Matter note: succession planning across Hong Kong UK

Succession planning across two common-law systems – Hong Kong and the United Kingdom – is technically tractable, but the family's map of assets, residences and beneficiary locations determines which instruments govern and in which sequence they must be executed. The governing statutes in this matter were the Trustee Ordinance (Cap. 29) on the Hong Kong side and the relevant UK succession and trust instruments on the UK side. The turning point was recognising that the family's apparent symmetry across two common-law regimes masked a material conflict at the intersection of UK domicile rules and Hong Kong trust firewall protections.

This matter note describes an anonymised cross-border succession instruction. No identifying details have been included. The jurisdictional pattern and the strategic sequence are transferable to principals managing private wealth across Hong Kong and the United Kingdom.

What was the situation, and why did it require cross-border counsel?

The family had built its principal operating business in Asia over two generations. The founding generation held Hong Kong permanent residence. The second generation had relocated to the United Kingdom and acquired UK domicile of choice. Significant liquid assets sat in a BVI holding entity above the Hong Kong operating group. Real property was held directly in both jurisdictions.

The family had existing wills – one executed in Hong Kong, one in the UK. They also held a discretionary trust settled under Hong Kong law several years earlier. None of these instruments had been reviewed since the second generation established UK domicile. The immediate trigger for the instruction was a proposed restructuring of the BVI entity, which surfaced a question the family's domestic advisers could not resolve: to what extent would a future UK grant of probate engage the Hong Kong discretionary trust, and could a UK domicile determination affect the trust's firewall protections?

That question sits precisely at the cross-border interface between two systems that share a common-law tradition but diverge sharply on the treatment of domicile, forced heirship and offshore trust protections. Identifying it required counsel working across both sides simultaneously.

In our cross-border practice, we regularly see instructions of this shape. A domestic adviser on each side has done competent work within their own system. The gap appears only at the interface – and it appears at the worst possible time, typically when a transaction or a death brings the two systems into contact.

What was the core legal issue?

The core issue was the interaction between UK domicile rules and the Hong Kong trust firewall under the reformed Trustee Ordinance. The 2013 reform to the Trustee Ordinance, which took effect on 1 December 2013, substantially strengthened the position of Hong Kong-law trusts against foreign forced-heirship claims and gave statutory protection to settlors who reserved certain powers without invalidating the trust. That protection, however, is not unconditional. Its effectiveness depends on several factors: the governing law of the trust, the proper characterisation of the assets settled, and the domicile status of the settlor at the point of settlement.

The second generation's UK domicile of choice introduced a risk that a UK court administering an estate could characterise certain trust assets as part of the UK estate for domicile-related purposes. The BVI holding entity added a further layer. Shares in a BVI company are sited at the place of incorporation for succession purposes in most common-law analysis, but that siting is not universally applied, and a UK court administering the estate of a UK-domiciled individual has tools to look through or behind holding structures where the beneficial interest is the real subject of the inquiry.

The forced-heirship dimension was secondary in this family's case – neither Hong Kong law nor English law operates a rigid forced-heirship regime, unlike many civil-law systems. But the family included beneficiaries in a civil-law jurisdiction, and the possibility that a future succession dispute could invoke that jurisdiction's rules was not zero. The Hong Kong firewall provision in the Trustee Ordinance was directly relevant to managing that residual risk.

How did the family's asset map shape the strategy?

Asset mapping is the first technical step in any cross-border succession instruction. The map in this matter revealed four distinct categories, each with a different succession treatment.

First, the Hong Kong operating business shares, held indirectly through the BVI entity. Second, Hong Kong real property, held in the names of individuals in the founding generation. Third, UK real property, held in the names of the second generation. Fourth, liquid assets held through the discretionary trust, which itself was the owner of record of the BVI entity shares.

Each category engaged a different instrument and a different sequence. The Hong Kong real property would pass under a Hong Kong grant of probate, governed by the will executed in Hong Kong, subject to the requirements of the conveyancing regime for completion of transfers. The UK real property would pass under a UK grant of probate, with its own formalities and timelines. The discretionary trust assets would not form part of either estate, provided the trust was properly constituted and the reservation-of-powers issue was resolved.

That last condition was the strategic pivot. If the trust was properly constituted and the firewall protections applied, the BVI entity and the liquid assets within the trust would pass according to the trust instrument, not through either probate process. The entire weight of the succession planning work therefore concentrated on confirming the trust's position and addressing any deficiencies before they became the subject of a dispute.

Counsel on our desk regularly maps this kind of asset structure before advising on instrument selection. The map shapes everything: which will governs which asset, whether the trust achieves its intended purpose, and where the enforcement risk sits if the plan is not executed in sequence.

What was the sequence, and where was the turning point?

The instruction proceeded in four stages, worked simultaneously across the two jurisdictions with allied counsel admitted in the UK.

Stage one was the trust review. We reviewed the Hong Kong discretionary trust deed against the requirements of the reformed Trustee Ordinance. The review identified that the trust had been settled at a time when the settlor held Hong Kong permanent residence and had not yet established UK domicile of choice. The governing law clause in the trust deed specified Hong Kong law. On that analysis, the firewall protections were engaged. The reservation-of-powers provisions in the deed were within the scope of the statutory protection introduced by the 2013 reform. No amendment to the trust deed was required.

