Reading the risk in a reserved-powers trust

A founder who has spent decades building a business rarely wants to hand it over. Not to a trustee. Not yet. The instinct to retain control is understandable – commercially and personally. The question our desk faces repeatedly is whether a structure designed to give the founder everything also gives the trust nothing that matters legally.

A reserved-powers trust (a trust in which the settlor retains specified powers over investment decisions, distributions or even the removal of trustees) is a legitimate and widely used private-wealth instrument. Under the Trustee Ordinance (Cap. 29) as reformed with effect from 1 December 2013, Hong Kong law expressly confirms that a trust is not invalidated by the settlor reserving certain powers. The question is not whether the structure is valid. The question is whether the risk has been read accurately.

This analysis maps the commercial stakes, the governing instruments, the cross-border pressure points, and our read of where the real risk sits for a founder-controlled business using Hong Kong as the structuring hub.

What is actually at stake for the founder?

The reserved-powers trust is not primarily a tax instrument. For most founders bringing assets through Hong Kong, it is a control-and-succession device. The founder wants the business to continue on terms the founder sets, the family to benefit in proportions the founder chooses, and the whole arrangement to survive the founder's death or incapacity without triggering a forced sale or a governance crisis.

That is a coherent objective. It becomes commercially risky when the founder's retained powers are so extensive that the trust fabric frays under scrutiny – from a court, a tax authority, or a creditor. When the business sits beneath a BVI or Cayman holding entity, and the family is spread across Mainland China, Hong Kong, and a second-generation cohort resident in Europe or the United Kingdom, the scrutiny comes from multiple directions simultaneously.

Three commercial stakes dominate in our cross-border practice. First, governance continuity: can the trustee operate the business interest without the founder once the founder is gone? Second, succession certainty: is the intended distribution to the next generation enforceable against a forced-heirship claim arising in another jurisdiction? Third, creditor protection: does the trust actually separate the business assets from the founder's personal balance sheet, or does it merely move them one step further away?

The answers to all three questions depend heavily on how the reserved powers are drafted – and on which legal system is adjudicating the question. That is the interface this analysis examines.

What does the governing framework actually say?

The Trustee Ordinance (Cap. 29), as substantially reformed with effect from 1 December 2013, provides the foundational Hong Kong position. The reform settled three points that were previously uncertain at common law: a trust is not void or voidable merely because the settlor has reserved powers; the reserved powers may include powers over investment, appointment of trustees, and distribution; and a Hong Kong trust benefits from strengthened protection against foreign forced-heirship claims, meaning a court applying Hong Kong trust law will generally resist a challenge from a family member asserting a forced share under a foreign civil-law system.

These are meaningful protections. They are not absolute ones.

The reform did not change the sham-trust analysis. If the reserved powers are so extensive that a court – whether in Hong Kong, in the Mainland, or in the family member's country of residence – concludes that the trustee has no real discretion and the founder remains the beneficial owner, the trust character of the arrangement collapses. The assets fall back into the founder's estate. Forced-heirship claimants, creditors, and revenue authorities all move up the queue.

The distinction in practice turns on substance. Reserved powers over the removal of trustees and the appointment of successors are generally acceptable. Reserved powers that allow the founder to direct every investment decision and override every distribution in fact, not merely in theory, take the structure to the edge. Where the founder is also the de facto controller of the underlying business – as is common in a founder-controlled group – the substance test is applied with particular care by courts that know the pattern.

The governing instrument in Hong Kong is the Trustee Ordinance. The governing analytical tool is the body of common-law authority on sham transactions and beneficial ownership – a tradition Hong Kong shares with England and with the principal offshore common-law jurisdictions.

How does the cross-border interface bite?

A trust governed by Hong Kong law and administered by a Hong Kong trustee does not exist in isolation. The founder's family map determines which other legal systems can assert a claim on the assets.

Consider the typical pattern we see. The founder is a Mainland-Chinese national who has been resident in Hong Kong for some years. The operating business sits in the Mainland, beneath a BVI holding entity that is itself held by a Cayman company. The trust holds the shares of the Cayman company. The founder's spouse and adult children include one resident in Hong Kong, one in the United Kingdom, and one who has returned to the Mainland.

That single family map engages at least five legal systems: Hong Kong (trust law, residence, cross-border enforcement); the People's Republic of China (succession law, property law, potential forced-heirship analogues, business licensing); the BVI and the Cayman Islands (holding-entity law, economic-substance regimes); and the United Kingdom (residence-based succession and tax implications). The trust governs the Cayman holding shares. It does not govern the operating business in the Mainland. The gap between those two levels is where the real risk accumulates.

