You've been offered your dream job in Indianapolis. Or maybe you've remarried and want to start fresh in Wisconsin. But there's one major obstacle: your divorce decree requires your children to remain in Illinois, and your ex-spouse is threatening legal action if you move. If you're facing a relocation decision after divorce in Illinois, you're confronting one of the most emotionally charged and legally complex issues in family law.
Relocation cases can resolve in different ways: a parent may be permitted to move with the children, while in other cases a parent must choose between a new opportunity and maintaining primary custody. The difference often comes down to understanding Illinois's specific relocation laws, preparing the right legal strategy, and presenting compelling evidence that the move serves your children's best interests.

Understanding Illinois's 25-Mile Rule
The cornerstone of Illinois relocation law is found in Section 609.2 of the Illinois Marriage and Dissolution of Marriage Act (IMDMA). This statute creates what family lawyers call the "25-mile rule," though the actual distance requirements are more nuanced than that shorthand suggests.
A move is a "relocation" that requires notice and either the other parent's signed agreement or a court order only if it exceeds these distances, measured by an Internet mapping service using surface roads (750 ILCS 5/600(g)):
- From a primary residence in Cook, DuPage, Kane, Lake, McHenry, or Will County: a new Illinois residence more than 25 miles away
- From any other Illinois county: a new Illinois residence more than 50 miles away; and from any county: a new residence outside Illinois more than 25 miles away
The 25-mile out-of-state threshold applies to every Illinois parent, not just those in the Chicago area. A move of 25 miles or less to a new residence outside Illinois is not a relocation under the statute, whether the family lives in Cook County or downstate.
What Counts as "Current Residence"?
The measurement runs from the child's current primary residence, not from the other parent's home or the children's school. The statute measures the distance with an Internet mapping service using surface roads (750 ILCS 5/600(g)), so a straight-line estimate can understate it.
Counties with Different Rules
A move of 25 miles or less across a state line is not a relocation under the statute regardless of which Illinois county the family lives in. A parent in any county who moves more than 25 miles out of state must follow the relocation procedures.
The General Assembly set different in-state thresholds for the six enumerated counties than for the rest of the state, reflecting the density of the Chicago metropolitan area.
Notice Requirements: Getting the Process Right
If your planned move is a relocation under 750 ILCS 5/600(g), you must give the other parent written notice at least 60 days before the move, unless that is impracticable or the court orders otherwise, and file a copy with the circuit clerk (750 ILCS 5/609.2(c)-(d)).
What Must the Notice Include?
Your relocation notice must contain:
- The address of the intended new residence, if known
- The intended moving date
- If the relocation is not permanent, the duration of the relocation
The statute does not prescribe a delivery method, so use one that proves delivery, such as:
- Certified mail with return receipt requested
- Email with read receipt (if your parenting agreement allows electronic service)
- Personal service through a process server (for high-conflict cases)
No Fixed Objection Window
Section 609.2 does not give the other parent a fixed objection deadline. If the other parent signs the notice, the notice is filed with the court, and the parties agree on a modified parenting plan, the relocation may proceed without a hearing. If the other parent does not sign, or the parties cannot agree on a modified plan, the relocating parent must file a petition and obtain a court order before moving.
There is no automatic stay, because absent the other parent's signed agreement the relocating parent has no authority to move in the first place. Timing still matters: if agreement is not reached, the case must be heard and decided before the move, and that can take longer than 60 days.
Emergency Situations
If 60 days' notice is impracticable, written notice must be given at the earliest practicable date, and the court can order otherwise (750 ILCS 5/609.2(d)). Situations where this can come up include:
- Domestic violence or credible threats
- Military deployment orders
- Protection order requirements
- Health emergencies requiring specialized treatment
Can Your Ex Stop You from Moving?
The short answer: possibly, but not automatically. Your ex-spouse cannot unilaterally prevent your relocation simply by objecting. If the other parent objects or does not sign the notice, the parent seeking to move must file a petition, and the court decides under the child's best interests and the factors in 750 ILCS 5/609.2(g).
The Burden of Proof
Section 609.2 does not set different burdens for majority and equal parenting time: either a parent with the majority of parenting time or a parent with equal time may seek to relocate (750 ILCS 5/609.2(b)), and the parent seeking to relocate bears the burden of proving the move is in the child's best interests (In re Marriage of Prusak, 2020 IL App (3d) 190688).

