A plaintiff is a person or group who brings a legal action against another party in a court of law. This individual or entity claims to have been harmed or wronged and seeks a remedy, which can include monetary compensation or specific actions. The plaintiff initiates the lawsuit by filing a complaint, outlining their grievances and the relief they are seeking. In a legal case, the plaintiff is opposed by the defendant, who responds to the allegations. The role of the plaintiff is crucial in civil cases, such as those involving contract disputes or personal injury, as they set the stage for the legal proceedings.