The Mainland succession position is the sharpest pressure point. The PRC does not have a forced-heirship regime in the precise civil-law sense, but PRC succession law protects certain classes of heir, and a family member with standing to claim before a Mainland people's court may seek to characterise the trust assets as part of the founder's estate if the sham-trust argument has traction in that forum. The Hong Kong trust law firewall protects the trust against foreign forced-heirship claims in Hong Kong proceedings. It has no direct effect on what a Mainland court does in Mainland proceedings over Mainland assets.

The Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance (Cap. 645), in force since 29 January 2024, has improved mutual recognition between Hong Kong and the Mainland courts on civil and commercial matters. Succession and matrimonial matters are excluded from its scope. That exclusion matters: a succession dispute over trust assets that is characterised differently in Hong Kong and in the Mainland may not benefit from the new enforcement mechanism. The family must not assume that a Hong Kong trust deed resolves a Mainland succession contest.

For the BVI and Cayman holding entities, the economic-substance regimes in both jurisdictions require genuine activity at the holding level. Where the founder's reserved powers mean all material decisions are taken by the founder personally – whether sitting in Hong Kong, the Mainland, or elsewhere – the substance requirement at the offshore holding level may be in question. That is a separate regulatory exposure sitting beneath the trust structure itself.

The comparative read: common law confidence versus civil-law exposure

The common-law tradition – shared by Hong Kong, the BVI, and the Cayman Islands – treats the reserved-powers trust with relative comfort. The courts understand the instrument. The doctrine of sham is well-developed. The limits are legible.

Civil-law systems approach the same structure differently. Where a family member's residence or domicile in a civil-law jurisdiction gives that jurisdiction a connection to the estate, the trust may be re-characterised as a fideicommissum, a usufruct, or simply as a nominee arrangement. The re-characterisation changes the succession and tax analysis in ways that Hong Kong trust law cannot prevent.

This is not a theoretical concern. In our cross-border practice, we regularly see situations where a trust structure that has been carefully crafted under Hong Kong or offshore law encounters a civil-law challenge in the country where the next generation has settled. The challenge rarely attacks the trust deed directly. It attacks the assets – arguing that they were never genuinely transferred out of the founder's estate, that the reserved powers make the transfer illusory, and that local succession or matrimonial rights therefore apply.

The practical lesson is that the choice of governing law for the trust is necessary but not sufficient. A Hong Kong trust with full firewall protection is still vulnerable to attack in a foreign jurisdiction over assets that are situated or deemed to be situated in that jurisdiction. The BVI and Cayman holding entities interpose a layer, but that layer depends on those entities being genuine entities – with their own governance, their own records, and their own decision-making process – rather than pass-through vehicles for the founder's instructions.

Where a founder insists on retaining reserved powers that are operationally equivalent to outright ownership, the cross-border risk does not disappear. It concentrates at the point where the structure meets a foreign court or a foreign revenue authority that is entitled – on its own analysis of substance – to look through the holding chain.

How does the reserved-powers analysis intersect with tax residence and substance?

Hong Kong taxes on a territorial basis: profits tax applies to Hong Kong-sourced profits only, at 8.25% on the first HK$2,000,000 of assessable profits and 16.5% above that threshold. There is no capital gains tax and no withholding tax on dividends in the general position. That regime makes Hong Kong an attractive administration hub.

But the trust structure sits above the Hong Kong operating or holding layer, and the tax question for the trust itself is governed by the rules of each jurisdiction in which the trustee, the settlor, or the beneficiaries are resident. A founder resident in Hong Kong, with a trustee also in Hong Kong, and beneficiaries spread across multiple jurisdictions, faces a tax-residency analysis in each of those jurisdictions separately. The foreign-sourced income exemption (FSIE) regime, in force from 1 January 2023 as amended, conditions the exemption of certain passive income items on economic-substance requirements. Where the trust holds an offshore entity that receives passive income, the FSIE analysis applies to that entity's position in Hong Kong.

For groups within scope of the Hong Kong minimum top-up tax and the Income Inclusion Rule under the Pillar Two framework – effective for fiscal years beginning on or after 1 January 2025 for in-scope multinational enterprise (MNE) groups with consolidated revenue of EUR 750 million or above – the holding structure above the operating group becomes part of a global effective-tax-rate calculation. A trust holding shares of a Cayman intermediate holding company that sits above a Mainland operating group may be within the perimeter of that calculation. The interaction between the trust layer and the Pillar Two computation is a structuring question that should be addressed before, not after, the trust is settled.

