Michigan Child Custody Laws (2026): 12 Best-Interests Factors, Types, and Your Rights

Michigan courts decide all child custody cases by the best interests of the child, weighing 12 enumerated factors under MCL 722.23 of the Child Custody Act of 1970. The state uses standard legal custody and physical custody terminology, and when the parents disagree no statutory presumption favors joint custody or equal parenting time. Michigan is also notable for its "established custodial environment" doctrine, which raises the evidentiary burden to clear and convincing evidence whenever a modification would disturb an arrangement the child has come to rely on.

How does Michigan decide child custody?

Michigan courts apply the best interests of the child standard under the Child Custody Act of 1970, MCL 722.21 et seq. The circuit court, through its family division, presides over custody matters in divorce, paternity, and separate custody proceedings. MCL 722.26(1) applies the Child Custody Act to all circuit court child custody disputes and actions, and MCL 722.26(2) directs that the action be submitted to the circuit court of the county where the child resides or may be found. The family division is a division of the circuit court, not a separate venue, and probate court does not preside over custody disputes under the act. Unlike many states that rely on a broad, uncodified balancing test, Michigan gives judges a specific roadmap: MCL 722.23 enumerates 12 factors that every court must consider and weigh when deciding custody or parenting time.

Neither parent starts the case with any procedural advantage. Under MCL 722.25(1), the best interests of the child control the outcome, and the 12 factors in MCL 722.23 make no reference to either parent's sex. Michigan courts no longer apply the old presumption that a mother is a better caregiver for young children. The court's focus throughout is on the child's long-term well-being, not on the rights or convenience of either parent.

Types of custody in Michigan

Michigan uses two parallel custody categories. Legal custody refers to the authority to make major decisions about the child's upbringing, including education, health care, and religious instruction. Physical custody refers to the child's primary residence and the day-to-day parenting schedule.

Each type can be sole or joint. Sole legal custody means one parent holds decision-making authority alone. Joint legal custody means both parents share that authority and must consult and agree on major decisions. Sole physical custody places the child primarily with one parent, who typically provides day-to-day care while the other parent has scheduled parenting time. Joint physical custody means the child has a residence with each parent, although the schedule does not have to be equal in time.

Courts may mix and match: joint legal with sole physical custody is the most common arrangement in practice when parents can communicate but one household provides a more stable base for the child.

Does Michigan presume joint or 50/50 custody?

When the parents disagree, Michigan does not presume joint custody or equal parenting time. Under MCL 722.26a, the court must consider joint custody whenever either parent requests it, and the court may even consider it on its own motion if neither parent asks. In a contested case, awarding joint custody requires an affirmative finding that joint custody is in the child's best interests based on the 12 MCL 722.23 factors plus additional considerations about parental cooperation.

Where the parents agree on joint custody, the statute runs the other way. MCL 722.26a(2) provides: "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." In that common scenario the award is mandatory, and the clear and convincing burden falls on the case against joint custody rather than on the parents seeking it.

If the court awards joint custody, it must state its reasons on the record. If the court denies a request for joint custody, it must also state its reasons. The additional factors courts weigh when evaluating joint custody include the parties' ability to cooperate and agree on major decisions, their ability to encourage a close relationship between the child and the other parent, and whether joint custody would affect the child's stability.

A parent who believes joint custody is appropriate should be prepared to demonstrate a history of successful co-parenting communication, not simply a desire for equal time.

The best interests factors Michigan courts weigh

MCL 722.23 enumerates 12 specific factors that every Michigan court must evaluate. No single factor is controlling; the court weighs all of them.

The 12 factors are: (a) the love, affection, and other emotional ties between the parties and the child; (b) the capacity and disposition of each party to give the child love, affection, guidance, and a continuation of the educating and raising of the child in its religion or creed; (c) the capacity and disposition of each party to provide the child with food, clothing, medical care or other remedial care recognized and permitted under the laws of this state, and other material needs; (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 or homes; (f) the moral fitness of the parties; (g) the mental and physical health of the parties; (h) the home, school, and community record of the child; (i) the reasonable preference of the child, if the court considers the child to be of sufficient age to express 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 party, with the statute adding since 2016 PA 95 that "a court may not consider negatively for the purposes of this factor 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"; (k) domestic violence, regardless of whether the violence was directed against or witnessed by the child; and (l) any other factor considered by the court to be relevant to a particular child custody dispute.

Factor (j) (each parent's willingness to support the child's relationship with the other parent) is often pivotal in contested cases. A parent who badmouths the other parent, withholds parenting time, or refuses to communicate typically fares poorly on this factor. The statute carves out an express protection, however: since 2016 PA 95 took effect on August 1, 2016, a court may not count against a parent under factor (j) any reasonable action that parent took to protect the child or themselves from sexual assault or domestic violence by the other parent. Withholding contact as a reasonable protective step is not the same thing as withholding it to punish the other parent, and the statute says so.

Relocation: moving with your child

Michigan's relocation statute, MCL 722.31, provides that a parent with custody may not change the child's legal residence by more than 100 miles from the child's residence at the time the action was filed without first obtaining the other parent's written consent or a court order. The 100-mile rule applies regardless of whether the move crosses a state line.

The statute carries several relief valves, and they matter more than the 100-mile headline. Section 722.31 does not apply at all if the custody order grants sole legal custody to one of the parents. Under subsection (3), the restriction also does not apply if the two parents' residences were already more than 100 miles apart at the time the action was commenced, or if the change results in the child's two legal residences being closer to each other than before. Under subsection (5), every custody or parenting-time order must state the parents' agreement on how a change of legal residence will be handled, and a move made in compliance with that agreed provision falls outside the section entirely. Under subsection (6), a parent who needs a safe location from the threat of domestic violence may move there with the child while the court decides. If none of these applies and the other parent objects, the moving parent must petition the court.

