The AI checks your answers before you download

12 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

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.

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.

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.

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.

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.

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.

What is the purpose of the 'Answer or Response' 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.
Who needs to fill out this form?
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.
Where do I find the Case Number and other case information for the top of the form?
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.
How do I decide whether to check 'Admit,' 'Deny,' or 'Do Not Know' in Section 3?
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.
Do I need to explain why I am denying a statement on this form?
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.
What should I do if the Complaint I'm responding to does not have numbered paragraphs?
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'.
What are 'Affirmative Defenses' and 'Counterclaims' in Section 4?
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.
What do I do after I fill out the form?

What is the 'Proof of Delivery' section for?

What if I run out of space to respond to all the paragraphs on the form?
