Michigan courts determine child custody by applying 12 statutory best interest factors under MCL 722.23, with joint custody available in two forms: joint legal custody (shared decision-making) and joint physical custody (alternating residence). The filing fee for custody cases is $175 without minor children or $255 with minor children as of March 2026. Under MCL 722.26a, Michigan courts must advise parents about joint custody options, and if parents agree on joint custody, courts must grant it unless clear and convincing evidence shows it would harm the child. Sole custody is awarded when parents cannot cooperate or when one parent poses risks to the child's welfare.

Understanding Joint Custody vs. Sole Custody in Michigan
Michigan law recognizes two distinct types of joint custody under MCL 722.26a(7): joint physical custody, where the child resides alternately for specific periods with each parent, and joint legal custody, where parents share decision-making authority on important matters affecting the child's welfare. A court may award joint legal custody while denying joint physical custody, as the Michigan Court of Appeals has confirmed these are separate determinations. In contrast, sole custody grants one parent exclusive physical custody, legal custody, or both, typically when parental cooperation is impossible or one parent presents safety concerns.
Joint Legal Custody Explained
Joint legal custody in Michigan means both parents share decision-making authority for major life decisions affecting their child, including education, healthcare, religious upbringing, and extracurricular activities. Under MCL 722.26a(7)(b), joint legal custody requires parents to agree on basic child-rearing issues such as health care, religion, education, day-to-day decision-making, and discipline. Michigan courts award joint legal custody in approximately 85-90% of divorce cases where both parents are fit and willing to cooperate. The Friend of the Court recommends joint legal custody as the default arrangement when both parents demonstrate the capacity to communicate effectively about their children's needs.
Joint Physical Custody Explained
Joint physical custody under MCL 722.26a(7)(a) means the child resides alternately for specific periods with each parent, creating an established custodial environment with both households. Michigan courts prefer 50/50 parenting time schedules when such arrangements serve the children's best interests, with alternating weeks being the most common schedule where children spend seven days with one parent followed by seven days with the other. Courts consider factors including geographic proximity of parental homes (parents living within the same school district facilitate joint physical custody), work schedules, the child's age and needs, and each parent's involvement in daily caregiving before separation.
Sole Legal Custody
Sole legal custody grants one parent exclusive authority to make major decisions about the child's education, healthcare, religious training, and general welfare without consulting the other parent. Michigan courts award sole legal custody when evidence demonstrates that parents cannot cooperate on basic child-rearing decisions, when one parent has abandoned the relationship with the child, or when communication between parents is so hostile that shared decision-making would harm the child. Under MCL 722.27(1)(c), courts will not change an established custodial environment unless clear and convincing evidence shows the change serves the child's best interests.
Sole Physical Custody
Sole physical custody means the child lives primarily with one parent who provides the child's primary residence, while the other parent typically receives parenting time (visitation). Under sole physical custody arrangements, the non-custodial parent may receive alternating weekends (Friday 6:00 PM to Sunday 6:00 PM), one evening per week, alternating holidays, and extended summer parenting time ranging from 2-6 weeks depending on the child's age. The custodial parent receives child support calculated under the Michigan Child Support Formula, which considers both parents' net incomes, parenting time percentages, and child-related expenses.
Michigan's 12 Best Interest Factors
Michigan courts must evaluate all 12 statutory factors under MCL 722.23 when determining custody, though courts have discretion regarding the weight assigned to each factor. The court does not give equal weight to each factor and may emphasize certain factors based on the specific circumstances of each case.
Factor Analysis Under MCL 722.23
Factor (a) examines the love, affection, and emotional ties between the parties and the child, assessing the depth and quality of the parent-child relationship. Factor (b) considers each parent's capacity and disposition to provide love, affection, guidance, and to continue the child's education and religious training. Factor (c) evaluates each parent's ability to provide food, clothing, medical care, and other material needs. Factor (d) weighs the length of time the child has lived in a stable, satisfactory environment and the desirability of maintaining continuity.
