What types of custody does Michigan recognize?
Michigan recognizes two types of custody, legal and physical, and either one can be sole or joint. Michigan Legal Help’s guide to custody and parenting time says legal custody is “the right to make important decisions about your children, such as where they go to school, what religion they are (if any), and major medical decisions,” while physical custody refers to the children’s living arrangements.
Sole custody means only one parent has custody. Joint custody means the parents share it. A family can have a mix, because the two types are separate questions: parents who share legal custody make the important decisions together, and parents who share physical custody each have the children living with them some of the time.
| Term | What it means | Where it comes from |
|---|---|---|
| Legal custody | The right to make important decisions about the child | Michigan Legal Help |
| Physical custody | The child’s living arrangements | Michigan Legal Help |
| Joint custody | An order that the child lives alternately with each parent for specific periods, that the parents share important decisions, or both | MCL 722.26a(7) |
| Parenting time | The time a child spends with each parent when the parents do not live in the same home | Michigan Parenting Time Guideline |
| Established custodial environment | A settled arrangement the child naturally looks to for guidance, discipline, necessities and comfort | MCL 722.27(1)(c) |
What are the best-interest factors in Michigan?
Michigan judges decide contested custody by the best interests of the child, which the law defines as the “sum total” of 12 factors. MCL 722.23 lists them, lettered (a) through (l), and MCL 722.25 says the best interests of the child control when a dispute is between the parents.
| Factor | What the court looks at |
|---|---|
| (a) | Love, affection and other emotional ties between each party and the child |
| (b) | Each party’s capacity and disposition to give love, affection and guidance, and to continue the child’s education and raising in their religion or creed, if any |
| (c) | Each party’s capacity and disposition to provide food, clothing, medical care and other material needs |
| (d) | How long the child has lived in a stable, satisfactory environment, and the desirability of keeping that continuity |
| (e) | The permanence, as a family unit, of the existing or proposed custodial home or homes |
| (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 child’s reasonable preference, if the court considers the child old enough to express one |
| (j) | Each party’s willingness and ability to encourage a close and continuing relationship between the child and the other parent |
| (k) | Domestic violence, whether or not it was directed against or witnessed by the child |
| (l) | Any other factor the court considers relevant to the dispute |
Factor (j) carries a limit worth reading closely. A court may not count against a parent “any reasonable action taken by a parent to protect a child or that parent from sexual assault or domestic violence by the child’s other parent.”
Our guide to the best interest of the child factors covers how this kind of list works in practice, across states.
What is an established custodial environment in Michigan?
An established custodial environment exists when, over an appreciable time, the child naturally looks to the custodian for care. MCL 722.27 describes it as an environment where the child looks to the custodian “for guidance, discipline, the necessities of life, and parental comfort.” The child’s age, the physical environment and how permanent the relationship seems to the custodian and the child also count.
This question matters because it sets how much a parent has to prove. Under the statute, a court shall not change an established custodial environment unless there is clear and convincing evidence that the change is in the child’s best interest. Michigan Legal Help’s overview of a custody case sets out both paths: where there is an environment, the party who wants to change it must meet the clear and convincing standard, and where there is none, the winning party is the one who shows by a preponderance of evidence that the proposed arrangement serves the child’s best interests.
Where a child sleeps does not settle it. The Michigan Custody Guideline from the State Court Administrative Office says “just because a child is living with a parent, that does not necessarily mean that an established custodial environment exists.” It adds that both parents may have one with the child.
How does joint custody work in Michigan?
Joint custody is an option the court has to take seriously whenever a parent asks for it. Under MCL 722.26a, parents in a custody dispute must be advised of joint custody, and if either parent requests it the court must consider it and state its reasons on the record for granting or denying the request.
The court weighs the same 12 best-interest factors plus one more question: whether the parents “will be able to cooperate and generally agree concerning important decisions affecting the welfare of the child.” If the parents agree on joint custody, the court shall award it unless it finds on the record, by clear and convincing evidence, that joint custody is not in the child’s best interests.
Joint custody does not have to mean equal time. The Michigan Custody Guideline says a judge could “award joint custody and not equally divide the time the child spends with each parent.” The statute lets the order say when the child lives with each parent, or simply require that physical custody be shared in a way that assures continuing contact with both. During a parent’s time, that parent decides routine matters.
Does joint custody end child support in Michigan?
No. The statute says joint custody “shall not eliminate the responsibility for child support,” and that each parent is responsible based on the child’s needs and each parent’s actual resources. An order of joint custody is not, in and of itself, grounds for modifying a support order.
What does sole custody mean in Michigan?
Sole custody means only one parent has custody, and parents searching for “full custody” usually mean this. The same best-interest analysis applies, and when joint custody is requested the court also asks whether the parents can cooperate on important decisions.
A sole custody order does not usually end the other parent’s place in the child’s life. Under MCL 722.27a, a child has a right to parenting time with a parent unless it is shown by clear and convincing evidence that it would endanger the child’s physical, mental or emotional health. Sole legal custody does change one thing: the 100-mile rule described below does not apply when the order grants it to one parent.
