A practical guide to pre-immigration

A principal who moves jurisdiction without restructuring first does not simply change address. They change the legal system that governs their assets, their succession, and in many cases their family's exposure to forced-heirship claims. The question is not whether to plan – it is whether to plan before the residence clock starts or after, when the options are narrower and the costs are higher.

Pre-immigration and pre-residence wealth planning is the structured process of reviewing and, where necessary, reorganising a family's asset-holding and succession arrangements before a change of residence becomes effective in the destination jurisdiction. The governing instruments vary by jurisdiction, but in Hong Kong the principal tools include the Trustee Ordinance (Cap. 29) – substantially reformed with effect from 1 December 2013 – and, for offshore holding layers, the trust and company statutes of the British Virgin Islands and the Cayman Islands. The planning window closes the moment residence is established; steps taken after that point may be characterised as post-migration restructuring and treated differently by the destination authority.

This guide sets out the decision the reader faces, the sequence of steps in order, the gate at each stage, and the mistakes that most frequently derail a well-intended plan. It is written from a cross-border perspective, with Hong Kong as the planning hub and the family's wider jurisdictional map – Mainland China, the BVI, the Cayman Islands, the UAE, and European succession-law jurisdictions – as the working terrain.

What decision does the principal actually face?

The decision is not simply where to live. It is a layered question: which law will govern the succession of each asset class; which jurisdiction will tax the income and gains generated by those assets; and whether the current ownership structure – often a Mainland-connected operating group with BVI or Cayman entities above it – is suited to the new residence environment.

Most of the principals our desk sees arrive with a combination of directly held real estate, offshore companies, and family-held operating entities. The residence move – whether to Hong Kong, the UAE, Singapore, or a European jurisdiction – changes the succession and tax analysis for each layer simultaneously. The family's existing adviser in the origin jurisdiction often has strong command of one system. They rarely have command of two or three at once.

The practical decision tree looks like this. First: does the destination jurisdiction impose a forced-heirship rule that would reach the family's assets? Second: does the family's current ownership structure create a taxable event on the death of the principal in the destination? Third: is there a trust or similar arrangement already in place, and if so, does it comply with the substance and situs (the legal concept of where an asset is situate for private-international-law purposes) requirements of the destination?

If the answer to any of those questions is uncertain, the pre-residence planning window is not optional. It is the last point at which the structure can be adjusted without reference to the destination jurisdiction's rules.

How do forced-heirship rules interact with Hong Kong trust law?

Hong Kong law has no forced-heirship regime, and the 2013 reform of the Trustee Ordinance strengthened the protection of Hong Kong-law trusts against foreign forced-heirship claims. That makes Hong Kong a structurally sound base for families moving from civil-law jurisdictions where réserve héréditaire (the French civil-law concept of a protected share of an estate reserved for certain heirs) or equivalent rules would otherwise reach a significant share of the estate.

The practical point is sequencing. A trust settled under Hong Kong law before the settlor acquires residence in a forced-heirship jurisdiction can, in most cases, be governed by Hong Kong law as the lex situs of the trust and protected by the statutory firewall provisions in the Trustee Ordinance. The position reverses once the settlor is resident in the foreign jurisdiction: a trust settled after that point may be challenged under the foreign jurisdiction's domestic rules, depending on the conflict-of-laws analysis applied by the foreign court.

This is one of the two areas where our cross-border practice sees the most avoidable damage. A family intending to relocate from a European or Middle Eastern civil-law jurisdiction to Hong Kong frequently defers trust settlement until after they have established tax residence in Hong Kong, at which point the origin jurisdiction's forced-heirship rules still apply to assets that were within their estate at the date of departure. The trust can still be settled, but it needs to address a more complex set of prior claims.

The mirror problem exists for families moving to a forced-heirship jurisdiction from Hong Kong or from offshore. Assets that pass into a structure after the settlor becomes resident in the destination may be caught by the destination's mandatory rules regardless of the governing law chosen for the trust.

What is the correct sequence, and where is the gate at each step?

Pre-immigration planning follows a defined sequence. The sequence matters because each step conditions the one that follows, and some steps cannot be taken once residence is established.

