Top Mistakes to Avoid During Legal Due Diligence in Vietnam: A Comprehensive Guide 



Conducting thorough legal due diligence is crucial for any investor considering mergers and acquisitions (M&A) or other business ventures in Vietnam. However, there are common mistakes that can undermine the due diligence process, leading to costly risks and missed opportunities. This comprehensive guide outlines the top mistakes to avoid during legal due diligence in Vietnam and offers strategies to ensure a smooth, risk-free transaction. 

1. Overlooking Land-Use Rights in Real Estate Transactions

One of the most common mistakes in Vietnam’s real estate sector is failing to verify land-use rights properly. Land in Vietnam is state-owned, and companies or individuals hold land-use rights certificates (LURCs). Misunderstanding these rights or neglecting to confirm their validity can lead to disputes, delays, or legal challenges post-transaction. 

Mistake: Assuming Ownership Instead of Land-Use Rights 

Many investors mistakenly believe they are purchasing land outright, when in fact they are acquiring the right to use the land for a specific purpose under Vietnamese law. 

How to Avoid: 

Verify the validity and terms of the LURCs through a detailed review of legal documents. Ensure that the land-use rights align with the intended development or usage plans and comply with local zoning laws. 

Example: A foreign investor in the real estate sector found that the property’s LURC only permitted agricultural use, leading to delays in obtaining the required approvals for commercial development. 

2. Failing to Identify Beneficial Ownership

Another critical mistake is failing to uncover the actual beneficial owners of a company, especially in family-owned or privately-held Vietnamese enterprises. The ownership structure may be complex, with shares held through multiple layers of entities or by family members, making it difficult to determine who truly controls the company. 

Mistake: Relying on Legal Ownership Alone 

Relying solely on legal ownership can obscure the real decision-makers, leading to disputes post-acquisition or unexpected management changes. 

How to Avoid: 

Conduct thorough due diligence on the ownership structure, identifying both legal and beneficial owners. Engage local experts to investigate any hidden or undisclosed ownership interests. 

Example: An investor seeking to acquire a family-owned Vietnamese company failed to identify the beneficial owner, leading to disputes when a key family member exercised control over major business decisions after the acquisition. 

3. Ignoring Regulatory Compliance in Sector-Specific Deals

Vietnam has numerous sector-specific regulations, particularly in industries such as telecommunications, energy, banking, and logistics. Ignoring these industry-specific requirements can lead to regulatory violations, fines, or the invalidation of a deal. 

Mistake: Assuming General Compliance Is Sufficient 

Investors may assume that compliance with general business laws is enough, without understanding that certain industries have stringent foreign ownership restrictions, licensing requirements, or environmental compliance mandates. 

How to Avoid: 

Work with legal experts familiar with the specific industry regulations that apply to the target company. Ensure that the company holds all necessary licenses, permits, and approvals from regulatory authorities before proceeding with the deal. 

Example: A foreign investor in the renewable energy sector failed to secure approval from the Ministry of Industry and Trade, leading to delays in project implementation. 

4. Overlooking Intellectual Property (IP) Issues

Intellectual property is a significant asset, especially for companies in technology, pharmaceuticals, and manufacturing. Failing to review IP ownership, registration, or protection during due diligence can expose investors to infringement claims, disputes, or even loss of valuable IP assets. 

Mistake: Assuming IP is Registered and Protected 

Investors may overlook the need to verify whether patents, trademarks, and copyrights are properly registered and enforceable in Vietnam. 

How to Avoid: 

Conduct a comprehensive review of all IP assets, ensuring that they are registered with Vietnam’s National Office of Intellectual Property (NOIP) and comply with local IP laws. Investigate any pending disputes or claims related to IP infringement. 

Example: An international technology company discovered post-acquisition that the target company’s key software patent was not registered in Vietnam, leaving the company vulnerable to competitors. 

5. Failing to Review Financial and Tax Liabilities

Vietnam’s tax and financial landscape is complex, with varying corporate income taxes (CIT), VAT, and transfer pricing regulations. Investors who fail to thoroughly review a company’s financial and tax records may inherit substantial liabilities that can affect the profitability of the transaction. 

Mistake: Relying on Unaudited Financial Statements 

Relying on unaudited or incomplete financial statements can obscure hidden liabilities, unpaid taxes, or inconsistencies in reporting. 

How to Avoid: 

Engage financial and tax experts to review all financial documents, including tax filings, transfer pricing policies, and any pending tax audits. Ensure that the company is compliant with Vietnam’s tax regulations and that all potential liabilities are disclosed before the transaction. 

Example: A foreign investor purchasing a Vietnamese manufacturing company uncovered significant unpaid taxes during due diligence, leading to a renegotiation of the deal terms. 

6. Neglecting Labor Law Compliance and Employment Contracts

Vietnam’s Labor Code imposes strict regulations on employment contracts, wages, working conditions, and social insurance contributions. Failing to review labor law compliance can expose investors to significant risks, including fines or legal disputes with employees. 

Mistake: Assuming All Employment Contracts Are Compliant 

Investors may assume that employment contracts are compliant without reviewing whether the company has met all labor law requirements, including social insurance contributions and worker rights. 

How to Avoid: 

Review all employment contracts and ensure compliance with the Vietnamese Labor Code. Verify that the company is up to date with social insurance payments and that there are no ongoing labor disputes or claims. 

Example: An investor in the hospitality sector discovered that the target company had failed to pay social insurance for part-time workers, leading to potential financial liabilities. 

Conclusion: Ensuring a Smooth Due Diligence Process 

Conducting legal due diligence in Vietnam is essential for mitigating risks and ensuring a successful investment. By avoiding common mistakes such as overlooking land-use rights, failing to verify ownership structures, and neglecting tax liabilities, investors can protect their interests and secure a legally sound transaction.
