How to Write a Cease and Desist Letter in Michigan

To write a cease and desist letter in Michigan, put six things on the page: who you are and what right you hold, exactly what the recipient is doing that violates it, the law or agreement they are breaking, what you want them to do, how long they have to do it, and what happens if they don’t. Then send it by certified mail with return receipt requested so you can prove it arrived. No Michigan statute dictates a format, and the letter itself carries no binding legal force, but a clear, documented demand sets up every move that follows.

Why Format and Delivery Matter More Than the Letter Itself

A cease and desist letter is a formal written demand telling someone to stop specific conduct that violates your rights. It is not a court order. The recipient faces no automatic penalty for ignoring it. The letter’s power is strategic: it establishes that you identified the problem, communicated it clearly, and gave the other side a chance to fix things before you filed suit.

That record matters. Michigan judges routinely consider whether the parties tried to resolve a dispute informally before litigating. A sender who can show a clear, reasonable demand letter looks cooperative. A recipient who ignored it looks like the opposite, and that perception can shape how a judge approaches remedies and attorney fees.

In intellectual property cases, the letter also fixes the timeline for “willfulness.” Once a recipient has been told in writing that their use of your trademark or copyrighted work is infringing, continued use is much harder to call innocent. Under federal copyright law, willful infringement can push statutory damages from a maximum of $30,000 per work to $150,000 per work.¹ That jump in exposure is often the single most persuasive reason a recipient takes the letter seriously.

What to Put in the Letter

Cease and desist letters operate under general principles of contract and tort law rather than any dedicated Michigan regulatory scheme. There is no required template. What separates an effective letter from one that gets filed and forgotten is substance in six specific places.

Identify the right you hold. Specify what you own or control: a registered trademark, a copyright, a trade secret, a non-compete, a confidentiality agreement. Include registration numbers, contract dates, or other specifics that make the claim concrete rather than vague.
Describe the conduct. Explain exactly what the recipient is doing that violates those rights. Attach screenshots, photographs, or copies of the offending material. Vague allegations invite dismissal.
State the legal basis. Identify the law or agreement being violated without pasting statutory text. “Your use of our logo violates federal trademark law” is more effective than quoting the Lanham Act at length.
State your demands. Say precisely what you want: stop using the mark, take down the content, return confidential documents, honor the non-compete.
Set a deadline. Give a reasonable window, typically 10 to 14 days. The Michigan Gaming Control Board, for example, gave an unlicensed operator 14 days to comply in a recent enforcement action.²
Spell out consequences. Describe the legal action you intend to pursue if the deadline passes: injunctive relief, damages, the specific statutes you will invoke.

One drafting rule overrides everything else: every factual claim in the letter has to be accurate. Accusing someone of conduct they did not engage in exposes you to defamation liability under Michigan law. Stick to what you can document.

Tailor the specifics to the right you are enforcing. For a trademark claim, cite the registration, the date of first use, and the conduct creating confusion; a successful plaintiff under federal law can recover the infringer’s profits, actual damages, and litigation costs, with treble damages mandatory in counterfeit-mark cases absent extenuating circumstances.³ For a copyright claim, check your registration status before you send: you cannot recover statutory damages or attorney fees unless you registered the copyright before the infringement began or within three months of first publication.⁴ Without timely registration, the letter can still demand that the infringer stop, but your biggest financial threat loses its teeth.

For trade secrets, Michigan’s Uniform Trade Secrets Act lets a court enjoin the misuse and, where the secret has already been disclosed, extend the injunction long enough to erase any unfair advantage the misappropriator gained.⁵ The owner can recover actual losses plus unjust enrichment, or alternatively a reasonable royalty.⁶ Sending the letter does double duty here: it demands the conduct stop and it documents that you are actively protecting the information, which matters because trade secrets can lose protected status if the owner fails to take reasonable steps to keep them secret.

For a non-compete or confidentiality agreement, Michigan law allows enforcement only if the restrictions are reasonable in duration, geographic scope, and type of work restricted. If a court finds a restriction unreasonable, it has authority to narrow the agreement and enforce the revised version rather than throw it out.⁷ That reform power makes the threat credible even when the agreement is arguably overbroad, which is worth noting in the letter itself.

For harassment or stalking, point to the pattern of conduct. Michigan criminal law defines stalking as a willful pattern of repeated, unconsented contact that would cause a reasonable person to feel threatened, frightened, or harassed, including following, showing up at a home or workplace, repeated calls, and unwanted messages. The letter creates clear evidence that the recipient was told to stop, which strengthens any later criminal complaint or civil protective order request.

