weekday babysitter does not.
When No State Qualifies as the Home State
Sometimes no state meets the home state test — the family moved frequently, or the child spent less than six months in each place. The UCCJEA then provides backup tests that courts apply in strict order.
Significant Connection
The first fallback asks whether the child and at least one parent have a meaningful tie to the state — more than just physical presence — and whether the state holds substantial evidence about the child’s life, including school, medical, and family information. A court cannot use this test while a home state exists and is willing to hear the case.
Judges look for real roots: school enrollment, an established doctor or therapist, extended family who interact with the child regularly. A recently signed apartment lease won’t do it.
The Last-Resort Tests
If no state qualifies under either the home state or significant connection test, a court can take jurisdiction when all courts that could have qualified under those tests have declined. And if no court anywhere would have jurisdiction under any of the preceding tests, the filing state can hear the case as a last resort. These situations are rare, but they prevent a child from falling into a jurisdictional gap.
Emergency Jurisdiction
Child safety can’t wait for jurisdictional analysis. Under Section 204, any state where the child is physically present can step in on a temporary basis if the child has been abandoned or faces an immediate threat of mistreatment or abuse, including situations where a sibling or parent is being harmed. A parent fleeing domestic violence with children can seek emergency protection in the state where they land.
Emergency orders are meant to be temporary. They protect the child while the home state court takes up the case on the merits. If no prior custody order exists and the home state does not act within a reasonable period, an emergency order can eventually become permanent. Courts treat this power carefully. It exists for genuine emergencies, not as a workaround.
When a Court With Jurisdiction Steps Aside
Having jurisdiction doesn’t mean a court must use it. The UCCJEA gives judges two reasons to decline.
Inconvenient Forum
Under Section 207, a court can decline jurisdiction if another state is a more appropriate forum. The judge weighs eight factors: whether domestic violence has occurred and which state can better protect the parties and the child; how long the child has lived outside the state; the distance between the two competing courts; the parents’ financial circumstances; any agreement between the parents on where to litigate; where the relevant evidence and witnesses are, including the child; which court can handle the case more efficiently; and which court is already familiar with the facts.
Domestic violence sits at the top of the list by design. If an abuser is pushing to litigate in the original state to keep control, the court should weigh that heavily.
Unjustifiable Conduct
Section 208 handles a harder problem: a parent who manufactures jurisdiction by wrongful conduct, such as taking a child across state lines and hiding. When a court finds that the party seeking jurisdiction engaged in unjustifiable conduct to establish it, the court must decline the case.
The financial consequences are steep. The court must order the offending party to pay the other parent’s costs — attorney fees, travel, investigative fees, witness costs, and child care expenses tied to the proceeding. Fee-shifting is mandatory unless the offending party proves it would be clearly inappropriate.
One carve-out matters: a domestic violence victim who flees with the children to escape abuse should not be treated as having engaged in unjustifiable conduct, even if the departure was technically unauthorized. The provision targets abduction for tactical advantage, not escape from danger.
Modifying an Order From Another State
Once a state issues a custody order, that state keeps exclusive authority over changes. The UCCJEA calls this “exclusive continuing jurisdiction.” It lasts as long as the child or at least one parent remains in the state and keeps a significant connection to it. No other state can modify the order while those conditions hold, no matter where the child currently lives.
Exclusive continuing jurisdiction ends in one of two ways. The original court determines it no longer has a significant connection to the case, or the child, both parents, and anyone acting as a parent have all permanently left the state. If even one parent stays behind, the original state keeps control. A parent who moves cannot ask a local judge in the new state for a modified visitation schedule while the other parent still lives in the issuing state. The new state has to satisfy the standard jurisdictional tests first.
The Affidavit Required at Filing
Every parent filing a custody case must submit sworn information with the initial paperwork. Section 209 requires it in every case. The affidavit must disclose:
- The child’s current address
- Every place the child has lived during the past five years, and the names and addresses of the people the child lived with
- Any other custody, visitation, domestic violence, protective order, termination of parental rights, or adoption case involving the child, in any state
- Any person not named in the case who has physical custody of the child or claims custody or visitation rights
The duty to disclose doesn’t end with the first filing. Both parents must keep the court informed of any new proceeding involving the child in any state. Courts rely on this information to decide whether they have jurisdiction and whether another court is already handling the matter. Incomplete or false information costs credibility with the judge, and it can trigger the unjustifiable conduct provisions.
Enforcing an Existing Order After a Move
A custody order from one state doesn’t automatically carry weight in another. To enforce an order after moving, a parent registers it in the new state under Article 3 of the UCCJEA.
Registration requires filing a request with the new state’s court, two copies of the original order (one certified), and a sworn statement that the order has not been vacated or modified. The court notifies the other parent, who has 20 days to request a hearing to contest the registration. If no contest is filed, the order is confirmed and enforced like a local order, including through contempt and local law enforcement.
When a parent violates a custody order and time matters, the UCCJEA runs on an accelerated track. After an enforcement petition is served, the court must hold a hearing on the next judicial day, or on the first judicial day it can. That is one of the fastest timelines in family law.
In the most extreme cases, a court can issue a warrant directing law enforcement to take physical custody of a child. That requires a sworn petition showing imminent serious physical harm or imminent removal from the state, and the warrant must spell out the specific facts and provide for the child’s placement while the case is resolved.
International and Tribal Cases
The UCCJEA reaches beyond state borders in two ways. For international disputes, the law treats foreign countries like U.S. states for jurisdictional purposes. If a child lived with a parent in another country for six months, that country is the home state, and a U.S. court applies the same analysis. Separate treaties, including the Hague Convention on International Child Abduction, may also apply and provide additional remedies.
For cases involving Native American children, the Indian Child Welfare Act takes priority where it applies. Outside ICWA-governed proceedings, the UCCJEA treats tribal courts the same as state courts, and a tribal order made under substantially matching jurisdictional standards must be recognized and enforced under Article 3.
The Federal Backstop
The UCCJEA is state law, adopted state by state. A federal statute — the Parental Kidnapping Prevention Act — backs it up by requiring every state to enforce custody and visitation orders made by a court with proper jurisdiction, and by barring states from modifying another state’s order except in narrow circumstances.1Office of the Law Revision Counsel. 28 USC 1738A – Full Faith and Credit Given to Child Custody Determinations2Office of Justice Programs.
