US FederalCan military service affect child custody or support proceedings?
Federal law does not automatically change child custody or support due to military service, but it provides protections against unfair jurisdictional changes and ensures full faith and credit for valid custody orders across states.
What the Law Says
Federal law does not set custody or support standards for military families—but it ensures that valid state custody determinations are respected across state lines. The Parental Kidnapping Prevention Act (PKPA), codified at 28 U.S.C. § 1738A, establishes uniform rules for interstate custody jurisdiction and enforcement.
The PKPA does not define custody rights or modify support obligations based on military status. Instead, it prevents conflicting custody orders by requiring states to give 'full faith and credit' to valid custody determinations made by other states’ courts.
It sets priority rules for which state has jurisdiction—generally the child’s 'home state' (where the child lived with a parent for at least six consecutive months)—and bars a second state from modifying an existing order unless the original court no longer has jurisdiction or declines to exercise it.
Importantly, the PKPA applies equally to all parents—including service members—and does not create exceptions or special rules for deployment, reassignment, or active duty.

What to Do
If you’re a service member facing custody proceedings, file in your home state—or where the child has resided for six+ months—if possible.
Object promptly if the other parent tries to file in a new state solely because of your deployment or PCS move.
Provide documentation (orders, duty stations, leave records) to prove your child’s home state and your continued involvement.
Request that courts consider deployment as a temporary factor—not grounds to alter custody permanently.
Consult a legal assistance attorney through your installation’s Judge Advocate General (JAG) office for state-specific strategy.
