Child Support in Michigan: How to Apply, Change, and Enforce Support

Where to start

Start with your situation, not with a random form. Michigan has different paths depending on whether you already have a court case, whether parentage has been established, whether you receive public assistance, and whether safety is a concern.

If a child or parent lives in another state, do not assume you need to open a second case. Ask the Michigan Office of Child Support or your existing FOC which state and court should handle the order.

How Michigan child support works

Michigan’s child support system has several parts. The state

parent handbook

explains that the Office of Child Support, Prosecuting Attorney, Friend of the Court, courts, and MiSDU may all have a role. The court signs the order. After that, the Friend of the Court and MiSDU help track and process support.

The

program overview

from Michigan Courts explains the basic path: apply, the Office of Child Support begins the case, the Prosecuting Attorney may prepare the order, the circuit court enters the order, the Friend of the Court tracks and enforces the order, and MiSDU handles payments.

The child support program can help locate a parent, establish parentage, get a support order, enforce an order, and handle some cases where a parent lives outside Michigan. It cannot be your lawyer. It also does not solve every custody or parenting time problem.

The Friend of the Court can help with some court forms and court-order issues, but it cannot give legal advice or change an order without court action. For broader support, ASMOM also has a

child support guide

and a
Michigan help guide
.

These offices have different jobs:

OCS helps start services; county prosecutors may help establish parentage and orders; the circuit court makes enforceable orders; county FOC offices handle most payment tracking, review, and enforcement; MiSDU moves and records payments. Your case may follow a different path if an order already exists or another state is involved.

Child support when you get public benefits

Receiving benefits does

not

mean the same child support rule applies to every program. Michigan’s

public assistance guidance

explains that people getting certain cash assistance or Medicaid may be asked to cooperate with the child support office. Watch for letters from MDHHS and respond by the date on the notice, or ask promptly about a safety-based good cause claim.

Michigan’s

child support cooperation policy

says that

Food Assistance Program (FAP/SNAP) and Child Development and Care (CDC)

recipients are

not required to cooperate with child support as a condition of those benefits

. They can still request child support services if they wish. If you also receive cash assistance or Medicaid, that program may still have a cooperation rule; a sanction for that program does not automatically mean your SNAP or CDC benefit should be cut. If a letter appears to say otherwise, ask MDHHS to check which benefit and rule applies to your case.

When a family gets cash assistance through the Family Independence Program (FIP), some child support rights are assigned to the state under program rules. This may affect how payments are distributed. Ask the worker how support, cash assistance, and any payments owed to you interact. Do not assume every payment will come straight to you or that the full amount will go to the state.

For help with confusing benefit notices, Michigan’s

child support forms page

has response and protection forms. Keep copies of forms you send and the date they were received.

How Michigan child support is calculated

Michigan courts use the Michigan Child Support Formula when setting or changing most child support orders. The official

formula page

lists current and past manuals and supplements. The

2025 Michigan Child Support Formula

took effect January 1, 2025, and remains the published manual used for this guide. Check the state page for any later replacement before a court filing.

Support is not a flat rate for every child. The formula uses each parent’s income under its rules, the number of children, parenting-time overnights, health coverage, medical costs, and qualifying child care costs. It also has rules for very low income, other children, and special cases.

The official
2025 formula manual
says courts must order support based on the formula unless state law allows a different result. This means the facts in your case matter. Self-employment, overtime, disability benefits, public benefits, health insurance, child care subsidy, and parenting time can all affect the number.

Child care support can be included when child care is tied to work, job search, training, or education. Medical support can also be included. The exact order controls what each parent must pay and how payment must be made.

A judge may order a different amount only when the legal rules for a departure from the formula are met and the court explains the reasons. The original

2025 formula manual

gives the details. Keep pay stubs, work costs, parenting schedules, and proof of actual child care and health costs for any review.

If you have lived in another state, rules may differ. ASMOM’s comparison of

state child support laws

explains why one state’s methods should not be used to guess a Michigan court order.

The MiChildSupport calculator may give an estimate, but the court order controls. Do not use another parent’s result or an online guess to decide what is legally owed.

How to apply for child support services

You can apply online using

Michigan’s start-a-case guide

and MiChildSupport. You can also print the

DHS-1201 application

and mail the signed form to

Michigan Department of Health and Human Services, Office of Child Support, PO Box 30744, Lansing, MI 48909

, as the form directs. If you are not sure where to send a form, confirm with OCS at

866-540-0008

.

If you receive or once received cash or medical assistance, Michigan may have opened a child support case for your family. If you did not receive an OCS letter within three months after your assistance case opened, or you are unsure whether a case exists, call

866-540-0008

before applying again. Food or child care assistance alone does not have the same mandatory-cooperation rule.

Parents, caretakers, and some guardians may be able to ask for child support services. You do not have to be married to the other parent. You do not need to know every detail about the other parent, but accurate information can help the office find the parent and move the case forward.

If parentage is not legally established, OCS and the county prosecutor may help with that step before a support order can be made. A court may require genetic testing in a disputed case. Do not sign a parentage form you do not understand; ask for legal help if needed. You can apply even if you do not know every fact about the other parent.

