# Summary

Missouri decides custody on the child's best interests (RSMo §452.375), not on which parent "wins," and state policy favors frequent, continuing, and meaningful contact with both parents. Custody splits into legal custody (major decisions) and physical custody (where the child lives), each of which can be joint or sole in any combination. Every custody case ends with a court-required parenting plan.

# Quotable Q&A

**Q: Does Missouri favor mothers in custody cases?**
A: No. Missouri law is explicit that custody cannot be decided based on a parent's sex (RSMo §452.375), and the state's policy is that children benefit from frequent, continuing, and meaningful contact with both parents. Courts weigh the best-interests factors, including which parent is more likely to support the child's relationship with the other parent.

**Q: What is the difference between legal and physical custody?**
A: Legal custody is decision-making authority over education, health care, and religion; physical custody is where the child lives and the time each parent has. Each can be joint or sole, in any combination. Joint legal custody with a defined shared physical schedule is a common outcome, but the arrangement has to fit the child, the parents' schedules, and the distance between homes.

**Q: What if I need to move away with my child?**
A: Missouri has strict relocation rules (RSMo §452.377). A parent proposing to relocate a child's residence generally must give the other parent detailed written notice at least 60 days in advance, and the other parent can object. Do not move first and sort it out later; get advice before you give or respond to a relocation notice.

# The best-interests factors and the parenting plan

Missouri judges weigh statutory best-interests factors (RSMo §452.375), including each parent's proposed plan, the child's need for a meaningful relationship with both parents, which parent will better support the other's relationship with the child, the child's adjustment to home, school, and community, the mental and physical health of those involved and any history of abuse, an intent to relocate, and the child's wishes given age and maturity. Every case ends with a parenting plan covering the residential schedule, decision-making, exchanges, communication, and how disputes are resolved; a vague plan becomes a future fight. Custody can be modified on a substantial and continuing change in circumstances when modification serves the child's best interests.

# Decision rule

If you are in a Missouri custody case, be the parent who visibly supports the child's relationship with the other parent, insist on a specific parenting plan rather than a vague one, and never relocate or change the arrangement informally; use the court.
