UCCJEA Home State Rule: Six-Month Residency, Infants, and Absences

Under the Uniform Child Custody Jurisdiction and Enforcement Act, the home state rule says a child’s home state is the state where the child lived with a parent for at least six consecutive months immediately before a custody case is filed. That state has first priority to decide the initial custody dispute, and no other state can take the case while a home state exists.¹

The Six-Month Residency Requirement

The rule is mechanical. A state qualifies as the child’s home state if the child lived there with a parent for at least six consecutive months right before the custody case begins.² Physical presence is what counts. Not a parent’s legal domicile. Not an intention to stay. The theory is that the state where the child has actually been living, going to school, and seeing a doctor is best equipped to evaluate the child’s circumstances.

The six months must be consecutive and must run up to the filing date. Filing even a few days short of the mark can leave a court without jurisdiction. If you moved to a new state with your child four months ago and the other parent files a custody action, the previous state almost certainly keeps home-state status.

The rule isn’t limited to biological parents. The UCCJEA also recognizes a “person acting as a parent,” defined as someone who has had physical custody of the child for at least six consecutive months within the past year and who has been awarded legal custody or claims a right to it.¹ A grandparent or stepparent who meets that standard can establish a home state the same way a biological parent can.

Infants Under Six Months

A newborn cannot meet a six-month residency standard, so the UCCJEA writes a separate rule for babies. For a child under six months old, the home state is wherever the child has lived from birth with a parent or person acting as a parent.²

The “from birth” language matters. The infant cannot have lived anywhere else. If a parent gives birth in State A but moves to State B when the child is two months old, State A’s claim weakens from that point. A court in State B would look at how long the child has lived there since. For parents who anticipate a custody dispute around the time of a child’s birth, where the baby lives in those first weeks carries real jurisdictional weight.

What Counts as a Temporary Absence

Families travel. Kids visit grandparents over summer break. A parent takes a child out of state for medical treatment. None of these interruptions break the six-month residency clock. Temporary absences count toward the required period, so the clock keeps running as long as the absence is genuinely short-term and the family intends to return.²

Intent is what matters. A two-week vacation or a month with a relative doesn’t signal relocation. But if a parent takes the child to another state with no clear plan to return, a court may treat that as a permanent move rather than a temporary absence. The distinction usually comes down to evidence. Did the parent keep the lease? Leave belongings behind? Maintain the child’s school enrollment? Courts look at whether daily life stayed anchored in the original state during the absence.

Extended Home State Jurisdiction

One provision catches many parents off guard. If a child lived in a state long enough to establish it as the home state and was then taken to a different state within six months before a custody case is filed, the original state still has jurisdiction as long as at least one parent continues to live there.²

This exists to protect a left-behind parent. If one parent relocates with the child, the parent who stayed can still file in the original state within that six-month window and have the case heard there. The child doesn’t need to be physically present. Without this rule, a parent could defeat jurisdiction simply by leaving with the child and running out the clock. The window starts running immediately, though, so the left-behind parent cannot wait indefinitely.

Where the Home State Rule Sits in the Priority Order

The UCCJEA creates a clear hierarchy for determining which court hears an initial custody case, and the home state rule sits at the top. If a home state exists, no other state can exercise jurisdiction, even if the child has deep connections somewhere else.² A judge in another state may know the family well, but that familiarity doesn’t override the statutory priority.

Subject matter jurisdiction cannot be waived or created by agreement. Even if both parents consent to a particular state hearing the case, the court still must satisfy the UCCJEA’s requirements. A court that takes a case without proper jurisdiction risks having its orders thrown out on appeal.

When No State Qualifies as a Home State

Sometimes no state meets the six-month threshold. A family may have moved repeatedly, or a child may have been living abroad. The UCCJEA provides fallback options in a specific order.²

The first alternative is “significant connection” jurisdiction. A state can take the case if no home state exists (or the home state has declined jurisdiction) and the child plus at least one parent have a meaningful connection to the state beyond just being physically present. The court must also find that substantial evidence about the child’s care and personal relationships is available there. This might apply when a child has family and school ties in a state but hasn’t quite hit the six-month mark.

If no state qualifies on either home state or significant connection grounds, the UCCJEA allows any state to take the case as a last resort. This vacuum jurisdiction rarely comes up, but it ensures a child always has access to a court somewhere.¹

The Emergency Exception

The UCCJEA carves out one major override. Any state where a child is physically present can exercise temporary emergency jurisdiction if the child has been abandoned or if the child, a sibling, or a parent faces abuse or threats of abuse.¹ A parent fleeing to another state with a child doesn’t have to wait six months to get protection.

The scope is deliberately broad. The emergency doesn’t have to involve the child directly; threats against a sibling or the custodial parent are enough. Emergency orders are temporary by design. If a custody case is already pending in another state, the emergency court must set a deadline for the person seeking relief to obtain an order from the court with proper jurisdiction. If no custody case exists anywhere and no prior order is in effect, the emergency order can become permanent once the child has lived in the new state long enough for it to become the home state, provided proper notice was given.¹

After an Initial Custody Order Exists

The home state rule governs initial custody determinations. Once a court makes an initial order under the UCCJEA, the jurisdictional rules shift. That court retains exclusive authority to modify its own order, and no other state can change it even if the child moves away and establishes a new home state elsewhere.¹ This is where many parents get tripped up. Moving to a new state with your child does not automatically give the new state the power to change your custody arrangement.

The original state keeps this exclusive power until one of two things happens. Either the court itself determines that the child and all parties no longer have a significant connection to the state, or every relevant person (the child, both parents, and anyone acting as a parent) has moved away. Only the original court can decide the first question; a court in another state cannot unilaterally declare that the original state has lost its connection.²

Manufacturing a Home State Backfires

The UCCJEA has teeth for parents who try to manipulate jurisdiction. If a court finds that jurisdiction was created by a party’s unjustifiable conduct, such as taking the child to a new state to manufacture a home state claim, the court must generally decline to exercise that jurisdiction.¹ The court can also order the wrongdoer to pay the other party’s attorney fees, travel expenses, investigative costs, witness fees, and childcare costs incurred during the proceeding.

Disclosure requirements reinforce the deterrent. Every party filing a custody action must disclose under oath the child’s current address and every place the child has lived for the past five years, along with any other custody-related proceedings the party knows about.² Lying or withholding information can result in sanctions. The whole home state framework depends on accurate residency data, and courts treat the sworn disclosures accordingly.
