An investor had ten days to decide on acquiring a factory. Not enough time for full due diligence — but enough for a red-flag review, provided one knows exactly where to look and which findings mean stop rather than negotiate harder.
1. Current legal basis
A red-flag review is risk-selected screening: it examines only the points capable of changing the investment decision or the price, against the current framework including the Law on Investment 143/2025/QH15 (replacing Law 61/2020/QH14 from 1 March 2026), the Law on Enterprises 2020 and the relevant land, tax and labour rules. It differs from full due diligence in scope and depth: red-flag screening answers ‘is there a reason not to sign’, while due diligence answers ‘what does the whole legal picture look like’.
2. How this applies in practice
Classic red-flag groups are: investment and sector licences that do not match actual operations; leased land under dispute or nearing expiry with no renewal path; unsettled tax liabilities; prolonged underpayment of social insurance; and undisclosed ongoing disputes. Each can be checked quickly from original files if the seller cooperates with a data room.
A red flag does not automatically kill a deal: many are handled through price adjustments, escrow retentions, seller warranties or conditions precedent. The stop-signals are the unpriceable ones — a risk of land recovery or of losing a core licence — because no discount compensates for losing the entire operating foundation.
3. Steps to take
1. Agree the red-flag list for the target’s sector before opening the files, to avoid unfocused review.
2. Request a minimum data room: licences, land files, latest tax finalisations, a disputes list and material contracts.
3. Grade every finding three ways: stop the deal, reprice it, or handle it through contract terms.
4. Issue a short report by the agreed deadline, stating plainly what could not be verified for lack of documents.
4. Risks and post-checks
The biggest risk is using a red-flag review as cheap due diligence while expecting due-diligence depth: anything outside the screening scope will not appear in the report, and the investor signs with a false sense of full coverage. The report must state its scope limits on the first page.
