Missouri Child Custody Agreement

Introduction

Key Things to Know

1. 1

   Missouri presumes equal parenting time, and your agreement is one of the two ways past it. Mo. Rev. Stat. 452.375.2 provides a rebuttable presumption that equal or approximately equal parenting time is in the best interests of the child, rebuttable only by a preponderance of the evidence. The statute then provides that the presumption may be rebutted if the court finds that the parents have reached an agreement on all issues related to custody, or if the court finds that a pattern of domestic violence has occurred. Whether that helps or hurts depends entirely on what the two of you agreed to, since the agreement is what lets a court approve a schedule that is not equal.

2. 2

   Agreeing on everything also removes the court's written-findings duty. The direction in Mo. Rev. Stat. 452.375.2 to consider all relevant factors and enter written findings of fact and conclusions of law is framed to apply when the parties have not reached an agreement on all issues related to custody, and 452.375.6 attaches the same duty if the parties have not agreed to a custodial arrangement, or the court determines the arrangement is not in the best interest of the child. Note the word all in both provisions. An arrangement that settles the schedule but leaves a decision-making question open is not an agreement on all issues.

3. 3

   Your agreement is a proposal to the court, not a contract that binds it. Mo. Rev. Stat. 452.325.1 lets parents put custody, support, and visitation into a written separation agreement, and 452.325.2 then makes the agreement binding on the court except terms providing for the custody, support, and visitation of children. Mo. Rev. Stat. 452.375.9 says the same thing from the other side: in all cases the custody plan approved and ordered by the court is in the court's discretion and must be in the best interest of the child. Two related limits are worth knowing: under 452.325.4(2) custody terms are set out in the decree even where the parents ask that the rest of their agreement not be, and under 452.325.6 parents cannot use the agreement to preclude or limit modification of terms concerning custody or visitation.

4. 4

   A parenting plan is required at both ends of the case. Under Mo. Rev. Stat. 452.310.8, the petitioner and respondent shall submit a proposed parenting plan, either individually or jointly, within thirty days after service of process or the filing of the entry of appearance, whichever occurs first. Under 452.375.9, any judgment providing for custody shall include a specific written parenting plan containing the 452.310.8 terms, which may be the plan the parties submitted. A plan is not required under 452.310.11 for a child over eighteen for whom custody, visitation, or support is being established or modified.

5. 5

   The prescribed contents are unusually detailed and were amended effective August 28, 2026. Mo. Rev. Stat. 452.310.8 runs to twenty-five line items under three headings: a residential schedule, a written plan for legal custody and decision-making, and how the child's expenses will be paid. The named items include major holidays and which parent has each one in each year, school holidays, the child's birthday, Mother's Day and Father's Day, weekday and weekend schedules, times and places for transfer, sharing transportation duties, telephone access times, procedures for requesting a temporary variation, education and medical decisions, extracurricular activities, child care providers, and a dispute resolution procedure. The list is a floor rather than a ceiling, and 452.375.11 forbids a court from adopting any local rule, form, or practice that requires a standardized or default parenting plan.

6. 6

   If the court rejects what you filed, it has to say why in writing. Mo. Rev. Stat. 452.375.6 provides that if a proposed custodial arrangement is rejected, the court shall include a written finding in the judgment or order detailing the specific relevant factors resulting in the rejection. The factors it would work from are the eight at 452.375.2(1) through (8), covering the parents' wishes and their proposed plans, the child's need for frequent, continuing, and meaningful relationships with both parents, the child's interaction with parents, siblings, and other significant people, which parent is more likely to allow 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, either parent's intention to relocate the child's principal residence, and the unobstructed input of the child free of coercion and manipulation. The list is prefaced by including, but not limited to, so it is open.

7. 7

   Domestic violence is a mandatory consideration in Missouri rather than a presumption against custody. A history of abuse sits in factor (6) at Mo. Rev. Stat. 452.375.2, and the same provision requires the court to enter written findings of fact and conclusions of law if it finds that awarding custody to an abusive parent is in the best interest of the child. Both 452.375.2(6) and 452.375.15 direct that custody and visitation rights be ordered in a manner that best protects the child and the parent or other family or household member who is the victim of domestic violence from any further harm, and since 2024 a found pattern of domestic violence is one of the two named grounds for rebutting the equal parenting time presumption. Where there has been abuse or a protective order, this is a situation to raise with a lawyer rather than settle on a form.

