In Lisle, the School Boundary Decides More Parenting Plans Than People Expect
Most Lisle children attend Lisle District 202, but part of the village feeds Naperville District 203, and two households formed out of one do not always land on the same side of that line. The question tends to surface late, after a schedule has been agreed and somebody has already signed a lease. Where the children go to school sets the weekday exchanges, the drive times, the activities and, often enough, the next argument. Every Lisle divorce is filed in the Eighteenth Judicial Circuit and heard at the DuPage County Judicial Center in Wheaton, roughly ten miles north.
Kulerski & Cornelison is a divorce and family law firm in Oakbrook Terrace, a short drive east of Lisle. Kari L. Cornelison has practiced Illinois family law since 1996. She is a court-certified mediator, a trained collaborative lawyer, and an attorney who has tried contested family cases in DuPage County. Those three usually describe three different lawyers. Having done all of it is what makes it possible to say what staying out of court is actually worth in your case.
Why Lisle Clients Work With Us
This firm was built around resolving cases outside a courtroom. That is the practice itself, not a service line held back for clients who think to ask, and it changes what the first meeting is about.
The same few things come up every time:
How Illinois Family Law Applies to a Lisle Case
Illinois has been a no-fault state since 2016. Irreconcilable differences is the only ground, and under 750 ILCS 5/401(a-5), living separate and apart for six months conclusively establishes it. Cases from Lisle are filed in the Eighteenth Judicial Circuit and heard in Wheaton. A handful of statutes then do most of the work in an ordinary case, and knowing which ones changes what is worth arguing about.
The provisions that decide most cases:
Parental Responsibilities and Parenting Time
Allocated under 750 ILCS 5/602.5 and 602.7. Illinois dropped custody language a decade ago. A parenting plan is due within 120 days of service, and decision-making over education, healthcare, religion and activities can be shared or split by subject.
Child Support
Built on the income shares model in 750 ILCS 5/505, using both parents’ net incomes and the overnight count. A shared parenting adjustment applies once each parent has at least 146 overnights, which is why the schedule and the support number are really one negotiation.
Spousal Maintenance
Governed by 750 ILCS 5/504. Below the combined income threshold a guideline formula applies, and a judge who departs from it has to put the reasons on the record.
Property Division
Marital property is divided equitably under 750 ILCS 5/503, which is not the same standard as equally. What each spouse brought in, what the marriage built, and what each will realistically earn afterward all carry weight.
Relocation and Modifications
A move of more than 25 miles from a DuPage residence requires notice and, if contested, court approval under 750 ILCS 5/609.2. A move across Lisle usually does not reach that threshold, which surprises people on both sides of it.
Understanding this at the outset is worth real money. Most of the expensive disputes we see started as a misunderstanding about what the law actually required.
Income Is Where Lisle Cases Usually Get Complicated
The corporate corridor along I-88 and the BNSF line into the city mean a lot of Lisle households include at least one spouse whose pay is not a flat salary. Bonus, commission, restricted stock, deferred compensation, a quarter that looks nothing like the last one. Both the child support formula in 750 ILCS 5/505 and the maintenance guideline in 750 ILCS 5/504 start from a net income figure somebody has to establish, so that figure is usually the real dispute. Bonus and commission income should be averaged across a period that reflects reality, not whichever single year helps one side. Equity compensation raises a second question before valuation even starts, which is how much of it is marital at all. Business expenses that function as personal income are a recurring argument and a winnable one. Dividing a 401(k) or a pension takes a qualified domestic relations order, a separate document that is easy to forget and expensive to fix later. An agreement built on income nobody verified is not a settlement. It is a post-decree case with a delay built in.
What We Handle for Lisle Clients
We work across the full range of Illinois family law, with the emphasis on resolving matters without a trial wherever the case allows it. Mediation, collaborative divorce, cooperative divorce and one-lawyer divorce are the normal routes here rather than alternatives held in reserve. When a case does have to be litigated, it is handled by an attorney who has actually tried family law cases in DuPage and Cook County.
Where to Start
The earliest choices in a divorce shape everything downstream, and most of them get made before anyone has taken legal advice. A single conversation now is usually the cheapest hour of the whole case.
Common Situations Lisle Families Bring Us
The presenting problem is rarely the actual problem. An argument about a Wednesday overnight is usually an argument about something else, and naming that early tends to shorten the case.
One parent inside the District 202 boundary and one outside it
Support calculated on a salary that ignores half of what the household lived on
A house bought fifteen years ago that is now the largest asset in the marriage
A spouse who will not engage with the process at all
An order that a job change or a new commute has quietly made unworkable
Each one has a legal answer and a practical answer. Part of the job is telling you when those are different.
How We Work
The route matters more than the argument. Most of the gap between a four month divorce and a two year one is decided at the start, not in a courtroom.
We start with your situation, not your paperwork
What you want the result to look like, and what your spouse is realistically going to do. The second answer shapes everything after it.
We pick a route and price it honestly
Mediation, collaborative, cooperative, one-lawyer or traditional. Each asks something different of you, and some of those demands are uncomfortable enough that clients would rather hear about them now than in month six.
We build the financial record before anyone negotiates
Income, accounts, retirement, the house, the debt. Getting this right at the start is what stops a settlement unraveling two years later.
We document it so it holds
The marital settlement agreement and parenting plan, written to be read years from now by two people who no longer talk much, without a lawyer needed to interpret them.
We will also tell you when your position will not survive contact with a judge. Early, in a meeting that costs a fraction of what a failed hearing would.
Serving Lisle and the Surrounding Communities
Our office is in Oakbrook Terrace, a short drive from Lisle. We represent clients throughout DuPage County and into Cook County, including Naperville, Downers Grove, Woodridge, Darien, Westmont, Warrenville, Wheaton, Oak Brook, Hinsdale and Clarendon Hills. Every DuPage case is heard in the same courthouse in Wheaton, so your address inside the county changes the drive far more than it changes the case.
Meet Attorney Kari L. Cornelison
Kari has practiced family law in the Chicago area since 1996. She is a court-certified mediator, a trained collaborative practitioner, and a divorce litigator with years of trial work in the DuPage and Cook County courts behind her. The trial experience is deliberate rather than incidental. Lawyers who only ever settle tend to overvalue settlement, and lawyers who only ever litigate tend to undervalue it. Having done both, she can tell a Lisle client what a judge in Wheaton is likely to do with a particular set of facts, then leave it to the client to decide whether the offer on the table beats that. Her practice is built around keeping families out of court wherever it is possible, not because litigation never has a place, but because she has watched what a contested divorce does to people and to their children.
What Our Clients Say
“Kari made a stressful process easier to manage. She explained everything clearly and always kept my family’s needs first.”
