A practical guide to warranties, indemnities and W&I insurance in an Asia deal

A cross-border acquisition closing through Hong Kong or a regional offshore centre can unravel on a single clause. The target's Mainland subsidiary has undisclosed tax liabilities. The BVI holdco's constitutional documents were never updated after a restructuring. A Cayman seller is gone by the time the breach surfaces. In-house counsel at the acquiring group faces a familiar triangulation: how to allocate known and unknown risk, how to back that allocation with a payment covenant that actually works, and whether insurance can carry the residual exposure the seller will not accept. The answer depends less on negotiation leverage than on the architecture of the deal documents and the sequence in which they are built.

Warranties and indemnities in an Asia deal are contractual risk-allocation mechanisms governed by the law chosen by the parties, typically English or Hong Kong law, with W&I insurance (warranty and indemnity insurance, a policy that transfers seller-side or buyer-side warranty risk to an insurer) available to cover the gap between what the seller will stand behind and what the buyer needs. Under Hong Kong's common-law system, the enforceability of both the contractual protections and the insurance policy depends on the alignment of governing law, the deal vehicle, and the enforcement route across each relevant jurisdiction.

This guide sets out the decision the buyer's in-house counsel faces, the options on the table, the sequence in which each step is taken, and the points at which the route is commonly lost.

What decision does the reader actually face at the start of a deal?

The fundamental question is which risks the seller will accept contractually, which the buyer must bear, and which a third party – an insurer – can price and carry. Those three buckets are not determined by market convention alone. They are determined by the deal's structural facts: the jurisdiction of the target, the nature of the business, the depth of the data room, and the seller's willingness to remain exposed after closing.

In an Asia deal, the structural facts add layers that a domestic transaction does not face. A target with a variable interest entity (VIE) structure (an arrangement used by some Mainland-China-connected businesses to give foreign investors economic exposure to regulated sectors) carries warranty risk that is qualitatively different from a straightforward share purchase of a Hong Kong operating company. A target held through a BVI or Cayman entity imposes an enforcement question on top of the substantive warranty question: if the seller is an offshore vehicle with no ongoing assets after the sale proceeds are distributed, a contractual warranty is only as good as the ability to recover against it.

The first decision is therefore not about the text of the warranty schedule. It is about the deal architecture. What is being acquired, where does it sit, who is the seller entity, and what jurisdiction will govern the claim if a breach is discovered eighteen months after closing?

What are the core instruments and how do they differ?

A warranty (a statement of fact about the target made by the seller at signing and, usually, at closing) and an indemnity (a promise to pay, pound for pound, against a specific defined liability) operate differently under common law and the difference matters when calculating loss and managing time limits.

A warranty claim is a damages claim. The measure of recovery is the difference between the value of what was acquired as warranted and the value of what was actually acquired. It requires the buyer to prove loss. An indemnity, by contrast, is a payment obligation triggered by a defined event – typically a specific known risk, such as a pre-closing tax liability or litigation – and does not require a damages calculation. That distinction drives the negotiation: sellers prefer warranties because they limit recoverable loss; buyers prefer indemnities on known risks because recovery is direct.

The warranty schedule in an Asia deal typically covers title and capacity, the target's financial statements, tax compliance, material contracts, regulatory licences, employment, property, litigation, and environmental matters. Where the target has Mainland China operations, the schedule must also address PRC regulatory compliance, corporate approvals under PRC law, and, where relevant, the status of any intra-group arrangements. These points are rarely covered adequately by a precedent drawn from a London or New York transaction.

W&I insurance steps in as a third instrument. A buy-side W&I policy (written in favour of the buyer, allowing the buyer to claim directly against the insurer without first pursuing the seller) has become the more common structure in Asia. It allows the seller to achieve a clean exit, shifts the recovery burden to an insurer with assets and a claims process, and can extend the limitation period beyond what the seller would accept contractually. A sell-side policy (indemnifying the seller against a buyer's warranty claim) is less common but remains used where the seller insists on a cap that the buyer will not accept without recourse.

How does the Hong Kong and cross-border interface shape the documents?

