Military Custody Jurisdiction in California: How Courts Decide Where a Case Belongs

Whether a California court can decide a military family's custody case usually turns on whether California is the child's home state, meaning the child lived here with a parent for six consecutive months before the case was filed. A parent's duty station does not decide it; where the child lived does.

Most people facing this question are in the middle of something unsettled. It might be a Sailor stationed in San Diego whose child is living with the other parent in Texas. It might be a military spouse who just arrived on PCS orders carrying a custody order from another state. Or it might be a parent bracing for a deployment and wondering what happens to the schedule the family worked out. Before anyone can talk about who the child lives with, there is a quieter question underneath: which court is even allowed to decide.

This article explains how California answers that question for military families, from the six-month home-state rule through deployment, PCS moves, the Servicemembers Civil Relief Act and the custody process in San Diego County.

What 'Jurisdiction' Means in a Military Custody Case

Jurisdiction is a court's legal authority to hear and decide a case. A custody order made by a court that lacks that authority is open to challenge as void, and another state does not have to respect it. That is why jurisdiction comes first, before any discussion of schedules, schools or which parent the child lives with.

In California, custody jurisdiction is governed by the Uniform Child Custody Jurisdiction and Enforcement Act, or UCCJEA, which California has enacted as Family Code sections 3400 through 3465. Nearly every state has adopted the same uniform act. Its central purpose is to prevent two states from issuing competing custody orders for the same child.

That problem comes up often in military families because of PCS moves. A permanent change of station, or PCS, is a military-ordered relocation to a new duty assignment. A family can live in three states in five years, and each move raises the question of which state's courts now have authority over the children.

Jurisdiction is a separate question from custody itself, and it is also distinct from where a divorce case itself may be filed, which the site's guide to divorce jurisdiction covers. A California court first asks whether it has authority over the custody question. Only then does it reach the merits, meaning who gets custody and on what schedule. Under the UCCJEA, a California court uses the same framework to decide whether California is the right forum, whether another state's existing order controls, and whether it should defer to a case already moving forward in another state.

The UCCJEA's Home-State Rule and How It Applies to Military Families

Family Code section 3421(a)(1) is the starting point. Generally, a California court has jurisdiction to make an initial custody determination if California "is the home state of the child on the date of the commencement of the proceeding," or was the home state within six months before the case began and a parent still lives in California while the child is away.

"Home state" has a precise meaning. Family Code section 3402(g) defines it this way:

"'Home state' means the state in which a child lived with a parent or a person acting as a parent for at least six consecutive months immediately before the commencement of a child custody proceeding. In the case of a child less than six months of age, the term means the state in which the child lived from birth with any of the persons mentioned. A period of temporary absence of any of the mentioned persons is part of the period."

In plain terms, the child must have lived in California with a parent for six months in a row right before the case is filed. For a baby under six months old, the home state is wherever the baby has lived since birth.

Military life puts pressure on that clock. A PCS order can move a child out of California before the six months are complete, or bring a child here only weeks before a separation. Either way, California may not yet be, or may no longer be, the home state.

The last sentence of section 3402(g) matters a great deal to service families. A temporary absence counts toward the six months. TDY, or temporary duty, is a short-term military assignment away from the home station. A parent's TDY or deployment does not necessarily break a child's California residence if the child stays here.

When no state qualifies as the home state, California law generally allows a court to take jurisdiction based on a significant connection: the child and at least one parent have a significant connection with California, and substantial evidence about the child's care is available here. Separately, section 3424 gives a California court temporary emergency jurisdiction when the child is present here and has been abandoned, or needs protection in an emergency for reasons including mistreatment or abuse of the child or a family member, subject to the duration limits the section sets.

When two states are both involved, Family Code section 3410 allows a California court to communicate with the court in the other state. If the parties cannot take part in that communication, they must be given a chance to present facts and legal arguments before a decision on jurisdiction is made.

When a Servicemember Is Stationed in California but the Child Lives Elsewhere

A duty station in California does not, by itself, give California courts jurisdiction over a child who lives in another state. Jurisdiction follows the child's home state, not the parent's assignment.

If the child has lived in another state with a parent for six consecutive months before the case is filed, that state is the home state. Under section 3421, California's authority to make an initial custody order is limited to the circumstances that section lists, so a California court generally does not make that initial order when another state is the child's home state. A servicemember stationed in California in that position may find the case belongs in the child's home state, or that California can act only once the child has lived here long enough to make California the home state.

Domicile and physical presence are different ideas. Domicile is the place a person treats as their permanent legal home. A service member may keep a legal residence in one state while stationed in California for years. The home-state test, though, looks at where the child physically lived, not at anyone's legal residence or a parent's orders.

