Post-employment non-compete clauses are not clearly enforceable in Vietnam. The Labour Code lets employers agree with employees on protecting business and technology secrets, including compensation if the employee breaches the agreement, but it does not expressly authorise a ban on working for a competitor after the job ends, and Vietnamese courts have often refused to enforce such bans because they restrict the constitutional right to work. Confidentiality obligations, trade secret protection and training-cost agreements are far more reliable tools.
This guide explains where the legal uncertainty comes from, how courts have tended to approach the issue, what an employer can do to protect itself without relying on a fragile clause, and what an employee should consider before joining a rival. It reflects the general position under the Labour Code adopted in 2019 and its guidance. The point is unsettled, so check the current rules and recent practice with a licensed lawyer before acting on a specific clause.
Where the uncertainty comes from
Vietnam's Constitution and the Labour Code protect the right to work and to choose one's occupation and workplace freely. Against that background, the Labour Code allows an employer, where an employee's work involves business secrets or technology secrets, to agree with the employee in writing on the content and duration of protecting those secrets, the benefits the employee receives, and compensation if the employee breaches the agreement. Guidance from the labour ministry describes such agreements and mentions their duration and the benefits involved.
What the law does not say in plain words is that an employer may prevent a former employee from working for a competitor, or from setting up a competing business, for a period after leaving. Supporters of non-competes read the secrets provision broadly: a short ban on working for a direct rival is one way of protecting secrets. Sceptics read it narrowly: the law allows protection of secrets themselves, not a general ban on employment, and any wider restriction conflicts with the right to work.
The result is a genuine grey zone. Multinational employers continue to include non-compete clauses, partly out of habit from home jurisdictions and partly for their deterrent effect. Employees sign them without much thought. The clause only gets tested when someone leaves for a rival and the former employer decides to sue, and at that point outcomes have been mixed.
How Vietnamese courts have tended to respond
Published court decisions in Vietnam are fewer and less systematically reported than in common-law countries, and there is no binding precedent specifically settling non-competes. From the cases that have been discussed in legal commentary, a pattern emerges. Courts have frequently treated broad non-competes as invalid or unenforceable where they simply forbid the employee from working in the industry, without a clear link to identified secrets, without a limited geographical or time scope, and without any payment to the employee during the restricted period.
Some decisions, particularly in commercial hubs, have been more receptive where the clause was tied to the protection of business secrets, was limited in time, and the employee had received a specific benefit in exchange. Courts have also distinguished between the employment relationship and separate civil agreements, though labelling a non-compete as a "civil contract" does not automatically take it outside labour law protections.
Even when a clause survives, the remedy matters. Vietnamese courts are generally more comfortable ordering payment of an agreed compensation amount than issuing an order forcing someone to stop working for a new employer. An employer hoping to keep a key salesperson away from a rival for a year may find that, at best, it recovers a sum of money long after the damage is done.
Protective tools ranked by reliability
Because the non-compete itself is fragile, experienced employers build several layers of protection. In rough order of how dependable they are in Vietnam:
| Tool | What it does | How reliable | Practical notes |
|---|---|---|---|
| Confidentiality obligations | Forbid disclosure and misuse of business and technology secrets during and after employment | High, if secrets are identified and protected in practice | Mark confidential material, restrict access, include in internal rules |
| Trade secret protection under IP law | Allows action against misuse of qualifying business secrets, including by former employees and their new employers | High, if the information meets the legal test for a business secret | You must show the information is secret, has commercial value and was protected by reasonable measures |
| Training-cost agreements | Require reimbursement of training costs if the employee leaves before an agreed period | High, within the rules on training contracts | Document the training and its cost; the agreement must be in writing |
| Non-solicitation of clients or staff | Restrict approaching the employer's customers or poaching colleagues | Uncertain, but narrower than a non-compete and easier to justify | Keep it targeted and limited in time |
| Post-employment non-compete | Bans working for competitors for a period after leaving | Low to uncertain | Improves with narrow scope, short duration, link to secrets and payment during the restriction |
The table is a guide to probabilities, not a guarantee. A court applies the law to the facts of each case, and practice varies between courts.
If you still want a non-compete: drafting choices that help
Tie it to real secrets. Identify the categories of business or technology information the employee actually handles, and explain why working for a competitor would put them at risk. A blanket ban on "the industry" is the version courts reject most often.
Keep it narrow. Name specific competitors or a clearly defined line of business, limit the geography to where the employer actually trades, and keep the duration short. A long restriction for a junior employee invites refusal.
Pay for it. An agreed monthly payment during the restricted period is the strongest signal that the restriction is a fair bargain rather than a one-sided penalty. It also gives the employer leverage: stop paying if the employee breaches.
Set a realistic compensation figure. An agreed amount payable on breach is easier for a court to award than unproven damages. An amount wildly out of proportion to salary can be reduced or refused.
Write it in Vietnamese. Employment contracts with workers in Vietnam must be in Vietnamese, though a bilingual version is common. The Vietnamese wording of a restrictive clause is what a court reads first.
