M&A Due Diligence Vietnam 2026: Legal, Land-use & Regulatory Checklist for Cross-border Buyers

Who this is for: in-house counsel, private equity deal teams and strategic acquirers with cross-border Vietnam targets. What it delivers: a practical, 2026-updated due diligence checklist covering legal, land-use, regulatory approvals, competition, tax and FX issues, with estimated timelines and red-flag scoring. What to do next: use the checklist to scope vendor due diligence, prepare share purchase agreement (SPA) conditions, and allocate escrow and indemnity budgets.

M&A due diligence Vietnam has entered a more demanding phase in 2026, as Vietnam’s investment, competition and land legislation continue to reshape how cross-border buyers assess transactional risk. Acquirers can no longer rely on generic playbooks: land-heavy targets, sector-specific licensing and foreign ownership limits now interact with approval requirements and filing triggers in ways that materially affect deal structure, price and closing certainty. This guide sets out a risk-based, buyer-side checklist that maps each verification step to the relevant Vietnamese law or regulator. Legal assertions are referenced to authoritative government sources so that deal teams can move quickly from scoping to signing. Treat this as a working framework, general information, not legal advice, to be tailored to each target.

Executive Summary: Core Due Diligence Checklist (Top 10 Buyer Must-Checks)

Before committing resources, confirm that your team addresses the ten checks that most frequently generate deal-breaking findings in Vietnam. This list is the fastest way to scope M&A due diligence Vietnam engagements and to prioritise data-room requests.

1. Corporate title and chain of ownership. Verify the enterprise registration, charter and unbroken share transfer history under the Law on Enterprises.
2. Foreign ownership limits. Confirm the target’s sector permits the intended foreign stake and identify inadvertent foreign shareholding.
3. Land-use rights and LURCs. Authenticate the Land-Use Right Certificate, area, classification and encumbrances against the competent land registry records.
4. Material contracts. Review supply, lease, EPC and offtake agreements for change-of-control and termination triggers.
5. Licences and permits. Check sector and operating licences are valid, transferable and not subject to revocation.
6. Regulatory filings. Confirm the Investment Registration Certificate and any change approvals under the Law on Investment framework.
7. Competition filing. Assess whether the transaction crosses economic-concentration notification thresholds requiring notification.
8. Tax exposures. Quantify open VAT, corporate income tax, withholding and transfer-pricing risks.
9. Labour and social insurance. Identify severance liabilities, union issues and social insurance arrears.
10. Environmental and litigation. Review environmental compliance and pending or threatened disputes.

These ten items answer the threshold question every acquirer asks: what due diligence is required for M&A in Vietnam? Each is expanded in the workflows below.

How to Scope Due Diligence for a Vietnam Acquisition (Deal Checklist & Risk Matrix)

Scoping determines cost, timeline and the depth of protection you can negotiate. Start by fixing the transaction structure, because the choice between a share purchase and an asset purchase drives which approvals, taxes and land-transfer restrictions apply.

Next, grade the target on three risk axes:

• Sector sensitivity. Regulated and conditional sectors such as banking, telecommunications, energy and real estate attract additional licensing and foreign-ownership scrutiny under conditions administered by the relevant line ministries and, for investment registration, the provincial investment authorities and the Ministry of Finance.
• Land intensity. Targets holding real estate demand a full LURC verification workflow; asset-light service businesses require less.
• Foreign investor profile. A foreign acquirer may trigger investment registration and, in some sectors, ownership caps that a domestic buyer would not face.

Use a simple risk matrix scoring each finding by likelihood and financial impact (low, medium, high). Findings scored high on both axes become conditions precedent or price adjustments; medium findings feed warranties and indemnities; low findings are disclosed and accepted.

A well-scoped M&A due diligence Vietnam exercise begins with a structured document request covering: constitutional documents; capitalisation tables and share registers; LURCs and lease agreements; all licences and permits; material contracts; recent years of tax filings and audit reports; labour contracts and social insurance records; environmental permits; and a litigation schedule. Requesting these upfront compresses the timeline and exposes gaps early.

Legal Due Diligence Vietnam: Corporate & Contracts Checklist

Legal due diligence Vietnam divides into two work streams, corporate structure and commercial contracts. Both must be traced to primary documents rather than management representations.

