How to approach forced-heirship and cross-border

A family's wealth rarely sits in one place. The principal may reside in Hong Kong, hold operating companies in the Mainland, park liquid assets through a BVI holding entity, and own real property in a jurisdiction with its own inheritance rules. Each of those nodes is subject to the succession law of the place where it sits – or, in some systems, the law of the principal's nationality or domicile. When those systems conflict, the conflict is not theoretical. It determines who inherits, in what share, and whether a carefully prepared estate plan survives contact with a foreign court.

Forced-heirship risk is the exposure of a cross-border estate to mandatory statutory inheritance shares that cannot be overridden by a will or a trust. The governing instrument in Hong Kong is the Trustee Ordinance (Cap. 29), reformed with effect from 1 December 2013 to strengthen protection of Hong Kong-law trusts against foreign forced-heirship claims. That protection, however, does not automatically extend to assets held outside Hong Kong, and it has no effect on the succession law of a jurisdiction that asserts its own mandatory rules over assets situated there.

This guide sets out a step-by-step approach for principals and their in-house advisers. It covers the map exercise, the structural options, the sequencing logic, the common mistake, and a decision checklist for the first meeting with counsel.

Step 1: Map the family's jurisdictional footprint before anything else

The first task is not to pick a trust jurisdiction. It is to identify every legal system with a potential claim over the estate – by reason of asset location, the principal's nationality, the principal's domicile, or the residence of intended beneficiaries.

Most advisers in our cross-border practice find that principals underestimate how many systems are in play. A Hong Kong-resident principal who holds a portfolio through a Cayman fund, owns a flat in the United Kingdom, has shares in a Singapore holding company, and retains nationality of a civil-law jurisdiction with forced-heirship rules is exposed to at least four legal systems at once. Each has its own view on which law governs succession to that asset class.

The map exercise produces a matrix: asset class, location, the legal system likely to govern succession to that asset, and whether that system imposes mandatory heirship rules. Civil-law systems across Continental Europe, the Middle East, and many parts of Asia apply forced-heirship regimes that reserve a fixed proportion of the estate for specified heirs – typically children and a surviving spouse – regardless of the principal's wishes. Common-law systems, including Hong Kong, do not impose equivalent mandatory shares. That distinction drives every structural decision that follows.

Do not proceed to Step 2 until the map is complete. An incomplete map produces an incomplete structure, which is the most common source of post-death disputes in our experience.

Step 2: Identify which forced-heirship exposures are real and which are notional

Not every civil-law connection creates enforceable forced-heirship exposure. The question is whether a foreign court's judgment awarding a mandatory share to a claimant heir could be recognised or enforced against the assets. That depends on three variables: the location of the assets, the jurisdictions in which the intended beneficiaries will seek to enforce, and the enforcement mechanisms available between those systems.

Consider a principal who is a national of a country with forced-heirship rules but has been domiciled in Hong Kong for many years. Under Hong Kong conflict-of-laws principles, succession to movable property generally follows the law of domicile. If the principal is domiciled in Hong Kong at the date of death, Hong Kong law governs succession to movables. Hong Kong law has no forced-heirship regime. The nationality-based claim of the foreign system may carry limited practical weight against movables held through Hong Kong structures – but weight is not zero where assets also exist in the foreign jurisdiction, where a beneficiary holds nationality there, or where an heir is prepared to litigate in the foreign court and then seek cross-border recognition.

Real exposure exists where: assets are physically situated in a forced-heirship jurisdiction; the principal retains domicile or habitual residence in such a jurisdiction; the estate plan has not been reviewed since a change of residence; or a disgruntled heir is likely to litigate in a jurisdiction whose judgments could be recognised elsewhere. Notional exposure – a nationality connection with no assets, no domicile, and no practical enforcement path – requires monitoring but not immediate structural action. Counsel on our desk regularly work through this triage before recommending any structural step.

Step 3: Understand Hong Kong's position as a succession planning hub

Hong Kong offers a well-tested common-law trust and succession environment. The 1 December 2013 reforms to the Trustee Ordinance removed the rule against perpetuities and the rule against excessive accumulations for Hong Kong trusts, abolished forced heirship under Hong Kong law, and introduced a statutory firewall: a Hong Kong-law trust is not invalidated by reason of any foreign law that would impose forced-heirship obligations on the settlor's estate. The settlor may also reserve certain powers without vitiating the trust, a feature relevant to principals who are reluctant to relinquish control entirely.

Those reforms make a Hong Kong trust a considered choice for a principal whose primary concern is protecting the estate plan against a foreign forced-heirship claim asserted after death. The firewall operates by treating any foreign judgment or order purporting to impose a forced-heirship entitlement on trust assets as unenforceable against the trustee under Hong Kong law.

The limits are equally important. The firewall protects assets held in the Hong Kong trust. It does not protect assets that were never settled into the trust, assets that the principal withdrew before death, or assets located in a jurisdiction that applies its own mandatory rules directly to the asset without requiring recognition of a foreign judgment. A Hong Kong trust is a necessary but not sufficient measure. It must be combined with a plan for every asset class on the map produced in Step 1.

For principals whose succession planning intersects with questions of asset protection more broadly, our practice note on asset protection and UAE exposure sets out the structural considerations where Gulf-based assets are part of the picture.

Step 4: Choose the structural approach for each asset class

The structural options across the asset map are not uniform. Different asset classes require different instruments, and the choice of instrument affects both the forced-heirship protection achieved and the administrative and tax costs incurred.