After applying:

Save your confirmation, a copy of the form, and the date you sent it. Watch for letters, requests for proof, and court papers. Ask which office will contact you next and how to check status. There is no guaranteed time for locating a parent, setting an order, or receiving the first payment.

Payments and missed payments

Michigan sends child support payments through MiSDU in most cases. The state

payment options

page says payments go to the centralized Michigan State Disbursement Unit, which processes the money and sends it to the parent or caregiver who should receive it, or to the state if public assistance reimbursement applies.

If you are the parent who pays support, pay the way your order requires. Paying cash directly can create problems if it is not recorded correctly. If you are the parent who receives support, keep your address, direct deposit, or debit card information updated so payments do not get delayed.

MiSDU’s

receiving payments

page says support recipients can track payments through MiChildSupport. If payments are late, contact the Friend of the Court in the county that has the order.

Michigan’s

enforcement page

lists tools such as income withholding, liens, license actions, tax refund intercepts, and other steps. These tools do not all happen at once, and they depend on the facts of the case.

Use the

official case information guide

to check what is owed, what was received, and which county FOC handles the order. The state’s

contact-by-issue page

also lists the 24-hour FOC/MiSDU phone system at

877-543-2660

. Keep a record of payment dates and any employer information you know.

If payments are missing, first ask whether the payment was received, held, sent, or credited to a different period. Request a payment history and ask the FOC what it needs to review enforcement. Income withholding, tax offsets, liens, and license actions have legal rules; the office may not be able to use every tool in your case.

Do not assume an unpaid balance will disappear if a parent changes jobs, moves away, or stops working. If a payment was made directly, save proof and ask the FOC whether it can be credited under your order. Never ignore an income withholding notice or a court payment demand.

Changing a child support order

A child support order does not change by itself. If income drops, work hours change, a child moves, health insurance changes, or child care costs change, the old order stays in place until the court changes it. Verbal agreements between parents can create serious problems.

The state

order-change guide

says that when either parent receives public assistance, the Friend of the Court automatically reviews the support amount every

36 months

. Without public assistance, a parent can still request a review every 36 months. A county FOC may consider certain earlier review requests, but it is not required to review every change in income. Ask what process applies in your county.

If the last review was less than 36 months ago, you may still file a

motion with the circuit court

to seek a change. A fee may apply, but some people can ask for a fee waiver. Use Michigan Courts’

Friend of the Court forms

and check county filing rules. Michigan Legal Help’s

change-order instructions

explain the main choices.

Ask for help early if you lost work, your pay fell, child care or medical costs changed, you became disabled, started receiving benefits, were incarcerated, or could not meet the old order.

A change usually is not backdated to the day your income fell.

Waiting may cause past-due support to build. If a support payer is unable to earn income for a long time or is incarcerated, special Michigan rules may apply; contact the FOC rather than assuming support stops automatically.

For a review, the state may ask for four recent pay stubs, recent income tax returns, business records if self-employed, and proof of child care costs. Ask for the questionnaire and submit complete proof by its due date. A change in parenting time or where a child lives may also matter, but the court must handle the order.

If a court notice is wrong or you disagree

Read the paper first.

It should say what decision was made, where to respond, and the deadline. Save the envelope and note when you received it. A Friend of the Court recommendation, a signed order, and a notice about benefits are not the same kind of document.

Under Michigan’s current court rules, many referee recommendations allow

21 days after service

to file a written objection. Different notices or actions may have other rules. Do not assume you have 21 days for every notice. Follow the deadline written on your own papers and ask the court clerk or legal aid how to file and serve an objection.

If you missed a deadline, got a notice at the wrong address, or are unsure what a form means, call your county court or use

Michigan Legal Help’s FOC overview

promptly. A lawyer may be needed if a hearing or appeal could affect custody, safety, or a large unpaid balance. This guide is information, not legal advice.

Safety concerns and good cause

Child support can be complicated when there has been abuse, stalking, threats, or control by the other parent. A family receiving certain public assistance may be asked to cooperate with support services, but there are

good cause and family-violence protections

. Ask the MDHHS worker about a good cause claim before you share information that may expose your address, work, school, or child care location.

Use a safer phone or device if your calls or browsing may be watched. A domestic violence advocate can help you think through safer contact, court papers, address issues, and support choices. ASMOM’s

domestic violence guide

has national safety-aware starting points, and ASMOM’s

legal help guide

covers legal and family safety basics.

Michigan has a

Request to Protect Information (MDHHS-5728)

on its official forms page. Tell OCS, the FOC, and the court about privacy and safety concerns. A good cause claim and an information-protection request serve different purposes and do not guarantee every document will be hidden. Ask a trained advocate how each step may affect your case.

You do not have to contact the other parent to ask the state how its process works. If anyone can read your messages or see your device, seek advice from a safer phone or trusted support service when possible.

Documents checklist

You may not need every item, but gather what you can before you apply, call, or file a motion. ASMOM’s
documents checklist
can help you build one folder for benefits, court, school, housing, and child support papers.

For a court review or a disputed payment, also bring the current court order, county/case number, notices, payment history, and proof of when you sent forms. If you are self-employed, bring tax schedules and business records as requested. Do not share private records with anyone who cannot show that they are the court or an authorized agency.