Even when California has jurisdiction, Family Code section 3427 allows a California court to decline it if it finds California is an inconvenient forum and another state's court is more appropriate. A party may raise that issue, or the court may raise it on its own.

For a parent at a San Diego command with a child several states away, this can feel backward. The law's focus is the child's settled life, which is why the analysis keeps returning to where the child has been living.

How Deployment Affects an Existing California Custody Order

Family Code section 3047 is the California rule written for military orders. Section 3047(b)(1) provides that when a parent with sole or joint physical custody or visitation receives temporary duty, deployment or mobilization orders that require a move a substantial distance from home, or that otherwise materially affect that parent's ability to exercise custody or visitation, any necessary change to the custody order "shall be deemed a temporary custody order made without prejudice." That order is then subject to review and reconsideration when the parent returns.

Federal law points the same way. Under the Servicemembers Civil Relief Act, 50 U.S.C. § 3938(a) requires a temporary custody order based solely on a deployment to expire no later than the period the deployment justifies. Under 50 U.S.C. § 3938(b), when someone seeks a permanent custody change, no court may consider a servicemember's deployment, or the possibility of deployment, as the sole factor in deciding the child's best interest. Where state law gives a deploying parent greater protection for a temporary order, the court applies the higher state standard.

During a deployment, the court may, on the relocating parent's motion, grant reasonable visitation to a stepparent, grandparent or other family member. Under Family Code section 3047(b)(3)(B), that happens only if the court makes the findings the section lists. It is not automatic, and it is not the parent's own choice to make.

A custody order can also address moves. Under Family Code section 3024, if the court does not consider it inappropriate, a custody order may specify that a parent must notify the other parent before changing the child's residence for more than 30 days, unless there is prior written agreement to the removal. To the extent feasible, that notice is given at least 45 days before the move, to allow time to mediate a new custody agreement. In San Diego County, that mediation is child custody recommending counseling with the court's Family Court Services under Family Code sections 3170 and 3183.

These deployment rules run on a different track from an ordinary custody modification. The family's longer-term arrangement is meant to be revisited on the parent's return rather than rewritten because of the absence. The site's guide to deployment and child custody walks through section 3047 in more detail, and the separate question of military family care plans is covered on its own page.

Modifying a Custody Order When a Military Family Moves to California

A court that properly makes a custody order generally keeps exclusive, continuing jurisdiction over it. Under Family Code section 3422, that authority lasts until a court of that state decides that neither the child, nor the child and one parent, nor the child and a person acting as a parent have a significant connection with the state, and that substantial evidence about the child's care is no longer available there. It also ends when a court finds that the child, the child's parents, and any person acting as a parent no longer live in that state.

Family Code section 3423 sets the limit for California. Generally, a California court may not modify another state's custody order unless California would have jurisdiction to make an initial order, and either the other state's court determines it no longer has exclusive, continuing jurisdiction or that California would be a more convenient forum, or a court finds that the child and the parents no longer live in the other state.

The practical result is that a PCS move to California does not automatically transfer a custody case here. If one parent still lives in the state that issued the order, that state's court often keeps authority over changes, even after the child has settled in San Diego. When the child and both parents have left the original state and California has become the home state, California may gain the authority to modify. More on how relocation orders interact with custody is in the guide to PCS and child custody.

Meanwhile, an out-of-state order can still be put to work here. Under Family Code section 3445, a custody order from another state may be registered in California, with or without a request to enforce it, by sending the appropriate California court the documents the section requires, beginning with a letter or other document requesting registration. Registration lets a California court enforce the order. It does not, by itself, give California the power to change it.

The Servicemembers Civil Relief Act and Custody Proceedings

The Servicemembers Civil Relief Act, or SCRA, protects service members' legal rights in civil cases, and its stay and default sections expressly include child custody proceedings. Military OneSource explains that the SCRA applies to active-duty members, certain National Guard and reserve members on federal orders, and their dependents. Active duty here means full-time military service, as distinguished from reserve or Guard service when not on federal orders.

The stay rule is in 50 U.S.C. § 3932. It applies when a servicemember is in military service, or within 90 days after leaving it, and has received notice of the case. At any stage before final judgment, the court "may on its own motion and shall, upon application by the servicemember, stay the action for a period of not less than 90 days," if the application includes two things: a letter or other communication explaining how current military duty materially affects the servicemember's ability to appear and giving a date when the servicemember will be available, and a letter or other communication from the commanding officer stating that current duty prevents appearance and that military leave is not authorized. Asking for a stay is not an appearance for jurisdictional purposes and does not waive defenses. A servicemember may ask for an additional stay, and if the court refuses one, it must appoint counsel.

