The Delaware Bill of Particulars is a document that provides details about a legal dispute, such as the parties involved, the facts of the dispute, and the relief sought by the plaintiff. It is a formal document that is filed in the Delaware Court of Chancery and must be served on the defendant. There are two types of Delaware Bills of Particulars: Complaint Bills of Particulars and Answer Bills of Particulars. A Complaint Bill of Particulars is filed by the plaintiff and outlines the facts of the case and the relief requested. An Answer Bill of Particulars is filed by the defendant and provides factual information in response to the allegations laid out in the Complaint Bill of Particulars. Both types of Delaware Bill of Particulars must contain a concise statement of the cause of action and the relief sought. They must also include the dates of the events giving rise to the suit, a list of the documents attached to the complaint, and the names of all parties to the action.