Good Faith Requirements
"Good faith" means you're not moving primarily to frustrate your ex's relationship with the children. Courts examine:
- Your stated reasons for moving
- The timing of the move decision
- Your history of supporting (or undermining) the other parent's relationship
- Whether you've already accepted a job or enrolled children in new schools
Under 750 ILCS 5/609.2(d), the court may treat an unexcused failure to give proper notice as a factor in deciding whether the relocation is in good faith.
Building a Winning Relocation Case
Success in relocation cases requires methodical preparation and compelling evidence. Here's what judges often want to see in these cases:
1. Document Your Legitimate Purpose
Courts recognize numerous valid reasons for relocation:
- Employment opportunities: Show the job offer, salary increase, and career advancement potential
- Educational advancement: Provide acceptance letters, program rankings, and career impact
- Family support: Document how grandparents or siblings will provide childcare and emotional support
- Economic necessity: Demonstrate cost of living differences and financial improvements
- New spouse's career: Show why your spouse cannot relocate their job to Illinois
2. Present a Detailed Parenting Plan
Judges fear relocation will damage the non-moving parent's relationship with the children. Address this proactively with a comprehensive plan showing:
- Proposed parenting time schedule maximizing the other parent's time
- Transportation arrangements and cost-sharing
- Technology use for virtual parenting time (specify platforms and schedules)
- Holiday and summer break allocations
- How you'll maintain the other parent's involvement in decisions
3. Show Community Connections
Demonstrate you've researched the new location thoroughly:
- Schools (provide rankings, special programs, teacher ratios)
- Healthcare providers (especially if children have special needs)
- Extracurricular activities matching current interests
- Religious or cultural communities
- Extended family or support networks
4. Address the Children's Adjustment
Courts worry about disrupting children's stability. Counter this by showing:
- The children's adaptability and past successful transitions
- Counseling or support already arranged
- How you'll maintain connections with Illinois friends
- The new community's advantages for the children's development
5. Financial Impact Analysis
Prepare a detailed comparison showing:
- Current vs. projected household income
- Cost of living differences
- Educational opportunities and costs
- How relocation affects both parents' financial stability
- Any support modification needs (see our article on modifying support after income changes)
Common Mistakes That Destroy Relocation Cases
In relocation disputes, parents sometimes inadvertently undermine otherwise strong cases through these preventable errors:
1. Moving Without Permission
The fastest way to lose a relocation case is to move first and ask permission later. Moving without the other parent's signed notice or a court order violates the statute, can lead to contempt or an order to return, and can be weighed against you on good faith (750 ILCS 5/609.2(d)). A parent who moves unilaterally may lose primary custody entirely.
2. Hiding Your Plans
Secretly planning a move—researching schools, accepting job offers, or signing leases before notifying your ex—undermines your credibility. Courts have broad discovery powers, and hidden preparations often surface. In the age of digital evidence, assume every email and text will be discovered. Protect your digital privacy during divorce proceedings while still maintaining transparency about relocation plans.
3. Making It About Your Ex
Focusing on your ex-spouse's failings rather than your children's best interests is a losing strategy. Judges don't care that your ex is difficult—they care about maintaining both parents' relationships with the children.
4. Inflexible Proposals
Presenting a "take it or leave it" relocation plan signals bad faith. Show willingness to compromise on:
- Moving date flexibility
- Extra parenting time before/after the move
- Transportation responsibilities
- Communication schedules
- Financial adjustments
5. Ignoring the GAL
If the court appoints a guardian ad litem, the court will weigh the GAL's recommendation, and failing to cooperate with the investigation can seriously hurt your case. For more on working effectively with GALs, see our comprehensive guide on Guardian ad Litems in Illinois cases.
6. Weak Economic Arguments
"I can make more money there" isn't enough. You need to show:
- Why similar opportunities don't exist locally
- How the economic gain benefits the children specifically
- That you've genuinely explored local alternatives
- The move isn't speculative or uncertain
The Role of Guardian ad Litems in Relocation
In contested relocation cases, courts frequently appoint a Guardian ad Litem (GAL) to investigate and make recommendations. The GAL's role in relocation cases differs from typical custody disputes in several important ways.