Default protection is in 50 U.S.C. § 3931. When a defendant has not appeared, the court must require the other side to file an affidavit stating whether the defendant is in military service. If it appears the defendant is in military service, the court may not enter judgment until it appoints an attorney to represent the defendant. A default judgment entered during service, or within 60 days after it, may be reopened on application filed no later than 90 days after service ends, if the servicemember was materially affected by service in making a defense and has a meritorious or legal defense.

The SCRA does not stop a custody case from being filed, and it does not end one. A stay is temporary, and the case resumes when it ends unless the court extends it. Military OneSource describes it as a way for a deployed parent to postpone hearings when the other parent seeks to change custody during an absence.

Best-Interest Factors California Courts Apply in Military Custody Cases

Once jurisdiction is settled, California decides custody by the child's best interest. Family Code section 3020 makes the child's health, safety and welfare the court's primary concern. Family Code section 3011 lists factors the court must consider, among any others it finds relevant and consistent with section 3020, including the health, safety and welfare of the child; any history of abuse by one parent or any other person seeking custody against the child or the other parent; the nature and amount of contact with both parents; and the habitual or continual illegal use of controlled substances, the habitual or continual abuse of alcohol, or the habitual or continual abuse of prescribed controlled substances by either parent.

When awarding custody to either parent, Family Code section 3040(a)(1) asks the court to consider, among other factors, which parent is more likely to allow the child frequent and continuing contact with the noncustodial parent, consistent with sections 3011 and 3020. Under Family Code section 3100(a), the court grants a parent reasonable visitation when it is shown that the visitation would be in the child's best interest.

Military life enters this analysis as facts, not as a separate test. A court may weigh the stability of a current assignment against the disruption of a coming PCS, how a deployment schedule affects day-to-day care, and the child's school, community and sibling ties. The Judicial Council's California Courts self-help guide notes that parenting plans must be in the children's best interests, and that a court may allow virtual visits when one parent lives far away. The site's overview of military child custody covers these factors further.

Domestic violence changes the starting point. Under Family Code section 3044(a), on a finding that a parent perpetrated domestic violence within the previous five years against the other parent, the child or the child's siblings, or another listed person, there is a rebuttable presumption that awarding that parent sole or joint physical or legal custody is detrimental to the child's best interest. Under section 3044(b)(1), neither the preference for frequent and continuing contact with both parents nor the preference for contact with the noncustodial parent may be used to rebut that presumption, in whole or in part.

Emergency orders have their own threshold. Under Family Code section 3064(a), the court will not grant or modify custody on an ex parte basis, meaning on short notice to the other side, unless there is a showing of immediate harm to the child or immediate risk that the child will be removed from California. Under section 3064(b), immediate harm includes, among other things, a parent's recent or continuing acts of domestic violence and recent or continuing sexual abuse of the child, and the court must consider a parent's illegal access to firearms and ammunition.

Where Military Custody Cases Are Filed in San Diego County

When California has jurisdiction and the family lives in San Diego County, the custody case is heard by the Superior Court of California, County of San Diego. That includes custody issues within a divorce and stand-alone custody cases for active-duty parents, military spouses and recently separated veterans. The region's many installations mean the court regularly sees families shaped by PCS orders and deployments.

When custody or visitation is contested, the court must set the contested issues for mediation under Family Code section 3170. In San Diego County, that mediation is child custody recommending counseling with the court's Family Court Services. Domestic violence cases are handled by Family Court Services under a separate written protocol approved by the Judicial Council, under section 3170(b).

Under Family Code section 3183(a), except as provided in section 3188, the mediator may, consistent with local court rules, submit a recommendation to the court on custody or visitation if the mediator has first provided the recommendations in writing to the parties and their attorneys, including counsel for any minor children, before the hearing. Family Court Services calls this person the Family Court Counselor. Family Court Services states that if no agreement is reached, the counselor makes a recommendation and the court hearing proceeds. The judge makes the decision.

Military OneSource, a Department of Defense program, publishes general custody information for military families, including the SCRA and family care plans.

If You'd Like to Talk Through Your Situation

Jurisdiction questions in military custody cases often hinge on dates and addresses that are easy to overlook: when the child arrived in California, who still lives in the state that issued an earlier order, and how orders and deployments line up with those timelines. A consultation is a place to raise those questions about which court may have authority and how California's deployment and SCRA rules work. Military Family Law Advocates practises California family law only, so where another state's court holds jurisdiction, a lawyer licensed there may be the better fit for that part of the case.
