Legal Due Diligence (LDD) in Vietnam M&A Transactions: A Practical Guide for Japanese Companies
For Japanese companies pursuing M&A in Ho Chi Minh City and Hanoi, NEXORA Law Firm supports risk analysis and deal optimization through Legal Due Diligence (LDD).
01 - Objectives of Legal Due Diligence (LDD) in Vietnam M&A Transactions
1. Accurately Understanding the Target Company — The Foundation for Investment Decisions
Legal Due Diligence ("LDD") is the first and most critical step in any M&A transaction.
Its purpose is to enable the investor to gain a multi-dimensional understanding of the target company's business, financial condition, legal structure, and potential risks, so as to make an accurate investment decision and arrive at a fair valuation of the company.
Ho Chi Minh City and Hanoi are home to a concentration of diverse businesses across manufacturing, trading, and services, and M&A activity in both cities is brisk. NEXORA LAWFIRM has a strong track record supporting M&A transactions for Japanese companies, and consistently stands alongside investors through the LDD process to avoid legal risk and maximize the value realized after acquisition.
2. Structuring the Optimal Deal Scheme
Depending on the form of investment (share acquisition, asset transfer, merger, etc.), the findings of the LDD are used to optimize the transaction structure. The Legal Due Diligence Report (LDDR) provides the underlying basis on which legal advisors propose the method, timing, and conditions of transfer, and is indispensable to carrying the deal forward efficiently and with certainty.
3. Confirming Liabilities, Assets, and Rights
LDD involves a detailed review of the target company's financial liabilities, loan agreements, labor contracts, fixed assets, land use rights, intellectual property, and similar matters. This process not only allows the buyer to identify risk but also provides leverage in negotiating the seller's representations, warranties, and indemnification provisions.
4. Laying the Groundwork for the Share Purchase Agreement (SPA)
Based on the LDD findings, counsel drafts and revises the key provisions of the M&A agreement (Share Purchase Agreement).
For example, clearly defining:
the scope of the seller's representations and warranties,
the mechanism for addressing risks if they materialize,
the payment terms and conditions for transfer of ownership,
strengthens the overall security of the agreement and better protects the investor's interests.
5. Confirming the Approvals and Licenses Required for the Transaction
In Vietnam, certain M&A transactions require prior approval from state authorities — for example, the National Competition Commission (NCC), the Department of Planning and Investment (DPI), or an industrial park management board.
Through LDD, specialists identify and organize these legal approval and notification processes to help ensure the transaction proceeds lawfully and smoothly.

02 - Categories of Legal Due Diligence (LDD) in M&A Transactions
LDD can broadly be classified along two axes, depending on the position of the parties to the transaction and the purpose of the investment.
1. Classification by the Party Conducting the Review
(1) Vendor Due Diligence
This type is led by the seller (the company's owner) and is commonly adopted in connection with a share sale process or a transfer of the business to a third party.
This due diligence plays an important role as a preparatory step to facilitate smoother negotiations with the buyer, by:
ensuring legal and financial transparency, and
identifying and remedying potential internal risks in advance.
(2) Buyer's Due Diligence
This is the most common type, in which the buyer engages independent legal specialists to evaluate and analyze the target company as a whole.
The findings of buyer-side LDD are used as the basis for:
determining the acquisition price,
negotiating representations and warranties, and
the ultimate investment decision.
2. Classification by Scope of Investigation
(1) Full-Blown LDD
This is the broadest and most detailed form of LDD, examining every legal aspect of the target company.
Examples of items reviewed:
the company's legal status, capital structure, and shareholder composition
the status of business, investment, and environmental licenses
contractual relationships (commercial contracts, financing agreements, labor contracts, tax, fire safety, intellectual property, and litigation)
This type is suited to large-scale transactions and deals in which the buyer will take over control after acquisition, and it gives investors a high degree of assurance.
(2) Red-Flagged LDD
Unlike full-blown LDD, this approach focuses only on the critical risks that could directly affect whether the deal proceeds — for example, risk of contractual breach, missing licenses, or material litigation. The objective is to identify potential "deal-breakers" early, speed up decision-making at the initial stage, and reduce cost and time.
NEXORA's Recommendation
In the Ho Chi Minh City M&A market, hybrid due diligence combining "Vendor LDD" and "Buyer LDD" has become increasingly common in recent years. This approach allows both seller and buyer to ensure symmetry of information and negotiate more smoothly.
NEXORA LAWFIRM draws on its extensive practical experience in Vietnam to offer the LDD service best suited to the nature of each transaction — flexibly ranging from an initial-stage screening to a comprehensive, detailed due diligence for multinational clients.
03 - The Legal Due Diligence (LDD) Process in Vietnam M&A Transactions
Stage 1: Preliminary Research
The first step of LDD is to gather basic information about the target company. The goal at this stage is to define the scope of the investigation and identify the risk areas that require closer scrutiny.