Step one: jurisdictional map. The starting point is a complete picture of every jurisdiction in which the family holds assets, owes obligations, or has beneficial interests. This includes the Mainland, where a significant proportion of the asset base in our cross-border practice is located, as well as offshore entities, real estate titles, and any existing trust or foundation structures. The map must identify the succession law that currently applies to each asset class and the succession law that will apply after the move.

Step two: succession-law gap analysis. For each asset class, the gap between the current position and the intended post-residence position is assessed. The gate at this step is whether the gap can be closed by restructuring before residence is established. Assets that are illiquid – typically Mainland operating companies and real estate – present the hardest cases, because a reorganisation may require regulatory approvals that take time. If the timeline for the residence move is fixed, the gap analysis must be completed before the structural work begins, not alongside it.

Step three: ownership-structure review. The existing BVI or Cayman holding entity is reviewed for compliance with the destination jurisdiction's substance and anti-avoidance rules. Many destination jurisdictions – the UAE and several European countries among them – look through offshore structures when assessing the principal's taxable estate or applying their controlled-foreign-company rules. A structure that was adequate for the origin jurisdiction may need an additional Hong Kong intermediate layer, or a trust-held holding arrangement, to meet the substance requirements of the destination.

The gate here is the economic-substance regime. Both the BVI and the Cayman Islands operate economic-substance regimes that apply to entities engaged in certain activities. A reorganisation that changes the activity type of an existing entity may trigger a substance-compliance review in the offshore jurisdiction before the move can proceed.

Step four: trust or equivalent arrangement. Where the succession-law gap analysis indicates that a trust or similar arrangement is required, it is settled before residence is established in the destination. The choice of governing law – Hong Kong, the BVI, the Cayman Islands, or another common-law trust jurisdiction – is driven by the situs of the primary assets, the forced-heirship risk in the origin and destination, and the family's long-term governance preferences. Hong Kong trust law, post the 2013 reform, is particularly well-suited to families with Mainland-connected assets, given that the Trustee Ordinance provides statutory protection for settlor-reserved powers and has abolished the rule against perpetuities, removing a structural constraint that affected earlier Hong Kong trusts.

Step five: source-of-funds documentation. Pre-immigration planning in the current compliance environment is inseparable from anti-money laundering (AML) documentation. Assets transferred into a trust or a new holding structure at the time of a residence move are subject to enhanced customer due-diligence scrutiny by the receiving institution. The gate at this step is completeness of source-of-funds documentation before any transfer is initiated. In our cross-border practice, delays at this step are the single most common cause of a planning window being missed.

Step six: tax-position review. The interaction between the origin jurisdiction's exit-tax rules and the destination's entry-year rules must be reviewed before the move. Hong Kong's territorial tax system – profits tax on Hong Kong-sourced profits only, no capital gains tax, no withholding tax on dividends – makes it an efficient destination. But the origin jurisdiction may impose an exit charge on the departure of a long-term resident. The timing of the trust settlement, the corporate reorganisation, and the actual departure date each carry a separate tax consequence that must be modelled before any step is taken.

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.

What does the cross-border interface look like in practice?

For a family with Mainland assets and a BVI holding entity moving from, say, a CIS jurisdiction to Hong Kong, the planning interface looks like this. The Mainland assets sit beneath the BVI entity and cannot easily be re-titled before the move. The BVI entity holds the economic interest. The trust, when settled, sits above the BVI entity and holds the shares.

The cross-border question is: will a Hong Kong court, or a Mainland people's court, recognise the trust's ownership of the BVI shares in a succession event? The answer turns on the Mainland's conflict-of-laws rules for succession to movable property, the governing law of the trust, and whether the trust was constituted before the Mainland-resident settlor's death.

Since the Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance (Cap. 645) came into force on 29 January 2024, the pathway for recognising Hong Kong civil judgments in the Mainland – and vice versa – has materially improved. A well-structured trust, with Hong Kong as its governing law and the trust deed executed before any Mainland succession event, is in a stronger position than an ad hoc testamentary disposition that relies on the Mainland courts applying foreign succession law for the first time in a contested matter. The planning, in other words, is not abstract. It affects the enforceability of the family's succession arrangement in the jurisdiction where most of the underlying value sits.

