How custody is decided in Missouri ↓

Since August 28, 2023, Missouri law has carried a rebuttable presumption that equal or approximately equal parenting time is in a child’s best interests. That changed the negotiating baseline in every custody case in the state, and a parent who is still working from the old assumptions — that mothers get primary custody, that every-other-weekend is standard — is negotiating against a rule that no longer exists. This page explains what the court decides, what the presumption does and does not do, what the statute requires a parenting plan to contain, and why the plan you write is worth more than the one a judge would impose. Most custody cases should settle. We work to settle yours, and we try it if we have to.

The vocabulary

Custody is two separate decisions.

Legal custody

Decision-making authority over the child’s health, education and welfare. RSMo § 452.375 defines joint legal custody as parents sharing “the decision-making rights, responsibilities, and authority relating to the health, education and welfare of the child.” Joint legal custody is the norm; sole legal custody generally requires a reason the court will credit.

Physical custody

Where the child actually lives and when. Joint physical custody means each parent has “significant, but not necessarily equal, periods of time” with the child. Since 2023 the presumption is that those periods should be equal or approximately equal, unless it is rebutted.

Visitation

The term Missouri uses for the parenting time of a parent who does not have physical custody. Under RSMo § 452.400 a non-custodial parent is entitled to reasonable visitation unless the court finds it would endanger the child. See visitation and parenting time.

The parenting plan

The document that turns all of the above into a schedule. Every Missouri custody judgment must include a specific written parenting plan under RSMo § 452.310, and if the parents do not submit one the court imposes one.

The presumption

What equal parenting time means — and what it does not.

The starting point is fifty-fifty. RSMo § 452.375 now provides: “There shall be a rebuttable presumption that an award of equal or approximately equal parenting time to each parent is in the best interests of the child.” The presumption “is rebuttable only by a preponderance of the evidence in accordance with all relevant factors” — the statutory best-interest factors — and it is also rebutted where the parents have reached an agreement on all custody issues, or where the court finds a pattern of domestic violence.

It is a presumption, not a mandate. A parent asking for a schedule well away from equal time needs evidence under the statutory factors: which parent is more likely to allow the child frequent, continuing and meaningful contact with the other; the child’s adjustment to home, school and community; the mental and physical health of everyone involved, including any history of abuse; the intention of either parent to relocate; and the child’s own wishes, expressed without coercion. Distance between homes, work schedules and a very young child are the practical facts that most often move a court off equal time.

Agreement rebuts it too. Two parents who agree on a schedule that is not equal — because one travels for work, because the school is across town from one home — can present that agreement, and the court reviews it for the child’s best interests rather than measuring it against the presumption. That is one more reason the agreed plan is usually the better plan.

No preference by sex or age. The statute states that no preference may be given to either parent because of that parent’s age, sex or financial status, nor because of the age or sex of the child. Custody judgments where the parents disagree must include written findings on the specific factors that made the arrangement ordered the one in the child’s best interests.

The court decides custody in a fixed order. Under RSMo § 452.375 the court considers, in order: joint physical and joint legal custody to both parents; joint physical custody with sole legal custody to one parent; joint legal custody with sole physical custody to one parent; sole custody to either parent; and, only where the court finds each parent unfit, unsuitable or unable to be a custodian, or the welfare of the child requires it, custody or visitation to a third party. That last option is how a grandparent or step-parent ends up with a child, and the bar is high.

The parenting plan

The document that prevents the next case.

The regular schedule

RSMo § 452.310 requires “a specific written schedule detailing the custody, visitation and residential time for each child with each party.” That means the weekday and weekend rotation, with exchange times and places, and who drives.

Holidays, breaks and birthdays

Major holidays, school holidays, the child’s birthday, Mother’s Day and Father’s Day, summer and winter breaks — set out year by year so that nobody argues about whose turn it is. “Alternating” is not a schedule.

Decision-making

A specific written plan for legal custody: how decisions about education, medical, dental and health care, extracurricular activities and child care are made, how the parents communicate, and what happens when they deadlock.

Communication and access

Telephone and electronic contact between the child and the parent the child is not with, and between the households. Both parents keep access to school and medical records under RSMo § 452.375 unless a court order says otherwise.

