Frequently Asked Questions About E-C 3502.3
E-C 3502.3 has a Form Complexity Index of 44 out of 100, placing it in the basic complexity tier. This score is calculated deterministically from the form’s own structure using Instafill’s published Form Complexity Index methodology, so it can be reproduced and independently verified — it is not a subjective estimate.
For E-C 3502.3 specifically, the score reflects 48 fillable fields across 2 pages, grouped into 14 sections, and 10 conditional fields that only apply depending on earlier answers. The number of fields is the largest factor in the base score (weighted 36%), followed by how difficult those fields are to complete based on their type, where free-text and signature fields count for more than simple checkboxes (26%). The number of pages that actually contain fields (15%), the amount of conditional “fill-only-if” logic (16%), and how many sections the form is divided into (7%) account for the rest of the base. On top of that base, the index adds points for tables and repeating lists, bundled instruction pages, and dense page layouts — capturing difficulty the base alone can miss.
In practical terms, a basic score means the form is relatively light, but still needs careful, accurate entry. Instafill removes that effort entirely: our AI reads your information, maps each value to the correct field — including the conditional ones — and completes E-C 3502.3 accurately in under a minute, with every field available for you to review before you download. See exactly how the Form Complexity Index is calculated.
This form is used by a landlord or property owner to start the official court process for evicting a tenant in Illinois. It details the reason for the eviction and what the landlord is requesting from the court, such as possession of the property and past-due rent.
The landlord or property owner, who is referred to as the Plaintiff on the form, must complete and file this document. It is the first step in taking legal action to have a tenant removed from a property.
You should check the 'Unknown Occupants' box if you believe there are people living in the property whose names you don't know. This ensures that the court's eviction order applies to everyone residing at the address, not just the tenants named on the lease.
You are required to attach the 'Demand or Notice' you gave the tenant and the 'Affidavit of Service' that proves it was delivered. If the eviction is for a lease violation, you must also attach a copy of the written lease.
If you cannot provide the required supporting documents, you must complete and attach the 'Affidavit – Supporting Documents Not Attached to Eviction Complaint' form. This affidavit explains to the court why the documents are missing.
Yes, in Section 3, you can check the boxes to demand past due rent, future rent that accrues until the judgment date, and attorney's fees if they are permitted by your lease and local laws.
You will leave the Case Number field blank when you first fill out the form. The Circuit Clerk will assign a Case Number after you have successfully filed the complaint with the court.
In Section 2, check the box that best describes why you are evicting the tenant, such as nonpayment of rent or lease violation. If you select 'lease violation,' you must provide a brief explanation of how the tenant broke the lease terms.
You must file the completed form and all its attachments with the Circuit Clerk's office in the Illinois county where the rental property is located.
The form instructions allow you to type your name in the signature line if you are completing it electronically. If you are filling it out by hand, you must physically sign your name.

Compliance E-C 3502.3
Validation Checks by Instafill.ai
1
Ensures At Least One Defendant is Identified
This check verifies that either at least one full name is entered in the 'Defendants Names' field or the 'Unknown Occupants' checkbox is selected. An eviction complaint must be filed against a specific party or explicitly include unknown parties. Failure to identify a defendant will result in an invalid and unenforceable legal filing.
2
Validates At Least One Reason for Eviction is Selected
This validation ensures that the plaintiff has checked at least one box in section 2 (a-e) to specify the legal grounds for the eviction. A complaint must state a clear cause of action to be legally sufficient. If no reason is provided, the form submission will be rejected as incomplete and lacking a legal basis.
3
Conditional Requirement for Non-Payment of Rent Details
If the box for 'nonpayment of rent' (2a) is checked, this validation confirms that the rent period start date, end date, and the total amount owed are all filled in. These details are essential evidence for the claim and must be provided to substantiate the reason for eviction. Missing this information will prevent the form from being submitted until the fields are completed.
4
Logical Date Order for Non-Payment Period
This check ensures that the 'Nonpayment Rent Period End Date' (2a) is on or after the 'Nonpayment Rent Period Start Date'. An end date that precedes the start date is a logical impossibility and indicates a data entry error. This validation prevents submission of a factually incorrect claim, which could be dismissed by the court.
5
Conditional Requirement for Lease Violation Explanation
When the 'violated the terms of their lease' box (2c) is checked, this validation requires that the corresponding explanation text field is not empty. The court needs to know the specific nature of the alleged violation. An empty explanation field would render the claim vague and legally insufficient, thus blocking form submission.
6
Conditional Requirement for Past Due Rent Amount and Date
If the 'Past due rent' box in section 3 is checked, this validation ensures the 'Past Due Rent Amount Requested' and 'Past Due Rent Owed Through Date' fields are completed. A request for monetary damages must be specific in both amount and the period it covers. Failure to provide these details will result in an incomplete request for damages.
7
Validates Format of All Monetary Fields
This check verifies that all fields intended for dollar amounts, such as 'Unpaid Rent Amount Owed' and 'Past Due Rent Amount Requested', contain only valid numerical currency data (e.g., 1250.00). This ensures data integrity for financial calculations and court judgments. Non-numeric entries will trigger an error message requiring the user to correct the format.
8
Validates Format of All Date Fields
This validation ensures that all date entry fields, such as the non-payment period dates, are entered in a valid and consistent format (e.g., MM/DD/YYYY). Proper date formatting is crucial for legal documents to establish a clear timeline of events. An invalid format will prompt the user for correction before submission.
