If someone is using your brand, copying your content, bad‑mouthing your business, or pressuring your customers, a well‑crafted cease and desist letter can be the quickest way to make it stop.
For Australian businesses, this kind of letter is often the first and most cost‑effective step to resolve a dispute without going to court. Done right, it signals that you understand your rights and you’re prepared to act. Done poorly, it can inflame the situation or even create legal risks of its own.
In this guide, we’ll cover what a cease and desist letter is, when to use one, how to write and send it, and the key Australian laws to keep in mind (including special rules for defamation “concerns notices”). We’ll also share the supporting documents that commonly sit alongside a cease and desist strategy so you can protect your position from day one.
What Is A Cease And Desist Letter In Australia?
A cease and desist letter is a formal written demand asking a person or business to stop certain conduct that you say is unlawful, infringing or otherwise harmful. In plain English, it says: stop now, don’t continue, and fix the harm.
Businesses commonly use cease and desist letters to deal with issues such as:
- Intellectual property problems (for example, someone using your brand name or copying your content)
- Misuse of confidential information or trade secrets
- Misleading and deceptive conduct that’s damaging your business or customers
- Defamatory statements that are harming your reputation
- Contract breaches (like a reseller ignoring territory limits or payment terms)
Think of the letter as an early intervention tool. It’s not a lawsuit. It’s a clear opportunity for the recipient to change course before you escalate.
Cease And Desist Order vs Letter: What’s The Difference?
- Cease and desist letter: A private demand you (or your lawyer) send. It asks the recipient to stop and sets out what you want done.
- Cease and desist order: A court‑ordered injunction or similar relief compelling someone to stop. Ignoring an order can lead to serious penalties, including contempt of court.
Most matters start with a letter because it’s faster and cheaper. If the issue is urgent or the harm is severe, you may skip to court for an injunction-but that’s the exception, not the rule.
When Should You Use One?
Use a cease and desist letter when you can identify specific conduct, link it to a legal right, and provide a reasonable path to resolution. Typical SME scenarios include:
- Brand and content protection: A competitor has started using a confusingly similar name or logo, or has copied your website copy, photos or product descriptions. If you hold (or are pursuing) protection such as a registered trade mark, your position is stronger. Many businesses choose to register their trade marks before or alongside sending a letter.
- Misleading conduct: A rival is making false comparisons or claims about your products. This can raise issues under the Australian Consumer Law’s rules against misleading or deceptive conduct. Read more about section 18 of the ACL.
- Confidential information: A former contractor or employee is using client lists, pricing or processes they shouldn’t have taken. An NDA or confidentiality clause makes your letter more persuasive. If you don’t have these in place yet, consider a Non‑Disclosure Agreement for future dealings.
- Defamation: Someone has published false statements about your business that are causing real harm. In defamation matters, you’ll often need to send a compliant “concerns notice” before you can sue (more on this below).
- Contract breaches: A supplier, reseller or collaborator is ignoring agreed terms. Your letter can point to the relevant clauses and demand compliance.
Less commonly, letters are used for personal harassment or stalking. If there’s any risk to safety or threats of violence, contact police first. For business reputational or commercial issues, a targeted letter is usually the right starting point.
How To Write And Send A Cease And Desist Letter (Step‑By‑Step)
You can draft a letter yourself, but getting it reviewed by a lawyer often improves your leverage and avoids accidental missteps. Here’s a practical roadmap.
1) Map The Facts And Gather Evidence
List exactly what’s happened, when it happened, and who’s involved. Collect screenshots, URLs, copies of ads, emails, contracts and any other documents you’ll rely on. Clear, timestamped evidence makes your demand harder to ignore and easier to escalate if needed.
2) Identify Your Legal Basis
Keep the legal foundation concise but clear. Common grounds include:
- Trade mark or copyright infringement
- Misleading or deceptive conduct under the Australian Consumer Law (ACL)
- Breach of confidence or breach of contract
- Defamation (noting the “concerns notice” rules)
You don’t need a full legal thesis-just enough to show you understand your rights and where they come from. If your brand is central to the dispute, reference your registration or pending application and how you use it in trade (for example, on packaging or your site).
3) Draft The Core Demands
Spell out what you want, by when, and how you’ll verify compliance. Typical demands include:
- Stop the conduct immediately (e.g. cease sales under a confusing brand, or remove copied pages)
- Take down online content (pages, listings, ads, social posts)
- Issue a correction or apology (where appropriate)
- Confirm in writing (with screenshots or declarations) that steps have been taken
- Propose a short timeframe for response (often 7–14 days, depending on the issue)
Include a short “reservation of rights” statement so you’re not waiving any claims if the matter escalates.
4) Choose A Sensible Delivery Method
There’s no one “legally prescribed” way to serve a private cease and desist letter. What matters is that you can show it was delivered. Common options are:
- Email: Fast and practical. Ask for acknowledgment, and keep delivery records. Whether an email itself creates a binding agreement later depends on the context-see this guide on emails being legally binding.
- Registered post or courier: Helpful as evidence of delivery, but not automatic “legal proof of service” for all purposes. Keep the tracking and delivery confirmation.
- Hand delivery or process server: Useful if you anticipate a dispute about receipt, or if you’re preparing to escalate to court where formal service rules apply.
Whichever route you choose, keep a complete record-cover letter, attachments, screenshots, timestamps and tracking details.
5) Manage The Response And Next Steps
Set a clear deadline and hold it. If the recipient:
- Complies: Confirm in writing what was done and when. If appropriate, consider documenting the resolution in a short settlement or release.
