A practical guide to asset protection for a principal with Mainland China exposure

The question arrives quietly. A principal whose business is in the Mainland, whose family sits across two or three passports, and whose assets span Hong Kong, an offshore holding company and a property portfolio faces a risk that is easy to ignore until it is no longer avoidable: what happens to all of this when circumstances change? A regulatory inquiry, a commercial dispute, a divorce, a death, or simply the first serious succession conversation can reveal a structure that was never designed for protection at all.

Asset protection for a principal with Mainland China exposure requires a deliberate sequencing of structure, residence and succession documents across at least two legal systems – typically Hong Kong and an offshore trust jurisdiction – governed by instruments including the Trustee Ordinance (Cap. 29) and the relevant trust law of the chosen offshore centre. The cross-border interface between Mainland China and Hong Kong is the point at which most unplanned exposures become visible, and the point at which a well-sequenced structure first demonstrates its value. Since the Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance (Cap. 645) came into force on 29 January 2024, the enforcement corridor between the two systems has widened considerably.

This guide sets out the decision the principal faces, the sequence of steps in order, the common mistake that appears at each gate, and a short checklist for assessing readiness. It addresses the Mainland–Hong Kong cross-border interface throughout.

Why does Mainland China exposure change the asset protection calculus?

A principal with purely offshore or purely Hong Kong assets faces a well-mapped set of risks. Add Mainland China exposure and the position changes. The Mainland legal system is a civil-law system; Hong Kong is a common-law system. The two coexist within the one country, two systems framework, but their enforcement mechanisms, property-rights regimes and succession rules operate differently. A structure designed only for one side of the boundary may perform poorly on the other.

The enforcement corridor matters in both directions. A Mainland court judgment can now be registered in the Court of First Instance in Hong Kong under Cap. 645, once it is effective and falls within the scope of the Ordinance. The old requirement for an exclusive jurisdiction clause in the underlying contract has been removed; a connection-based test now applies instead. This means that a creditor with a Mainland judgment against a principal has a more direct route to Hong Kong-situated assets than was previously available.

Succession is equally asymmetric. The Mainland applies its own civil-code succession rules, including forced-heirship provisions protecting certain statutory heirs. Hong Kong law has no forced-heirship regime. An offshore trust governed by Hong Kong law benefits from the firewall and anti-forced-heirship provisions strengthened by the 2013 reform of the Trustee Ordinance, which also abolished the rule against perpetuities for Hong Kong trusts with effect from 1 December 2013. A principal whose assets sit on the Mainland side of the boundary, without an offshore structure above them, has no equivalent protection.

In our cross-border practice, the principals who come to us earliest in this process tend to have a cleaner set of options. Those who arrive after a dispute has been issued, or after a family event has crystallised, are working with a reduced menu.

Step one: map the family's asset and residence picture before deciding anything

The first gate in the sequence is information, not structure. No protective arrangement can be calibrated without a clear view of where the assets sit, who holds them, and what legal systems currently govern each category. This step is not legal work in the narrow sense; it is diagnostic work that precedes legal work. Skipping it produces a structure that addresses the wrong exposures.

The map should cover five dimensions. First, asset location: Mainland real property, operating company equity, Hong Kong property, offshore holding vehicles, listed and unlisted securities, and liquid assets. Second, current legal ownership: personal name, corporate name, jointly held, or already in a trust or fund structure. Third, the family's residence and domicile picture, including the citizenship and habitual-residence status of the principal, the spouse, and any adult children who may be heirs. Fourth, existing succession documents: wills made under which governing law, and whether any offshore trust already exists. Fifth, existing contingent liabilities: commercial guarantees, undisclosed pledges, tax positions.

The cross-border angle is particularly acute for Mainland operating companies. Equity in a wholly foreign-owned enterprise (WFOE, an onshore Mainland company established by a foreign investor) held directly by the principal is an asset inside the Mainland legal system. It cannot be moved into an offshore trust without a restructuring that involves Mainland regulatory clearance. That restructuring takes time and has conditions. If the principal waits until a threat materialises, the window for a clean restructuring may have closed.

Step two: assess the governing law of each asset class and its interaction with protection instruments

Each category of asset carries its own governing law, and that governing law determines what protection instruments are available. This step is where the cross-border legal analysis begins in earnest.

Mainland real property is subject to Mainland law. An offshore trust cannot directly own Mainland land; the chain of ownership must pass through an onshore Mainland entity or a permitted offshore-to-onshore structure, each of which has its own restrictions. The principal should understand which assets can be placed into a protective structure immediately, which require a regulatory approval step first, and which will remain exposed by design.