9
Verifies Attachment of Mandatory Notice or Affidavit
This check confirms that the plaintiff has checked either 'The Demand or Notice' box or the 'Affidavit – Supporting Documents Not Attached' box in section 4. Illinois court rules require proof of notice or an explanation for its absence. This validation enforces a critical procedural step, and failure to select one of these options would make the filing procedurally deficient.
10
Cross-Validates Lease Violation Claim with Lease Attachment
If the reason for eviction is a lease violation (box 2c is checked), this validation checks that the 'The written lease or relevant parts' box in section 4 is also checked. The form instructions mandate attaching the lease for this type of claim. This check ensures the plaintiff provides the necessary supporting evidence for their claim, preventing a filing that is likely to be dismissed for lack of proof.
11
Ensures Completeness of Plaintiff's Signature and Contact Information
This validation verifies that the Plaintiff's Signature, Printed Name, full Street Address, and Telephone number are all provided. This information is required to authenticate the document and provide a means of contact for the court and other parties. Missing any of these fields will prevent the form from being submitted, as they are essential for a valid legal filing.
12
Validates Format of Plaintiff's Email Address
If a value is entered into the 'Signer Email' field, this check ensures it conforms to the standard email address format (e.g., '[email protected]'). Since court documents may be served via email, a valid address is critical for communication. An invalid format would trigger an error, prompting the user to correct the address or leave the field blank.
13
Validates Format of Property ZIP Code
This check ensures the ZIP code entered for the property address is a valid 5-digit number. A correct ZIP code is essential for properly identifying the property's location and jurisdiction. An invalid format will trigger an error and require correction to ensure the address is complete and accurate.
Common Mistakes in Completing E-C 3502.3
Plaintiffs often only list the tenants named on the lease, forgetting about other individuals who may be living in the property. If the 'Unknown Occupants' box is not checked, the court's eviction order may not apply to these unnamed individuals, forcing the landlord to initiate a separate, costly legal process to remove them. To avoid this, always check this box if there is any uncertainty about who is residing at the property, ensuring the sheriff can legally remove everyone.
A common error is omitting the apartment or unit number, or entering an incorrect ZIP code for the property in Section 1. This happens due to haste or oversight. An incomplete address can cause significant delays or even dismissal of the case, as it is essential for properly serving the defendants and for the sheriff to execute the eviction order. Always double-check the full address, including the unit number, to ensure legal documents are delivered correctly and the eviction can be carried out without issue.
When checking box 2c for a lease violation, filers sometimes provide a non-specific reason like 'broke the rules' or 'violated lease.' This is insufficient for a court, which requires a clear, factual basis for the eviction. The consequence is a likely dismissal of the complaint. To prevent this, explicitly state the specific lease clause that was violated and describe the actions taken by the defendant, for example, 'Tenant kept an unauthorized dog in the unit, violating Paragraph 15 of the lease agreement.'
The form explicitly requires attaching the eviction 'Demand or Notice' and the 'Affidavit of Service' (Section 4). Filers, especially those new to the process, may overlook these instructions, assuming the complaint itself is sufficient. Submitting the complaint without these mandatory attachments will almost certainly lead to the case being rejected by the court clerk or dismissed by the judge, wasting time and filing fees. Always use Section 4 as a final checklist before filing.
The instructions for Section 4 clearly state that if the eviction is based on a lease violation (Section 2c), a copy of the lease or its relevant parts must be attached. People often forget this step, weakening their legal argument. Without the lease as evidence, the judge cannot verify the terms the defendant allegedly violated, which can lead to the case being dismissed. AI-powered tools like Instafill.ai can help by creating conditional logic that reminds you to attach the lease if you select 'lease violation' as the reason for eviction.
Filers may enter one amount for unpaid rent in Section 2a and a different amount for 'Past due rent' in Section 3, or the amounts may not match the attached eviction notice. This discrepancy occurs from miscalculation or data entry errors and creates confusion, undermining the plaintiff's credibility and potentially delaying the judgment. To avoid this, carefully calculate all amounts and ensure the figures are consistent across all sections of the form and in all supporting documents. Using a tool like Instafill.ai can help prevent this by cross-validating numerical entries.
When claiming nonpayment of rent (Section 2a), it is crucial to fill in the exact period for which rent is owed and the total amount. People sometimes check the box but forget to enter these specific details, leaving the court without the necessary information to rule on the claim. An incomplete claim for damages can result in the court only granting possession of the property but not a monetary judgment for the rent owed. If the form is a non-fillable PDF, a tool like Instafill.ai can convert it into an interactive version with clearly marked, required fields to prevent such omissions.
In Section 3, plaintiffs may only demand possession and past-due rent, forgetting to check the boxes for 'Future rent due through the date of judgment' or 'Attorneys' fees.' This oversight means they may forfeit their right to collect these additional costs, even if the lease allows for them. To maximize potential recovery, carefully review the lease and Section 3 to ensure you are requesting all legally permissible damages.
Plaintiffs might use nicknames, initials, or misspell the names of the defendants they are trying to evict. This can create a legal loophole, as an eviction order is specific to the names listed on the complaint. A defendant could argue they were not properly named in the suit, causing delays or requiring the plaintiff to refile the case. Always use the full, legal names of all adult tenants as they appear on the lease agreement to ensure the eviction order is enforceable against the correct individuals.
Forgetting to sign the form on page 2 is a simple but critical mistake that immediately invalidates the filing. An unsigned legal document has no legal effect and will be rejected by the court clerk. This error often happens when filers are in a hurry and focus only on the factual sections. To avoid this, make the signature line the very last item you check before making copies or filing. AI form-filling tools like Instafill.ai can prompt for a digital signature, ensuring this crucial step is not missed.
