Michigan Child Custody: Best Interests, Parenting Time, and Relocation

Michigan child custody laws, set out in the Child Custody Act of 1970, give judges one question to answer in every case: what arrangement serves the child’s best interests? Courts answer it by splitting custody into two kinds, legal and physical, awarding each either solely to one parent or jointly, and weighing twelve specific factors on the record. Once a stable living situation is in place, the law makes it deliberately hard to disturb.

Legal Custody and Physical Custody

Legal custody is the authority to make the big decisions in a child’s life: schooling, medical treatment, religious upbringing. Parents who share joint legal custody have equal say and must reach agreement before acting. Sole legal custody lets one parent make those calls alone.¹

Physical custody is about where the child lives day-to-day. Sole physical custody means the child lives primarily with one parent and the other has parenting time. Joint physical custody means the child splits time between both homes, and the split does not have to be an even 50/50. Whichever parent has the child at the moment handles the routine calls like bedtimes and meals.¹

Courts are required to tell parents that joint custody is an option. If either parent asks for it, the judge must consider it and explain on the record why it was granted or denied. When both parents agree on joint custody, the court must award it unless clear and convincing evidence shows the arrangement would not serve the child’s best interests.¹

Joint custody does not cancel child support. Each parent remains responsible for support based on the child’s needs and each parent’s actual resources, and a joint custody order on its own is not grounds to modify an existing support obligation.¹

The Twelve Best-Interests Factors

Michigan judges must individually evaluate twelve factors when deciding custody. No single factor controls, and the court weighs them against the specific family’s circumstances.²

The love, affection, and emotional ties between the child and each parent.
Each parent’s capacity and disposition to give love, guidance, and continuing education and religious upbringing, if any.
Each parent’s capacity to provide food, clothing, medical care, and other material needs.
How long the child has lived in a stable, satisfactory environment, and the desirability of maintaining continuity.
The permanence of the existing or proposed custodial home.
The moral fitness of each parent.
The mental and physical health of each parent.
The child’s home, school, and community record.
The child’s own preference, if the judge finds the child mature enough to express a meaningful one.
Each parent’s willingness to support a close and continuing relationship between the child and the other parent. A parent who takes reasonable steps to protect a child from abuse or domestic violence cannot be penalized under this factor.
Any history of domestic violence, whether or not the child witnessed it or was targeted.
Any other factor the judge considers relevant.

The domestic violence factor and the cooperative-parenting factor carry significant practical weight. A parent who actively undermines the child’s relationship with the other parent, or one with a documented history of violence, faces a steep uphill battle.

The Established Custodial Environment

Before changing any custody arrangement, a Michigan court must first decide whether an established custodial environment exists. A child has one with a parent when, over a meaningful period, the child naturally looks to that parent for guidance, discipline, everyday needs, and comfort. The court also considers the child’s age, physical surroundings, and how permanent the relationship feels to the child and the parent.³

A child can have an established custodial environment with both parents at the same time. That is common in joint physical custody arrangements where the child spends substantial time in each home.⁴

This finding controls how much evidence the moving party needs. If an established custodial environment exists, a parent asking to change custody must present clear and convincing evidence that the change serves the child’s best interests. That is a high bar, designed to shield children from unnecessary upheaval. If no established custodial environment exists, the lower preponderance-of-the-evidence standard applies.³

Parenting Time

Michigan law presumes children benefit from a strong relationship with both parents. Parenting time must be granted at a frequency and duration reasonably designed to promote that relationship.⁵

A child has a right to parenting time with each parent. That right can be restricted or denied only if clear and convincing evidence shows contact would endanger the child’s physical, mental, or emotional health. Courts take this default seriously. Even parents with troubled histories often receive supervised parenting time rather than no contact at all.⁵

Parents can work out a flexible schedule on their own. If they cannot, the court issues a detailed order fixing exact dates, times, holidays, and summer vacation. An order can also include conditions tailored to the family:

Dividing transportation responsibilities and costs
Requiring parenting time to occur with a third party present (supervised visitation)
Restricting who else may be present during visits
Requiring a bond to guarantee compliance

These conditions are enforceable through the Friend of the Court.⁵

Modifying an Existing Custody Order

Changing an existing order in Michigan is intentionally difficult. The parent requesting the change must first show proper cause or a genuine change in circumstances before the court will revisit the best-interests analysis at all. That threshold stops parents from relitigating custody every time they are unhappy.³

The change has to have a real effect on the child’s well-being. A parent earning more money, starting a new relationship, or moving to a slightly different neighborhood does not clear the bar. Courts look for developments that materially affect the child, such as a parent developing a substance abuse problem, a significant shift in the child’s needs, or a pattern of one parent blocking the other’s parenting time.

