A lawsuit is a legal dispute between two or more parties that is resolved in a court of law. One party, known as the plaintiff, files a complaint against another party, called the defendant, claiming that the defendant has caused harm or violated a legal right. The court then examines the evidence and arguments presented by both sides to reach a decision. Lawsuits can involve various issues, such as contract disputes, personal injury claims, or property disputes. The outcome may result in financial compensation, a change in behavior, or other remedies. If either party disagrees with the court's decision, they may have the option to appeal.
