A "Cease and Desist" is a legal document sent to an individual or organization to stop an alleged illegal activity. It typically outlines the specific actions that are being challenged and requests that the recipient halt those actions immediately. This document serves as a formal warning before further legal action may be taken. These letters are commonly used in cases involving intellectual property disputes, harassment, or contract violations. If the recipient does not comply, the sender may pursue legal remedies, which could include filing a lawsuit to enforce their rights and seek damages.
