The plaintiff’s petition or complaint is the document filed with the court and delivered to the defendant (served) that initiates a lawsuit and puts the defendant on notice of the plaintiff’s claims against the defendant and the relief the plaintiff is asking the court to award (usually money or injunctive relief).
In Illinois, the plaintiff's petition or complaint is the initial legal document filed in a civil court to start a lawsuit. This document outlines the plaintiff's allegations and the specific relief or damages sought. According to Illinois law, the complaint must provide sufficient information to inform the defendant of the nature of the claim being made. After filing the complaint with the court, the plaintiff must serve the defendant with a copy of the complaint and a summons, typically through a process server or sheriff. This service of process ensures that the defendant is properly notified of the lawsuit and has the opportunity to respond. The defendant is then required to answer the complaint, usually within 30 days, to avoid a default judgment. The Illinois Code of Civil Procedure governs the format, content, and procedure for filing and serving complaints.
