A Westmont Divorce Is Shaped Before Anyone Reaches Wheaton
Every divorce filed from Westmont is heard at the DuPage County Judicial Center in Wheaton, and by the time a case gets there, most of what will determine the outcome has already happened. The route was chosen. The financial record was either built properly or it was not. The tone between two people who still have to raise children together was either preserved or spent. Those decisions get made in the first few weeks, usually before a petition exists, and usually without anyone explaining that they are decisions at all.
Kulerski & Cornelison is a divorce and family law firm in Oakbrook Terrace, a few minutes up Route 83 from Westmont. Kari L. Cornelison has practiced Illinois family law since 1996. She is a court-certified mediator and a trained collaborative lawyer, and she is also an experienced litigator. That combination is the point. Knowing what a contested case genuinely costs is what turns avoiding one into a strategy rather than a slogan.
Why Westmont Clients Work With Us
Plenty of DuPage firms file first and negotiate later. That order is expensive, and the tone it sets is difficult to undo. Here the first conversation is about which process fits your situation, not about what to put in the petition. You also work with the attorney who took your first call rather than whoever has capacity that month, which matters more than it sounds when you are eight months into a parenting negotiation and the person across the table needs to remember what you said in month one.
Clients tend to come back to the same few things:
How Illinois Family Law Applies to a Westmont 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 creates an irrebuttable presumption that the requirement is satisfied. Cases from Westmont are filed in the Eighteenth Judicial Circuit and heard in Wheaton. A few statutory provisions do most of the work in an ordinary case, and knowing them 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 no longer uses custody language. A parenting plan is due within 120 days of service, and decision-making on education, healthcare, religion and activities can be split.
Child Support
Calculated on the income shares model in 750 ILCS 5/505, which uses both parents net incomes and the overnight count. Once each parent has at least 146 overnights, a shared parenting adjustment applies.
Spousal Maintenance
Governed by 750 ILCS 5/504. A guideline formula applies to most couples below the combined income threshold, and a court can depart from it only for reasons it has to put on the record.
Property Division
Illinois divides marital property equitably, which is not the same as equally. What each spouse brought in, what the marriage produced, and what each will realistically earn afterward all carry weight.
Relocation and Modifications
A move of more than 25 miles from a DuPage residence needs notice and, if contested, court approval under 750 ILCS 5/609.2. Existing orders change only on a substantial change in circumstances.
Understanding this at the start is worth real money. A large share of the expensive disputes we see began as a misunderstanding about what the law actually required.
What We Handle for Westmont 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 how this firm normally works rather than alternatives held in reserve for clients who think to ask. When a case does have to be litigated, because the other side leaves no realistic alternative, 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 Westmont Families Bring Us
The presenting problem is rarely the real one. An argument about a Wednesday overnight is usually an argument about something else, and naming that early tends to shorten the case considerably.
A parenting schedule that works on paper and not in practice
Support built on income nobody has actually verified
A home worth far more now than when it was bought
A spouse who will not engage with the process at all
An order that a job or a move has made unworkable
Each of these has a legal answer and a practical one, and they are not always the same. Part of the work is telling you which is which.
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 outset, 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 likely to do. The second answer shapes everything that follows.
We choose 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. We say so first.
We build the financial record before negotiating
An agreement resting on numbers that later turn out to be wrong was never really an agreement.
We document it so it holds
The marital settlement agreement and the parenting plan, written to be followed years later by two people who no longer talk, without a lawyer needed to interpret them.
We will also tell you when your position will not hold up. Early, in a meeting that costs a fraction of what a failed hearing would.
Serving Westmont and the Surrounding Communities
Our office is in Oakbrook Terrace, a short drive north of Westmont. We represent clients throughout DuPage County and into Cook County, including Downers Grove, Hinsdale, Clarendon Hills, Oak Brook, Wheaton, Naperville, Lisle, Darien, Willowbrook, Woodridge, Lombard, Villa Park and Elmhurst. Every DuPage case runs through the same courthouse in Wheaton, so where you live inside the county affects the drive far more than it affects 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 an experienced 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 settle cases tend to overvalue settlement, and lawyers who only try cases tend to undervalue it. Having done both, she can tell a Westmont client what a judge in Wheaton is realistically likely to do with a given set of facts, and then let that client decide whether the offer on the table beats it. Her practice is built around keeping families out of court wherever that is possible, not because litigation never has a place, but because she has seen 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.”
