Michigan gives you a clean checklist — twelve best-interest factors, lettered (a) through (l), that a judge must address one by one.
Then it gives you the rule that quietly decides the case. Before a Michigan court weighs those factors at all, it asks where the child’s established custodial environment sits. That answer sets the burden of proof, and the burden usually sets the outcome.

Quick answer: Michigan decides custody under the Child Custody Act of 1970 using the twelve best-interest factors in MCL 722.23. There is no presumption of joint custody and no presumption of equal parenting time — MCL 722.26a requires the court only to consider joint custody at a parent’s request and to state its reasons on the record. The one place joint custody is close to automatic is where the parents agree on it: the court must then award it unless it finds, on the record and by clear and convincing evidence, that joint custody is not in the child’s best interest. Separately, a parent may not move the child’s legal residence more than 100 miles without the other parent’s consent or the court’s permission.

What are Michigan’s twelve best-interest factors?
MCL 722.23 defines “best interests of the child” as the sum of twelve factors, and Michigan judges address them individually and on the record. Knowing them in order is genuinely useful, because that is the structure your hearing will follow.
- (a) The love, affection and other emotional ties between the parties and the child
- (b) The capacity and disposition to give the child love, affection and guidance, and to continue the child’s education and upbringing
- (c) The capacity and disposition to provide food, clothing and medical care
- (d) The length of time the child has lived in a stable, satisfactory environment, and the desirability of maintaining continuity
- (e) The permanence, as a family unit, of the existing or proposed custodial home
- (f) The moral fitness of the parties
- (g) The mental and physical health of the parties
- (h) The child’s home, school and community record
- (i) The reasonable preference of the child, if the court considers the child old enough to express a preference
- (j) The willingness and ability of each party to facilitate and encourage a close and continuing parent-child relationship between the child and the other parent, or the child and the parents
- (k) Domestic violence, regardless of whether the violence was directed against or witnessed by the child
- (l) Any other factor the court considers relevant
Twelve factors, with (l) as the catch-all. Two are worth pausing on.
Factor (k) is broader than parents expect. It reaches domestic violence “regardless of whether the violence was directed against or witnessed by the child” — so violence between the adults counts even where the child never saw it and was never the target. If safety is part of your case, our guide to how domestic violence affects custody covers what courts look for.
Factor (j) is the one parents most often damage themselves on. It scores each parent’s willingness to support the child’s relationship with the other parent. Blocking calls, scheduling over the other parent’s time, or relaying grievances through the child all register here. Our guide to high-conflict co-parenting strategies covers how to hold a firm line without generating that record.
What is an established custodial environment?
This is the concept to understand before anything else, because it decides which standard of proof applies — and in Michigan the standard of proof frequently decides the case.
MCL 722.27(1)(c) defines it directly:
The custodial environment of a child is established if over an appreciable time the child naturally looks to the custodian in that environment for guidance, discipline, the necessities of life, and parental comfort.
The statute then directs the court to consider the age of the child, the physical environment, and the inclination of the custodian and the child as to permanency of the relationship.
Three things follow that parents routinely get wrong.
It is a factual finding, not a legal label. An established custodial environment (“ECE”) is not the same as legal custody, and it does not track whose name is on the order. A parent with a minority of overnights can share an ECE; a parent with a court order can fail to have one.
It can exist with both parents at once. Nothing in the definition makes it exclusive. Where a child looks to both parents in that way, the ECE exists with both.
It sets the burden. Where a proposed change would alter the established custodial environment, the court may not order it “unless there is presented clear and convincing evidence that it is in the best interest of the child.” Where the change would not alter the ECE, the ordinary preponderance standard applies. That gap is large, and it is why Michigan custody hearings so often open with argument about where the ECE sits rather than about the twelve factors.
One caution on how this is often described. The statute states the standard of proof passively — “unless there is presented clear and convincing evidence” — and does not name which party carries it, nor does it direct the court to make the ECE finding before the factor analysis. Those are matters of Michigan case law and practice rather than of the statutory text.
Does Michigan presume joint custody?
No. Michigan has no general presumption in favour of joint custody and no presumption of equal parenting time. What MCL 722.26a creates is narrower, and it comes in two parts that are constantly merged into one.