When evaluating a contested relocation request, courts weigh five specific factors under MCL 722.31(4): the capacity of the move to improve the quality of life for both the child and the relocating parent; the degree to which each parent has complied with the existing parenting-time order and whether the parent's plan to move is inspired by a desire to defeat or frustrate that schedule; whether, if the move is permitted, the parenting-time schedule can be modified in a way that preserves and fosters the parental relationship with each parent, and whether each parent is likely to comply with that modification; whether the parent opposing the move is motivated by a desire to secure a financial advantage regarding a support obligation; and any history of domestic violence, regardless of whether it was directed at or witnessed by the child.

Changing a custody order (modification)

Michigan's modification standard under MCL 722.27 has two distinct tiers, depending on whether an established custodial environment exists. An established custodial environment is created when, for an appreciable time prior to the petition, the child has lived with a parent in an environment where the child looks to that parent for guidance, discipline, the necessities of life, and parental comfort.

If an established custodial environment exists with one or both parents, the court may not modify the custody order in a way that would disturb that environment unless the moving party proves by clear and convincing evidence (a high bar) that modification is in the child's best interests. If no established custodial environment exists, the moving party need only prove the change is in the child's best interests by a preponderance of the evidence.

Before reaching the best-interests analysis, the moving party must first show there is proper cause or a change of circumstances. Not every change qualifies; the threshold exists to prevent parents from relitigating custody every time circumstances shift slightly.

If you are facing a custody case in Michigan

Document your day-to-day involvement with the child before, during, and after the case. Courts look at factors such as who attends medical appointments, who communicates with the school, who handles the morning routine, and who facilitates the child's extracurricular activities. Contemporaneous records (calendars, emails, photos with dates) are far more persuasive than testimony alone.

Prepare to demonstrate willingness to cooperate with the other parent. Factor (j) under MCL 722.23 (encouraging the child's relationship with the other parent) is a concrete, recurring consideration. Courts are skeptical of parents who frame every disagreement as a reason to limit the other parent's access. That skepticism does not reach protective conduct: MCL 722.23(j) bars a court from weighing against you, under this factor, any reasonable action you took to protect the child or yourself from sexual assault or domestic violence by the other parent.

Consider whether mediation could resolve your dispute before trial. Michigan courts encourage parents to submit a parenting plan. An agreed plan that reflects the child's routine and serves the child's best interests is almost always approved, sparing the family the cost and stress of a contested hearing.

If modification is your goal, assess whether an established custodial environment exists and be realistic about the evidentiary standard you face. A clear and convincing evidence burden is substantial, and attempting a modification without sufficient grounds can be counterproductive. Before filing a contested modification, ask a Michigan family lawyer for a free case evaluation of whether your grounds meet that burden (attorney advertising).

Frequently Asked Questions

How is child custody determined in Michigan?

Michigan courts apply the best interests of the child standard under MCL 722.23, which enumerates 12 specific factors every judge must weigh. No single factor controls; the court evaluates all 12, including emotional ties, each parent's capacity to provide care, the child's home and school record, and each parent's willingness to support the child's relationship with the other parent.

Does Michigan favor the mother in custody cases?

No. Michigan custody law is gender-neutral: the 12 best-interests factors in MCL 722.23 do not include either parent's sex, and MCL 722.25(1) directs that the child's best interests control the outcome. The old tender-years doctrine that presumed mothers were the better caregivers for young children has no place in this framework. Both parents are evaluated equally under the 12 best-interests factors.

Is Michigan a 50/50 custody state?

Not automatically. When the parents disagree, Michigan has no statutory presumption of joint custody or equal parenting time: courts consider joint custody when a parent requests it, but must find it is in the child's best interests based on the 12 MCL 722.23 factors and the parents' ability to cooperate. When the parents agree on joint custody, MCL 722.26a(2) reverses that and the court must award joint custody unless it determines on the record, by clear and convincing evidence, that joint custody is not in the child's best interests. Note that joint custody does not necessarily mean an equal 50/50 schedule, and many Michigan arrangements involve primary physical custody with one parent and scheduled parenting time for the other.

What is the 'established custodial environment' in Michigan?

An established custodial environment exists when a child has lived with a parent for an appreciable time and looks to that parent for guidance, discipline, the necessities of life, and parental comfort. If an established custodial environment exists, a parent seeking to modify custody must prove by clear and convincing evidence (a higher standard) that modification is in the child's best interests.

At what age can a child choose which parent to live with in Michigan?

There is no set age. Under MCL 722.23(i), the court considers 'the reasonable preference of the child, if the court considers the child to be of sufficient age to express preference.' The child's preference is one of 12 factors and is never automatically controlling. Judges typically give more weight to the preferences of older, more mature children.

How do I change a custody order in Michigan?

You must first show proper cause or a change in circumstances since the prior order. If an established custodial environment exists, you must then prove by clear and convincing evidence that modification is in the child's best interests. If no established custodial environment exists, the lower preponderance-of-the-evidence standard applies.

Can a parent move away with the child in Michigan?

Under MCL 722.31, a parent with custody generally cannot change the child's legal residence by more than 100 miles from where it was at the start of the case without the other parent's written consent or a court order. Several exemptions take a move outside the section entirely: an order granting one parent sole legal custody, residences that were already more than 100 miles apart when the action was commenced, a move that brings the two residences closer together, and a move made in compliance with the parents' agreed relocation provision in the order. A parent needing a safe location from the threat of domestic violence may also move there with the child while the court decides. Where the court does have to rule, it weighs five factors, including the quality-of-life benefit of the move, each parent's compliance with the parenting-time schedule, and any history of domestic violence.