Corporate: Charters, Shareholder Structure and Chain of Title

Confirm that the target is validly incorporated and in good standing under the Law on Enterprises, with its enterprise registration certificate matching current operations. Reconstruct the full chain of title for the shares or charter capital being acquired: every transfer, capital contribution and charter amendment should be documented and consistent with board and shareholder resolutions.

Pay particular attention to:

• Inadvertent foreign shareholding. Historical transfers may have breached foreign ownership limits without the parties realising, creating a defect that can invalidate ownership or block the acquisition.
• Unusual powers and quorum rules. Charters sometimes grant minority veto rights, drag-along or pre-emption rights that affect deliverability of full ownership.
• Board minutes and corporate approvals. Verify that prior major transactions received the internal approvals the charter and Law on Enterprises require.

Where the target’s constitutional documents or share register are incomplete, treat the gap as high-risk. Ownership in a Vietnamese company is proved by the register or member list and transfer documentation; missing links cannot be assumed away and should convert into a condition precedent requiring rectification before closing. Statutory requirements for enterprises and investment activities are published on the National Legal Database (Vietnam Legal Document Portal).

Key Commercial Contracts and Change-of-Control Clauses

Material contracts frequently contain the hidden value, and hidden liabilities, of a Vietnamese target. Review supply agreements, customer offtake contracts, property leases, engineering-procurement-construction (EPC) agreements and financing documents for provisions that a change of ownership will trigger.

Focus your review on:

• Change-of-control clauses. These may allow counterparties to terminate, renegotiate or accelerate on completion of the acquisition, eroding the earnings the buyer is paying for.
• Assignment restrictions. In an asset deal, contracts may not transfer without counterparty consent, extending the timeline and creating leakage risk.
• Exclusivity and non-compete terms. These can constrain post-closing integration or expansion plans.
• Governing law and dispute resolution. Contracts referring disputes to foreign arbitration behave differently from those tied to Vietnamese courts.

Catalogue every contract requiring third-party consent and build the consent process into the closing timetable. Undisclosed change-of-control triggers are among the most common reasons deals lose value between signing and completion.

Land-Use Rights, Real Estate & Construction: The LURC Workflow in M&A Due Diligence Vietnam

Land is where Vietnamese deals most often unravel. Because private freehold does not exist, the target holds land-use rights evidenced by a Certificate of Land-Use Rights and Ownership of Assets Attached to Land (commonly the LURC). Understanding land-use rights in Vietnam M&A is essential, and it directly answers the question of how LURCs impact M&A due diligence in Vietnam.

What to Check in a LURC

The LURC is the single most important land document, but its face value must be independently verified. Check:

• Title authenticity. Confirm the LURC is genuine and matches the issuing authority’s records rather than a copy that has since been superseded.
• Registered area versus actual area. Discrepancies between the certificate, the cadastral map and the physical footprint are common and can shrink the acquired asset.
• Land classification and permitted use. Verify that the land category (industrial, commercial, residential, agricultural) matches the target’s actual and intended use; mismatches require reclassification.
• Term and remaining duration. Land is frequently held for a defined lease term; confirm how many years remain and the renewal mechanism, and whether the land is allocated or leased and whether rent is paid annually or as a lump sum.
• Encumbrances. Identify mortgages, guarantees or third-party rights registered against the land.

Land classification, LURC issuance and transfer procedures are governed by the Land Law, administered by the competent land-administration authorities under the responsible ministry (following the 2025 reorganisation, the Ministry of Agriculture and Environment) and provincial and district land-registration offices.

On-Site and Registry Verification

Never rely solely on documents supplied by the seller. Conduct independent verification through the land-registration office’s cadastral records and, where possible, a physical site inspection. Cross-check the LURC against the official cadastral map to confirm boundaries and area. Registry searches reveal mortgages and disputes not always disclosed in the data room.

Common red flags at this stage include: land use inconsistent with the registered classification; unauthorised construction lacking building permits; boundary encroachments; and land that has been contributed as capital or pledged without corresponding entries. Any of these should be scored high-risk and escalated.

Practical Fixes: Assignment vs Lease, Reclassification and Cure Steps

Where diligence surfaces land defects, buyers have several remediation routes. The right one depends on the deal structure and the target’s ownership rights.

• Assignment versus lease. Foreign investors face restrictions on directly holding certain categories of land-use rights; structuring the acquisition through the target entity (a share/capital purchase) rather than an asset transfer can preserve existing land rights that would otherwise face transfer limits.
• Reclassification. Where the use does not match the classification, apply to the competent land authority to reclassify or amend the permitted use before closing.
• Cure steps for construction. Regularise unpermitted construction or price the demolition and re-permitting cost into the deal.

