When Is It OK to Threaten Legal Proceedings?

Threatening legal action is legal in Australia, as long as the threat is a genuine step toward resolving a real dispute. A clear warning that you will go to court if an invoice stays unpaid is allowed. The same words become a problem when they tip into blackmail, an unjustified intellectual property claim, or plain harassment.

Here is the part nobody enjoys. A customer has gone quiet on a $9,000 invoice, or a competitor has lifted your logo, and the urge to fire off a “pay up or I’ll sue you” email is strong. Most people freeze at exactly that moment. Is the threat even allowed? Could it land you in trouble instead? Good instinct to pause. The line is real, and stepping over it can flip you from the person owed money to the person being sued.

Is it legal to threaten legal action in Australia?

Yes. You can threaten to sue someone in Australia, and you can say so in writing. The law expects parties to raise a dispute and try to sort it out before anyone files in court. Threatening legal action is the everyday way that happens.

Telling someone you intend to bring a claim is not violence, and it is not a crime. Companies do it constantly. A letter that says “settle this debt within 14 days or we will start court proceedings” is a textbook example, and a lawful one.

What decides it is whether you have a real claim. If the debt is owed, the breach happened, or your rights were infringed, you are on solid ground. A common worry we hear is that any mention of court will be read as a threat in the menacing sense. It won’t, provided you are pointing to a genuine right and a genuine remedy.

When does threatening legal action become illegal?

It crosses the line when the threat is used to get something you are not entitled to. That is blackmail, and it is a serious criminal offence. In New South Wales, section 249K of the Crimes Act 1900 makes it an offence to make an unwarranted demand with menaces, intending to gain something or cause a loss. Every state and territory has its own version.

It comes down to what you are demanding. Telling a client “pay the $9,000 you owe under our contract or I will sue” is lawful. Telling them “pay me $50,000 you don’t owe or I’ll report you to the tax office” is extortion. The first asks for something you have a right to. The second uses pressure to take something you don’t.

Another trap is threatening criminal consequences to win a civil argument. Saying “come back to the negotiating table or I’ll press charges” muddies a money dispute with a threat of prosecution, and that can be treated as a menace. Keep the two apart. Threats of actual physical harm are different again. They fall under common assault and threat offences, which carry jail time, and they have no place in a commercial dispute.

The cease and desist trap: how threatening legal action can get you sued

Here is the one most business owners never see coming. Threaten someone over intellectual property you can’t back up, and they can sue you for the threat itself. Section 129 of the Trade Marks Act 1995 (Cth) lets a person who receives a groundless threat of trademark infringement proceedings take you to court. They can seek a declaration that your threat had no basis, an injunction to stop you repeating it, and damages for any loss you caused.

The same idea runs through the Patents Act 1990, the Designs Act 2003, and the Copyright Act 1968. Australian IP law actively protects people from heavy-handed infringement threats. A real Australian example: in the Stone & Wood “Pacific Ale” beer dispute, a brewer that received an infringement threat ran an unjustified threats argument straight back at the brand owner.

Fixing this is simple. Merely telling someone your trademark exists is not a threat. Telling them you will sue for infringement is. So before you send a cease and desist letter for copyright or trademark, check that your right is registered and actually infringed. Where founders get burned is firing off an aggressive letter about a “brand” they never registered, then getting a counterclaim in reply.

Is threatening legal action harassment?

One firm letter is not harassment. A pattern of baseless threats can be. If you repeatedly threaten legal action you have no intention of taking, purely to intimidate or wear someone down, that behaviour can stray into harassment or intimidation, which carries its own consequences.

Debt collection is where the rules are tightest. A creditor or collector cannot harass, hound, or mislead a debtor. The joint ACCC and ASIC debt collection guideline sets clear limits on how often and how aggressively a debtor can be contacted, and the National Consumer Credit Protection Act 2009 sits behind it. Step over those limits and the threats become the legal problem.

If you are on the receiving end of relentless threats, a cease and desist letter is a clean way to put it in writing and ask the conduct to stop. The short version: threaten once, mean it, and follow a process. Don’t use threats as a pressure campaign.

How to threaten legal action the right way

The vehicle for a proper threat is a letter of demand. It states what you are owed or what must stop, gives a deadline, and spells out what happens next if the deadline passes. Done well, it often ends the dispute on its own, because the other side can see you are organised and serious.

A strong demand letter does four things:

1. Stays calm and professional. Anger weakens your position and can be forwarded around.
2. States exactly what you want: the amount, the action, the outcome.
3. Sets a clear deadline and the consequence, such as “we reserve our right to start court proceedings to recover the debt”.
4. References the contract or right you are relying on, and goes to the right person.

