An Illinois Answer/Response to Complaint/Petition is a legal document filed in response to a complaint or petition filed in an Illinois court. It is the defendant's response to the claims made by the plaintiff in the complaint/petition. It must be filed within 28 days from the date of service, and its purpose is to deny, admit, or partially admit the allegations made by the plaintiff. The answer must include a statement of defense, such as lack of jurisdiction, improper service, or statute of limitations. There are four types of Illinois Answer/Response to Complaint/Petition: General Denial Answer, Specific Denial Answer, Partial Admit and Deny Answer, and Admission Answer. A General Denial Answer is an answer that denies all the allegations made in the complaint/petition. A Specific Denial Answer is an answer that denies only certain allegations made in the complaint/petition. A Partial Admit and Deny Answer is an answer that admits some allegations and denies others. An Admission Answer is an answer that admits all the allegations made in the complaint/petition.
