Child custody, explained simply
Courts decide custody based on what’s best for the child. Legal custody is who makes big decisions; physical custody is where the child lives. Parents can agree on a parenting plan, often with a mediator; if they can’t, a judge decides. Child support is set separately, usually by a state formula.
Your checklist

The main rule
Courts decide custody based on what’s best for the child.
Two kinds of custody
- Legal custody: who makes big decisions, like school, religion and health care.
- Physical custody: where the child lives day to day.
Either can be shared (joint) or given mostly to one parent.
The parenting plan
It sets the schedule for school days, weekends, holidays and summer, and how you’ll make decisions and handle changes.
Agree if you can
Many courts send parents to mediation. Agreements are often faster, cheaper and easier on children.
If you can’t agree
A judge decides, looking at the child’s needs, each parent’s home, and who has been caring for the child. Older children’s wishes may count.
Child support
Support is separate and usually set by a state formula based on income and parenting time.
If there’s a safety concern, a move to another state, or the other parent has a lawyer, talk to a family lawyer early.
Common questions
At what age can a child choose?
There’s no single age everywhere. Judges may consider an older child’s wishes, but the decision is based on the child’s best interests.
Can custody be changed later?
Yes. Usually you ask the court and show that circumstances have changed.
