Missouri courts decide custody based on the best interests of the child, using the terms legal custody and physical custody alongside "parenting time." Since August 28, 2023, Missouri carries a rebuttable presumption that equal or approximately equal parenting time with each parent is in the child's best interests.
How does Missouri decide child custody?
Missouri family courts apply the best interests of the child standard under RSMo 452.375. Circuit courts (family divisions) handle all custody matters, and judges weigh 8 enumerated factors set out in the statute. No parent receives an automatic advantage because of their sex. The statute is gender-neutral and expressly prohibits courts from preferring a parent based on gender. Missouri courts also encourage parents to submit a parenting plan, and courts may adopt an agreed parenting plan as the order of the court if it serves the child's best interests.
Missouri joined a growing list of states in August 2023 when Governor Parson signed SB 35 into law. That legislation added a rebuttable presumption that equal or approximately equal parenting time is in the child's best interests. The presumption changed the starting point for Missouri custody proceedings significantly.
Types of custody in Missouri
Missouri recognizes two categories of custody. Legal custody refers to the authority to make major decisions affecting the child, including decisions about education, healthcare, and religious upbringing. Physical custody refers to where the child lives and the day-to-day parenting-time schedule.
Each type can be awarded as sole (to one parent) or joint (shared between both). Joint legal custody means both parents share decision-making authority. Joint physical custody means the child spends substantial time with each parent according to a parenting plan. Missouri courts use the term "parenting time" extensively to describe each parent's scheduled time with the child, whether custody is joint or sole.
Does Missouri presume joint or 50/50 custody?
Yes. Since August 28, 2023, RSMo 452.375 carries a strong rebuttable presumption that an award of equal or approximately equal parenting time with each parent is in the best interests of the child. This is among the most significant custody law changes in Missouri history.
The presumption applies to original custody determinations. A parent can rebut it by a preponderance of the evidence. Common grounds for rebuttal include: a demonstrated pattern of domestic violence, evidence that equal time would harm the child's adjustment or wellbeing, or geographic considerations that make equal time impractical. Parents may also reach their own agreement on a different parenting schedule, in which case the court will evaluate whether that agreement serves the child's best interests.
It is important to understand that "approximately equal" does not always mean a rigid 50/50 split. Courts retain discretion to order schedules that reflect the child's school, activities, and the practical realities of each family while staying close to equal time.
The best interests factors Missouri courts weigh
RSMo 452.375(2) enumerates 8 factors that Missouri courts must consider when determining custody arrangements:
- The wishes of each parent regarding custody and each parent's proposed parenting plan.
- The need of the child for frequent, continuing, and meaningful contact with both parents and the ability and willingness of each parent to actively perform their functions as mother and father.
- The child's interaction and interrelationship with parents, siblings, and any other person who may significantly affect the child's best interests.
- Which parent is more likely to allow the child frequent, continuing, and meaningful contact with the other parent.
- The child's adjustment to the child's home, school, and community.
- The mental and physical health of all individuals involved, including any history of abuse.
- The intention of either parent to relocate the principal residence of the child.
- The child's uncoerced preference as to the custodial arrangement. Courts consider the child's age and maturity when weighing this factor.
No single factor controls the outcome. Missouri courts consider the totality of the evidence and can give varying weight to each factor depending on the facts of the family.
Relocation: moving with your child in Missouri
RSMo 452.377 governs relocation. A parent who intends to relocate the child's principal residence must provide written notice to every person entitled to custody or visitation at least 60 days before the proposed move. The notice must be sent by certified mail and must include: the new address, the new telephone number, the proposed new residential schedule, and the reasons for the relocation.
The non-moving party has 30 days after receiving the notice to file a written objection with the court. If no timely objection is filed, the court may allow the relocation. If an objection is filed, the court holds a best-interests hearing, examining the statutory factors and the potential impact on the child's relationship with both parents.
Relocation without proper notice can expose the relocating parent to contempt of court and may negatively affect that parent's custody rights. Courts treat unauthorized relocation seriously, particularly when it disrupts the child's established parenting-time schedule.
Changing a custody order in Missouri
RSMo 452.410 sets the standard for modifying an existing Missouri custody order. A court will not modify custody unless it finds that there have been changed circumstances so substantial and continuing that the existing arrangement has become unreasonable. The court must also find that modification is in the child's best interests.
Missouri does not impose a waiting period before a parent may file a modification motion. RSMo 452.410 requires the court to find, based on facts that arose since the prior decree or were unknown to the court at that time, that a change has occurred in the circumstances of the child or the child's custodian, and that modification is necessary to serve the child's best interests.
Examples of circumstances that courts have recognized as substantial and continuing include: a parent's relocation, a significant change in a parent's work schedule, a material change in the child's needs, or a parent's repeated denial of the other parent's parenting time.