If the court finds proper cause or changed circumstances, it then works through the twelve factors. If an established custodial environment exists, the parent seeking the change still faces the clear-and-convincing-evidence standard on top of that.³

Moving With the Child: The 100-Mile Rule

If you share legal custody, you generally cannot move the child’s legal residence more than 100 miles from the current home without the other parent’s written consent or court permission. Any move to another state requires court approval regardless of distance.⁶

Court permission is not needed if the move is under 100 miles, if the other parent consents, if you have sole legal custody, if the two homes were already more than 100 miles apart when the custody case began, or if the move would actually bring the two homes closer together.⁶

When approval is required, the judge weighs five factors:

Whether the move has the potential to improve the quality of life for both the child and the relocating parent
Whether each parent has followed the current parenting time schedule, and whether the move is motivated by a desire to interfere with it
Whether a modified schedule can preserve both parent-child relationships, and whether each parent is likely to comply
Whether the parent opposing the move is motivated by a desire to gain a financial advantage on child support
Whether domestic violence is a factor

The relocating parent carries the burden on each applicable factor by a preponderance of the evidence. Moving without permission when it was required can lead the court to order the child’s return and can hurt the relocating parent’s credibility in future proceedings.⁶

Unmarried Parents

When parents are not married, the father does not automatically have custody or parenting time rights. Signing an Acknowledgment of Parentage at the hospital or afterward legally establishes paternity, but it does not, on its own, create a custody or parenting time order.⁷

To get enforceable rights, an unmarried father has to file a petition. The court then applies the same best-interests factors used in any custody case. Until a court order is in place, the mother of a child born outside of marriage has sole legal custody by default. Without a court order, you have no legally enforceable right to time with your child, even if your name is on the birth certificate.

The Friend of the Court

Michigan has an institution that plays a central role in nearly every custody case: the Friend of the Court (FOC). Every county has an FOC office, and it functions as an arm of the circuit court in domestic relations matters.

The FOC investigates custody and parenting time disputes when ordered by the court and files a written report and recommendation. Each parent has the right to meet with the investigator before a recommendation is made. The FOC also offers mediation. If domestic violence has occurred, FOC mediation can proceed only if the survivor agrees and safety precautions are in place.⁸

Beyond investigation and mediation, the FOC enforces existing custody and parenting time orders when a parent is not complying, and provides form motions and instructions so parents can file certain modifications without an attorney.⁹

Grandparent Visitation

Grandparents can petition for court-ordered visitation, but only in specific circumstances and against a standard that strongly favors the parents’ decisions. A grandparent can file when:

The child’s parents are in the middle of a divorce, separate maintenance, or annulment proceeding
The parents are already divorced or legally separated
The grandparent’s own child (the child’s parent) has died
The parents were never married, are living separately, and paternity has been legally established
The child has been placed in someone else’s legal custody or is not living with either parent
The grandparent provided an established custodial environment for the child during the year before filing

Even then, the court presumes that a fit parent’s decision to deny grandparent visitation does not create a substantial risk of harm to the child. The grandparent must overcome that presumption by a preponderance of the evidence, showing that denying visitation actually creates a substantial risk of harm to the child’s mental, physical, or emotional health. If the child is adopted, grandparent visitation rights are terminated, with one exception: a stepparent adoption by the spouse of the grandparent’s own child who has died.¹⁰

Military Deployment

Michigan protects parents called to deployment. A court cannot use the length of deployment as a factor in the best-interests analysis, and it cannot permanently change the custody arrangement that was in place on the date the parent was called. The court may enter a temporary order during deployment, but only on clear and convincing evidence that the temporary change serves the child’s best interests.¹¹

When deployment ends, the parent must inform the court of their return date within 30 days, and the court reinstates the pre-deployment order. If the other parent files a motion to change custody during deployment, the deployed parent can file a written application to stay the proceedings at any stage, and the court must grant it.¹¹

When a Parent or Child Is in Another State

Michigan follows the Uniform Child-Custody Jurisdiction and Enforcement Act. Michigan courts have jurisdiction when Michigan is the child’s “home state,” meaning the child has lived here for at least six consecutive months before the case is filed. If the child recently left Michigan but a parent still lives here, Michigan keeps home-state jurisdiction for six months after the child’s departure.¹²

If another state already has an existing custody order, Michigan courts generally cannot override it. The state that issued the original order typically keeps jurisdiction to modify it. Figuring this out early can save months of litigation in the wrong court.
