Reading the risk in asset protection for a principal with Mainland China exposure

Asset protection for a principal with Mainland China exposure turns on a specific and underappreciated question: what legal system will actually govern your assets when a claim arises, and does your current structure answer that question before the claim does? The governing instruments are the Trustee Ordinance (Cap. 29) in Hong Kong – substantially reformed with effect from 1 December 2013 – and the succession, matrimonial, and enforcement regimes of the Mainland. The interface between them is where the real exposure sits, not in any single jurisdiction's rules read in isolation.

This analysis maps the risk, names the mechanisms that matter, and gives a practitioner's read on where the structural weaknesses concentrate for a principal with assets, family, or counterparties on both sides of the boundary.

What is actually at stake commercially?

The question we most often hear from a principal in this position is not "how do I hide assets." It is something more precise: "if something goes wrong – a business dispute, a divorce, a succession event, a regulatory investigation – what happens to the assets I have built?" That is the right question. The answer depends on jurisdiction in a way that most principals do not fully appreciate until the event has occurred.

A Mainland-connected principal typically holds assets across several systems simultaneously. There may be operating companies in the Mainland, a Hong Kong holding entity, offshore vehicles in the British Virgin Islands or the Cayman Islands, and real property scattered across multiple jurisdictions. The family may have residence in more than one place. The succession instruments, if any exist, were often prepared in one jurisdiction without regard to how they interact with the others.

What is at stake commercially is not abstract. Enforcement of a Mainland judgment in Hong Kong is now materially faster and wider than it was before the Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance – commonly referred to as Cap. 645 – came into force on 29 January 2024. A creditor who holds an effective Mainland judgment can now apply to register it with the Court of First Instance without needing to show that the original court had exclusive jurisdiction over the parties. That change removes what was, for many years, a significant practical barrier to cross-boundary judgment enforcement.

For a principal whose business exposure is on the Mainland and whose assets are nominally held through Hong Kong or offshore structures, the practical consequence is direct. The structural distance between the Mainland operating entity and the family's holding assets has shortened. That is the commercial reality that drives the structuring conversation.

How does the cross-border interface actually bite?

The cross-border interface between the Mainland and Hong Kong legal systems creates three distinct pressure points for a principal in this position, and they operate on different timescales.

The first is judgment and award enforcement. Under Cap. 645, a Mainland court judgment in a civil or commercial matter that is effective under Mainland law can be registered in Hong Kong and enforced against Hong Kong-situated assets. The old requirement – that the original Mainland court must have had exclusive jurisdiction by reason of an express jurisdiction agreement – has been replaced by a connection-based test. This means that judgments arising from Mainland commercial litigation, including disputes involving a principal's operating entities, can travel to Hong Kong more readily than before.

The second pressure point is succession. Mainland law applies a forced-heirship regime. Hong Kong law does not. Where a principal holds assets in both systems, the succession outcome depends, in part, on the lex situs (the law of the jurisdiction where the asset is situated) and on the lex domicilii (the law of the principal's domicile at death). A principal who is domiciled in the Mainland, by operation of law or by fact, may find that Mainland succession rules apply to a broader pool of assets than was anticipated – including assets that were intended to pass under a Hong Kong trust or a foreign will.

The third pressure point is matrimonial. Divorce proceedings in the Mainland courts can and do result in orders affecting offshore-held assets if the court reaches the conclusion that those assets form part of the matrimonial estate. The analysis here is fact-specific. But the structural question – whether a trust, a holding company, or a foreign ownership vehicle genuinely separates the principal from the underlying assets for these purposes – is one that the structure must answer in advance, not in the middle of contested proceedings.

In our cross-border practice, we see all three of these pressure points in active matters. The enforcement one tends to move fastest. The succession and matrimonial ones tend to surface with less warning.

What does the Trustee Ordinance actually offer, and where are its limits?

Hong Kong's Trustee Ordinance, as reformed in 2013, gives a Hong Kong-law trust a set of features that make it genuinely useful in an asset-protection context. Three of them are directly relevant for a principal with Mainland exposure.

The first is the abolition of the rule against perpetuities and excessive accumulations for Hong Kong trusts. A principal can settle assets into a Hong Kong-law trust without a fixed termination date. That makes Hong Kong trusts suitable for multi-generational holding, where the primary purpose is continuity across succession events rather than any particular distribution timetable. For context on multi-generational trust structures for family groups, see our analysis at Private Trust Company: Multi-Generational Family Analysis.

The second feature is the statutory protection for settlor-reserved powers. Under the reformed Trustee Ordinance, a trust is not invalidated merely because the settlor has reserved certain powers – for example, the power to direct investments, to add or remove beneficiaries, or to revoke and resettle. This is significant because many principals who are considering a trust structure are reluctant to relinquish all control. The statutory position in Hong Kong allows a degree of retained involvement without automatically defeating the trust's protective effect.

