If you are planning a Vietnam market entry translation workstream, I would treat it as a legal and operational risk issue from day one, not as an admin task at the end. Under Vietnam’s Investment Law 2025, Law No. 143/2025/QH15, effective 1 March 2026, and Decree 103/2026, your filing can be delayed at intake simply because one foreign-language document is not translated into Vietnamese and notarised in the form the authority expects. I see this mistake repeatedly when a foreign investor assumes a translation accepted in Singapore, Australia, or the UK will also be accepted in Vietnam. It will not.
This checklist is my practical guide to the core market entry translation obligations around the Investment Registration Certificate and the Enterprise Registration Certificate. It also covers the 2026 apostille shift, which is a significant policy change for any investor preparing to enter Vietnam on a fixed project timeline.
The Regulatory Requirement: Why Your Filing Must Be in Vietnamese
In Vietnam, state submissions must be in Vietnamese. If your source material is in English or another language, you need a certified translation and, for most IRC and ERC filings, notarisation in Vietnam. That is the baseline compliance rule under the current law and related implementing practice.
The cost of getting this wrong is not abstract. An incomplete investment or company file is rejected at intake, and a weak entry translation process can add weeks to your market entry. Most investors focus on structure, capital, and the commercial case for the Vietnamese market. I would focus first on whether every supporting paper is in the language and format the reviewing government officer will accept.
This is one area where Vietnam differs sharply from other ASEAN jurisdictions. In Singapore, ACRA works comfortably in English. In Indonesia, BKPM and OSS create a different sequencing problem around KBLI classification and downstream licences. In Vietnam, the language issue sits much earlier in the process, and it can block the entire entry strategy before your application is even assessed.
Certified vs Notarised Translation: What the Authority Actually Needs
A certified translation is a translator’s written confirmation that the text is accurate and complete. A notarised translation goes further: a notary public in Vietnam authenticates the translator’s signature and professional capacity under the Law on Notarization 2024. For IRC and ERC filings, I advise you to assume the authority will require notarised translations, not self-certified ones.
This distinction matters because many international service providers offer only certified output. That may be enough for internal review, tax planning, or industry research. It is not enough for the filing stage. If you are building a Vietnam market entry plan, your translation service should include authentication sequencing, local notarisation, and document control. Without that support, your business case may be ready while your legal file is not.
Apostille vs Consular Legalisation: The Significant 2026 Shift
Before a document can be notarised in Vietnam, you first need to prove it is genuine in the issuing country. Historically, that meant consular legalisation: notarisation at home, authentication by the foreign affairs authority, then legalisation by the Vietnamese embassy or consulate. For many investors, that added three to six weeks to the preparation timeline.
Vietnam acceded to the Hague Apostille Convention on 31 December 2025, and the Convention entered into force on 11 September 2026. From that date, investors from member jurisdictions can use an apostille instead of the older consular route. That is a significant improvement in the regulatory environment and a significant time saving if you are trying to enter Vietnam in Q4 2026 or Q1 2027.
One practical warning: if your home country is not in the Convention system, the older pathway still applies. I would not let anyone assume the apostille route is universal. In cross-border investment, the dangerous errors are usually the ones that look minor at first.
IRC Translation Checklist: The Core Investment File
For most new foreign investment projects, the IRC comes first. The investment registration file is where I see the highest concentration of translation and authentication errors, especially when a parent company is coordinating documents across several offices.
- Passport or national ID of an individual investor — notarised certified copy, with authentication if issued abroad.
- Certificate of incorporation or business registration of a corporate investor — apostille or consular legalisation, then notarised Vietnamese translation.
- Charter or articles of association — translated and notarised to confirm authority, ownership, and representative powers.
- Audited financial statements for the two most recent financial years — translated for proof of financial capacity and capital strength.
- Bank confirmation or equivalent proof of funds — translated and notarised; many authorities prefer recent issuance.
- Board resolution appointing the authorised representative — authenticated in the home country if signed abroad, then translated.
- Power of attorney — required if your advisory firm or legal representative files on your behalf.
- Project proposal or feasibility study — full Vietnamese version if your project sits in a conditional sector.
If you are a foreign investor in manufacturing, infrastructure, or another regulated industry, the authority may require additional proof around land use, technology, or sector-specific licences. That is why I treat the IRC file as a strategic document package, not just a translation exercise.