Factor (e) assesses the permanence of the existing or proposed custodial home as a family unit. Factor (f) examines the moral fitness of each party, including conduct relevant to parenting ability. Factor (g) evaluates the mental and physical health of each parent. Factor (h) considers the child's home, school, and community record.
Factor (i) accounts for the reasonable preference of the child if the court considers the child of sufficient age to express a preference, typically around age 12 or older, though no specific age is mandated. Factor (j) examines each parent's willingness and ability to facilitate a close and continuing relationship between the child and the other parent. Factor (k) requires consideration of domestic violence, regardless of whether the violence was directed against or witnessed by the child, as established in Brown v. Brown, 332 Mich App 1 (2020). Factor (l) allows the court to consider any other relevant factor.
How Michigan Courts Award Joint Custody
Michigan courts must advise all parents in custody disputes about joint custody under MCL 722.26a, and either parent may request joint custody consideration. When parents agree on joint custody, the court must grant it unless clear and convincing evidence demonstrates that joint custody would not serve the child's best interests. If parents disagree, the court applies the 12 best interest factors and specifically evaluates whether parents can cooperate and generally agree concerning important decisions affecting the child's welfare.
Requirements for Successful Joint Custody
For joint custody to work effectively, Michigan courts require parents to demonstrate the ability to agree on basic child-rearing issues including healthcare decisions, religious upbringing, educational choices, daily decision-making, and discipline approaches. Courts examine the parties' history of cooperation during the marriage and separation period, their communication patterns, and their willingness to prioritize the child's needs over personal conflicts. Geographic proximity matters significantly for joint physical custody: parents living more than 100 miles apart face additional restrictions under MCL 722.31, the legal residence change statute.
When Courts Deny Joint Custody
Michigan courts deny joint custody when evidence shows an established history of hostility in dealing with child-related issues with no end in sight to the acrimony. The court may find that parental inability to cooperate constitutes a detriment to the child, favoring sole custody instead. Specific circumstances leading to joint custody denial include: documented domestic violence under factor (k), substance abuse issues affecting parenting capacity, mental health conditions that impair judgment, refusal to communicate about the child's needs, and one parent's deliberate interference with the other parent's relationship with the child.
The 100-Mile Rule and Relocation
Under MCL 722.31, a parent whose custody is governed by court order cannot change a child's legal residence to a location more than 100 miles from the child's legal residence at the time the original action was filed without either the other parent's consent or court permission. This statute applies to both joint and sole custody situations and does not apply only when one parent has sole legal custody.
Factors for Relocation Approval
Before permitting a legal residence change exceeding 100 miles, Michigan courts evaluate whether the relocation has the capacity to improve the quality of life for both the child and the relocating parent, and the degree to which each parent has complied with and utilized parenting time under existing court orders. Courts also consider the feasibility of preserving the non-relocating parent's relationship with the child through modified parenting time arrangements, the child's preference if age-appropriate, and whether the move is motivated by a desire to interfere with the other parent's relationship with the child.
Modifying Custody Orders in Michigan
Under MCL 722.27(1)(c), courts may modify custody orders for proper cause shown or because of a change of circumstances. However, courts apply heightened scrutiny when the proposed modification would change the child's established custodial environment, requiring clear and convincing evidence that the change serves the child's best interests rather than the preponderance of evidence standard.
Established Custodial Environment Standard
A custodial environment is established when, over an appreciable time, the child naturally looks to the custodian for guidance, discipline, the necessities of life, and parental comfort. Courts consider the child's age, the physical environment, and both the custodian's and child's inclination toward permanency in the relationship. The Michigan Supreme Court in Stamadianos v. Stamadianos, 425 Mich 1 (1986), emphasized that courts must examine actual circumstances rather than merely referencing the most recent custody order.
