How to write a cease and desist letter

A cease and desist letter is a formal written demand that someone stop doing something you believe violates your rights, such as copying your brand name or photos. A good one names your right and the proof behind it, and describes exactly what they did and where. Then it lists the steps they must take, and by when. It isn't a court order, but it puts them on notice and starts a dated record.

The letters that work are narrow. They claim only what you can prove, ask for steps the other side can take, and read well if posted online.

Check that a letter is the right tool

First, check whether another route fits better. When the problem is on a website or marketplace, the platform can often remove it faster.

When another route fits better

The problemTry this first
Copied photos, text or designs onlineA takedown notice to the site hosting them
A seller using your brand on a marketplaceThe marketplace's infringement report form
Money they owe youA demand letter for the amount
A client or partner breaking a contractA breach of contract notice in the form the contract requires
Threats of violence or stalkingThe police, or a court protective order

Takedown notices work because US law shields a web host from copyright damages over its users' posts only if it acts "expeditiously" to remove material after a proper notice1. The same law makes anyone who knowingly and materially misrepresents in a notice that something infringes liable for the resulting damages, including attorneys' fees.

A letter also starts a conversation you don't control. In a 2011 report to Congress on trademark disputes, the Commerce Department and the USPTO say recipients tend to comply, ignore the letter or push back. Pushing back can mean suing you first to have a court declare they aren't infringing2.

Pin down your right and your proof

Name the right behind each demand, then gather proof: dated screenshots showing the web address, and any message from a confused customer. When it isn't clear which right applies, write that up first: a legal research memo sets out the question, the rule and how it applies to your facts.

What to check for each kind of claim

ClaimThe right behind itCheck before you write
Your name or logoTrademarkThe registration number and goods covered, or when and where you began using it
Your photos, writing or designsCopyrightThat you made it or own it in writing, and whether and when you registered it
False statements about youDefamationThe exact words, where they appeared, and the facts that prove them false
A broken agreementThe contractThe clause they broke and any notice steps the contract requires
HarassmentState lawA dated log of each incident, with screenshots and witnesses

You don't need a registration to object to a copycat name. But the USPTO says rights built through use may only be enforceable in the parts of the country where you use the mark3.

If you're registered, cite the number. Without the ® symbol or a similar notice on your mark, federal law bars recovering profits or damages unless the infringer had actual notice of the registration4. Your letter gives that notice.

The Copyright Office's guide to the basics5 explains that copyright exists automatically but doesn't cover names or slogans. It belongs to whoever created the work, or to their employer if they made it as part of their job. If a freelancer shot your product photos, the copyright is theirs until they sign it over to you, so get a contractor IP assignment first.

Registration decides what you can threaten. For US works, the same guide says you can't sue until registration is granted or refused. Statutory damages and attorneys' fees are available only if you registered before the infringement began or within three months of publication.

Lay out the cease and desist letter

The 2011 report describes the usual trademark letter. It states the owner's rights, explains why confusion is happening or likely, lists demands and asks for a reply by a set date2. Most problems fit that order, in a page or two.

  1. Heading

    Your contact details, the date, how you're sending it, their name and address, and a subject line.

  2. Your right

    What you own or were promised, and the proof: a registration number, creation date or contract clause.

  3. What they did

    Dated, specific conduct with links, and each screenshot or document listed as an enclosure.

  4. What they must do

    Each step, one calendar deadline, and a request to keep relevant records, such as sales data.

  5. Close

    A line reserving your other rights, your signature and a list of enclosures.

Re: Use of the LUNEBLOOM name on your Etsy shop

We have sold LUNEBLOOM candles since 2019, and the name is federally registered for candles (U.S. Reg. No. 7,XXX,XXX, copy enclosed).

Since March, your shop, Lunebloom Candle Co., has sold candles under our name (listings linked below). Two customers have asked if we opened a second store (emails enclosed).

By November 20, please remove these listings, stop using the name on Etsy and Instagram, and confirm in writing. Please keep your sales records for these listings.

If you believe you have a right to use this name, tell us by the same date and we will consider it.

  • Names the right. The registration, the goods it covers and the certificate.
  • Shows real confusion. Two customer emails show confusion instead of just asserting it.
  • Asks for doable steps. Named listings and channels, one date and written confirmation.
  • Leaves a door open. Inviting their side keeps the tone reasonable and surfaces any earlier claim to the name.

Keep every line defensible

Ask for steps they can finish: remove these listings, stop using the name on these channels, correct this post, confirm in writing. Allow 10 to 14 days for most fixes and longer for big ones, like renaming a business. Ask for money only if you can justify the figure.

