A parenting plan in Missouri is a written document required under Mo. Rev. Stat. § 452.310 in every divorce involving minor children. It must set a specific custody, visitation, and residential schedule, allocate decision-making, and address expenses. Parents must file a proposed plan within 30 days of service. Since August 2023, Missouri courts apply a rebuttable presumption of equal or approximately equal parenting time.

What Is a Parenting Plan in Missouri?
A parenting plan in Missouri is a court-required written document that sets out how divorced or separated parents will share custody, parenting time, decision-making, and child-related expenses. Under Mo. Rev. Stat. § 452.310, every dissolution involving children under 18 must include one, and each parent must file a proposed plan within 30 days of service.
The parenting plan is one of the most important documents in any Missouri custody agreement, because it becomes a binding court order once the judge approves it. The statute requires the plan to reflect arrangements the parent believes serve the best interests of the minor children. Missouri distinguishes between legal custody (decision-making authority) and physical custody (where the child lives), and your parenting plan must address both. A clear, detailed co-parenting schedule reduces future conflict and gives both parents an enforceable framework for raising their children across two households. Parents over 18 are excluded: under § 452.310, no parenting plan is required for any child over the age of eighteen for whom custody, visitation, or support is being established.
When Must You File a Parenting Plan in Missouri?
You must submit a proposed parenting plan within 30 days after service of process or the filing of an entry of appearance, whichever occurs first, under Mo. Rev. Stat. § 452.310. This 30-day deadline applies to both an original divorce petition and a motion to modify involving custody or visitation. Parents may file jointly or individually.
The timing of the parenting plan runs parallel to Missouri's other dissolution timelines. The court cannot enter a final judgment until at least 90 days of residency are established for one spouse and a mandatory 30-day waiting period has elapsed under Mo. Rev. Stat. § 452.305. If both parents submit identical or compatible plans, the court generally adopts the agreed plan. When the proposed parenting plans differ and the parents cannot resolve the differences, or when a parent fails to file a plan at all, the court will enter a temporary order containing a parenting plan after giving both parties an opportunity to be heard. That temporary order remains in effect until further order of the court and, importantly, creates no preference for the court when it decides final custody, child support, or visitation.
What Must a Missouri Parenting Plan Include?
A Missouri parenting plan must include three categories of provisions under Mo. Rev. Stat. § 452.310: (1) a specific written custody, visitation, and residential schedule; (2) a decision-making and dispute-resolution procedure; and (3) a plan for paying the child's expenses. Each category contains detailed, statutorily mandated elements that the court reviews before approval.
The residential schedule is the heart of the document. Your parenting time schedule must specify major holidays and which parent has the child each year, weekday and weekend routines, and how school vacations (winter, spring, summer) will be divided for school-age children. It must also set the times and places for exchanging the child and allocate transportation duties. The decision-making section must describe how parents will resolve disputes over interpreting the plan, and if a parent requests no shared decision-making, the plan must state the reasons. The financial section must address child care, educational, and extraordinary expenses as defined in the Supreme Court child support guidelines, the suggested amount of support each parent will pay, who maintains health insurance, and how uninsured medical, dental, vision, and psychological costs will be split.

How Does Missouri's Equal Parenting Time Presumption Work?
Since August 28, 2023, Missouri law applies a rebuttable presumption that an award of equal or approximately equal parenting time to each parent serves the best interests of the child, enacted through Senate Bill 35 and codified in Mo. Rev. Stat. § 452.375. Judges now start from a 50/50 parenting time position and adjust only when evidence shows it is not appropriate.
This presumption is one of the most significant changes in modern Missouri custody law, placing the state among the first in the nation to make equal parenting a statutory starting point. The presumption can be overcome only by a preponderance of the evidence under the statute's best-interest factors. A judge may order unequal parenting time in three situations: when the court finds a pattern of domestic violence; when the best-interest factors show equal time is not in the child's interest; or when the parents have reached their own agreement on all custody issues and ask the court to adopt it. Importantly, the law says "equal or approximately equal," not strictly 50/50. Missouri appellate courts have treated a schedule with about a one-day-per-week difference as still "approximately equal," giving parents flexibility to design a co-parenting schedule that fits work and school realities while staying within the presumption.
What Custody Factors Do Missouri Courts Consider?
Missouri courts weigh eight statutory best-interest factors under Mo. Rev. Stat. § 452.375 when reviewing a parenting plan or deciding contested custody. When parents do not agree on all issues, the judge must enter written findings of fact and conclusions of law explaining how these factors apply, making the analysis transparent and reviewable on appeal.
The factors guide the court even within the equal-parenting-time presumption, because the presumption supplies the starting point while the factors determine the final outcome. The eight factors balance the child's relationships, stability, and safety. A 2024 amendment (Senate Bill 1026) further emphasized considerations such as each parent's willingness and ability to cooperate, the distance between the parents' residences, any history of substance use, and the reasonable input of the child. The court also gives appropriate weight to the child's wishes based on age and maturity, but Missouri has no fixed age at which a child can choose which parent to live with. Where the court finds a pattern of domestic violence, a rebuttable presumption against awarding custody to the abusive parent applies, and the judge must make specific written findings showing the arrangement protects the child and any victim.