Money

The suggested child support under Form 14, and how health insurance, uncovered medical costs, educational and extraordinary expenses, child care and transportation are allocated between the parents.

Changes and dispute resolution

The procedure for a temporary variation to the schedule, and what the parents will do — mediation, usually — before either of them files a motion. The court publishes a template as Form CAFC501; a good plan uses it as a floor, not a ceiling.

How this works

How a custody case actually moves.

Get the schedule straight

What the arrangement is in practice today — not on paper. Who does school drop-off, who takes the child to the doctor, where the child sleeps on which nights. The existing routine is frequently the strongest evidence of what the plan should be.

Know what a judge would do

Equal time is presumed. Form 14 sets a presumed support figure. A plan that departs from either needs a reason. Knowing the realistic range is what makes a negotiation real.

Exchange plans within thirty days

Each parent files a proposed parenting plan within thirty days of service or entry of appearance. Where the plans overlap, the case is mostly done. Where they differ, the differences are the case.

Mediate

Missouri’s declared public policy is to resolve disputes about children through alternative dispute resolution, and many circuits will order mediation before a trial setting. A mediated plan two parents wrote is approved far more often than not.

If it does not settle

A guardian ad litem may be appointed under RSMo § 452.423. The court may interview the child in chambers under RSMo § 452.385. Evidence is presented on the statutory factors, and the judgment includes written findings on them.

Live with it, and enforce it

A judgment is only as good as the schedule it creates. If the other parent does not follow it, Missouri gives you a fast remedy — the family access motion under RSMo § 452.400 — and a persistent refusal can itself support a modification.

He writes the plan with the next fight in mind.

Derek R. Haake, Attorney

Derek drafts parenting plans and marital settlement agreements, and litigates contested custody when agreement is not available. Drafting after years of watching agreements fail is a different exercise: the plans written here say who has the first week of summer, what happens when Christmas falls on a Tuesday, and who decides when the parents disagree about a therapist.

As a partner at Howard Haake from 2014 to 2022 he handled probate, contested wills and trusts, and civil litigation — contested proceedings about families and money, which is what a fought custody case is. He also holds an MBA and spent three years at Bank of America Private Bank valuing and transferring family assets, which is why the support and property side of a custody case does not get handed to someone else.

None of which makes settlement the soft option. It is the position you can hold precisely because the case has been prepared as if it will be tried.

Common questions

Custody in Missouri, answered.

Does the equal-parenting-time presumption mean I will get 50/50?

It means the court starts there. RSMo § 452.375 provides a rebuttable presumption that an award of equal or approximately equal parenting time to each parent is in the child’s best interests, rebuttable only by a preponderance of the evidence under the statutory factors. So a parent who wants equal time no longer has to justify it; a parent who wants something else does.

The facts that most often rebut it are practical. Parents who live forty minutes apart cannot alternate school weeks. A parent who works nights or travels cannot exercise equal overnights. A nursing infant is a different case from a twelve-year-old. And the factors that have always mattered still do — a history of abuse, a parent who undermines the child’s relationship with the other parent, a parent who intends to relocate.

“Approximately equal” also covers a range. A 2-2-5-5 rotation, alternating weeks, and a schedule that gives one parent a few more overnights across the year can all satisfy the presumption. The practical question is usually which equal-ish schedule fits the child’s school and the parents’ work, not whether equal applies.

What is the difference between joint and sole custody?

Joint legal custody means both parents share decision-making about health, education and welfare; sole legal custody gives that authority to one parent. Joint physical custody means the child has significant periods with each parent; sole physical custody means the child resides with one parent and the other has visitation. The four combinations are considered in the order set out in RSMo § 452.375, with joint legal and joint physical first.

Joint legal custody is the usual outcome, and a court awarding sole legal custody will generally need to find that the parents cannot communicate or cooperate on decisions to the point that shared authority would harm the child. Two parents who dislike each other but manage to exchange emails about the pediatrician usually have joint legal custody.