For debt collection, the mechanics are different because federal law gives you a specific right to invoke. Under the Fair Debt Collection Practices Act, a written notice to a third-party debt collector that you want communications to cease forces them to stop, with narrow exceptions: a single final notice confirming the end of collection, or notice that they intend to pursue a specific legal remedy such as filing suit.⁸ This protection applies only to third-party collectors, not to the original creditor.

How to Deliver It

Delivery method decides whether you can later prove the recipient actually received the letter. “I sent it” means nothing in court without evidence that it arrived.

USPS Certified Mail with Return Receipt Requested is the standard. The green card comes back signed by the recipient or their agent, giving you a dated record of delivery. That date is the start of your compliance clock.

A private process server is the stronger option when the recipient is evasive or likely to refuse mail. Process servers provide a sworn affidavit of delivery that carries significant weight in court. Fees generally run $20 to $300 depending on location and complexity.

Email alone is usually not enough. It can supplement a mailed letter — sending a PDF the same day you mail the hard copy is reasonable — but relying on email makes it easy for the recipient to claim they never saw it. Where email is the established channel for an ongoing contractual relationship, it carries more weight, but a mailed backup is still the safer practice.

Lines You Should Not Cross

A cease and desist letter is a legitimate tool, but senders can create problems for themselves by overreaching. The two biggest hazards are threats that go too far and demands based on rights you do not actually hold.

If an attorney is drafting the letter for you, Michigan’s Rules of Professional Conduct prohibit tactics whose primary purpose is to embarrass, delay, or burden a third party rather than to advance a legitimate claim.⁹ A letter threatening meritless litigation purely to intimidate someone can expose the attorney to disciplinary action.

Threatening criminal prosecution in a civil demand sits in a gray area. Under widely followed ABA guidance, an attorney may reference possible criminal charges only if the criminal matter is genuinely related to the civil claim, there is a good-faith basis for both, and the attorney is not trying to improperly influence the criminal process. A letter saying “pay me or I’ll have you arrested” without those conditions looks less like advocacy and more like extortion.

The U.S. Patent and Trademark Office has studied what it calls “trademark bullying,” meaning enforcement tactics that assert rights beyond any reasonable interpretation of what the owner actually holds.¹⁰ Aggressive letters to small businesses over marks that create no real consumer confusion are the classic example. If the sender follows through with a lawsuit, courts can impose sanctions under Federal Rule of Civil Procedure 11 for frivolous claims.

One more consideration worth knowing before you send: Michigan has enacted the Uniform Public Expression Protection Act, an anti-SLAPP law that protects people from being sued in retaliation for exercising free speech, petition, or assembly rights on matters of public concern. If your letter is aimed at a negative review or public criticism rather than genuinely tortious conduct, following up with a defamation suit can backfire; the target can move for early dismissal and recover attorney fees if you cannot show a genuine probability of winning.

What It Costs

An attorney-drafted letter generally runs from $50 for a straightforward template-based letter to $1,500 or more for a complex intellectual property or trade secret demand requiring real research and evidence gathering. Many Michigan attorneys offer flat-fee arrangements for this work. Certified mail costs a few dollars; a process server, as noted, typically runs $20 to $300.

Whether that expense pays off depends on what you are protecting. For a business facing ongoing trademark infringement that threatens its brand, a $500 attorney-drafted letter that stops the problem is an extraordinary bargain against the $50,000 or more that trademark litigation can cost. For a personal harassment situation, even a self-drafted letter sent by certified mail is effective as a documented first step toward legal protection.

What Happens After You Send It

A well-drafted letter produces one of three responses: compliance, a counter-letter opening negotiation, or silence. If the recipient complies, keep the signed return receipt and any written confirmation; that record closes the matter and documents resolution if the issue ever resurfaces. If they push back with a response disputing your claims, you have the start of a negotiation, and the specifics in your original letter give you ground to stand on.

If they go silent past the deadline, your next step is typically filing suit. The letter itself did not create liability, but the paper trail you built now works for you. In intellectual property cases the financial exposure a defendant faces at that point can dwarf the cost of early compliance. Copyright statutory damages alone range from $750 to $30,000 per work, up to $150,000 for willful infringement.¹ In trade secret cases, continued use after notice virtually guarantees a finding of willful misappropriation, which opens the door to broader injunctions and higher damages.⁶ A judge who sees that the defendant received a clear, reasonable demand and did nothing is unlikely to treat their later conduct as innocent.
