Restrictive Covenants in Singapore
Restrictive covenants in Singapore are presumed void unless they protect a legitimate interest and go no further than reasonably necessary. Courts judge them as at the date they were signed and generally will not rewrite them. This guide explains the legal test, the types of restraint, drafting that holds, enforcement steps and the cross-border complications regional businesses face.
Key pointSingapore courts generally sever but do not rewrite an unreasonable restraint, so one broad clause can fail entirely; separate, role-specific covenants are the only reliable way to keep at least some protection.
At a glance
Presumed void
A restraint of trade is prima facie void; the party enforcing it must show a legitimate interest and that the restraint is reasonable.
Man Financial test
The Court of Appeal in Man Financial v Wong Bark Chuan David [2008] confirmed the two-stage legitimate interest and reasonableness approach.
Judged when signed
Reasonableness is assessed at the date the covenant was made, so later conduct by the employee cannot rescue an overly wide clause.
Sever, not rewrite
Courts may strike out offending words under the blue pencil approach but will not redraft, so separate covenants are essential.
Confidentiality as backstop
Under I-Admin v Hong Ying Ting [2020], a modified breach of confidence approach helps employers whose information is taken without consent.

What restrictive covenants in Singapore cover
Restrictive covenants in Singapore are contractual promises that limit what a person may do after leaving a business: working for a competitor, soliciting or dealing with clients, recruiting former colleagues or using confidential information. They appear most often in employment contracts, but also in shareholder agreements, sale and purchase agreements, partnership deeds, consultancy agreements and distribution contracts.
The starting point is unusual. A covenant in restraint of trade is presumed void under Singapore law, and the party relying on it must show that it protects a legitimate interest and goes no further than reasonably necessary. Courts look at the covenant as at the date it was made, not at what the employee later did. A covenant that was too wide when signed will not be saved because the employee's later conduct was plainly unfair.
The practical consequence is that the value of a restraint is decided at the drafting stage. By the time an employee resigns to join a competitor, the employer can only enforce what was properly written years earlier.
The legal test: legitimate interest and reasonableness
Singapore courts apply the common law doctrine of restraint of trade. The leading Court of Appeal decision, Man Financial (S) Pte Ltd v Wong Bark Chuan David [2008] 1 SLR(R) 663, confirmed a two-stage approach. First, the employer must identify a legitimate proprietary interest that the covenant protects. Second, the covenant must be reasonable in the interests of the parties and of the public.
What counts as a legitimate interest
Protection from competition as such is not a legitimate interest. The interests courts have been willing to protect include trade secrets and confidential information, connections with clients and suppliers, and, in appropriate cases, the stability of a trained workforce. The employer must show that the particular employee had access to or influence over that interest. A junior employee with no client contact and no access to sensitive information will rarely be bound by a non-compete.
How reasonableness is assessed
Reasonableness depends on the scope of the activity restrained, the geographic area, the duration, the employee's role and seniority, and whether the employee received anything in return. Each element must be justified by reference to the interest identified. A restraint covering all of Asia for a manager whose clients were in Singapore and Malaysia is likely to fail; so is a two-year restraint where client relationships in the sector refresh within a few months.
Courts generally do not rewrite an unreasonable covenant to make it enforceable. They may sever offending words where the remainder makes sense without adding or changing anything, applying what is often called the blue pencil test. That is why drafting with separate, self-contained restraints is far more effective than one long clause.
| Covenant | What it restricts | Interest usually relied on | Drafting focus |
|---|---|---|---|
| Non-compete | Working for or setting up a competing business | Confidential information that cannot be protected by a confidentiality clause alone | Narrow activity, defined competitors, short period, limited territory |
| Non-solicitation of clients | Approaching clients to take business away | Client connections built at the employer's expense | Limit to clients the employee dealt with in a recent look-back period |
| Non-dealing | Doing business with clients even if they approach the employee | Client connections in relationship-driven sectors | Harder to justify; reserve for senior client-facing roles |
| Non-poaching of staff | Recruiting or enticing former colleagues | Stability of the workforce | Limit to staff of a certain seniority the employee worked with |
| Confidentiality | Using or disclosing confidential information | Trade secrets and confidential information | Define categories; not time-limited for genuine trade secrets |
| Garden leave | Working during notice while still employed | All of the above, during the notice period | Express right to exclude from work; consider offsetting against post-termination restraints |
Employment restraints versus commercial restraints
Courts treat restrictive covenants in Singapore differently depending on context. Employment restraints receive the strictest scrutiny because of the perceived inequality of bargaining power and the importance of allowing people to earn a living. Restraints given by a seller of a business, or between shareholders in a joint venture, are assessed more generously because the parties usually negotiate on more equal terms and the buyer is paying for goodwill that the restraint protects.
That difference matters in practice. A founder who sells a company and stays on as an employee may be bound by both a sale restraint in the share purchase agreement and an employment restraint in the service contract. The sale restraint will often be easier to enforce and can justify a longer period. Draft both deliberately and say which applies to what. Our pages on mergers and acquisitions and shareholder agreements cover the commercial side, and our guide on non-compete clauses in commercial contracts explains how distribution and supply restraints are approached.