Because a parent with legal custody may determine the child’s upbringing, including education, health care and religious training, RSMo § 452.405 adds a limit: the legal custodian “shall not exercise legal custody in such a way as to significantly and detrimentally impact the other parent’s visitation or custody rights.” Decision-making does not include scheduling the other parent out of the child’s life.

What factors does the court consider?

RSMo § 452.375 lists them: the wishes of the parents and their proposed parenting plans; the child’s need for frequent, continuing and meaningful contact with both parents, and each parent’s ability and willingness to perform their functions; the child’s interaction with parents, siblings and anyone else who significantly affects the child’s interests; which parent is more likely to allow the child frequent, continuing and meaningful contact with the other; the child’s adjustment to home, school and community; the mental and physical health of everyone involved, including any history of abuse; the intention of either parent to relocate the child’s principal residence; and the unobstructed input of the child, free of coercion and manipulation.

Where the parents have not agreed, the judgment must include written findings on the specific relevant factors that made the arrangement ordered the one in the child’s best interests. Where domestic violence has occurred, the court must make specific findings that the arrangement ordered best protects the child and the parent who was the victim.

The factor that decides more cases than any other is the fourth one — which parent is more likely to allow contact with the other. A parent who withholds the child, disparages the other parent, or refuses to communicate is proving the other side’s case.

Does my child get to choose?

No, but the child’s wishes are one of the statutory factors, and they carry more weight as the child gets older. Missouri does not set an age at which a child’s preference controls, and a court is not bound by a teenager’s stated wish — particularly where the wish is for the parent with fewer rules.

The court hears the child’s wishes carefully. Under RSMo § 452.385 the judge may interview the child in chambers rather than in open court; counsel must be permitted to be present and to participate, and a record of the interview is made part of the case record. Where a guardian ad litem has been appointed, the GAL interviews the child and reports the child’s wishes, feelings, attachments and attitudes to the court.

What a court will not tolerate is a parent coaching the child. The statute refers to the “unobstructed input of a child, free of coercion and manipulation,” and evidence that a parent has been scripting the child’s preference tends to reflect badly on that parent rather than well.

What is a guardian ad litem and will one be appointed?

A guardian ad litem is a lawyer appointed by the court to represent the child’s interests — not either parent’s. Under RSMo § 452.423 the court may appoint one in any proceeding in which custody, visitation or support of a child is contested, and must appoint one in any proceeding in which child abuse or neglect is alleged.

The GAL is the child’s legal representative: they may examine and cross-examine witnesses, offer testimony, and are directed to interview people with contact with the child to ascertain the child’s wishes, feelings, attachments and attitudes. A GAL’s recommendation carries considerable weight in practice, and each party may disqualify one appointed GAL within ten days of the appointment.

The parties pay the GAL’s fee, which the court sets and may allocate between them, and it is a real cost — one of several concrete reasons an agreed parenting plan is cheaper than a fought one.

Can the other parent move away with our child?

Not without following the relocation statute, and this is one of the most consequential traps in Missouri family law. RSMo § 452.377 defines relocation as a change in the child’s principal residence for ninety days or more — with no distance threshold, so a move across the county is covered as well as a move across the state line.

The relocating parent must give written notice by certified mail, return receipt requested, at least sixty days before the move, stating the new address, the date of the move, the specific reasons for it, and a proposed revised custody schedule. The other parent has thirty days from receipt to file a motion objecting; the relocating parent has fourteen days to reply. The parent seeking to relocate bears the burden of proving the move is in good faith and in the child’s best interests.

Moving without notice is a factor in whether custody should be modified, a basis for an order returning the child, and grounds for an award of expenses and attorney’s fees. Under RSMo § 452.411, a parent’s move to another state is deemed a change of circumstances for a modification motion. If a move is on your horizon, get advice before you sign a lease.

We were never married. How is custody decided?

On the same standard, in a different case. An unmarried parent who has signed the birth certificate or an acknowledgment of paternity is the child’s legal parent, but has no custody order and no enforceable schedule until a court enters one. Many unmarried fathers learn this at the moment the relationship ends.

A paternity action under Missouri’s Uniform Parentage Act establishes parentage where it is disputed — with genetic testing if necessary — and then sets custody, a parenting plan and child support in the same case, applying RSMo § 452.375 and the equal-parenting-time presumption exactly as a divorce would. Where the parents agree, the whole thing can be presented as a consent judgment. Our family law overview covers paternity in more detail.

