The equal-parenting-time presumption
Missouri applies a rebuttable presumption that equal or about equal parenting time serves the child's best interest. Both parents begin near the same footing on the schedule.
Rebuttable is the key word: a parent can overcome it with evidence under the statute's factors. But the starting point is roughly equal time.
A parenting plan is required
Section 452.375 needs a proposed parenting plan covering the schedule, decision-making, exchanges and dispute resolution. The court also declares a policy of frequent, continuing and meaningful contact with both parents.
A detailed, workable plan is so both a requirement and strong evidence that you have thought through the child's day.
The best-interest factors
The statute lists eight factors — the parents' wishes and plan, the child's need for a bond with both parents. This parent is more likely to allow contact, the child's adjustment, everyone's health, and any abuse, among them.
The court weighs that kind of evidence, not a parent’s sex.
What the numbers don't decide
The household shares above show where Missouri children live, not how parenting time was ordered. Many plans are agreed rather than litigated.
Use the figures as context only. The presumption and the factors decide the schedule.
Evidence to move off, or defend, equal time
If you seek more or less than equal time, connect the request to exact, dated facts under the factors. Log parenting time, exchanges and missed time, and keep the messages behind each change.
Casewell keeps those entries and files together. So a Missouri lawyer can build the case on a clean record.
Moving has a 60-day clock
Missouri sets out the steps for a move rather than leaving it to goodwill. Under section 452.377, notice of a proposed relocation goes in writing by certified mail, return receipt requested, to any party with custody or visitation rights.
The notice is due at least 60 days before the move. The other parent then has 30 days from receipt to file a motion to stop it.
That timetable is most of the argument. A move made without the notice can be undone, and a parent who objects late has usually lost the point.
How far apart you can live and still share time
There is no mileage limit in Missouri for equal time. What decides it is whether the schedule survives a normal school week.
So the honest test is practical. One school, one drive or bus route, done twice a day, five days a week, by whichever parent has the child that morning. If that breaks, the schedule breaks with it.
Work it out in minutes before you propose it. A log of real journey times, kept across a few normal weeks, answers the objection before it is made.
Before you file in Missouri
Save any current order, track parenting time for a few weeks, and draft your proposed parenting plan.
A Missouri family-law lawyer can weigh it against section 452.375 and your county's practice before filing.

How far can I move with my child in Missouri?
There is no fixed distance. What matters is the process. Section 452.377 asks for written notice by certified mail at least 60 days before a proposed relocation. The other parent then has 30 days from receipt to object.
How far apart can parents live and still have 50/50 in Missouri?
No distance is set in law. The practical limit is the school run. If one parent cannot get the child to the same school on time from their home, an equal schedule usually gives way to something else.
Does Missouri publish a full-custody success rate?
No. Public data does not give a complete percentage of Missouri cases in which mothers or fathers receive sole legal and physical custody. Household statistics describe where children live, not court outcomes.
Do these statistics show that mothers get custody more often in Missouri?
They show the sex of the household householder in a living-arrangement table. They do not show legal custody, parenting-time percentages, the reason for the arrangement, or whether a court was involved.
Can documentation improve my chances of custody?
Yes. Good records can definitely improve your chances. They help you arrive prepared with clear, dated evidence in the right format. They give your lawyer a head start, saving time and fees. They cannot guarantee an outcome, but they can strengthen your case.
What should I record first?
Start with the current arrangement, then record each material change with the date, what was expected, what you observed, the source, the child-related effect, your response, and the outcome. Use Casewell to keep the entry and supporting file together.
