Missouri’s 2023 Shift to ‘Parenting Time’ Terminology

In August 2023, Missouri enacted significant amendments to its custody statutes that reflect a broader national trend toward child-centered language. While Missouri’s statutes under R.S.Mo. Section 452.375 still use the terms “custody” and “visitation” in certain provisions, the 2023 legislative changes placed greater emphasis on “parenting time” and “decision-making responsibility” as the functional concepts courts apply when structuring post-separation parenting arrangements.

The most consequential change was the creation of a rebuttable presumption that equal or approximately equal parenting time is in the child’s best interest. Prior to this amendment, Missouri courts had discretion to award any parenting time arrangement without a starting presumption. The new presumption shifts the baseline: unless one party presents sufficient evidence that equal time would not serve the child’s best interests, the court begins from the position that both parents should share roughly equal time with the child.

This terminology shift matters beyond semantics. By framing the arrangement as “parenting time” rather than “visitation,” the law reinforces the principle that both parents maintain an active parenting role after separation. The term “visitation” implied that one parent was a host and the other a guest; “parenting time” recognizes that both parents are exercising their parenting responsibilities during their respective periods. Courts and parenting plan forms in Missouri have increasingly adopted this updated language, and attorneys filing new cases should expect judges to apply the equal-time presumption as the default starting point.

Overview of Missouri Custody Law

Missouri custody law is governed primarily by R.S.Mo. Section 452.375, which establishes the framework for determining custody and visitation arrangements. Missouri directs courts to make all decisions based on the best interests of the child. The state does not favor one parent over the other based on gender.

Missouri law expresses a strong public policy in favor of frequent, continuing, and meaningful contact between the child and both parents after separation or divorce. Courts are directed to encourage parents to participate in custody decisions and to craft arrangements that promote the child’s stability and well-being.

Types of Custody in Missouri

Missouri recognizes both legal and physical custody, each of which may be awarded on a joint or sole basis:

  • Joint Legal Custody — Both parents share the right and responsibility to make major decisions about the child’s health, education, and welfare. Missouri law states that a court shall consider an award of joint legal custody, reflecting the state’s preference for shared decision-making.
  • Sole Legal Custody — One parent holds the exclusive authority to make major decisions for the child.
  • Joint Physical Custody — The child resides with each parent for significant periods, and both parents share in the day-to-day care of the child. This does not require an equal time split.
  • Sole Physical Custody — The child lives primarily with one parent, and the other parent has a visitation schedule.

For a broader explanation of custody types, see our guide on child custody laws explained.

The Parenting Plan Requirement

Missouri requires all custody cases to include a parenting plan under R.S.Mo. Section 452.310. Each parent must submit a proposed parenting plan to the court, and if the parents agree, they may submit a joint plan. The parenting plan must address:

  • The residential schedule, including regular parenting time, holidays, and vacations
  • Decision-making authority for education, health care, and religious training
  • A method for resolving future disputes
  • Transportation arrangements
  • Communication between the child and each parent during the other parent’s parenting time

If the parents cannot agree, the court reviews both proposed plans and fashions an order that serves the child’s best interests.

Best Interests Factors

Under R.S.Mo. Section 452.375.2, Missouri courts evaluate 8 factors when determining the best interests of the child:

  • 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, and the ability and willingness of parents to actively perform their functions as mother and father for the needs of the child
  • 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, meaningful, and continuing 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 wishes of the child, taking into consideration the child’s age and maturity

The court may also consider any other factor it deems relevant to the child’s best interests. For more on how courts evaluate these factors, see our guide on how child custody is determined.

Custody Presumptions

Since August 2023, Missouri has a rebuttable presumption under R.S.Mo. Section 452.375 that equal or approximately equal parenting time is in the best interest of the child. This presumption may be rebutted by a preponderance of the evidence showing that such an arrangement would not serve the child’s best interests. Missouri’s public policy also strongly favors frequent, continuing, and meaningful contact with both parents.

Notably, Missouri courts give significant weight to which parent is more likely to foster the child’s relationship with the other parent — a factor that can meaningfully influence the outcome.

