Missouri law starts from a rebuttable presumption that equal or approximately equal parenting time is in the best interests of the child. That has been the starting point since August 2023, and it changed the shape of custody negotiations across Jackson County. It does not mean every case ends 50/50. It means the parent asking for something other than equal time is the one who has to justify it.
Below is what the statute actually requires a judge to consider, and — separately — what tends to decide real cases.
Legal custody and physical custody are different things
People say custody and mean one thing. Missouri means two.
Legal custody is decision-making authority: schooling, medical care, religious upbringing. Joint legal custody means both parents share it.
Physical custody is where the child actually lives and the schedule of time with each parent.
You can have joint legal custody with a very unequal physical schedule, or the reverse. When someone says they were denied custody, the first useful question is always which of the two they mean.
The eight factors, from the statute
Section 452.375 of the Revised Statutes of Missouri requires the court to consider all relevant factors, and lists these:
- The wishes of the child’s parents as to custody and the proposed parenting plan.
- The needs of the child for a frequent, continuing and meaningful relationship with both parents.
- The interaction and interrelationship of the child 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 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 unobstructed input of the child, free of coercion and manipulation.
Factor four is the one people underestimate
Look again at number four: which parent is more likely to allow the child frequent, continuing and meaningful contact with the other parent.
In practice this factor does an enormous amount of work, and it is the one clients most often damage without realising. Every cancelled exchange, every message running down the other parent, every time a child is used to carry information — that is evidence on factor four, and it is evidence against the parent doing it.
The uncomfortable version: a parent who spends the case proving the other parent is unfit frequently proves instead that they are the one unwilling to support the relationship. Judges see this pattern constantly and recognise it quickly.
What about what the child wants?
Factor eight refers to the unobstructed input of the child, free of coercion and manipulation. Two things follow from that wording.
First, there is no magic age at which a child chooses. Missouri does not set one. Input is considered; it does not control.
Second, the phrase free of coercion and manipulation is doing real work. If a child’s stated preference tracks a parent’s talking points, that is usually visible, and it tends to hurt the parent it was meant to help.
Abuse and the history requirement
Factor six specifically includes any history of abuse, and Missouri requires the court to make specific findings where domestic violence or abuse is established. This is not a factor that gets weighed casually alongside the others.
If there is genuine safety concern, it needs to be raised properly, with evidence, and early. If there is not, alleging it as leverage is one of the most damaging things a parent can do to their own case.
The parenting plan matters more than the argument
Missouri requires a proposed parenting plan. Many parents treat it as paperwork. Judges do not.
A plan that is specific, workable and clearly built around the child’s actual schedule tells a judge something about the parent who wrote it. A plan that is vague, or that is transparently designed to inconvenience the other parent, tells them something too.
Get the detail right: holidays, school breaks, exchange locations and times, transport, how a schedule change gets requested, how decisions get made when the parents disagree. The disputes that come back to court two years later are almost always about something the plan left blank.
Common questions
Does Missouri favour mothers?
No. The statute directs the court to the child’s best interests using the factors above, and since 2023 the starting point is a presumption of equal or approximately equal parenting time. That presumption is not gendered.
Can we just agree and skip the fight?
Yes, and it is usually the better outcome. Missouri contemplates parents reaching agreement, and an agreed plan the court approves avoids the cost, delay and unpredictability of letting someone else decide. The caveat is that an agreement made badly — vague, or signed to end an argument — becomes the thing you are stuck with.
Can custody be changed later?
Modification is possible, but it is not a rerun of the original case. Missouri requires a substantial change in circumstances, which is a real threshold and not simply a change of mind or a new job.
My ex will not follow the schedule. What do I do?
Document it, calmly and factually, and do not respond by withholding time yourself — that puts you on the wrong side of factor four. Enforcement is available through the court, and a clear record of the pattern is what makes it work.
What if one parent wants to move away?
Relocation is factor seven and Missouri has specific notice requirements around moving a child’s principal residence. It is not something to do first and disclose later; handled that way it usually goes badly for the parent who moved.