A second scenario our desk sees is a family with a UAE-resident principal and a Cayman holding structure looking to establish a secondary residence in Hong Kong. The UAE's civil-law succession rules apply by default to certain asset classes held by Muslim nationals. The planning question is whether the Cayman trust structure, settled before Hong Kong residence is established, is sufficient to ring-fence those assets from the UAE succession regime. The answer depends on whether the UAE courts would treat the trust as a valid disposition of the principal's estate or would look through it as a simulated transfer. This is an area where allied counsel admitted in the relevant jurisdiction must be engaged in parallel with the Hong Kong structuring work.

These two scenarios share a common feature. In each case, the cross-border analysis is not a single-system question. It requires simultaneous command of the trust law in the planning jurisdiction, the succession law in the origin jurisdiction, and the conflict-of-laws rules in both the origin and the destination. That is the planning gap that pre-immigration counsel – as opposed to a domestic adviser in any one of those jurisdictions – exists to fill.

What do most principals get wrong?

The most common mistake is timing. Specifically, it is the assumption that the planning can proceed in parallel with – or even after – the move. In our cross-border practice, we regularly see files where the principal has already established tax residence in the destination, often inadvertently, before the trust has been settled or the holding structure reviewed. At that point, the options narrow considerably and the costs – legal, tax, and compliance – increase substantially.

A second common error is treating pre-immigration planning as a purely tax exercise. The tax analysis is important, and the interaction between Hong Kong's territorial system and the origin jurisdiction's exit-tax rules must be modelled carefully. But the succession and forced-heirship dimension often carries larger financial consequences than the tax dimension. A family that loses a contested succession claim in the origin jurisdiction may lose a larger share of the estate than any reasonable exit-tax liability.

Third: many principals underestimate the source-of-funds compliance burden. A trust settled with significant assets – whether shares in a Mainland operating group, real estate, or investment portfolios – will require the trustee to complete full customer due diligence on the settlor and the source of the assets. If that documentation is not assembled before the trust is settled, the trustee cannot accept the assets, and the planning window may be lost. The documentation requirement applies equally to the offshore holding entity review at Step three.

Finally, the myth that a simple will, drafted in the destination jurisdiction, is sufficient for a family with a multi-jurisdictional asset base is one of the more persistent misconceptions our desk encounters. A will is a testamentary instrument that operates on assets in the jurisdiction of its execution and, where recognised, in other jurisdictions. It does not override a foreign forced-heirship regime. It does not create the structural separation between the principal's estate and the holding entities that a well-drawn trust achieves. And it does not provide the continuity-of-control mechanisms – successor trustee provisions, letter of wishes, protector appointment – that allow the family governance arrangement to function after the principal's death without court intervention.

If an earlier filing, structure or succession arrangement produced an adverse or stalled result, a second read can identify the strategic error and the routes still open. Write to info@lockhartyip.com to discuss the position.

How does Hong Kong's trust law position compare with offshore alternatives?

The choice of trust jurisdiction – Hong Kong, the BVI, or the Cayman Islands – is driven by four factors: the situs of the primary assets, the forced-heirship risk, the substance requirements of the destination jurisdiction, and the practical administration of the trust over time.

Hong Kong trust law, governed by the Trustee Ordinance, has several distinctive features that make it well-suited to the Mainland-connected family. The abolition of the rule against perpetuities and the rule against excessive accumulations, effected by the 2013 reform, removes the 80-year structural constraint that affected earlier Hong Kong trusts and made BVI or Cayman trusts the default for long-term family-wealth arrangements. The statutory firewall against foreign forced-heirship claims, also strengthened in 2013, provides explicit protection for Hong Kong-law trusts from civil-law succession challenges. And the statutory protection for settlor-reserved powers means that a Hong Kong trust can accommodate the governance preferences of a first-generation principal – retaining a degree of oversight over investment and distribution decisions – without the trust being invalidated on the grounds that the settlor has retained effective control of the assets.

