How a Child's Home State Is Identified

Custody disputes that cross a state line used to be decided twice. Two courts, each applying a standard about which forum was best placed, each reaching a defensible answer, each issuing an order. The uniform framework that replaced that approach works by removing the discretion at the jurisdictional stage entirely, and it does so with a definition that can be applied with a calendar.

The definition

Six consecutive months. The home state is the state in which the child lived with a parent, or a person acting as a parent, for at least six consecutive months immediately before the commencement of the proceeding.

Measured backwards from filing. The date that matters is the day the case began, and the six months is counted back from it. A move that occurs after filing does not change the answer, which is deliberate: it prevents jurisdiction being defeated by relocating once a case has started.

Living with a parent. The child must have been living with a parent or someone acting as a parent. A child staying temporarily with a relative while the parents remained elsewhere presents a question about who the child was living with, and the answer is factual.

Infants have their own rule. For a child less than six months old, the home state is the state in which the child has lived since birth, with the same allowance for temporary absences. This exists because the general definition is impossible to satisfy for a newborn.

Consecutive, with absences counted in. A period of temporary absence from the state is counted as part of the six months rather than breaking it. That single provision resolves most of the disputes the definition would otherwise generate.

How the count actually works

Ordinary travel does not interrupt. Holidays, visits to family, a hospital stay in a neighboring state, a summer with grandparents. These are the paradigm temporary absences and courts treat them as part of the period.

Court-ordered visitation does not interrupt. A child spending scheduled time with the other parent in another state remains living in the home state during that time, which is the arrangement the order itself contemplated.

A genuine relocation does interrupt. Where the household moved, possessions went, a lease was taken and a school was changed, the child began living somewhere else and a new period started.

Ambiguous cases turn on the surrounding facts. A stay that was intended to be temporary and became permanent, or a trial separation with a child in tow, is decided on what the arrangements showed rather than on what anyone later says was intended.

The burden sits with the party relying on the characterization. A parent asserting that a five-month absence was temporary has to establish it, and contemporaneous evidence — a lease with a return date, an enrollment held open, possessions left behind — is what does the work.

When no state qualifies

The gap is real and common. A family that moved three months ago has no home state: the new state is short of six months, and the old state's period did not run immediately before the filing.

The significant connection fallback. Where no state is the home state, or where the home state declines, a court may take jurisdiction if the child and at least one parent have a significant connection with the state beyond mere physical presence, and substantial evidence about the child's care, protection, training and personal relationships is available there.

Evidence is the operative word. The fallback is designed around where the information is: school records, medical providers, therapists, teachers, neighbors. It frequently points at the state just left, because that is where the child's history sits.

A further fallback exists. Where no state has jurisdiction under either test, or all decline, a state with an appropriate connection may act, which prevents a case being left with nowhere to go.

Emergencies are separate. A court may act on a temporary basis where a child present in the state is at risk, which is a different power on a different footing and is examined in when a court may act for a child in danger.

Why the definition is worth knowing early

It decides where the case will be fought. Everything else — which lawyer, which rules, how far anyone has to travel, which state's substantive law applies to the merits — follows from this determination.

It is affected by the timing of a move. A parent contemplating relocation should know that the six-month clock in the new state begins on arrival, and that filing before it matures produces a different analysis. This is not an argument for manipulating the timetable; it is an argument for knowing what the timetable is.

It is affected by the timing of a filing. Because the count runs from commencement, the date a case starts can determine which state qualifies. Where both parents are considering filing, the position can change week by week.

It cannot be fixed by agreement alone. Parents cannot confer jurisdiction on a state that does not have it under the act, though a court that has jurisdiction may decline it in favor of a more appropriate forum. What can be agreed is examined in the controlling order when two states have issued one.

Getting it wrong costs the whole proceeding. An order made without jurisdiction under the act is vulnerable to being disregarded elsewhere, which means a parent can litigate for a year and hold something the other state will not enforce — the position described in expedited enforcement and what a second court may not reopen.

What the determination does not decide

Not the outcome. Identifying the home state settles which court hears the case and nothing about what that court will order. Parents sometimes treat the jurisdictional result as a victory or a defeat on the merits, and it is neither.

Not which state's substantive law applies to every question. The court applies its own law to the custody determination, but questions of paternity, of the validity of a prior agreement, or of property can be governed by another state's law under ordinary choice-of-law principles, as described in the test courts use for contracts.

Not support. Custody and support run on separate uniform frameworks with separate jurisdictional rules, and the same state does not always have both. A court with custody jurisdiction may lack the personal jurisdiction over a parent that a support order requires.

Not enforcement anywhere else. An order made by the home state is enforceable elsewhere, but only after the mechanics in registering a custody order in a second state have been used.

Not permanence. The home state analysis governs the initial determination. Whether the same court keeps the power to change the order later is a separate question with its own rules, examined in which state keeps the power to modify. Where a child has not lived anywhere long enough for the ordinary test to produce an answer, the fallback is set out in the six-month rule and what happens when it is not met.
