These are letters written by an advocate on a client’s behalf, demanding that the recipient of the letter take or cease a certain action. The purpose of a demand letter is to commence a legal negotiation between opposing parties that will result in dispute resolution. Demand letters usually state the harm the sender has suffered, the relief the sender requests, and may threaten the sender’s intent to accelerate the dispute via a lawsuit. Certain statutes have a mandatory requirement that prospective plaintiffs send a demand letter to prospective defendants before they can make a claim viable under that statute.
