Does serving in the military cost a parent custody?

No, not by itself. A parent in uniform is judged by the same test as any other parent, the child’s best interest, and both federal and state law now say in terms that deployment is not a reason on its own to take custody away. Section 3938 of the Servicemembers Civil Relief Act provides that when a motion or petition seeks a permanent order modifying custody of a service member’s child, “no court may consider the absence of the servicemember by reason of deployment, or the possibility of deployment, as the sole factor in determining the best interest of the child.” Most states have a statute that says something similar, and ten have adopted a uniform act written for exactly this situation.

What the law does not do is pretend a deployment has no effect. A parent who will be overseas for nine months cannot do the school run, and a court arranging a child’s life for those nine months has to arrange it around that fact. The protection is that the arrangement is temporary, that the absence is not held against the parent when they return, and that the parent gets a fair chance to be heard before it is made. The rest of this page is about how those three things work and what each parent should be writing down while they do.

This page is written for two readers. One is the service member who has orders, or expects them, and wants to know what happens to their time with their child. The other is the parent who will have the child while the other parent is away. Both have the same reason to keep a record, and it is the same kind of record: a dated account of their own days with the child. Nothing here is about watching the other parent. The examples use federal law, California and Texas, because their statutes say specific things that can be checked. Your own state’s law controls.

What does the Servicemembers Civil Relief Act do in a custody case?

The Servicemembers Civil Relief Act, in Title 50 of the United States Code, does two separate things for a parent in a custody case. One is about timing. The other is about what a court may decide.

A pause of at least 90 days. Section 3932 applies to “any civil action or proceeding, including any child custody proceeding” in which a party is in military service or was within the previous 90 days. At any stage before final judgment, the court “shall, upon application by the servicemember, stay the action for a period of not less than 90 days” if the application meets two conditions. It must include a letter or similar statement from the service member setting out how current duty materially affects their ability to appear and giving a date when they will be available, and a letter or similar statement from the commanding officer stating that current duty prevents appearance and that leave is not authorised at the time of the letter. Applying for the stay is not treated as an appearance for jurisdiction and does not waive any defence. A further stay can be applied for, and if the court refuses one, it must appoint counsel to represent the service member.

The words “child custody proceeding” were added to that section in 2008. Before that, service members relied on the general wording. Now the statute names the case type, and a court hearing a custody matter cannot say the stay does not reach it.

Temporary means temporary, and deployment is not the sole factor. Section 3938 was added for custody in particular. Subsection (a) says that if a court “renders a temporary order for custodial responsibility for a child based solely on a deployment or anticipated deployment of a parent who is a servicemember, the court shall require that the temporary order shall expire not later than the period justified by the deployment of the servicemember.” Subsection (b) is the sole-factor rule quoted above, which applies when someone asks for a permanent change. The section creates no federal right to sue, and it leaves in place any state law that gives the service member more protection, not less.

Deployment, the federal definition glossary

For the purposes of section 3938, deployment means “the movement or mobilization of a servicemember to a location for a period of longer than 60 days and not longer than 540 days pursuant to temporary or permanent official orders” that are designated as unaccompanied, that do not authorise dependent travel, or that otherwise do not permit the movement of family members to that location. A two-week exercise is not a deployment under this section. A three-year accompanied tour is not either. State statutes have their own definitions, and several are wider.

Two practical points follow. The stay is not automatic; it has to be applied for, with both letters, and the date of availability in the first letter is a date the court will hold the service member to. And the sole-factor rule does not stop a court from considering deployment at all. It stops a court from deciding a permanent change on deployment alone. A parent who wants a permanent change will be pointing to other facts, and the parent resisting it will want a record of their own that answers them.

What happens to a custody order during a deployment?

The order does not disappear, and it does not change by itself. What happens is that one parent asks the court for a temporary arrangement to cover the absence, or the parents agree one and have it entered. State statutes govern the details, and the two examples below show how different the details can be.