ERC Translation Checklist: The Company Formation File
The ERC creates the new company as a legal person in Vietnam. Under Decree 103/2026, some structures may move through the ERC stage earlier, but I would confirm the sequence with counsel before you rely on that approach.
- Corporate shareholder certificate of incorporation — authenticated and translated.
- Passport or ID of the authorised representative — notarised copy.
- Board resolution appointing the representative of the Vietnam entity — separate from the IRC authority paper and translated on its own.
- Registered office lease agreement — translation only if the lease is not already in Vietnamese.
- Draft charter of the Vietnam entity — usually prepared directly in Vietnamese by your local legal firm.
You should also keep the two certificates distinct in your internal planning. The registration certificate for investment approval serves a different purpose from the registration certificate for enterprise formation, even when the same investor team is collecting the papers. In practice, poor file separation is a common compliance problem.
Entry Model and Market Entry Strategy: Why Structure Changes the Translation Load
Your entry model determines the scope of the translation workstream. That is true in Vietnam, and I see the same principle in Indonesia, Thailand, and Malaysia, even though the agencies and thresholds differ. A weak market entry strategy usually creates unnecessary translation cost later because the wrong structure was chosen first.
A joint venture remains common in restricted or relationship-driven sectors. In a joint venture, I would expect both sides’ authority documents, the joint venture agreement, and the local partner file to be checked carefully against originals. A wholly foreign-owned entity is cleaner for many services and technology businesses, but it pushes more documents into the overseas authentication stream.
An entry model based on a representative office or branch can be a strong interim option for an international company testing demand before full incorporation. In that case, the branch or office file still needs translated establishment papers, representative credentials, and proof of parent authority. The entry model is therefore not only a tax or control decision; it is also a document-management decision.
Operational Documents After Incorporation
Your Vietnam market entry translation obligations do not end when the company is incorporated. A work permit application for overseas staff usually requires translated degrees, professional certificates, and employment records. A second work permit issue arises when titles or duties in the translated file do not match the labour submission.
If you operate in an industrial park, I would also prepare Vietnamese versions of sub-leases, operator agreements, and key supply chain contracts for inspection. In manufacturing, that matters more than many boards expect. An industrial park landlord, customs team, or another government body may ask for documents at short notice, and poor document control becomes an operational risk.
The same applies to tax and licensing records. Cross-border service agreements, brand licences, and other product or consumer-facing materials should sit in a clear compliance archive. If you are building a long term presence in the Vietnam market, this is where strong internal control really matters.
Timeline, Common Mistakes, and Validity Rules
For any investor, the sequence is straightforward in theory: authentication, translation, notarisation, submission. In practice, the timing goes wrong because teams split the work across the home country, a translation service, and a local advisory firm without one owner of the process.
- Using a provider that offers certified translation but no notarisation in Vietnam.
- Submitting older financial papers when the reviewing officer expects recent proof of capital and solvency.
- Failing to translate the board resolution and power of attorney as separate items.
- Assuming an overseas notarial act satisfies a domestic government notarisation expectation.
- Starting too early and letting time-sensitive papers expire before submission.
Most authorities accept many authenticated documents only within a three- to six-month window. That validity issue is a high-priority project-management point. If you start too early, you create a second round of cost. If you start too late, your market entry timeline slips. Neither outcome is strategic.
Why This Matters for Your Broader Vietnam Plan
Vietnam continues to offer real potential for manufacturing, trade, technology, and consumer growth. The economy remains a strong draw for boards assessing Southeast Asia, but I would not confuse macro growth with easy execution. The practical work of a foreign investor still turns on sequencing, compliance, and whether the documents presented to the authority match what the law and local practice actually expect.
If you are an international company assessing where to deploy resources across ASEAN, this is one of the reasons Vietnam deserves specific attention. The country can offer a fast-moving industrial and consumer ecosystem, but only if your legal, tax, and translation workflows move in the right order. That is where I would want strong local support, especially for an investor balancing regional strategy across Vietnam, Indonesia, Thailand, and Singapore.
If you need practical help on IRC, ERC, apostille planning, or broader market entry support, I recommend building the translation workstream into the full set-up process from the start.
