Matter note: a single-family office structured through Hong Kong

A single-family office structured through Hong Kong can consolidate asset governance, succession planning and cross-border enforcement under one jurisdiction – but only when the holding structure, the trust instrument and the principal's residence position are aligned from the outset. This matter note describes how one principal family achieved that alignment, working through a sequence that placed the Trustee Ordinance (Cap. 29) at its centre and Hong Kong as the governing forum. The note is anonymised: no client-identifying facts, no named parties, no disclosed sums.

The matter reached us in the second half of a calendar year. A principal family with operating businesses across two Asian jurisdictions and investment assets in Europe had reached a point where the informal holding arrangements built over a decade were no longer adequate. A generational transfer was visible on the horizon. The existing structure offered no succession mechanism, no forced-heirship firewall and no clear answer on which law governed the assets at the moment of transfer. The window was open – but not indefinitely.

What was the situation and what constraint did the family face?

The family's wealth sat across three tiers: operating entities in the Mainland and in Southeast Asia, a BVI holding layer above them, and European portfolio assets held in personal name. The principal was resident outside Hong Kong. One adult child lived in a civil-law jurisdiction with a mandatory forced-heirship regime. A second was in a common-law jurisdiction with no such rule. A third was a minor.

The constraint was structural and urgent at the same time. The civil-law jurisdiction where the first adult child was resident applied its forced-heirship rules to moveable assets wherever they were held if the deceased was habitually resident there – or, under certain conflict-of-laws analyses, if the beneficiary was. That analysis had not been resolved. In our cross-border practice, we see this pattern regularly: a family that has organised itself for growth has not organised itself for transfer, and the jurisdictional exposures that were dormant during the accumulation phase become material when succession is in sight.

A second constraint was governance. The family had no documented investment policy, no formal decision-making authority and no mechanism for managing disputes among the next generation. Those gaps matter not only internally but at the point of enforcement: a creditor or a claimant in any of the relevant jurisdictions could challenge an informal arrangement far more easily than a properly constituted trust with clear terms.

What was the core legal issue and why did Hong Kong become the chosen forum?

The core legal issue was the intersection of three things: the forced-heirship exposure in the civil-law jurisdiction, the absence of a succession vehicle that could hold the BVI layer and the European assets, and the need for a forum whose law offered a tested forced-heirship firewall while preserving the principal's ability to retain meaningful oversight during his or her lifetime.

Hong Kong answered all three. The Trustee Ordinance, substantially reformed with effect from 1 December 2013, removed the rule against perpetuities for Hong Kong trusts and introduced statutory protection for trusts where a settlor reserves certain powers – meaning the principal's wish to retain involvement did not invalidate the structure. Crucially, the 2013 reform also strengthened Hong Kong's firewall against foreign forced-heirship claims. A trust governed by Hong Kong law is not set aside merely because the law of another jurisdiction would distribute the assets differently on death.

Hong Kong's position as a common-law forum with English as an official working language of the courts also meant that the BVI holding layer – which was already governed by BVI law and administered under familiar common-law principles – sat naturally beneath it. The Court of First Instance of the High Court provided a credible enforcement venue if trust terms were ever disputed. Singapore was considered and offered comparable trust law. Hong Kong was chosen because the family's Greater China operating assets made a Hong Kong-governed holding trust the more coherent centre of gravity.

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.

How did the matter actually run, and where was the turning point?

The matter ran in four phases. The first was a jurisdictional mapping exercise. Before any structure was committed to paper, the family's existing assets and the beneficiaries' residence positions were mapped against the conflict-of-laws rules of each jurisdiction in play. That meant identifying which assets were moveable and which were immoveable, which jurisdictions asserted jurisdiction on the basis of the asset's situs, and which applied the law of the principal's habitual residence.

The mapping produced a clear picture. The European portfolio assets – held in personal name – were the most exposed. The BVI holding layer was insulated from the forced-heirship jurisdiction's direct reach, but the shares in the BVI entities could themselves be characterised as moveables with a situs in a jurisdiction that would not give effect to the firewall unless the trust was properly constituted under Hong Kong law with the right governing-law clause.

The second phase was the trust structure itself. A discretionary trust governed by Hong Kong law was settled, with the BVI holding entities placed beneath it. The instrument contained a governing-law clause, a trustee-power clause that accommodated the principal's reserved powers within the statutory framework, and a letter of wishes that addressed the different positions of the three children. The European portfolio assets were transferred into the trust structure via an assignment that recognised the situs rules of the European jurisdiction.

