Child support orders are not permanent. Changes in income, parenting schedules, or a child’s needs may make a current support order unfair or outdated. Either parent can ask the court to modify the child support order when there is a substantial change in circumstances. A St. Louis child support lawyer can help you modify an existing order if you need to do so.
In Missouri, this process is handled in the Family Court Division of the Circuit Court of St. Louis County for St. Louis-area families, or through the Missouri Department of Social Services (DSS) in some cases.

When You Can Modify Child Support in Missouri
Missouri Revised Statute § 452.370 allows a parent to seek a child support modification when there has been a “substantial and continuing change in circumstances”. The current situation has changed to the point where the previously established support order becomes unreasonable or unfair. Some common changes include:
- A major change in one parent’s income
- One parent losing their job
- One parent experiencing disability
- Child custody changes
- Remarriage
- New dependents
- A significant change in the child’s needs, such as sudden medical or educational expenses
Not every life event warrants a change. The shift needs to continue rather than be temporary. The court might refuse to change the order, for instance, if a parent loses their job but anticipates finding another one in a few weeks. However, a significant medical condition, a prolonged period of unemployment, or a permanent change in custody might warrant a modification.
How to File for a Modification in St. Louis
Missouri sees its fair share of child support cases each year. The Missouri Department of Social Services saw the following caseloads in 2025:
- 278,221 child support cases in September
- 278,953 child support cases in August
- 279,359 child support cases in July
Most parents go through the St. Louis County Family Court in Clayton, MO. The process begins when you or your attorney file a Motion to Modify Child Support with the circuit court where the original order was issued. The other parent will be served and will have an opportunity to respond.
Once both parents submit financial statements and evidence, the court may set a hearing. If the parents agree on the new terms, the case can proceed quickly. However, if the parents disagree, the judge will evaluate the financial evidence and issue a new order in accordance with Missouri’s child support guidelines.
If the original order was issued or enforced by the Family Support Division (FSD), it may be possible to request a review directly through DSS. The agency will conduct an Administrative Review to determine whether the current order continues to meet state guidelines. The administrative review process can be quicker and less formal than the courts, but it is only available for qualifying cases.

They can speak for you at your hearings, work with the other parent to negotiate a fair adjustment, and ensure you are receiving the proper amount of support based on your current circumstances.

FAQs
Q: When Can Child Support Be Modified in Missouri?
A: Child support modifications are possible in Missouri if there has been a substantial and continuing change in circumstances. This can include a significant change in income, a job loss, a medical condition, or changes in parenting time. Missouri law typically requires a significant discrepancy between the current order and the recalculated amount to approve the modification.
Q: What Documents Do I Need to Modify My Current Child Support Order?
A: Documents you need to modify your current child support order include recent pay stubs, tax returns, evidence of health insurance premiums or costs, childcare expenses, and any proof of financial changes or custody arrangements. The court or Family Support Division will use these documents to determine the new support amount. Accurate and up-to-date records will assist in a fair and expedient decision on your modification.
Q: What Happens if My Co-Parent Does Not Agree to the Modification?
A: If one parent objects to the modification, a court hearing will be set. Each parent will have the opportunity to present financial records and testimony. The judge will rule in accordance with the Missouri child support guidelines and the child’s best interests. It is advisable to have legal counsel to ensure your position is accurately presented and properly documented.
Q: Can Child Support Be Reduced if I Lose My Job?
A: Yes, but it’s not automatic. You must file a formal motion to modify your support order as soon as possible if you lose your job. The court will review your financial situation and decide if the change is significant and continuing. You must continue paying the original amount until the modification gets approved.