How does parenting time work in Michigan?
Parenting time is granted by the child’s best interests, starting from a presumption that a strong relationship with both parents serves the child. MCL 722.27a says parenting time should come in a frequency, duration and type reasonably calculated to promote that relationship. When parents agree on terms, the court shall order them unless it finds by clear and convincing evidence that they are not in the child’s best interests.
The statute also gives the court a list for deciding how much time, and what kind. It includes the child’s special needs, the reasonable likelihood of abuse or neglect during parenting time, the burden of travel on the child, whether a parent can reasonably be expected to follow the order, and whether a parent has frequently failed to exercise reasonable parenting time.
Either parent can ask for specific terms, and the statute says parenting time shall then be granted in specific terms. An order can also divide transport duties and costs, set exact pick-up and return times, and add other reasonable conditions. Our guide to writing a parenting plan covers the kinds of detail that make terms workable.
What are the Michigan parenting time guidelines?
The Michigan Parenting Time Guideline is a State Court Administrative Office publication, and it says of itself: “This Guideline is a tool and not the law.” It does not set one default schedule. In its words, “there is not one standard schedule that works best for all families.”
What happens when parenting time is missed in Michigan?
The guideline describes makeup parenting time through the Friend of the Court. Its checklist asks whether a written complaint reached the office within 56 days of the missed time, and it says the makeup time must occur within one year and must be the same type as the time that was denied. It also warns that the office may not be able to help when parents exercise parenting time “as agreed” or “reasonable parenting time,” which is one practical reason specific terms can matter.
Can a child choose which parent to live with in Michigan?
A child does not simply choose, and the factor on a child’s wishes does not name an age. Factor (i) of MCL 722.23 covers the child’s reasonable preference “if the court considers the child to be of sufficient age to express preference.”
The Michigan Custody Guideline says many judges speak to children in chambers and must make a record of the interview, though they do not have to tell the parents what the child said, only that the preference was considered. It adds: “The child’s preference does not outweigh all of the other factors of the Child Custody Act.”
What does the Friend of the Court do in a Michigan custody case?
The Friend of the Court is an office that assists judges with custody, parenting time and child support decisions. Michigan Legal Help’s overview adds that “Friend of the Court practices differ from court to court,” so a parent’s experience in one county may not match another.
A recommendation from that office is not the final word. It “is not a court order until it is signed by a judge,” and a parent gets a chance to object first. A parent who objects gets a hearing in front of the judge.
Is mediation required in a Michigan custody case?
It can be. The overview says the judge may order parents into an alternative dispute resolution process, which might be Friend of the Court mediation, another Friend of the Court meeting or a private mediator. MCL 552.513 says that the office’s process includes screening for domestic violence, a protection order, child abuse or neglect and other safety concerns. Our guide to preparing for custody mediation covers what to bring and how to get ready.
What is the 100-mile rule in Michigan?
The 100-mile rule stops a parent under a custody order from moving a child’s legal residence more than 100 miles from where it was when the case started, unless the other parent consents or the court permits it. That rule is in MCL 722.31. Michigan Legal Help also says that, after a final order, the child’s residence may not be moved outside Michigan without the court’s approval.
The rule does not apply in every case. It does not apply when the order grants sole legal custody to one parent, when the child’s two residences were already more than 100 miles apart when the case began, or when the move brings the two residences closer together.
When the court does have to decide, the child is “the primary focus” and five factors apply:
- Whether the move can improve quality of life for both the child and the relocating parent.
- How far each parent has complied with and used their parenting time, and whether the move is meant to defeat the schedule.
- Whether the schedule can be changed in a way that preserves each parent’s relationship with the child, and whether each parent is likely to comply.
- Whether the parent opposing the move is motivated by a financial advantage on support.
- Domestic violence, whether or not it was directed against or witnessed by the child.
A parent who needs a safe location away from the threat of domestic violence may move there with the child until the court makes its decision. Our guide to moving out of state with joint custody covers the wider questions a move raises.
What are Michigan custody laws for unmarried parents?
When unmarried parents have no court order, the mother has initial custody, and that remains true after parentage is established. Michigan Legal Help says a biological father who was not married to the mother is “not the legal father” until he takes steps to establish paternity, either by signing an affidavit of parentage with the other parent or by getting a court order. MCL 722.1003, which calls the form an acknowledgment of parentage, sets out how it works.
That initial custody is a starting point. MCL 722.1006 says it lasts until a court decides otherwise or the parents agree in writing and the court acknowledges it, and that it does not, by itself, affect either parent’s rights in a custody or parenting time case. Until then, Michigan Legal Help says, the mother has sole authority to make decisions for the child and does not need court permission to move with the child.
Legal paternity must be established before a father can file a custody case. Michigan Legal Help also says that signing the affidavit waives the right to a paternity test, so it is worth reading before signing. Our guide to keeping a record as an unmarried parent covers what to write down while that is being sorted out.
Do grandparents have visitation rights in Michigan?
