A practical guide to a private trust for a family with assets in the United Kingdom

A private trust structured around assets in the United Kingdom requires a family to resolve three distinct legal questions before any deed is drafted: which law governs the trust, how the United Kingdom's own rules interact with that choice, and what succession and tax consequences flow through to each jurisdiction where a family member is resident or domiciled. For a family with a Hong Kong connection, the interface between common-law trust principles on both sides and the two countries' different approaches to residence, domicile and forced-heirship is where the structure is won or lost.

This guide walks through the decision in sequence. Each step carries a gate – a condition that must be met before the next step opens. The guide is instructional. It reflects the position in practice rather than any single matter, and the reader should verify current positions before acting.

What is the decision a family actually faces at the outset?

The first question is not which trust to form. It is whether a trust is the right instrument at all, given the family's asset map and the jurisdictions in which members actually live.

A private family trust is a legal arrangement under which one or more trustees hold assets for the benefit of defined beneficiaries. In a cross-border context – particularly where assets sit in the United Kingdom and the family has a Hong Kong or Asian nexus – the trust is doing several jobs at once. It separates legal title from beneficial enjoyment. It can impose a succession plan across jurisdictions that would otherwise apply their own rules. It can provide a degree of asset protection. And, where it is properly structured, it can avoid the delays and costs of grant-of-probate proceedings in multiple countries.

The alternatives are not trivial. A will, or a network of jurisdiction-specific wills, can achieve some of the same objectives at lower cost and with less ongoing administration. A family investment company, structured through a Hong Kong or offshore holding entity, can hold United Kingdom assets without triggering the full trust architecture. And for families whose United Kingdom exposure is limited to a single property, a bare nominee structure may be sufficient.

The decision turns on three factors: the value and type of United Kingdom assets involved, the number of jurisdictions in which family members are tax-resident or domiciled, and the degree of control the settlor wishes to retain. Where all three are material, a trust structured under a well-developed common-law regime – whether Hong Kong, the BVI, the Cayman Islands or another recognised centre – is usually the instrument of choice.

Our cross-border practice regularly advises families at exactly this preliminary stage. The answer is rarely obvious from the asset map alone. The succession picture, the residence picture and the tax picture have to be read together before the instrument is chosen.

How does the United Kingdom's legal position interact with a cross-border trust?

The United Kingdom applies its own rules to trusts that hold United Kingdom-situated assets, and those rules operate regardless of the law the trust instrument chooses to govern its internal affairs.

The most significant point for international families is the United Kingdom's inheritance tax regime. The United Kingdom charges inheritance tax on the worldwide assets of individuals who are domiciled (permanently settled, in the sense of a legal concept distinct from tax residence) in the United Kingdom. It also charges inheritance tax on United Kingdom-situated assets regardless of the owner's domicile. That second limb catches every family, regardless of where they live. A Hong Kong-resident settlor placing a United Kingdom property into a trust does not automatically remove that property from the United Kingdom inheritance tax net. The analysis depends on whether the trust is within the relevant relevant property regime (the United Kingdom trust-taxation mechanism that charges periodic and exit charges rather than treating trust assets as part of the settlor's estate) and whether any exemption or relief applies.

A second point is the United Kingdom's approach to the validity and administration of foreign trusts. The United Kingdom's private international law rules – broadly following the Hague Convention on the Law Applicable to Trusts and on their Recognition – will generally recognise a trust governed by a foreign law, provided that law has a recognisable trust concept and the trust was validly constituted under it. In practice, a Hong Kong-law trust or a BVI-law trust holding United Kingdom assets will be recognised in the United Kingdom courts. The trustee's title to the United Kingdom assets, and the beneficiaries' beneficial interests, will be treated accordingly.

The third point is forced heirship. The United Kingdom has no forced-heirship regime in the civil-law sense. A UK-domiciled individual may leave assets freely. But for a family with members who are domiciled or habitually resident in a jurisdiction that does impose forced heirship – parts of continental Europe, much of the Middle East, some civil-law Asian jurisdictions – the trust structure has to be tested against those regimes as well. A claim under a foreign forced-heirship rule may be asserted against United Kingdom-situated assets in circumstances where the foreign court has personal jurisdiction over the trustee or a beneficiary.

Hong Kong, by contrast, has no forced-heirship regime. Under the reforms that took effect on 1 December 2013 under the Trustee Ordinance (Cap. 29), Hong Kong strengthened the firewall protecting Hong Kong-law trusts against foreign forced-heirship claims. That positioning makes a Hong Kong-law trust a practical choice for families who want a common-law governing law with explicit statutory protection against such claims.

