When to Use This Skill

Use this skill when you need to:

  • Draft a cease and desist letter for trademark or copyright infringement
  • Demand that someone stop defamatory statements or contract violations
  • Create a formal written demand before pursuing legal action
  • Document an infringement or violation for legal records

DO NOT use this skill for threats you do not intend to follow through on, personal disputes, or situations requiring immediate legal action. A C&D is a formal demand — consider consulting an attorney before sending. This is a drafting tool, not legal advice.


Core Principle

A CEASE AND DESIST LETTER IS A PROFESSIONAL DEMAND, NOT A THREAT — IT CLEARLY STATES THE VIOLATION, THE REQUIRED ACTION, AND THE CONSEQUENCES OF NON-COMPLIANCE.


Phase 1: Violation Details

Required Inputs

Input What to Ask Default
Your business/name "Who is sending this letter?" No default — must be provided
Violator "Who is the letter addressed to? (name, business, address if known)" No default — must be provided
Violation type "What is the violation? (trademark infringement, copyright infringement, defamation, contract breach, trade secret misuse)" No default — must be provided
Specific conduct "Describe the specific infringing or harmful activity." No default — must be provided
Evidence "What evidence do you have? (URLs, screenshots, documents)" No default — list available evidence
Desired outcome "What do you want them to do? (stop using, remove content, pay damages)" Cease the activity immediately

GATE: Do not proceed without the violation type, specific conduct, and evidence.

Phase 4: Sending and Documentation

## Pre-Send Checklist

- [ ] All facts are accurate and verifiable
- [ ] Evidence is documented (screenshots with dates, URLs saved)
- [ ] Legal basis for the claim is correct
- [ ] Demands are specific and achievable
- [ ] Response deadline is reasonable (14-30 days)

- [ ] Tone is professional — not emotional, threatening, or personal

## Sending Method

Example: Someone Copying Your Course Content

Situation: A competitor copied 3 modules of your online course and is selling them under their own brand.

Letter excerpt: "It has come to our attention that your website [URL] is offering educational content that is substantially similar to copyrighted course modules owned by [Your Business], including [Module 1 Title], [Module 2 Title], and [Module 3 Title]. We have documented these similarities with side-by-side comparisons [attached]. We demand that you remove all infringing content within 14 days and confirm removal in writing."


Anti-Patterns

  • Empty threats — do not threaten legal action you are unwilling or unable to take. It damages credibility.
  • Emotional or aggressive tone — keep it professional. Anger weakens the letter and can undermine your position.
  • Vague demands — "stop copying us" is not specific. State exactly what must be removed, destroyed, or changed.
  • No evidence — document everything before sending. Screenshots, URLs, dates, and comparisons strengthen your position.
  • Sending without legal review for major claims — for significant infringement or high-stakes disputes, have an attorney review or send the letter.

Recovery

  • Recipient ignores the letter: Follow up once, then escalate to legal action or DMCA takedowns. Document the non-response.
  • Recipient responds with counterclaims: Consult an attorney before responding. Do not engage in a back-and-forth without legal guidance.
  • Recipient complies partially: Acknowledge what they did, reiterate what remains unresolved, and set a new deadline.
  • You are not sure if you have a valid claim: Consult an attorney before sending. A baseless C&D can expose you to liability.
