Restraint of Trade vs Non-Compete in South Africa
Why the South African "restraint of trade" is different from the American "non-compete"
Restraint of Trade vs Non-Compete in South Africa — what's the difference?
A restraint of trade is the South African common-law instrument — prima facie valid, enforceable unless the employee proves unreasonableness on the Basson v Chilwan test. A non-compete is the US label — often invalid without consideration, blanket-banned in some states, and frequently imported by mistake into SA contracts via foreign templates.

The two options at a glance
Restraint of Trade (SA common law)
SA common law
A Restraint of Trade is the South African common-law mechanism by which an employer restricts a former employee's post-termination competitive conduct to protect identifiable interests — trade connections (customer goodwill and client relationships) and trade secrets (confidential information with commercial value). Rooted in Magna Alloys v Ellis 1984 (4) SA 874 (A), which overturned the earlier presumption of invalidity, a restraint is prima facie valid and enforceable. The employee bears the onus of proving unreasonableness on the four-part test in Basson v Chilwan 1993 (3) SA 742 (A), further refined in Reddy v Siemens 2007 (2) SA 486 (SCA). Scope, geography, and duration must be reasonable; typical durations are 6 to 24 months.
When to use
Use in all SA employment contracts where the employee has access to customer relationships, pricing, methodology, client lists, or proprietary technical information. Tailor the scope to the role — a receptionist does not need a 24-month national restraint; a senior salesperson usually does. Always recite the protectable interests in the clause itself so the court can see what is being protected.
Non-Compete (US-style)
Foreign
A Non-Compete is the US-law label for a post-termination competitive restriction. US enforceability is state-by-state and generally more restrictive than SA: California (Bus & Prof Code s.16600) voids non-competes outright for employees; Minnesota and Oklahoma similarly; the FTC's 2024 rule attempted a federal ban (currently subject to ongoing litigation). Where non-competes are enforceable (most other states, notably Texas, Florida, New York subject to statutory limits), they typically require fresh consideration, a narrow geographic scope, and a duration generally under 12 months. The label often appears in SA contracts imported from US parent-company templates — which creates enforceability gaps when SA courts apply Basson v Chilwan to a clause never drafted with SA common law in mind.
When to use
Only where the governing law is genuinely a US state and the employee operates under that law. In SA operations, use a restraint of trade drafted for SA common law. A "non-compete" label on a SA employment contract is a red flag that the template has not been localised.
Summary
South African and US law treat post-termination restrictions on competition very differently, and contracts that mix the two frameworks often fail. Under SA common law as articulated in Magna Alloys and Research (SA) (Pty) Ltd v Ellis 1984 (4) SA 874 (A), a restraint of trade is prima facie valid; the onus to prove unreasonableness lies on the employee. The test in Basson v Chilwan 1993 (3) SA 742 (A), refined in Reddy v Siemens Telecommunications (Pty) Ltd 2007 (2) SA 486 (SCA), asks four questions: does the former employer have a protectable interest; does the restraint prejudice the employee beyond what is needed to protect that interest; is there a broader public interest; and are there any other relevant factors. Reasonable scope, geography, and duration (ordinarily 6-24 months) are usually enforced. The US "non-compete" is a statutory or state-by-state common-law doctrine with no equivalent prima facie validity — many states (California, FTC guidance, Minnesota) ban them, others require consideration or a narrow scope. Using a US template in SA can create drafting defects (missing protectable-interest recitals, overbroad geography, no Basson v Chilwan hook) that weaken enforceability on a SA court application.

What you need to know
The Basson v Chilwan test — how SA courts decide
The enforceability of an SA restraint rests on the Basson v Chilwan 1993 (3) SA 742 (A) test, later clarified in Reddy v Siemens Telecommunications (Pty) Ltd 2007 (2) SA 486 (SCA). The court asks four questions. First, is there an interest deserving of protection? The two recognised categories are (a) trade connections — customer goodwill and the hold of the employee over the employer\'s client base; and (b) trade secrets — confidential information with commercial value not in the public domain. Generalised skills, experience, and know-how acquired on the job are not protectable.
Second, is that interest being prejudiced by the former employee? The employer must demonstrate that the employee has accessed and could use the protectable interest to harm the former employer. Mere possibility is usually insufficient; actual or reasonably apprehended harm is the test.
