My Co-Parent Took My Child Out of Illinois | Relocation | LaRocque Law

If the other parent left Illinois with your child, this is not the moment to send angry texts, threaten police action, or wait to “see what happens.”

This is the moment to slow down, preserve evidence, determine whether Illinois has jurisdiction, and decide whether emergency court relief is necessary.

If one parent leaves without notice and the other parent responds by escalating, threatening, or creating more instability, the court now has two problems instead of one. Judges do not love this. Your child won’t either.

A parent leaving the state with a child can feel like everything changed overnight. Sometimes it is a temporary trip. Sometimes it is a real relocation. Sometimes it is a direct violation of a court order. The right response depends on the facts, the existing orders, and how quickly - but rationally - you act.

The goal is not to create more chaos. It's to stabilize the situation for your child and get the right issues in front of the court.

First: Is This an Emergency?

If you believe your child is in immediate danger, call law enforcement and speak with an Illinois family law attorney immediately.

You should also gather any existing court orders, including:

• Allocation judgment;

• Parenting plan;

• Divorce judgment;

• Parentage order;

• Temporary parenting order;

• Order of protection;

• Travel restriction; or

• Any written agreement about parenting time or relocation.

  
  

If there is no immediate safety risk, be careful. Do not retaliate. Do not threaten the other parent. Do not try to take the child back without legal authority.

Do Not Confuse Relocation with a Vacation

Not every trip out of Illinois is a relocation.

A weekend visit, spring break trip, family emergency, or short-term visit with relatives is different from a parent moving the child to another state, enrolling the child in school, changing doctors, refusing to return the child, or announcing that the child now lives somewhere else. Do not confuse the two. Intentionally or not, it will put you in a bad position.

The facts matter.

A court is going to look at whether the move appears temporary or permanent, whether the other parent gave notice, whether the existing parenting schedule is being followed, whether the child’s school or medical care has changed, and whether the other parent is supporting or blocking your contact with the child.

Step 1: Confirm Whether a Court Order Already Exists

Your options depend heavily on whether an Illinois court has already entered an order about parental responsibilities or parenting time.

If there is an existing Illinois order, the other parent may have violated it by leaving the state, refusing to return the child, interfering with parenting time, or relocating without consent or court permission.

If there is no order yet, you may need to file a parentage case, divorce case, petition to allocate parental responsibilities, emergency parenting petition, or other pleading to establish Illinois court authority and request enforceable relief.

Either way, start building the timeline immediately.

Write down:

• The date the child left Illinois;

• When you found out;

• Where the child is, if known;

• What the other parent told you;

• Whether parenting time has been missed;

• Whether the child has been enrolled in school or daycare elsewhere;

• Whether medical providers changed;

• Whether the other parent is allowing calls or FaceTime;

• Any prior threats to leave or withhold the child; and

• Any safety concerns.

Do this while the details are still fresh.

What I Would Want You to Do in the First 24–48 Hours if I Was Your Attorney

If your child was taken out of Illinois or is being withheld in another state, these are the first steps I would want you to take:

1. Compile every court order. Locate your parenting plan, allocation judgment, divorce judgment, temporary order, order of protection, or written parenting agreement.

   
   

2. Save all communications. Preserve texts, emails, voicemails, social media messages, call logs, and screenshots. Do not edit them. Do not delete anything.

   
   

3. Write a timeline. Create a simple timeline of what happened, when the child left, what the other parent said, what you asked for, and what parenting time has been missed.

   
   

4. Do not send emotional messages. Assume every text you send will be attached to a motion. Keep your messages short, calm, and child-focused.

   
   

5. Ask for the child’s location in writing. Ask for the child’s address, school, daycare, medical providers, and a schedule for phone or video contact. Knowing the location or documenting a refusal will put you in a better position.

   
   

6. Continue appropriate communication. Ask for calls, FaceTime, school updates, medical information, and parenting time. Even if you know they won't give it to you, ask.

   
   

7. Call an Illinois family law attorney before taking any major action. Trying to retrieve the child yourself without legal authority can create more problems than it solves.

   
   

Step 2: Understand Illinois’ Relocation Rule

Illinois law does not allow every move with a child to happen automatically.