Child’s Preference

Missouri does not set a specific age at which a child may express a custody preference. The court considers “the wishes of a child as to the child’s custodian, taking into consideration the age and maturity of the child.” In practice, older and more mature children receive greater weight, but the court retains full discretion and evaluates whether the child’s preference reflects independent reasoning. The judge may interview the child in chambers or receive the child’s views through a guardian ad litem.

Relocation Rules

Missouri has a detailed relocation statute under R.S.Mo. Section 452.377. A parent who intends to relocate with the child must provide written notice to the other parent at least 60 days before the proposed move. The notice must be sent by certified mail and must include the intended new address, the reason for the move, and a proposed revised custody schedule.

The non-relocating parent may file an objection within 30 days of receiving notice. If an objection is filed, the court holds a hearing and considers the reasons for the move, the impact on the child, the feasibility of a modified visitation schedule, and whether the move is made in good faith. The relocating parent bears the burden of proving the relocation is made in good faith and is in the child’s best interest.

Mediation

Missouri does not mandate mediation statewide for all custody cases. However, many Missouri courts encourage or order mediation before proceeding to trial in contested custody disputes. Some circuits have local rules requiring mediation as a standard step. Mediation provides parents with an opportunity to negotiate a parenting plan with the assistance of a neutral third party, and agreements reached in mediation can be submitted to the court for approval.

Modification of Custody Orders

To modify an existing custody order in Missouri, the parent seeking the change must file a motion and demonstrate that there has been a substantial and continuing change in circumstances since the prior order and that the modification serves the child’s best interests. Under R.S.Mo. Section 452.410, the court will not modify a custody decree within two years of the original order unless there is evidence that the child’s present environment endangers the child’s physical, mental, moral, or emotional health.

After the two-year period, the court applies the general change-in-circumstances standard and re-evaluates the arrangement under the best interest factors.

Missouri custody law includes mandatory parenting plan requirements, a multi-factor best interest analysis, and specific relocation notice procedures. The 2023 presumption of equal parenting time and the emphasis on which parent is more likely to foster the child’s relationship with the other parent are particularly significant features that can shape outcomes. If you are navigating a contested custody case, a relocation dispute, or a modification, consider scheduling a free consultation to discuss your options with a qualified professional.

Frequently Asked Questions

How many best interest factors does Missouri evaluate?

Under R.S.Mo. Section 452.375.2, Missouri courts evaluate 8 factors: the parents’ wishes, the child’s needs and relationship with each parent, the child’s adjustment to home, school, and community, the mental and physical health of all parties, each parent’s willingness to facilitate the other parent’s relationship, and the child’s interaction with siblings and significant persons.

What are Missouri’s relocation rules?

Under R.S.Mo. Section 452.377, a parent must provide written notice by certified mail at least 60 days before a proposed relocation. The notice must include the intended new address, reason for the move, and a proposed revised custody schedule. The non-relocating parent may object and request a hearing.

At what age can a child express a custody preference in Missouri?

Missouri does not set a specific age. The court considers “the wishes of a child as to the child’s custodian, taking into consideration the age and maturity of the child.” Older, more mature children receive greater weight, but the court retains full discretion. The judge may interview the child or receive views through a guardian ad litem.

How does the 2023 equal parenting time presumption work in practice?

The rebuttable presumption under the 2023 amendments to R.S.Mo. Section 452.375 means the court starts from the position that equal or approximately equal parenting time serves the child’s best interest. Either parent can rebut this presumption by presenting evidence — such as a history of domestic violence, substance abuse, geographic distance, or other factors — showing that equal time would not be in the child’s best interest. The presumption shifts the default starting point but does not guarantee a 50/50 outcome.

Can a custody order be modified within the first two years in Missouri?

Under R.S.Mo. Section 452.410, the court generally will not modify a custody decree within two years of the original order. The exception is when there is evidence that the child’s present environment endangers the child’s physical, mental, moral, or emotional health. After two years, the standard change-in-circumstances test applies.
