Courts in Michigan do not change custody orders lightly. Knowing the legal standard can help you decide whether your situation is strong enough to pursue.
The legal threshold you must meet
Under MCL 722.27(1)(c), a court may only modify an existing custody order if you prove proper cause or a change of circumstances. This requirement prevents courts from revisiting settled arrangements over routine disagreements. Both grounds must connect to at least one of the 12 best interests of the child factors.
What qualifies as a significant change
Not every shift in family life meets the standard. Courts look for changes that have had, or could have, a real effect on your child’s well-being. These are the most common qualifying reasons:
- Relocation: A parent moves far enough away to make the current parenting schedule unworkable.
- Safety concerns: Evidence of domestic violence, substance abuse or neglect.
- Health or capacity issues: A parent develops a condition that limits their ability to care for the child.
- Evolving child needs: A child develops new medical or educational needs the current order cannot address.
A parent’s financial difficulty alone does not qualify if child support adjustments could resolve it.
The established custodial environment standard
If your child has an established custodial environment (ECE) with the other parent, the burden on you rises. An ECE exists when a child has lived with a parent long enough to rely on them for stability and daily care. You must then prove by clear and convincing evidence that a modification serves the child’s best interests. Without an ECE, a preponderance of evidence is enough.
How to file a modification motion
Even if both parents agree to a new arrangement, the current order stays in effect until a judge signs a new one. You must file a Motion Regarding Custody through the Michigan One Court of Justice website. The court charges a filing fee, but you may qualify for a waiver if you cannot afford it.
Next steps in your custody case
Modification cases are fact-intensive. An attorney can help you assess whether your situation meets the proper cause or change of circumstances standard.