Under the Illinois Marriage and Dissolution of Marriage Act, a parent who has been allocated a majority of parenting time, or either parent with equal parenting time, may seek to relocate with a child. But when the move qualifies as a “relocation,” the relocating parent must follow the statutory notice and court-approval process.

Under 750 ILCS 5/609.2, the relocating parent generally must give written notice to the other parent and file a copy with the circuit court. The notice usually must be given at least 60 days before the relocation, unless advance notice is impracticable or the court orders otherwise. The notice must include the intended relocation date, the new address if known, and whether the move is temporary or permanent.

If the other parent signs the notice and it is filed with the court, the relocation may proceed without further court action, although the parenting plan or allocation judgment should still be modified to reflect the move.

If the other parent objects, refuses to sign, or the parents cannot agree on a revised parenting schedule, the relocating parent must file a petition asking the court for permission to relocate.

A parent who ignores the notice requirement can create serious problems for themselves. Failure to comply with the statute without good cause may be considered by the court when deciding whether the move was made in good faith. It may also support an award of attorney’s fees and costs caused by the violation.

Step 3: Know What the Court Will Actually Care About

Illinois courts decide relocation disputes based on the child’s best interests.

That does not mean the court only looks at whether the moving parent has a better job, a new relationship, or family support in another state. Those facts may matter, but they do not decide the case by themselves.

What the judge considers in a relocation case isn't a secret. Each specific factor is listed in 750 ILCS 5/609.2. The court will look at:

• Why the parent wants to move;

• Why the other parent objects;

• The history and quality of each parent’s relationship with the child;

• Whether either parent has failed to exercise parenting responsibilities;

• The child’s educational opportunities in Illinois and the proposed new location;

• Extended family in both places;

• The impact of the move on the child;

• Whether a realistic long-distance parenting schedule can be created;

• The child’s wishes, depending on age and maturity;

• Transportation and practical parenting-time arrangements;

• Whether the move will damage the child’s relationship with the parent remaining in Illinois; and

• Any other fact affecting the child’s best interests.

  
  

The court is not just asking whether the move would be good for the parent who wants to leave.

The court is asking whether the move is in the child’s best interests, whether the relationship with both parents can realistically be preserved, and whether the proposed plan is actually workable.

The Case Law, The Practical Version, Not The Law School Version

Illinois relocation law is fact-specific. There is no automatic win just because one parent has a better job offer, family support, or a new opportunity somewhere else.

The major Illinois cases say the same thing in different ways: the child’s best interests control.

In In re Marriage of Eckert, the Illinois Supreme Court made clear that the paramount question is whether relocation is in the child’s best interests. The parent seeking to move has to show that the relocation serves the child, not just the parent.

In In re Marriage of Smith, the Court affirmed denial of a relocation request and emphasized that trial judges receive significant deference because they can hear the testimony, evaluate credibility, and assess the children’s needs firsthand.

In In re Marriage of Collingbourne, the Court approved a relocation and recognized that improving the residential parent’s life can indirectly benefit the child. But the Court still required a full best-interests analysis, including the effect on the child’s relationship with the other parent.

In plain English: relocation cases are not decided by one fact. They are decided by the whole record and its impact on the child.

Evidence That Matters

If the other parent already left Illinois, evidence matters right now.

Helpful evidence may include:

• Prior threats to leave Illinois;

• Texts or emails showing the move was planned;

• Refusal to disclose the child’s location;

• Refusal to allow phone calls or video calls;

• Missed parenting time;

• School enrollment in another state;

• Daycare enrollment in another state;

• Changes to doctors or medical providers;

• Statements that the child now “lives” in the other state;

• Evidence the other parent concealed the move;

• Evidence the move disrupted the child’s school, therapy, medical care, or routine;

• Proof that you asked for contact and were denied; and

• Any evidence showing the child may be at risk.

  
  

Do not rely on memory. Preserve the record.

Screenshots, call logs, emails, school records, travel records, and written timelines can make a difference.

Facts That Can Hurt the Parent Who Left

A parent who leaves Illinois without handling relocation properly may create bad facts for themselves.

