A Letter Notice of Litigation (also known as a Litigation Letter) is a legal document sent by a plaintiff to a defendant in order to inform them of an impending lawsuit. The purpose of the letter is to provide the defendant with notice that a lawsuit has been filed, and to inform them of the legal action that will be taken against them. The letter typically outlines the reasons for the lawsuit, the parties involved, and the damages or remedies that may be sought. There are two types of Letter Notice of Litigation: Demand Letter and Summons and Complaint. A Demand Letter is a letter that is sent by the plaintiff to the defendant requesting payment or other relief from the defendant. A Summons and Complaint is a legal document that is sent by the plaintiff to the defendant that outlines the basis of a lawsuit and requests a response from the defendant.