What is the sequence, and what is the gate at each step?

The sequence for establishing a private trust with a United Kingdom asset base has six distinct steps. Each carries a gate – a condition or decision that must be resolved before the next step is viable.

Step 1: Map the family's succession and residence position across all relevant jurisdictions. Before any trust structure is designed, the family's domicile, residence and citizenship position must be documented across every jurisdiction in which a principal family member has a current or historical connection. This includes the settlor, the intended trustees, and the primary beneficiaries. The gate here is a clear, written summary of each person's position. Without it, no governing-law choice can be made safely.

Step 2: Identify the United Kingdom assets and their ownership structure. The type of United Kingdom asset matters. A residential property held directly by an individual raises different issues from shares in a United Kingdom company, a portfolio held through a United Kingdom broker, or a participation in a United Kingdom limited-liability partnership. The gate is a complete and legally precise description of each asset, its current titleholder, and any existing security, restriction or co-ownership arrangement.

Step 3: Choose the governing law and the trust jurisdiction. This is the structural decision. The choice of governing law determines which rules apply to the trust's internal affairs – constitution, validity, trustee powers, beneficiary rights, amendment and termination. The principal options for a cross-border family with Hong Kong and United Kingdom connections are Hong Kong law (under the Trustee Ordinance), BVI law, or Cayman Islands law. Each has a well-developed trust statute, recognised courts, and a professional trustee market. Hong Kong law carries the additional benefit of the statutory forced-heirship firewall described above. The gate is a governing-law choice confirmed with advice from counsel on the cross-border implications – not a default selection driven by where the trustee is incorporated.

Step 4: Appoint a trustee and define the trust structure. A professional corporate trustee (a trust company licensed in the chosen jurisdiction) is standard for trusts of any complexity. The trust deed defines the powers of the trustee, the class of beneficiaries, the distribution discretions, and any reserved powers for the settlor. Under Hong Kong law, the 2013 reform of the Trustee Ordinance confirmed that a trust is not invalidated by the settlor reserving certain powers – including powers to direct investment, to add or remove beneficiaries, or to change the governing law. The gate is a trust deed reviewed and signed by independent legal counsel familiar with both the chosen governing law and the United Kingdom asset position.

Step 5: Transfer the United Kingdom assets into the trust. This step engages United Kingdom law directly. Transferring real property into a trust requires a disposition by deed and registration at HM Land Registry. Transferring shares or securities requires registration in the trustee's name in the relevant register. Each transfer may trigger United Kingdom stamp duty land tax on real property, or ad valorem stamp duty on shares where those shares represent United Kingdom-situated assets. The tax position at the point of transfer must be confirmed before the transfer is executed. The gate is confirmation, from United Kingdom-qualified advisers, of the tax and registration steps and their sequencing.

Step 6: Establish the ongoing administration and reporting structure. A trust does not operate itself. The trustee requires current information on the United Kingdom assets, on the tax position in each relevant jurisdiction, and on any material change in the family's residence or domicile. For United Kingdom assets, the trustee may have reporting obligations to HM Revenue & Customs under the United Kingdom's trust registration service. The gate is a documented administration plan, including who provides the tax and reporting work in each jurisdiction, and who coordinates across them.

Our desk has mapped this sequence across a number of matters involving Hong Kong families with real property and investment portfolios in the United Kingdom. The sequence is consistent. The difficulty lies not in any single step, but in the interaction between steps three and five – the governing-law choice and the transfer mechanics – where a mismatch creates structural risk that is difficult to correct later.

What is the common mistake, and how does the route avoid it?

The most common mistake in cross-border trust structuring for families with United Kingdom assets is treating the governing-law choice as an administrative decision rather than a structural one.

Families, and sometimes their advisers, select the trust jurisdiction based on the location of the professional trustee – or simply use the jurisdiction where an earlier holding structure was incorporated. A BVI or Cayman trustee is appointed because the family already has a BVI holding company. The trust deed follows. The United Kingdom assets are transferred. And the governing law of the trust has been chosen without any analysis of how it interacts with the United Kingdom's inheritance tax regime, the family's domicile position, or the forced-heirship rules of any other jurisdiction where a beneficiary is located.

