Jurisdiction Selector Calculator
Determine which state has jurisdiction over your divorce, custody, and property matters. This calculator analyzes UCCJEA home state rules, residency requirements, and identifies potential jurisdictional conflicts.
Understanding Jurisdiction in Family Law
Jurisdiction in family law is more complex than most people realize because divorce, custody, and property each follow different jurisdictional rules. A state may have jurisdiction to grant your divorce but lack authority to decide custody, or vice versa. When spouses live in different states -- increasingly common in our mobile society -- jurisdiction questions become critical strategic decisions that can affect which laws apply, how long the process takes, and what outcomes are likely.
Filing in the right state can save thousands of dollars and months of delay. Filing in the wrong state can result in your case being dismissed, or worse, having custody decided by a court far from where your children live. This calculator evaluates all the relevant factors and scores each potential state to help you and your attorney make an informed decision.
Divorce Jurisdiction: Residency Requirements
To file for divorce in a state, you (or in some states, your spouse) must meet that state's residency requirement. These range from no minimum in states like Alaska, South Dakota, and Washington to a full 12 months in states like New York, New Jersey, and Connecticut. Some states also require residency in a specific county for a certain period. If you recently moved, you may need to wait before you can file in your new state -- or you might still qualify in your former state if your spouse remains there.
Custody Jurisdiction: The UCCJEA
The Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA), adopted by all 50 states, establishes that custody jurisdiction belongs to the child's "home state" -- defined as the state where the child has lived with a parent for at least 6 consecutive months immediately before the custody proceeding. This rule prevents forum shopping and ensures stability for children. If a parent moves with the child to a new state, the old state retains jurisdiction for 6 months, giving the remaining parent time to file.
The home state rule has limited exceptions: if no state qualifies as the home state, the state with the most "significant connections" to the child (school, doctor, community ties) may take jurisdiction. Emergency jurisdiction exists when a child faces abuse or abandonment, but it is temporary and does not override home state jurisdiction for permanent orders.
Property Jurisdiction and Split Proceedings
Real property (land and buildings) is subject to the jurisdiction of the state where it is located, regardless of where the divorce is filed. If you own property in a state other than where you file for divorce, you may need a separate proceeding in that state to divide it. This is particularly relevant for community property vs equitable distribution states, as the laws governing division differ significantly and can change the outcome by tens or hundreds of thousands of dollars.
What happens if both spouses file in different states?
When competing petitions are filed in different states, courts apply the "first to file" rule in most cases. The court where the first petition was properly filed and served generally retains jurisdiction. However, if custody is involved, UCCJEA rules may override the first-to-file principle -- the child's home state has priority regardless of which parent filed first. This is why timing and strategy in filing are critical when spouses live in different states.
How does military service affect jurisdiction?
Military service creates unique jurisdictional options. Service members can typically file in: (1) the state where they are stationed, (2) the state of their legal domicile (which may differ from where they are stationed), or (3) the state where their spouse resides. The Servicemembers Civil Relief Act (SCRA) also provides protections against default judgments and can delay proceedings when deployment prevents participation. Military families should consult a JAG attorney in addition to civilian family law counsel.
Can jurisdiction change during a divorce case?
Once a court properly establishes jurisdiction, it generally retains it for the duration of the case -- this is called "continuing jurisdiction." However, if both parents and the child leave the state, jurisdiction can shift. For custody modifications after the divorce, the original state retains exclusive continuing jurisdiction as long as one parent remains there. If both parents have moved, the child's new home state can take jurisdiction for modifications.
