Warranties, indemnities and W&I insurance in an Asia deal: a step-by-step guide

A deal that closes on time, with full consideration paid and no post-closing claims, is the outcome every principal wants. In Asia, particularly where the target has operations or assets in Mainland China and the acquisition vehicle sits in Hong Kong, the BVI or the Cayman Islands, the allocation of risk between buyer and seller is rarely straightforward. The seller wants a clean exit. The buyer wants protection against what it did not know. W&I insurance – warranty and indemnity insurance (a product that transfers the financial exposure under a seller's representations and warranties to a specialist insurer) – has become a standard tool in mid-market and large-cap Asia transactions. Yet the sequence in which the risk-allocation documents are negotiated, and the point at which the insurer enters the process, determines whether the policy actually responds when something goes wrong.

In an Asia cross-border deal, warranties, indemnities and W&I insurance operate as a three-layer risk-allocation system: the seller's representations and warranties in the sale and purchase agreement form the first layer; specific indemnities address identified risks uncovered in due diligence; and a buy-side W&I policy, placed under the governing law of the deal documents (typically English law or Hong Kong law), transfers the financial exposure on warranty breaches to the insurer. The sequence matters because a policy placed after the fact – or drafted without reference to the underlying representations – is likely to exclude the exposures that matter most.

This guide sets out the steps in order, identifies the gate that must be cleared at each stage, flags the single most common mistake, and offers a short decision checklist for in-house counsel preparing for an Asia deal.

Why does risk allocation look different in an Asia deal?

Risk allocation in any M&A transaction is ultimately a question of information asymmetry: the seller knows the business; the buyer does not. In an Asia transaction, that asymmetry is sharpened by three structural features that do not commonly appear together in a European or North American deal.

First, the target is frequently organised across multiple layers – a holding entity in an offshore centre (most often the BVI or the Cayman Islands), an intermediate holding company in Hong Kong, and one or more operating entities in Mainland China structured as wholly foreign-owned enterprises (operating subsidiaries under PRC law, often referred to as WFOEs) or joint-venture companies. Each layer is governed by a different legal system. A warranty that is enforceable as written under English law may be interpreted differently before a people's court in the Mainland.

Second, due diligence on Mainland assets is constrained. Access to state-held registers, audited financials and regulatory approvals can be incomplete. The buyer's information base is narrower than it would be for a comparable European target. That compression drives demand for broader warranty coverage – which in turn creates friction with a seller who has limited visibility into its own historical compliance position.

Third, exit mechanics differ. A seller backed by a private equity fund – or a founder seeking a clean departure to a new venture – has a structural reason to refuse a large escrow. W&I insurance resolves that tension: the seller gives the warranties, the insurer provides the financial backstop, and the escrow is reduced or eliminated. In our cross-border M&A practice, this dynamic is the primary driver of W&I adoption in the region.

What does that mean for the buyer's counsel? It means the policy must be placed on the basis of a due-diligence exercise that is, as far as possible, complete. An insurer underwriting an Asia buy-side policy will read the due-diligence reports with the same scrutiny as the buyer's advisers. Gaps will become exclusions.

Step 1: Agree the deal structure and the governing law before drafting any warranty schedule

The first gate is structural: before any warranty is drafted, the parties – and their counsel – must agree the acquisition vehicle, the governing law of the sale and purchase agreement, and the jurisdiction of dispute resolution. These choices constrain every downstream risk-allocation decision.

In a Hong Kong-led acquisition of a PRC operating group, the typical structure involves a share purchase at the offshore or Hong Kong intermediate level. The sale and purchase agreement is almost invariably governed by English law or Hong Kong law – which, for these purposes, are materially identical in their treatment of representations and warranties. The governing law determines how warranty claims are characterised, how consequential loss is assessed, and what remedy is available if a warranty is untrue.

Governing law is also the threshold question for W&I insurers. Most institutional insurers writing Asia policies are comfortable with English-law or Hong Kong-law governed documents. A deal structured under PRC law, or with a PRC-court jurisdiction clause, will face significant underwriting resistance – or will require a separate structuring layer to bring the warranty and indemnity documents into an acceptable legal environment.

