How to Claim for Misuse of Confidential Information

Misuse of confidential information can undermine a business's competitive position, damage reputation, or undermine strategic plans. In commercial contexts in England and Wales, the law recognises claims for misuse of confidential information as a civil wrong that can give rise to remedies such as injunctions, damages and accounts of profits. These claims apply where confidential material is shared in circumstances that create a duty of confidence and is then used or disclosed without permission. This article explains how to identify when misuse has occurred, the legal basis for a claim, the steps businesses can take to pursue a claim, remedies available from tribunals or courts, time limits and practical considerations.

What Counts as Misuse of Confidential Information?

Confidential information is data or knowledge that:

• Has quality of confidence – meaning it is not public knowledge and has commercial value;
• Is shared in circumstances that attract a duty of confidence, either because of a contract (such as a non‑disclosure agreement) or because of the nature of the relationship (such as business partners or employees);
• Is used or disclosed without authorisation and to the detriment of the owner.

A duty of confidence can arise expressly under a confidentiality clause in a contract or implied by the surrounding circumstances and relationship between the parties. For example, when sensitive business strategy, trade secrets, financial data or client lists are shared, a reasonable person in the recipient's shoes would understand that the information should be treated confidentially.

Legal Basis for Claims in England and Wales

Unlike criminal offences, misuse of confidential information is addressed through civil law under the equitable doctrine of breach of confidence. This doctrine allows a claimant to seek remedies when confidential information is disclosed or used without authorisation. A similar legal foundation applies whether the duty arises from contract or from common law obligations.

Key elements of a misuse or breach of confidence claim are:

1. A duty of confidence existed – through contract, implied circumstances, or special relationship.
2. The information was confidential – not trivial and not generally available in the public domain.
3. There was unauthorised use or disclosure – whether intentional or negligent.
4. Detriment or misuse is shown – although in some equitable claims, mere unauthorised use may suffice to establish liability.

Importantly, courts have clarified that businesses do not always have to prove actual financial loss if confidential information was deliberately and surreptitiously taken, copied or stored for competing purposes. In such cases, the mere unauthorised handling of the confidential data can establish a breach of confidence.

Preparing to Make a Claim

1. Identify and Document the Confidential Information

Begin by identifying precisely what information was shared, why it was confidential, and in what context it was disclosed. Good documentation might include:

• Copies of the information itself (e.g., strategy documents, technical data);
• Contracts or non‑disclosure agreements specifying confidentiality obligations;
• Notes of meetings or communications where the information was disclosed;
• Evidence that the information was not publicly accessible before and retains commercial value.

The more clearly the information's confidential nature and origins are documented, the stronger the claim's foundation.

2. Confirm the Duty of Confidence

If a written confidentiality agreement exists, the duty of confidence may be straightforward. If not, it may be necessary to show that the circumstances of the disclosure implied a duty, for example because of a close commercial relationship or explicit instructions that the information was confidential. A reasonable person test is often applied: would a reasonable recipient have understood that the material was confidential?

Steps to Pursue a Claim

Step 1: Raise the Issue Informally

Before formal legal proceedings, businesses often contact the offending party to raise concerns. A cease‑and‑desist letter from legal advisers summarising the confidential information, the duty of confidence, and the alleged misuse can prompt early resolution or negotiation of a settlement.

Step 2: Consider Urgent Court Orders

If confidential information is about to be misused or disclosed, an early application for an injunction can prevent further harm. The court can grant:

• Interim injunctions to preserve the status quo while the case proceeds;
• Springboard injunctions to remove any unfair competitive advantage gained by misuse of confidential information. These are often relevant where the defendant has obtained a head‑start in the market due to wrongful use.

If confidential information has already been used or disclosed, injunctions may be of limited use, but can still prevent further misuse.

Step 3: Issue a Civil Claim

If negotiation is unsuccessful, a formal claim for misuse of confidential information can be issued in the civil courts of England and Wales. The claimant must set out:

• The facts of how the confidential information was shared;
• The duty of confidence that applied;
• How the information was misused or disclosed without authorisation;
• The harm suffered or the competitive disadvantage experienced.

Proceedings usually begin in the County Court for lower value or less complex claims, or in the High Court for significant commercial disputes.

Remedies Available from the Courts

If a court or tribunal finds that confidential information has been misused, several remedies are available:

Injunctions

An injunction may restrain the defendant from continuing to use or disclose confidential information. This is particularly important to prevent ongoing or future misuse.

Damages

Damages are monetary awards intended to compensate the claimant for financial losses caused by the misuse of confidential information. The level of compensation depends on the nature and extent of loss.

Account of Profits

In some cases, instead of (or alongside) damages, a claimant may seek an account of profits. This requires the defendant to pay the profits they have made through wrongful use of the confidential material. Only one of these remedies is usually available in a given claim.

Delivery Up and Destruction

Courts may order that materials containing confidential information be delivered up or destroyed to prevent further misuse, especially where the continued existence of those materials poses ongoing risk to the claimant's business.

It is important to act promptly if seeking equitable remedies like injunctions, as delay may reduce the likelihood of obtaining them. Courts expect timely applications and can refuse injunctive relief if a claimant unreasonably delays.

Time Limits for Claims

Claims for misuse of confidential information are generally subject to the Limitation Act 1980, which allows up to six years from the date of the breach to start a civil claim. The courts typically consider the date when the claimant became aware (or should have reasonably become aware) of the breach. Prompt action is advisable as delays can weaken evidence and lead to dismissal of injunctive relief.

Common Defences and Challenges

Defendants may contest claims by asserting:

• The information was not confidential because it was already in the public domain;
• No duty of confidence existed in the circumstances of disclosure;
• The information was not used or disclosed unauthorisedly;
• Disclosure was justified by public interest or legal obligation.

Each defence requires scrutiny of the facts, and documentary evidence is central to assessing the defendant's position.

Practical Considerations for Businesses

Record Keeping and Information Policies

Strong internal practices for classifying and handling confidential information help demonstrate commercial sensitivity and bolster claims in disputes.

Non‑Disclosure Agreements (NDAs)

Clearly drafted NDAs with detailed definitions of confidential information and explicit terms on use and non‑use strengthen a legal position before a dispute arises.

Early Legal Advice

Misuse of confidential information is a specialised area of law blending contract, equity and commercial litigation. Early consultation with experienced solicitors helps to identify the best course of action and manage procedural requirements such as pre‑action protocols and court filings.

Key Takeaways

To claim for misuse of confidential information in England and Wales, a business must establish that it shared confidential information in circumstances creating a duty of confidence, that the information was not publicly available, and that it was used or disclosed without authorisation. Legal remedies include injunctions to prevent further misuse, damages to compensate for loss, accounts of profits to strip wrongful gains, and orders for delivery up or destruction of confidential materials. Acting promptly, documenting the nature and context of the confidential information and seeking specialist legal advice improves the likelihood of a successful claim.