Grandparents can ask for a grandparenting time order only in listed situations, and they start behind a presumption that favors a fit parent’s decision. MCL 722.27b covers cases such as a pending or finished divorce, a grandparent’s child who has died, or unmarried parents who do not share a household and have established paternity.
The statute presumes that “a fit parent’s decision to deny grandparenting time does not create a substantial risk of harm to the child’s mental, physical, or emotional health.” A grandparent must overcome that by a preponderance of the evidence, and must then show that the order is in the child’s best interests.
A custody dispute between a parent and a third person also starts in the parent’s favor. MCL 722.25 presumes the child’s best interests are served by custody with the parent or parents unless the contrary is established by clear and convincing evidence.
How do you file for custody in Michigan?
A custody case generally starts in the Family Division of the Circuit Court in the county where the child lives, as long as Michigan is the child’s home state. Michigan Legal Help says the child must generally have lived in Michigan with a parent for at least six months in a row right before filing, or since birth. MCL 722.1201 is the jurisdiction statute behind that rule.
The parent who receives the case has a deadline to respond. Michigan Legal Help gives 21 days from service if the papers were handed to that parent in person, and 28 days if they were served by mail or while outside Michigan.
How do you change a custody order in Michigan?
A parent has to show proper cause or a change of circumstances before a Michigan court will modify a custody order. That is the threshold in MCL 722.27, and Michigan Legal Help says it “is more significant than normal life changes,” something that has or could have a big impact on the child’s well-being.
If the change would alter an established custodial environment, the clear and convincing standard applies as well. The law favors stability here: in Michigan Legal Help’s words, “custody arrangements for children should remain stable.” Our guide to changing a custody order covers how modification works and what usually has to be shown.
Can both parents see the child’s records in Michigan?
Yes, unless a protective order says otherwise. MCL 722.30 says a parent shall not be denied access to records or information about their child because they are not the custodial parent. It names medical, dental and school records, day care provider’s records, and notification of meetings about the child’s education.
The Parenting Time Guideline adds a practical point: parents are individually responsible for getting information about events and activities in their child’s life. Asking the school or doctor directly is usually simpler than waiting to be told.
Where does a written record fit in a Michigan case?
A written record helps because several Michigan questions turn on what happened over time, not on one day. How long a child has lived in a stable environment, who the child looks to for care, and how each parent has used their parenting time are all questions about a pattern. No Michigan source we read says a judge requires a calendar or a log, so treat this as practical preparation and not a legal rule.
“What I usually tell people is that it is VERY important to begin documenting and preparing things for me, or whoever your divorce attorney is, early enough.”
That advice from Cojocar, in How Can I Prepare for a Custody Battle?, is about timing, and it fits the factors above. A note written the same day holds details that a memory months later may not. Keep to your own day: the school run, the doctor’s visit, the homework, the exchange that went smoothly and the one that did not.
The Michigan Custody Guideline shows what an evaluator may look at. A child’s “home record” can cover siblings, health, discipline and whether the child is outgoing or withdrawn, and the school record may show academic progress and referrals to the counselor. Judges may also look at other evidence, including school and community records.

Frequently asked questions
Is Michigan a 50/50 custody state?
The statutes we read do not set equal time as a starting point. MCL 722.27a presumes a strong relationship with both parents serves the child, and the Michigan Custody Guideline says a judge can award joint custody with or without dividing the time equally.
How do you get full custody in Michigan?
Michigan sources use the term sole custody. If the parents disagree, the judge decides by the 12 best-interest factors in MCL 722.23, and if an established custodial environment would change, the clear and convincing standard applies.
At what age can a child decide where to live in Michigan?
MCL 722.23 does not name an age. The court considers a child’s reasonable preference if it considers the child to be of sufficient age, and that preference is one factor among 12.
Does the mother automatically get custody in Michigan if the parents are not married?
She has initial custody until a court decides otherwise or the parents reach a written agreement the court acknowledges. MCL 722.1006 says this does not, by itself, affect either parent’s rights in a custody or parenting time case.
Does Michigan’s 100-mile rule apply to every move?
No. MCL 722.31 does not apply if the order grants sole legal custody to one parent, if the two residences were already more than 100 miles apart when the case began, or if the move brings them closer together. The other parent can also consent.
Is a Friend of the Court recommendation a court order?
No. Michigan Legal Help says a recommendation is not a court order until a judge signs it, and a parent can object first and have a hearing in front of the judge.
Are the Michigan parenting time guidelines the law?
No. The Michigan Parenting Time Guideline says it is a tool and not the law, and that there is not one standard schedule that works best for all families.
How we researched this
We read 17 sources for this guide: 12 sections of the Michigan Compiled Laws, two Michigan Legal Help guides, two State Court Administrative Office guidelines and one Michigan attorney’s published article. We read each statute on the Michigan Legislature’s site on November 6, 2026, when it listed the compiled laws as complete through PA 114 of 2026. The Michigan Custody Guideline dates from March 2002 and says its recommendations are professional judgment, so we used it for practical description and relied on the statutes for the rules. Every factual claim was matched to a passage in one of these sources before publishing.
