Buying capital from an investor who is exiting carries one dangerous psychological feature: the seller wants to move fast, and that haste easily infects the buyer. But all of the enterprise’s past obligations – unfinalized taxes, unclosed guarantees, unsettled labor – do not exit with the investor; they stay with the enterprise the buyer is about to own. Due diligence is how the buyer sees what will stay there before paying.
This article provides the legal due diligence framework for acquiring capital from an exiting foreign investor: the standard review areas for the buyer; a structured checklist ready for use; the most common legal risks in this transaction type; and the factors that actually decide diligence timing.
Applicable Legal Framework
Due diligence is not a statutory procedure – Vietnamese law issues no diligence checklist for capital purchases. It is a professional process organized by the buyer, on the foundation of the legal regimes the target enterprise must comply with: the 2020 Enterprise Law (legal personality, capital, shareholders), the 2025 Investment Law (IRC, market access conditions, project status), tax and tax administration law (108/2025/QH15 – finalization, connected transactions, tax debts), the 2019 Labor Code and social insurance law, the 2024 Land Law (land-use rights, mortgaged assets), and sector law for sub-licenses.
The buyer’s only legal foothold in this process is contract: the confidentiality agreement and data room access, the letter of intent (LOI) recording diligence scope and negotiation exclusivity, and finally the representations – warranties – indemnities system in the transfer agreement, where every diligence finding is converted into risk allocation. Good due diligence does not end in a report; it ends in contract clauses and price adjustments matching what was found.
Detailed Answers to Practical Questions
What legal reviews are needed when acquiring capital from an exiting foreign investor?
Eight standard review areas. Area one – legal personality and capital: the enterprise registration certificate across changes, the current charter and its amendment history, the members/shareholder register, actual full payment of charter capital (bank documents), the real ownership structure through tiers, and side agreements the seller has signed. Area two – investment: the IRC and its adjustments, project implementation progress versus commitments, market access conditions of the business lines (especially where the buyer is also foreign and must pass Article 26 registration under the 2025 Investment Law), and the status of investment incentives and their ongoing conditions. Area three – tax: filing and finalization dossiers of recent periods, existing tax inspection minutes, connected transactions and transfer pricing dossiers, tax debts and disputed amounts, invoice status. Area four – labor: labor contracts, internal rules, collective agreements, the state of social/health/unemployment insurance payments, unpaid severance amounts, foreigners’ work permits and their validity. Area five – land and assets: land-use right certificates, land/factory lease contracts and remaining terms, assets under mortgage/pledge (searching the secured transactions registry), duty-free imported machinery not yet customs-liquidated. Area six – sub-licenses and sector compliance: all operating licenses for conditional business lines, their terms and maintenance conditions. Area seven – material contracts: major customer/supplier contracts, loan and guarantee contracts (including guarantees for the parent/related companies), change-of-control clauses in those contracts. Area eight – disputes and compliance: court/arbitration cases, sanctioning decisions, ongoing inspections, and uncompleted commitments with state agencies. Add one layer specific to the ‘exiting seller’ factor: verify the seller is not under transaction restrictions in its home country (insolvency, asset freeze) and that the signatory has proper authority – because a transaction with a seller lacking capacity can be challenged by third parties later.
Is there a standard due diligence checklist for the buyer?
No state-issued list exists, but there is a professional standard framework law firms use for capital acquisitions in Vietnam, organized into five document layers. Layer A – enterprise and investment documents (requested first, for quick screening): the complete enterprise registration dossier, charter, shareholder/members register, IRC and project dossier, the list of managers and legal representatives across periods. Layer B – finance and tax: financial statements of the last 3 years (audited if any), corresponding tax filings and finalizations, connected transaction dossiers, detailed receivables/payables, loan balances and repayment schedules, investment capital account statements. Layer C – assets and contracts: land papers and major asset documents, the fixed asset list with equipment import dossiers, lease contracts, material commercial contracts, insurance contracts, IP registrations, and all sub-licenses. Layer D – labor and compliance: the personnel list and applied labor contract templates, social insurance dossiers, registered labor rules, foreigners’ work permits, sanctioning decisions and inspection minutes of the last 3-5 years. Layer E – disputes and off-balance-sheet commitments: the list of lawsuits/disputes, issued guarantee letters and commitments, unrecorded obligations toward partners and state agencies. How to use this framework in practice: send the request list in the five layers the moment the LOI is signed, open a data room with an access log, and maintain an issues log classified red – amber – green; every red item must have a destination in the contract: a price reduction, a condition precedent to close before closing, a specific representation – indemnity, or a retention amount. A red item with no contract destination is a risk the buyer knowingly volunteers to bear.
What are the most common legal risks when acquiring capital?