Part one — a duty to consider, on request. In custody disputes between parents, the parents must be advised of joint custody, and “at the request of either parent, the court shall consider an award of joint custody, and shall state on the record the reasons for granting or denying a request.” That is a procedural obligation to think about it and explain the answer. It carries no burden shift and puts no thumb on the scale. Ask for joint custody and you are entitled to a reasoned answer — not to joint custody.
Part two — near-automatic joint custody where the parents agree. MCL 722.26a(2): “If the parents agree on joint custody, the court shall award joint custody unless the court determines on the record, based upon clear and convincing evidence, that joint custody is not in the best interests of the child.”
That second provision is the source of most confusion. Quoted without its opening condition — if the parents agree — it reads like a strong statewide presumption of joint custody. Read with it, it is an agreement-protection rule: where two parents have settled on joint custody, a judge needs clear and convincing evidence to override them. In a contested case it does no work at all. That distinction is why our 50-state comparison of custody laws places Michigan in the agreement-conditioned group rather than among the presumption states.
Two further points from the same section. Joint custody is defined disjunctively — it can mean shared decision-making, shared physical time, or both, so “joint custody” in a Michigan order needs reading rather than assuming. And when deciding joint custody the court must consider, alongside the twelve factors, “whether the parents will be able to cooperate and generally agree concerning important decisions affecting the welfare of the child.” Cooperation is a separate gate.
Notably, MCL 722.26a has never been amended since it was added in 1980, effective January 1981.
Can a child choose which parent to live with in Michigan?
No, and Michigan sets no age in the statute. Factor (i) directs the court to consider “the reasonable preference of the child, if the court considers the child to be of sufficient age to express preference” — a judicial assessment of this child, not a birthday.
The preference is one factor of twelve, and it is qualified twice over: the child must be old enough in the court’s view, and the preference must be reasonable. A preference traced to lax rules at one house, or to a parent’s coaching, carries little weight. Our guide to how courts handle teenagers’ custody preferences covers raising it carefully.
How do you file for custody in Michigan?
Custody is decided in the family division of the circuit court for the county where the child lives, subject to the six-month home-state rule under the UCCJEA.
- Pick the right case. Married parents resolve custody inside the divorce. Unmarried parents proceed under the Child Custody Act once parentage is established.
- File in the circuit court for the county, using the state’s SCAO-approved forms where they apply.
- Expect the Friend of the Court. This is Michigan’s distinctive piece of machinery. The FOC office attached to each circuit court investigates, makes recommendations on custody and parenting time, and handles enforcement. In most Michigan cases the FOC recommendation arrives before the judge rules, and it carries real weight — treat the FOC interview as seriously as a hearing.
- Attend mediation or the FOC conference as your county directs.
- Expect the judge to walk the twelve factors on the record.
- Finalise by consent order or after an evidentiary hearing.
Filing fees are set by statute and county schedule and commonly run a few hundred dollars, with a fee waiver available on an affidavit of indigency. Our general guide to how to file for custody covers the sequence across states.
How do you change a Michigan custody order?
Two tiers, and most motions fail at the first.
Tier one — the threshold. Under MCL 722.27(1)(c) a court may modify a previous judgment or order only “for proper cause shown or because of change of circumstances.” Without one of those, the court does not reach the merits.
Tier two — the standard of proof. If the modification you want would change the child’s established custodial environment, you must show by clear and convincing evidence that the change is in the child’s best interest. If it would not, the ordinary standard applies.
That structure explains a pattern that frustrates parents: a motion can be denied without anyone ever weighing whether the proposed arrangement would be better, because the moving parent never cleared the threshold.
Modification authority runs until the child turns 18, and — subject to the support and parenting time enforcement act — as late as 19 years and 6 months for certain purposes.
Our step-by-step guide to how custody modification works covers the mechanics, and Michigan child support is recalculated separately when the overnight split changes.
What is Michigan’s 100-mile rule?
Michigan’s relocation statute, MCL 722.31, works differently from every other state in this cluster — and its most important feature is a legal fiction.
Where a child’s custody is governed by court order, the child is deemed to have a legal residence with each parent. A parent may not change the child’s legal residence to a location more than 100 miles from the child’s legal residence at the time the action commenced, without either the other parent’s consent or the court’s permission.