Stage two was the domicile analysis. This is the turning point. Working with allied UK counsel, we examined the second generation's position on UK domicile of choice. Domicile of choice is acquired by residence with the intention to reside permanently or indefinitely. The evidence in this case was clear: the second generation had established UK domicile of choice. That determination had two consequences. It meant that UK succession law governed their worldwide movable estate on death, absent a valid choice of law in any applicable instrument. It also meant that the interaction between the UK estate and the Hong Kong trust required express documentation to confirm the trust's position as outside the estate.

Stage three was the will review and re-execution. The existing Hong Kong will was adequate in form but had not been updated to reflect the trust's current structure. The existing UK will made no express provision regarding the trust or the BVI entity. Both wills were revised. The revised Hong Kong will dealt expressly with the Hong Kong immovable property and included a recital confirming the trust's separate position. The revised UK will addressed the UK immovable property and movable assets properly within the UK estate, and included an express exclusion of the trust assets from the UK estate on the basis of the trust structure.

Stage four was the BVI structuring review. Allied counsel in the BVI confirmed that the BVI entity's register of members was held with the registered agent in the BVI, and that the shares were therefore sited in the BVI for succession purposes under the governing analysis. That siting placed those shares within the trust, not within either individual estate, and the confirmation was documented in a memorandum to the family's file.

The turning point in the instruction – the moment at which the risk was resolved rather than merely identified – was the decision in stage two to treat the domicile question as a preliminary matter rather than an assumption. Several prior advisers had assumed the second generation held UK domicile and had not documented the consequences for the Hong Kong trust. That undocumented assumption was the gap. Bringing it into the open and documenting the analysis removed the enforcement risk.

What was the outcome, and what is the transferable lesson?

The qualitative outcome was a succession plan that aligned the governing instruments in both jurisdictions with the family's asset map and the trust structure. The trust's firewall protections were confirmed as operative. Both wills were updated and properly executed. The BVI siting analysis was documented. The family's advisers in both jurisdictions held a complete and coordinated file.

No litigation arose from this instruction. That is the intended outcome of succession planning done in advance of a triggering event. The risk that was resolved – a UK domicile-based challenge to the trust assets – would have been expensive and disruptive to contest after a death. Resolving it during the planning phase cost a fraction of what contested litigation would have involved.

The transferable lesson is this: two common-law systems do not automatically produce a compatible succession plan. The shared tradition creates a degree of mutual recognition and analytical familiarity, but the rules on domicile, trust firewall protections and the siting of assets diverge in ways that matter. When a family has material assets and residences in both Hong Kong and the United Kingdom, the succession plan must be built from the asset map outward, engaging counsel who can read both sides simultaneously rather than working from each side independently.

A second lesson concerns timing. The instruction was triggered by a corporate restructuring, not by a death. That is the optimal moment. By the time a death occurs, the options narrow sharply. The documents govern whatever they say, the domicile analysis is fixed, and the litigation risk is real. Families who review their cross-border succession plan before a transaction or a change in residence retain the widest set of options.

Our private wealth practice handles instructions of this kind regularly, coordinating the Hong Kong and offshore dimensions and working alongside allied counsel in the relevant jurisdictions. The approach is the same in each case: map the assets, identify the governing instruments, locate the gaps, and close them before the triggering event arrives.

For principals managing assets across Hong Kong and the United Kingdom, two related matters may also be relevant: our briefing on reserved powers trusts and founder-controlled businesses addresses the settlor-powers question in depth, and our note on asset protection for principals with CIS exposure covers the enforcement dimension where additional jurisdictions are engaged.

If a prior succession plan has not been reviewed since a change in residence or a material change in the asset map, the risk profile has changed. A structured review across both sides is the appropriate response.

Frequently asked questions

What documents are needed for succession planning across Hong Kong and the United Kingdom?

The core documents are a Hong Kong will dealing with Hong Kong-sited assets, a UK will dealing with UK-sited assets and worldwide movables for a UK-domiciled individual, and – where a trust exists – a review of the trust deed against the requirements of the Trustee Ordinance (Cap. 29) on the Hong Kong side. Where a BVI or Cayman holding entity is involved, the register of members and the constitutional documents of the entity are also required. The precise document set depends on the family's asset map, domicile position and the jurisdictions in which assets are held. A coordinated review across both sides is the starting point.

What is the first step in succession planning across Hong Kong and the United Kingdom?

The first step is an asset map that identifies each category of asset, its jurisdiction of siting, the name in which it is held, and the instrument currently governing its succession. That map determines which wills, trusts and holding structures are engaged, and where the gaps sit. In our cross-border practice, the asset map almost always reveals assumptions that have not been documented – typically around domicile or around the interaction between a trust and one of the estates. The map must precede any drafting or restructuring work.

How does the cross-border element affect succession planning across Hong Kong and the United Kingdom?

The cross-border element affects succession planning in three principal ways. First, the governing law of the estate – which depends on domicile for movables and on siting for immovables – may differ between Hong Kong and the UK, producing different legal requirements for each asset category. Second, a trust settled under Hong Kong law benefits from the firewall protections in the reformed Trustee Ordinance, but the effectiveness of those protections depends on the settlor's domicile at settlement and the trust's governing law. Third, holding structures interposed between the individual and the assets – BVI entities, Cayman vehicles – have their own succession and siting implications that must be addressed in coordination with both the Hong Kong and UK instruments.