The reserved-powers analysis intersects with the substance question directly. If the founder's reserved powers mean that all investment and governance decisions are taken by the founder in Hong Kong, the management and control of the trust assets may be treated as being in Hong Kong for tax purposes – which may or may not be the intended outcome, depending on the founder's overall residence and filing position. Founders should not assume that a trust layer automatically changes the residence or source analysis for the underlying assets.

What foreign counsel – and founders – regularly get wrong

The first common error is treating the reserved-powers trust as a settled solution rather than an ongoing one. The trust deed is a document, not a result. The result depends on how the trust is administered over time – whether trustee decisions are genuinely the trustee's decisions, whether trustee minutes reflect real deliberation, whether the founder in practice defers to the trustee's judgment or simply issues instructions that are routinely followed.

Our desk regularly sees trusts that were validly structured at inception but have drifted into a pattern of administration that would not survive a contested sham-trust challenge. The reserved powers were within acceptable limits when the deed was signed. The pattern of conduct over five or ten years since then has moved the substance well beyond those limits. A challenge arising on the founder's death or incapacity – when the founder is no longer available to explain the arrangements – encounters a documentary record that tells the wrong story.

The second common error is treating the Hong Kong firewall as a global firewall. It is not. It is a protection against foreign forced-heirship claims in Hong Kong proceedings. A family member who pursues their claim in a Mainland people's court, or in an English probate proceeding, or in a French succession court, is not constrained by the Hong Kong Trustee Ordinance. Whether the trust is effective against that claim depends on the law applied by that court – and on whether that court treats the trust as a genuine transfer of assets or as a transparent nominee arrangement.

The third error is ignoring the interaction between the trust layer and the economic-substance requirements at the offshore holding level. A BVI or Cayman holding entity that has no genuine activity of its own – that exists to hold shares and follow instructions – is at risk under both the economic-substance regime of its home jurisdiction and the look-through analysis of any foreign tax authority that examines the holding chain.

The fourth error is failing to engage the cross-border succession analysis before the trust is settled. Once the deed is signed and the assets transferred, repairing structural problems is significantly more complex and potentially taxable. The time to map the forced-heirship exposure in the Mainland, the UK, and any other jurisdiction where family members are resident is before the trust is executed, not after a dispute has arisen.

The contextual bridge: where this matters now

The sequence above describes the standard analytical position. Your matter turns on the specific reserved powers in the draft deed, the jurisdictions the family actually occupies, and the current administrative pattern – which is where the risk is won or lost.

Where the risk actually sits now: the desk's read

Three risk clusters dominate our current analytical view.

The sham-trust risk is the most immediate. Reserved-powers trusts for founder-controlled businesses have been in use long enough that courts across common-law jurisdictions have built a detailed picture of the patterns that indicate genuine transfers versus transparent arrangements. The pattern recognition is sharpest where the founder is also the de facto manager of the underlying business, where trustee minutes are thin or formulaic, and where the founder's correspondence with the trustee reads as a series of instructions rather than a dialogue between independent parties. Founders who are building or are about to settle a structure in this category should assume scrutiny, not assume safety.

The succession-boundary risk is the most structurally complex. The Hong Kong reforms of 2013 were a genuine improvement. They gave Hong Kong trust law one of the more explicit forced-heirship firewalls in the common-law world. But that firewall has never been tested in a fully contested cross-border succession where a Mainland family member simultaneously pursues claims in Mainland and Hong Kong proceedings, engaging Cap. 645's new mutual-recognition mechanism on a matter that sits at the boundary between commercial and succession characterisation. That boundary is untested. Founders whose family maps include Mainland-resident heirs should not assume it is secure.

The regulatory-substance risk is the most systemic. Economic-substance requirements in the BVI and Cayman, the FSIE regime in Hong Kong, and – for large groups – the Pillar Two computation have collectively raised the cost of holding structures that lack genuine activity. A reserved-powers trust that sits above a chain of pass-through entities, each receiving instructions from the founder, is at risk under each of those regimes independently. The aggregate regulatory exposure is greater than the sum of its parts.

