NDA in Hong Kong: Template, Key Clauses and Local Law (2026)
What an NDA in Hong Kong is A non-disclosure agreement in Hong Kong is a contract in which one or both parties promise to keep shared information secret and to use it only for an agreed purpose. It can be one way or mutual. Hong Kong follows English common law, so an NDA is binding as a contract and is generally enforceable when its terms are clear and its scope and duration are reasonable. It also sits alongside an equitable duty of confidence that can arise even without a written agreement, so a good NDA adds certainty, defined scope and specific remedies to a protection that already exists in part. This page is general information, not legal advice. For a deal that matters, have a Hong Kong lawyer confirm the drafting. ## What local law requires Contract plus equity. As a contract, the NDA is enforced on its terms. Separately, the equitable duty of confidence can arise in certain circumstances. The classic test from Coco v A N Clark asks whether the information has the necessary quality of confidence and is not in the public domain, whether it was shared in circumstances importing an obligation of confidence, and whether there has been unauthorized use to the discloser's detriment. A written NDA makes all three easier to prove. Reasonable scope. Hong Kong courts enforce NDAs that are clear and reasonable. A vague or unreasonably wide agreement is harder to enforce. In the employment context in particular, courts have declined to enforce overbroad confidentiality clauses that in reality operate as non-competes. So draft the scope, the definition of confidential information, and the duration to be no wider than the legitimate interest you are protecting. Employees and former employees. During employment, an employee owes an implied duty of fidelity. After employment ends, only genuine trade secrets are protected automatically; ordinary confidential information needs an express written obligation. If you want protection to continue after someone leaves, say so clearly and keep it reasonable. Personal data. Where the confidential information includes personal data, the Personal Data (Privacy) Ordinance (Cap. 486) applies. Add obligations to handle that data in line with Cap. 486. Remedies and limitation. An NDA commonly provides for injunctions as well as damages, because stopping disclosure matters more than compensation after the fact. Contract claims are generally subject to a six-year limitation period under the Limitation Ordinance (Cap. 347). ## A simple mutual NDA structure you can adapt ```
NON-DISCLOSURE AGREEMENT (Hong Kong) Between [Party A, address] and [Party B, address] 1. PURPOSE The parties will share information to [describe the purpose]. 2.

Personal data is handled in line with the Personal Data (Privacy) Ordinance (Cap. 486). 3. OBLIGATIONS Each party keeps the other's confidential information secret, uses it only for the Purpose, and limits access to people who need it and are bound by confidentiality. 4.

Governed by the laws of Hong Kong. Date: [date] Party A ______________ Party B ______________
- A confidentiality clause that in substance stops a former employee from working, which courts may refuse to enforce.
- No personal data clause where the information includes personal data.
- No injunction right, leaving damages as the only remedy after disclosure.
- No governing law or forum. ## A short checklist before you sign - Define a narrow purpose and keep the definition of confidential information clear and, where possible, marked.
- Match the duration to the sensitivity of the information, and protect genuine trade secrets for as long as they stay secret.
- Keep any post-employment restriction reasonable, so courts do not treat it as a disguised non-compete.
- Add a Personal Data (Privacy) Ordinance (Cap. 486) clause where personal data is in scope.
- Provide for injunctive relief as well as damages, so a threatened breach can be stopped quickly.
- Set the governing law and forum, and keep the six-year contract limitation period in mind.
- For a deal that matters, have a Hong Kong lawyer confirm the drafting. ## Where this sits with your other contracts An NDA is usually signed at the start of a conversation and then set aside until something goes wrong. By then the questions are practical: which version did we sign, what was the purpose, when does it expire, and is the scope reasonable enough to enforce. Keeping the NDA findable and current is the real work. That is the same problem across every contract a company signs, in each place it operates. Drafting from a reliable structure, catching a definition that is too broad or a clause that will not hold locally, editing a term in plain language, and holding every version with its date can live in one AI workspace tuned to how your company contracts. [Adira](https://adiralaw.com) is built around that single workspace idea. It is deepest in Indian corporate law today, and Hong Kong-specific depth is on its roadmap rather than a finished feature, so a Hong Kong NDA still needs the law above and local advice. The idea to keep is that contracts are easier to trust when drafting, review, editing and version history live in one place.
Frequently asked questions
- Are NDAs enforceable in Hong Kong?
- Yes. An NDA is binding as a contract and is generally enforceable when its terms are clear and its scope and duration are reasonable. It also sits alongside an equitable duty of confidence that can arise even without a written agreement, so a good NDA adds certainty, defined scope and specific remedies. This is general information, not legal advice.
- What is the Coco v Clark test?
- It is the classic common-law test for breach of confidence. It asks whether the information has the necessary quality of confidence and is not in the public domain, whether it was shared in circumstances importing an obligation of confidence, and whether there has been unauthorized use to the discloser's detriment. A written NDA makes all three easier to prove.
- Does a Hong Kong NDA protect information after an employee leaves?
- During employment an employee owes an implied duty of fidelity. After employment ends, only genuine trade secrets are protected automatically; ordinary confidential information needs an express written obligation. Courts have declined to enforce overbroad clauses that in reality operate as non-competes, so keep any post-employment restriction reasonable.
- What if the confidential information includes personal data?
- The Personal Data (Privacy) Ordinance (Cap. 486) applies where confidential information includes personal data. Add obligations to handle that data in line with Cap. 486 alongside the confidentiality terms.
- Should a Hong Kong NDA include an injunction clause?
- Yes, it is common and sensible to provide for injunctive relief as well as damages, because stopping disclosure matters more than compensation after the fact. Contract claims are generally subject to a six-year limitation period under the Limitation Ordinance.