Cut anything you couldn't defend to a judge: insults, guesses about motive, threats of criminal charges in a business dispute, and claims of deliberate copying you can't prove.

With false statements, quote the words once and say what is true. Aim at a fact someone can check, such as "they never shipped my order," not an opinion like "worst shop ever."

Don't threaten honest reviewers

Since October 2024, an FTC rule has barred using an "unfounded or groundless legal threat"6 to get a consumer review removed. The FTC says you can still threaten legal action over a review that defames you if you have a legitimate basis.

Send it and plan your next step

Email it, and send a copy by tracked mail with a delivery receipt to prove when it arrived.

Decide now what you'll do if the date passes. When a recipient stays silent, the 2011 report says, trademark owners often send a follow-up letter2, then drop the matter or sue.

For copyright claims up to $30,000 in total, the Copyright Office's Copyright Claims Board7 is a cheaper option than federal court. You need at least a pending registration application, the other side can opt out, and the board can't order anyone to stop unless they agree.

If they agree to stop on terms, such as a few weeks to sell off stock, put the deal in a settlement agreement.

Before you send it

  • Every right you claim matches a document you hold
  • Their conduct is dated, with links and screenshots
  • Each demand is specific, with one calendar deadline
  • Nothing aimed at an honest review or an opinion
  • No insults, guesses about motive or empty threats
  • Your next step is decided if the date passes

When to involve a lawyer

Have a lawyer read the letter first if you would really sue, if the other side has a lawyer, or if the claim is defamation. This guide offers general information about US law, not legal advice.

The tool at the top of this page turns your facts and screenshots into a draft, with every gap marked for you to confirm.

How it works

Start by describing what the other side is doing and what is yours, and add whatever proof you have: links, screenshots, a registration or the contract. River fits the letter to the kind of problem, ties each demand to a right your evidence supports, and checks state rules where they matter. It writes the letter in your workspace and marks every fact you still need to confirm. Nothing goes out until you send it.

If someone copied your photos or writing onto a platform, River tells you a takedown notice may be faster and offers to write one. If what you describe includes threats of violence or stalking, it tells you that's a matter for the police or a protective order, not just a letter.

  1. Describe the problem

    Say what they're doing and what is yours, with links. Attach screenshots, your registration or the contract.

  2. River checks the basis

    It ties each demand to a right your evidence supports and checks state rules where they apply.

  3. Get your letter

    A business letter of one or two pages in your workspace, with a list to check before sending.

  4. Edit or rework it

    Change anything, or ask River for a gentler first request, a final notice or a takedown notice.

What you get

  • A letter fitted to your problem: a copied name, copied work, false statements, a broken contract or harassment
  • Each right stated only as far as your evidence goes, with registration numbers, dates and clauses cited
  • What they did, described with dates and links, and your screenshots and documents listed as enclosures
  • Specific demands they can carry out, a reasonable deadline and a request to keep relevant records
  • Missing facts marked for you to confirm, never filled in with invented names, numbers or dates
  • A checklist of facts to confirm, how to send it, and whether a lawyer should read it first

Common questions

Is a cease and desist letter legally binding?

No. A cease and desist letter is a formal request, not a court order, and the recipient doesn't have to reply. It still matters. It puts them on notice of your rights and gives them a cheap way to fix the problem. It also creates a dated record you can later show a platform or a court.

How long should I give them to respond?

Give them 10 to 14 days for simple fixes like taking down content, removing listings or renaming an online shop. Allow more time for bigger changes, such as renaming a whole business or replacing printed packaging. Name a calendar date rather than a number of days, and choose one you're ready to act on.

Do I need a lawyer to send a cease and desist letter?

No. Anyone can write and send one. Bring in a lawyer if you would really sue, or if the recipient already has a lawyer or far more money. The same goes for defamation claims, where a careless letter can make things worse. Paying a lawyer to review a draft you wrote yourself is a middle path.

What happens if they ignore a cease and desist letter?

Nothing happens on its own; the next move is yours. Common options are a final follow-up letter, a takedown notice or report to the platform hosting the material, a Copyright Claims Board case for copyright disputes, or a lawsuit. Choose your next step before you send the first letter, so the deadline carries weight.

Can I send a cease and desist letter over a bad review?

Only if the review states something false about you as fact and you can prove it. An honest negative review or an opinion isn't a fair target. An FTC rule in force since October 2024 bars groundless legal threats aimed at getting reviews removed. For a false statement, quote it, show what is true and ask for a correction.