If you are facing a custody case in Missouri
If you are dealing with a Missouri custody matter, a few practical steps can strengthen your position. Propose a detailed parenting plan early in the process, covering schedules, holidays, decision-making procedures, and communication protocols. Courts look favorably on parents who come prepared with a workable, child-centered plan.
Document your involvement in the child's daily life: school pickups, medical appointments, extracurricular activities, and day-to-day caregiving. Consistency and engagement weigh heavily in Missouri courts. Focus your communications and conduct on the child's needs rather than the dispute with the other parent, since courts specifically look at which parent is more likely to support the child's relationship with the other parent.
Mediation is strongly encouraged in Missouri and is often required before a contested hearing. Many families reach workable agreements through mediation without the expense and uncertainty of trial. For contested matters involving complex assets, support calculations, or safety concerns, consult a licensed family-law attorney in Missouri.

Frequently Asked Questions
How is child custody determined in Missouri?
Missouri courts apply the best interests of the child standard under RSMo 452.375. Judges weigh 8 enumerated statutory factors, including each parent's proposed parenting plan, the child's need for contact with both parents, the child's adjustment to home and school, and the child's own uncoerced preference. Since 2023, there is also a rebuttable presumption favoring equal or approximately equal parenting time.
Does Missouri favor the mother in custody cases?
No. Missouri law is gender-neutral. Courts may not prefer a parent based on sex, and the old tender-years doctrine (which once favored mothers for young children) has been abolished. Either parent can be awarded sole or joint custody depending on the best interests of the child.
Is Missouri a 50/50 custody state?
Missouri is one of the growing number of states with a rebuttable presumption in favor of equal or approximately equal parenting time (eff. August 28, 2023, SB 35). This means the default starting point leans toward equal time, but a parent can rebut it by a preponderance of evidence showing that equal time is not in the child's best interests. 'Approximately equal' does not always mean a rigid alternating-week schedule.
At what age can a child choose which parent to live with in Missouri?
Missouri has no fixed age at which a child can unilaterally choose. RSMo 452.375 lists the child's uncoerced preference as one of the 8 statutory factors. Courts weigh the child's maturity and reasoning alongside all other factors. A teenager's stated preference carries more weight than that of a young child, but it is never the sole deciding factor.
How do I change a custody order in Missouri?
To modify a Missouri custody order, you must show a change in the circumstances of the child or custodian since the prior decree, or unknown to the court at that time, and that modification is in the child's best interests (RSMo 452.410). Missouri does not impose a waiting period before you can file.
Can a parent move away with the child in Missouri?
Not without proper notice or court approval. RSMo 452.377 requires the relocating parent to give at least 60 days written notice by certified mail, including the new address, phone number, and proposed new parenting schedule. The other parent has 30 days to object. If an objection is filed, the court holds a hearing to determine whether the relocation is in the child's best interests.
What is the difference between legal and physical custody in Missouri?
Legal custody in Missouri refers to the authority to make major decisions about the child's education, healthcare, and religious upbringing. Physical custody refers to where the child lives and the parenting-time schedule. Both can be awarded as sole (to one parent) or joint (shared between both). Joint legal custody is common even when one parent has primary physical custody.

Corrected the modification section: Missouri's custody-modification statute (RSMo 452.410) sets no one-year waiting period; it requires a post-decree change in circumstances and a best-interests finding. Also corrected the relocation factor to cover any proposed move of the child's residence, not only out-of-state moves.