Drafting restraints that hold
Well-drafted restrictive covenants in Singapore are tailored, separated and supported by evidence of the interest they protect. The following principles make the difference.
Tailor by role, not by company
Group-wide restraints applied to every employee are the most common reason restraints fail. Create tiers: no post-termination restraint beyond confidentiality for junior staff; client non-solicitation and staff non-poaching for client-facing managers; and a short non-compete only for senior employees with access to strategic information. Record why each tier was set as it was.
Separate the restraints
Draft each restraint as a separate covenant with its own definitions of activity, area and period. If a court strikes down the non-compete, the non-solicitation should survive on its own. Many employers also use alternative periods or areas within a clause, but these step-down structures can raise questions of certainty and should be used carefully.
Define the key terms tightly
Define restricted clients by reference to those the employee dealt with or had confidential information about in a look-back period, often the last 12 months of employment. Define competing business by reference to the products and services the employee was actually involved in. Avoid catch-all definitions that sweep in the entire group's activities worldwide.
Consider consideration and garden leave
A restraint introduced mid-employment needs fresh consideration, such as a promotion, a pay rise or an award. Where a long notice period with garden leave is used, consider offsetting the garden leave period against the post-termination restraint, which helps show overall reasonableness.
Restraint wording should be coordinated with the rest of the employment contract, especially notice, garden leave and the definition of confidential information.
Keep a short file note for each senior hire recording the clients, markets and information the person will handle, and review it at promotion. If you ever need to enforce, that contemporaneous record is often the best evidence that the restraint protected a real interest.
Notice, garden leave and the statutory backdrop
Post-termination restraints work alongside the notice period, and the two should be designed together. The Employment Act 1968 requires notice periods to be the same for both parties and allows either party to end the contract by paying salary in lieu of notice; MOM's termination with notice guidance sets out the default periods where a contract is silent. Senior contracts typically specify longer notice.
During notice, the employee remains employed and owes duties of fidelity. A garden leave clause lets the employer keep the employee away from clients, colleagues and systems while still bound by those duties, which is often the most effective restraint of all because it does not depend on the restraint of trade doctrine. If the employer instead pays in lieu and ends employment early, the employee is released sooner and only the post-termination covenants remain.
A sensible structure for senior roles combines a notice period of three to six months, an express garden leave right, an offset of any garden leave against the non-compete period, and separate non-solicitation and non-poaching covenants. That package is easier to justify as a whole than a long non-compete standing alone.
Fairness matters too. MOM's fair employment guidance emphasises transparent, merit-based treatment, and explaining restraints clearly at the offer stage reduces later disputes about what the employee understood.
Tripartite guidance and policy direction
The use of restrictive covenants in employment contracts has been the subject of tripartite discussion between MOM, unions and employers, in light of concerns that broad non-competes are being imposed on employees without a genuine need. Before relying on particular restraint wording, check MOM and TAFEP for the current tripartite guidance on restrictive covenants, which may set expectations on when restraints should be used and how they should be scoped.
Even before any guidance, the direction is clear: restraints should be reserved for employees who genuinely hold confidential information or client connections, should be explained to the employee at the offer stage and should be no wider than necessary. Employers that already follow these principles will find their covenants more enforceable as well as more defensible.
Enforcing a restraint: the process
When an employee leaves for a competitor, speed and evidence determine the outcome. A court considering an urgent application will want to see that the employer acted promptly once it learned of the breach.
- Gather the facts fast. Confirm the new role, the clients or staff approached and any evidence of information taken, including email forwarding, downloads and messages to clients.
- Preserve evidence. Secure the former employee's mailbox, device images and access logs, and record how the evidence was obtained, consistent with your monitoring policy and the PDPA.
- Assess enforceability. Test each covenant against the legitimate interest and reasonableness requirements, and identify which survive if others fail.
- Send a measured letter. Write to the former employee, and usually the new employer, setting out the obligations, the evidence of breach and the undertakings sought, with a short deadline.
- Seek undertakings or urgent relief. If undertakings are not given, consider an application for an interim injunction, including springboard relief where information has been misused. Our injunctions and urgent relief page explains the requirements.
- Pursue or settle the claim. Claim damages or an account of profits where loss has occurred, or negotiate a settlement with undertakings, delivery-up of information and a contribution to costs.

Confidential information: the backstop
Even where a non-compete fails, confidentiality obligations usually survive. They arise from the contract and from the equitable duty of confidence. In I-Admin (Singapore) Pte Ltd v Hong Ying Ting [2020] 1 SLR 1130, the Court of Appeal adopted a modified approach to breach of confidence claims, under which a presumption of breach arises once it is shown that information was confidential and was acquired or received without the owner's consent; the defendant must then show that its conscience was not affected. That approach strengthens the position of employers whose former employees download confidential material on leaving.
Confidentiality should therefore be the first line of protection, not an afterthought. Classify information, restrict access, use exit certifications and act quickly when downloads are detected. Client personal data taken by a departing employee also raises PDPA questions for both the employer and the new employer. Our confidential information and trade secrets team handles these claims.