The consequence is typically not discovered until the settlor dies or until a beneficiary asserts a claim. At that point, the trust may be exposed to United Kingdom inheritance tax charges that a properly sequenced structure would have mitigated, or a forced-heirship claim from a third jurisdiction may have a stronger foothold than it should.

The route described in this guide avoids the mistake by treating Step 3 – the governing-law decision – as the critical gate. The choice is made after the family map is documented (Step 1) and after the assets are identified (Step 2), not before. And it is confirmed with cross-border advice, not delegated to the trustee's standard jurisdiction.

A second, related mistake is failing to coordinate the trust structure with the settlor's existing will or wills. A trust that covers the United Kingdom assets, but a will that does not reflect the trust's existence, can produce conflicting succession outcomes. The two instruments have to be read together, and any conflict resolved before either is finalised.

For a deeper treatment of forced-heirship risk and how it crosses into Hong Kong and common-law trust structures, see our analysis on forced heirship and cross-border succession risk.

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.

Micro-scenario: Hong Kong family with a London property and a multi-jurisdiction beneficiary class

A family principal resident in Hong Kong held a London residential property directly in their own name and a portfolio of United Kingdom-listed securities through a United Kingdom broker. Three adult children were resident in, respectively, Hong Kong, the UAE and a civil-law European jurisdiction. The family came to our desk in the context of a planned relocation by the principal, which would have affected their domicile position.

The immediate question was whether the existing structure – direct ownership plus a broad will – adequately covered the family's succession objectives given the European child's position under the forced-heirship rules of their jurisdiction of residence.

We mapped the family's position across all four jurisdictions. The European jurisdiction's forced-heirship rules could, on the facts, have reached the United Kingdom assets through the child's habitual residence and the absence of an effective trust firewall. A Hong Kong-law trust was established, with the United Kingdom property and portfolio transferred into it. The governing-law choice was confirmed after analysis of the United Kingdom inheritance tax position and the interaction with the European forced-heirship rules. The transfer mechanics for the real property were handled with United Kingdom-qualified advisers. The result was a structure that aligned the succession outcome across all three children's jurisdictions – qualitatively, not through any guaranteed outcome.

Decision checklist: assessing readiness for the trust structure

Before instructing counsel to proceed, a family should be able to answer the following questions with documented precision.

• Is the domicile and tax-residence position of the settlor, the intended trustees, and each primary beneficiary documented, including any historical connection to the United Kingdom?
• Are all United Kingdom assets identified, with their current titleholder, type, and any encumbrance or co-ownership arrangement?
• Has the governing-law choice been made with cross-border advice, not by default?
• Has the interaction between the proposed trust structure and the United Kingdom's inheritance tax regime been confirmed by United Kingdom-qualified tax advisers?
• Has the forced-heirship position in every jurisdiction where a beneficiary is domiciled or habitually resident been assessed?
• Is there a coordinated plan for the transfer of United Kingdom assets, including the tax and registration steps in sequence?
• Does the settlor's existing will, or wills, reflect the proposed trust structure, and have any conflicts been resolved?
• Is there a documented administration plan, including tax reporting obligations in the United Kingdom and any other relevant jurisdiction?

A "no" to any of these questions is a gate that has not yet been cleared. The trust should not be executed until all eight are answered in the affirmative.

If an earlier structure, will or enforcement attempt has produced an adverse or stalled result, a second read can identify the strategic error and the routes still open. To discuss how the sequence applies to your cross-border position, contact info@lockhartyip.com.

Where does this sit in the broader private wealth practice?

A private trust for a family with United Kingdom assets is rarely a stand-alone instruction. In practice, it sits within a broader private wealth position that typically includes at least one holding structure (for any corporate or investment assets), a residence or relocation question, and a succession plan that has to work across multiple legal systems simultaneously.

The Hong Kong platform is well-suited to the coordinating role. As a common-law jurisdiction with no forced-heirship regime, no capital gains tax, no inheritance tax, and a well-developed trust statute that has been substantively reformed as recently as 1 December 2013, Hong Kong provides a coherent legal base for a family whose assets and members are spread across the United Kingdom, Asia and the offshore centres.

The interaction with the foreign-sourced income exemption (FSIE) regime – under which foreign-sourced income received in Hong Kong by multinationals and, in certain circumstances, by trusts and their trustees may be subject to Hong Kong profits tax unless substance conditions are met – is a point that requires attention where the trust is expected to receive and distribute income from United Kingdom sources. The FSIE regime has been in force from 1 January 2023, as amended, and the position should be confirmed before the trust is funded.
