Succession planning across Hong Kong and the United Kingdom

A family with property in London, a holding structure in Hong Kong and liquid assets split across two jurisdictions does not face one succession question. It faces at least four, running in parallel under two distinct legal systems. The point at which those questions collide – a death, an incapacity, a forced sale – is the worst moment to discover the gap.

Succession planning across Hong Kong and the United Kingdom requires a coordinated structure under both the Trustee Ordinance (Cap. 29) and the applicable English succession and trust law, with residence, domicile and the interaction of each system's approach to forced heirship mapped before any document is drafted. Hong Kong law has no forced-heirship regime and abolished the rule against perpetuities for Hong Kong trusts with effect from 1 December 2013; English law takes a materially different position on certain of those questions. The two systems must be addressed together, not sequentially.

This page sets out when a cross-border principal needs this engagement, the route we run and where locally licensed counsel join the process, the documents and decisions the client must own, and the critical structural choices the Hong Kong–UK interface demands.

When does a principal need succession planning across Hong Kong and the United Kingdom?

The trigger is almost always structural complexity rather than age or illness. A principal who holds a residential property in England or Scotland, directly or through a holding vehicle, and who also has a Hong Kong-connected operating or holding structure, has created a fact pattern that sits uneasily in either jurisdiction alone.

In our private-wealth practice, the four triggers we see most often are these. First, a family acquires UK real property and the title is held in a name that does not match the succession plan. Second, a Hong Kong or Mainland Chinese principal changes their UK residence status – whether by taking the British National (Overseas) route or securing indefinite leave to remain – and the change carries domicile implications that were not anticipated at the time. Third, the principal's home jurisdiction imposes a forced-heirship regime, and neither the Hong Kong holding structure nor the English will has been tested against that claim. Fourth, a death or incapacity occurs and reveals that assets in one jurisdiction are locked behind a process the other system cannot recognise or assist with.

Each of these triggers calls for the same diagnostic: a map of assets across both systems, a read of the domicile and residence position under English conflict-of-laws rules, an assessment of whether any forced-heirship claim from a third jurisdiction could reach assets held under either regime, and a document set that actually works on both sides of the engagement.

Structural complexity, not crisis, is the right moment to act. Once the document set is in place, the ongoing burden is modest. Before it is in place, any change in the family's residence or asset position reopens the exposure.

What is the governing position in each jurisdiction?

Hong Kong succession and trust law is built around the Trustee Ordinance (Cap. 29), the Wills Ordinance and the Intestates' Estates Ordinance. The 1 December 2013 reforms to the Trustee Ordinance removed the rule against perpetuities for Hong Kong trusts, protected a settlor's reserved powers against the trust being invalidated, and strengthened the firewall against foreign forced-heirship claims. A trust governed by Hong Kong law sits on a strong statutory base. It will not automatically import the forced-heirship rules of a civil-law jurisdiction that might otherwise claim a share of the estate.

English succession law operates on different foundations. England and Wales apply the principle of freedom of testamentary disposition, but the Inheritance (Provision for Family and Dependants) Act creates a class of claimants – surviving spouses, children, dependants – who may apply to the court for reasonable provision from the estate, even against an express testamentary instruction. Scotland has its own regime of legal rights, which cannot be defeated by will. These are not the same as civil-law forced heirship, but they are constraints that must be mapped against the family's specific composition.

Domicile is the central conflict-of-laws concept in this engagement. English law determines succession to moveable property by reference to the law of the deceased's domicile. Succession to immoveable property – English land, in most cases – is governed by English law as the lex situs (the law of the place where the property is situated). A principal who is domiciled in Hong Kong but holds English real property faces a split: English law governs the land; Hong Kong law (or the law of the domicile) governs the moveable estate. That split must be reflected in the document set.

For principals with assets or family connections in a civil-law jurisdiction – a Mainland Chinese family, a European holding structure, a Middle Eastern trust beneficiary – the interaction between that third system and both Hong Kong and England adds a further layer. The firewall provisions of the reformed Trustee Ordinance offer real protection, but they are not absolute, and the structure must be built to rely on them correctly.

How does the Hong Kong–UK interface actually work?

