A deployment generally leads only to temporary custody changes. The arrangement you had before is designed to come back when you return.
A PCS move where your family is allowed to come along is usually treated as an ordinary relocation. State notice deadlines and a best-interests review apply, and nothing reverts automatically.
A Family Care Plan doesn't override a custody order. Only a state court decides custody.
How does military child custody work?
Military child custody is decided under the same state family law that applies to civilian parents, with an added layer of federal protection for deployments. There's no separate "military custody" court. The judge who handles your case applies your state's best-interests standard.
What federal law adds is a floor. Under the Servicemembers Civil Relief Act's custody provision, a court deciding a permanent custody change can't treat your deployment as the sole factor in what's best for your child. Neither can the mere possibility that you'll deploy. Serving in the military isn't, on its own, a reason to lose custody. Your availability, your care plan, and your history with your child can still matter, the same as for any other parent.
Deployment vs. PCS: why courts treat them differently
The distinction that shapes almost everything else: the law treats a deployment and a PCS move as two different events.
Federal law defines "deployment" as a move or mobilization of more than 60 days and up to 540 days (50 U.S.C. § 3938(e)). The orders have to be unaccompanied, deny dependents authorization, or otherwise not allow your family to relocate there. A standard "PCS," or permanent change of station, where your spouse and kids are authorized to come with you, doesn't fit that definition. It's a move.
This is spelled out explicitly in several of the states where Marble is active:
Florida — the military time-sharing statute doesn't apply to a permanent change-of-station move; that falls under the state's general relocation statute instead.
New York — deployment protections don't cover permanent duty-station reassignments.
Maryland — deployment is defined as duty that's unaccompanied or classified as remote.
Deployment
PCS move (family can come)
Typical orders
Unaccompanied, no dependents authorized
Accompanied, dependents authorized
How long
More than 60 days, up to 540 days (federal definition)
A long-term assignment
Legal track
Temporary order for the deployment period
Relocation request or custody modification
When it ends
Prior custody order generally comes back
The new arrangement becomes the order
Notice rules
Deployment-specific (some states require notice within days of orders)
State relocation notice rules, often 30 to 90 days
Who has to justify it
Deployment alone can't be the sole reason for a permanent change
Often the parent seeking the move, depending on the state
Many parents assume a PCS always means relocation rules. But an unaccompanied PCS, such as a remote or dependent-restricted tour, can fall under deployment rules instead. The definitions turn on whether your family can come, not on what the orders are called.
What happens to custody when a military parent deploys?
In most military deployment child custody cases, a court can adjust custody only temporarily while you're deployed.
Temporary orders end when you get back
Federal law requires any temporary order based solely on a deployment to end no later than the deployment justifies (§ 3938(a)). Many states go further:
Texas — temporary deployment orders end when you return to your usual residence, and the prior order governs again (Tex. Fam. Code § 153.702(d)).
California — deployment-related orders are temporary, and presumptively revert to the prior order once you're back.
Handing off your parenting time
Some states also let you hand your parenting time to someone else while you're gone. That's often called "delegated" or "substitute" military visitation. A court lets a person your child knows, such as a grandparent or stepparent, use some or all of your time.
In Illinois, for example, a court may let a deployed parent designate "a person known to the child to exercise reasonable substitute visitation." That's allowed when it's in the child's best interests. Texas uses the term "designated person" for the same idea.
Other deployment protections
Makeup time
In Texas, a parent without the right to decide the child's primary residence can ask the court, within 90 days after returning, to award extra time for what was missed (§ 153.709).
Remote hearings
Texas, California, Arizona, and Florida all allow electronic testimony or expedited hearings when military duties affect your ability to appear.
A pause in the case
If duty keeps you from participating, the SCRA lets you request a stay of at least 90 days, backed by a letter from your commanding officer (50 U.S.C. § 3932). A stay delays the case. It doesn't dismiss it, and the same protection is available if you're going through a military divorce at the same time.
Does a Family Care Plan override a custody order?
No. A "Family Care Plan" is the military's required document naming who cares for your child while you're away. It's an administrative requirement, not a court order. The Department of Defense's own instruction on Family Care Plans tells commanders to inform members of "the overriding authority of State courts to determine child custody arrangements, notwithstanding a family care plan."
