Illinois Attachment-Complaint With affidavit and Interrogatories are legal documents used in civil litigation in the state of Illinois. They are used when a plaintiff (the person bringing a lawsuit) is seeking to attach, or seize, the assets of a defendant (the person against whom the lawsuit is brought). The Attachment-Complaint With affidavit and Interrogatories serves as a form of security for the plaintiff in a lawsuit. It allows the plaintiff to attach the defendant's property to the lawsuit until the case is resolved, thereby protecting the plaintiff's interests in the dispute. The Attachment-Complaint With affidavit and Interrogatories contains a sworn statement from the plaintiff attesting to the validity of their claim against the defendant and is signed by an affine (a person who can verify the truth of the statement). The document also includes interrogatories, which are questions posed to the defendant to which they must provide a response. There are two types of Illinois Attachment-Complaint With affidavit and Interrogatories: an Ex Parte Attachment and a Plenary Attachment. In an Ex Parte Attachment, the plaintiff is not required to serve the defendant with notice prior to obtaining the attachment, while in a Plenary Attachment, the defendant must be served notice prior to obtaining the attachment.
