Understanding When to Modify a Parenting Plan

Missouri law allows for modifications to parenting plans under certain circumstances. These typically include significant changes in one or both parents' lives, such as a job relocation, a change in work schedule, or a child's changing needs.

It's essential to note that Missouri courts will not grant modifications based on trivial or frivolous reasons. The changes you're seeking must be substantial and in the best interest of your child.

Some common reasons for modifying a parenting plan in Missouri include:

  • Changes in work schedules that affect parenting time.
  • A child's changing needs or preferences as they grow older.
  • A parent's relocation for work or other reasons.
  • Concerns about the child's safety or well-being in the current parenting arrangement.

Missouri courts may deny modifications if they are sought solely to harass the other parent or if they would be detrimental to the child's well-being. For instance, frequent changes to the parenting plan can cause instability and uncertainty for the child.

It's also important to note that Missouri has a two-year waiting period for modifying child support orders, except in cases of fraud or a significant change in circumstances.

Once you've determined that a modification is necessary and in your child's best interest, you can begin the process of changing your parenting plan.

In Missouri, you typically need to file a motion with the court that originally issued your parenting plan. This motion should clearly state the reasons for the modification and how it will benefit your child.

Filing the Motion

Your motion should include detailed information about the changes you're seeking and why. It's a good idea to consult with a family law attorney to ensure your motion is complete and accurate.

You'll also need to serve the other parent with the motion. This can be done through certified mail or by hiring a process server. The other parent will have an opportunity to respond to your motion.

Attending the Hearing

After you've filed your motion, the court will schedule a hearing. Both parents are required to attend this hearing, along with their attorneys if they have one. At the hearing, you'll present your case for why the modification is necessary and in the child's best interest.

The other parent will have the opportunity to present their side as well. The judge will consider both arguments and make a decision based on the best interests of the child.

After the hearing, the judge will issue a new parenting plan if they decide a modification is warranted. It's crucial to follow this new plan, as failure to do so can result in contempt of court charges.

Remember, every family is unique, and so are their parenting plans. What's most important is that any changes you seek are in the best interest of your child. By understanding the process and working with a family law attorney, you can navigate the complexities of changing a parenting plan in Missouri.