Note what is being measured. Not how far you are moving from your own current address — how far the child’s new legal residence sits from the residence in place when the case began. And the limit is distance from that starting point, not from the other parent.
The exceptions, taken from the statute:
| Exception | Effect |
|---|---|
| The other parent consents | No court permission needed |
| The court permits the change after applying the § 722.31(4) factors | Move allowed |
| The parents’ residences were already more than 100 miles apart when the order issued | The section does not restrict a further change |
| The move brings the two residences closer together | The section does not apply |
| One parent has sole legal custody | The 100-mile restriction does not apply to that parent |
Two things the statute conspicuously does not contain. There is no advance-notice requirement — no notice period, no required contents, no deadline to file a motion or an objection. Michigan is the opposite of Pennsylvania here, which runs a 60-day certified-mail notice and a 30-day objection window. And the statute assigns no burden of proof and creates no presumption for or against relocation; it directs only that the court consider the § 722.31(4) factors “with the child as the primary focus.”
The absence of a notice rule is not permission to move quietly. Your own order may contain a notice clause, and MCL 722.31(5) contemplates that orders address the subject. Read your order before you sign a lease.
Where do unmarried parents stand in Michigan?
Michigan gives a clear statutory answer, and it sits outside the Child Custody Act.
Under MCL 722.1006, part of the Acknowledgment of Parentage Act, after an acknowledgment of parentage is signed “the mother has initial custody of the minor child, without prejudice to the determination of either parent’s custodial rights, until otherwise determined by the court or otherwise agreed upon by the parties in writing and acknowledged by the court.”
The same section immediately limits what that means: the grant of initial custody to the mother “does not, by itself, affect the rights of either parent in a proceeding to seek a court order for custody or parenting time.”
So Michigan’s rule is a holding position, not an advantage. The mother holds initial custody until a court acts; once a father files, the initial-custody grant is expressly not a factor weighing against him. That places Michigan alongside Ohio, which makes an unmarried mother the sole residential parent by statute, and apart from Pennsylvania, whose custody chapter contains no marital-status default at all.
The practical sequence for an unmarried father is: sign or obtain an acknowledgment of parentage, then file for custody and parenting time under the Child Custody Act. Our guide to fathers’ custody rights covers the broader picture.
Frequently Asked Questions
Does Michigan favour 50/50 custody?
No. Michigan has no presumption of joint custody and no presumption of equal parenting time. MCL 722.26a requires the court to consider joint custody at either parent’s request and to state its reasons on the record — a duty to explain, not a tilt toward any outcome. The one exception is where both parents agree on joint custody, in which case the court must award it unless clear and convincing evidence shows it is not in the child’s best interest.
What is an established custodial environment in Michigan?
It exists where, over an appreciable time, the child naturally looks to that parent for guidance, discipline, the necessities of life and parental comfort. It is a factual finding rather than a legal status, it can exist with both parents at once, and it matters because a change that would alter it requires clear and convincing evidence rather than the ordinary standard.
At what age can a child decide which parent to live with in Michigan?
There is no age. Factor (i) of MCL 722.23 asks for the child’s reasonable preference if the court considers the child old enough to express one. It is one factor among twelve and never decides the case by itself.
How far can I move with my child in Michigan?
Not more than 100 miles from the child’s legal residence at the time the action began, without the other parent’s consent or the court’s permission. The rule does not apply where the parents’ residences were already more than 100 miles apart, where the move brings the residences closer together, or where one parent has sole legal custody.
Does Michigan require notice before relocating?
MCL 722.31 contains no notice requirement — no notice period, no required contents, no objection deadline. That is unusual; Pennsylvania, for instance, requires 60 days’ certified-mail notice. But your own custody order may impose a notice clause, and moving in a way that damages the other parent’s parenting time is something a court can weigh later.
Does an unmarried father have custody rights in Michigan before going to court?
Not initially. Under MCL 722.1006 the mother has initial custody after an acknowledgment of parentage is signed, until a court determines otherwise or the parties agree in writing. That grant is expressly without prejudice — it does not, by itself, affect either parent’s rights once a custody or parenting-time case is filed.
