Can Child Support Be Modified Without Going to Court?~ 3 min read

Child support can be modified in Missouri without a courtroom battle if you and the other parent are able to reach an agreement. Through Mediation, Collaborative Divorce, or informal discussions, you can create a new support arrangement and submit it to the court for approval, saving time, stress, and conflict.

The short answer is yes, but not in the way you might think. A judge still must approve any changes to child support.  If you and the other parent reach an agreement, you can put everything in writing, file the proper documents, and have a judge sign off. In many cases, this is quick and straightforward. You are not standing before a judge arguing your case. Instead, it feels more like filing paperwork than going to court.

You have several options if you want to avoid a drawn-out legal dispute:

  • Mediation
    Mediation gives you and the other parent a structured setting to talk through the details. A neutral third party helps guide the conversation so you can reach common ground. You can discuss income, expenses, and how support should be adjusted.
  • Collaborative Divorce
    Collaborative Divorce allows both of you to work with attorneys in a cooperative setting. The goal is to find a solution that works for everyone without litigation. This process keeps communication more productive and focused on the child’s needs.
  • Informal Agreement
    In some cases, you may be able to sit down together and work things out on your own. If you agree to the new terms, an attorney will draft the paperwork so it can be submitted to the court for approval.

Once your agreement is submitted, a judge will review it. In most cases, if you both agree and the terms appear reasonable, the judge will sign off without issue.

There are a few situations where a judge might take a closer look. For example, if one parent is giving up child support entirely and the child is still young, the court may want an explanation,  because child support is considered a right that belongs to the child, not to the parent.

Several common situations can lead you to revisit child support:

  • A significant change in income for either parent
  • Job loss or illness
  • Increased needs for the child
  • Outdated support orders that no longer reflect current finances
  • Changes in state guidelines or cost of living

Even if support guidelines have changed over time, you usually need an additional reason, such as a change in income, to justify a modification.

Resolving child support questions through agreement can save time, reduce stress, and give you more control over the outcome. Instead of leaving decisions in the judge’s hands, you and the other parent can create a plan that fits your real-life situation.

1. Can we change child support without hiring attorneys?
Yes, you can reach an agreement on your own. However, it is still wise to have an attorney prepare or review the paperwork before submitting it to the court.

2. How long does it take for a judge to approve a modification?
If both parties agree and the paperwork is complete; approval is sometimes quick. Timing will vary depending on the court, but many cases move through without delay.

3. What happens if we cannot agree on a new amount?
If you cannot reach an agreement, you will need to file a motion and have a judge decide. In that case, a court appearance is more likely.

    The current pandemic has made it difficult for some parents to spend time with their children. While the Courts have made it clear that they expect existing custody orders to be followed during the ongoing COVID-19 pandemic and Stay at Home Orders, issues may still arise that make it difficult for parents to exchange children during this time. For example, one parent may have been exposed and be required to self-quarantine while the children were with the other parent, and the children may not be able to immediately come over; children may be required to quarantine with a particular parent if they were exposed while with that parent; or the parties may simply be unable to travel at this time. This could result in one…

  • Child Temporary Power of Attorney

    When children are injured or become ill, their parents or legal guardians have the right to make decisions regarding their medical care. In some cases, permission from a parent or legal guardian is necessary before a doctor can pursue certain treatment options. This situation can become complicated when the child is not currently in the care of a parent or guardian. If the child’s caretaker is not their legal guardian, they may lack the right to make these decisions, which could lead to a delay in treatment that could prove harmful to the child. A temporary delegation to an attorney in fact is a legal document that temporarily grants someone the power to make decisions regarding a child’s healthcare. These can be as short as…
