What Issues in a Divorce Decree Can Be Modified and What Cannot~ 3 min read
In Missouri, you can modify most parts of your divorce decree that involve children or support if circumstances change. Property division, however, is permanent once finalized. Mediation and the Collaborative Divorce process can help you make these changes more privately and flexibly than traditional court proceedings.
What Can Be Modified
Anything related to your children can be changed if it supports their best interests and if circumstances have significantly changed. This includes legal and physical custody, child support, parenting schedules, school and activity costs, and health insurance. Missouri courts allow modifications so that parenting plans remain practical and continue to work for your family as life evolves.
Maintenance, also known as spousal support, can also be modified. You may request an increase, decrease, or termination of maintenance depending on what has changed and the type of maintenance you were originally awarded. A parent’s health, retirement, job loss, or significant change in income can justify a new order. Maintenance may also end if the receiving spouse becomes self-supporting or begins living with a new partner.
What Cannot Be Modified
Once the division of property is complete, it cannot be changed. That part of your decree is permanent. Even if your financial circumstances shift later, the original property division remains in place.
The only exception occurs if a spouse hides assets during the divorce. In that case, you may be able to file a separate case in equity to recover the undisclosed property. However, these cases can be expensive and time-consuming, and success often depends on how your original judgment was written. This is why it is so important to have your divorce decree written accurately the first time and to disclose everything fully.
Using Mediation or Collaborative Divorce for Modifications
When you need to change parts of your decree, you can use Mediation or Collaborative Divorce instead of going straight to court. These methods allow you and your former spouse to talk through changes privately and create solutions that fit your family’s current needs.
Courts can only issue standard orders that follow strict legal guidelines. Through Mediation or Collaborative Divorce, you can agree to arrangements that are more flexible and creative. For example, you can agree to maintenance that ends on a certain date, a lump-sum payment, or shared responsibilities for future expenses in ways the court cannot order.
Mediation and Collaborative Divorce also help protect your privacy and allow you to reach agreements faster and with less conflict. These approaches often save time and money while keeping decision-making in your hands rather than leaving it up to a judge.
Moving Forward with Confidence
Life changes after divorce and Missouri law recognizes that your original orders may need to change with it. Whether you need to adjust child custody, support, or maintenance, working through Mediation or Collaborative Divorce can help you find solutions that fit your family’s circumstances today.
