Frequently Asked Questions About Form ATJ 1403.6
This form is used in Illinois Circuit Courts by a Defendant or Respondent to formally reply to the allegations made in a Complaint or Petition that was filed against them. It allows you to state whether you agree with, disagree with, or lack knowledge about each claim.
You need to fill out this form if you have been named as a Defendant or Respondent in a lawsuit in an Illinois Circuit Court and have been served with a Complaint or Petition. This is your official response to the case initiated by the Plaintiff or Petitioner.
All case information, including the county, Plaintiff/Petitioner and Defendant/Respondent names, and the Case Number, can be found on the Summons and Complaint or Petition you received. It is crucial to copy this information exactly as it appears on those documents.
Choose 'Admit' if you agree the entire statement in the paragraph is true. Select 'Deny' if you disagree with any part of the statement. Use 'Do Not Know' only if you genuinely lack enough information to truthfully confirm or deny the statement.
No, you do not explain your reasoning in this section. The form is only for admitting, denying, or stating you don't know; you will have the opportunity to present your evidence and explanations later in the case.
If the Complaint lacks numbered paragraphs, you should check box 3B. This option allows you to deny everything in the Complaint except for specific statements that you write down as either 'admit' or 'do not know'.
An Affirmative Defense is a legal reason why the other party should not win, even if their claims are true. A Counterclaim is your own separate legal claim against the person who sued you, which must be related to the original case and filed at the same time as your Answer.
After completing your Answer, you must file it with the Circuit Clerk’s office in the county where the case is taking place. Then, you must send a copy to the other party (or their lawyer) as detailed in the 'Proof of Delivery' section.
The 'Proof of Delivery' section is your sworn statement to the court that you have sent a copy of your Answer to the other party. You must specify how (e.g., email, e-filing system, mail) and when you sent the documents.
If you need more space, you can use the 'Additional Paragraphs for Answer or Response' form. Remember to check the box on the main form indicating that you have attached this additional document.
Yes, services like Instafill.ai use AI to help you fill out forms accurately and save time. These tools can auto-fill fields and make the process of completing legal documents faster and easier.

Validation Checks by Instafill.ai
1
Ensures Case Number is Present and Consistent
This check verifies that the 'Case Number' field is filled in on the first page and that the same value is populated in the Case Number fields in the headers of subsequent pages. The case number is the primary identifier for a court case, and inconsistencies can lead to the document being misfiled or rejected by the clerk. If the numbers do not match, the user should be alerted to correct the discrepancy before submission.
2
Verifies Filer's Role is Selected
In Section 1.B, the user must identify their role by checking either 'Plaintiff/Petitioner' or 'Defendant/Respondent'. This validation ensures that one, and only one, of these boxes is checked. This information is fundamental to understanding the context of the response, and failure to select a role makes the filing ambiguous and potentially invalid.
3
Enforces Mutually Exclusive Response Sections (3.A vs. 3.B)
The form provides two distinct methods for responding in Section 3: checkbox 'A' for complaints with numbered paragraphs and checkbox 'B' for those without. This validation ensures that the user fills out the fields associated with only one of these sections. Allowing both to be filled would create a confusing and legally contradictory document, so the system should prevent data entry in one section if the other is chosen.
4
Validates Completeness of Paragraph Responses in Section 3.A
For each row in Section 3.A where a 'Paragraph Number' is entered, this check confirms that exactly one of the corresponding 'Admit', 'Deny', or 'Do Not Know' checkboxes is selected. This is crucial for ensuring a clear and unambiguous response to each specific allegation in the original complaint. An incomplete or multi-selected row would be legally insufficient and require clarification.
5
Validates Signature Block Logic (Self-Represented vs. Lawyer)
This check ensures that if the 'I am completing this form for myself' box is checked, the individual's contact information is provided, and the lawyer fields are disabled or ignored. Conversely, if the 'I am a lawyer...' box is checked, it validates that the Lawyer Name, Attorney Number, and Law Firm fields are completed. This prevents incomplete or conflicting filer identification, which is essential for proper communication and legal standing.
6
Ensures Proof of Delivery Method and Details are Provided
In the 'Proof of Delivery' section, the user must select a delivery method (Email, EFSP, or Mail/Hand Delivery). This validation confirms that at least one method is chosen and that the corresponding detail field (e.g., the email address for email delivery, or the mailing address) is filled out. Failure to provide this constitutes defective service, which can invalidate the filing and have serious legal consequences.
7
Validates Email Address Format
This check applies to all email input fields on the form, including the filer's, lawyer's, and recipient's email addresses. It verifies that the entry conforms to a standard email format (e.g., '[email protected]'). This is critical for ensuring that electronic service and court communications are sent to a valid destination, as required by court rules for e-filing.
8
Requires Essential Case-Identifying Information
This validation ensures that the 'County', 'Plaintiff/Petitioner', and 'Case Number' fields at the top of the form are not left blank. This information is the absolute minimum required for the court clerk to identify the case and docket the document correctly. A submission lacking this information would be rejected outright.
9
Validates Delivery Date and Time Format
The 'Proof of Delivery' section requires a 'Date' and 'Time' of service. This check validates that the date is in a valid format (e.g., MM/DD/YYYY) and that the time is also in a valid format, including AM/PM. This information creates the official record of when the document was sent, which is legally significant for deadlines and response times.
10
Conditional Requirement for Attorney Number
This validation is triggered when the 'I am a lawyer...' checkbox is selected in the signature block. It ensures that the 'Attorney Number' field is filled with a value. The attorney number is a unique identifier required by the state bar and the court system to verify the lawyer's credentials and good standing, making it a mandatory piece of information for legal representation.
11
Ensures Signature and Printed Name are Present
This check verifies that both the 'Signature /s/' and 'Print Name' fields in the main signature block are filled out. Under court rules, a signature certifies the truthfulness of the document's contents and is a strict requirement for a valid filing. An unsigned document has no legal effect and will be rejected.
12
Validates Conditional Mail Delivery Location
If the user checks the 'Mail or third-party carrier' box in the Proof of Delivery section, this validation ensures the 'Location of mailbox or third-party carrier' field is completed. This detail provides specific evidence of the act of mailing, which can be important if the service of the document is ever challenged. The form requires this detail to substantiate the chosen delivery method.
