Can I Move Out of Michigan With My Child? The 100-Mile Rule Explained

Life changes after divorce. A new job opportunity in another state. A desire to be closer to family. A remarriage that involves relocation. These are natural developments — but when you share custody of a child, your ability to move is not unrestricted. Michigan law places significant constraints on a custodial parent's right to relocate with a child, and understanding these constraints before you act is essential to avoiding serious legal consequences.

What Is the 100-Mile Rule?

MCL 722.31 — commonly known as the "100-mile rule" — provides that a parent who has been granted legal residence of a child (the parent with whom the child primarily lives, as established by court order) may not change the child's legal residence to a location that is more than 100 miles from the child's current legal residence without either:

1. The written consent of the other parent, or
2. Court approval following a motion and hearing.

The 100-mile measurement is calculated from the child's current legal residence — not from the other parent's home. And the rule applies in both directions: you need permission whether you are moving from Birmingham to Chicago or from Birmingham to Traverse City.

When Court Permission Is Required

Court permission is required whenever a proposed move would change the child's legal residence by more than 100 miles or to a location outside of Michigan. In practice, the most common scenarios that trigger the rule include:

• Job relocation: A parent receives a job offer or transfer to another state or a distant Michigan city.
• Remarriage: A parent is remarrying a spouse who lives or works in another state.
• Family support: A parent wants to move closer to extended family for help with childcare, housing, or emotional support.
• Educational opportunity: A parent has been accepted to a graduate program or professional school in another state.
• Safety: A parent needs to relocate due to domestic violence or other safety concerns (though emergency mechanisms may apply).

If the other parent consents in writing to the move, court permission is not required — but it is still advisable to file the consent with the court and obtain a modified custody order reflecting the new arrangement. Verbal consent is insufficient and creates risk if the other parent later claims they never agreed.

The Five Statutory Factors for Relocation

When a parent petitions the court for permission to relocate, the court evaluates the request under five factors set forth in MCL 722.31(4):

Factor 1: Whether the legal residence change has the capacity to improve the quality of life for both the relocating parent and the child.

The court looks at whether the move offers genuine improvements — better employment, higher income, stronger family support, improved living conditions, or access to better schools. The improvement must benefit both the parent and the child, not just the parent. A move that advances the parent's career but disrupts the child's schooling and friendships may not satisfy this factor.

Factor 2: The degree to which the proposed move is motivated by a desire to frustrate or defeat the other parent's parenting time.

Courts are alert to moves that appear designed to interfere with the non-moving parent's relationship with the child. If the timing of the move, the chosen destination, or the parent's communications suggest the move is motivated by a desire to limit the other parent's involvement, this factor will weigh heavily against the relocation. Legitimate moves supported by evidence of the specific opportunity — a job offer letter, a graduate school acceptance — are evaluated more favorably.

Factor 3: The degree to which the court is satisfied that there will be a realistic, reasonable, and adequate substitute visitation schedule to preserve and foster the parent-child relationship with the non-moving parent.

This is often the most important factor in practice. The moving parent must propose a revised parenting time schedule that realistically preserves the child's relationship with the other parent. This typically involves extended summer and holiday parenting time, regular video calls, and provisions for transportation costs. The more detailed and workable the proposed schedule, the stronger the moving parent's case.

Factor 4: The extent to which the opposing parent's opposition to the move is motivated by a desire to secure a financial advantage regarding support.

Courts consider whether the non-moving parent's opposition is genuine concern about the parent-child relationship or a strategic attempt to gain leverage in child support negotiations. If the opposing parent has shown little interest in exercising parenting time but suddenly objects when relocation might affect support calculations, this factor works in the moving parent's favor.

Factor 5: Domestic violence, regardless of whether it was directed against or witnessed by the child.

When domestic violence is a factor, the court considers it heavily in the relocation analysis. A parent seeking to relocate to escape domestic violence has a compelling argument, particularly when remaining in proximity to the abusive parent poses ongoing risk. Documented evidence of violence — police reports, PPO filings, medical records — is essential.

Burden of Proof

The burden of proof in a relocation case depends on the existing custody arrangement. If the moving parent has an established custodial environment (the child has primarily lived with that parent for a significant period), the moving parent must prove by a preponderance of the evidence that the move is in the child's best interest. The court also applies the 12 best interest factors under MCL 722.23 in addition to the five relocation-specific factors — making relocation cases among the most evidence-intensive proceedings in family law.

How to Petition for Relocation

If you need to relocate with your child, the process involves several steps:

1. Consult an attorney before making any commitments. Do not sign a lease, accept a job offer with a start date, or enroll your child in a new school before understanding the legal requirements. Courts view premature commitments as attempts to create a fait accompli.
2. File a motion to change legal residence with the court that issued your custody order. The motion should address each of the five statutory factors and include supporting evidence — job offer letters, housing arrangements, proposed school enrollment, and a detailed proposed parenting time schedule.
3. Serve the other parent with the motion and supporting documents. The other parent has the right to respond and to present their own evidence at the hearing.
4. Attend the evidentiary hearing. The court will hear testimony from both parties and may consider evidence from third parties. Be prepared to explain in concrete terms how the move benefits the child and how the revised parenting schedule preserves the child's relationship with the other parent.

How to Oppose a Relocation

If you are the non-moving parent and oppose the relocation, your task is to demonstrate that the move is not in the child's best interest. Effective opposition typically focuses on:

• The strength of the child's current ties: School performance, friendships, extracurricular activities, and community connections that would be disrupted.
• Your active parenting involvement: Evidence that you regularly exercise parenting time, attend school events, participate in medical appointments, and maintain a meaningful relationship that distance would impair.
• Inadequacy of the proposed substitute schedule: Show that the revised parenting time is insufficient to maintain the relationship — particularly for young children who need frequent, consistent contact.
• The moving parent's true motivations: If evidence suggests the move is designed to interfere with your relationship rather than to pursue a legitimate opportunity, present that evidence clearly.

What Happens If You Move Without Permission

Moving without court permission when it is required is among the most damaging things a parent can do in a custody case. The consequences include:

• Court-ordered return: The court can order the immediate return of the child to the original legal residence.
• Change of custody: Courts may change primary custody to the non-moving parent as a direct consequence of the unauthorized move.
• Contempt of court: The moving parent may be found in contempt, which can result in fines and, in extreme cases, jail time.
• Damage to credibility: An unauthorized move signals to the court that the parent prioritizes their own interests over compliance with court orders and the other parent's rights. This credibility damage affects every subsequent custody determination.
• Attorney fee liability: The court may order the moving parent to pay the other parent's attorney fees incurred in bringing the enforcement action.
