A non-compete clause is enforceable in Singapore only if it passes a two-stage test: the employer must show a legitimate proprietary interest the clause protects, and the restraint must be reasonable between the parties and in the public interest. That framework was set by the Court of Appeal in Man Financial (S) Pte Ltd v Wong Bark Chuan David [2007] SGCA 53, and it means a large share of the non-competes sitting in standard Singapore employment contracts would not survive a courtroom.
I’m Roy. I’m an Associate Director at A.W. Law LLC, and in my employment disputes practice I read these clauses for two kinds of people: employees who’ve received a warning letter, and employers wondering why the clause they copied from a template won’t hold. Both conversations start in the same place.
The starting point: restraints are void
Singapore law starts from freedom to work. A clause restraining a former employee from earning a living in their trade is a restraint of trade, and restraints are void unless justified. The burden sits on the employer, not you. That single fact reframes most disputes: the question is never “did you sign it” (you did), it’s “can they justify it”.
The justification test from Man Financial v Wong Bark Chuan David [2007] SGCA 53 (also reported at [2008] 1 SLR(R) 663) has two stages:
- A legitimate proprietary interest. Something of the employer’s that the law protects.
- Reasonableness, both between the parties and in the public interest.
Fail either stage and the clause is unenforceable.
Stage one: what interests count
The recognised interests are narrow:
- Trade secrets and confidential information. Real ones: formulas, pricing models, unreleased plans. Not general skill and experience you built on the job, which you’re free to take with you.
- Trade connections. The customer relationships you controlled, where you were effectively the face of the business to those clients.
- A stable, trained workforce. Recognised in Man Financial itself, typically underpinning non-solicitation of colleagues.
Two traps for employers here. Wanting to blunt competition is not an interest; and where a separate confidentiality clause already covers the employer’s information, the non-compete must protect something over and above it, or stage one fails outright. Plenty of contracts have both clauses and flunk for exactly that reason.
Stage two: reasonableness
If an interest exists, the restraint must go no further than needed to protect it. Courts weigh:
| Factor | The question asked |
|---|---|
| Duration | Is 12 months needed, or would 3 protect the interest? |
| Geography | Singapore only, or an unjustified worldwide ban? |
| Scope of activities | The role you actually did, or the whole industry? |
| Your seniority and access | Did you actually hold the secrets or the client book? |
The clause is measured as drafted, not as the employer later wishes it read. And Singapore courts will not rewrite an overbroad clause into a fair one. The most a court does is apply the blue pencil: strike severable words and enforce a clean remainder, if one exists. Drafting greed is fatal, which is why the widest clauses are often the safest to be on the receiving end of.
If you’ve received a warning letter
The sequence I recommend to employees:
- Don’t respond same-day. Nothing in these letters requires a reflex reply, and your first response frames the dispute.
- Gather your contract and the settlement paperwork, if you were retrenched or resigned with a package. Check whether the restraint was in the original contract, added later without fresh consideration, or bought in the settlement.
- Assess the clause against the two stages above, ideally with a lawyer who does this regularly. Most letters overstate the clause’s strength.
- Mind the confidential information separately. Even where the non-compete fails, taking documents, client lists, or files is a different breach, in the same territory as a breach of contract claim, and it’s the fastest way to hand your ex-employer a real case. Take nothing.
For employers, the mirror advice: draft narrow, tie the clause to a named interest, and treat the injunction route as expensive and uncertain, because it is. Often a tighter contract does more than a wider one.
The honest part
In my experience, most non-compete disputes in Singapore never reach a judgment. They resolve on the strength of the first two letters: one side’s clause is overbroad, the other side can’t afford to test it, and a negotiated landing (a shorter sit-out, a carve-out for the new role, a non-solicitation promise instead) settles it. Knowing where your clause actually sits on the enforceability spectrum is what determines who concedes what.
What to do next
If you’re weighing a move, get the clause read before you resign; the advice often changes the timing, the announcement, or what you say in the exit interview. If a letter has already arrived, bring it with your contract and settlement documents.