Hong Kong law is the governing-law choice for a significant share of regional M&A. The common-law system, the clarity of its damages principles, and the accessibility of the Court of First Instance for contractual disputes all support that preference. Where the target has Mainland operations and the deal is structured above Hong Kong, the sale and purchase agreement will typically be governed by Hong Kong or English law, while PRC-specific ancillary documents – joint-venture approvals, asset-transfer agreements, regulatory filings – are governed by PRC law and handled by PRC-qualified counsel.

That split creates a drafting gate. The warranty schedule must accurately reflect what the seller actually owns and controls at each level of the structure. A warranty that the target "holds all regulatory licences required for its business" is meaningful at the Hong Kong holding company level. Whether it captures a missing PRC business licence or an unlicensed activity in a Mainland subsidiary depends entirely on how the schedule defines the group and the relevant regulatory regime. In our cross-border practice, the mis-match between the scope of the warranty and the scope of the target group is one of the most common structural errors we see in deals that arrive for enforcement advice after closing.

For enforcement, the applicable instrument for recognising a Hong Kong court judgment in the Mainland is the Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance (Cap. 645), which came into force on 29 January 2024. A claim under the sale and purchase agreement that results in a Hong Kong court judgment can, subject to the exclusion list under that ordinance, be registered with the relevant Mainland court for enforcement. That route is not available for arbitral awards, which follow the 1999 Arrangement and the 2020 Supplemental Arrangement between the Mainland and the HKSAR. The choice between a court clause and an arbitration clause in the sale and purchase agreement therefore has direct enforcement consequences if the seller or target assets are on the Mainland side of the border.

Where the seller is a BVI or Cayman entity, the enforcement question is different again. Offshore holding companies have no assets post-completion. The buyer's practical recovery route, absent W&I insurance, is to require that the seller leave a proportion of the consideration in escrow for the warranty period, or to negotiate a parent-company guarantee from a solvent entity in the seller's group. A retention mechanism (a portion of the purchase price withheld in a third-party escrow account and released on satisfaction of conditions) and a guarantee are both common in Asia deals where the seller lacks a durable balance sheet.

What is the practical sequence, and where are the gates?

Step one is the disclosure exercise. The seller prepares a disclosure letter (a document delivered at signing that qualifies the warranties by reference to specific facts known to the seller). The buyer's counsel reviews the data room, prepares a warranty questionnaire, and maps the resulting disclosures against the warranty schedule. Any gap between what the schedule covers and what the disclosure letter qualifies is the buyer's residual risk.

The first gate is the adequacy of the data room. A thin data room means that the seller cannot make many specific disclosures and is instead relying on general disclosures – references to publicly available information or documents in the data room. In Asia deals, general disclosures are common and their scope is hotly negotiated. The buyer's counsel should restrict general disclosures to documents that are actually accessible and that a reasonable buyer's adviser would have reviewed.

Step two is the scope and basket negotiation. The seller will seek a de minimis threshold (a floor below which individual claims are disregarded) and an aggregate basket (a minimum total below which the buyer cannot bring a claim at all). Above the basket, the seller will seek a cap, typically expressed as a percentage of the purchase price. In Asia deals, the basket and cap levels reflect the nature of the target and the depth of the disclosure. For a deal going to W&I insurance, the insurer's minimum retention and the policy excess will influence what the buyer is willing to accept on the contractual side.

Step three is the W&I underwriting process. The insurer receives the disclosure bundle – the sale and purchase agreement, the disclosure letter, the data room index, and any vendor due-diligence reports – and conducts a non-disclosure agreement-protected underwriting call (a confidential call between the insurer's counsel and the buyer's deal team to walk through the diligence findings and the key warranty risks). The underwriter will identify exclusions: matters specifically known to the buyer, known deal risks disclosed by the seller, and, frequently in Asia transactions, PRC regulatory compliance and title to Mainland assets. Those exclusions must be mapped back to the warranty schedule so that the buyer understands what the policy does not cover.

The second gate is the alignment of the policy scope with the contractual scope. A buy-side W&I policy that excludes the same matters that the seller has already excluded from its warranty cover leaves the buyer carrying those risks on both the contractual and the insurance side. The buyer's counsel should audit this alignment before committing to the policy terms.

