Illinois Deadlines to Sue Your Landlord: What Renters Need to Know

If you’re renting in Illinois and facing issues with your landlord — like withheld security deposits, unaddressed repairs, or unlawful eviction — it’s crucial to know the legal time limits ("statutes of limitations") for filing a lawsuit. Understanding these deadlines helps you protect your rights and take timely action if things can't be resolved directly with your landlord.

What Is a Statute of Limitations?

The statute of limitations is the official deadline for starting a lawsuit. If you wait too long, you might lose your chance to have a court hear your case, even if your claim is otherwise strong. Different types of disputes have different limits under Illinois law.

Common Landlord-Tenant Disputes and Filing Deadlines in Illinois

Here’s a summary of the most common disputes renters may face, with the applicable deadline to sue in Illinois:

• Security Deposit Disputes: 5 years for written leases, 10 years for oral (unwritten) leases.
• Unlawful Eviction ("Illegal Lockout") or Self-Help Eviction: 5 years.
• Breach of Lease (for unpaid repairs, unreturned property, unfair fees): 10 years (written lease), 5 years (oral lease).
• Property Damage or Personal Injury: 2 years for injury, 5 years for property damage.
• Unpaid Rent Claims (by landlord or renter): 10 years (written), 5 years (oral).

These statutes are set by Illinois law and start from the date when the incident occurred or when the landlord failed to meet their responsibility.^[1]

How to Know When Your Deadline Starts

Your statute of limitations clock usually starts on the day your landlord did (or failed to do) something required by law or the lease. For example, if your security deposit wasn’t returned within 45 days after you moved out, the 5- or 10-year clock starts after that 45 days is up.

Which Court or Tribunal Handles Tenant-Landlord Lawsuits?

Most residential landlord-tenant disputes in Illinois go through Illinois Circuit Courts – Landlord/Tenant Division (sometimes called "Eviction Court"). Your case will be heard in the circuit court serving the county where the property is located.

Forms Renters May Need to Start a Case

• Complaint (Eviction or Other Civil Claim)
  Form Name: "Complaint" (No universal statewide form; many counties offer their own)
  Use: This starts your case in the court. For example, if you believe your security deposit has been unlawfully withheld, you would use a "Complaint" form to sue the landlord.
  Access: Download sample forms and filing instructions on the Clerk of the Circuit Court of Cook County Forms page (choose "Civil" or "Eviction" as appropriate).
• Appearance
  Form Name: "Appearance"
  Use: Lets the court know you are officially participating in the case.
  Access: Find the Appearance form for your county on the Illinois Courts Approved Forms directory.
• Summons
  Form Name: "Summons"
  Use: Officially notifies the landlord of the lawsuit.
  Access: Download from your circuit court’s website, such as the Cook County Clerk site.
