Understanding Missouri's Parenting Plan Laws

Missouri law requires divorcing parents with minor children to submit a parenting plan to the court. This plan outlines the legal and physical custody arrangements, decision-making responsibilities, and parenting time schedule. It's essential to familiarize yourself with these laws to understand what can and cannot be changed.

Missouri Statutes § 452.375 outlines the required elements of a parenting plan. These include a proposed schedule for the child's time with each parent, a decision-making plan for significant decisions regarding the child, and any other provisions the parents agree to that are in the best interests of the child.

A parenting plan can be modified if there has been a significant, unforeseen change in circumstances that warrants a change. Some examples include a change in work schedules, a move by one parent, or a change in the child's needs or preferences. However, a modification cannot be based on a temporary change or a change that is not in the child's best interests.

Missouri courts will consider the following factors when deciding whether to modify a parenting plan: the wishes of the child's parents, the needs of the child for a frequent, continuing, and meaningful relationship with both parents, the interaction and interrelationship of the child with parents, siblings, and other family members, and any history of domestic violence or child abuse.

If you and your co-parent agree to the changes, you can submit a modified parenting plan to the court. Both parents must sign the modified plan, and it must be approved by the court. To modify the plan, follow these steps:

  • Draft a modified parenting plan that reflects the agreed-upon changes.
  • Ensure the modified plan complies with Missouri's parenting plan requirements.
  • Both parents must sign the modified plan.
  • File the modified plan with the court that issued the original parenting plan.
  • Pay the required filing fee. If you cannot afford the fee, you can request a waiver.
  • The court will review the modified plan to ensure it is in the best interests of the child. If approved, the modified plan will become a court order.

2. **Serve the Motion:** Serve the motion on your co-parent. This can be done by a process server, the sheriff's department, or certified mail with return receipt requested.

3. **File a Response:** Your co-parent has 30 days to file a response to the motion. If they do not respond, the court may grant the modification without a hearing.

4. **Attend the Hearing:** If your co-parent responds to the motion, a hearing will be scheduled. Both parents will have the opportunity to present evidence and argue their case. The court will then decide whether to grant the modification based on the best interests of the child.

What if My Co-Parent Refuses to Cooperate?

If your co-parent refuses to cooperate with the modification process, you can still proceed with the court process. However, it's crucial to document all attempts to communicate with your co-parent and any instances of non-cooperation. This can be used as evidence in court.

In some cases, the court may order mediation to help resolve the dispute. Mediation is a process where a neutral third-party facilitates negotiations between the parents. If mediation is successful, the mediator will draft a parenting plan that reflects the agreed-upon changes.

Modifying a parenting plan in Missouri can be a complex process, but with the right understanding of the laws and procedures, it can be done effectively. If you have any questions or need further assistance, consider consulting with a family law attorney. They can provide guidance tailored to your specific situation and help ensure that the best interests of your child are met.