There is a natural ladder if the first letter is ignored. You start with a letter of demand, move to a final letter of demand with firmer language, then a lawyer’s letter on letterhead, which often lands differently. For a company that owes an undisputed debt of $4,000 or more, a statutory demand under the Corporations Act is the next lever. The company has 21 days to pay or be presumed insolvent. The last step is filing a statement of claim and actually going to court.

What we see in Lawpath consultations

This is where the advice gets practical. Across debt-recovery and dispute consultations, a few patterns come up again and again.

Only threaten what you will actually do. The most consistent advice our lawyers give is not to threaten proceedings unless you are genuinely prepared to start them. An empty threat that is never followed up trains the other side to ignore you. The stronger move, especially in a demand letter, is to reserve your rights under the contract and at law rather than bluff a court date you won’t book.

Do the maths before you escalate. Lawyers repeatedly walk clients through the cost-benefit of going legal. Court and small claims action takes time and money, and for a smaller debt the recovery steps can cost more than the debt is worth. A well-aimed letter of demand is cheap. Litigation is not. Weigh that before you escalate.

A statutory demand is not a debt-collection toy. It only works for a company that owes an undisputed debt over the threshold. Fire one off at a debt the other side genuinely disputes and they can apply to have it set aside, often with a costs order against you. Used in the wrong situation, it backfires.

Count the relationship cost. Plenty of clients want their money but also want to keep working with the other party. Going legal can sour a relationship you were hoping to keep. Sometimes a direct conversation, or a firmly worded reminder that stops short of a formal threat, recovers the money and the relationship both.

Can someone sue you for threatening legal action?

In most cases, no. A genuine threat tied to a real claim gives the other side nothing to sue over. There are specific exceptions worth knowing.

• Unjustified IP threats. As above, a groundless trademark, patent, design, or copyright threat can be actioned against you directly.
• Abuse of process. Using the court system for an ulterior purpose, rather than to resolve a genuine claim, can be challenged.
• Malicious prosecution. If you bring a baseless claim with malice and it fails, you can be exposed.
• Harassment or blackmail. Threats that become a campaign, or that demand something you are not owed, carry their own liability.

What ties these together is genuineness. Threaten a real claim in good faith and you are protected. Use the threat as a weapon to grab something you have no right to and the risk swings back onto you.

Frequently asked questions

Can you threaten to sue someone in Australia?

Yes. You can threaten to sue someone if you have a genuine claim, such as an unpaid debt or a breach of contract. Saying you intend to bring proceedings is lawful and common. It only becomes a problem if you are demanding something you are not actually owed.

Is threatening legal action illegal?

No, not by itself. Threatening legal action over a real dispute is legal in Australia. It turns illegal when it becomes blackmail, an unjustified intellectual property threat, or a pattern of harassment used to intimidate someone.

Is it extortion to threaten a lawsuit?

Threatening a lawsuit to recover something you are genuinely owed is not extortion. It becomes extortion, or blackmail, when you use the threat to obtain a benefit you have no legal right to, such as demanding money beyond the debt or threatening to report someone unless they pay.

Is threatening legal action harassment?

One genuine threat is not harassment. Repeated baseless threats designed to intimidate or pressure someone can be. In debt collection, contacting a debtor too often or too aggressively can breach the ACCC and ASIC debt collection guideline.

Can a lawyer threaten legal action on my behalf?

Yes. A lawyer can send a letter of demand or a cease and desist letter on your behalf, and a letter on a law firm’s letterhead often gets a faster response. Lawyers must still keep the threat genuine and avoid making claims that aren’t supported.

What should a letter of demand include?

A clear statement of what you are owed or what must stop, the contract or right you rely on, a firm deadline, and the consequence if the deadline passes. Keep the tone professional. Address it to the right person, and reserve your legal rights rather than over-promising what you will do.

Can I be sued for sending a cease and desist letter?

You can, if the threat is groundless. Under section 129 of the Trade Marks Act 1995, someone who receives an unjustified threat of trademark infringement proceedings can sue you for a declaration, an injunction, and damages. Check that your right is registered and infringed before you send one.

Do I have to follow through on a threat to sue?

You are not legally forced to. But empty threats lose their power fast, and the other side learns to ignore you. Lawpath lawyers advise only threatening proceedings you are genuinely prepared to start, and otherwise reserving your rights instead.

What is a statutory demand?

A statutory demand is a formal notice under the Corporations Act requiring a company to pay an undisputed debt of $4,000 or more within 21 days. If the company does not pay or apply to set the demand aside, it is presumed insolvent, which lets the creditor start winding-up proceedings.

The bottom line

If you are sitting on an unpaid invoice or watching someone take liberties with your work, you are not being aggressive by drawing a line. You are running your business properly. Threatening legal action is a normal, lawful tool when your claim is real and you go about it the right way.

Start with a clear, professional letter that sets out what you want and what happens next. Create your letter of demand today and put the dispute on the front foot.