Key sources of information include:
National databases: the National Business Registration Portal (NBRP), the National Office of Intellectual Property (NOIP), the National Registration Agency for Secured Transactions (NRAST), the State Securities Commission (SSC), and the stock exchanges (HOSE/HNX), among others.
Public disclosures: financial statements, annual reports, and audit reports.
Information provided by the company: sale proposals, self-disclosed materials, and internal documents provided during negotiations.
Thorough investigation at this stage makes it possible to identify capital structure, shareholder relationships, licensing status, and legal issues at an early point, and helps prevent problems in later phases.
Stage 2: Data Collection & Review
Once the scope of the investigation has been defined, the legal team prepares an information request list (questionnaire) and submits it to the target company. Information is typically provided through a virtual data room (VDR), ensuring confidentiality and access control.
At this stage, the following work is carried out:
preparing supplementary questionnaires to clarify unclear points;
cross-checking, verifying, and confirming the authenticity of submitted materials;
organizing and analyzing preliminary risk findings.
This clarifies the key issues that should be reflected in the final report.
Stage 3: Preparing the Legal Due Diligence Report (LDDR)
The LDDR is the final output summarizing the results of the investigation, and it is generally prepared in two stages.
Preliminary LDD Report:
Reports material risks identified during the initial investigation promptly, so the buyer can adjust the deal structure accordingly.
Final LDD Report:
Divided into two types:
(i) Full-Blown Report: a detailed report covering all legal matters concerning the company.
(ii) Red-Flagged Report: a report focused on the material risks affecting price or execution of the transaction.
A distinguishing feature of the LDDR is that it does not merely list risks, but includes specific remedial measures and recommendations for improvement.
This makes it possible to design the representations and warranties and the risk-allocation mechanisms in the M&A agreement.

04 - Key Areas of Legal Due Diligence to Consider in Vietnam M&A Transactions
Legal Due Diligence (LDD) is the single most important process for accurately assessing the target company's value, legality, and transferability in an M&A transaction.
While the areas of focus vary by industry and deal structure, LDD is generally carried out with attention to the following four main areas:
matters concerning the company
matters concerning licensing and business operations
matters concerning finances and liabilities
matters concerning contractual relationships
1. Matters Concerning the Company
As the first stage of LDD, it is important to clarify the target company's legal status, ownership structure, and any restrictions on share transfer.
Confirming transfer restrictions: examining pre-emptive rights, transfer restrictions, and veto rights set out in shareholder agreements or the charter.
Confirming shares and capital contribution status: reviewing the shareholder register, history of capital contributions, history of share transfers, and whether any share-pledge agreements exist.
Confirming investment restrictions: reviewing the cap on foreign ownership, whether the sector is a conditional business line, and compliance with foreign investment registration requirements.
Particular care is required in Ho Chi Minh City and Hanoi, where caps on foreign ownership are sometimes imposed in sectors such as manufacturing and logistics.
2. Matters Concerning Licensing and Business Operations
This area bears directly on the legality of the company's business operations.
Counsel confirms whether the industry-specific "sub-licenses" have been obtained and maintained, and whether the company complies with related regulations.
Confirming licenses: verifying the acquisition and renewal status of the business license, the Investment Registration Certificate, environmental permits, occupational safety, fire safety, and other permits.
Confirming regulatory compliance: checking periodic reporting obligations, notification obligations upon changes to registered information, and reporting obligations to the relevant authorities.
Failure to comply with these obligations can result in administrative penalties, suspension of operations, or revocation of licenses — any of which could materially affect the value of the M&A transaction.
3. Matters Concerning Finances and Liabilities
This is one of the most important areas within LDD, requiring simultaneous review from both a legal and a financial perspective.
Confirming liabilities: investigating the status of loan repayment, interest terms, contingent liabilities, any foreign-currency-denominated borrowing, and whether foreign borrowing has received the required approval.
Confirming security obligations: confirming the registration of security interests over real estate, movable assets, and shares (NRAST registration), and verifying the legality of any release of security.
Foreign-invested companies in particular need foreign-exchange registration for loans from overseas parent companies or foreign banks, and any deficiency in this procedure can later give rise to legal risk or a breach of foreign exchange regulations.
4. Matters Concerning Contractual Relationships
Review of contractual relationships is one of the most important elements of the LDD report.
Because contract terms directly reflect the company's rights, obligations, and allocation of risk, this review calls for particular care.
Confirming legal aspects: examining the validity of contracts, termination clauses, change-of-control provisions, third-party consent requirements, and rights of disposal over assets.
Confirming commercial aspects: reviewing exclusivity, non-compete, minimum purchase obligations, and obligations triggered by restructuring — provisions that affect business operations.
For foreign investors such as Japanese companies, a thorough understanding of the terms of long-term commercial contracts is directly linked to preventing post-acquisition disputes and avoiding losses.
