Summary: Legal due diligence before an M&A transaction in Vietnam should go beyond confirming corporate existence — it should identify ownership gaps, licensing issues, contract exposure, employment liabilities and pending disputes before signing. This article outlines the practical scope of legal due diligence that investors, CFOs and buyers should expect when acquiring or investing in a Vietnamese company, including in the East Ho Chi Minh City area.

“Buyers who skip legal due diligence to move faster almost always pay for it later — the liabilities that surface after closing were sitting in the corporate file the whole time, waiting to be read before signature rather than after.” — Attorney Vu Manh Quynh, Founder & Managing Partner, ECOVIS Vietnam Law
Why This Matters for Investors and Buyers
Many M&A transactions in Vietnam proceed on the basis of financial due diligence alone, with legal review treated as a formality. In practice, legal due diligence often uncovers issues that materially affect valuation or deal structure — unregistered capital contributions, expired licenses, undisclosed related-party transactions, or contracts with change-of-control clauses that could be triggered by the transaction itself. Identifying these issues before signing generally allows the buyer to negotiate price adjustments, indemnities or conditions precedent rather than inheriting the risk after closing.
For buyers acquiring companies based in or operating through East Ho Chi Minh City — including manufacturing, trading and services entities in Thu Duc and surrounding industrial areas — legal due diligence should also account for local land use rights, factory lease terms and any incentive certificates tied to specific investment locations, as these may not transfer automatically with a change of ownership.
Key Legal and Compliance Issues
- Corporate records and ownership verification. Due diligence should confirm the target’s actual shareholding or capital contribution structure matches its Enterprise Registration Certificate and internal records, and that all capital contributions were made within the legally required timeframe. Discrepancies between registered and beneficial ownership are a frequent finding.
- Licensing and business line review. The target’s Investment Registration Certificate, sub-licenses and any conditional business line approvals should be checked for validity, scope and whether they will survive the proposed transaction structure (share deal versus asset deal).
- Material contracts and change-of-control clauses. Key customer, supplier, financing and lease agreements should be reviewed for termination rights, exclusivity, and change-of-control provisions that could be triggered by the acquisition, potentially disrupting revenue or operations post-closing.
- Employment and management issues. Labor contracts, work permits for foreign employees, social insurance compliance and any pending labor disputes should be reviewed, as unresolved employment liabilities often transfer with the entity in a share deal.
- Litigation, regulatory risk and tax exposure. Pending or threatened litigation, administrative penalties, and unresolved tax assessments should be identified and, where possible, quantified, as these may affect the negotiated purchase price or require specific indemnities.
- Related-party transactions and intercompany arrangements. Transactions between the target and its affiliates, founders or management should be reviewed for arm’s-length terms and proper corporate approval, as improperly authorized transactions may expose the buyer to later challenge.
- Transaction documents and conditions precedent. Findings from legal due diligence should be reflected in the sale and purchase agreement through representations, warranties, indemnities and conditions precedent — rather than left as informal understandings between the parties.
Practical Risks for Management
- CEO/founders (seller side): may face delayed closing or price adjustment if disclosure schedules are incomplete or inconsistent with due diligence findings.
- CFO (buyer side): may inherit unrecorded liabilities if tax and accounting due diligence is not properly coordinated with legal review.
- Board: may approve a transaction without full visibility into licensing or contract risks if due diligence reports are not reviewed before signing.
- Shareholders: may face post-closing disputes if representations and warranties are not adequately negotiated based on due diligence findings.
What Companies Should Review
- Confirm actual capital contribution and ownership records against statutory filings.
- Verify validity and scope of all licenses, sub-licenses and conditional approvals.
- Review material contracts for change-of-control and termination clauses.
- Assess employment records, work permits and pending labor disputes.
- Identify pending litigation, administrative penalties and tax assessments.
- Review related-party transactions for proper authorization and arm’s-length terms.
- Confirm whether land use rights, leases or incentive certificates will transfer with the transaction structure.
- Ensure due diligence findings are reflected in representations, warranties and conditions precedent.

FAQ
How long does legal due diligence typically take for a mid-size Vietnamese company?
Timelines vary depending on the target’s corporate history and document availability, but investors should generally allow sufficient time for a thorough review rather than compressing it to meet an arbitrary signing date.
Does a share deal or asset deal change the scope of due diligence?
Yes — in a share deal, liabilities generally transfer with the entity, so due diligence tends to be broader, while an asset deal may allow more selective assumption of specific assets and liabilities.
What happens if due diligence uncovers unresolved tax liabilities?
Depending on the specific facts, these may be addressed through price adjustment, escrow arrangements, or specific indemnities in the sale and purchase agreement.
Are foreign ownership limits relevant in due diligence?
Yes — due diligence should confirm the target’s business lines are not subject to foreign ownership restrictions that would affect the buyer’s intended shareholding.
Can undisclosed related-party transactions affect the deal?
They may, particularly if such transactions were not properly authorized or were conducted on non-arm’s-length terms, potentially requiring further investigation or adjustment.
Should due diligence continue after signing but before closing?
In many transactions, confirmatory due diligence continues through to closing to verify no material adverse changes have occurred.
