A Cease and Desist Letter is a formal document used to demand that an individual or entity stop engaging in unlawful or harmful activities. It serves as an official warning, outlining the specific actions that must cease immediately to avoid further legal consequences. The letter typically includes details of the misconduct, references to applicable laws or agreements, and a deadline for compliance. It is commonly used in cases of harassment, defamation, copyright infringement, contract violations, and unfair business practices. While not a legally binding document on its own, a cease and desist letter can be an effective tool in resolving disputes before escalating to litigation.
