How to Write a Cease and Desist Letter: Step-by-Step Guide

A cease and desist letter is a written demand that someone stop a specific action, such as using your trademark, breaking a contract, harassing you, or calling you about a debt. It is not a court order, and on its own it is not legally enforceable, but it often comes before a lawsuit. You can write and send one yourself. The work is naming the conduct, citing your right, setting a deadline, and sending it in a way you can prove.

What is a cease and desist letter, and what is it not?

The Tarrant County law library’s research guide defines it as “a cautionary notice sent to an alleged wrongdoer describing the offensive activity and the complainant’s remedies and demanding that the activity stop.” Mycorporation’s guide says the purpose is to get someone to stop “without having the headache, paperwork, and expense of filing a lawsuit against them.”

It helps to know what it is not:

• It is not a court order. Heer Law’s guide says the letter “is not a court order and on its own is not legally enforceable.” Zegal’s guide separates it from a cease and desist order, which it describes as “a legally binding document issued by a court or government agency.”
• It is not court papers. Heer Law’s guide says that if you receive a court order, “you must comply with the order, or you risk being found in contempt of court.” Court papers are a different situation.
• It does not have to be a letter. Heer Law’s guide says the demand “can come electronically” or by telephone call.

Plan around the deadline and the risk of a lawsuit, not on the assumption that the letter forces anything.

What goes in a cease and desist letter?

Zegal’s guide lists what a letter should include. Heer Law and Masterly Legal add a few details. Here is a simple layout you can fill in:

1. Your name, address and the date.
2. The recipient’s correct name and address. Zegal’s guide says getting this right is crucial.
3. A short statement of your right. Heer Law’s guide says letters about intellectual property usually cite the registration number, and that you can enclose a copy of the registration.
4. The specific acts to stop, with dates where you have them. Mycorporation’s guide says to cite the specific action you want stopped.
5. Any harm the conduct has caused you, such as lost money.
6. A deadline to stop or respond.
7. What you will do if they do not comply. Masterly Legal’s guide lists a warning that failure to comply may lead to legal proceedings.
8. Your signature.

Keep the tone direct and professional. Mycorporation’s guide says to avoid emotional arguments, and Masterly Legal warns that an overly aggressive tone can backfire.

How do you send a cease and desist letter?

Zegal’s guide says a letter is usually sent by registered or certified mail to get a delivery receipt, and that it can also go by email, fax, or through an attorney. Its guide says each method provides a trail of delivery. So yes, you can email one. Mycorporation’s guide and Masterly Legal’s guide both recommend certified mail, and Masterly Legal specifically suggests requesting a return receipt.

• Send it certified mail with return receipt requested.
• Keep a copy of the letter and the mailing receipt.
• Record every reply and every call. Mycorporation’s guide calls this record keeping.

Can I write a cease and desist letter without a lawyer?

Yes. Zegal’s guide says you do not need to hire an attorney to send a cease and desist letter. Mycorporation’s guide says you do not necessarily need one, and recommends having an attorney review the letter when the stakes are high. For trademark letters, the USPTO says you are not required to have an attorney to respond, though one can help.

How much does a cease and desist letter cost?

Costs depend on whether you write it yourself, use a template, or hire a lawyer. The figures below come from the sites named in each row.

The Debitura figures are for demand letters, which may not match the cost of a cease and desist letter. Ask a lawyer for a quote on your letter.

How enforceable is a cease and desist letter?

A cease and desist letter is not enforceable by itself, but ignoring it can lead to a lawsuit. Heer Law’s guide says that while there is typically no legal penalty for ignoring the demand, doing so is generally ill-advised. If the letter is ignored, the sender may start a legal proceeding to obtain a court order called an injunction, along with damages and costs. Zegal’s guide says a letter that is ignored can serve as evidence in court, showing the recipient was aware of the problem.

California’s debt rules work differently. The California Courts self-help debt guide says that once a collector gets your letter, the collector must stop contacting you, but “they can still file a lawsuit.”

How long is a cease and desist letter valid?

