Every company runs on information that would be valuable in the wrong hands: client lists, pricing models, supplier terms, product formulae, source code and business plans. When a departing employee, a former joint-venture partner or a competitor misuses that information, the company’s most direct remedy is often a claim for breach of confidence.
Breach of confidence is a powerful and flexible tool in Singapore law. It can protect information that is not registered as any formal intellectual property right, and it can support an urgent injunction to stop misuse before the damage spreads. This guide explains what the claim covers, the legal test the Singapore courts apply, the remedies available and the practical steps to take when you suspect your confidential information has been taken.
What breach of confidence protects
A breach of confidence claim protects confidential information from unauthorised use or disclosure. Unlike a trade mark or patent, there is no registration and no register to search. Protection arises from the nature of the information and the circumstances in which it was received.
Typical examples include customer databases, tender pricing, manufacturing know-how, unpublished financial data and strategic plans. The information does not need to be complex or technical. What matters is that it is not public knowledge and that it has the necessary quality of confidence.
The legal basis in Singapore
Breach of confidence in Singapore is a common law action rather than a creature of statute. The traditional elements are that the information had the necessary quality of confidence, that it was communicated in circumstances importing an obligation of confidence, and that there was unauthorised use to the detriment of the party who confided it.
The modern Singapore position was reshaped by the Court of Appeal in I-Admin (Singapore) Pte Ltd v Hong Ying Ting [2020] 1 SLR 1130. The court adopted a modified approach that better protects a claimant’s interest in preventing wrongful loss. Once the information has the quality of confidence and was accessed in circumstances importing an obligation of confidence, an obligation is presumed to have been breached where the defendant’s conscience was affected, and the burden shifts to the defendant to show that its conscience was clean. This makes it easier for an aggrieved company to establish a breach where an employee has copied or taken data on the way out.
Breach of confidence compared to other protections
Confidentiality overlaps with, but is distinct from, other rights.
Versus restraint of trade
A restraint of trade clause restricts what an ex-employee may do. A breach of confidence claim restrains the misuse of specific information and does not depend on a valid non-compete. The two often run together, but the confidence claim can succeed even where a non-compete fails.
Versus registered intellectual property
A registered trade mark or patent gives a monopoly recorded on a public register. Confidence protects secret information for as long as it stays secret. Once the information is genuinely public, the protection is lost. Details on formal registration are available from the Intellectual Property Office of Singapore.
Who can bring a claim
Any person or company that owns or controls the confidential information and has suffered, or faces, unauthorised use may sue. In practice claimants are usually employers acting against former staff, businesses acting against former partners or contractors, and companies acting against competitors who have received leaked information. A recipient who knows or ought to know that information was disclosed in breach of confidence can also be liable, which is why the new employer is frequently joined to the action.
Remedies for breach of confidence
The Singapore courts can grant a range of remedies. The most important in urgent cases is the injunction, restraining further use or disclosure of the information. Where an employee has used confidential information to get a head start, the court may grant a springboard injunction to neutralise that unfair advantage for a limited period.
Financial remedies include damages for loss suffered or an account of the profits the defendant made from the misuse. The court can also order delivery up or destruction of documents and copies, including electronic copies.

Step-by-step: acting on a suspected breach
Speed and evidence preservation are decisive. A typical sequence is as follows.
1. Identify precisely what information has been taken or misused and confirm it is genuinely confidential and not public. 2. Preserve the evidence, including device logs, email records, download histories and access records, before they are overwritten. 3. Review the contracts and confidentiality policies that applied to the person involved. 4. Send a letter of demand seeking immediate cessation, delivery up and written undertakings. 5. If undertakings are refused or the risk is urgent, apply to the High Court for an injunction supported by an affidavit. 6. Pursue the claim to trial or negotiate a settlement.
Documents you will typically need
| Document | Purpose |
|---|---|
| Confidentiality or employment agreement | Shows the obligation of confidence in writing |
| Description of the information | Identifies exactly what is confidential |
| Evidence of access and misuse | System logs, emails, USB and download records |
| Letter of demand | Seeks undertakings and preserves your costs position |
| Supporting affidavit | Sets out the facts for the injunction application |
Timeline and indicative costs
| Stage | Indicative timing | Indicative cost |
|---|---|---|
| Evidence preservation and demand | Days to 2 weeks | Lower |
| Interim injunction application | Days to a few weeks (urgent) | Moderate to high |
| Trial and financial remedies | Several months to over a year | Substantial |
The figures are indicative only and depend on urgency and complexity. Acting within days of discovery, rather than weeks, materially improves the prospects of an injunction.
What happens after the order
If an injunction is granted, the defendant must stop using the information and comply with any delivery-up order, or risk contempt of court. A springboard injunction will lapse once the unfair advantage has been neutralised. Prevention remains far cheaper than litigation: clear confidentiality clauses in employment contracts, controlled system access, and disciplined use of secure documentation practices reduce the risk of a breach in the first place.
Frequently asked questions
Do I need a signed NDA to sue for breach of confidence?
No. An obligation of confidence can arise from the circumstances in which information was received, even without a written agreement. A signed NDA or confidentiality clause makes the claim far easier to prove.
What if the information is partly public?
Information that is genuinely in the public domain is not confidential. However, a confidential compilation or a specific combination of otherwise public facts can still attract protection.
Can I sue the new employer as well as the ex-employee?
Often yes. A recipient who knew or ought to have known that the information was disclosed in breach of confidence can be liable, which is why claimants frequently name the new employer too.
How quickly must I act?
As quickly as possible. Delay weakens the case for urgent relief and gives the information more time to spread. Preserve evidence immediately and seek advice within days.
