Child Support Modifications in Michigan: When Can You Request a Change?

A Common Question After a Support Order Is Entered
Life changes. Income goes up or down. Parenting schedules shift. Children grow and their needs evolve. For many parents in Oakland and Wayne Counties, the question of whether a child support order can be changed is not hypothetical — it becomes very real when circumstances change after the order is in place.
The short answer is yes, child support orders in Michigan can be modified. But the process is not automatic, and not every change in circumstances qualifies. Understanding when a modification may be appropriate — and how to pursue one — is an important first step.
The Legal Standard: Significant Change in Circumstances
Michigan courts do not adjust child support simply because one parent requests it. A modification is allowed when there has been a significant change in circumstances since the existing order was entered — one that is substantial enough to affect the fairness or accuracy of the current amount.
Common grounds that Michigan courts may consider include:
A substantial increase or decrease in either parent's income — including job loss, promotion, career change, or retirement
A significant shift in the parenting schedule or custody arrangement, since the number of overnights directly affects the support calculation
A change in the child's healthcare coverage or a significant change in healthcare costs
New childcare expenses, or the elimination of existing ones
A change in the child's needs, such as new educational or medical requirements
Additional children in either household, though courts balance this against the existing support obligation
It is worth noting that changes must generally be substantial and lasting — not temporary or minor. A small pay raise or a short-term dip in income typically does not meet the threshold. Whether a particular change qualifies will depend on the specific facts involved.
The 2025 Michigan Child Support Formula Update
Michigan updated its child support formula in January 2025, introducing changes to how medical expenses and childcare costs are calculated. These updates may be relevant to parents with existing orders.
Specifically, the medical expense threshold dropped from $454 to $200 per child per year, meaning more out-of-pocket medical costs are now subject to sharing between parents. The 2025 revision also introduced changes to how childcare costs are handled in the formula.
For parents with orders entered before January 2025, these formula changes may — in some circumstances — provide grounds to request a review, particularly when combined with other changes in financial circumstances. Whether the update justifies a modification in any specific case will depend on the details.
Two Pathways for Requesting a Modification in Michigan
Friend of the Court Review
One of the most common and accessible ways to seek a modification is through the Friend of the Court office in the county where the case is filed. Either parent may request a FOC review of child support once every 36 months. If it has been more than 36 months since the last review, a parent can submit a written request and the FOC will recalculate support using the current Michigan Child Support Formula.
Some advantages of the FOC process include not having to file a formal motion, schedule a court hearing, or pay a motion filing fee. The FOC will request financial information from both parties, run the formula calculation, and recommend a change only if the difference between the current amount and the recalculated amount is at least 10 percent or $50 per month — whichever is greater.
Filing a Court Motion
If it has been less than 36 months since the last review, or if a parent needs a modification sooner than the FOC review process allows, either parent may file a motion directly with the court. This pathway can be faster when circumstances require immediate attention, but it generally involves more procedural steps, including completing a support modification forms packet, paying a filing fee, and potentially appearing in court.
One important consideration: Michigan courts generally cannot adjust support payments retroactively for periods before the modification request was filed. This makes timing critical. Parents who experience a significant change in circumstances should seek legal advice promptly rather than waiting.
Agreement Between Parents
If both parents agree to a modification, they may be able to submit a joint request to the court or, in some cases, work with the FOC to formalize the change. Any agreed modification must still comply with the Michigan Child Support Formula and receive court approval before it takes effect.
What Documentation Will Be Required
Regardless of the pathway used, parents seeking a modification will generally need to provide documentation supporting the claimed change in circumstances. This typically includes:
Recent pay stubs or a statement from an employer showing wages and deductions
Tax returns from recent years
Medical bills or documentation of new healthcare costs
Records of childcare expenses
Documentation of any change in custody or parenting time arrangements
Gathering this documentation carefully and presenting it clearly can significantly affect how a modification request is received by the FOC or the court.
Child Support and When It Ends in Michigan
Child support in Michigan generally continues until the child turns 18 or graduates from high school, whichever comes later. In cases involving a child with a disability or special circumstances, support may continue beyond those milestones.
If a parent's support obligation should have ended based on the child's age or graduation but payments are continuing, that parent may petition the court to terminate the obligation.
