Cease and Desist Letter: When to Send One and What to Include

A cease and desist letter is a written demand that the recipient stop a specific course of conduct or face legal action. It differs from a typical demand letter In that the relief sought is not money but conduct: stop using the trademark, stop publishing the defamatory statement, stop calling the sender, stop entering the property, stop competing in violation of the agreement. The letter is most common in trademark and copyright infringement, defamation, harassment, breach of non-compete or non-disclosure, debt-collection abuse, and trade-secret disputes.

What a Cease and Desist Letter Should Include

Section	Purpose
Sender's identity and standing	Trademark registration number, copyright certificate, employment agreement, or other right being enforced
Identification of the conduct	Specific website URL, social media post, statement, product, or behavior
Legal basis	The statute, common-law tort, or contract clause violated
Demand to stop	Specific actions the recipient must take or refrain from
Deadline	Usually 10-14 days for compliance
Consequences	Lawsuit, injunction, statutory damages, attorney's fees
Signature and contact	Sender's identity, signature, return address

When a Cease and Desist Letter Is Effective

Cease and desist letters are most effective when the underlying right is clear and the sender is plainly able to enforce it. A registered trademark holder with a federally registered mark and clear evidence of consumer confusion has a strong case for a quick injunction; the recipient knows that and usually complies. A defamation claim involving a clear false statement of fact published to third parties has similar use. The letter is least effective when the legal theory is novel, the facts are contested, or the sender lacks standing.

The legal basis for a cease-and-desist letter depends on the underlying claim. Trademark infringement claims rest on 15 U.S.C. § 1125(a) (Lanham Act § 43(a)) and the likelihood-of-confusion factors articulated in Polaroid Corp. v. Polarad Electronics Corp., 287 F.2d 492 (2d Cir. 1961). Copyright claims invoke 17 U.S.C. § 501 and the DMCA takedown procedure under 17 U.S.C. § 512(c)(3). Defamation claims rely on state common law and, where the speech concerns a public figure, the actual-malice standard of New York Times Co. v. Sullivan, 376 U.S. 254 (1964). Harassment letters often cite state stalking statutes; federal cyberstalking is criminalized under 18 U.S.C. § 2261A.

Trademark and Copyright Use Cases

For trademarks, the letter should identify the registration number, the goods and services covered, the alleged infringing use, and the consumer-confusion theory. For copyrights, the letter should identify the registration certificate, the original work, the alleged infringing copy, and demand removal under DMCA section 512(c) if the infringing material is hosted by an online service provider. A poorly drafted trademark cease and desist that is published online (the "Streisand effect") often becomes the story rather than resolving it. Our intellectual property team drafts cease and desist letters that do not invite a viral response.

Non-Compete and Non-Disclosure

For non-compete enforcement, the letter must attach the executed agreement, identify the specific clauses breached, and specify the conduct that must stop. Many states (California, North Dakota, Oklahoma, Minnesota, and increasingly through the FTC's now-blocked rule) refuse to enforce non-competes against employees, so the letter should be supported by a careful state-by-state enforceability analysis before it is sent. Sending a non-compete cease and desist that is unenforceable on its face exposes the sender to a tortious interference counterclaim.

Defamation

For defamation, the letter must identify the false statement of fact, the publication (URL, broadcast, written copy), the third-party recipient, and the actual damage caused. Statements of opinion, rhetorical hyperbole, and protected speech under the First Amendment are not defamation; sending a cease and desist over protected speech often produces a viral retaliation post and, in California and a growing number of states, a successful anti-SLAPP motion that awards the recipient attorney's fees.

Harassment and Stalking

For harassment, the letter should describe specific incidents (dates, times, locations, methods of contact), invoke the relevant state harassment or stalking statute, and demand that all contact stop. Combined with a contemporaneous police report and filing for a civil restraining order, the letter strengthens the eventual injunction record. The letter alone is not a substitute for a court-ordered preliminary injunction.

Cease and Desist Letter vs. Restraining Order

A cease and desist letter is private. A temporary restraining order is a court order. The letter has no enforcement teeth except as evidence in a follow-up lawsuit; a restraining order is enforceable by contempt. The letter often precedes the restraining order to establish notice and the recipient's continued conduct, which strengthens the showing of irreparable harm required for injunctive relief.

Common Mistakes

The biggest mistake is sending a cease and desist letter without first verifying enforceability. Sending one based on a non-existent trademark registration, a non-compete that is void in the recipient's state, or a defamation claim covering protected opinion creates legal exposure for the sender. The second is publishing the letter publicly (the "Streisand effect"); the third is using boilerplate language that the recipient and any internet researcher can immediately identify as a template.

A poorly drafted cease-and-desist letter creates exposure under the Lanham Act's reverse-confusion theory or under 28 U.S.C. § 2201 (Declaratory Judgment Act), which the recipient can use to file suit in a forum of their choosing. Under MedImmune, Inc. v. Genentech, Inc., 549 U.S. 118 (2007), the recipient need not breach the asserted right before seeking declaratory relief; the threat alone creates the case-or-controversy. Sending a baseless letter to a competitor can also trigger antitrust liability under Professional Real Estate Investors v. Columbia Pictures, 508 U.S. 49 (1993), if the underlying claim is objectively baseless and a sham.

Frequently Asked Questions

How serious is a cease and desist letter?

A cease and desist letter is the formal step before litigation. It signals that the sender has consulted counsel, has identified a legal theory, and is prepared to seek a court order if the conduct continues. Ignoring a cease and desist letter typically leads to a lawsuit and, in trademark, copyright, and defamation cases, can support a request for statutory damages or attorney's fees against the recipient.

What proof do you need for a cease and desist?

The sender needs evidence of the underlying right (trademark registration, copyright certificate, signed agreement, specific defamatory publication) and evidence of the recipient's conduct (URLs, screenshots, witness statements, sales records). The letter does not need to prove the case beyond a reasonable doubt; it needs to give the recipient enough information to evaluate the claim and decide whether to comply.

Can a cease and desist letter backfire?

Yes. A cease and desist letter can backfire if the underlying right is unenforceable (an expired trademark, a void non-compete, protected First Amendment speech), if it triggers anti-SLAPP fee shifting in defamation cases, if it produces a viral "Streisand effect" public response, or if it is used as evidence of bad faith in a tortious interference counterclaim. A letter drafted by counsel after a state-specific enforceability check rarely backfires.

Can I write up my own cease and desist letter?

Yes. Cease and desist letters are unregulated communications and any party can send one. The risk is asserting a right that does not exist or sending the letter to the wrong party. For trademark, copyright, defamation, and non-compete enforcement, our attorney-drafted letters include a state-specific enforceability check and a clear escalation plan if the demand goes unanswered.