The third, and perhaps most important for a Mainland-connected principal, is the anti-forced-heirship firewall. The 2013 reform strengthened the protection of Hong Kong-law trusts against foreign forced-heirship claims. Where Mainland law would impose a forced share on certain relatives, Hong Kong law – if it is the governing law of the trust – does not automatically import that entitlement into the trust structure.

But the limits are as important as the features. The firewall does not operate unconditionally. If a Mainland court makes an order and seeks to enforce it in Hong Kong through the mechanisms created by Cap. 645, the question becomes whether that order falls within the scope of the reciprocal enforcement regime. Matrimonial and succession matters are specifically excluded from Cap. 645's scope. That exclusion is significant: it means that a Mainland court's succession or matrimonial order does not automatically convert into an enforceable Hong Kong judgment through the registration route. However, that exclusion is not a complete answer. Other routes may be available, and the position requires careful analysis for each structure and each principal's facts.

The comparative read: where Hong Kong and Mainland rules produce different outcomes

A practitioner advising a principal across both systems quickly identifies several areas where the legal outcomes diverge materially. Understanding the divergence is the first step to structuring around it.

On succession, Mainland law allocates inheritance among a defined group of statutory heirs and imposes mandatory shares that a will cannot entirely exclude. Hong Kong law, by contrast, allows a testator to dispose of assets largely as they wish – subject to a dependants' provision regime that is procedurally different in character. A Hong Kong-law trust, holding assets that are legally situated in Hong Kong (including shares in Hong Kong-incorporated companies), can in principle operate outside the reach of Mainland mandatory succession rules. The analysis depends on whether the trust is genuine and whether the principal's domicile at death is determined to be in the Mainland or elsewhere.

On matrimonial property, Mainland law treats certain categories of property as jointly owned between spouses. Hong Kong law uses a different analysis focused on the court's discretionary powers on divorce. Where assets are held through a Hong Kong trust of which the principal is a discretionary beneficiary, the matrimonial court's reach depends on whether the trust assets can be treated as a resource available to the principal. Courts in Hong Kong have in various matters examined this question, and the outcome is not automatic in either direction. The structure of the trust – particularly the degree of retained control and the pattern of distributions – is examined carefully.

On enforcement, the position has shifted materially. Before 29 January 2024, a Mainland commercial judgment required a connection through an exclusive-jurisdiction clause to travel to Hong Kong. The new regime under Cap. 645 applies a connection-based test that the Mainland courts are more readily able to satisfy. For a principal facing commercial litigation in the Mainland, the consequence is that judgment creditors now have a more accessible route to Hong Kong-situated assets. Structures that were designed around the old enforcement barrier need to be reviewed against the new position.

What foreign advisers and principals commonly misread

The most common structural error we see is the assumption that an offshore holding layer – a BVI or Cayman company sitting above the Mainland operating entity – creates effective asset separation for all purposes. It does not, automatically.

An offshore company is a separate legal entity. But if it is entirely owned and controlled by the principal, if its sole asset is the Mainland operating business, and if it has no independent governance, then a court examining whether it constitutes an asset of the principal – for succession, matrimonial, or enforcement purposes – will look at substance, not form. The offshore layer is useful. It is not a substitute for a well-designed trust structure with genuine independence at the trustee level and a clear separation between the settlor's retained interests and the trust's proprietary position.

A second common misread is that a foreign will adequately governs all assets. A will governs what it can govern under the applicable succession law. Where assets are held in different jurisdictions, the will may not be recognised in each of them, and the terms of the will may conflict with local mandatory succession rules. A Mainland-connected principal who has only a foreign will and no trust or other holding structure should treat that as an open risk.

A third error, specifically relevant to the post-2024 enforcement environment, is the assumption that moving assets to Hong Kong after a Mainland dispute has arisen is a protective step. In some circumstances the timing of asset movements relative to the commencement of proceedings – or a creditor's knowledge of a potential claim – engages questions of transaction avoidance under the relevant insolvency or creditor-protection rules. Timing matters, and the strategy must be designed in advance of a dispute, not in response to one.

A micro-scenario: the principal who restructured too late

An Asian manufacturing group with Mainland operations and a BVI holding company held all of the principal's commercially material assets above a single intermediate layer. The trust structure that the principal's advisers had proposed several years earlier had never been implemented, largely because the principal was unwilling to relinquish the degree of control that the original draft required. When Mainland commercial litigation produced a judgment against the principal's Mainland entity in late 2025, the question of enforcement against the BVI company's Hong Kong bank accounts arose quickly under the Cap. 645 registration route.