Because land cures can take weeks or months, sequence them as conditions precedent and size escrow to cover the residual risk if a cure is only partially complete at closing.

Regulatory Approvals & Sector Licences: Mapping & Timelines

Identifying the regulatory approvals for a Vietnam M&A transaction early is decisive, because approvals gate the timetable. This section answers directly which regulatory approvals buyers should verify in Vietnam transactions.

Investment Approvals and Registration (M&A Approval)

Foreign investment into a Vietnamese target is registered and, in many cases, subject to approval under the Law on Investment framework. Where the target is an investment-project company, confirm it holds a valid Investment Registration Certificate consistent with its current activities, and determine whether the acquisition itself requires an M&A approval (registration to purchase shares or capital contribution) or an amendment to the certificate. Where a foreign investor acquires shares or capital in a company operating in a conditional sector, exceeds specified ownership thresholds, or where the target holds certain land, the change of investor typically requires prior registration with the competent investment-registration authority.

Procedures for issuing and amending investment certificates and the conditions applying to market-access sectors are published on the National Business Registration Portal and the National Foreign Investment Information Portal.

Industry and Sector Licences

Regulated and conditional sectors carry their own licensing regimes layered on top of investment approval:

• Energy and power. Generation, distribution and trading activities require electricity operation licences that must be confirmed valid and, where relevant, addressed on change of control.
• Telecommunications. Network and service licences are tightly regulated with foreign-ownership conditions.
• Banking and finance. Acquisitions of shares in credit institutions typically require State Bank of Vietnam approval before completion.
• Real estate. Real-estate business conditions and project approvals interact with land classification and project approvals.

For each licence, verify validity, remaining term, transferability on change of control and any conditions that the acquisition might breach. Sector conditions and competition-policy matters relating to trade and industry are maintained by the Ministry of Industry and Trade (MOIT).

Merger-Control Assessment and Notification Checklist

Economic concentrations are regulated under the Law on Competition and its implementing decree. Buyers must confirm whether the transaction is notifiable, assemble the current notification dossier and forms, and factor the review period into the closing schedule. Treat the merger-control assessment as a gating item and reference the applicable rules and forms published by the National Competition Commission under the Ministry of Industry and Trade.

Competition & Merger Control: Triggers, Filing Process and Timeline

Merger-control notification in Vietnam is mandatory where an economic concentration crosses the notification thresholds set under the Law on Competition and its implementing decrees. Because thresholds are defined by reference to combined assets, turnover, transaction value and combined market share, deal teams should assess notifiability at the term-sheet stage, not on the eve of signing.

The process typically runs as follows:

1. Assess thresholds. Determine whether the parties’ combined metrics trigger a filing obligation.
2. Prepare the notification. Complete the current notification forms and assemble supporting market and financial data.
3. Submit and clear the review. The National Competition Commission conducts a preliminary and, where necessary, an official appraisal before clearing, conditioning or prohibiting the transaction.

Non-notification, or closing before clearance where clearance is required, exposes the parties to administrative penalties. Reflect this in the SPA by making merger-control clearance an express condition precedent, and by prohibiting completion until clearance is obtained. Merger-control rules and forms are administered by the National Competition Commission under the Ministry of Industry and Trade.

Tax, Customs & FX Checks: Tax Due Diligence Vietnam

Tax due diligence Vietnam protects the buyer from inheriting undisclosed historical liabilities that survive a share/capital acquisition. Concentrate on the areas that generate the largest assessments.

• Corporate income tax (CIT). Review whether claimed incentives and exemptions were validly obtained and whether prior returns are defensible.
• Value-added tax (VAT). Check input-credit positions, refund claims and compliance with invoicing rules.
• Withholding and foreign-contractor tax. Confirm correct withholding on cross-border payments, royalties and services.
• Transfer pricing. Related-party transactions require contemporaneous documentation; gaps invite reassessment.
• Historical audits and open liabilities. Identify closed and open audit years and any assessed but unpaid amounts.

Note that gains on the transfer of shares or capital in a Vietnamese company are generally subject to Vietnamese tax; confirm the applicable treatment for the specific structure and seller. Where risks are material, obtain a tax opinion and, where the transaction structure permits, address tax obligations before completion. Guidance on CIT, VAT and withholding, and tax-administration procedures, is issued by the tax authority under the Ministry of Finance.