Five risks account for most post-M&A disputes at FDI enterprises in Vietnam. Risk one – hidden tax debts and connected transactions: the enterprise bought/sold with its parent for years on thin transfer pricing dossiers; when the tax authority inspects finalization (especially around ownership change), arrears belong to the enterprise – i.e. to the buyer after closing. This is why a past-tax indemnity clause and a retention are standard in this transaction type. Risk two – unclean land and factories: annually-rented land used beyond its purpose, unpermitted construction on leased land, or assets mortgaged for the parent’s loans that the buyer never searched in the secured transactions registry. Risk three – labor and insurance: multi-year social insurance arrears, unpaid severance, expired work permits of specialists still working – these amounts are collected by authorities with penalties and belong to the enterprise. Risk four – sub-licenses and sector conditions effectively lost: the license is in date on paper but its maintenance conditions (capital, certified personnel, facilities) are no longer met once the seller’s team leaves. Risk five – the seller’s off-balance-sheet commitments in the enterprise’s name: guarantees for the parent’s loans, support commitment letters, long-term related-party contracts at unfavorable prices still in force. All five risks share one feature: they are not in summary financial reports but in source dossiers – and only due diligence reading source dossiers sees them.
How long does due diligence take?
There is no standard period, because the diligence clock runs on three variables outside the buyer’s will. Variable one – data room readiness: a seller with a team preparing orderly dossiers closes the first diligence round within weeks; a seller ‘searching while submitting’ adds days to every Q&A round, and finding quality drops because documents arrive piecemeal. Variable two – the target’s scale and complexity: a small trading company with few assets is wholly different from a factory with land, hundreds of employees, duty-free machinery, and sector licenses – the review scope and the number of authorities to verify against (business registration, secured transactions registry, customs, social insurance) grow by orders. Variable three – the number of finding rounds: diligence rarely ends in round one; every red finding opens another supplementary document round and another risk-allocation negotiation round. Honest scheduling: agree in the LOI a diligence window with seller document-delivery milestones and an extension mechanism, while accepting internally that diligence time buys certainty – shortening it by cutting review areas is buying blind risk with real money. In practice, for mid-size FDI capital deals in Vietnam, the legal-tax diligence window is usually budgeted at several weeks for a simple enterprise and considerably longer for a complex manufacturer; the final committed figure should be fixed only after the buyer sees the actual data room index.
Action Checklist
- Send the 5-layer request list (enterprise-investment / finance-tax / assets-contracts / labor-compliance / disputes-off-balance-sheet) the moment the LOI is signed
- Verify independently instead of only reading seller-submitted documents: secured transactions registry, enterprise registration status, land information where accessible
- Every red finding must have a contract destination: price reduction, condition precedent, past-tax indemnity, or retention
- Review the ‘exiting seller’ layer separately: signing authority, the seller’s legal status in its home country, whether the deal can be challenged
- Scrutinize the 5 high-frequency risks: tax/connected transactions, mortgaged land, social insurance arrears, lapsed license conditions, off-balance-sheet guarantees
- Schedule diligence by document-delivery milestones in the LOI; never cut review areas to buy speed
- Keep the red-amber-green issues log throughout and close its status at closing as a transaction dossier annex
Frequently Asked Questions
What if the seller refuses to provide certain documents in due diligence?
The buyer has three tools, used by the document’s importance. For minor documents: record the refusal in the issues log and compensate with a seller representation – warranty in the contract plus indemnity if the representation proves false. For material documents (tax, land, guarantees): make provision a condition precedent to closing, or price the deal on the worst-case assumption and hold a corresponding retention. For documents whose refusal is itself a red signal (e.g. tax finalization dossiers of periods with large connected transactions): the buyer should consider stopping the deal – a seller who will not show tax dossiers is transferring an unmeasurable risk to the buyer, and no price discount quantifies an unmeasurable risk.
Due diligence finds the enterprise owes years of social insurance – how is that handled?
The social insurance debt belongs to the enterprise, so after closing it remains an obligation of the enterprise the buyer owns. Three customary handlings: require the seller to pay in full and close confirmation with the social insurance authority BEFORE closing (made a condition precedent); or deduct the debt and expected penalties directly from the transfer price with the seller’s representation on the completeness of the debt figures; or hold a retention equal to the debt plus a safety margin, released when the enterprise presents confirmation of settlement with the insurance authority. Every option must rest on the actual debt confirmation from the social insurance authority, not on the enterprise’s self-declared books.
If the buyer is a foreign investor, are there additional diligence areas?
Two added areas. One serves the buyer’s own transaction: diligence the target’s business lines and ownership structure to determine whether the deal falls under Article 26 registration of the 2025 Investment Law (conditional lines, the over-50% threshold, sensitive-area land) and to prepare that registration dossier. The other is reverse diligence on post-acquisition maintenance conditions: whether the enterprise’s investment incentives, sector licenses, and contracts carry clauses tied to the owner’s nationality/ownership ratio (e.g. change-of-control clauses in industrial park land leases or loan contracts) – these clauses decide whether the buyer keeps the valued worth intact after takeover.