Missouri Requirements for Child Custody Agreement

• Equal Parenting Time Presumption, Mo. Rev. Stat. 452.375.2

  Since August 28, 2024 there is a rebuttable presumption that equal or approximately equal parenting time is in the child's best interests, rebuttable only by a preponderance of the evidence. The statute names two grounds for rebutting it: a finding that the parents have reached an agreement on all issues related to custody, and a finding that a pattern of domestic violence has occurred.

• Agreement on All Custody Issues, Mo. Rev. Stat. 452.375.2 and 452.375.6

  The duty to consider all relevant factors and enter written findings of fact and conclusions of law applies when the parties have not reached an agreement on all issues related to custody, and again if the parties have not agreed to a custodial arrangement. State expressly that the agreement covers every custody issue, since a partial agreement does not meet the wording.

• Custody Terms Not Binding on the Court, Mo. Rev. Stat. 452.325.2

  The terms of a separation agreement are binding on the court except terms providing for the custody, support, and visitation of children. The custody portion of what the parents sign is a proposal for the court to approve, not a contract that fixes the outcome.

• Custody Terms in the Decree, Mo. Rev. Stat. 452.325.4(2) and 452.325.6

  Even where the parties direct that their agreement's terms not be set out in the decree, only the terms concerning child support, custody, and visitation shall be set out there, so custody cannot be kept out of the judgment. The decree may limit modification of decreed terms if the agreement so provides, except for terms concerning support, custody, or visitation.

• Proposed Parenting Plan Deadline, Mo. Rev. Stat. 452.310.8 and 452.310.9

  The petitioner and respondent shall submit a proposed parenting plan, individually or jointly, within thirty days after service of process or the filing of the entry of appearance, whichever occurs first. Where the plans differ or a party does not file, the court enters a temporary order containing a plan, so agreeing parents benefit from filing a single joint plan on time.

• Prescribed Plan Contents, Mo. Rev. Stat. 452.310.8

  The plan must include twenty-five enumerated items under three headings: a residential schedule reaching holidays, school holidays, the child's birthday, Mother's Day and Father's Day, transfer times and places, transportation, telephone access, temporary variations, and any requested access restrictions; a written legal custody plan covering education, health care, extracurricular activities, child care providers, communication, and dispute resolution; and how the child's expenses are paid. The section was amended effective August 28, 2026 and the list is a floor rather than a ceiling.

• Parenting Plan in the Judgment, Mo. Rev. Stat. 452.375.9 and 452.375.11

  Any judgment providing for custody shall include a specific written parenting plan containing the 452.310.8 terms, which may be the plan the parties submitted, and in all cases the plan approved and ordered is in the court's discretion. No court may adopt a local rule, form, or practice requiring a standardized or default parenting plan, so the parents' own document is what the court works from.

• Best Interest Factors, Mo. Rev. Stat. 452.375.2(1) to (8)

  Eight open-ended factors govern custody, covering the parents' wishes and proposed plans, the child's need for meaningful relationships with both parents, interaction with parents and siblings, which parent is more likely to allow contact with the other, adjustment to home, school, and community, mental and physical health including any history of abuse, an intention to relocate the child's principal residence, and the unobstructed input of the child. If the court rejects the proposed arrangement, 452.375.6 requires a written finding detailing the specific relevant factors behind the rejection.

• Relocation Notice, Mo. Rev. Stat. 452.377

  A party relocating the child's principal residence for ninety days or more must give sixty days written notice by certified mail, return receipt requested, to any party with custody or visitation rights, with the six contents the section prescribes. There is no distance threshold, a motion to prevent the move must be filed within thirty days of receipt, the relocating party carries the burden of proving good faith and best interests, and an agreed revised schedule may be submitted with a signed affidavit and ordered without a hearing under 452.377.7.

• Domestic Violence Findings, Mo. Rev. Stat. 452.375.2(6) and 452.375.15

  Any history of abuse is a mandatory factor, and the court must enter written findings of fact and conclusions of law if it finds that awarding custody to an abusive parent is in the child's best interest. Custody and visitation must be ordered in a manner that best protects the child and any family or household member who is a victim of domestic violence from further harm.
