My Business Received a Cease and Desist Letter (Missouri)

The one thing you should not do is nothing. Ignoring a letter with real legal merit behind it often invites the very lawsuit it threatens, sometimes a fast-moving one. But you also shouldn't panic and comply with an overbroad demand you don't actually owe. This guide is about moving deliberately: understand what kind of claim you're facing, protect your evidence, and pick the calmest response that protects your business.

First, understand what a cease-and-desist letter actually is

It helps to demystify the thing in your hand before you react to it.

• It's a demand letter, not a court filing. No one has a judgment, an injunction, or any order against you. The letter cannot fine you, freeze your accounts, or force you to do anything on its own.
• But it's not nothing, either. A meritorious letter is often the last step before a lawsuit — or before the sender asks a judge for a temporary restraining order to make you stop immediately. Treating it as junk mail is how a manageable dispute becomes an expensive one.
• It usually has three parts: an assertion that you're doing something wrong, a demand that you stop (and sometimes pay for what you've done), and a deadline with a threat of legal action if you miss it.
• You generally can't tell a bluff from a real threat by looking. Some letters are aggressive overreaches; others are backed by a claim that would win in court. The only reliable way to know is to assess the legal merits.

Identify the type of claim, because the response differs

Read the letter closely and figure out what they're actually accusing you of. The category drives everything that follows.

• Trademark, copyright, or patent infringement. They claim your name, logo, content, or product copies theirs. These intellectual-property demands are common and often time-sensitive.
• Trade-secret or non-compete violation. Frequently aimed at a business that hired a competitor's former employee, alleging stolen confidential information or a breached restrictive covenant.
• Defamation. A claim that something you (or your business) published is false and damaging — a review, a social post, a marketing statement.
• Debt collection. A demand for money allegedly owed. If it comes from a collector rather than the original creditor, separate consumer-protection rules may apply.
• Breach of contract. An assertion that you violated an agreement and must stop or cure the breach.
• Harassment or unwanted contact. A demand that you stop contacting a person or business.

Pin down exactly what they want — stop doing X, hand over an accounting, pay a sum, or some combination — because your options narrow or widen depending on it.

What NOT to do

This is the part where good businesses accidentally hurt themselves. Avoid all of the following:

• Don't ignore it. Silence on a meritorious claim is often read as defiance and accelerates a lawsuit.
• Don't call or email the sender to argue — or to admit anything. An off-the-cuff "well, I did use that name, but…" can become evidence against you. Any explanation should be deliberate and, usually, sent through counsel.
• Don't alter, delete, or "clean up" any related records. Once you reasonably anticipate litigation, you have a duty to preserve evidence. Issue a litigation hold: tell your team in writing to stop deleting relevant emails, files, texts, and documents. Destroying evidence is spoliation, and courts can punish it harshly — with adverse jury instructions, sanctions, or worse — even if your underlying position was strong.
• Don't panic-comply with an overbroad demand. Many letters ask for far more than the sender is entitled to. Caving to all of it without assessing the claim can cost you money, rights, or business you never had to give up.

What TO do, in order

Here's the calm, protective sequence.

• Calendar the deadline. If the letter states a date to respond or comply, put it on the calendar immediately so it doesn't pass while you decide.
• Preserve the letter and everything around it. Keep the envelope, note the date you received it, and gather every document, email, contract, and file related to the dispute. This is the litigation hold in action.
• Soberly assess the merits. Set aside how the letter made you feel and ask the hard question: are they actually right? Did you use their mark, breach the contract, publish something false? An honest read of the merits drives every decision that follows.
• Have counsel evaluate it — and usually send any response. A Missouri attorney can tell you whether the claim is strong, weak, or a bluff, and a lawyer's response letter signals you're taking it seriously without you saying anything you'll regret.
• Then choose your path. Once you know the merits, pick from the options below rather than reacting to the deadline.

Your options, from softest to firmest

You rarely face a binary of "obey or get sued." Match the response to the merits and the relationship.

• Comply. If the claim is clearly valid and compliance is cheap — change a name you didn't have rights to, take down infringing content — sometimes the smartest move is to fix it and document that you did.
• Negotiate. Many disputes settle. You might agree to phase out a name, license the thing in question, pay a reduced amount, or set terms both sides can live with. A negotiated resolution is usually cheaper than a fight.
• Reject with an explanation. If you believe you're in the right — your use is lawful, the contract wasn't breached, the statement was true — a measured response laying out why can end the matter, because many senders are testing whether you'll fold.
• Ignore it — but only on advice. Occasionally the right call is no response, when the demand is baseless and a reply would only invite engagement. Make that choice only after counsel has assessed the merits, never as a reflex.

How to keep this from becoming a lawsuit

A courtroom is slow and expensive, and most of these disputes never get there.

• Respond, even if briefly. A timely, professional response — or your attorney's — signals you're engaged and often opens the door to settlement instead of filing.
• Lead with the merits, not emotion. Whether you're complying, negotiating, or pushing back, a sober, factual posture defuses far better than indignation.
• Get any resolution in writing. If you settle or agree to change something, put it in a signed agreement so the matter is truly closed and can't be reopened later.
• Keep your litigation hold in place. Don't relax it the moment things feel calmer; preserve records until the dispute is genuinely resolved.
