Most Downers Grove Divorces Never Reach a Contested Hearing
That is not luck. It is the result of decisions made in the first few weeks, usually before either spouse has filed anything, and usually while both are still assuming that a lawyer’s job is to fight. Your case will be heard at the DuPage County Judicial Center in Wheaton whether it settles in four months or drags on for two years. What changes between those two outcomes is how much of your money goes to lawyers instead of to your children.
Kulerski & Cornelison is a divorce and family law firm in Oakbrook Terrace, a short drive from Downers Grove. Kari L. Cornelison has practiced Illinois family law since 1996. She is a court-certified mediator and an experienced trial lawyer, and that combination is deliberate. An attorney who has never tried a case cannot tell you what would really happen if you turned down an offer.
Why Downers Grove Families Work With Us
Downers Grove sends more of our clients than any other community in the county, and most of them arrive through someone who used us before. You deal with Kari from the first call to the final order, not an associate who inherits the file in month three. In family law that continuity matters more than in almost any other practice, because the details that decide a parenting case are the small ones somebody has to remember.
Clients tend to value the same few things:
How Illinois Family Law Actually Works Here
Illinois abolished fault-based divorce in 2016. Irreconcilable differences is now the only ground, and 750 ILCS 5/401(a-5) provides that six months of living separate and apart establishes it conclusively. Downers Grove cases are filed in the Eighteenth Judicial Circuit and heard in Wheaton. The same reform removed the word custody from Illinois statute altogether.
Core principles include:
Parental Responsibilities and Parenting Time
Allocated under 750 ILCS 5/602.5 and 602.7. A parenting plan is due within 120 days of service, and decision-making over education, healthcare, religion and activities can be shared, split, or given to one parent.
Child Support
Calculated on the income shares model in 750 ILCS 5/505, using both parents’ net incomes and the number of overnights each has. A shared parenting adjustment applies once each parent reaches 146 overnights.
Spousal Maintenance (Alimony)
Governed by 750 ILCS 5/504, which sets a guideline formula for couples below the combined income threshold and allows a court to depart from it above that line, or where the guideline result would be unjust.
Property Division
Illinois divides marital property equitably, which does not mean equally. What each spouse brought in, what they earned during the marriage, and what each will need afterwards all feed into the result.
Post-Decree Modifications
An existing order can be changed when there is a substantial change in circumstances. Not every change qualifies, and knowing the difference before filing saves a wasted motion.
Understanding this early is worth real money. Most of the expensive fights we see started as a misunderstanding about what the law actually required.
What We Handle for Downers Grove Clients

The earliest decisions in a divorce shape everything that follows, and most of them get made before anyone files. Call our Oakbrook Terrace office at (630) 928-0600 to talk through where you are.
Common Challenges Downers Grove Families Face
The presenting problem is rarely the real one. A dispute about a Wednesday overnight is usually a dispute about trust, and it will not settle until somebody says so out loud.
A parenting schedule that works on paper and not in practice
Support figures built on income nobody has actually verified
A house worth far more than it was when you bought it
A job change that makes an existing order unworkable
A spouse who will not engage with the process at all
Each of these has a legal answer and a practical one, and they are not always the same. Part of the job is telling you which fights are worth having.
How We Work
The route matters more than the argument. Most of the difference between a four month divorce and a two year one is decided in the first few meetings.
We start with your situation, not your paperwork
What you want the outcome to look like, and what your spouse is realistically likely to do. That second question decides which process is even possible.
We pick a route and price it honestly
Mediation, collaborative, cooperative, one-lawyer or traditional. Each carries a different cost, timeline and demand on you, including the uncomfortable parts.
We build the financial record before negotiating
A settlement resting on numbers that later turn out to be wrong is not a settlement. It is a future court date.
We document it so it holds
The marital settlement agreement and parenting plan, drafted to be followed years later by two people who no longer speak much, then entered at the prove-up in Wheaton.
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.

Meet Attorney Kari L. Cornelison
Kari has practiced family law in the Chicago area since 1996. She is a court-certified mediator, a collaborative law practitioner, and a divorce litigator with substantial trial experience in the DuPage and Cook County courts. That combination is unusual and it is intentional. An attorney who only settles cannot value a case accurately, and one who only litigates reaches for the courtroom first. Having done both, Kari can tell a client what a Wheaton judge would probably do, then leave the decision where it belongs. She built the practice around keeping families out of court, not because litigation is never right, but because she has seen what a contested divorce does to a family that could have avoided one.
What Our Clients Say
“Kari made a stressful process easier to manage. She explained everything clearly and always kept my family’s needs first.”
