Key Takeaways
- Directors who misuse confidential information or divert business to their own company can face personal liability and see their company held jointly responsible under English law.
- If you suspect a director is conspiring to harm your business, you should act immediately, as delay can weaken your legal position and limit available remedies.
- Remedies for victims of unlawful means conspiracy include damages, injunctions, account of profits, and constructive trust, often providing stronger recovery options than other claims.
- The Companies Act 2006 sets out directors’ duties, and breach of these duties can count as “unlawful means” supporting a conspiracy claim.
- Ignoring suspected fraud or conspiracy can allow further loss, diminish your recovery prospects, and risk losing the chance to secure urgent court orders.
- Our team at Go Legal is experienced in director disputes, breach of duty, and conspiracy claims, supporting both claimants and directors across England and Wales.

Can a Company and Its Sole Director Be Liable for Unlawful Means Conspiracy in England and Wales?
Most business owners believe that a company and its sole director always act as one and cannot conspire together under civil law. However, a recent High Court decision has confirmed that both a company and its director can be held liable for unlawful means conspiracy, even where the director is the only controlling mind. This closes a key legal loophole, significantly raising the stakes in director disputes and commercial fraud cases.
If you are worried about a director diverting business, misusing confidential information, or orchestrating losses through their own company, these clarified rules provide a powerful legal route to secure damages, injunctions, or an account of profits. This article explains what counts as unlawful means conspiracy, sets out the essential elements, and shows why breaches of the Companies Act 2006 or breaches of fiduciary duty are now more likely to trigger serious legal consequences for both directors and the companies they control.
For business owners, directors, and claimants, understanding unlawful means conspiracy is vital to protecting your position and maximising your recovery options. Our London-based solicitors at Go Legal have extensive experience in handling these complex claims across England and Wales.

What Is Unlawful Means Conspiracy in English Law?
Unlawful means conspiracy is a civil tort in England and Wales that allows a claimant to recover losses caused by a coordinated scheme involving two or more parties using illegal or wrongful acts to inflict harm. The tort is significant because it makes all participants in coordinated wrongdoing jointly liable, broadening the scope for compensation and strategic relief.
To succeed in an unlawful means conspiracy claim, the claimant must prove four essential elements:
- There was a combination or agreement between at least two legal persons.
- The parties took coordinated or concerted action, not merely similar steps by coincidence.
- They employed unlawful means, such as breaching contracts or fiduciary duties, fraud, or other civil or statutory wrongs.
- The conspirators intended to cause, and did cause, loss or damage to the claimant as a result of the scheme.
This tort is particularly useful where the harm results from group actions that single-party claims cannot fully address. It also encourages accountability by imposing joint and several liability, ensuring claimants are not left bearing the loss if a single wrongdoer cannot pay.
If you believe you have experienced financial losses due to a coordinated scheme involving directors, partners, or competitors, our solicitors can help assess whether unlawful means conspiracy is the right claim for your situation.
Can a Company and Its Sole Director Be Liable for Unlawful Means Conspiracy?
A company and its sole director can be liable together for unlawful means conspiracy. English law treats a company as a separate legal person from its directors, even when the same individual owns and controls both.
Civil courts focus on whether there is a combination between two legal persons, rather than whether two distinct human minds are involved. While criminal conspiracy typically requires two independent psychological actors, civil conspiracy does not. What matters is whether the company and director acted in concert using unlawful means to inflict loss.
Recent High Court clarification underlines that as long as a director and their company coordinate wrongful acts (such as diverting business, misusing information, or breaching duties), both may be liable in conspiracy. The company’s separate legal status is decisive, not the director’s control.
What Are the Legal Elements of Unlawful Means Conspiracy?
A successful unlawful means conspiracy claim in England and Wales requires careful proof of four elements.
Combination or Agreement: What Type of Conduct Is Required?
There must be a genuine combination or understanding between at least two legal persons. This does not require a signed contract. Informal collaboration, evidence of joint purpose, patterns in conduct or communication can suffice. Courts are prepared to infer an agreement if circumstances strongly suggest coordinated action.
What Counts as “Unlawful Means” in a Conspiracy Claim?
Unlawful means covers a broad range of civil wrongs and statutory breaches that are central to the scheme. Examples include:
- Breach of contract, such as redirecting opportunities from one company to another
- Breach of fiduciary duty, for instance a director using confidential information for personal gain
- Acts of fraud, including misrepresentation or deceit
- Breach of statutory duties, such as those imposed on directors
- Misuse of confidential information
- Criminal offences or contempt of court committed as part of the scheme
The unlawful act must play a crucial role in the injury suffered by the claimant.
Is Intention to Injure Always Needed?