Third, weighing the protectable interest against the employee\'s right to work, is the restraint reasonable in scope, geography, and duration? Reasonable scope is tied to the protectable interest — a national restraint for a regional sales representative is unreasonable; a 24-month global restraint for a junior engineer is unreasonable. Typical upheld restraints sit at 6 to 12 months for junior roles, 12 to 24 months for senior roles with meaningful client relationships or trade-secret exposure.
Fourth, is there a broader public interest against enforcement? Scarcity of skills, regulatory context, and social utility can weigh against enforcement. In Reddy v Siemens the SCA emphasised that the court should not "blue-pencil" overbroad provisions if the employer could not have drafted more narrowly in the first place — an important drafting lesson.
Why US "non-compete" templates fail in SA
US non-compete clauses are frequently imported into SA contracts through parent-company templates, SaaS-provider standard forms, or cross-border investor documents. The typical drafting defects: (a) no recital of the SA protectable interests — trade connections and trade secrets — because the US template speaks of "legitimate business interests" in general; (b) geographic scope tied to a US state or a generic "United States" area, which is over-inclusive for an SA employee; (c) duration set at the US state\'s maximum (often 24 months) without regard to the SA reasonableness test; (d) missing consideration clause where the restraint is introduced mid-employment without a fresh benefit; (e) governing-law clause pointing to a US state, which creates conflict-of-law complications because SA courts apply SA common law to restraints of SA-resident employees regardless of the chosen forum.
When such a clause is put to a SA court on interdict, the court applies Basson v Chilwan and often finds the clause unreasonable as drafted. The Reddy v Siemens approach ("do not blue-pencil what the employer should have drafted narrowly") then risks total unenforceability rather than partial. The remedial response is to replace the US clause with a SA-drafted restraint before the employee leaves — not to litigate an imported clause.
Where the employee genuinely works in a US state and the contract is governed by that state\'s law, the US non-compete analysis applies. For SA-resident employees, an SA restraint of trade is the correct instrument regardless of the parent company\'s origin.
Drafting a restraint that will actually be enforced
An enforceable SA restraint should do five things. First, recite the protectable interests expressly — "the Company has developed over [X] years a body of confidential technical know-how, including [Y]; the Company\'s customer relationships in [Z] represent material goodwill built at material cost; the Employee has access to both in the course of employment". The recital gives the court a clear view of what is being protected.
Second, define the restricted activity precisely — "the Employee shall not, during the Restraint Period and within the Restraint Area, solicit or accept business from any Customer with whom the Employee had material contact in the [12] months before termination, or engage in [defined competitive activity] on behalf of any Competitor". Avoid generic "compete with the Company" wording.
Third, tailor scope, geography, and duration to the protectable interest. A typical formulation is stepped: a non-solicitation of customers and employees (24 months), a non-compete in the defined area (12 months), a confidentiality obligation (perpetual for trade secrets). The stepped structure gives the court the option to enforce the narrower prohibitions even if the broadest is read down.
Fourth, provide consideration where the restraint is introduced mid-employment — a bonus, a share option, a retention payment. SA law does not strictly require fresh consideration for an enforceable restraint, but it removes one attack angle.
Fifth, include a severability clause and a narrowing-down clause — "if any provision is unenforceable as drafted, it shall be enforceable to the maximum extent permitted by law". In Reddy v Siemens the SCA declined to blue-pencil, but SA courts will generally respect a well-drafted narrowing-down clause where the overbreadth is marginal.
In South Africa the restraint is valid until the employee proves otherwise. In the US the non-compete is often invalid until the employer proves otherwise. Contracts that import the US idiom into an SA workplace usually lose on both fronts.

Frequently asked questions
How long is a reasonable restraint of trade in South Africa?
There is no statutory maximum — duration is tested for reasonableness against the protectable interest under Basson v Chilwan. In practice the courts uphold 6 to 12 months for junior roles with limited client contact, 12 to 24 months for senior roles with meaningful client relationships or trade-secret access, and occasionally longer for truly senior executives with unique strategic knowledge. Restraints beyond 24 months face significant scepticism and require strong justification. The duration must match the "fade period" during which the protectable interest remains at risk — for fast-moving sectors (tech, fintech) that fade is shorter; for long-cycle industries (mining, pharmaceuticals) it is longer. A 36-month software sales restraint will usually fail; a 24-month restraint for a head of clinical research might be upheld. Drafters should pitch duration at the shortest period consistent with the protectable interest — overreach invites the court to read the whole clause down.
