In a capital acquisition, the buyers most dangerous moment comes right after the money leaves its account: the shares have changed hands, but risks warranted not to exist can surface at any time. Escrow exists to bridge that trust gap: part of the purchase price is retained with a neutral third party, usually a blocked account at a bank, and released to the seller only when post-closing conditions are confirmed. For a foreign buyer in Vietnam, the escrow must also be designed so it does not collide with investment capital account rules.
The Legal Framework You Need
Vietnamese law has no standalone escrow statute for M&A; the mechanism is built from contract combined with a bank blocked account service. The common structure is a tripartite agreement among buyer, seller and an authorised bank, under which the bank holds the blocked funds and releases them only upon receiving the document set or joint confirmation exactly as the agreement prescribes. The retention serves two purposes: securing the seller indemnity obligations for breached representations and warranties, and securing specific known obligations such as a potential tax assessment or unfinished land paperwork outstanding at closing.
The most important legal intersection for a foreign investor is the money route: both the price paid to the seller and the amount placed in escrow relate to a capital transaction with a non-resident party, so the flow must be compatible with Circular 38/2026/TT-NHNN on investment capital accounts. The parties should agree with the escrow bank from the start which account holds the escrow, in what currency, and how released funds travel back to the relevant partys investment capital account. An escrow agreement copied from a foreign template without checking Vietnamese payment channels can easily be refused operation by the bank on closing day.
Applying the Rules to a Real Deal
On size, escrow retentions in Vietnamese company acquisitions commonly run around one tenth to one fifth of the purchase price, depending on the risk level diligence uncovered: a clean target with a substantial corporate seller supports a lower retention; a small or mid-sized company with individual sellers and a complex tax history supports a higher one held longer, typically 12 to 24 months matching the main warranty claim period. Some deals split two escrow layers: a general layer for overall warranties, and a specific layer tied to one identified risk, released when that risk is resolved whether earlier or later than the general layer.
The release mechanism is the heart of the escrow and must be written as a process, not a sentence. The agreement should specify: each partial release event, the documents proving it, who confirms, the deadline for the bank to transfer after receiving a complete set, and what happens if the buyer lodges a disputed deduction claim: the undisputed part is released immediately, the disputed part stays blocked pending joint agreement or an arbitral award. It should also provide for a seller losing legal capacity, entering bankruptcy, or a buyer change of control during the escrow period, so the bank always has clear instructions on who may order a release.
Illustrative example: A Korean strategic buyer acquired 80 percent of a Vietnamese furniture exporter and placed 12 percent of the price in a 15-month escrow for social insurance and tax warranties. In month eight, a social insurance audit assessed arrears for the pre-closing period. The escrow terms allowed the buyer to set off the assessed amount it paid on the companys behalf directly against the blocked funds, supported by the authority decision, without negotiating with the sellers who were two individuals then in a dispute between themselves. The balance was released on schedule at month fifteen.
Procedure and Documents to Prepare
First: identify the risks to be secured from diligence findings to size the escrow percentage and period properly. Next: choose the escrow bank and agree an account structure compatible with the foreign investor investment capital account. After that: draft the tripartite escrow agreement with release process, document set, set-off mechanics and disputed amount handling. Then: fund the escrow account on closing day as an item on the closing checklist. Finally: monitor release milestones and deduction claims within their deadlines, verifying documents before signing each partial release confirmation.

Common Risks and How to Prevent Them
The first risk is an escrow agreement vague on release conditions, turning the security itself into a new source of dispute. The second risk is a blocked account structure incompatible with investment capital account rules, so the bank cannot operate it on closing day. The third risk is an escrow period shorter than the warranty claim period or the tax audit cycle, expiring before the risk appears. The safeguard is tying escrow size and duration to the diligence risk map, writing the release process as a checklist, and pre-confirming operability with the escrow bank.
Escrow only works when its size and duration are tied to the risk map drawn from due diligence, not to a percentage picked out of habit. Write the release process as a checklist and confirm it with the escrow bank in advance, so the funds are not stuck on administrative grounds after the risk has passed.
Frequently Asked Questions
How does escrow in an M&A deal protect the foreign buyer?
Escrow protects the buyer by turning the sellers indemnity promise into real money held outside the sellers control. When a warranty breach surfaces, a tax assessment lands for the pre-closing period, or a specific seller obligation remains unfinished, the buyer sets off directly against the blocked funds under the agreed process, instead of chasing money from a seller who may have spent the proceeds or left Vietnam. For a foreign buyer this layer matters especially, because enforcing a favourable judgment across borders is always slower and costlier than setting off against a local escrow.
What percentage of the deal value is usually placed in escrow?
There is no statutory percentage; market practice in Vietnamese company acquisitions commonly retains around 10 to 20 percent of the price, higher where diligence found major tax or land risks, and lower where the seller is a reputable organisation with a parent guarantee partly substituting. The retention period commonly runs 12 to 24 months, matched to the main warranty claim window. The right way to size it is from the risk map: add the quantified exposures, add a margin for unquantified ones, then negotiate the percentage on that basis rather than haggling by feel.
Which banks in Vietnam provide escrow services?
In Vietnam, blocked account services supporting M&A escrow are offered by authorised commercial banks, including major domestic banks and foreign bank branches with corporate and investment banking desks. The buyer should prefer the bank already holding its investment capital account relationship, because transaction document checks and release coordination then run through a single point. Points to confirm with the bank in advance are whether it will operate a document-based release mechanism as drafted, the escrow currency, service fees, and release processing time. That confirmation should exist before the purchase agreement is signed.
