FOC Michigan: What the Friend of the Court Does in Custody Cases

What the Friend of the Court Actually Is

The Friend of the Court is a county-level court agency that assists the Family Division of the Circuit Court in every Michigan domestic relations case involving minor children. Every one of Michigan's 83 counties has an FOC office, and it gets involved automatically when you file a divorce, custody, or paternity case — unless both parents formally opt out.

The FOC is not your advocate. It doesn't represent either parent. Its statutory role is to protect the interests of children and help the court make informed decisions about custody, parenting time, and child support.

The Four Main Functions

Custody and parenting time investigations. When parents can't agree on custody or a parenting schedule, the court directs the FOC to investigate. An FOC caseworker interviews both parents, the children (if old enough), and relevant third parties — teachers, doctors, therapists, extended family. The investigator visits both homes, reviews school records, and checks for any history of domestic violence or substance abuse. The result is a written report and recommendation that goes directly to the judge.

Here's the part most parents don't realize: if neither parent files a written objection within 21 days of receiving the FOC's recommendation, it may be submitted to the court for adoption; once the court approves and enters it, it becomes a binding court order. That 21-day window is not a formality.

Child support calculation and enforcement. The FOC calculates child support using the Michigan Child Support Formula, which factors in both parents' net incomes, health insurance costs, childcare expenses, and the exact number of annual overnights. The FOC collects support payments through income withholding (garnishment from the paying parent's employer) and enforces the order when payments fall behind — options range from driver's license suspension to tax refund interception to contempt of court proceedings.

Mediation and dispute resolution. Before contested issues go to a judge, the FOC may offer mediation services; ask the local FOC about applicable fees and procedures. A trained mediator helps parents negotiate custody arrangements, parenting time schedules, and child support disputes in a structured setting. Formal FOC mediation sessions are confidential — if you can't reach an agreement, the mediator tells the judge only that mediation was unsuccessful, without sharing details of what was discussed.

FOC mediation cannot begin until the case has been screened for domestic violence. If domestic abuse or other safety concerns are identified, the FOC may exclude the case from alternative dispute resolution; mediation may continue only with the protected party's written consent and added safety precautions.

Parenting time enforcement. When one parent violates the parenting time order — showing up late, canceling visits, refusing exchanges — the other parent can file a written complaint with the FOC. The complaint must be submitted within 56 days of the violation. The FOC then has 14 days to notify the offending parent and begin enforcement, which can include ordering make-up parenting time or scheduling a contempt hearing.

An important rule that trips up many parents: child support and parenting time are legally separate obligations. You cannot withhold parenting time because the other parent is behind on support, and you cannot stop paying support because you're being denied parenting time. The FOC enforces both independently.

The FOC Evaluation Process

An FOC custody evaluation typically follows this sequence:

1. Both parents complete detailed questionnaires about their living situation, work schedule, the child's daily routine, and their proposed custody arrangement
2. The investigator conducts individual interviews with each parent, usually at the FOC office
3. Home visits are scheduled — the investigator sees both residences and observes each parent interacting with the child
4. The investigator contacts collateral references (teachers, pediatricians, counselors)
5. Criminal background checks and CPS records are reviewed
6. The investigator writes a recommendation addressing each of the 12 Best Interest factors under MCL 722.23
7. Both parents receive the written recommendation and have 21 days to file a formal objection

If you object, the court schedules a de novo hearing — essentially a fresh review where the judge makes an independent determination without being bound by the FOC's recommendation. If you don't object, the court may adopt the recommendation without a de novo hearing.

Can You Opt Out of FOC Services?

Yes. Under Michigan law, parents can jointly agree to opt out of most FOC services by filing SCAO Form FOC 101 alongside their initial complaint. Opting out means the FOC won't calculate child support, mediate disputes, or enforce orders on your behalf.

Opting out makes sense for a narrow group of parents: those who are highly cooperative, financially stable, and confident they can manage their custody arrangement without court-backed enforcement. For everyone else, the FOC's enforcement authority — particularly around child support collection and parenting time violations — provides a safety net that's difficult to replicate on your own.

If you opt out and later realize you need FOC services, you can file a motion to opt back in.

Preparing for FOC Involvement

The FOC evaluation often determines the trajectory of your entire case. Walking in unprepared — without organized records of your involvement in your child's daily life, school, and medical care — puts you at a disadvantage against a parent who has documented everything.

The Michigan Child Custody & Parenting Plan Guide includes an FOC Investigation Prep Checklist and a Best-Interests Evidence Ledger structured around all 12 statutory factors, so you can organize your documentation before your evaluation appointment rather than scrambling to recall details on the spot.
