Forcible entry and detainer in Illinois is the court process a landlord must use to evict a tenant, set out in 735 ILCS 5/9-101 and the sections that follow. It requires written notice with a specific waiting period, a complaint filed in circuit court, a hearing before a judge, and a court order before anyone leaves. Skipping a step, or getting the notice wrong, usually ends the case. Only the county sheriff can carry out a physical eviction.
Notice Requirements by Ground
Everything in an Illinois eviction starts with the notice. The type of notice, the waiting period, and what it has to say all depend on why the landlord is filing.
Nonpayment of Rent
For unpaid rent, the landlord delivers a written demand giving the tenant at least five days to pay. If the tenant does not pay within that window, the lease can be treated as terminated and the landlord can file without any further notice.1Illinois General Assembly. Illinois Code 735 ILCS 5/9-209 – Demand for Rent The demand has to be in writing and state the amount owed. A verbal request does not satisfy the statute.
Lease Violations Other Than Rent
For any other breach of the lease, the landlord must give at least 10 days’ written notice describing the specific violation and stating that the lease will be terminated. No additional demand for possession is required beyond the 10-day notice.2Illinois General Assembly. Illinois Code 735 ILCS 5/9-210 – Notice to Quit The notice needs to identify the breach clearly enough that the tenant knows exactly what conduct or condition is at issue. Vague descriptions invite dismissal.
Holdover Tenancy
When a tenant stays past the end of the lease with no new agreement, the notice period depends on the rent cycle. Month-to-month tenancies and other terms shorter than a year require 30 days’ written notice. Week-to-week tenancies require seven days.3Illinois General Assembly. Illinois Code 735 ILCS 5/9-207 – Notice to Terminate Tenancy for Less Than a Year The tenant does not have to have done anything wrong. The notice simply ends the tenancy so the landlord can file if the tenant refuses to leave.
Filing the Complaint and Serving the Tenant
Once the notice period runs out without the tenant curing or vacating, the landlord files a complaint in the circuit court for the county where the property sits. The complaint lays out the facts: what the tenant did or failed to do, what notice was given, and what the landlord is asking for, whether that is possession, unpaid rent, or both. Incomplete complaints get dismissed, and the landlord has to start again.
The court issues a summons. Under Illinois Supreme Court Rule 101, the summons in an eviction case must set an appearance date no fewer than 7 and no more than 40 days after it is issued.4Supreme Court of the State of Illinois. Illinois Supreme Court Rule 101 – Summons and Original Process That window gives the tenant time to respond or find a lawyer.
The preferred service is handing the summons to the tenant directly, or leaving it with someone at least 13 years old at the tenant’s home. If personal or abode service fails, the landlord can file an affidavit stating the tenant cannot be found, and the court may allow constructive service. Constructive service requires the sheriff to post three copies of the notice in three public places near the courthouse at least 10 days before the hearing, and to mail a copy to the tenant’s last known address if there is one.5Illinois General Assembly. Illinois Code 735 ILCS 5/9-107 – Constructive Service Courts look closely at whether the landlord genuinely tried personal service first.
The Court Hearing
At the hearing, the landlord has the burden of proving that proper notice was given, that the grounds for eviction are legitimate, and that every procedural step was followed. The judge will typically expect to see the lease, the written notice, proof of how and when the notice was delivered, and either payment records or documentation of the alleged violation. The tenant can challenge any of those elements.
Judges apply the notice and timing rules strictly. A landlord who served a four-day rent demand when five days were required, or who described the wrong violation in the notice, will usually lose. Eviction is procedurally unforgiving on purpose, because the consequence of losing a home is severe.
If the Landlord Wins
A judgment for the landlord can include a possession order, a money judgment, or both.
A possession order gives the tenant a specific date to be out. If the tenant is not gone by that date, only the county sheriff can carry out the eviction. The landlord cannot change the locks, remove belongings, or shut off utilities to force the tenant out. Self-help eviction is illegal in Illinois no matter what the lease says or how clear the court order is. The landlord schedules the eviction through the sheriff’s office and waits for the sheriff to execute.
