How to Write a Cease and Desist Letter

A cease and desist letter is a formal written demand that someone stop a specific activity — such as breaching a contract — and not resume it. It is often the step just before litigation, and many disputes end right here, because a clear, firm letter shows you are serious and creates a documented record. Here is how to write one that lands.

Our free cease and desist letter template is written for a breach of contract and includes each part below.

1. Header and recipient

Start with the date, your details, the recipient's name and address, and a clear subject line (e.g. "Cease and Desist — Breach of Service Agreement dated 12 March 2026"). A formal header signals this is not a casual complaint.

2. Identify the agreement and the breach

Name the contract that was breached and when it was signed, then describe the specific violation — what the other party did, and when. Be factual and precise. "You have continued to contact our clients in violation of Section 5" is far stronger than vague accusations.

3. Make a clear demand

State exactly what you want the recipient to do: stop the conduct, and not resume it. Ambiguity weakens the letter — spell out the specific actions that must cease.

4. Set a firm deadline

Give a specific date by which they must comply and confirm in writing (for example, within 10 days). A deadline creates urgency and marks the point at which you can escalate.

5. State the consequences

Make clear what happens if they ignore the letter — for instance, that you will pursue legal action and seek remedies including damages and recovery of attorney's fees where the law allows. Keep it firm but factual; avoid threats you are not prepared to follow through on.

6. Tone, delivery, and record

Keep the tone professional and unemotional throughout — a calm, precise letter is more credible than an angry one. Send it in a way you can prove was delivered, and keep a copy. While a cease and desist letter is not usually a contract to be signed, keeping a signed, timestamped copy with an audit trail gives you a clean record of exactly what you sent and when.

A cease and desist letter is often the enforcement step for an agreement someone signed and then broke — such as a non-compete or NDA. If you are still setting those up, see how to write a non-compete and how to write an NDA.