The fundamental tension in a Hong Kong–UK succession plan is this: the two systems share a common-law tradition, which means they recognise each other's instruments more readily than a civil-law jurisdiction would, but they are not unified, and an instrument drafted for one system will not automatically function in the other.

A Hong Kong will, drafted and executed under the Wills Ordinance, can in principle be admitted to probate in England if it meets the formal requirements under English conflict-of-laws rules. The Wills Act 1963 (England and Wales) provides a choice-of-law mechanism: a will is formally valid if it complies with the internal law of the place of execution, the domicile of the testator at the time of execution or death, or the place of the testator's habitual residence or nationality. In practice, a principal who moves between Hong Kong and the UK will often benefit from separate wills for each jurisdiction, executed to the formal requirements of each, with a carefully drafted non-revocation clause to prevent the later will from inadvertently revoking the earlier one.

Trusts create a different question. A Hong Kong-law discretionary trust holding moveable assets will generally be recognised in England and Wales under the Hague Convention on the Law Applicable to Trusts and on their Recognition, to which the UK is a signatory. That recognition is not, however, a guarantee that the trust assets are insulated from all English-law claims. A claim under the Inheritance Act or a matrimonial claim on divorce engages different rules, and the trust structure must be tested against those specifically.

English real property adds a further layer. Land held in England cannot be held in trust in the same manner as moveable assets under some offshore structures. A holding company registered in England, a bare trust, or a direct title are the more common routes. Each carries different stamp duty land tax, inheritance tax and succession consequences. The choice of holding vehicle for UK real property is a decision that sits at the intersection of English tax law and the succession plan – and it must be made before the property is acquired, not after.

What does the route look like, step by step?

The engagement follows a defined sequence. Understanding the sequence in advance is the most reliable way to prevent gaps in the document set.

Step 1: Asset and residency mapping. The first deliverable is a complete asset map across both jurisdictions: the title holder of each asset, the governing law of each holding structure, the current residence and domicile position of each principal and spouse, and the location of any existing wills or trust instruments. This step often reveals that assets have moved – by acquisition, restructuring or inheritance – in ways that the original plan did not accommodate.

Step 2: Domicile and residence assessment. Domicile under English law is a complex concept that does not correspond directly to tax residence or physical presence. A principal who was born in Mainland China, holds a Hong Kong permanent identity card and has spent significant periods in England may have a domicile of origin in China, a domicile of dependence acquired in Hong Kong, and a possible domicile of choice in England – each with a different consequence for the moveable estate. This assessment requires input from English-law-qualified counsel, who join the engagement at this step.

Step 3: Forced-heirship risk mapping. Where the family has connections to a civil-law jurisdiction – through the principal's domicile of origin, the law governing the marriage, or the residence of the beneficiaries – we assess the risk that a forced-heirship claim from that system could reach assets held under either the Hong Kong or English structure. The firewall provisions of the reformed Trustee Ordinance are the primary tool on the Hong Kong side; the structure of the English will and any relevant trust must be tested against the same question.

Step 4: Document architecture. The document set typically includes a Hong Kong will for Hong Kong-situated assets, a separate English will for English real property and English-situated moveables, a Hong Kong discretionary trust (where appropriate) for moveable assets requiring multi-generational planning, and powers of attorney under both systems for incapacity scenarios. Where the principal is a company director or trustee in either jurisdiction, the corporate succession implications are addressed separately.

Step 5: Execution and registration. Each document is executed to the formal requirements of its governing law. The English will is executed by English-law counsel; the Hong Kong will and trust instrument are executed with the involvement of locally licensed Hong Kong firms. At this stage, the coordination between the two sets of advisers is critical: a formal non-revocation clause in the English will must be cross-referenced against the Hong Kong will to confirm that neither instrument inadvertently revokes the other.

Step 6: Review triggers. The plan is not a static document. We establish a set of review triggers with the client at the outset: a change in residence or domicile in either jurisdiction, the acquisition or disposal of material assets in either system, a change in the family composition, and any change in the tax-law treatment of the holding structure. For a principal with Cayman or BVI elements to the holding structure, see also our related service on wills and estate plans covering Cayman Islands assets.

