In Illinois, you have 30 days after you are served with the summons and complaint to file an answer or otherwise respond. That deadline comes from Illinois Supreme Court Rule 101(d), and the clock starts the day after service, not the day the lawsuit was filed.1Illinois Courts. Illinois Supreme Court Rule 101 Miss it, and the plaintiff can ask the court to enter a default judgment against you without hearing your side.
When the 30 Days Starts and When It Shifts
The standard rule is straightforward: 30 days from service. What counts as service matters, though, because different service methods reset the clock differently.
If you were served outside Illinois under Section 2-208 of the Code of Civil Procedure, no default can be entered until at least 30 days after service, and the return date on the summons may be set anywhere from 40 to 60 days after issuance.2Illinois General Assembly. Illinois Code 735 ILCS 5 – Code of Civil Procedure – Section: Personal Service Outside State If you waive formal service under Rule 101, you get at least 60 days from the date the waiver request was sent, or 90 days if you are outside the United States.3Illinois Courts. Amended Rule 101 – Summons and Original Process – Form and Issuance
Otherwise, assume 30 days, count from the day after you were served, and work backward from there.
What Counts as a Timely Response
Filing an answer is not the only way to respond. You can also file a motion to dismiss or another responsive pleading within the 30-day window, and doing so preserves your rights while the court considers the motion. Illinois recognizes two main dismissal motions: a Section 2-615 motion, which argues that the complaint fails to state a valid legal claim even if everything in it is true,4Illinois General Assembly. Illinois Code 735 ILCS 5/2-615 – Motions With Respect to Pleadings and a Section 2-619 motion, which argues that some outside fact, such as an expired statute of limitations or a prior release, defeats the claim.5Illinois General Assembly. Illinois Code 735 ILCS 5/2-619 – Involuntary Dismissal They can be combined in a single filing under Section 2-619.1.6Justia Law. Illinois Code Chapter 735 Act 5 Article II – Civil Practice
What matters for the deadline is that something gets filed in court before day 30. Silence is what triggers default.
What Your Answer Must Contain
If you do file an answer, it isn’t a letter or a general denial. Section 2-610 requires you to walk through the complaint paragraph by paragraph and explicitly admit, deny, or state that you lack enough knowledge to form a belief about each allegation.7Illinois General Assembly. Illinois Code 735 ILCS 5 – Code of Civil Procedure – Section: Pleadings to Be Specific Any allegation you skip, other than the claimed dollar amount of damages, is treated as admitted. A claim of lack of knowledge has to be backed by a sworn affidavit. A denial that doesn’t fairly meet what the plaintiff actually alleged can be treated as no denial at all.
If the complaint was verified under oath, your answer must also be verified under oath. Section 2-605 requires that once any pleading is verified, every later pleading in the case is verified too, unless the court excuses that requirement.8Illinois General Assembly. Illinois Code 735 ILCS 5/2-605 – Verification by Oath This one catches self-represented defendants who assume a signature is enough.
Affirmative defenses belong in the answer too. Under Section 2-613(d), defenses like release, payment, fraud in the inducement, statute of limitations, and contributory negligence must be pleaded, or you forfeit them.9Illinois General Assembly. Illinois Code 735 ILCS 5/2-613 – Separate Counts and Defenses Anything that would surprise the plaintiff if raised for the first time at trial has to be included in the answer.
Once filed, the answer has to be served on the plaintiff’s attorney (or on the plaintiff directly if unrepresented) under Illinois Supreme Court Rule 11.10Illinois Courts. Illinois Supreme Court Rule 11 – Manner of Serving Documents
Asking the Court for More Time
If 30 days isn’t enough, file a motion asking the court to extend the deadline before it expires. The motion should explain why more time is needed (serious illness, difficulty retaining counsel, complexity of the complaint) and propose a new deadline. Extensions are far more likely to be granted when the request is filed before the original deadline runs out.
Many Illinois attorneys will agree to an extension informally. If the plaintiff’s lawyer consents, an agreed order to the court is usually enough. If the plaintiff objects, the judge will weigh whether the delay would prejudice the other side.
What Happens if You Miss the Deadline
If nothing is filed within 30 days, the plaintiff can ask the court to enter a default. Section 2-1301(d) allows a default for failure to appear or failure to plead, and the court can convert it into a money judgment against you.11Illinois General Assembly. Illinois Code 735 ILCS 5/2-1301 – Default
The financial consequences accumulate. Illinois judgments carry post-judgment interest of 9% per year, though consumer debt judgments of $25,000 or less accrue at 5%.12Illinois General Assembly. Illinois Code 735 ILCS 5/2-1303 – Interest on Judgments A judgment creditor can garnish wages, freeze bank accounts, and place liens on your property. The judgment can also stay on your credit report for seven years or longer.13Consumer Financial Protection Bureau. How Long Does Information Stay on My Credit Report?
Vacating a Default
There is a narrow window to fix a missed deadline. Section 2-1301(e) gives the court discretion to set aside any default before a final judgment is entered, and even after a final default judgment, you can move to vacate within 30 days.11Illinois General Assembly. Illinois Code 735 ILCS 5/2-1301 – Default
After that 30-day vacatur window closes, relief gets much harder. You typically have to file a petition under Section 2-1401 and show both a meritorious defense and diligence once you learned about the default. The legal fees for a contested vacatur can rival or exceed what it would have cost to answer on time.
Electronic Filing Is Mandatory
Illinois requires electronic filing in all civil cases at every level of court, and the rule applies to attorneys and self-represented litigants alike.14Illinois Courts. Mandatory Electronic Filing in Civil Cases Paper filing is not accepted outside of emergencies. That means you need a computer with internet access, an email account you check, the ability to create PDFs, and a registered account on the state’s e-filing system. Set that up early. Technical problems on day 29 rarely earn sympathy.
Two Things to Check Before You Draft an Answer
Whether Service Was Proper
A court cannot exercise power over you unless you received notice that was reasonably designed to inform you of the lawsuit and give you a fair chance to respond. In Illinois, that usually means personal delivery of the summons and complaint to you directly, or to a person at your home or workplace who is old enough and responsible enough to pass it along. Defective service can be raised in a motion to dismiss, and if you win, the plaintiff has to start service over. Courts are practical about minor irregularities, though, and a technical flaw won’t save a defendant who plainly knew about the case.
Whether the Case Belongs in Federal Court
If your case qualifies for federal jurisdiction, you can remove it to the nearest federal district court. The most common basis is diversity: you and the plaintiff are citizens of different states and the amount at stake exceeds $75,000. Cases involving a federal statute can also be removed regardless of the amount.
The removal deadline is also 30 days from when you receive the complaint. If a later amendment first makes the case removable, you get 30 days from that point, but diversity-based removal is barred entirely once more than a year has passed since filing, unless the plaintiff manipulated the case to block removal.15Office of the Law Revision Counsel. 28 USC 1446 – Procedure for Removal of Civil Actions Removal does not rescue a missed state court response deadline. If you plan to remove, do it at the same time you would otherwise respond in state court.
Start the Same Day You Are Served
Thirty days feels like a lot until you try to find an attorney, gather documents, investigate the allegations, register for e-filing, and decide between answering, moving to dismiss, or removing. Whatever path you take, the sooner you start, the more of it stays on your terms. Settlement talks can begin at any point and sometimes resolve the case before any formal response is due; mediation and arbitration are options as well. An attorney familiar with Illinois civil procedure can size up which response protects your rights and fits your facts.
