Relocating With a Child: A Survival Guide to Missouri's Strict Custody Relocation Statutes
Aug. 10, 2026
Moving to a new home can become considerably more complicated when you share custody or visitation rights with another parent. A new job, family responsibilities, housing needs, or other changes may make relocation necessary, but moving your child's principal residence can affect an existing custody arrangement.
Missouri law establishes specific notice requirements and deadlines for relocation. Failing to follow them can affect your ability to relocate and may have consequences for your existing custody arrangement.
As a St. Louis custody lawyer, I help parents understand Missouri's relocation requirements, whether they are proposing a move or objecting to one. From The Hardin Law Firm LLC in St. Louis, Missouri, I assist parents with child custody matters and help them understand the legal steps involved when relocation affects an existing parenting arrangement. Contact my law firm today to discuss your situation.
Missouri Relocation Laws and What They Require
Missouri Revised Statute § 452.377 defines relocation as a change in a child's principal residence for 90 days or more, excluding a temporary absence. Contrary to a common misconception, the statute is not limited to moves across state lines or into another county. A move within the same general area may qualify if it changes the child's principal residence for the required period.
The statute requires notice of a proposed relocation of the child's residence or the residence of a party entitled to custody or visitation. Unless a court finds exigent circumstances, written notice generally must be provided at least 60 days before the proposed relocation.
Failure to provide the required notice can have significant consequences. A court may consider the failure when deciding whether custody or visitation should be modified, order the child's return if relocation occurred without notice, or require the relocating party to pay reasonable expenses and attorney's fees incurred by the objecting party. A violation may also be treated as a change in circumstances that permits modification of a prior custody decree.
Mandatory Details for the Proposed Relocation Notice
Missouri law generally requires the relocation notice to be sent in writing by certified mail, return receipt requested, to parties with custody or visitation rights. The notice must contain specific information.
Intended residence details: Include the specific new address and mailing address, if known. If the address is not yet known, provide the city. Include the new residence's home telephone number if known.
Proposed moving date: State the date of the intended move or relocation.
Reasons for moving: Provide a brief statement explaining the specific reasons for the proposed relocation of the child, when applicable.
Revised parenting schedule: Include a proposed revised custody or visitation schedule when applicable.
Objection rights statement: Inform the other parent of the right to file a motion seeking to prevent relocation, along with the required affidavit, within 30 days after receiving notice.
Missouri law also recognizes exceptions when disclosure of identifying information could create an unreasonable health or safety risk and for participants in the state's address confidentiality program.
Because mistakes in notice can create unnecessary problems, it is worth having a child custody lawyer review the proposed relocation and applicable requirements before you move.
Legal Responses and Court Proceedings
Once proper notice is received, a parent who wants to prevent the child's relocation generally has 30 days to file a motion seeking an order prohibiting the move. The motion must include an affidavit setting out the specific good-faith factual basis for the objection.
If a timely motion is filed, the person seeking relocation generally has 14 days to respond unless the court extends the deadline for good cause. The response must include a counter-affidavit supporting the relocation and a proposed revised parenting plan.
If no parent files a motion to prevent relocation within 30 days after receiving the required notice, § 452.377 provides that the child's residence may be relocated 60 days after notice was provided.
Parents can also agree on a revised custody and visitation schedule. If they reach an agreement that includes a parenting plan, Missouri law allows them to submit the agreement and the required signed affidavit to the court, which may order the revised plan without a hearing.
If you receive relocation notice and object to the proposed move, acting promptly matters because the statutory deadline is short. I can help you evaluate the proposed relocation, prepare the required filings, and protect your rights under the existing family law orders.
What Must a Parent Prove to Relocate a Child?
When a proposed relocation is contested, Missouri law places the burden on the party seeking to relocate. That parent must prove both that the proposed relocation is made in good faith and that it is in the child's best interest.
There is no single piece of evidence that establishes whether relocation satisfies those requirements. Relocation disputes are fact-specific, and the circumstances affecting the child and existing parenting arrangement can matter.
Depending on your case, relevant evidence may involve the reasons for the move, the child's current circumstances, the proposed parenting plan, and how meaningful contact with the nonrelocating party can continue.
If relocation is permitted, Missouri law directs the court to provide for contact with the nonrelocating party sufficient to maintain frequent, continuing, and meaningful contact unless the child's best interests require otherwise. The court must also address transportation costs and adjust child support when appropriate in light of those costs.
Careful preparation is therefore important whether you are seeking to relocate or challenging a proposed move. I can help you identify the evidence relevant to your position and present your case under Missouri's criminal defense and family law procedures.