What the GAL Investigates
The GAL will thoroughly examine:
- Each parent's motives for supporting or opposing relocation
- The children's relationships with both parents
- The impact on the children's education and activities
- The feasibility of maintaining meaningful contact
- The children's preferences (if age-appropriate)
- The relative advantages of each location
Influencing the GAL's Recommendation
GALs in relocation cases often focus heavily on practical logistics. Provide the GAL with:
- Detailed travel schedules with specific flight options
- Cost analyses for transportation
- Virtual visitation technology demonstrations
- References from teachers, coaches, and counselors
- Evidence of your history facilitating the other parent's relationship
When GALs Oppose Relocation
GALs typically recommend against relocation when:
- The children have special needs requiring established providers
- Teenagers are close to graduation
- The non-moving parent is highly involved in daily activities
- The distance makes regular parenting time impractical
- The moving parent has previously interfered with parenting time
Understanding these factors helps you address concerns proactively in your GAL interviews and documentation.
Temporary Relocation vs. Permanent Moves
Not all relocations are permanent. A temporary relocation goes through the same notice and best-interest process, but the notice must state how long it will last (750 ILCS 5/609.2(d)(3)), and a defined return date can matter to the court.
What Qualifies as Temporary?
Courts generally consider relocations temporary if they're:
- For a defined period (e.g., 2-year graduate program)
- Related to military deployment
- For medical treatment with expected return
- Employment assignments with clear end dates
Legal Standards for Temporary Moves
A temporary relocation may be easier to justify because:
- The disruption to parenting time is limited
- Children maintain their "home base" in Illinois
- Return plans provide certainty
- The purpose is usually compelling (education, military service)
However, you still must follow notice requirements and may need court approval if the other parent objects.
Practical Considerations
When seeking temporary relocation:
- Specify exact departure and return dates
- Maintain the Illinois residence if possible
- Propose makeup parenting time upon return
- Consider school year vs. summer timing
- Address holiday allocations during absence
Interstate Move Considerations
Moving across state lines adds layers of complexity beyond Illinois law. Interstate relocations add jurisdiction and enforcement questions that don't arise in intrastate moves.
The UCCJEA Factor
The Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA) governs which state has jurisdiction over custody matters. Key points:
- The Illinois court that entered the custody order generally keeps exclusive, continuing jurisdiction until a court finds that the child and parents no longer have a significant connection with Illinois, or that none of them still lives here (750 ILCS 36/202)
- Emergency jurisdiction exceptions exist for safety issues
- You cannot forum-shop for more favorable laws
- Intentionally violating a custody order by concealing, detaining, or removing the child from the court's jurisdiction is child abduction under Illinois law (720 ILCS 5/10-5(b)(1))
Enforcing Illinois Orders Out of State
Other states must give full faith and credit to a valid Illinois custody determination under the federal Parental Kidnapping Prevention Act (28 U.S.C. § 1738A), and the UCCJEA provides registration and enforcement procedures. However, practical enforcement requires:
- Registering the order in your new state
- Understanding local enforcement procedures
- Potentially hiring counsel in both states
- Coordinating with local law enforcement
Tax and Support Implications
Interstate moves affect various financial obligations:
- State income tax differences change net income
- Support calculations may need adjustment
- College savings plan considerations
- Health insurance network coverage
When Courts Deny Relocation
Understanding why courts deny relocation helps you avoid these pitfalls. Courts weighing the 609.2(g) factors are less likely to approve relocation in circumstances like these:
Bad Faith Motivations
Courts see through pretextual reasons for moving. Red flags include:
- Moving to be with someone you just met
- Relocating immediately after adverse custody rulings
- Choosing locations that maximize distance from your ex
- Refusing reasonable local alternatives
Inadequate Planning
Speculative moves rarely succeed. Courts deny relocations based on:
- "Hoping to find" employment
- Uncertain living arrangements
- Incomplete school research
- No concrete parenting time proposals
Children's Opposition
While not determinative, the child's wishes are a statutory factor, weighed according to the child's maturity and ability to express reasoned and independent preferences (750 ILCS 5/609.2(g)(8)). Courts may consider:
- Teenagers' established social networks
- Academic or athletic commitments
- Consistent preferences over time
- Reasons beyond parental influence
Historical Interference
Parents who've previously violated court orders or interfered with parenting time face uphill battles. Courts examine:
- Compliance with current orders
- Communication patterns with your ex
- Willingness to facilitate relationships
- Past relocation attempts
For a comprehensive understanding of how Illinois courts analyze these factors, consult our Illinois divorce case law database.
Modifying Support After Relocation
Successful relocation often triggers support modifications. Both parents should anticipate financial adjustments based on the new circumstances.
