Michigan Child Support Guidelines

Michigan's current guideline baseline runs through the 2025 formula materials, the official public MiChildSupport calculator, and the statutory rule that courts must use the formula unless they explain a deviation in writing.

Why old Michigan summaries go stale

In Michigan, the live formula manual, the live supplement, and the current public MiChildSupport workflow control the working baseline. Older summaries often miss manual updates or treat private estimates like official order guidance.

Guideline checkpoints that matter most

Formula-first workflow: Michigan still routes support math through the published formula materials and the official public calculator path.
Public calculation is not the final order: MDHHS currently states that the MiChildSupport result is not itself a recommendation or court order.
Written deviation still matters: If the formula amount is not used, Michigan still expects a written explanation for the different amount.
Review timing matters: MDHHS currently states that parents may ask for a Friend of the Court review every 36 months, even though motion practice can happen sooner.
Current materials matter more than old summaries: The 2025 manual and supplement are the safer baseline than recycled historical notes.