Proper Cause vs. Change of Circumstances
Proper cause requires demonstrating that something serious and meaningful has occurred that could affect the child's well-being and would directly impact at least one of the 12 best interest factors. A change of circumstances means something significant has shifted since the last custody order, exceeding a temporary inconvenience. Examples include a parent's relocation, remarriage creating a blended family situation, substance abuse relapse, documented abuse or neglect, or significant changes in the child's needs as they mature.
Child Support Under Joint Custody in Michigan
Joint custody does not eliminate child support obligations under MCL 722.26a. Each parent remains responsible for child support based on the child's needs and each parent's actual resources. The Michigan Child Support Formula, updated January 1, 2025, uses an income share model where each parent's obligation reflects their percentage of combined family income.
How the Formula Works
If one parent earns 70% of the combined net income, that parent bears 70% of the base support obligation regardless of custody type. Net income calculations include wages, salaries, bonuses, commissions, investment income, and imputed income when a parent is voluntarily unemployed or underemployed. The formula accounts for parenting time percentages, so a parent with 50% parenting time pays less support than one with 20% parenting time, all else being equal.
2025 Formula Changes Still in Effect
The 2025 Michigan Child Support Formula reduced the annual ordinary medical expense allowance from $454 to $200 per child, reflecting actual family spending patterns. The presumed age at which children no longer require childcare supervision changed to the last day of the month in which the child turns 13. Support modifications require at least a 10% change or $50 per month difference, whichever is greater, from the current order amount.
Parenting Time Guidelines in Michigan
The Michigan Parenting Time Guideline published by the State Court Administrative Office provides a framework for establishing parenting schedules, though it serves as a guideline rather than a mandatory order. Each county's Friend of the Court may publish specific parenting time schedules, including holiday and summer break allocations for the current year.
Standard Parenting Time Schedules
Typical parenting time schedules include alternating weekends from Friday at 6:00 PM to Sunday at 6:00 PM, one weekday evening per week, and shared holidays on an alternating basis. For Christmas and winter break, odd-numbered years may allocate December 25th through the break to one parent while even-numbered years reverse the arrangement. Summer parenting time for the non-custodial parent typically ranges from 2-6 weeks depending on the child's age and the parents' geographic proximity.
Long-Distance Parenting Time
When parents live 100-180 miles apart (varying by county), they must use specific long-distance schedules featuring extended periods of continuous parenting time. These arrangements often include most of the summer vacation with the non-custodial parent, extended winter and spring breaks, and reduced regular weekends given travel logistics. Courts consider travel costs and the burden on children when fashioning long-distance parenting schedules.
Role of the Friend of the Court
Michigan's Friend of the Court (FOC) offices, established in each county, assist with custody, parenting time, and support matters. The FOC may investigate custody disputes, recommend parenting schedules, mediate conflicts between parents, and enforce existing orders. When parents cannot agree on a schedule, the FOC may recommend a schedule to the court after conducting an investigation.
FOC Enforcement Powers
Upon receiving a written complaint stating specific facts alleging violation of a parenting time or custody order, the Friend of the Court must initiate enforcement proceedings. Enforcement options include contempt proceedings, makeup parenting time, and referral for criminal prosecution in serious cases. The filing fee for custody cases with minor children includes an $80 custody and parenting time fee paid to the Friend of the Court Fund under MCL 600.2529(1)(d)(i).
Domestic Violence and Custody Decisions
Under MCL 722.23(k), Michigan courts must consider domestic violence regardless of whether the violence was directed against or witnessed by the child. The Michigan Court of Appeals in Brown v. Brown, 332 Mich App 1 (2020), confirmed that domestic violence as used in MCL 722.23(k) includes domestic violence as defined under MCL 400.1501 for purposes of the Domestic Violence Prevention and Treatment Act.
Impact on Custody Awards
A history of domestic violence often undermines a parent's ability to demonstrate capacity for effective co-parenting or joint decision-making without intimidation or conflict. Courts may deny joint custody, limit parenting time, or require supervised visitation when domestic violence is established. Importantly, MCL 722.23(j) prohibits courts from negatively considering any reasonable action taken by a parent to protect a child or themselves from sexual assault or domestic violence by the other parent.
