When business relationships break down, whether over contracts, ownership, competition, or professional misconduct, litigation may be the only way to resolve the dispute. And if a resolution can’t be reached through negotiation or settlement, your case may go to trial.
If you’re a business owner or executive facing trial, it’s natural to feel overwhelmed. Trials are time-consuming, expensive, and high-stakes. But understanding the process and working closely with experienced legal counsel can help you prepare, protect your interests, and increase your chances of success.
Here’s what to expect in a Chicago business trial, from pretrial procedures to verdict and beyond.
1. The Court System: Where Business Cases Are Heard
Most business disputes in Chicago are heard in the Circuit Court of Cook County, specifically in the Law Division for civil cases involving claims over $30,000. More complex or high-dollar business cases may be assigned to the Commercial Calendar Section, which is staffed by judges with experience in business law.
In certain cases, such as those involving parties from different states or federal questions, your case may be heard in the U.S. District Court for the Northern District of Illinois, located in downtown Chicago.
The venue matters because each court has its own local rules, judges, and procedural nuances that can affect how your case proceeds.
2. Pretrial Phase: The Longest Part of the Process
Before you ever step foot in a courtroom for trial, your case will go through an extensive pretrial process. This typically includes:
Pleadings
- Complaint: The plaintiff (the party bringing the lawsuit) files a complaint outlining the claims.
- The complaint has to be served on the Defendant (s).
- Answer and Counterclaims: The defendant responds, potentially raising defenses and their own claims. (If the defendant files a motion to dismiss, it will not have to file an answer until and unless the motion to dismiss is denied.)
Discovery
This phase involves gathering evidence through:
- Interrogatories (written questions)
- Requests for documents
- Depositions (sworn testimony under oath)
- Subpoenas to third parties (for documents or testimony)
Discovery is often the most time-consuming and costly part of litigation but can also be where the case is won or lost.
Motions
Before trial, either side may file motions to:
- Dismiss claims
- Compel discovery
- Exclude evidence
- Obtain summary judgment (asking the court to decide the case without trial)
Many business cases are resolved at this stage without going to trial. Your attorney will advise you whether to push forward or consider settlement based on how discovery unfolds.
3. Trial Preparation: Strategy and Presentation
If the case proceeds to trial, both sides will prepare opening statements, witness lists, trial exhibits, and legal arguments. Your attorney will work with you to:
- Identify key facts and documents
- Prepare witnesses for direct and cross-examination
- Develop a compelling narrative for the judge or jury
- Create demonstrative exhibits, such as charts or timelines
- Prepare objections and trial briefs on complex legal issues
- In jury trials, jury instructions
Business trials often require expert witnesses, such as forensic accountants, valuation specialists, or industry consultants, to testify on financial harm or standard practices.
4. Trial Proceedings: Inside the Courtroom
Many business trials in Chicago are bench trials (decided by a judge), but parties can request a jury trial depending on the claims involved.
Here’s what typically happens in a trial:
In jury trials, the jury is selected
Opening Statements
Each side presents an overview of their case and what they intend to prove.
Witness Testimony
- Direct examination: Your attorney questions your witnesses to tell your side of the story.
- Cross-examination: The opposing attorney challenges your witnesses’ credibility and version of events.
- The process repeats for both sides.
Presentation of Evidence
Documents, emails, contracts, financial records, and other exhibits are introduced to support claims or defenses.
Closing Arguments
Each side summarizes their case and highlights why the judge, or jury should rule in their favor.
The Verdict
- In a bench trial, the judge may issue a ruling immediately or take the matter “under advisement” and issue a written decision later.
- In a jury trial, the jury deliberates privately and delivers a verdict.
Trials can last from a day to several weeks, depending on the complexity of the case.
5. After the Trial: Judgments, Appeals, and Enforcement
Judgment
If you win, the court enters a judgment in your favor, possibly awarding damages, legal fees, or equitable relief (like an injunction). If you lose, the court may enter a judgment against your business, which could lead to collection actions or other remedies.
Post-Trial Motions and Appeals
You may have options to:
- Request a new trial
- Ask the judge to reconsider the decision
- File an appeal to the Illinois Appellate Court or the Seventh Circuit (if federal)
Notices of Appeal
Must be filed quickly—typically within 30 days of the judgment. Your attorney can advise you on whether an appeal is appropriate based on the trial record. Bringing and arguing the issues on appeal takes longer, and the entire process—including getting a decision on appeal—can take longer than one year. Review by a higher court (in Illinois State court, the Illinois Supreme Court or in federal court, the US Supreme Court) generally is extremely difficult because in most cases, these courts only consider the cases that they want to decide. These are generally cases of wide importance rather than issues important only to litigants.
Enforcement
Winning a judgment doesn’t guarantee payment. Your attorney may need to pursue enforcement through:
- Garnishment
- Liens
- Asset seizures
- Contempt proceedings
This phase can involve further legal steps to ensure compliance with the court’s order.
If a judgment for money is rendered against a party, the winner can begin enforcement proceedings against the loser unless the loser posts a bond, generally in the amount of 1.5 times the judgment.
Preparation is your best defense. A business trial in Chicago is a serious, often complex undertaking. It requires thorough preparation, strategic thinking, and an advocate who understands both the legal and business implications of the dispute.
While this describes the procedures that generally apply to trial in state or federal court in Chicago, similar procedures apply to all state courts in Wheaton, Waukegan, Joliet, Springfield, Champaign, and other cities in Illinois, and the cases our firm has handled in New York, Pennsylvania, Ohio, Indiana, Wisconsin, Florida, California, Tennessee, and other states.

Frequently Asked Questions About the Business Litigation Process in Illinois
The duration of a Chicago business trial can vary significantly, from a single day for simple matters to several weeks for complex cases involving numerous witnesses and extensive evidence. The pretrial phase, particularly discovery, is often the longest part of the process and can take many months or even years.
In a bench trial, a judge decides both the facts and the law, ultimately rendering the verdict. In a jury trial, a jury of citizens is responsible for determining the facts of the case based on the evidence presented, while the judge presides over the proceedings and rules on legal issues. Many complex commercial litigation cases are decided in bench trials.
Absolutely. The vast majority of business disputes are resolved before a trial ever begins. Settlement can occur at any stage, from initial negotiations to mediation just before trial. The evidence uncovered during the pretrial discovery process often clarifies the strengths and weaknesses of each side's case, which can motivate a settlement.
