When life changes suddenly, so can the needs of your child. Maybe your ex has moved, your work schedule has shifted, or something has happened that puts your child’s safety or stability at risk. In those moments, parents often need to act quickly, but modifying an existing custody or parenting time order in Michigan requires specific legal steps.

Here’s what to know if you urgently need a post-judgment modification for your custody case, and how to make sure your request is handled correctly and efficiently.

Understanding Post-Judgment Modifications in Michigan

Once a custody or parenting time order is entered, it remains legally binding until a court changes it. That said, Michigan law recognizes that circumstances evolve. Under MCL 722.27(1)(c), a court can “modify or amend its previous judgments or orders for proper cause shown or because of a change in circumstances.”

That means the parent seeking to modify orders must show the judge proper cause or that something significant has changed since the last order was entered. A few examples include:

• A parent relocating or changing work schedules in a way that affects parenting time
• Changes in the child’s needs, health, or schooling
• Substance abuse, neglect, or unsafe behavior by a parent
• Repeated violations of the existing custody order

Acting Quickly When Your Child’s Safety Is at Risk

If your concern involves immediate danger, such as abuse, neglect, or exposure to harmful conditions, you may need to request an emergency motion (also called an ex parte motion) for temporary custody or parenting time modification.

Under Michigan Court Rule 3.207(B), an ex parte motion may be granted without a hearing if you show by specific facts that “immediate and irreparable injury, loss, or damage will result” before the other party can be heard.

If granted, the court can issue a temporary order that protects your child while the full modification hearing is scheduled. These requests require clear, detailed evidence, such as police reports, text messages, medical records, or witness statements.

Proving Proper Cause or a Change in Circumstances

For non-emergency modifications, Michigan courts typically use a two-step process:

1. Establishing proper cause or change in circumstances – You must first convince the court that the change is significant enough to reconsider custody. Minor disagreements or normal life changes typically aren’t enough.

2. Showing that modification serves the child’s best interests – If you pass the first step, the court then reviews the best interests’ factors under MCL 722.23, such as emotional ties, stability, and each parent’s ability to provide care and guidance.

This ensures that any change is truly in the child’s favor and not just convenient for one parent.

Filing a Motion to Modify Custody or Parenting Time

If you need to file a motion to modify custody, parenting time, or child support, contact a Michigan family law attorney. They will help you file the motion in the same court that issued your original judgment. Once filed, the court will schedule a hearing. Depending on your county, a Friend of the Court (FOC) investigator may first review the case and make a recommendation. The FOC is an arm of the circuit court and may investigate the family for the purpose of making recommendations concerning custody and parenting time.

If both parents agree to a change, the process may move quickly. If not, your attorney will present evidence and testimony to demonstrate why modification is necessary and in your child’s best interests.

When Urgency Meets Procedure

Even urgent cases must follow Michigan’s legal process, but the right preparation can help you move faster. A skilled family law attorney can help you:

• Identify whether your situation qualifies as an emergency under Michigan law
• File motions quickly and correctly
• Gather and present the right evidence to support your claim
• Protect your parental rights while prioritizing your child’s safety
