Quick answer: Yes, but not easily. To change custody after a Michigan divorce judgment, a parent must first show proper cause or a change in circumstances under MCL 722.27(1)(c). Under Vodvarka v Grasmeyer, ordinary life changes typically are not enough; the change must matter to the child's well-being. If it would alter the child's established custodial environment, the parent must also prove the change serves the child's best interests by clear and convincing evidence.
A Judgment of Divorce sets the custody arrangement, but it does not freeze it forever. Children grow, families move, and circumstances shift. Michigan courts have the authority to revisit custody after a judgment, and they apply a specific legal standard before they do.
That standard exists on purpose. It is meant to prevent unwarranted and disruptive changes to a child's life, which means deciding you want a different schedule is not enough on its own. This guide walks through what the court looks at, in the order it looks at it.

Video transcript: "Here's a Michigan case that every family lawyer should know. In Vodvarka, the Court of Appeals determined what constitutes a change in circumstance that would be relevant to a modification of custody. The court explained that that change has to be significant enough to have an impact on the child's wellbeing, and ordinary life changes that occur after the judgment of divorce is entered are typically not enough. The change has to matter to the child's welfare. This is why documenting substantial developments is so paramount in a custody case. So if you are asking a Michigan court to change the custody arrangements post-divorce, the threshold question is whether or not there has been a legally significant change."
Can Custody Change After a Michigan Divorce Judgment?
Yes. Under MCL 722.27(1)(c), a court may modify or amend its previous custody judgments or orders for proper cause shown or because of a change of circumstances. The statute also adds a second layer of protection: if the change would alter the child's established custodial environment, the court needs clear and convincing evidence that the change is in the child's best interest.
In practice, that gives a parent two hurdles. First, clear the threshold. Second, prove the change is in the child's best interests, by the standard of proof that applies to the situation.
What Is the Threshold: Proper Cause or Change of Circumstances?
In Vodvarka v Grasmeyer, 259 Mich App 499 (2003), the Michigan Court of Appeals explained how courts apply this threshold. A parent can meet it in one of two ways:
Proper cause: an appropriate ground, relevant to at least one of the statutory best interest factors, that has or could have a significant effect on the child's life, enough that the court should reevaluate the custody arrangement.
Change of circumstances: conditions surrounding the child's custody have materially changed since the last custody order, in a way that has or could have a significant effect on the child's well-being.
The court generally addresses this threshold before it looks at the best interest factors. If the parent cannot meet it, the court can decline to go further, and the existing order stays in place. Courts may decide the threshold before holding a full hearing on the merits, unless the facts are disputed.
The key point from Vodvarka is that the change has to be legally significant. Ordinary life changes that happen to any child and any parent, good or bad, are typically not enough. The change has to matter to the child's welfare.
What Kinds of Changes Usually Matter, and What Usually Does Not?
No list decides a case, and every set of facts is different. The table below shows how courts tend to approach common situations.
| Type of Change | How Courts Tend to View It |
|---|---|
| A child getting older or changing grades | Usually viewed as an ordinary life change that happens in any family |
| A parent's new job or work schedule | Courts generally look for an effect on the child's care and well-being, not the change alone |
| A move that disrupts the child's school, routine, or care | May bear on the child's well-being and on the best interest factors |
| Neglect, unsafe conditions, or domestic violence | Relates directly to best interest factors such as MCL 722.23(k) and can be significant |
| One parent undermining the child's relationship with the other | Relates to MCL 722.23(j), the willingness to facilitate a close parent-child relationship |
| A parent's serious change in health or ability to parent | Relates to MCL 722.23(g) and (b) when it affects the child's care |
The pattern is consistent: the question is not whether something changed, but whether the change affects the child in a way that bears on the best interest factors.

What Is the Established Custodial Environment, and Why Does It Matter?
Under MCL 722.27(1)(c), a child has an established custodial environment when, over an appreciable time, the child naturally looks to a parent for guidance, discipline, the necessities of life, and parental comfort. A child can have an established custodial environment with one parent or, in some families, with both.
This matters because it decides how high the bar is. Under Pierron v Pierron, 486 Mich 81 (2010), a court first asks whether the proposed change would modify the established custodial environment. If it would, the parent asking for the change must prove by clear and convincing evidence that it is in the child's best interests. If it would not, the standard is a preponderance of the evidence.
Courts do not decide this by counting overnights alone. In Sabatine v Sabatine (Mich. 2024), the Michigan Supreme Court cautioned courts not to place too much emphasis on the number of overnights a child spends with each parent.
What Best Interest Factors Does the Court Weigh?
Once the threshold is met, the court decides whether the change serves the child's best interests using the twelve factors in MCL 722.23. In summary, they cover:
The emotional ties between each parent and the child
Each parent's capacity to give love, affection, and guidance
Each parent's capacity to meet the child's material and medical needs
How long the child has lived in a stable home, and the value of continuity
The permanence of the existing or proposed home as a family unit
The moral fitness of the parties
The mental and physical health of the parties
The child's record at home, school, and in the community
The child's reasonable preference, if the child is old enough
Each parent's willingness to encourage a close relationship with the other parent
Domestic violence, whether or not directed at or witnessed by the child
Any other factor the court considers relevant
The court weighs all of them together. No single factor controls the outcome.
How Do You Ask a Michigan Court to Change Custody?
A parent asks the court that entered the judgment by filing a motion to modify custody and serving the other parent. The court may refer the matter to the Friend of the Court for information or recommendations, may address the threshold first, and, if the case moves forward, holds an evidentiary hearing. If both parents agree on a change, the court can enter an agreed order, but it still reviews whether the change is in the child's best interests.

What Evidence Helps in a Custody Modification Case?
Because the court starts with the threshold, the record matters from the beginning. Substantial developments should be documented as they happen, not reconstructed later. Documentation parents commonly gather includes:
A dated timeline of the events and changes that affect the child
School, medical, and counseling records that relate to the child's well-being, obtained through proper channels
Text messages, emails, and parenting app records that show relevant conduct
Records of missed exchanges, late pickups, or schedule disputes
Police or agency reports, and records from related court cases
Names of witnesses who saw relevant events
Facts carry more weight than opinions. A record of what happened, when it happened, and how it affected the child is more useful than a general description of frustration.