The practical gate at Step 1: the acquisition structure, the governing law of the transaction documents, and the dispute-resolution clause must all be agreed and documented before the warranty schedule is prepared. Running the warranty negotiation in parallel with an unresolved structural question is a common source of delay and mismatch. For a detailed analysis of structuring the acquisition vehicle, see our matter note on structuring an acquisition vehicle for a Greater China deal.

Step 2: Conduct the due diligence and record findings systematically

The W&I policy is underwritten on the basis of the due-diligence process. This is not a background point. It is the central underwriting premise: the insurer is asked to take on the risk that the seller's warranties are untrue, in circumstances where the buyer has conducted a reasonable investigation and not discovered the breach. If the due diligence was incomplete, poorly documented, or not shared with the insurer in its entirety, the claim may fail at the coverage stage.

What constitutes adequate due diligence in an Asia transaction? At minimum: legal due diligence on the target group's corporate structure, title to assets and material contracts; financial due diligence on the audited accounts; tax due diligence covering PRC enterprise income tax, indirect taxes and any cross-border related-party arrangements; and regulatory due diligence on licences, permits and sector-specific approvals. For targets with Mainland operations, that last category includes any approvals required under PRC foreign-investment rules.

The W&I insurer will appoint its own counsel to review the due-diligence reports and the warranty schedule in parallel. The insurer's counsel will identify matters disclosed in the reports but not reflected in the disclosure letter or the warranty schedule. Those matters will almost certainly be excluded from coverage. The buyer should therefore ensure that any matter that affects the purchase price or the decision to proceed is addressed either in the warranty schedule or through a specific indemnity – not left as a due-diligence finding without a contractual home.

A micro-scenario illustrates the point. A European industrial group acquired a Mainland manufacturing business through a BVI holdco, with the sale and purchase agreement governed by English law and Hong Kong as the dispute-resolution seat (autumn 2026). The tax due-diligence report identified a potential permanent establishment exposure (a taxable presence in a jurisdiction arising from the activities of personnel or agents) in a second Mainland province. The exposure was noted in the report but not raised as a specific indemnity claim during negotiation. The W&I policy excluded it as a known risk. When the provincial tax authority raised an assessment post-closing, the buyer had no policy cover and no indemnity. The seller had given a general tax warranty, but the disclosure letter referred to the due-diligence report as a whole. Counsel on our desk see this pattern regularly: the gap between a due-diligence finding and a negotiated indemnity is where post-closing exposure lives.

Step 3: Negotiate the warranty schedule and the disclosure letter together

The warranty schedule and the disclosure letter are two sides of the same document. A warranty creates the obligation; a disclosure qualifies it. In practice, many deals treat them as sequential – the seller's counsel drafts the disclosure letter after the warranty schedule is agreed. That sequence is the second common source of post-closing disputes.

The gate at Step 3: the warranty schedule and the disclosure letter should be negotiated concurrently, and the scope of general disclosures should be agreed before the insurer conducts its underwriting call. Insurers in Asia deals typically do not accept general disclosures that sweep in an entire data room without specification. A well-structured disclosure letter identifies specific matters against specific warranties. That specificity protects the seller from a warranty claim; it also gives the insurer a clear picture of what the policy does and does not cover.

For an Asia deal, the warranty schedule should address at minimum: corporate title and authority; financial statements and accounting policies; tax warranties (structured to cover both Hong Kong and PRC tax positions); material contracts and change-of-control provisions; employment and labour compliance (PRC labour law is strict on redundancy, social insurance and housing provident fund contributions); regulatory licences; environmental matters; and intellectual property. Each category should be drafted by reference to the governing law of the sale and purchase agreement – not by reference to the legal system of the jurisdiction where the risk sits, unless that is also the governing law.

The indemnity schedule sits alongside the warranty schedule. Indemnities are different in character: they respond to identified, specific exposures rather than to the general truth of a representation. A specific indemnity for a pre-closing tax liability in the Mainland, for example, operates on a dollar-for-dollar basis; it does not require the buyer to prove loss in the same way as a warranty claim. In practice, anything identified in due diligence as a quantifiable risk should be the subject of a specific indemnity rather than a warranty, because the coverage threshold and the proof burden are lower.

Step 4: Approach the insurer at the right point in the process

W&I insurers operating in Asia expect to be approached after the due-diligence process is substantially complete and the near-final warranty schedule is available for review – but before signing. Approaching the insurer too early, before the due-diligence reports are finalised, means underwriting is conducted on an incomplete information base and the policy will carry broader exclusions. Approaching the insurer after signing means the underwriting review cannot affect the warranties agreed, and any exclusions the insurer imposes will create gaps the buyer cannot remedy.