The sequence above describes the standard position. Your matter turns on the documents actually in place, the jurisdictions engaged by your family's current residence and asset positions, and the order in which steps need to run. Those details determine where the route is efficient and where it carries risk.

What documents and decisions does the client own?

A well-structured succession plan is not a set of documents that sit in a file. It is a set of decisions that the principal owns and can explain to the people who will be asked to give effect to them. Advisers can draft the instruments; only the principal can make the underlying choices.

The decisions that a principal in this engagement must own are the following. First, who holds the role of executor under each will, and are those individuals willing and able to act in the relevant jurisdiction? An executor appointed under a Hong Kong will must be capable of obtaining a grant of probate in Hong Kong; an executor appointed under an English will must be capable of obtaining a grant of representation from the Probate Registry in England. The two roles can be the same individual, but the individual must understand what each appointment requires.

Second, who are the trustees of any Hong Kong trust, and what is the succession plan for the trusteeship itself? A trust whose sole trustee is the settlor creates a circularity problem on death. A corporate trustee resolves the circularity but introduces a governance question: who controls the corporate trustee, and under what instrument?

Third, how is English real property held, and does that holding structure serve the succession plan? A principal who holds a London property in their own name faces a different succession path than one who holds it through an English holding company or a bare trust. The choice of holding vehicle affects inheritance tax exposure, the availability of relief, and the mechanism by which the property passes on death.

Fourth, what is the plan for incapacity, as distinct from death? A Lasting Power of Attorney under English law and an Enduring Power of Attorney under Hong Kong law serve different functions and have different formal requirements. A principal who loses capacity without instruments in both jurisdictions leaves their affairs in a position where no one has clear authority to act – a situation that is recoverable, but only through a court application that takes time and incurs cost.

Fifth, where a civil-law forced-heirship system is engaged, has the principal made a conscious choice about how to address the potential claim? The firewall provisions of the Trustee Ordinance provide real protection, but that protection is a legal argument, not a guarantee. A principal who chooses to rely on the firewall should understand what that means in practice.

What are the common structural errors in Hong Kong–UK succession planning?

The most common structural error we encounter is what we call the "single will" problem: a principal who has executed a Hong Kong will intending it to cover their entire estate, without appreciating that it will not automatically govern their English real property or their English-situated assets. The result is partial intestacy in England – property passing under rules that the principal did not intend and may not have known about.

The second common error is the inadvertent revocation. A principal who executes an English will after a Hong Kong will, without a carefully drafted non-revocation clause, may – depending on the drafting – have revoked the Hong Kong instrument. The reverse can also occur. In our cross-border practice, we have seen this error produce outcomes that required court applications in both jurisdictions to correct, at a cost to the estate that would have been avoided by a clause of a few words at execution.

The third error is the mismatch between the holding structure and the succession plan. A principal who has built a Hong Kong operating structure below a BVI holding company has created an asset that does not pass in the same way as a directly held asset. The BVI shares pass under the will that governs moveable property situated in the BVI; the Hong Kong opco shares pass under the Hong Kong instrument if situated in Hong Kong. If neither will addresses the BVI shares specifically, or if the BVI jurisdiction is not engaged in the document set, a gap opens.

Fourth, principals who have changed their UK residence status – whether recently or some years ago – often have not revisited the domicile implications of that change. A principal who was previously clear as to domicile in Hong Kong and who has since acquired a home in England, placed children in English schools and spent more than half of each year in the UK may be closer to acquiring an English domicile of choice than they realise. That question changes the succession analysis for the moveable estate and the inheritance tax position materially.

If an earlier structure or document set has already produced an adverse or stalled result – a probate dispute, a failed grant application, an intestacy in one jurisdiction – a fresh read of the position can identify where the gap arose and what routes remain open.

Decision matrix: which instrument, which route, which sequence?

The choice of instrument and route depends on the family's specific asset, residence and domicile profile. The following matrix sets out the principal situations we encounter and the approach each calls for.