- Engages: You might negotiate limited ongoing use, a phase‑out period or other commercial terms. Where money or mutual promises are involved, put it in a proper settlement deed. This is where a Deed of Release and Settlement is useful.
- Ignores or refuses: Consider a follow‑up from a lawyer (on letterhead) or escalation to court action such as an injunction. Weigh the evidentiary strength, urgency and cost‑benefit before filing.
Can I Use A Free Template?
Templates can be a starting point, but they rarely reflect the facts, the right legal grounds, or the best negotiation strategy. A generic threat can backfire-especially in defamation matters or if it overreaches. At minimum, have a lawyer check that your letter’s claims are accurate, that you’re not making inadvertent admissions, and that the remedy you’re seeking is realistic.
Legal Pitfalls And Australian Law You Must Consider
A powerful letter is also a careful letter. Here are the common traps and the rules to keep in mind before you press send.
Defamation: Concerns Notices And “Serious Harm”
- For individuals and certain small corporations, defamation claims generally require a compliant “concerns notice” before you can sue. The notice needs to identify the defamatory matter, convey the imputations, and allow a reasonable time to respond.
- Since 2021, most states and territories have introduced a “serious harm” threshold-your business must show the publication has caused, or is likely to cause, serious harm to reputation.
- Only certain corporations can sue (for example, many larger corporations cannot, unless they meet the “excluded corporation” criteria). If in doubt, get advice before alleging defamation.
If your situation is truly a defamation matter, structure your letter as (or alongside) a concerns notice that meets the legislative requirements.
Misleading Or Deceptive Conduct (ACL)
If the issue relates to advertising claims, false comparisons or market behaviour, anchor your letter in the Australian Consumer Law (ACL). The ACL prohibits conduct that misleads or deceives, and it often provides a clearer path than trying to frame everything as “defamation.” For a refresher, see the overview of section 18.
Australia does not currently recognise a general tort of invasion of privacy. That means you typically won’t have a standalone “breach of privacy” claim just because someone shared information. Instead, look to:
- Breach of confidence: Where information was disclosed in circumstances importing an obligation of confidence (for example, under an NDA or employment agreement).
- Privacy Act obligations: If you’re an entity subject to the Privacy Act, ensure your own data handling (and your letter’s requests) align with your Privacy Policy and the Australian Privacy Principles.
If confidentiality is central to your dispute, having a solid NDA in place makes your letter far more persuasive. You can put one in place for future dealings using a standard Non‑Disclosure Agreement.
Employment And Restraints
Letters to former staff must be measured. Restraint and non‑solicitation clauses are only enforceable to the extent they’re reasonably necessary to protect legitimate business interests. If you’re relying on a restraint, set out the exact clause, the duration and the geographic scope. Overreaching demands may weaken your stance, so get tailored advice.
Intellectual Property Nuances
Not all copying is unlawful and not all rights are registered. In IP disputes, accuracy matters:
- Trade marks: If you own a registered mark, state the registration details and how the other party’s use is likely to cause confusion.
- Copyright: Copyright protects original literary, artistic, musical and dramatic works (including text and images) automatically-registration is not required in Australia.
- Designs and patents: If you rely on a registered design or patent, reference the registration and how the product falls within its scope.
If brand protection is a recurring concern, consider locking in a registration for your key marks through Trade Mark registration.
Threats And Overreach
Avoid threats you’re not prepared to pursue. Don’t exaggerate damages, and don’t misstate the law. Aggressive language can inflame the dispute and may create risk (including the risk of a defamation counterclaim). Keep your tone factual, firm and professional.
Useful Documents That Often Sit Beside Your Letter
A cease and desist letter is more effective when you can point to clear, written rights. Depending on your situation, you may also need:
- Non‑Disclosure Agreement (NDA): Protects confidential information shared with staff, suppliers or collaborators. A tailored Non‑Disclosure Agreement makes any misuse easier to address.
- Privacy Policy: Explains how your business collects and uses personal information, and helps demonstrate your compliance stance in data‑related disputes. See Privacy Policy.
- Settlement Deed: When the other side agrees to stop and you want finality (for example, undertakings, removal of content, and sometimes payment), document it in a Deed of Release and Settlement.
- Trade Mark Registration: If you anticipate ongoing brand issues, a registration strengthens your position. Consider registering your trade mark so future letters carry more weight.
- Contract Clauses: Clear IP ownership, non‑solicitation and exclusivity clauses in your customer or supplier contracts reduce disputes before they start. If the situation is complex, our Legal Advice Package can help you prioritise the right documents.
- Email And Notices: If you’ll be negotiating by email, remember that in some contexts an email can amount to agreement. Here’s a quick explainer on emails being legally binding.
You won’t need every document every time, but the right foundation makes your cease and desist letter more persuasive-and reduces the risk of repeat issues.
Key Takeaways
- A cease and desist letter is a formal, written demand to stop harmful conduct; it’s often the fastest way to resolve an issue without court action.
- It’s different from a court order (injunction). A letter asks; an order compels. Most disputes start with a letter for speed and cost reasons.
- Make your letter factual and precise: identify the conduct, state the legal basis, set clear demands and deadlines, and reserve your rights.
- Be careful with legal pitfalls, especially in defamation (concerns notice requirements and the serious harm threshold), ACL claims, confidentiality and restraints.
- Delivery methods like email or registered post provide useful evidence of delivery, but they’re not universal “legal service” for all purposes-keep thorough records.
- Supporting documents-such as an NDA, Privacy Policy, trade mark registration, and a settlement deed-can significantly strengthen your position.
- If the matter is high‑stakes or complex, getting tailored legal input early can prevent missteps and improve your negotiating leverage.
