Third Party Custody in Michigan Under MCL 722.26c

What Third-Party Custody Means in Michigan

Third-party custody under the Child Custody Act (MCL 722.26c) gives a non-parent — typically a grandparent, aunt, uncle, or other relative — legal custody of a child through the circuit court's family division. Unlike probate court guardianship, a third-party custody order resolves actual custody rights between the parties and can include provisions for parenting time, child support, and long-term placement.

The upside: third-party custody is permanent until the child turns 18 or the court modifies the order. There's no six-month cap like temporary guardianship and no placement plan that the parent can satisfy to automatically trigger termination.

The downside: the standing requirements are among the strictest in Michigan family law.

Who Has Standing to File

Michigan does not recognize "de facto custodian" status. Living with a child for years, paying for their food and clothing, and enrolling them in school does not create a legal right to file for custody. Under MCL 722.26c(1), a third person can file an original custody complaint in circuit court only if one of two narrow conditions is met:

Condition 1 — Adoption placement. The child was placed with you for adoption under Michigan adoption laws, the placement order is still active, and the child has lived with you for at least six months after placement.

Condition 2 — Deceased or missing custodial parent. All four of these must be true:

• The biological parents were never married
• The custodial parent has died or is missing
• The noncustodial parent has not been granted legal custody by any court order
• You are related to the child within the fifth degree by blood, marriage, or adoption

If neither condition applies to your situation, you cannot file for third-party custody directly. The alternative route: first obtain appointment as a guardian through probate court (under MCL 700.5204), which then gives you independent standing to bring a custody action under MCL 722.26b.

The Parental Presumption

Even if you clear the standing hurdle, third-party custody cases carry a powerful legal presumption. Under MCL 722.25(1), when custody is disputed between a natural parent and a third person, the court must presume that the child's best interests are served by awarding custody to the parent.

You overcome this presumption only by presenting clear and convincing evidence — a higher standard than the typical preponderance of the evidence — that placing the child with the parent would not serve the child's best interests. The U.S. Supreme Court reinforced this in Troxel v. Granville (2000), holding that fit parents have a fundamental constitutional right to direct their children's care and upbringing.

In practice, this means you need strong evidence: documented neglect or abuse, a parent's ongoing incapacity, or a pattern of behavior that would put the child at risk. A disagreement over parenting style or the belief that the child would be "better off" with you is not enough.

How It Differs From Probate Guardianship

The two paths serve different functions and run in different courts:

Probate guardianship (MCL 700.5204/5205) focuses on appointing someone to manage the child's daily care when parents can't or won't. It suspends parental custody rights but doesn't terminate them. Parents retain the right to petition for termination of the guardianship. The guardian reports to probate court annually via PC 654.

Third-party custody (MCL 722.26c) transfers legal and/or physical custody permanently through the circuit court's family division. The court can order parenting time for the biological parents and child support obligations. There's no annual reporting requirement to the court, but either party can petition to modify the custody order.

If an existing divorce, paternity, or juvenile protective proceeding already involves the child in circuit court, filing a new guardianship in probate court can create jurisdictional complications — the circuit court case generally takes priority and may stay probate proceedings.

Which Path to Choose

Most grandparents and relatives start with probate guardianship, not third-party custody. The standing requirements are broader (any "interested person" can file under MCL 700.5204), the filing is simpler, and the process moves faster — especially if you need temporary authority while the full case plays out.

Third-party custody makes more sense when you've already been appointed as a guardian and want permanent legal custody that doesn't depend on annual court reporting, or when the family situation involves an active circuit court case (like a paternity or divorce proceeding) where guardianship alone wouldn't resolve the custody question.
