What to Do If You've Been Sued in Illinois: A Step-by-Step Guide Under Illinois Law
Being served with a summons and complaint (or petition) can feel like a punch to the gut. Whether it's a debt collection case, breach of contract, personal injury claim, eviction, or any other civil matter in an Illinois circuit court, the most important thing is not to panic, and definitely not to ignore it. Under Illinois law, failing to respond properly and on time can lead to a default judgment, where the plaintiff automatically wins and can begin collecting money, garnishing wages, or placing liens on your property.
This guide outlines the essential first steps based on Illinois Supreme Court Rules and the Code of Civil Procedure. Every case is different, and the specific instructions on your summons control what you must do. This is not legal advice, it is general information only.
1. Read the Documents Carefully (Do This Immediately)
The Summons tells you:
Who is suing you (the plaintiff).
The court and case number.
The deadline and exact instructions (e.g., “file an Appearance and Answer within 30 days after service” or “appear in court on [specific date]”).
The Complaint explains what the plaintiff claims you did (or didn’t do) and what they want (money, eviction, etc.).
Note the date you were served—this starts the clock.
Make copies of everything and keep the originals in a safe place. Start a folder (physical or digital) for all court papers, deadlines, and evidence.
2. Understand Your Deadline – Time Is Critical
In most civil cases (not small claims or eviction), you generally have 30 days after the day you were served to file an Appearance and Answer (Illinois Supreme Court Rule 181).
In small claims (claims of $10,000 or less, excluding costs/interest) or certain money claims up to $50,000, the summons often sets a specific “return date” or first court appearance (usually 40–61 days after the summons was issued).
Eviction cases usually require a court appearance within 7–40 days.
Missing the deadline almost always results in a default judgment against you.
3. File Your Appearance and Answer (or Appear in Court)
Use the Illinois Supreme Court-approved standardized forms (available free at illinoiscourts.gov/forms):
Appearance (Civil) – Tells the court and the plaintiff you are participating in the case.
Answer/Response to Complaint – Go paragraph-by-paragraph and admit, deny, or state you lack sufficient knowledge to admit or deny each allegation. You can also add:
Affirmative defenses (e.g., statute of limitations, payment, improper service).
Counterclaims (claims you have against the plaintiff).
Filing Requirements:
Most cases require e-filing (electronic filing) through an approved provider.
You must also serve a copy on the plaintiff or their attorney (usually electronically).
File a Proof of Delivery form showing you served the other side.
Filing fees apply, but you can request a fee waiver if you qualify (use the Application for Waiver of Court Fees form).
Special Cases:
For small claims ($10,000 or less), you usually do not need to file a formal Answer unless the judge orders one—just appear on the return date.
If you believe the service was improper or the court lacks jurisdiction, file a Motion to Quash Service or Motion to Dismiss before filing an Answer.
4. Consider Hiring an Attorney Right Away
You have the right to represent yourself (pro se), but an experienced attorney can:
Spot strong defenses you might miss.
File motions that could end the case early.
Negotiate a favorable settlement.
Handle discovery, mediation, and trial.
Many cases settle before trial, and having counsel on your side dramatically improves outcomes.
5. Gather Evidence and Prepare
Collect contracts, receipts, emails, photos, witness names—anything that supports your side.
Consider whether mediation or settlement talks make sense.
6. What Happens Next?
After you respond:
The case moves into discovery (exchanging information and evidence).
Possible pretrial conferences, mediation, or motions.
If it doesn’t settle, it goes to trial (bench or jury).