California: a temporary order without prejudice. Section 3047 of the Family Code says that a party’s absence, relocation or failure to comply with a custody order “shall not, by itself, be sufficient to justify a modification” if the reason is activation to military duty or temporary duty, mobilization in support of combat or other military operation, or military deployment out of state. Where orders require the parent to move a substantial distance or otherwise materially affect their ability to exercise custody, any necessary modification “shall be deemed a temporary custody order made without prejudice,” reviewed when the parent returns. On that review there is a presumption that the order reverts to what it was before, unless the court finds that is not in the child’s best interest, and the court may not order a custody evaluation as part of the review unless the other party makes a prima facie showing that one is needed. The temporary order must consider how the deploying parent can “maintain frequent and continuing contact with the child by means that are reasonably available,” and the deploying parent can ask the court to give visitation to a stepparent, grandparent or other family member to keep that contact going. If the deployment will affect the parent’s ability to appear, the court must, on motion, either hold an expedited hearing before departure or let the parent take part by phone, video or the internet.

From a family law practice
“Again, while it is generally best for the parents to agree on a temporary modification in such situations, it is important to remember that any agreed-upon modifications should be drafted by a licensed attorney into a stipulation and filed with the court so that it becomes a court order. It is also crucial that any stipulation specifically states that these modifications are temporary, and the prior order will become effective once the military parent returns.”
Christina Alkire, attorney, Cage & Miles, San Diego, California Published on the firm’s blog: Child Custody and Support During Military Parent’s Temporary Absence

Texas: a temporary order that ends on return. Section 153.702 of the Texas Family Code lets either conservator file for a temporary order when one of them is ordered to military deployment, mobilization or temporary duty that involves moving a substantial distance and materially affects their ability to exercise their rights, “without the necessity of showing a material and substantial change of circumstances other than the military deployment.” The temporary order can give the deploying parent’s rights to a designated person, and it can order the other parent to hand the child over to that person for the periods the deploying parent would have had. When the deployment ends and the conservator returns home, “the temporary orders under this section terminate and the rights of all affected parties are governed by the terms of any court order applicable when the conservator is not ordered to military deployment.”

Other states. The Uniform Deployed Parents Custody and Visitation Act was drafted by the Uniform Law Commission for this situation. The National Conference of State Legislatures reports that ten states have enacted it, that several others have passed similar legislation, and that the majority of states have some statutory provision addressing the custody and visitation rights of military parents. If your state is not California or Texas, the section that governs you will be in your state’s family or domestic relations code, and the details of notice, timing and reversion will be its own.

Federal (50 U.S.C. §§ 3932, 3938)California (Fam. Code § 3047)Texas (Fam. Code § 153.702)
Deployment alone as a reason to change custody Not the sole factor for a permanent change Not by itself sufficient to justify a modification Deployment is itself enough to ask for a temporary order
Temporary order Must expire no later than the period the deployment justifies Made without prejudice; presumed to revert on return Terminates when the conservator returns home
Contact during the absence Not addressed Court must consider orders for frequent and continuing contact by reasonably available means Court may award the parent’s periods to a designated person
Getting heard before departure Stay of at least 90 days on application with two letters Expedited hearing before departure, or electronic participation, on motion Temporary order process under the subchapter
After return Temporary order has expired Review, with a presumption the prior order returns Prior order governs again

Is a family care plan the same as a custody order?

No. A family care plan is a document the military requires so that the service member’s unit knows the children will be looked after and the member can deploy. A custody order is what a court has decided about the child. They cover the same weeks, and they need to name the same people, but one does not change the other.

Military OneSource, the Department of Defense’s own family support programme, states the requirement this way: “Generally, active-duty and Reserve Component service members with dependents who are either single or part of a dual-military couple must have a family care plan.” The plan names a caregiver, a backup, and the practical arrangements for money, transport and daily care while the member is away. Texas Access and Visitation, a state programme for parents with custody orders, puts the relationship to the court order in one sentence: “The care plan does not modify the current court order.”

From a family law practice
“A Family Care Plan is a command document. It satisfies a military readiness requirement. It does not grant your caregiver legal authority over your child, and it does not override a Texas custody order.”
Brandi Wolfe Law, PLLC, family law practice, San Antonio, Texas Published on the firm’s website: Military Family Care Plan Rules Every Texas Parent Should Know

The practical consequence is the one that catches parents out. A service member with primary custody names their own mother as caregiver in the plan. The court order gives the other parent rights. When the deployment starts, the caregiver in the plan has the service member’s paperwork and the other parent has a court order, and the court order wins. In Texas the designated-person process is the route for putting someone other than the other parent into the schedule, and it runs through the court. The plan should be written to match the order, and if the service member wants the order to say something different during the deployment, that is a motion to the court, filed early enough for the expedited hearing the statutes provide.

