When parents in Macomb County divorce or separate, a family court judge decides custody by weighing 12 “best interest of the child” factors set out in Michigan law (MCL 722.23). No single factor decides the outcome. The judge looks at all 12 together and arranges custody around what serves the child, not what either parent prefers. If you are facing a custody dispute, understanding these factors early helps you prepare, and our child custody attorneys can walk you through how each one applies to your family.
The 12 best interest factors are the legal standard every Michigan family court uses to decide custody and parenting time. They come from the Child Custody Act of 1970, codified at MCL 722.23. A judge in the 16th Judicial Circuit Court, which handles family law cases for all of Macomb County, must consider each one and explain on the record how it weighed.
Here is what each factor covers in plain language.

The court looks at the existing bond between each parent and the child. A parent who has been the primary caregiver, who knows the child’s friends, teachers, and routines, tends to show a stronger emotional tie.
This factor asks who can guide the child’s education and any religious upbringing the family follows. Judges consider involvement in homework, school events, and day-to-day moral guidance.
The court weighs each parent’s ability to meet material and medical needs. This is not only about income. A lower-earning parent who consistently handles doctor visits and meals can score well here.
Stability matters. A judge favors keeping a child in a settled, satisfactory home rather than uprooting them, which is why the current living arrangement carries real weight.
The court considers how lasting each proposed home is. A parent with a steady residence and a consistent household structure has an advantage over one whose living situation keeps changing.
This factor is narrow. It addresses conduct that affects how a person functions as a parent, such as substance abuse or domestic violence, not private behavior that has no bearing on the child.
A health condition only counts if it affects parenting ability. The court cannot deny custody based on a disability that does not interfere with caring for the child.
Judges look at how the child is doing in their current school and neighborhood. Strong grades, friendships, and community ties weigh toward keeping those connections intact.
If the court decides a child is old enough to express a reasonable preference, the judge will consider it, usually in a private interview. Michigan sets no fixed age. The judge gauges maturity case by case.
This factor often surprises parents. The court favors the parent more likely to encourage a close relationship with the other parent. Badmouthing or blocking parenting time can hurt your case.
The court considers any domestic violence, whether directed at the child or witnessed by the child. Documented abuse weighs heavily and can override factors that might otherwise favor that parent.
This catch-all lets the judge weigh anything specific to your family that the first 11 factors do not capture, such as a long commute between homes or a special medical need.
Legal custody is the right to make major decisions for the child, while physical custody is where the child actually lives. Michigan courts treat these separately, and the two often look different in practice.
Legal custody covers choices about schooling, medical care, and religious upbringing. Most Macomb County cases end in joint legal custody, meaning both parents share these decisions even when the child lives mainly with one of them. Physical custody sets the day-to-day living schedule and parenting time. It can be joint, with the child splitting time between homes, or sole, with one parent as the primary residence and the other receiving parenting time.

Judges start from the position that a child benefits from a relationship with both parents, so joint custody is common unless evidence shows it would harm the child. The 12 factors drive the decision. If both parents are fit, communicate reasonably, and live close enough to share a schedule, a court usually orders joint custody. Sole physical custody becomes more likely when there is domestic violence, substance abuse, a parent’s absence, or such high conflict that shared decision-making would not work.
Michigan also recognizes an “established custodial environment,” which is the home where the child looks for guidance, discipline, and the necessities of life. If one exists, the parent asking to change it must show by clear and convincing evidence that the change serves the child’s best interests. That is a high bar, and it shapes many Macomb County cases. You can read the full statute on the Michigan Legislature website if you want the exact statutory language.
No. The idea that mothers automatically receive custody is a myth, and Michigan law forbids it. The Child Custody Act requires judges to decide based on the 12 best interest factors without favoring either parent because of sex. A father who has been actively involved and can offer a stable home stands on equal footing. What the court rewards is involvement, stability, and a willingness to support the child’s relationship with the other parent, not gender.
Start by documenting your involvement in your child’s life. Keep a record of school pickups, medical appointments, daily routines, and time spent together. Maintain a stable home and a consistent schedule, because factors four and five reward permanence. Avoid speaking poorly about the other parent in front of your child, since factor 10 weighs your willingness to support that relationship. If safety is a concern, preserve any evidence of domestic violence, including police reports and medical records. An experienced attorney can help you present this information in the way the court expects to see it.
Michigan sets no specific age at which a child can choose. Under factor nine, the judge considers a child’s reasonable preference if the court decides the child is mature enough to express one, often through a private interview. The preference is one factor among 12, not the deciding vote.

Legal custody is the authority to make major decisions about a child’s education, health care, and religious upbringing. Physical custody is where the child lives day to day. Parents can share joint legal custody while one parent has primary physical custody.
Yes. A parent can ask the court to modify custody by showing proper cause or a change in circumstances since the last order. If an established custodial environment exists, the parent seeking change must prove by clear and convincing evidence that the change serves the child’s best interests.
No. Michigan law prohibits favoring a parent based on gender. Judges decide custody using the 12 best interest factors in MCL 722.23, focusing on each parent’s involvement, stability, and ability to meet the child’s needs.