Is a restraint of trade enforceable without fresh consideration?
Yes, South African common law does not require fresh consideration for a restraint to be enforceable. The employee's employment and remuneration are treated as sufficient consideration. This contrasts sharply with many US states, where a mid-employment non-compete without a new benefit is often void. However, providing consideration strengthens the enforceability argument because it closes off the "unfair bargain" angle and demonstrates that the parties treated the restraint as a negotiated bargain rather than an imposition. Common consideration mechanisms include a retention bonus at signing, an uplift in share options, a specific restraint payment (sometimes on termination, sometimes upfront), or enhanced severance. In Reddy v Siemens the SCA noted that consideration was relevant to but not determinative of reasonableness. Best practice for senior roles is to couple the restraint with a clearly identified benefit, reducing the grounds on which the employee can later argue unreasonableness.
Can a SA court blue-pencil an overbroad restraint?
SA courts do partial enforcement — reading down an unreasonable provision to what is reasonable — but they do so cautiously. In Reddy v Siemens 2007 (2) SA 486 (SCA) the court warned against rescuing restraints that were overbroad as drafted, particularly where the employer had the resources to draft more narrowly and chose not to. The court may sever clearly separable provisions (a non-solicitation and a non-compete can be treated separately if drafted as separate clauses), and may narrow geographic or temporal scope where the contract supports it, but will not rewrite a clause to produce a reasonable restraint from an unreasonable one. The practical lesson is to draft restraints as a series of tiered, separately enforceable obligations (non-solicitation of customers, non-solicitation of employees, non-compete in a defined area, confidentiality) so that the court can enforce what it finds reasonable and set aside what it does not. A monolithic "shall not compete anywhere in the world for five years" clause is vulnerable to total invalidation.
Does a restraint bind an independent contractor?
Yes — the Basson v Chilwan analysis applies to restraints between any two contracting parties, not only to employer-employee relationships. Independent contractors, agents, distributors, and franchisees can all be subject to enforceable restraints where the same four-part test is met. The analysis is sometimes more favourable to the restrainor in commercial relationships than in employment because the contractor typically has more bargaining power and the public-interest leg of Basson weighs differently. However, the protectable interests must still be identified — a restraint on a contractor with no customer contact and no trade-secret access is as vulnerable as one on a junior employee. In franchise and distribution agreements, post-termination non-compete clauses are routine and enforceable where the franchisor/principal has a genuine protectable interest in customer goodwill built by the franchisee/distributor during the term.
What happens if the contract labels the clause "non-compete" rather than "restraint of trade"?
The label does not determine enforceability — SA courts look at substance, not form. A clause titled "Non-Compete" that restricts post-termination competition in an SA contract is tested against Basson v Chilwan just as a clause titled "Restraint of Trade" is. However, the label is a strong signal that the drafter worked from a non-SA template and may not have built the SA-law foundations into the clause. Common defects in "non-compete"-labelled SA clauses: no recital of protectable interests, generic "legitimate business interest" language, over-inclusive geography, no tailoring to the role, governing-law clauses pointing to a US state. The prudent course for any SA operation using a foreign-template employment contract is to have it reviewed by SA counsel and rewritten as a restraint of trade with explicit Basson v Chilwan hooks. Enforcing a poorly localised "non-compete" on interdict is difficult and often embarrassing.
Can I get an urgent interdict to enforce a restraint of trade?
Yes. Restraint-of-trade enforcement is typically sought by way of urgent interim interdict in the High Court. The applicant must satisfy the Setlogelo v Setlogelo 1914 AD 221 requirements: a prima facie right (demonstrated by the restraint clause and the protectable interests), a well-grounded apprehension of harm (the employee has joined a competitor or is about to), the balance of convenience favours the applicant, and no alternative satisfactory remedy. The respondent resists on Basson v Chilwan grounds — the restraint is unreasonable, the protectable interest does not exist, or the scope is disproportionate. SA courts routinely grant interim relief on restraint matters when the clause is well-drafted and the facts support a real risk. Turnaround can be fast: urgent applications heard within weeks, and interim relief often granted pending a full hearing on the main interdict. Costs against the losing party are usual, which both encourages enforcement and disciplines employees considering breach.