For the service member, the plan is also a record. It is dated, it is filed with the unit, and it says who was to care for the child and how. Keep a copy with your own record, alongside the date you gave it to the command and the date you told the other parent what was in it.

What should a service member write down before, during and after a deployment?

Every rule above turns on a date or a fact about your own days. The record that helps is a plain, dated account of them, written as they happen. It is about what you did, not about the other parent.

Before you leave.

While you are away.

When you return.

Entries written on the day, in a form that shows they have not been changed, are a different kind of evidence from an account reconstructed afterwards. A service member reconstructing nine months from memory is in the same position as any other witness. One who wrote each call down as it ended is not.

What should the parent at home write down?

The parent who has the child during a deployment has the same reason to keep a record, and the same rule applies: it is about your own care of the child, not about the other parent. A record kept to show that the deployed parent was absent proves nothing a court does not already know, and it reads badly. A record of how you kept the child’s life running is a different thing.

If you are the parent at home and the deployed parent is asking for a temporary change you think is wrong for the child, the same principle holds. Your case is your account of the child’s days, dated, written as they happened.

Where does the record sit?

Both parents’ records are answers to the same question a court will eventually ask: what happened, and when. The federal stay needs a date of availability. The California review starts from the date of return. The Texas temporary order ends on the date the conservator is home. The sole-factor rule invites the court to look at everything except the deployment, and everything except the deployment is the record of ordinary days that each parent kept.

Timing matters as much as content. An account written once a dispute exists is what every witness produces. Entries written on the day, in a form that shows they have not been changed since, are a different kind of evidence, and that is the reason to keep the record before anyone needs it. Our guide to keeping a contemporaneous record explains why courts treat records that way, and our guide to virtual visitation covers what a court can order about calls and video during an absence.

Documented keeps a dated, sealed record of your own days with a child as they happen: the call that went ahead, the one that did not, the date your orders arrived, the handover, the day you got home. When a court or an attorney asks when the other parent was told and how many calls happened in March, the answer is already written down and ready to hand to your attorney. Learn how it works →

Frequently asked questions

Can a military father get full custody?

Yes, on the same test as any other parent. A court decides custody on the child’s best interest, and federal law says a service member’s absence on deployment, or the possibility of it, cannot be the sole factor in a permanent custody decision. A father in uniform asking for sole custody will be answering the ordinary questions: who has done the care, what the child’s life looks like with each parent, and how a deployment would be covered. A family care plan that matches the court order, and a dated record of the care he has actually provided, are the two documents that answer them.

How does custody work in the military?

Custody is decided by a civilian family court under state law, not by the military. Service adds three things. The Servicemembers Civil Relief Act lets a service member pause a custody case for at least 90 days if duty prevents them appearing. Federal and state law require that a custody change made because of a deployment be temporary, and bar deployment alone from being the reason for a permanent change. And the military requires a family care plan, which organises the child’s care during an absence but does not change the custody order.

Will I lose custody if I join the military?

Not because you joined. Federal law bars a court from treating deployment, or the possibility of deployment, as the sole factor in a permanent custody decision, and most states have a statute on the same point. Joining does change the practical picture, and a court arranging a child’s life will take account of where you will be and when. If you are a single parent or half of a dual-military couple, you will need a family care plan, and it should match your custody order.

What is 51/49 custody in the military?

The numbers describe time: one parent has the child slightly more than half of the time, the other slightly less. No custody statute we read sets that split or attaches anything to it, and a family court decides time on the child’s best interest, not on a formula. If the question behind the search is about a military allowance or benefit, that is a question for your unit’s legal assistance office and your service’s pay rules, not for a custody statute, and this page does not answer it.

Can a custody order be changed while a parent is deployed?

A temporary change can be made to cover the absence, and the parent can take part by electronic means in states that provide for it. A permanent change is harder. Under federal law a court may not treat the deployment as the sole factor, and a service member can apply for a stay of at least 90 days so that the case is not decided in their absence. In California a change made because of a deployment is a temporary order without prejudice, presumed to revert on return. In Texas the temporary order ends by statute when the parent is home.

Does a family care plan override a custody order?

No. A family care plan is a military readiness document. It does not modify a court order, and where the two conflict, the court order controls. If a service member wants the child cared for during a deployment by someone other than what the order provides, that is a request to the court, and the family care plan should be written to match whatever the court orders.