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

A micro-scenario: the BVI holding layer under challenge

A Hong Kong-resident founder of an Asian manufacturing group settled a Hong Kong-law reserved-powers trust in the years following the 2013 reform, holding BVI shares above a Mainland operating group. The reserved powers included a power to direct investments and to veto distributions. The trustee was a professional trustee based in Hong Kong.

The founder's adult child, resident in the United Kingdom, challenged the trust on the founder's death on two bases: first, that the trust was a sham because the reserved powers were indistinguishable from continued ownership; and second, that English residence gave English succession law a connection to the UK-situated assets (shares in a UK-incorporated subsidiary).

The matter required a coordinated response across Hong Kong and English proceedings. In Hong Kong, the trust was defended on the Trustee Ordinance firewall and the substantive administration record. The UK-situated asset position required separate analysis under English law applicable in the English proceedings. The outcome, qualitatively, depended on the quality of the trustee's historical records and the degree to which the reserved powers had been genuinely distinguished from day-to-day business control in practice. The matter resolved without a final judicial determination, but the cost – in professional fees, delay, and family disruption – was substantial. The lesson was structural: the UK-situated assets should have been reviewed before the trust was settled, and the trustee's administration records should have been built with contestability in mind from the outset.

Decision matrix: reading your own risk profile

A founder with reserved powers limited to trustee removal and successor appointment, a professional trustee with genuine discretion, a family concentrated in Hong Kong and the BVI, and no Mainland-resident heirs: the sham-trust risk is manageable; the succession risk is low; the regulatory-substance risk depends on the BVI entity's own activity record. This is the lower-risk profile.

A founder with reserved powers extending to investment direction and distribution override, an administrative pattern in which the trustee routinely implements the founder's instructions, a family map including Mainland-resident and UK-resident heirs, and a Pillar Two-sized operating group beneath the structure: the sham-trust risk is material; the succession-boundary risk is untested and therefore unquantifiable; the regulatory-substance risk is layered across multiple regimes simultaneously. This is the higher-risk profile, and it is not uncommon.

A founder who is uncertain which profile applies – because the structure was settled some years ago and has been administered without regular legal review – is, in our experience, more often in the higher-risk band than the lower one. The reason is simple: reserved powers that begin within acceptable limits tend to expand in practice as the founder's involvement in the underlying business deepens, and administrative shortcuts accumulate.

The diagnostic question is not "does the deed permit this?" The question is "does the pattern of conduct over the past five years support the legal character the deed was meant to create?" Those two questions have different answers more often than founders expect.

Frequently asked questions

What does the route look like for a reserved-powers trust for a founder-controlled business?

The route depends on the reserved powers actually drafted, the family's jurisdiction map, and the administrative pattern since the trust was settled. At its simplest, the process involves reviewing the deed against the substantive administration record, mapping the succession exposure in each jurisdiction where family members are resident, confirming the economic-substance position at the BVI or Cayman holding level, and then either affirming the structure or implementing targeted adjustments. Where a cross-border succession dispute has already arisen, the sequencing of Hong Kong and foreign proceedings – and the interaction with the mutual-enforcement regime under Cap. 645 – becomes the dominant strategic question. Parties should verify the current position before acting.

Do I need a Hong Kong adviser for a reserved-powers trust for a founder-controlled business?

Where the trust is governed by Hong Kong law, where the trustee is based in Hong Kong, or where the holding structure runs through a Hong Kong entity, a Hong Kong international counsel is a necessary part of the advisory team. The Trustee Ordinance (Cap. 29), the firewall provisions as reformed in 2013, and the cross-border enforcement position under Cap. 645 are Hong Kong instruments. For matters of Hong Kong law specifically, we work alongside locally licensed Hong Kong firms. In our cross-border practice, we regularly advise on the international dimension of structures of this kind, coordinating across the Hong Kong, BVI, Cayman, and client-origin jurisdictions.

Which jurisdiction's law applies to a reserved-powers trust for a founder-controlled business?

The trust deed should specify its governing law; if it specifies Hong Kong law, the Trustee Ordinance applies to the validity and administration of the trust, including the reserved-powers provisions and the forced-heirship firewall. However, the governing law of the trust does not control the succession law that a foreign court applies to assets situated in its jurisdiction or to heirs domiciled there. A Hong Kong-law trust with BVI-held shares, a Mainland operating group, and beneficiaries resident in the United Kingdom is subject to Hong Kong law on the trust itself – and to Mainland, BVI, and English law respectively on specific asset and succession questions arising in those jurisdictions.