Civil conspiracy liability generally requires an intention to injure the claimant, but the law interprets “intention” to include cases where defendants knew their conduct would inevitably result in harm, even if harming the claimant was not their exclusive or dominant purpose.
How Does Loss to the Claimant Arise?
The claimant must show that actual loss, typically financial but sometimes reputational, flowed directly from the conspiracy. The causal link between the unlawful acts and the loss must be clear.
Sarah, as sole director of her agency, secretly sets up a new company to take over key clients using confidential lists she accessed in her role. Both Sarah and her new company could be liable for conspiracy if they jointly pursued this plan using unlawfully obtained information and caused her original agency to lose business.
Is Knowledge That Acts Are Unlawful Required for Liability in Unlawful Means Conspiracy?
Liability for unlawful means conspiracy does not always depend on the conspirators’ knowledge that their acts are unlawful. The more commonly accepted legal position is that it is sufficient for the parties to know the facts that make their conduct wrongful, even if they do not realise those facts constitute a legal breach.
A person can be liable if they voluntarily participate in acts that turn out to be unlawful, despite not knowing the technical legal classification at the time. Courts focus on whether the participants appreciated the key facts and intended the consequences, not on their legal expertise.
What Is the Difference Between Lawful and Unlawful Means Conspiracy?
Lawful means conspiracy and unlawful means conspiracy are distinct in the nature of the conduct and the required intention.
Lawful means conspiracy involves acts that are themselves legal, but are undertaken predominantly to harm the claimant. The main goal must be to injure. By contrast, unlawful means conspiracy involves using acts that are illegal or wrongful as part of the scheme. Here, intention is interpreted more broadly — harm to the claimant need only be a likely or inevitable result, not the main purpose.
Comparison Table: Lawful vs Unlawful Means Conspiracy
| Feature | Lawful Means Conspiracy | Unlawful Means Conspiracy |
|---|---|---|
| Purpose | Predominant aim to injure the claimant | Harm can be incidental or inevitable, not necessarily primary aim |
| Conduct | All acts are lawful | Scheme involves unlawful acts (e.g. breach of fiduciary duty) |
| Examples | Aggressive but legal price competition to harm a rival | Directors misusing company information to set up in competition |
| Proof | Both combination and predominant intent needed | Combination and use of unlawful means needed |
| Defences | Justification (e.g. acting in self-defence) may apply | Fewer available due to illegality of conduct |
Two companies agree to price undercut a rival, aiming mostly to damage its business, but all their actions follow market regulations. This is a lawful means conspiracy. If they commit fraud, steal trade secrets, or use information obtained in breach of duty, it becomes an unlawful means conspiracy.
How Do You Prove Unlawful Means Conspiracy in Practice?
To prove unlawful means conspiracy, you must assemble clear evidence that each element is met.
What Evidence Do You Need for a Strong Claim?
- Records of communication (emails, calls, messaging) showing planning or collusion
- Evidence of actions consistent with a joint plan: unexplained transfers, simultaneous resignations, coordinated moves between defendants
- Documents evidencing misuse of property, confidential information, or assets by the conspirators
- Proof that the unlawful means were integral to the damaging conduct
How Detailed Must Your Particulars of Claim Be?
The particulars must set out:
- The individuals or entities involved and their roles
- The nature of the agreement or understanding
- How the unlawful acts were carried out and their connection to your loss
Absolute proof at the outset is not required, especially if the opponent controls key documents. Circumstantial evidence that makes the case plausible is sufficient to start; fuller evidence can emerge through disclosure.
What Is the Standard and Burden of Proof?
You must prove unlawful means conspiracy on the balance of probabilities. The claimant carries the initial burden. Where facts strongly suggest conspiracy, the defendants may need to give a credible explanation for coordinated conduct or rebut any adverse inferences.
Jack suspects his business partner and a rival company conspired to divert a contract. He finds messaging evidence, tracks joint bank transactions, and uncovers staff resigning in sequence, all suggesting a coordinated plan. Even without a formal written document, these patterns can help establish conspiracy in court.
What Types of Conduct and Remedies Apply in Unlawful Means Conspiracy Cases?
Which Unlawful Means Are Most Common?
The most common forms of unlawful conduct underpinning conspiracy claims include:
- Breaches of contract in supplier or client relationships
- Breaches of fiduciary duty by directors, such as business diversion or misuse of company resources
- Fraud or deceit, including false invoicing or misrepresentation
- Misuse of confidential information or trade secrets
- Breach of statutory duties owed by directors
- Offences or contempt of court if court orders are breached as part of a scheme
The unlawful act must be an essential part of the conspirators’ plan, not merely incidental.
What Remedies Are Available?