The standard process: the buyer's adviser approaches one or more W&I brokers once the data room is substantially populated and the first draft of the warranty schedule is available. The broker prepares a non-binding indication, which gives the buyer a preliminary view of coverage scope, exclusions and premium range. The buyer then selects an insurer – or runs a limited competitive process – and the insurer's underwriting team reviews the due-diligence reports and the warranty schedule. An underwriting call (usually one to two hours) follows, at which the buyer's counsel and the due-diligence advisers present their work to the insurer and address questions.

The gate at Step 4: the insurer must have access to the complete due-diligence reports, the near-final warranty schedule, and the disclosure letter in its current form. Anything withheld from the insurer at this stage is a potential basis for a coverage denial at claim stage. The duty of disclosure to the insurer is not merely a formality; it is the contractual foundation on which the policy is written.

In the Hong Kong and Asia market, buy-side policies are standard. The buyer is the insured; the seller is released from financial exposure (save for fraud). The policy period typically runs for three to seven years for general warranties and up to ten years for fundamental warranties, tax warranties and specific indemnities – though the precise terms vary by insurer and deal profile. Verify the current market standard for the specific deal before committing.

Step 5: Align the policy terms with the sale and purchase agreement

The single most common mistake in W&I placement on Asia deals is a mismatch between the policy terms and the underlying sale and purchase agreement. The policy must mirror the sale and purchase agreement in three respects: the definition of warranty breach; the applicable limitation provisions (caps, baskets, time limits on claims); and the definition of loss. Where these definitions diverge, a claim that is successful under the sale and purchase agreement may not be covered by the policy.

Consider the limitation provisions. A buyer-side policy will typically apply a retention (analogous to an insurance excess) below which the insurer does not respond. The retention is set by reference to the deal value – commonly in the range of a fraction of one per cent of enterprise value for larger transactions, though the market moves. The sale and purchase agreement should contain a de minimis and an aggregate threshold that are calibrated to the retention. If the sale and purchase agreement basket is set below the policy retention, claims that clear the contractual basket but fall below the retention will fall into a gap. Counsel on our desk address this alignment exercise as a standard step before signing.

Time limits are the second mismatch point. The sale and purchase agreement may impose a limitation period for warranty claims (typically eighteen months to three years for general warranties). The policy must match or exceed that period. Where the policy expires before the contractual limitation period, the buyer is exposed to warranty claims it cannot pass through to the insurer.

The alignment exercise should be conducted by the buyer's counsel in conjunction with the W&I broker before the policy is bound. The broker's role at this stage is not merely administrative; an experienced broker will identify mismatches between the draft policy wording and the sale and purchase agreement and negotiate corrections with the insurer before the policy is placed.

For buyers with a portfolio of Asia transactions, or for corporate groups structuring a joint venture alongside an acquisition, the interface between the warranties in the sale and purchase agreement and any joint-venture or shareholders' agreement is a further alignment point. See our analysis of joint-venture structuring between a foreign investor and a Singapore partner for the related cross-border considerations.

Step 6: Address the cross-border enforcement dimension

A W&I policy written under English law and providing for arbitration in Hong Kong is only as useful as the mechanism available to enforce an award if the insurer disputes the claim. For most institutional W&I insurers operating in the Asia market, this is not a live issue: the insurer is a rated entity with assets in accessible jurisdictions, and a Hong Kong or Singapore arbitral award can be enforced against those assets directly.

The enforcement question is more acute for the underlying warranty claim itself – specifically, where the seller is a PRC entity or individual and the buyer intends to fall back on the contractual warranty if the W&I policy does not respond. In that scenario, the Hong Kong enforcement position matters. The Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance (Cap. 645) came into force on 29 January 2024, replacing the earlier choice-of-court mechanism. Under Cap. 645, an effective judgment of a Mainland court may be registered with the Court of First Instance and enforced in Hong Kong, and vice versa – subject to the exclusions and connection-based criteria set out in the Ordinance.