The turning point came in the third phase, during negotiation of the letter of wishes. The first adult child – the one resident in the civil-law forced-heirship jurisdiction – was not a beneficiary in name, but the principal's instructions gave that child a significant share of the income. Counsel on our desk identified that this arrangement, as initially drafted, risked being characterised in the civil-law jurisdiction as a sham or a disguised testamentary disposition, which would have undermined the firewall. The letter of wishes was restructured so that the trustee's discretion was genuine and the income allocation was clearly a matter of ongoing discretionary decision, not a fixed entitlement dressed as something else. That adjustment – not large on its face – was the hinge on which the enforcement position turned.

The fourth phase was governance. The family office entity – a Hong Kong company coordinating investment decisions for the trust – was established under the Companies Ordinance (Cap. 622). A Significant Controllers Register (the register of registrable persons required to be maintained by a Hong Kong-incorporated company under the Companies Ordinance) was properly maintained from incorporation. An investment policy statement and a family charter were prepared alongside the trust instrument. Neither is a legal document in the strict sense, but both are material to the trustee's ability to demonstrate that decisions are made on a proper basis if challenged.

What was the qualitative outcome and what does it transfer to other matters?

The immediate outcome was a structure in place before the principal's health position changed further. That timing mattered. Had the principal lost capacity before the trust was properly settled, the assets would have passed under the forced-heirship rules of the relevant jurisdiction by default, with no firewall available.

The substantive outcome was a holding structure in which the principal retained visible involvement during his or her lifetime – through the reserved powers mechanism under the Trustee Ordinance – while the succession position was fixed under Hong Kong law. The forced-heirship risk was managed at the point of trust settlement, not left to litigation after the event.

The transferable lesson is one of sequence. Many principals settle a trust and then address the conflict-of-laws analysis later, or delegate it entirely to the trustee. In a cross-border family with members in multiple jurisdictions, the conflict-of-laws mapping must come first. It determines not only the choice of governing law but the situs of the assets to be transferred, the characterisation of the interests created and the enforceability of the instrument in each jurisdiction where a claim might arise.

A second transferable lesson concerns the letter of wishes. A letter of wishes is not a legal document, but in a forced-heirship dispute it may be the first document a foreign court reads. If it is drafted to look like a binding allocation rather than a genuinely discretionary indication, it gives the claimant the characterisation argument they need. Precision in the document matters as much as precision in the trust deed itself.

We regularly act on cross-border private-wealth matters of this kind – involving a Hong Kong holding layer, an offshore trustee structure and beneficiaries in civil-law jurisdictions with competing succession regimes. The sequence described here is not a template; each family's map is different. But the analytical steps – situs, characterisation, firewall applicability, letter-of-wishes drafting – repeat across matters.

If an earlier structure, a stalled trust instrument or an adverse conflict-of-laws assessment has produced uncertainty, a second read can identify the steps still available and the route forward.

The cross-border interface: where Hong Kong law meets civil-law succession rules

Hong Kong has no forced-heirship regime. A settlor may distribute his or her estate freely under a Hong Kong-law trust without any portion being reserved for children, spouses or other relatives as a matter of right. That position, confirmed in the Trustee Ordinance, is the starting point of the firewall analysis.

The harder question is whether the firewall holds when a beneficiary or a claimant is resident in a jurisdiction that does apply forced heirship. The answer depends on conflict-of-laws rules in the claimant's jurisdiction, not in Hong Kong. Some civil-law systems apply their forced-heirship rules to all moveables wherever situated if the deceased was domiciled in that jurisdiction at death. Others apply them only to assets within their own territory. Others again use a habitual-residence test for the beneficiary.

The Hong Kong firewall – strengthened by the 2013 reform to the Trustee Ordinance – operates at the level of the trust itself: a trust governed by Hong Kong law is not invalidated by foreign forced-heirship claims under Hong Kong law. Whether a foreign court will give effect to that conclusion is a question for the foreign court, applying its own conflict-of-laws rules. That is why the situs mapping is critical. If the assets with the most value can be put into a structure whose situs is not within the reach of the civil-law jurisdiction's rules, the firewall works in practice and not just in theory.

In the matter described here, the European portfolio assets were the most difficult to insulate because their situs was within the reach of the relevant civil-law jurisdiction's rules on immoveable property. The solution was to transfer them into the trust while the principal had capacity and to ensure that the transfer itself was effective under the law of the situs. Doing that work during the principal's lifetime, with capacity confirmed, removed the testamentary-disposition argument that would otherwise have been available.