Remedies for successful claimants may include:
- Court orders restraining ongoing or future unlawful conduct (injunctions)
- Orders for delivery up of misappropriated assets or confidential information
- An account of profits, compelling defendants to give up illicit gains
- Declaration that assets are held on constructive trust for the claimant, giving protection if a wrongdoer becomes insolvent
- Damages for all directly caused losses
- Adverse costs orders
What Laws and Deadlines Apply to Unlawful Means Conspiracy in England and Wales?
Unlawful means conspiracy is a common law cause of action, shaped by judicial decisions rather than specific statute. Limitation periods apply strictly, but the precise deadline may depend on the facts and the nature of the underlying wrong.
A short, strictly enforced deadline will apply. Always check the current period before acting to avoid your claim being time-barred.
What Is the Difference Between Unlawful Means Conspiracy and Other Economic Torts?
Unlawful means conspiracy is unique in requiring group action. Other economic torts can involve a single wrongdoer.
How Does Conspiracy Overlap With Inducing Breach of Contract or the Unlawful Means Tort?
- Unlawful means conspiracy: At least two legal persons act together using unlawful means to cause loss to the claimant.
- Unlawful means tort: One party intentionally causes loss to a claimant by unlawfully interfering with a third party’s freedoms or contracts.
- Inducing breach of contract: The defendant persuades or causes another party to breach a contract with the claimant.
Conspiracy claims are particularly useful when multiple individuals or companies are involved, strengthening the claimant’s position by widening the pool of liable defendants.
Alex and Jamie coordinate a plan to hack a competitor’s systems and take customer data, leading to diverted business. That is an unlawful means conspiracy. If only Alex acts alone, even against the competitor, that may be the unlawful means tort but not conspiracy.
Step by Step: What Should You Do if You Suspect Unlawful Means Conspiracy?
Respond quickly and strategically if you suspect a coordinated scheme against your business or reputation.
For Claimants
- Act immediately to secure and save all relevant evidence: emails, financial records, call logs, and other documentation.
- Seek specialist legal advice at the first signs of collusion or business diversion.
- If harm is ongoing, consider seeking interim court orders (such as freezing injunctions or orders requiring delivery up of information) to protect assets or evidence.
- List all potential defendants, including those who may have benefited indirectly.
- Work with your lawyers to draft a claim covering conspiracy, breach of duty, and any related claims to maximise your options.
For Directors and Companies Accused
- Obtain independent legal advice immediately; delay can increase risks and prejudice your defence.
- Retain and preserve all records and correspondence, even if unflattering.
- Strictly comply with court orders. Disobeying an injunction or freezing order risks contempt of court or further penalties.
- If the facts are against you, consider mediation or early settlement. Conspiracy litigation is expensive and the consequences of an adverse judgment are serious.

Frequently Asked Questions
What is an “agreement” or “combination” in conspiracy claims?
This refers to an arrangement or understanding, which can be informal or unspoken, between two or more parties to pursue a coordinated scheme. A formal contract is not required; the agreement can be inferred from conduct or context.
Does a company and its sole director count as “two persons” for conspiracy?
Yes. English law recognises that a company is separate from its director. Together, they can form the necessary combination for conspiracy liability.
Can breach of fiduciary duty support an unlawful means conspiracy claim?
Yes. Breach of fiduciary duty is a common example of an unlawful act that supports a civil conspiracy claim, especially in disputes involving directors.
How is intention to injure the claimant proven in these cases?
Intention may be shown by the defendants’ awareness that their actions would necessarily or inevitably cause the claimant harm, even if that was not their primary aim.
If the director believed their acts were permitted, can they still be liable?
Yes. Liability may be imposed if the director knew the facts constituting the breach or wrongful act, even if unsure those facts were unlawful.
What if the only harm is to a competitor’s business reputation or goodwill?
Loss to reputation or competitive standing can suffice if it flows directly from the conspiracy and the unlawful acts involved.
How do courts distinguish between conspiracy and normal commercial competition?
Courts look for group action involving unlawful conduct. Aggressive but legal business tactics are not enough; there must be an actual agreement and wrongful acts.
What is the limitation period for bringing an unlawful means conspiracy claim?
A short, strictly enforced deadline applies. Always check the current period before acting, as specific limitation periods depend on the facts.
Is it enough if only one conspirator knows all the facts?
All conspirators should be aware of the essential facts underlying the scheme. There are subtle nuances, so seek legal advice on your position.
Can interim injunctions be obtained in conspiracy cases?
Yes. Injunctions are commonly used to freeze assets, preserve evidence, or restrain ongoing harm before the final judgment.
Is conspiracy easier to prove than inducing breach of contract?
Not necessarily. Each tort has unique evidential hurdles. Your legal strategy depends on the evidence, the nature of wrongdoing, and your objectives.