Hong Kong-situated assets – property, bank accounts, securities, shares in a Hong Kong company – are within the reach of a Hong Kong-law trust and benefit from the protections of the Trustee Ordinance. The 2013 reform is directly relevant: a trust is not invalidated under Hong Kong law by the settlor reserving certain powers, and a Hong Kong-law trust carries strong firewall protection against foreign forced-heirship claims. For a principal whose statutory heirs under Mainland law would otherwise have forced-heirship rights over Hong Kong assets, this firewall is material.

Offshore holding vehicles – a BVI business company (a company incorporated under the BVI Business Companies Act, the most common offshore holding form for Greater China structures) or a Cayman Islands vehicle – sit in yet another legal system. Their shares can be placed into a trust. But the trust must be properly constituted: the shares must be transferred to a trustee, the trust document must address the relevant risk categories, and the trustee must have genuine control. A structure where the principal retains de facto control of every decision is vulnerable to challenge, including challenge by a Mainland court that treats the trust as a sham.

The interaction between these three layers – Mainland assets, Hong Kong assets, offshore vehicles – is what makes cross-border asset protection structurally different from single-jurisdiction planning. Our desk sees structures regularly that address one layer well and leave the other two unattended.

Step three: choose the structural instruments and sequence the implementation

Once the asset and governing-law map is clear, the next gate is instrument selection. The two principal instruments in this space are the discretionary trust and the family holding company, used separately or in combination. Each has a distinct profile for the Mainland-exposed principal.

A discretionary trust (a trust in which the trustee has discretion over the distribution of income and capital among a defined class of beneficiaries) holds assets for the benefit of the family without giving any beneficiary a fixed legal entitlement. For succession purposes, this means that the trust assets do not form part of the principal's estate at death; they pass in accordance with the trust deed, not the applicable succession law. For asset-protection purposes, the principal no longer holds legal title; a creditor must attack the trust itself, not simply execute against the principal's assets.

A family holding company – typically a BVI or Cayman company above the operating structure – provides corporate separation but not the same succession or creditor protection. Shares in a holding company are an asset of the shareholder. They can be executed against, they form part of the estate at death, and they are subject to the shareholder's domestic succession law. Their value lies in structural efficiency and in providing a vehicle that can then be held by a trust, not in standalone protection.

The sequencing rule is this: establish the trust first, then restructure the holding company chain to place the vehicle under the trust. Restructuring in the other order – cleaning up the holding company chain first, then establishing the trust – can create a window during which the assets are exposed to any claim that arises. A principal who is in the middle of a commercial dispute when the restructuring is incomplete may find that the intermediate state is worse than the starting state.

The Mainland restructuring, where onshore equity is involved, runs in parallel with the offshore trust work but on a separate regulatory track. Mainland regulatory approval – under the rules governing outbound direct investment and cross-border capital transfers – is required before offshore structures can own Mainland equity. This approval process involves the principal's operating entity, the relevant approving authority, and a set of disclosures. It is not quick. Principals who begin this process under time pressure from a dispute or a succession event are at a material disadvantage.

For detailed analysis of how the trust element functions within a broader family-office structure, our analysis of single-family offices structured through Hong Kong addresses the interaction between holding structure, governance and succession instruments in the Greater China context.

Step four: address the succession layer explicitly

Asset protection and succession planning are not the same exercise. Many principals complete a trust structure and assume the succession question is answered. It is not. The succession layer requires its own instruments, and for a principal with Mainland exposure it requires instruments that engage two or more legal systems deliberately.

A will is the starting point but not the finishing point. A principal with assets in the Mainland, in Hong Kong, and in an offshore centre may need separate wills – or a will with territorial schedules – to address each category cleanly. A single will drafted under one jurisdiction's law may not be recognised in another, may be subject to different formality requirements, and may be overridden by local forced-heirship rules in the jurisdictions where it is not the governing instrument.

The Mainland succession position is governed by the Civil Code succession rules. Certain statutory heirs – including a surviving spouse, children, and parents – hold protected positions. Those rights apply to Mainland-situated assets. They do not disappear because an offshore trust has been established over Hong Kong or offshore assets. The firewall in the Trustee Ordinance protects the Hong Kong-law trust from foreign forced-heirship claims over trust assets. It does not change the position for Mainland assets, which remain subject to Mainland law.

This asymmetry is the practical core of the cross-border succession problem. The correct approach is to acknowledge which assets will be subject to forced-heirship claims and plan the distribution of those assets within the Mainland succession framework, while using the offshore trust to govern the assets that the firewall can protect. Trying to use the offshore trust to circumvent forced-heirship rights over Mainland assets is a strategy that tends to produce litigation rather than protection.

For a more detailed treatment of how a family business interest can be held through a trust structure across the Mainland–Hong Kong interface, see our guide to holding a family business interest through a trust.

The sequence for the succession layer runs alongside, not after, the structural work. Trust deed provisions on succession, the powers of any protector or advisory committee, and the letter of wishes should all be drafted with the family's succession intentions in mind, not as afterthoughts once the structure is set.

