A cease-and-desist letter can arrive by email, certified mail, or through an attorney. It may accuse you or your business of breaching a contract, copying a brand, disclosing confidential information, or making damaging statements. The letter deserves attention, but its allegations are not established facts. If you received a cease and desist letter, the first steps are to preserve evidence, identify what the sender wants, and assess the legal basis before responding. Here is how California businesses and individuals can approach that process.
Received cease and desist letter: what does it mean?
A cease-and-desist letter is generally a private demand that you stop specified conduct. It may also request payment, removal of content, return of property, or a written commitment about future conduct. An attorney’s letterhead does not turn those demands into a court order.
The sender may be trying to resolve a dispute before filing suit, establish that you received notice, or create a record for later proceedings. Sometimes the claims have substantial support. Other times, the letter overstates the sender’s rights or leaves out important facts.
Read the entire letter and every attachment. Identify:
- Who is asserting the claim and whether an attorney represents them.
- The specific conduct, statements, products, or transactions at issue.
- The rights allegedly violated and any supporting documents.
- What the sender demands, the response deadline, and the threatened next step.
A deadline selected by the sender is not automatically a statutory deadline. Still, ignoring it can mean losing an opportunity to address the dispute before litigation. If the documents include a summons, complaint, injunction, or other court papers, separate legal deadlines or obligations may apply.
Preserve evidence before changing anything
Do not delete emails, texts, files, posts, or account records connected to the allegations. When litigation is reasonably anticipated, preserving potentially relevant evidence becomes particularly important. Destruction can damage your position and, depending on the circumstances, lead to court sanctions.
Save the letter, attachments, envelope, and delivery information. Preserve original files and metadata where possible rather than relying only on screenshots. For a business, identify relevant employees, devices, shared folders, and automatic deletion settings.
- Collect contracts, amendments, invoices, and communications.
- Save dated copies of relevant webpages, advertisements, and social media content.
- Preserve records showing when a name, design, or disputed statement was first used.
- Document the timeline without guessing or rewriting earlier records.
Preserving evidence does not necessarily mean continuing the disputed activity. You may need to pause advertising or restrict access to information. Before removing or modifying material, preserve it and seek advice about whether the proposed change reduces risk or creates another problem.
Assess the claim under the right law
The correct response depends on the claim, not the letter’s tone. California law may govern some issues, while federal law or another state’s law may govern others. A contract’s choice-of-law provision can also matter.
Contract disputes: Compare the allegations with the actual agreement. Look for notice requirements, opportunities to cure, confidentiality provisions, arbitration clauses, and restrictions on using company information. A contractual notice can trigger rights or deadlines even though it is not a court order.
Trademark and copyright claims: Examine who owns the asserted rights and what allegedly infringes them. Registering a California business entity or obtaining a domain name does not, by itself, establish superior trademark rights. Copyright generally protects original expression, not an underlying idea.
Trade secret claims: Not every confidential document qualifies as a trade secret. Under California Civil Code § 3426.1, the definition includes requirements concerning economic value from secrecy and reasonable efforts to maintain secrecy. California Civil Code § 3426.2 permits injunctions against actual or threatened misappropriation.
Defamation claims: The exact words and context matter. Truth and substantial truth can be defenses. Calling something an “opinion” does not automatically protect a statement that implies false facts. Avoid repeating the accusation publicly while evaluating the dispute.
An attorney who advises on California business litigation can assess the evidence, possible defenses, and practical consequences of each response.
Respond deliberately, not defensively
You do not have to accept every demand simply because it appears in a formal letter. But a rushed reply can create admissions, reveal unnecessary information, or commit you to obligations you did not intend.
Depending on the facts, a response might request supporting documents, explain a factual error, propose a temporary pause, reject unsupported demands, or explore a negotiated resolution. Sometimes an attorney should request additional time before providing a substantive response. Do not assume an extension exists until it is confirmed.
Avoid these common mistakes:
- Admitting liability before reviewing the facts and applicable law.
- Threatening the sender or posting the dispute online.
- Signing a settlement, release, or undertaking without reviewing its scope.
- Assuming that labeling an email “confidential” makes it privileged.
If you have insurance that might cover the dispute, promptly review notice requirements and ask about coverage. Keep communications focused and factual. Settlement discussions can be useful, but they do not automatically suspend court deadlines.