The Eight Statutory Custody Factors
| # | Factor (Mo. Rev. Stat. § 452.375) |
|---|---|
| 1 | The wishes of the parents and their proposed parenting plans |
| 2 | The child's need for a frequent, continuing, meaningful relationship with both parents, and each parent's ability and willingness to perform parental functions |
| 3 | The child's interaction with parents, siblings, and others who affect the child's best interests |
| 4 | Which parent is more likely to allow frequent, continuing, meaningful contact with the other parent |
| 5 | The child's adjustment to home, school, and community |
| 6 | The mental and physical health of all individuals, including any history of abuse |
| 7 | The intention of either parent to relocate the child's principal residence |
| 8 | The wishes of the child, given appropriate weight by age and maturity |
Joint Custody vs. Sole Custody in Missouri
Missouri recognizes four custody categories under Mo. Rev. Stat. § 452.375: joint legal custody, sole legal custody, joint physical custody, and sole physical custody, or any combination. Before awarding any arrangement, the court must consider joint physical and joint legal custody, and it cannot deny joint custody solely because one parent opposes it.
Understanding this distinction is essential when drafting your custody agreement. Legal custody concerns major decisions about education, health care, and religious upbringing; joint legal custody means both parents share decision-making authority. Physical custody concerns where the child lives day to day. Missouri case law clarifies that joint physical custody does not require an equal split of time; the test is whether each parent's custodial time is "significant." Courts may order joint custody even over one parent's objection, because agreement between parents is not a prerequisite. A 2024 appellate decision (Schiesswohl v. Spain) confirmed that giving one parent final decision-making authority on a single issue such as healthcare does not convert joint legal custody into sole legal custody. Your parenting plan should clearly state which custody type applies to legal and physical custody so the visitation schedule and decision-making rules are unambiguous.
How to Build a Co-Parenting Schedule That Works
A workable Missouri co-parenting schedule starts from the equal-parenting-time presumption and then adapts to the child's age, school calendar, and each parent's work obligations. Common frameworks include the 2-2-3 rotation, the week-on/week-off schedule, and the alternating-weekends-plus-midweek model, all of which can satisfy the "approximately equal" standard under Mo. Rev. Stat. § 452.375.
A strong parenting time schedule anticipates real life rather than just the ordinary week. For school-age children, the schedule must address how winter, spring, and summer breaks are divided, as required by Mo. Rev. Stat. § 452.310. Holiday provisions should alternate by year so neither parent loses every Thanksgiving or Christmas, and the plan should name specific exchange times and locations to prevent disputes. Including a right of first refusal (offering parenting time to the other parent before using a babysitter) and a clear communication method are common best practices. Because the parenting plan becomes an enforceable order, vague terms like "reasonable visitation" create problems; courts and parents both benefit from precise dates, times, and transportation responsibilities. Building in a dispute-resolution step, such as mediation before returning to court, satisfies the statute and saves both parents litigation costs.
Filing Fees and Court Costs in Missouri
The court filing fee for a Missouri divorce ranges from approximately $133 to $231, depending on the county and whether minor children are involved, as of June 2026. Cases with children typically cost more; for example, Jefferson County charges about $131 without children and $231 with children. Verify the exact amount with your local circuit clerk.
These fees cover the initial petition filing, not the cost of preparing or litigating a parenting plan. An uncontested dissolution handled without an attorney can be finalized in roughly 30 to 60 days for a total cost of $200 to $500 once filing fees and minor expenses are included. Low-income parents can avoid the filing fee by submitting a Motion and Affidavit in Support of Request to Proceed as a Poor Person, supported by documentation of income, expenses, and assets under oath. The Missouri Supreme Court provides free pro se dissolution forms at courts.mo.gov for uncontested cases, and self-represented filers must complete the free online Litigant Awareness Program before filing. Contested custody cases involving a guardian ad litem, custody evaluations, or mediation will cost substantially more. Filing fees change frequently and vary by county, so always confirm the current amount with the circuit clerk in the county where you file. (As of June 2026. Verify with your local clerk.)
Modifying a Parenting Plan in Missouri
A Missouri parenting plan can be modified after the final judgment, but the parent seeking change must show a substantial and continuing change in circumstances and that modification serves the child's best interests under Mo. Rev. Stat. § 452.410. The same 30-day deadline to file a proposed parenting plan under Mo. Rev. Stat. § 452.310 applies to modification motions.
Modification is intentionally harder than the initial order to protect stability for the child. Changes that may justify modifying a custody agreement include a parent's relocation, a significant change in a parent's work schedule, evidence the current arrangement harms the child, or a child's evolving needs as they grow older. Relocation receives special treatment: the relocating parent generally must provide advance written notice to the other parent before moving the child's principal residence. Notably, a request to give one parent final decision-making authority on a specific topic, such as healthcare, is not treated as a change from joint to sole legal custody, per the 2024 Schiesswohl v. Spain decision. Parents who agree on changes can submit a stipulated modified parenting plan for court approval, which is faster and cheaper than contested modification. Until the court approves a new order, the existing parenting plan remains fully enforceable, and parents who ignore it risk contempt proceedings.