Cross-border acquirers must also confirm foreign-exchange feasibility. Payment of consideration, repatriation of dividends and future capital movements are subject to foreign-exchange controls, and the transaction usually requires the correct capital or investment account arrangements (for example, a direct or indirect investment capital account). Verify that the deal cash flows are permissible and that remittance can be executed. Foreign-exchange rules and capital-account requirements are set by the State Bank of Vietnam.

Employment, Social Insurance & Employee Transfers

Labour liabilities frequently surface after closing if not diligenced. Review labour contracts, internal labour regulations, collective bargaining agreements and severance obligations under the Labour Code. Confirm that social insurance, health insurance and unemployment insurance contributions are current, arrears become the buyer’s problem in a share deal and can be significant in labour-intensive targets.

In a transaction that changes the operating structure, examine whether employees continue automatically or require re-hiring, and quantify the severance or job-loss allowance exposure if roles are not continued. Vietnamese law imposes specific obligations, including a labour-usage plan, where a division, separation, merger or transfer of assets affects a large number of employees. Union relationships and any history of collective disputes should also be assessed, as these affect integration and reputational risk.

Environmental, IP, Litigation & Contingent Liabilities

Three further categories complete a thorough M&A due diligence Vietnam review.

• Environmental compliance. Confirm the target holds required environmental approvals, such as an approved environmental impact assessment or environmental licence, and check for contamination, waste-handling breaches or pending enforcement that could crystallise as clean-up costs.
• Intellectual property. Verify ownership and valid registration of trademarks, patents and key domain names, and confirm that IP created by employees or contractors has been properly assigned to the target.
• Litigation and disputes. Review pending, threatened and recently concluded proceedings, including enforcement risk. Selected court decisions and precedents are published by the Supreme People’s Court.

Score each contingent liability by probability and quantum. High-probability, high-value exposures should be provisioned through indemnities or price reductions; low-probability items can be managed through warranties and disclosure.

Practical Timeline & Sample Due Diligence Schedule

How long does legal due diligence take in Vietnam? The answer depends on target complexity and the approvals required, but the following ranges guide planning.

Structure the transaction across three phases, pre-signing diligence, a between-signing-and-closing period to satisfy conditions precedent and obtain approvals, and a post-closing phase for statutory filings. Land-heavy and regulated targets sit at the upper end of every range, so build contingency into the exclusivity period.

Deal Mechanics: SPA Gating, Conditions Precedent, Escrow & Indemnities

Diligence findings must be converted into contractual protection. Build the following into the SPA:

• Conditions precedent. Make completion conditional on merger-control clearance, investment and sector approvals, LURC rectification and any required third-party consents.
• Escrow for title and land risk. Where LURC or land-classification cures are incomplete at closing, hold back consideration in escrow sized to the estimated cure cost plus a buffer.
• Seller representations and warranties. Tailor reps to Vietnamese risk areas, valid title to shares/capital, no inadvertent foreign shareholding breach, tax compliance, social insurance currency, environmental compliance and land title accuracy.
• Specific indemnities. Where diligence identifies a known risk (an open tax audit, a boundary discrepancy, a pending dispute), take a specific indemnity rather than relying on general warranties.
• Indemnity caps and survival. Set caps and survival periods that reflect the assessed risk profile, with longer survival for tax and title claims.

Effective deal mechanics translate each red flag into either a condition precedent, an escrow amount, a specific indemnity or a disclosed and accepted risk, with nothing left unaddressed.

Post-Closing Integration & Regulatory Notifications

Post-merger integration in Vietnam begins with statutory housekeeping. Complete the required filings promptly to avoid administrative penalties and to secure the buyer’s ownership on the public record.

1. Update enterprise registration. Register the change of owner/members, legal representative and charter amendments with the business-registration authority.
2. Update the Investment Registration Certificate. Reflect the new investor and any changed activities with the investment-registration authority where applicable.
3. Transfer or update licences. Complete sector licence transfers and notify relevant regulators.
4. Register land changes. Where land rights or the holding entity change, update the LURC and cadastral records with the land-registration office where required.
5. Notify the tax authorities. File tax-registration updates with the competent tax authority.

Sequencing these steps immediately after completion prevents lapses that can invalidate licences or expose the buyer to penalties.