Situation A. The principal is Hong Kong-domiciled, holds no English real property, and has moveable assets in England in a brokerage account. Route: a single Hong Kong will covering the moveable estate under the domicile principle; a letter of wishes to the broker identifying the Hong Kong executor; no English will required if the English assets are modest and the brokerage operates a straightforward resealing procedure for Hong Kong grants. Timing: the Hong Kong will governs; the English grant is obtained by resealing the Hong Kong probate, which is a procedural step that allied English counsel can complete without a separate testamentary instrument. Risk: low, provided the English assets do not include real property and the estate is straightforward.

Situation B. The principal is Hong Kong-domiciled, holds a London flat in their own name, and has a Hong Kong trust for the moveable estate. Route: the Hong Kong trust covers the moveable assets; a separate English will governs the London property as immoveable property subject to English law as the lex situs; the English will must contain a non-revocation clause confirming it does not affect the Hong Kong instrument. Timing: the English will must be executed to English formal requirements before the property is acquired or immediately after; delay creates a gap. Risk: medium – the inheritance tax position on the English property requires specific attention; the holding structure for the property (direct title versus an English holding company) should be reviewed before, not after, acquisition.

Situation C. The principal has lived in England for a sustained period and has or is at risk of acquiring an English domicile of choice. Their family includes beneficiaries in a civil-law jurisdiction. Route: the domicile question must be assessed first, before any document is drafted; the result of that assessment governs which system's succession law applies to the moveable estate. The forced-heirship risk from the civil-law jurisdiction is then mapped against the Hong Kong firewall provisions and the English Inheritance Act separately. Timing: this is the most time-sensitive situation, because a change in domicile affects the entire succession analysis retrospectively. Risk: high, without a current domicile assessment.

Situation D. The principal holds assets through a BVI holding structure above a Hong Kong opco, with English real property below an English holding company. Route: the document set must address four asset pools under potentially four governing instruments: BVI shares (governed by the will covering BVI-situated moveable assets), Hong Kong opco shares (governed by the Hong Kong will), English real property (governed by the English will), and the English holding company (governed by the company's articles and the will covering English-situated assets). A single consolidated estate plan must coordinate all four instruments without gap or revocation risk. Timing: the complexity of this structure means the planning engagement typically runs over several months. Risk: high without coordination; the BVI element in particular is frequently overlooked.

Self-assessment checklist: what to review before engaging

The following is a diagnostic checklist for principals with exposure across Hong Kong and the United Kingdom. It is not a substitute for a structured review, but it identifies the positions that most commonly require immediate attention.

• Do you have a will executed in Hong Kong that expressly addresses your Hong Kong-situated assets?
• Do you have a separate will executed in England and Wales, or Scotland, that addresses English real property?
• If you have both, do the non-revocation clauses in each expressly confirm that the later will does not revoke the earlier?
• Has your domicile position under English conflict-of-laws rules been assessed since you last changed your UK residence status?
• Does your estate plan address the position of your spouse under both the Hong Kong and English regimes – and, where applicable, under the law of a third jurisdiction governing your marriage?
• If you hold English real property, is the holding vehicle (direct title, English company, bare trust or other) aligned with both your succession plan and the current inheritance tax position?
• Do you hold shares in a BVI or Cayman holding company, and does the will covering those shares identify them specifically and address the BVI or Cayman element of the estate?
• Do you have powers of attorney in force under both English law and Hong Kong law for incapacity scenarios?
• If your family includes beneficiaries or a surviving spouse in a civil-law jurisdiction, has the forced-heirship risk from that system been mapped against your current structure?
• When were your documents last reviewed? A material change in assets, residence or family composition should trigger a review within six months.

What does the first engagement step look like?

The question we hear most often from principals in this position is not "what should I do?" It is "where do I start?" The answer is a structured diagnostic: a document review and an asset-and-residency map that identifies the gaps, the risks and the sequence of steps needed to close them.

That diagnostic is conducted by our private-wealth desk, drawing on the experience we bring from advising principals across the Hong Kong–UK interface and adjacent corridors. It produces a written assessment of the current position and a recommended document architecture. Locally licensed Hong Kong and English firms join the execution stage; we coordinate the structure and the sequence across the two systems.

We do not offer a standardised product for this engagement. The document set and the route depend entirely on the family's specific asset, residence and domicile position. What we can offer is a structured read of that position and a clear view of the steps needed to move it to a defensible conclusion.