We were engaged to review the remaining structural options. The analysis turned on two questions: first, whether the BVI company's assets were subject to the judgment-registration route in Hong Kong; second, whether a trust settlement made at that stage would be effective or would be susceptible to challenge as a transaction at an undervalue or a disposition intended to defraud creditors. The answers were not straightforward, and some of the routes that would have been available at the earlier structuring stage were no longer open.

The outcome – qualitatively – was better than the principal had initially feared, but materially worse than what would have been achievable with a structure in place at the outset. The lesson is not complicated. A Hong Kong-law trust with an independent trustee, a clear separation of the principal's retained interests, and proper governance documentation, established before a dispute arises, is a different instrument from a trust established in response to a known claim.

A second scenario: the succession event without a structure

A principal domiciled in the Mainland with a Hong Kong holding company and real property in Hong Kong passed away without a trust structure and with only a Mainland will. The Mainland will addressed the Mainland-situated assets adequately under Mainland succession law. It did not address the Hong Kong holding company's shares, and there was no Hong Kong will. The shares passed under Hong Kong's intestacy rules – which applied because there was no valid will covering them – rather than in accordance with the principal's expressed intentions.

A successor family office came to us to manage the estate administration across both systems and to consider how a trust structure could be used going forward to prevent the same outcome for the next generation. The practical analysis – which we assisted the family's legal team with across the two systems – involved identifying which assets were governed by which succession law, what the mandatory shares looked like under each system, and how a Hong Kong-law trust holding the Hong Kong assets could be structured to achieve the family's actual distributional intentions without conflicting with Mainland obligations.

This is the type of matter described in more detail in our overview of the full Private Wealth practice.

Our read on where the risk sits now

The risk profile for a Mainland-connected principal has shifted over the past two years in ways that make earlier structuring assumptions unreliable.

The reciprocal enforcement regime under Cap. 645 has reduced the structural distance between a Mainland commercial judgment and Hong Kong-situated assets. Any principal who built an asset-protection structure before 29 January 2024 and whose structure was designed around the old exclusive-jurisdiction requirement should treat that structure as requiring a formal review.

The succession risk remains persistent but is often underweighted. A principal who is effectively domiciled in the Mainland – by residence pattern, business registration, or family connection – faces mandatory succession rules that cannot be excluded by a foreign will alone. A Hong Kong-law trust with assets legally situated in Hong Kong, properly structured and documented, provides the most reliable available protection under the current legal environment. But it must be in place, and it must be genuine.

The matrimonial risk is the one most often deferred. We regularly see principals who are aware of the succession and enforcement exposures but who treat the matrimonial question as too sensitive or too speculative to address. In our cross-border practice, the matrimonial vector produces claims that are less predictable in timing and highly fact-specific in their legal analysis. A trust structure that has been designed with the matrimonial question in mind – including the degree of the principal's retained control and the documentation of distribution decisions – is materially better positioned than one designed for succession or tax purposes alone.

The threshold question is not whether a principal needs a structure. For most principals with material Mainland exposure, that question is already answered by the facts. The question is whether the structure in place is adequate for the current legal environment – and whether it was designed to answer the right questions.

The sequence of steps matters. The bridge between the current position and the one you need is narrower after a dispute has arisen. The legal environment changed on 29 January 2024. Structures that were designed before that date against a different enforcement position should be reviewed now.

Decision matrix: structural choices across the principal risk categories

The choice of instrument and route depends on the principal's specific risk category. The following read-across is based on the verified legal mechanisms available in the current environment.

For a principal whose primary exposure is enforcement risk from Mainland commercial litigation: the priority instrument is a Hong Kong-law trust established before the dispute arises, holding assets that are legally situated in Hong Kong. The mechanism under Cap. 645 applies to civil and commercial judgments; a trust that genuinely separates the principal from the asset is better positioned than a company directly owned by the principal. The timing risk is avoidance-of-transaction exposure if the settlement occurs after a claim is known.

For a principal whose primary exposure is succession across both systems: the priority instruments are a Hong Kong-law trust governing the Hong Kong and offshore assets, a valid Mainland will governing the Mainland assets, and a Hong Kong will as a backstop for Hong Kong-situated assets not held in trust. The forced-heirship firewall in the reformed Trustee Ordinance is most effective where the trust is the governing instrument for the Hong Kong-situated assets. A will alone, wherever made, does not provide the same protection.

For a principal whose primary exposure is matrimonial: the priority instrument is a trust with a genuinely independent trustee and minimal retained powers. The degree of control retained by the principal is the central analytical question in any matrimonial court review of trust assets. Documentation of trustee decision-making, distribution history, and the rationale for distributions is as important as the trust deed itself.

For a principal facing multiple categories simultaneously – which is the common position – the structure requires integration across all three risk vectors. A trust designed for succession purposes but not for enforcement or matrimonial purposes leaves gaps. A structure designed for enforcement purposes but not for succession leaves the next generation exposed.