BVI and Cayman trust structures remain appropriate where the primary assets are themselves held in BVI or Cayman vehicles, where the trust is part of a fund structure, or where the destination jurisdiction's substance requirements make an offshore-administered trust preferable for the principal's overall exposure. Both jurisdictions operate economic-substance regimes, and the choice of jurisdiction for the trust entity must account for those regimes from the outset.

For families moving to Hong Kong from a civil-law jurisdiction, the combination of a Hong Kong-law trust above a BVI or Cayman holding entity – with the trust settled before residence is established – is a well-tested architecture in our cross-border practice. It separates the succession question (governed by Hong Kong trust law) from the corporate-holding question (governed by the offshore jurisdiction) and from the underlying-asset question (governed by the Mainland or other operating-jurisdiction law). Each layer is governed by the system best suited to it, and the interfaces between layers are documented at the time of settlement rather than litigated after a succession event.

What is the decision checklist before moving?

The following checklist reflects the planning sequence described above. It is not a substitute for legal advice on the specific facts, but it is a useful self-assessment for a principal or in-house adviser reviewing a proposed move.

Is the jurisdictional map of the family's assets, beneficial interests, and obligations complete and current?
Has the succession law applicable to each asset class in the origin jurisdiction been identified, including any forced-heirship or reserved-share rules?
Has the succession law applicable to each asset class in the destination jurisdiction been identified, and does it differ materially from the current position?
Has the gap between the two succession-law positions been assessed, and is it capable of being closed before residence is established?
Have the offshore holding entities been reviewed for economic-substance compliance and for compatibility with the destination jurisdiction's controlled-foreign-company or look-through rules?
Has a trust or equivalent arrangement been considered, and if so, has the governing law been chosen to maximise protection against forced-heirship claims in both the origin and destination?
Is the source-of-funds documentation for the assets to be transferred into the trust or new structure complete and available?
Has the interaction between the origin jurisdiction's exit-tax rules and the destination's entry-year rules been modelled, and has the timing of each step been set accordingly?
Have allied counsel admitted in each relevant jurisdiction been engaged to advise on the domestic-law dimension of the plan?
Is the planned date of residence establishment known, and is the full sequence of planning steps capable of being completed before that date?

A principal who can answer each of those questions with confidence has done the planning work. A principal who cannot answer one or more of them has identified the priority task before the move.

Frequently asked questions

What is the first step in pre-immigration and pre-residence wealth planning?

The first step is a complete jurisdictional map of every asset class, beneficial interest, and obligation the family holds across all relevant countries. Without a clear picture of where value sits and which succession law currently applies to each asset, it is not possible to identify the gaps that the planning must close. The map must be completed before any structural work – trust settlement, holding-entity review, or source-of-funds documentation – begins, because each subsequent step depends on it.

How does the cross-border element affect pre-immigration and pre-residence wealth planning?

The cross-border element is the central driver of the planning. A move from one jurisdiction to another changes the succession law, the tax position, and in many cases the forced-heirship exposure of the family's assets simultaneously. Hong Kong's Trustee Ordinance – as reformed in 2013 – provides a well-tested basis for trust structures that protect assets from foreign forced-heirship claims. The interface between Hong Kong trust law and the Mainland's conflict-of-laws rules for succession, and between the origin jurisdiction's exit-tax rules and Hong Kong's territorial tax system, must both be addressed before residence is established. Parties should verify the current position in each jurisdiction before acting.

What are the main risks in pre-immigration and pre-residence wealth planning?

The principal risks are mistiming, under-scoping, and compliance failure. Mistiming means establishing residence before the structural work is complete, at which point the destination jurisdiction's rules apply and the options narrow. Under-scoping means treating the exercise as a tax matter only, leaving succession and forced-heirship exposure unaddressed. Compliance failure means initiating a trust settlement or holding-entity transfer without complete source-of-funds documentation, causing the trustee to reject the assets and the planning window to be lost. All three risks are avoidable if the planning sequence is followed before the residence clock starts.
