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 Oklahoma, 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 against the defendant, the factual basis for the claims, and the specific relief or damages the plaintiff is seeking. Once the petition is filed with the court, it must be formally delivered to (served on) the defendant. This service of process ensures that the defendant is properly notified of the lawsuit and has an opportunity to respond. The defendant will then have a specific period of time, as dictated by Oklahoma law, to file an answer or other responsive pleading to the plaintiff's petition. Failure to respond in a timely manner can result in a default judgment against the defendant. The petition must comply with the Oklahoma Pleading Code and other relevant court rules regarding format, content, and procedure.