Use a separate, signed agreement. Placing the restriction in a stand-alone agreement signed at the time the employee gains access to secrets, with the benefit stated, makes the bargain clear.
The employee's side: before joining a competitor
If you have signed a non-compete and receive an offer from a rival, the uncertainty cuts both ways. Many such clauses will not be enforced, but you cannot be sure yours is one of them, and a dispute can be stressful and expensive even if you win. Read the clause closely: what activities it covers, for how long, in which area, whether you were paid anything for it, and what compensation it specifies for breach.
Separate the non-compete from your confidentiality duties. Even if the non-compete is unenforceable, you remain bound not to disclose or misuse your former employer's business secrets, and taking client databases, pricing models or source code to a new employer can expose both you and the new employer to claims under intellectual property law. Leave company documents behind and return devices promptly.
Talk to your prospective employer. Serious companies hiring from competitors often ask candidates about restrictive covenants and may plan the start date or the scope of the role to reduce risk. Some agree to cover legal costs if the former employer sues. A hypothetical example: a sales director moving between two logistics firms in Da Nang agrees with the new employer not to approach clients he managed for six months, which is narrower than his non-compete but addresses the risk the old employer actually cares about.
What happens when an employer sues
An employer claiming breach of a non-compete usually seeks the agreed compensation amount, damages for losses it can prove, or both. Because the employment relationship has ended, the dispute is still treated as a labour-related dispute or a civil dispute depending on how the agreement was structured and the court's view. Jurisdiction and procedure follow from that characterisation, which is itself sometimes contested.
The employee's main defences are that the clause is invalid because it restricts the right to work without a lawful basis, that it is not linked to any identified secret, that it is unreasonable in scope or duration, that the employee received no benefit for it, or that the new job does not actually compete. The employee may also argue that the claimed compensation is disproportionate.
Litigation takes time, and by the time a judgment arrives the restricted period may have expired. That is why the practical value of a non-compete lies more in negotiation than in court: it gives the former employer a seat at the table when a key employee leaves, and often results in a negotiated arrangement covering clients, start dates or confidentiality assurances. Employers who understand that dynamic tend to draft for negotiation rather than for a courtroom victory.
When you need a Vietnamese lawyer
Employers should involve a licensed Vietnamese lawyer when designing restrictive covenants for senior staff, when a key employee announces they are joining a competitor, and before sending any demand letter. A lawyer can assess whether the information at risk qualifies as a business secret, whether the clause is worth asserting, and whether a trade secret or confidentiality claim would be stronger than a non-compete claim.
Employees should seek advice before resigning to join a rival if their contract includes a non-compete with a large compensation figure, if they are a senior manager or shareholder, or if they plan to start a competing business. Advice at that stage is far cheaper than defending a claim.
Questions worth putting to the lawyer: does the information I handle really qualify as a business secret, which court or forum would hear a claim, how have courts in this province treated similar clauses recently, is the compensation figure likely to be reduced, and what can I safely say to clients I used to manage? For employers, the parallel questions are whether a confidentiality or trade secret claim would be stronger, and what evidence of misuse already exists.
If you want a first opinion on whether a clause in your contract is likely to hold up, you can ask a lawyer on AI Co Van, then check the current rules and recent court practice with a licensed lawyer, because this is an area where the law and its interpretation continue to develop.
Frequently asked questions
Is a non-compete clause legal in Vietnam?
The law does not clearly prohibit or clearly permit a post-employment non-compete. The Labour Code allows agreements to protect business and technology secrets, with compensation for breach, but courts have often refused to enforce broad bans on working for competitors because they restrict the right to work.
Can my former employer stop me from starting a business?
A general ban on running a competing business is difficult to enforce in Vietnam. However, you remain bound by confidentiality obligations and trade secret law. Using your former employer's confidential information or clients in a new business can lead to claims, even if the non-compete itself is weak.
Does being paid during the restricted period make a non-compete valid?
Payment does not guarantee enforceability, but it strengthens the employer's position considerably. It shows the employee received a real benefit in exchange for the restriction, which helps answer the argument that the clause is a one-sided limitation on the right to work.
Can I be ordered to pay back training costs if I leave early?
Yes, if you signed a written training agreement under which you committed to work for a period after the training and you leave before it ends. The employer can claim the training costs set out in the agreement. Check how the costs were documented and calculated.
What counts as a business secret in Vietnam?
Generally, information that is not common knowledge, has commercial value because it is secret, and is protected by its owner through reasonable confidentiality measures. Customer lists, pricing structures, formulas and source code can qualify if they meet these tests in practice, not merely because a contract calls them confidential.
Should a foreign employer use its home-country non-compete template?
It is better not to copy it unchanged. A template designed for another legal system may be broader than a Vietnamese court will accept. Adapt it to Vietnamese law, tie it to identified secrets, narrow its scope, provide a Vietnamese version and consider payment during the restriction.