Step four is the limitation period. Under Hong Kong law, the standard limitation period for a simple contract is six years from breach. The parties are free to contractually shorten this. Sellers in Asia deals commonly push for a two-year general warranty period and a five-to-seven-year tax warranty period. A W&I policy will have its own policy period, which may match or extend the contractual period. The buyer should check that the policy period and the contractual period align: a claim notified within the policy period but after the contractual period has expired may be recoverable under the policy only if the insurer agrees to the extension – and that agreement must be in the policy language, not in a side letter.

Step five is the indemnity schedule. Specific known risks identified during due diligence – a tax audit under way in the Mainland subsidiary, a pending regulatory inquiry, a disputed earnout from a prior acquisition – should be separately indemnified rather than absorbed into the general warranty cover. The indemnity is triggered by the occurrence of the defined liability. It is not subject to the basket or the cap that applies to the warranty claims, unless the parties expressly agree otherwise.

The third gate is the definition of the indemnified event. A poorly drafted indemnity can be defeated by a seller's argument that the liability arose from post-closing actions of the buyer or the target group. Counsel on our desk regularly sees indemnities where the trigger event is defined at too high a level of generality, allowing the seller to argue that the post-closing conduct of the target breaks the causal chain. The fix is precise drafting: the indemnity should identify the specific proceeding, the specific tax period, or the specific regulatory matter by reference to documents in the data room.

The sequence described above applies to a standard share acquisition. For an asset deal, the warranty and indemnity structure shifts because the buyer is not inheriting the liabilities of a corporate entity but is acquiring specific assets with specific warranties as to title and condition. The enforcement question also shifts: the buyer's recourse is against the seller of the assets, and the relevant contractual and tortious mechanisms depend on the governing law of the asset-transfer agreement.

The sequence above describes the standard position. Your matter turns on the documents, the jurisdictions actually engaged, and the order of steps – which is where the route is won or lost.

What are the most common mistakes in an Asia deal context?

The most common error is treating the warranty schedule as a generic checklist rather than a document calibrated to the target structure. A schedule lifted from a European precedent and applied to a Mainland-connected target will typically miss the PRC corporate governance approvals, the registered capital position of each PRC subsidiary, the status of related-party transactions under PRC foreign investment rules, and the standing of the target under the relevant PRC sectoral licences. These are not minor drafting points. Each one is a potential indemnity exposure that the schedule fails to convert into a contractual right.

The second common error is underestimating the interaction between the disclosure letter and the W&I policy. A seller who discloses broadly – relying on the general disclosure of the entire data room – may effectively read down the warranty schedule to the point where the residual undisclosed risk is small but the W&I insurer excludes the same broad categories. The buyer holds a policy that covers the gap between the warranty and the disclosure, but the disclosure letter has already closed most of the gap. The buyer's counsel should review the scope of general disclosures against the policy exclusions before agreeing the disclosure letter form.

The third error is sequencing the W&I process too late. W&I underwriting takes time, and the insurer needs to review the final or near-final disclosure bundle. Starting the underwriting process after the disclosure letter is finalised means that exclusions discovered during underwriting can no longer be addressed in the warranty negotiation. The underwriting process should run in parallel with the disclosure and warranty negotiation, not after it.

What foreign counsel most frequently miss in an Asia deal is the enforcement tail. A warranty claim that cannot be prosecuted efficiently – because the governing law of the sale agreement is misaligned with the forum clause, or because the seller entity will have no assets after completion – is a paper right. The document architecture must anticipate enforcement from the start.

A mid-market acquisition in autumn 2025 illustrates the structural point. An Asian industrial group acquired the shares of a Cayman holdco with a single Mainland subsidiary. The sale and purchase agreement was governed by Hong Kong law with a Hong Kong arbitration clause. The seller was the Cayman holdco's sole shareholder. No escrow was agreed; no parent guarantee was taken. A tax indemnity claim arose eight months post-closing. By that point, the sale proceeds had been fully distributed. The arbitration clause was unimpeachable; the enforceability of any award against the seller was theoretical. We were instructed at the arbitration stage. The practical outcome depended on tracing assets held by the seller's parent in a third jurisdiction – a step that added cost and time that a modest contractual adjustment at closing could have avoided entirely.

