NDAs Are One of the Most Common — and Most Misunderstood — Contracts in SA
Non-disclosure agreements (NDAs) are signed daily across South Africa. Before business discussions, before sharing trade secrets, before hiring employees with access to sensitive information. But many NDAs are poorly drafted and wouldn't survive a legal challenge.
Under South African common law, NDAs are enforceable contracts — provided they meet certain requirements. Here's what you need to know.
What Makes an NDA Legally Enforceable in South Africa?
An NDA is a contract, so it must meet the basic requirements of a valid contract under SA law:
1. Consensus (agreement) — both parties must genuinely agree to the terms
2. Capacity — both parties must have legal capacity to contract
3. Legality — the purpose must be lawful
4. Possibility of performance — the obligations must be capable of being performed
5. Formalities — while NDAs don't legally require written form, an oral NDA is virtually impossible to enforce (you'd have to prove what was agreed)
The 8 Essential Clauses Every SA NDA Must Include
1. Definition of Confidential Information
Why it matters: If you don't define what's confidential, you can't prove a breach.
Best practice: Be specific. Rather than "all information shared between the parties," list categories: financial data, customer lists, business plans, technical specifications, trade secrets, pricing structures.
Common mistake: Defining confidential information so broadly that it includes publicly available information. Courts will not enforce NDA obligations for information that is already in the public domain.
2. Obligations of the Receiving Party
What to include:
- Not to disclose confidential information to any third party without prior written consent
- To use the information only for the stated purpose
- To take reasonable steps to protect the confidentiality (at least the same level of care as for their own confidential information)
- To limit internal disclosure to employees/agents who need to know
3. Permitted Disclosures
What to include: Circumstances where disclosure is allowed without breach:
- Information already in the public domain (not through breach of the NDA)
- Information independently developed by the receiving party
- Information received from a third party who is not bound by confidentiality
- Disclosure required by law or court order (but with an obligation to notify the disclosing party first)
4. Duration of Confidentiality
What to include: How long the confidentiality obligation lasts.
SA law position: There is no statutory limit. Courts will enforce reasonable durations. For commercial NDAs, 2-5 years is standard. For trade secrets, perpetual confidentiality obligations are common and generally enforceable.
Red flag: No duration specified at all. This creates uncertainty and may be challenged as unreasonable.
5. Return or Destruction of Information
What to include: What happens to confidential information when the NDA expires or terminates. Typically, the receiving party must return all documents and delete all electronic copies, and certify in writing that they've done so.
6. Remedies for Breach
What to include: The disclosing party is entitled to seek an interdict (injunction) and damages.
SA law context: South African courts can grant interdicts to prevent ongoing or threatened breaches of NDAs. This is often more valuable than damages, because once confidential information is disclosed, the damage is done.
Include an acknowledgment that damages may be difficult to quantify and that the disclosing party is entitled to urgent interim relief without proving actual damages.
7. Non-Solicitation (if applicable)
What to include: If relevant, a clause preventing the receiving party from soliciting the disclosing party's employees, clients, or suppliers using confidential information.
SA law position: Non-solicitation clauses are enforceable if reasonable in scope and duration. A 12-24 month non-solicitation period is typically considered reasonable.
8. Governing Law and Jurisdiction
What to include: That the NDA is governed by South African law and subject to the jurisdiction of South African courts.
Why it matters: For international NDAs, this prevents disputes from being heard in foreign courts under unfamiliar legal systems.
Common NDA Mistakes in South Africa
1. Too broad — defining everything as confidential, including publicly available information
2. No duration — leaving confidentiality obligations open-ended without specifying a term
3. One-sided only — failing to make the NDA mutual when both parties are sharing information
4. No remedies clause — not specifying what happens if the NDA is breached
5. No carve-outs — failing to exclude legally compelled disclosures
6. Signed by the wrong person — someone without authority to bind the company
When NDAs Don't Work
An NDA cannot protect you if:
- The information is already publicly known
- The information was independently developed by the other party
- You failed to take your own reasonable steps to keep it confidential (e.g., posting trade secrets on an unsecured website)
- The clause is so broad that it's unreasonable and a court refuses to enforce it