Frequently Asked Questions
What is the difference between joint custody and sole custody in Michigan?
Joint custody in Michigan means parents share either physical custody (alternating residence under MCL 722.26a(7)(a)), legal custody (shared decision-making under MCL 722.26a(7)(b)), or both. Sole custody grants one parent exclusive physical custody, legal custody, or both, typically when cooperation is impossible or safety concerns exist. Joint legal custody is awarded in approximately 85-90% of Michigan cases where both parents are fit.
How much does it cost to file for custody in Michigan?
The base filing fee is $175 without minor children or $255 with minor children as of March 2026, per MCL 600.2529. Additional costs include a $25 electronic filing system fee and $20 per motion filed during the case. Fee waivers are available for households earning at or below 125% of federal poverty guidelines (approximately $19,506 for individuals in 2026). Verify current fees with your local Circuit Court clerk.
Can a child choose which parent to live with in Michigan?
Under MCL 722.23(i), courts consider the reasonable preference of a child if the court determines the child is of sufficient age to express a preference. Michigan law sets no specific age, though courts typically give meaningful weight to preferences of children around age 12 or older. The child's preference is one of 12 factors and does not control the outcome.
What are the residency requirements for custody cases in Michigan?
Under MCL 552.9, at least one spouse must have resided in Michigan for 180 days immediately preceding filing and in the county of filing for 10 days. Both the state and county residency requirements are jurisdictional: filing before meeting them results in case dismissal. An exception exists for international custody cases involving minor children when one spouse was born in or is a citizen of another country.
How does parenting time work with joint physical custody?
Joint physical custody typically involves a 50/50 or near-equal parenting time schedule. The most common arrangement is alternating weeks, where children spend seven days with one parent followed by seven days with the other. Courts also approve 2-2-3 schedules (two days with each parent, then three-day weekends alternating) and 3-4-4-3 schedules to reduce transitions while maintaining equal time.
Can I relocate with my child if I have sole custody in Michigan?
Under MCL 722.31, the 100-mile restriction applies to both joint and sole custody arrangements unless one parent has sole legal custody. Even with sole physical custody, you cannot move a child more than 100 miles from their legal residence at the time of filing without the other parent's consent or court permission. Courts evaluate relocation requests by examining whether the move improves quality of life and each parent's compliance with existing orders.
How long does it take to get a custody order in Michigan?
Michigan requires a minimum 60-day waiting period for divorces without minor children and 180 days for divorces with minor children. Uncontested custody agreements can be finalized shortly after the waiting period expires. Contested custody cases requiring Friend of the Court investigation, custody evaluation, or trial may take 6-18 months depending on court schedules and complexity.
What factors lead to joint custody denial in Michigan?
Courts deny joint custody when parents demonstrate an established history of hostility in child-related matters with no end in sight. Specific denial grounds include documented domestic violence, substance abuse affecting parenting capacity, mental health conditions impairing judgment, refusal to communicate, and deliberate interference with the other parent's relationship. Courts evaluate whether parental inability to cooperate harms the child.
Does joint custody affect child support in Michigan?
Joint custody does not eliminate child support obligations under MCL 722.26a. The Michigan Child Support Formula calculates support based on both parents' net incomes and their percentage of parenting time. A parent earning 70% of combined income pays 70% of the base support obligation. Parenting time above 50% reduces the higher-earning parent's support obligation but rarely eliminates it entirely.
How do I modify a custody order in Michigan?
Under MCL 722.27(1)(c), you must demonstrate proper cause or a change of circumstances to modify custody. If the modification would change the child's established custodial environment, you must prove by clear and convincing evidence that the change serves the child's best interests. File a motion with the circuit court, pay the $20 motion fee, and request a hearing. The Friend of the Court may investigate before the court rules.