If an earlier filing, structure, or enforcement attempt produced an adverse or stalled result, a second read can identify the strategic error and the routes still open. Contact us at info@lockhartyip.com.

How does W&I insurance interact with the deal structure in practice?

W&I insurance in Asia has matured considerably. The product is now available on transactions involving targets with significant Mainland operations, BVI or Cayman holding structures, and mixed asset/share deal profiles. The market, however, retains a distinct exclusions profile for Asia transactions that differs from what a European or North American buyer may expect from a comparable deal in those markets.

Standard exclusions in an Asia W&I policy frequently include: known PRC regulatory violations disclosed in the data room; title to Mainland land-use rights where the underlying documentation is incomplete; VIE-structure enforceability risk; and any tax liability arising from a Mainland tax audit that is already in progress at the time of underwriting. None of these exclusions is universal – a careful buyer's counsel can negotiate narrower carve-outs depending on the diligence record – but they represent the default starting position of most underwriters active in the region.

The practical implication is that W&I insurance in an Asia deal is not a substitute for rigorous due diligence. It is a complement to it. The buyer who treats the insurance as a reason to do less diligence will find that the insurer's exclusions track the gaps in the data room precisely. A thorough diligence exercise, by contrast, allows the buyer's counsel to negotiate exclusions down and to ensure that genuinely unknown risks – the risks that insurance is designed to cover – are within the policy scope.

Insurers also look closely at the disclosure process. A buyer who has not read the data room carefully, or who has relied on a vendor due-diligence report without independent verification on key points, will face underwriters unwilling to write broad cover. In our cross-border practice, we coordinate the diligence workstream with the insurance underwriting process to ensure that the level of knowledge attributed to the buyer is accurate and that the policy exclusions are genuinely limited to matters the buyer has reviewed and accepted.

For deals involving a mix of Hong Kong-listed, offshore-held, and Mainland-operating assets, the W&I policy should ideally cover the entire perimeter of the target group. A policy that covers the Cayman holdco warranties but not the PRC-law representations in the ancillary PRC transaction documents leaves a structural gap. The buyer's counsel should confirm with the insurer whether the policy extends to representations and warranties made in documents governed by laws other than the governing law of the main sale and purchase agreement.

Decision checklist: what to confirm before proceeding

The following checklist is not exhaustive. It is a set of threshold confirmations that in-house counsel and their external advisers should complete before the warranty and indemnity structure is finalised.

Deal architecture: Has the target group perimeter been confirmed, including all PRC subsidiaries, offshore holding entities, and any VIE-structure components? Does the definition of the target group in the sale agreement match the entities for which warranties are being given?

Governing law and forum: Is the governing law of the sale agreement consistent with the forum clause? Has the enforcement route been mapped for each jurisdiction in which the seller or the target holds assets? For Mainland enforcement, has the applicability of the reciprocal-enforcement regime under Cap. 645 been confirmed, or has an arbitration-based enforcement route been chosen?

Seller credit risk: If the seller is an offshore entity, what assets will it hold after completion? Is an escrow, a retention, or a parent guarantee needed to back the warranty obligations? If W&I insurance is used, does the policy limit make the seller's direct liability irrelevant for most realistic claim scenarios?

Disclosure letter scope: Have general disclosures been limited to documents actually reviewed by the buyer's team? Has the disclosure letter been reviewed against the W&I policy exclusions to confirm that the policy covers the residual undisclosed risk?

Indemnity schedule: Have all specific known risks been identified and indemnified separately from the general warranty cover? Is each indemnity trigger defined precisely enough to survive a post-closing causation argument?

W&I underwriting timing: Has the underwriting process been started early enough to allow policy exclusions to be addressed in the warranty negotiation? Has the policy period been confirmed to align with or extend the contractual warranty period?

PRC-specific coverage: Have the PRC regulatory compliance warranties been reviewed by PRC-qualified counsel? Are the material PRC matters – tax, licensing, land, related-party transactions – each addressed either in the warranty schedule, the indemnity schedule, or the W&I exclusions with a full understanding of what is and is not covered?