Child Support Considerations
Relocation affects support calculations through:
- Changed income if new employment
- Different tax obligations between states
- Altered parenting time percentages
- Transportation cost allocations
- Educational expense differences
Allocation of Transportation Costs
Courts allocating transportation costs may consider:
- Who initiated the relocation
- Relative incomes
- Practical logistics (who drives/flies)
- Children's ages and preferences
Common arrangements include:
- Moving parent pays all transportation
- Costs split proportional to income
- Each parent pays for their pickup
- Annual reassessment provisions
Modification Timing
Strategic timing of modification requests matters:
- File concurrently with relocation approval
- Address temporary orders during transition
- Build in automatic review dates
- Document actual vs. projected costs
When to Hire an Attorney
While some family law matters can be handled pro se, relocation cases demand professional representation. The complexity of statutory requirements, evidentiary standards, and strategic considerations make attorney involvement crucial.
Signs You Need Immediate Legal Help
Contact an attorney immediately if:
- Your ex has already hired counsel
- You're facing tight deadlines (job start dates, school enrollment)
- The other parent is alleging domestic violence
- Interstate or international moves are involved
- High conflict already exists
What Your Attorney Will Do
Relocation counsel will:
- Analyze your specific facts against current case law
- Develop compelling good faith arguments
- Prepare comprehensive parenting proposals
- Handle GAL interactions strategically
- Navigate evidentiary requirements
- Negotiate creative solutions
Cost-Benefit Analysis
Contested relocation cases can be expensive, depending on complexity and conflict level. However, consider the lifetime impact:
- Career advancement opportunities
- Children's educational advantages
- Extended family support
- Quality of life improvements
The investment in skilled representation often pays dividends through successful outcomes and well-crafted agreements that prevent future litigation.
Frequently Asked Questions
How far can I move with my children without court permission in Illinois?
From a primary residence in Cook, DuPage, Kane, Lake, McHenry, or Will County, you can move up to 25 miles within Illinois; from any other Illinois county, up to 50 miles within Illinois; and from anywhere, up to 25 miles outside Illinois, measured by an Internet mapping service using surface roads (750 ILCS 5/600(g)). A longer move requires written notice and either the other parent's signed agreement or a court order (750 ILCS 5/609.2).
Can my ex stop me from moving with our children?
Your ex cannot block a move alone, but if they object or do not sign your notice, you must file a petition, and the court decides based on the child's best interests and the factors in 750 ILCS 5/609.2(g). The same process applies whether you have majority or equal parenting time, and the parent seeking to move bears the burden of proof.
What's the 25-mile rule in Illinois relocation cases?
The "25-mile rule" is shorthand for the relocation definition in 750 ILCS 5/600(g), which Section 609.2 applies: more than 25 miles within Illinois from Cook, DuPage, Kane, Lake, McHenry, or Will County; more than 50 miles within Illinois from other counties; and more than 25 miles outside Illinois from any county.
What happens if I move without following proper procedures?
Moving without proper notice or court approval can result in contempt of court charges, orders to return the children immediately, loss of primary custody, financial sanctions, and damage to your credibility in future proceedings. Always follow statutory requirements.
How much notice must I give before relocating?
You must provide written notice to your ex-spouse at least 60 days before the intended relocation date. The notice must state the intended move date, the new address if known, and how long the relocation will last if it is not permanent, and a copy must be filed with the circuit clerk (750 ILCS 5/609.2(c)-(d)).
What if my relocation is temporary?
Temporary relocations (for education, military deployment, or defined work assignments) use the same notice process, and the notice must state how long the relocation will last (750 ILCS 5/609.2(d)(3)). Courts are more likely to approve temporary moves with clear return dates and maintained Illinois connections.

Can I move out of state with my child after divorce in Illinois?
Only with the other parent's written consent or court approval under 750 ILCS 5/609.2. You must provide 60 days notice and a detailed relocation notice. Courts consider the child's best interests, reason for the move, and impact on the parent-child relationship.
What happens if I move without permission?
Severe consequences: contempt of court, immediate return of the child, loss of decision-making authority, reduced parenting time, attorney fee sanctions, and potential criminal charges for custodial interference under 720 ILCS 5/10-5.
How do Illinois courts decide relocation cases?
750 ILCS 5/609.2(g) requires analysis of: child's wishes, reason for move, quality of life improvements, relocating parent's motives, feasibility of preserving parent-child relationships, and any prior agreement regarding relocation.
What distance requires relocation notice in Illinois?
Moves more than 25 miles from the current residence if within Illinois, or any move out of state, require formal relocation notice under 750 ILCS 5/609.2. Shorter moves may still trigger modification proceedings if they substantially affect parenting time.