A cease and desist letter usually names a deadline for the recipient to act, according to Heer Law’s guide and Zegal’s guide. Heer Law’s guide says cease and desist correspondence “also includes a deadline for complying with the demands.” Zegal’s guide says that if the recipient does not comply within the specified timeframe, you may proceed with legal action. Write the date down and track it. If the deadline passes, the sender may take legal action, so ask a lawyer about your situation. The legal deadline organizer can help you keep the dates straight.

For a California stop-contact letter to a debt collector, the rule starts when the collector receives it. The California Courts guide says the collector “must stop contacting you” after it gets your letter, apart from acknowledging your request or saying it will file a lawsuit.

Is a cease and desist letter worth it?

Often, yes, because it is cheap compared with a lawsuit and it creates a record. Mycorporation’s guide calls it the start of a paper trail if further action is needed. Heer Law’s guide says that in some cases the letter opens a path to negotiation. Masterly Legal’s guide says a letter alone “may not always be enough to stop violators.”

A simple test: can you name the exact conduct, can you show it happened, and do you know what you want them to do? If yes, a clear letter is a reasonable first step. If the claim involves money, a trademark, or a court filing, read the section on lawyers below before you send anything.

What are the grounds for a cease and desist letter, including harassment?

Zegal’s guide lists common situations: trademark, copyright or patent infringement, breach of contract, harassment, excessive debt collection practices, and defamation. Heer Law’s guide adds misuse of confidential information. Mycorporation’s guide says that if you are being harassed, bullied, or discriminated against, a letter can tell the other party you intend to pursue legal action if they do not stop.

To write a harassment letter, list each incident with its date, name the behavior you want to stop, state what you want (for example, no more calls), and say what you will do next if it continues. Mycorporation’s guide says to gather evidence before you draft. Keep copies of every message.

For debt collectors, California law sets limits on contact. The California Courts self-help debt guide says a collector can generally call only between 8:00 a.m. and 9:00 p.m., cannot call you at work if your employer prohibits it, and must not harass or abuse you or make false statements. For more, see debt collection rights.

How do you legally tell a debt collector to stop contacting you?

California law gives you the right to demand that a creditor or debt collector stop contacting you. The California Courts self-help debt guide says you must notify them in writing that you want them to stop all communication, or stop one type, such as phone calls.

• Send the letter by certified mail and keep a copy.
• Send a separate letter for each debt if the collector handles more than one account.
• Expect the collector to stop, except to confirm your request or to say it will file a lawsuit.

The federal rule on debt collection is 12 CFR Part 1006. Mycorporation’s guide says the federal Fair Debt Collection Practices Act lets you tell a collector to stop further communication. The Consumer Financial Protection Bureau also publishes sample letters to send to debt collectors.

What does the USPTO say about a trademark cease and desist letter?

The USPTO describes a trademark letter as correspondence that “states or suggests that you are potentially infringing the trademark of another and demands that you stop using, or consider stopping use of, the accused mark.” It says you should treat any such letter seriously. Your options, per the USPTO guide for trademark letter recipients, are:

• Respond. If you have a basis, deny infringement. You can also ask for more specific evidence, including first-use dates, whether the mark is federally registered, and where the mark has been used.
• Do nothing. The USPTO notes that some letters are sent hoping recipients will be misled or intimidated, but says the decision not to respond “carries some risk.”

The USPTO lists ways to challenge a registration, including a petition to cancel with the Trademark Trial and Appeal Board, and an opposition filed within 30 days after publication in the Official Gazette.

How do you respond to a cease and desist letter?

Read the letter slowly and write down the deadline and each demand. Mycorporation’s guide suggests this order:

1. Check whether the claims are valid and whether you are the right recipient. Heer Law’s guide says to ask whether the sender actually holds the rights it claims.
2. Gather documents, emails and contracts that support your position.
3. Do not respond in a hurry, and do not discuss the letter publicly. Heer Law’s guide says comments you make could be used against you later.
4. Choose a path: comply, negotiate, or dispute the claims.
5. Respond by the deadline. If you need more time, ask the sender for an extension, which Mycorporation’s guide says shows good faith.
6. Keep records of every message and call.