A money judgment can cover overdue rent, late fees, court costs, and attorney’s fees if the lease allows them. Once entered, it is enforceable against the tenant’s assets through wage garnishment or bank levies, subject to federal limits. Under the Consumer Credit Protection Act, garnishment for consumer debts cannot exceed 25 percent of a worker’s disposable earnings for any pay period, and Illinois law may add further protection. A tenant who cannot pay in full is better off asking about a payment arrangement than ignoring the judgment.
Defenses a Tenant Can Raise
Improper Notice
The most common winning defense is that the landlord failed to follow the notice rules. Notice that was too short, sent to the wrong address, described the wrong violation, or was never properly served can sink the entire case. This is where landlords most often lose evictions they expected to win.
Contesting the Facts
A tenant can also dispute the substance of the claim. Someone accused of nonpayment can produce cancelled checks, bank statements, or receipts showing rent was paid. Someone accused of violating the lease can present evidence that the conduct did not happen, or that the lease did not actually prohibit it. Witness testimony and written communications between the parties often matter here.
The Right to Repair Act
Under the Residential Tenants’ Right to Repair Act, a tenant may deduct repair costs from rent when the landlord fails to fix something required by the lease or by law, as long as the cost does not exceed the lesser of $500 or half the monthly rent. The tenant must first give written notice by certified mail and wait at least 14 days for the repair. The tenant then pays a qualified tradesperson, submits the bill to the landlord, and deducts that amount from rent. A tenant cannot use the Act as a defense to a nonpayment eviction unless every procedural requirement was followed.6Justia. Illinois Code 765 ILCS 742 – Residential Tenants Right to Repair Act Skipping the written notice or hiring an unlicensed contractor undercuts this defense entirely.
Reasonable Accommodation for Disability
Under the Fair Housing Amendments Act, a tenant with a disability can request a reasonable accommodation, meaning a change to a rule or policy that gives the tenant an equal opportunity to keep their housing. If the alleged lease violation is connected to a disability, the tenant can argue the landlord should have granted an accommodation instead of filing to evict. The tenant needs to show a qualifying disability, that the accommodation is necessary because of that disability, and that it is reasonable, meaning it would not impose an undue financial or administrative burden on the landlord.7Administration for Community Living. Using Reasonable Accommodations to Prevent the Eviction of Elderly Tenants with Disabilities The request can be made orally or in writing, and the landlord cannot reject it just because the tenant did not use a specific form.
Sealing an Eviction Record
An eviction filing can follow a tenant for years, even after a dismissal or a tenant win. Illinois law provides two paths to seal the court file. The court has discretion to seal when it finds the landlord’s case was so lacking in factual or legal basis that sealing is clearly in the interests of justice. Sealing is mandatory in some situations, including cases dismissed under Section 9-106 of the Code and evictions brought under the foreclosure-related provisions of Section 9-207.5.8Illinois General Assembly. Illinois Code 735 ILCS 5/9-121 – Sealing of Court File
Sealing is not automatic. A tenant who qualifies has to file a motion asking the court to seal and explain why the case meets the standard. For the discretionary path, a case brought without any real legal basis is the strongest argument. For the mandatory path, the tenant just has to show the case fits one of the qualifying categories.
Effects on Credit and Tenant Screening
An eviction judgment does not appear directly on a credit report from the major bureaus. But if the landlord sends unpaid rent to collections, that collection account can sit on the tenant’s credit report for up to seven years from the date of the first missed payment, making it harder to qualify for loans, credit cards, and future leases.
Tenant screening companies keep their own records. Under federal law, eviction filings can appear on a screening report for up to seven years from the date of filing, even when the tenant was never actually evicted.9Federal Trade Commission. Disputing Errors on Your Tenant Background Check Report Sealed or expunged records should not appear, which is part of why pursuing sealing matters.
If a screening report contains errors, the tenant can dispute the information with the screening company. The company must investigate and report back within 30 days, or 45 days in some cases. If the information is inaccurate, incomplete, or cannot be verified, the company must correct or delete it.9Federal Trade Commission. Disputing Errors on Your Tenant Background Check Report A tenant who was never actually evicted but has a filing showing up should check their screening reports and dispute any entries that are misleading or incomplete.