Examples include:

• Leaving without notice;

• Refusing to disclose the child’s address;

• Enrolling the child in school without agreement or court permission;

• Blocking calls, FaceTime, or parenting time;

• Ignoring an existing parenting schedule;

• Moving for reasons unrelated to the child;

• Making the move about punishing the other parent;

• Refusing to propose a realistic long-distance parenting plan; or

• Moving again after the first move.

That does not automatically mean the child will be ordered back. But it can matter when the court evaluates good faith, best interests, attorney’s fees, and emergency relief.

Facts That Can Hurt the Parent Who Stayed

The parent who stayed in Illinois can also hurt their position.

Avoid:

• Waiting weeks or months to take action;

• Sending threatening or abusive messages;

• Posting about the dispute online;

• Withholding support;

• Refusing reasonable communication;

• Ignoring existing court orders;

• Trying to physically retrieve the child without legal authority; or

• Making the dispute about punishing the other parent instead of protecting the child.

  
  

The court will look at both parents’ conduct.

If the other parent acted improperly, do not give them new evidence to use against you.

What If the Other Parent Already Left Without Notice?

Depending on the facts, Illinois is most likely the proper state to decide custody and parenting issues, especially if Illinois was the child’s home state.

Under the Uniform Child-Custody Jurisdiction and Enforcement Act ("UCCJEA"), if a child relocates to a new state, the original state usually retains "home state" jurisdiction for six months after the move. The new state can become the home state only after the child has lived there for six consecutive months.

A state without home-state jurisdiction can issue temporary emergency orders if a child is abandoned or needs protection from abuse or mistreatment. That state's jurisdiction would only be temporary.

If Illinois has jurisdiction, you may be able to ask the Illinois court for relief, including:

• An emergency order requiring the child’s return;

• Enforcement of an existing parenting plan or allocation judgment;

• A temporary parenting-time order;

• Disclosure of the child’s address, school, daycare, and medical providers;

• Restrictions on further travel;

• Make-up parenting time;

• Modification of parenting time or parental responsibilities;

• Attorney’s fees and costs caused by the improper move; and

• Other relief tailored to the child’s safety and best interests.

If there are safety concerns, concealment, domestic violence, or risk that the child will be moved again, your attorney may also evaluate emergency remedies under Illinois family law procedures and the UCCJEA.

Should You Call the Police?

Sometimes.

If your child is in immediate danger, call 911.

If there is a court order and the other parent is clearly violating it, law enforcement may be able to help document the violation or enforce certain orders, but it's also very possible that they choose not to.

Many interstate parenting disputes are treated primarily as civil family law matters unless there is a safety issue, concealment, a criminal warrant, or conduct that falls within a criminal statute.

Before making accusations, it is usually better to speak with a family law attorney who can review the existing order and determine whether emergency court action is the better first step.

What Not to Do

If the other parent left Illinois with your child, avoid anything that makes the situation harder to fix.

Do not:

• Threaten the other parent;

• Withhold support;

• Attempt to take the child back without legal authority;

• Post about the dispute online;

• Ignore existing court orders;

• Assume the court will automatically fix it without a proper filing; or

• Wait too long to act.

Delay can matter.

A parent who waits too long may make it easier for the other parent to argue that the child is settling into the new location or that emergency relief is unnecessary.

The Bottom Line:

The first response matters.

In relocation and interstate parenting disputes, delay, emotional texts, and poorly planned filings can make a bad situation harder to fix.

A parent usually cannot make a major relocation decision unilaterally when Illinois law requires notice, agreement, or court permission. Illinois courts focus on the child’s best interests, the reasons for the move, the effect on the child’s relationship with both parents, and whether a practical parenting schedule can preserve those relationships.

If your spouse or co-parent left Illinois with your child, act quickly and strategically.

The goal is not to create more conflict. The goal is to preserve jurisdiction, protect your child’s stability, and get the right issue in front of the court before the situation becomes harder to unwind.

If your child has been taken out of Illinois or is being withheld in another state, do not wait to see if the situation resolves itself. The first filing can shape jurisdiction, emergency relief, and the court’s view of the facts.