Risks and common mistakes
Copying a restraint from another jurisdiction
Restraint clauses drafted for other legal systems often rely on concepts that do not translate, such as statutory payment for non-compete periods or courts' power to narrow an excessive restraint. Singapore courts generally do not rewrite an unreasonable covenant. A clause that might be trimmed to fit elsewhere can fail entirely here. Draft restrictive covenants in Singapore under Singapore law, with separate restraints that can stand alone if one is struck out.
Restraining everyone
Applying a 12-month non-compete to every employee, including administrative staff, signals that the purpose is to suppress competition rather than protect a real interest. It also damages credibility when the employer seeks to enforce the same clause against a senior employee who genuinely holds sensitive information. Tier restraints by role, and limit non-competes to the small group of people for whom confidentiality and non-solicitation are not enough.
Waiting too long to act
Interim injunctions are discretionary and depend on urgency. An employer that learns of a breach and waits weeks before writing, or months before applying to court, invites the argument that damages are an adequate remedy and that the restraint was not really needed. Have an escalation plan ready so that evidence is preserved and a decision on action is taken within days, not weeks.
Ignoring the new employer
Former employees often have limited assets, while the new employer may be the party benefiting from the breach. Depending on the facts, a new employer that induces breach of contract or receives confidential information may face its own liability. Writing to the new employer early, with evidence, often achieves more than proceedings against the individual. Conversely, when hiring from a competitor, check the candidate's restraints and instruct them not to bring any information.
Changing restraints without consideration
Introducing new or wider restraints in a handbook update or a group-wide contract refresh, without giving anything in return, leaves them open to challenge. Tie new restraints to a promotion, pay rise, retention bonus or equity grant, and document the link. For employees who refuse, consider whether the restraint is genuinely needed for their role.
Restrictive covenants in Singapore are won or lost on the day they are drafted: a narrow clause that fits the role is worth more than a broad clause that fits every role.
Cross-border restraints
Regional roles create regional restraint problems. A Singapore-based executive covering Bangladesh, the UAE and China may leave to join a competitor in Dubai, or a London-based manager may move to Singapore. Questions arise about governing law, which court has jurisdiction and whether a Singapore judgment or injunction can be enforced where the employee now works.
Restraint laws vary widely. Some jurisdictions are stricter than Singapore, some require payment during the restraint and some barely enforce non-competes at all. Draft the territory by reference to the markets the employee actually covers, choose a governing law and forum that fit where enforcement will be needed, and take local advice before relying on a restraint abroad. Our network allows us to coordinate enforcement steps across jurisdictions, including with the executive exits team where the departing employee is also a director.

Frequently asked questions
01Are non-compete clauses enforceable in Singapore?
Sometimes. A non-compete is presumed void as a restraint of trade and is enforceable only if the employer shows a legitimate proprietary interest, such as confidential information or client connections, and that the restraint is reasonable in scope, area and duration. Courts look at the clause as at the date it was signed. Non-competes are most likely to be upheld for senior employees with access to strategic information, and least likely for junior staff.
02How long can a restraint last?
There is no fixed maximum. The period must be no longer than reasonably necessary to protect the interest identified, which depends on how quickly client relationships and confidential information lose their value in the sector. Short periods are more defensible. Courts will consider the employee's role and seniority, any garden leave already served and whether the employer offered anything in return for the restraint.
03Will a court cut down an overly broad restraint?
Singapore courts generally do not rewrite an unreasonable covenant. They may sever offending words where the rest of the clause still makes sense without adding or changing anything, an approach often called the blue pencil test. That is why separate covenants for non-competition, non-solicitation and non-poaching, each with its own definitions, are far more resilient than a single wide clause.
04Can we add a restraint to an existing employee's contract?
Yes, but it needs the employee's agreement and generally fresh consideration, such as a promotion, pay rise, bonus or equity award. Imposing a restraint through a handbook update without consideration is vulnerable. Document the link between the new restraint and the benefit given, explain the reason for it, and ensure the restraint is justified by the employee's role and access to information.
05Is there tripartite guidance on restrictive covenants?
The use of restrictive covenants in employment contracts has been the subject of tripartite discussion involving MOM, unions and employers. Check MOM and TAFEP for the current tripartite guidance before relying on particular wording, because it may set expectations on when restraints should be used and how they should be scoped. Regardless of guidance, courts continue to apply the common law legitimate interest and reasonableness test.
06What can we do if a former employee joins a competitor?
Act quickly. Confirm the facts, preserve evidence of any information taken or clients approached, assess which covenants are enforceable and write to the former employee and usually the new employer seeking undertakings. If they are not given, consider an interim injunction, including springboard relief where information has been misused. Delay weakens the case for urgent relief, so have an escalation plan ready before departures happen.
07Does a restraint in a share sale work differently?
Yes. Restraints given by the seller of a business, or between shareholders, are assessed more generously than employment restraints because the parties negotiate on more equal terms and the buyer is paying for goodwill. A founder who sells and stays on may be bound by both a sale restraint and an employment restraint. Draft both deliberately, as the sale restraint can usually justify a wider scope and longer period.
