Modifying Custody Orders in Missouri

What changes in a family's life can lead to reconsidering a custody order?

The passage of time is a significant factor in reconsidering custody orders. As children grow, their needs and circumstances change, such as starting school or reaching driving age. This evolution in a child's life can prompt parents to reassess the suitability of their existing custody arrangements. Other factors include changes in parents' lives, such as new relationships or relocations, which may also necessitate revisiting the custody agreement.


Is a non-functional custody schedule enough to return to court?

To modify a custody order, the court requires evidence of a substantial change in circumstances. This could include changes in legal or physical custody classifications or adjustments to visitation times. While achieving the threshold of substantial change isn't particularly difficult, it does require documentation of significant life changes, like a new job impacting child support calculations or a parent's relocation.


Should parents who have amicably adjusted their custody schedule still formalize changes through the court?

Even if parents have amicably agreed to a new schedule, formalizing these changes in court can be wise. While the current arrangement may work, future conflicts could arise, especially if new partners become involved. By updating the custody order while relations are good, parents ensure the agreement reflects their current situation and protects against potential disputes.


What steps should a parent take if they believe a custody arrangement needs to change but the other parent disagrees?

If parents cannot agree on changes, the concerned parent must provide evidence of why a modification is necessary, prioritizing the child's best interests. This process involves presenting the situation to the court and demonstrating why the existing arrangement no longer works. The court will then evaluate the evidence and decide based on the child's welfare.


How should parents document changes to support a custody modification request?

Thorough documentation is crucial for supporting a request to modify custody. Keeping detailed records of expenses, visitation schedules, and any significant changes in circumstances can provide strong evidence. Utilizing apps or maintaining a physical record of receipts and calendars can help present a clear case in court.


How does a child's routine and relationship with each parent affect custody modification decisions?

Missouri law presumes joint legal and physical custody to be in the child's best interest. When considering modifications, the court evaluates the child's established routines and community ties, as well as each parent's relationship with the child. Any proposed changes must demonstrate how they better serve the child's needs and interests.


Can a parent's behavior influence the court's decision on custody changes?

Parental behavior can impact custody decisions, especially if one parent is not complying with the agreed plan. Violations related to financial responsibilities or parenting time can lead to contempt motions. While attorney's fees for such actions are rarely granted, demonstrating a pattern of non-compliance can influence the court's decision.


What is the typical timeframe for a custody modification decision?

The process for modifying a custody order can take several months. After filing, serving papers, and allowing both parties to respond, the court schedules hearings. Even with requests for emergency hearings, procedural delays mean that immediate changes are rare, emphasizing the importance of addressing issues promptly.


What should a parent do before seeking a custody order modification in court?

Before pursuing legal action, parents should consult with an attorney to understand the steps and gather necessary evidence. This may include enrolling the child in counseling to provide professional testimony or identifying witnesses like teachers or coaches. Building a strong, evidence-based case can help ensure the court considers the modification request seriously.