The same instruction requires you to try, "to the greatest extent possible," to inform your child's other parent of your absence and to get their consent before naming a third party as caregiver. A plan that hands your child to your mother while your co-parent has court-ordered time can put you in violation of your custody order.
The fix is to make your Family Care Plan and your parenting plan say the same thing. Put any delegation in front of the court if your state allows it. A power of attorney for your child can handle day-to-day decisions like school and medical care, but it doesn't change custody either.
What happens to custody when you get PCS orders?
Military relocation and child custody law starts from one rule: your custody order stays exactly as it is until a court changes it. It stays the same unless you and your co-parent formally agree otherwise. Orders from the military don't give you permission to move your child.
Your three options
Agree in writing with your co-parent on a new schedule and submit it to the court. Florida, for example, lets a court approve a written relocation agreement without a hearing unless someone asks for one.
Ask the court for permission to relocate, or to modify custody, if your co-parent won't agree.
Build a long-distance parenting plan that gives the parent who stays behind longer blocks of time, such as summers and extended holidays.
Timing: notice and how long it takes
Watch the notice deadlines. Most states where Marble is active set a notice period for moves with a child, ranging from 30 to 90 days. Some count from when you first learn of the move rather than when it happens. The state table below lists each rule.
It also helps to plan for how long a contested relocation takes. Across 50 completed Florida relocation petitions handled by attorneys working with Marble, the median case ran about 7 weeks, and 1 in 4 took about 4 months or longer. Another 18 relocation petitions from the same period are still open, some for several years, so they aren't included in this timeline.
Which state's court decides?
The "UCCJEA" is the uniform law nearly every state uses to decide which court has authority over a custody case. Under it, the state that issued your order generally keeps that authority until the child and both parents no longer live there. Texas's version is typical (Tex. Fam. Code § 152.202). Moving to a new duty station doesn't automatically let the new state's courts take over your case.
When you get orders, gather these first:
Your current custody order, including the case number and the court that issued it. These are among the details people most often can't find quickly.
Your orders, and whether dependents are authorized.
Your Family Care Plan.
A proposed schedule, including how you'll use leave.
The notice deadline in your order or your state's statute.
What if you're the parent who isn't in the military?
Your co-parent's PCS orders don't let them move your child without your agreement or a court order. If they ask the court for permission, you generally have a window to object. In Florida, that's 20 days after being served with the petition; in Arizona, it's 30 days after receiving notice.
The military can't award custody, and neither can a commander. If a Family Care Plan names someone else to care for your child during a deployment, remember that it doesn't override your court-ordered time.
Can a military parent get full or primary custody?
Yes. Courts apply the same best-interests test to military and civilian parents, and deployment can't be the only reason to deny you custody. What courts often look at is practical:
Who handles day-to-day care
How stable each home is
How realistic your plan is for times you're away
A detailed care plan and a record of steady involvement can carry real weight.

Terms differ by state: Florida uses "time-sharing," Arizona uses "legal decision-making" and "parenting time," and Illinois uses "allocation of parental responsibilities." Deadlines and definitions vary and change over time, so check with a local attorney before relying on them.
How a child custody lawyer can help
An attorney's first job is usually to figure out which set of rules your orders trigger: deployment protections, relocation law, or both. From there, a child custody lawyer can:
File for temporary orders or a delegation of your parenting time before you leave
Draft a relocation notice or petition that meets your state's deadline
Negotiate a long-distance or post-deployment schedule
Handle hearings remotely when you can't be there
If your co-parent is the one moving, an attorney can file your objection on time and ask the court for a schedule that keeps you involved.
Attorneys with Marble work at fixed, upfront prices, so you know the cost of each step before it starts. If you're deployed or facing a PCS move in the middle of a custody case, an attorney can walk you through your options for your parenting time. Texas cases carry their own procedural steps, which Marble's Texas child custody page covers in more detail.
Final thoughts
Military child custody comes down to one early question: is this a deployment or a move? A deployment usually brings temporary changes the law is built to undo. A PCS move usually means a relocation case with deadlines, and the sooner you start, the more options you tend to have. Pull your custody order the day your orders arrive.
