Non-compete clauses show up in a lot of Singapore employment contracts, particularly for senior or client-facing roles. Here’s the catch: there’s currently no statute behind them. Unlike the tax rules we usually write about here, restraint of trade law in Singapore is almost entirely judge-made, built on case law over decades. That makes it slower to research and harder to pin down than a provision with a fixed rate or threshold. It also means something a lot of employees don’t realise: signing the clause doesn’t settle the question of whether it actually works as intended.
So if you’re an expat weighing a job offer with a restrictive clause attached, or a business owner trying to protect what you’ve built, here’s where things currently stand.
The starting point: these clauses are presumed invalid
Singapore courts presume a non-compete to be void and unenforceable unless the employer proves otherwise. This isn’t really a matter of contract interpretation so much as public policy: people should generally be free to earn a living, and an employer doesn’t get to take that away just because both sides put their names on a document.
The modern test comes from the Court of Appeal’s decision in Man Financial (S) Pte Ltd v Wong Bark Chuan David (2008). To enforce a restraint of trade clause, the employer has to show two things:
- The clause protects a legitimate proprietary interest, and
- The clause is reasonable, both between the parties and in the interest of the public.
Both parts have to be satisfied. A court finding the clause fair to the two parties who signed it isn’t the end of the inquiry; it separately asks whether enforcing the clause serves the broader interest in keeping the labour market open.
Practically, this means agreeing to a non-compete is not the same as being bound by one. The courts have said so: parties freely entering into a restraint doesn’t save it, since the rule against unreasonable restraints can’t be contracted around.
What counts as a “legitimate interest”
Employers generally rely on one of three interests: trade secrets and confidential information, trade connections with customers or clients, or maintaining a stable, trained workforce.
That last one tends to surprise people. Courts have accepted that a business can have a real interest in not losing trained staff to a competitor, in roughly the same way it protects its customer base. The problem is that this argument almost always needs two things to succeed, and employers usually only manage one: a genuinely small, specialised industry where a trained employee is hard to replace, and evidence the employer actually invested in that specific employee’s expertise, rather than just having them pick up the job the way anyone would.
There’s also a trap worth flagging here. If confidential information is already covered by a separate confidentiality clause in the contract, the employer can’t turn around and use “protecting confidential information” as the justification for the non-compete as well. The non-compete needs to be doing something the confidentiality clause isn’t already doing. Otherwise it’s just a restriction on competition wearing a different label, and courts won’t enforce it.
Shopee Singapore Pte Ltd v Lim Teck Yong (2024) is the clearest recent illustration. Shopee tried to stop a former senior employee from joining ByteDance’s TikTok Shop, partly on the basis that it needed to protect confidential information, but that information was already covered by a separate confidentiality agreement he’d signed. The High Court wasn’t persuaded there was anything left for the non-compete to protect, and separately found the eight-country geographic scope too wide for what the employee’s actual role had been. No injunction. A few months later, MoneySmart Singapore Pte Ltd v Artem Musienko (2024) went the same way: the court rejected the “stable workforce” argument outright, since the digital insurance industry wasn’t small or specialised, and criticised the clause for locking the employee out of an entire product category he’d never worked in.
Even with a legitimate interest established, the clause still has to be reasonable on scope, geography and duration. A handful of patterns keep turning up in the case law. Geography should reflect where the employee actually had customer contact, not wherever the employer someday hopes to expand into. Applying an identical clause to every employee regardless of seniority is a red flag on its own, since it suggests the real goal was blocking competition rather than protecting anything specific. And a clause with no end date is automatically unreasonable; courts can delete offending words from a clause (this is called the “blue pencil” test), but they won’t insert a duration nobody agreed to.
It’s not all one-sided, though. In Tan Kok Yong Steve v Itochu Singapore Pte Ltd (2018), a two-year non-compete survived because it was drafted tightly: limited to the specific product line the employee had traded, limited to the countries where he actually had customer relationships, and pegged to how long it typically took to build trade connections in that industry. Precision holds up. Broad language usually doesn’t.
Business owners: a more relaxed standard applies
Selling or buying a business is a different story from hiring an employee, and the courts know it.
CLAAS Medical Centre Pte Ltd v Ng Boon Ching (2010) lays out why. A doctor sold his aesthetic medicine practice, then tried to reopen a competing clinic down the road. The Court of Appeal took a more forgiving line here than it would in an employment case, for two reasons: a business buyer is paying for something tangible, the goodwill, which loses value fast if the seller can just set up next door; and buyer and seller in a business sale tend to have more equal bargaining power than an employer and employee do.
The three-year, Singapore-wide restriction on the doctor was upheld, longer and broader than most equivalent employment clauses would survive. The court did trim one piece that overreached, a catch-all definition of “aesthetic medicine” that swept in more than what the seller had actually built a reputation in, using the blue pencil test to cut just that phrase and leave the rest standing.
For expats structuring a business sale, joint venture, or shareholders’ agreement, the takeaway is straightforward: a restraint tied to selling a business has real teeth here, more than the same clause would have in an employment contract. Same underlying test, lower bar.
What’s on the horizon
Non-compete clauses have become something of a political issue in Singapore, especially after retrenched employees found themselves still bound by them. The Ministry of Manpower, alongside the labour movement and employer federations, has been drafting Tripartite Guidelines on Restraint of Trade Clauses in Employment Contracts since early 2024. Once released, they’re expected to be non-binding but persuasive, guidance courts and the Ministry can lean on rather than a change to the underlying legal test.
Practical takeaways
If you’re an expat employee: signing a non-compete doesn’t mean you’re stuck with it. Singapore courts strike these down more often than they uphold them. That’s not a guarantee, though, and most of these disputes get fought at the interim injunction stage, where a court only needs a “serious question to be tried,” not a final answer. That can mean months of being kept out of a new job while the case works itself out, even in a matter you’d probably win eventually. Get a clause reviewed before you sign, and again before you assume it won’t hold.
If you’re a business owner hiring staff: a clause built around the specific employee’s role, their real customer contact, and a duration you can actually justify will outlast a generic clause copied across the whole company. If you’re buying or selling a business instead, you have more room to negotiate something meaningful, but you still need to be precise about exactly what you’re protecting.