Can a grandparent or step-parent get custody?

Custody, rarely; visitation, sometimes. Third-party custody is the last option on the list in RSMo § 452.375, available only where the court finds each parent unfit, unsuitable or unable to be a custodian, or that the welfare of the child requires it. A grandparent who has been raising the child for years while the parents were absent is the typical case; a grandparent who thinks they would do a better job is not.

Grandparent visitation is a separate statute, RSMo § 452.402. A grandparent may petition where visitation has been unreasonably denied for more than sixty days and the parents have filed for dissolution, or one parent has died and the surviving parent denies visitation, or the child lived with the grandparent for at least six months in the prior two years. A grandparent may not file where the parents are married to each other and living together with the child. See visitation.

Which state’s court decides custody if we live in different states?

The child’s home state. Missouri has adopted the Uniform Child Custody Jurisdiction and Enforcement Act, and under RSMo § 452.740 a Missouri court has jurisdiction to make an initial custody determination if Missouri is the child’s home state on the date the case is filed, or was the home state within six months before filing and a parent still lives here. The home state is where the child has lived with a parent for at least six consecutive months.

Once a Missouri court has entered a custody order, it keeps exclusive, continuing jurisdiction under RSMo § 452.745 until neither the child nor either parent lives in Missouri, or a court finds the child no longer has a significant connection here. A parent who moves to another state and files there is usually filing in the wrong court.

The practical point: file first, in the right state, before the other parent establishes a new home state by the passage of six months.

What if the other parent has been abusive?

The statute addresses it directly. RSMo § 452.375 makes the mental and physical health of all individuals involved, “including any history of abuse of any individuals involved,” a best-interest factor. The equal-parenting-time presumption is rebutted by a finding of a pattern of domestic violence. And where domestic violence has occurred, the judgment must include specific findings that the custody arrangement best protects the child and the parent who was the victim.

On the visitation side, RSMo § 452.400 requires the court to consider evidence of domestic violence, permits visitation to be restricted or supervised where it would endanger the child, and bars unsupervised visitation altogether for a parent convicted of certain felonies in which a child was the victim. Where child abuse or neglect is alleged, appointment of a guardian ad litem is mandatory.

What the court needs is evidence — police reports, medical records, protective orders, witnesses, contemporaneous messages. An allegation without it tends to be weighed against the parent making it. If you or your child are in danger now, an order of protection under chapter 455 is available immediately, separately from the custody case.

Do we have to take a parenting class?

In most cases, yes. RSMo § 452.372 directs the court in any dissolution or legal separation involving a minor child to order the parties to attend educational sessions about the effects of divorce on children, unless it waives the requirement for good cause. The statute lists uncontested custody as an example of good cause, but many circuits require the class by local rule regardless. It is short, inexpensive, and usually completed online.

The same section permits the court to order parents in a custody or visitation dispute into an alternative dispute resolution program. Mediation is non-binding: the mediator decides nothing, you keep your lawyer, and you keep the right to try the case.

Can a custody order be changed later?

Yes, but the standard is deliberately demanding. Under RSMo § 452.410 the court may modify a custody order only on facts that have arisen since the prior decree or were unknown to the court at the time, and only if it finds that a change has occurred in the circumstances of the child or the custodian and that modification is necessary to serve the child’s best interests. Both halves matter.

Visitation is easier to adjust: RSMo § 452.400 allows a visitation order to be modified whenever modification would serve the child’s best interests, without the change-of-circumstances showing. A new parenting plan is required with any motion to modify. See modifications.

What should I bring to the consultation?

Any existing court order or parenting plan; a short written description of the schedule that actually happens now; the child’s school and activity calendar; both parents’ work schedules and addresses; recent pay stubs and last year’s tax return if you have them, for the Form 14; and any protective orders, police reports or messages that bear on safety or on the other parent’s willingness to cooperate.

If you have been served with a petition or a motion, bring it and say when you were served. The proposed parenting plan is due within thirty days, and that deadline does not wait for a convenient appointment.
