Cause of action
To pursue a cause of action, a plaintiff pleads or alleges facts in a complaint, the pleading that starts a lawsuit. A cause of action generally includes both the legal theory (the legal wrong the plaintiff claims to have suffered) and the remedy (the relief a court is asked to grant).  Often the facts or circumstances that allow a person to seek judicial relief may create multiple causes of action. Although it is fairly easy to file a Statement of Claim in most jurisdictions. If it is not done properly, then the filing party may lose his case due to simple technicalities.