The contextual bridge here is practical: the succession layer is where the structure is tested most severely, because death and incapacity cannot be scheduled. A principal whose trust deed is silent on what happens if the protector and the principal become incapacitated simultaneously has a gap that will be exposed at the worst possible moment.

If an earlier structuring attempt left gaps in the succession layer, or produced a trust deed that does not engage the Mainland–Hong Kong interface directly, a second review can identify those gaps and the steps still available to address them.

Step five: build and maintain the substance and documentation record

A protective structure is only as strong as its documentation and its operational substance. This is the step most frequently completed inadequately. A trust that exists on paper but is administered as though the assets still belong to the principal personally is vulnerable to a sham trust challenge (a challenge by a creditor or a court that the trust is not a genuine transfer of beneficial ownership but a device to obscure the principal's continuing ownership).

The documentation record has three layers. The first is the constitutive documents: the trust deed, any protector deed, the letter of wishes, the corporate documents of any underlying holding vehicles, and the register of beneficial owners. The second is the operational record: trustee resolutions, distribution records, investment mandates, board minutes of the underlying companies, and evidence that the trustee is exercising genuine discretion. The third is the regulatory record: filings with the Companies Registry, the Significant Controllers Register (the register of beneficial owners that Hong Kong-incorporated companies have been required to maintain since 1 March 2018), and any equivalent offshore register.

Cross-border documentation is particularly important. A BVI holding company above a Hong Kong operating company above a Mainland WFOE generates regulatory filing obligations in all three jurisdictions. Gaps in any one layer can expose the whole chain. In our cross-border practice, we regularly see structures where the Hong Kong layer is well-documented and the BVI layer is maintained only at the minimum required by the BVI registry, with the result that the substance of the structure sits in an underdocumented vehicle that is difficult to defend under scrutiny.

The substance point applies to holding structures more broadly. For further context on how the holding layer functions and the substance requirements that apply to offshore vehicles above Hong Kong operating companies, see our overview of private wealth structuring through Hong Kong.

The common mistake: leaving the Mainland layer unaddressed

The most common error we see in structures built for Mainland-exposed principals is this: the offshore and Hong Kong layers are structured carefully; the Mainland layer is left in the principal's personal name, or in a corporate vehicle that is directly owned by the principal, on the basis that "the Mainland assets are a separate matter" to be addressed later.

They are not a separate matter. They are the layer most likely to be the subject of a claim, a regulatory inquiry or a succession dispute. And because Mainland restructurings require regulatory approval and take time, "later" frequently means "after the window has closed".

A related error is treating the trust as a fixed structure rather than a living instrument. A trust that was properly constituted ten years ago for a different family composition, a different asset mix, and a different enforcement environment may now have gaps. Cap. 645 changed the enforcement corridor between the Mainland and Hong Kong from 29 January 2024. A structure built before that date should be reviewed for any position that the new regime affects.

A third error is conflating asset protection with confidentiality. Beneficial ownership registers, reporting obligations, and mutual administrative assistance between tax authorities mean that the confidentiality case for offshore structures has diminished substantially. The protection case – genuine separation of legal title, clear succession, a trustee with substance – remains strong. But a structure designed primarily to conceal will not perform as a protection structure.

Decision checklist for the principal with Mainland China exposure

The following questions are addressed to the principal who wants to assess readiness before engaging counsel. A "no" or "unsure" answer at any point identifies a gap in the current position.

On the asset and residence map: Has each category of asset been mapped by jurisdiction, by current legal owner, and by governing succession law? Is the residence and domicile position of the principal and of each prospective heir clear?

On the Mainland layer: Does the structure above any Mainland operating company or Mainland property involve an offshore holding vehicle, or do those assets sit directly in the principal's personal name? If an offshore vehicle is in place, has the chain from the Mainland entity upward been approved under the applicable outbound-investment rules?

On the trust: Is a trust in place? If so, is it governed by a law with a meaningful forced-heirship firewall and the abolition of the rule against perpetuities? Is the trustee genuinely independent, or does the principal retain de facto control over every material decision? Is the trust deed current and consistent with the family's succession intentions as they stand today?

On the succession documents: Is there a will – or a set of wills – that addresses each category of assets in the jurisdictions where those assets are situated? Has the interaction between the will and the trust been reviewed by counsel who understands both instruments?

On documentation and substance: Are all three layers of the documentation record current? Has the structure been reviewed since Cap. 645 came into force?

On timing: Is any commercial dispute, regulatory inquiry or family event in prospect that would affect the window for restructuring? If the answer is yes, the sequence described in this guide becomes time-critical.

The sequence above describes the standard position for a principal building or reviewing an asset-protection structure with Mainland exposure. Your matter turns on the specific assets, the jurisdictions actually engaged, the family's succession intentions, and the order in which each step can realistically be taken. That is where the route is won or lost.
