Understanding Your Parental Rights in Missouri: What Every Parent Should Know
Missouri courts begin contested custody cases, assuming that each parent should have equal or near-equal time with their children. This presumption became law with the passage of Senate Bill 35 in August 2023 and continues to govern custody decisions in 2026. If you wish to have a different arrangement, you must prove it.
Equal Parenting Time Is a Presumption, Not a Promise
Under Section 452.375, a Missouri judge presumes that equal or approximately equal parenting time serves the child’s best interests. Rebuting it takes a preponderance of evidence measured against statutory best-interest factors, including each parent’s willingness to support the child’s relationship with the other parent, the child’s adjustment to home, school, and community, parents’ proposed arrangements, and history of domestic violence. The presumption steps aside when parents reach an agreement on custody, and most Missouri families do not litigate the issue at all.
Legal Custody and Physical Custody Are Different Rights
Physical custody covers where your child lives and who supervises them day to day. Legal custody covers decisions such as school enrollment, medical treatment, counseling and religious upbringing. You can have one without the other, but joint legal custody means that neither parent can make major decisions alone. This can catch people off guard months after a judgment is signed, so read that part of your parenting plan carefully before agreeing to it.
Both Parents Have a Right to School and Medical Records
Missouri gives both parents access to their child’s medical, dental and school records, unless a court denies that parent custody or visitation rights. You don’t need the other parent’s consent. Schools and clinics sometimes refuse anyway, but a certified copy of your judgement usually resolves it.
Moving With Your Child Triggers a Strict Notice Rule
Relocation under Section 452.377 refers to any change in a child’s primary residence that lasts 90 days or longer. This can include moving across town. The notice requirements for relocation are as follows:
- Written notice must be given at least 60 days prior to the move, by certified mail with return receipt requested.
- The intended new residence address, including the city or town, must be provided. If you don’t yet have an address, just provide the city.
- Information about the date of the move and the new home phone number must also be provided.
- A proposed revised schedule for custody and visitation must be included.
A text message or a phone call does not satisfy the statute. Missouri appellate courts have shown little patience for notices that miss a required element. If you are a parent who receives one of these notices, you have 30 days to file a motion objecting to the move. If that window closes and you lose the right to contest it, you may be forced to accept the change.
Unmarried Fathers Need Paternity Established First
Being named on the birth certificate is not a custody order. Until paternity is established and a court enters a parenting plan, an unmarried father in Missouri has no parental rights he can enforce. This is the most common reason why fathers lose contact with children during the first year following a separation.