For warranty claims resolved by Hong Kong arbitration – which is the market standard in Asia deals – the mutual-enforcement arrangements between Hong Kong and the Mainland provide a route to enforce an award against Mainland assets. The Interim Measures Arrangement, in effect since 1 October 2019, allows a party to a Hong Kong-seated arbitration to apply to a Mainland people's court for interim measures before and during the arbitration. That mechanism is directly relevant where a seller's Mainland assets may be dissipated before an award is made.

The practical gate at Step 6: before signing, the buyer's counsel should map the enforcement route against the seller's actual assets. Where the seller is a Mainland entity or individual, the arbitration clause should specify Hong Kong as the seat, the arbitration rules should be selected by reference to an institution whose awards are enforceable in the Mainland under the existing Arrangements, and the agreement should contain appropriate asset-disclosure and preservation provisions.

Our M&A & Transactions practice covers the full transaction cycle, including pre-signing due diligence, structuring, warranty and indemnity negotiation, and post-closing enforcement.

Step 7: The decision checklist for in-house counsel

The following checklist summarises the gates at each step. It is not a substitute for legal advice on a specific transaction, but it provides a starting framework for in-house counsel briefing external advisers or preparing a transaction committee presentation.

• Structure agreed before warranty drafting? The acquisition vehicle, the governing law of the sale and purchase agreement, and the dispute-resolution mechanism should all be fixed before the warranty schedule is prepared. A Hong Kong or English governing-law document provides the most reliable foundation for W&I placement.
• Due diligence complete and documented? Legal, financial, tax and regulatory due diligence should be complete, and the reports should be in final or near-final form before the insurer is approached. Gaps in due diligence become exclusions in the policy.
• Warranty schedule and disclosure letter negotiated concurrently? General disclosures should be specific; a sweep of the data room as a whole will not be accepted by most institutional W&I insurers and creates uncertainty about the scope of cover.
• Specific indemnities identified for quantifiable due-diligence findings? Any risk identified in due diligence that can be quantified should be addressed by a specific indemnity, not left as a warranty. Tax exposures in the Mainland are the most common category in our experience.
• Insurer approached at the right stage? The non-binding indication should be obtained once the warranty schedule is in near-final form and the due-diligence reports are substantially complete. Do not approach the insurer before due diligence is substantively done.
• Policy terms aligned with the sale and purchase agreement? The retention, the basket, the time limits and the definition of loss must be consistent between the policy and the underlying agreement. The alignment exercise should be completed before signing.
• Enforcement route mapped? Where the seller has Mainland assets, the arbitration clause should specify Hong Kong as the seat, and interim-measures options should be considered. Where the sale and purchase agreement produces a judgment (rather than an award), the Cap. 645 registration mechanism is the primary enforcement route.
• Tax and regulatory clearances obtained? In a Mainland-target deal, foreign-investment approvals, foreign-exchange registration, and any merger-control filings must be obtained before or at closing. A W&I policy does not substitute for a missing regulatory clearance.

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 foreign counsel and in-house teams commonly misread

Cross-border deals involving a Hong Kong hub and Mainland assets are handled regularly by counsel whose primary expertise is in one of the jurisdictions, not across the interface. Three misreads appear often enough to deserve specific mention.

The first is treating a Hong Kong intermediate holding company as equivalent to a Mainland-law entity for warranty purposes. The warranties in the sale and purchase agreement run to the seller's actual knowledge of the business. A seller who holds the target through a Hong Kong intermediate company may not have direct knowledge of matters at the operating-company level. The knowledge-qualifier in the warranty schedule must be calibrated to the actual information architecture of the group – not assumed to run all the way down to the WFOE.

The second misread is underestimating the PRC employment and social-insurance dimension. Mainland operating companies are subject to mandatory social insurance and housing provident fund contributions for all employees. Under-contribution is common in practice and is a frequent W&I claim trigger. A buyer that relies on a general tax warranty to cover this exposure – rather than a specific indemnity or a dedicated due-diligence sign-off – is likely to find the warranty claim resisted on knowledge-qualifier or disclosure grounds.

The third misread is treating the W&I policy as a substitute for negotiating the warranties. The policy covers what the warranties say. If the warranty is too narrow, the policy will not expand it. Buyers sometimes accept compressed warranty schedules on the assumption that the W&I insurer will fill the gaps. That assumption is wrong. The insurer underwrites the warranties as drafted; it does not underwrite risk that was never warranted.

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. To discuss a specific cross-border position, write to us at info@lockhartyip.com.
