How to Fight an Illegal Eviction in Illinois

If you're a renter in Illinois facing eviction, it's important to know that not all evictions are lawful. Illinois law sets out strict procedures that landlords must follow before removing a tenant from their home. This page explains what an illegal eviction is, how to recognize your rights, and the steps you can take to protect yourself if you believe your eviction is not legal.

Understanding Illegal Eviction in Illinois

An eviction is considered "illegal" when your landlord tries to remove you from your rental home without following the legal process required by the Illinois Forcible Entry and Detainer Act. This includes:

  • Changing your locks without a court order
  • Turning off utilities to force you out
  • Physically removing your belongings without legal notice

Only a court-ordered eviction, enforced by the sheriff, is legal in Illinois. A landlord cannot evict you by themselves, even if you are behind on rent or there is a lease violation.

Legal Process for Eviction in Illinois

Your landlord must follow these steps to lawfully evict you:

  • Give you proper written notice (such as a 5-day, 10-day, or 30-day notice, depending on the reason)
  • File an eviction lawsuit, called a "Forcible Entry and Detainer" action, with the court
  • Attend a court hearing where you can present your side
  • If the court rules in favor of the landlord, a judge will issue an Eviction Order
  • The sheriff, not the landlord, carries out the actual eviction if you do not move voluntarily

Skipping any part of this process makes the eviction illegal, and you may have the right to stay in your home or even seek damages.

Actions You Can Take to Fight an Illegal Eviction

If you believe your landlord is trying to evict you without going to court, or without a sheriff, you have clear rights and legal steps to protect yourself.

1. Stay Calm and Document Everything

  • Record all communications with your landlord
  • Take photos or videos if locks are changed or utilities are shut off

2. Contact Local Authorities

  • If you are locked out or threatened, contact your local police or sheriff's office. Lockouts are illegal under Illinois law.
  • Show police your lease and explain the situation clearly.

3. File a Complaint with the Circuit Court

You may file a "Verified Petition for Emergency Relief" with your county's Circuit Court if you have been unlawfully locked out. This can ask the court to order your landlord to let you back in.

  • Form: Verified Petition for Emergency Relief (no standardized statewide number; available from your county circuit clerk or local legal aid)
    Example: You arrive home to find your landlord changed the locks without notice. You can use this form to quickly ask a judge for help.

4. Responding to a Formal Eviction Notice

  • If you receive an official court summons (Eviction Summons and Complaint), respond on time—even if you think the eviction is wrongful.
  • Form: Appearance Form (Form: Appearance - CCDO0021)
    Example: The court papers say you have a hearing next week. File an Appearance so your side will be heard.

  • Form: Answer/Response to Eviction Complaint

5. Request a Stay of Eviction Enforcement

  • If the sheriff comes but you believe the process was illegal or unfair, you can ask the court for a "stay," which puts the eviction on hold.
  • Form: Motion to Stay Eviction
    Example: You need more time to find a new place or the landlord didn’t follow the correct procedure.

Renters are never required to leave their home simply because a landlord asks—only the sheriff, with a court order, can carry out an eviction in Illinois.

Your Rights Under Illinois Law

  • You may be entitled to return to your home if illegally locked out
  • You may sue for damages if your belongings are removed, or utilities cut to force you out
  • The sheriff is the only person who may forcibly remove a renter after a court order
  • Retaliation by landlords for exercising your rights is illegal

The Illinois Forcible Entry and Detainer Act is the main legislation protecting renters facing eviction. The courts that handle these disputes are called Illinois Circuit Courts. In Cook County, you can directly visit the Cook County Law Division – Eviction Section for more details.