For liquid financial assets and investment portfolios, a trust settled under a robust common-law jurisdiction is the primary instrument. Hong Kong, the BVI, and the Cayman Islands are the most commonly used trust seats for Asian-connected families. The choice between them turns on the trustee market, the governing-law firewall strength, and the interaction with the principal's residence and domicile. Hong Kong is increasingly preferred where the principal and the beneficiaries are based in Asia and the ongoing administration needs to remain accessible.

For operating companies and shareholdings, a holding structure interposed between the principal and the operating entities – typically a BVI or Cayman holding company held by the trust – separates beneficial ownership from the operational layer and allows succession to occur at the trust level rather than through a contested probate or succession process in the operating jurisdiction. This structural approach also positions the estate plan to work alongside a considered choice of trust jurisdiction for the Asia-based family.

For immovable property, the position is more constrained. Succession to real property is governed almost universally by the lex situs (the law of the place where the property is situated). A forced-heirship jurisdiction can apply its mandatory rules to property located within its borders without needing to recognise a foreign judgment. Holding real property through a local company can convert an immovable into a movable for succession purposes – the principal's interest becomes shares in the company, not land directly – but this technique is jurisdiction-specific and requires local tax and legal analysis before use.

For life insurance and retirement assets, the beneficiary designation in the policy or plan document controls distribution and typically passes outside the estate entirely, avoiding both probate and forced-heirship exposure in most systems. The adequacy of existing beneficiary designations is one of the first items we check.

Step 5: Sequence the documentation in the right order

Sequencing is where estate plans most commonly fail. The structural work and the documentation work must proceed in a defined order. The gate at each step is whether the prior step is effective and whether the next step depends on it.

The sequence runs as follows. First, the will or wills – most cross-border principals require separate wills for assets in different jurisdictions, each drafted to govern only the assets in that jurisdiction and to disclaim any effect on assets elsewhere. A single global will that attempts to govern all assets in all jurisdictions creates conflict-of-laws complexity and, in some cases, revokes earlier wills that were functioning correctly. Second, the trust deed – executed with full attention to the choice of governing law, the powers reserved to the settlor, the scope of the firewall provision, and the trustee's discretion over distributions. Third, the settlement of assets – the process of actually transferring assets into the trust structure, which is the step most commonly left incomplete. Fourth, the company-level documentation – shareholder registers, board resolutions, and constitutional documents updated to reflect the new holding chain. Fifth, ongoing reviews – the structure must be revisited when the principal changes residence, when the family map changes, when a new jurisdiction enters the picture, or when there is a material change in the applicable law.

The gate at the trust-execution step is capacity and domicile. A trust settled when the principal lacked mental capacity, or when their domicile is disputed, is vulnerable to challenge. The gate at the asset-settlement step is completeness: assets not settled into the trust fall outside its protection. Our desk regularly identifies incompletely settled trusts as the primary structural vulnerability in an otherwise sound plan.

Step 6: Identify the common mistake and how to avoid it

The most common mistake in cross-border succession planning is the gap between the paper structure and the operational reality. A trust deed exists. The trustee is appointed. The legal advice has been given and billed. But the assets have not been transferred. The will has not been updated to reflect the trust's existence. The beneficiary designations on the insurance policies still name the principal's estate rather than the trust. The holding company shares are still registered in the principal's name.

What happened? The principal completed the planning phase and then, in the ordinary course of business, did not complete the implementation phase. The structure that was meant to provide protection provides none, because nothing was actually settled into it.

The discipline required is implementation management: a closing checklist, tracked by counsel, with confirmation of each transfer, each updated register, and each amended designation. The family office or the principal's CFO needs to be a participant in this process, not merely a recipient of the legal advice. A well-designed structure that is half-implemented is not a defence against a forced-heirship claim. It may be evidence that the principal intended to make a plan but did not.

The second common mistake is failing to review. Forced-heirship laws change. A jurisdiction the principal considered benign may introduce new rules. The principal's domicile may shift, bringing a new legal system into play. A beneficiary's residence may change, introducing a new enforcement risk. The structure that was correct at implementation may be inadequate five years later. Annual reviews – or reviews triggered by any change in the family's jurisdictional footprint – are not optional.

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. For a structured assessment of your cross-border succession position, write to us at info@lockhartyip.com.

Step 7: Work through the decision checklist

The checklist below is designed for the first conversation between a principal and their counsel. It does not replace legal advice. It establishes the information base from which advice can be given.

Residence and domicile: Where is the principal currently resident? Where is domicile currently located? Has either changed in the past five years, or is a change anticipated?

Nationality: Does the principal hold nationality of a country with a forced-heirship regime? Is that country likely to assert jurisdiction over assets or over the principal's succession? Are the intended beneficiaries nationals or residents of any forced-heirship jurisdiction?

Asset map: For each asset class – financial assets, shares, real property, life policies, pension or retirement accounts, intellectual property, operating entities – where is it located? In whose name is it held? How does succession to it currently operate?

Existing documents: Is there a will? Is it current? Does it cover all asset classes? Does it interact correctly with any trust that exists? Are beneficiary designations on policies and retirement accounts current and intentional?

Trust status: If a trust exists, what assets have actually been settled into it? When was it last reviewed? Does the governing law provide a forced-heirship firewall? Are the trustee's powers and the distribution framework consistent with the principal's current intentions?

Family circumstances: Are there children from a prior relationship whose claims under a foreign system may conflict with the current estate plan? Is there a surviving spouse in a jurisdiction with mandatory spousal rights? Are any beneficiaries minors whose interests require independent consideration?

Timing: Is there a planned change of residence, a significant transaction, or a new asset acquisition that should trigger a review of the estate plan before the event rather than after?

If an earlier filing, structure or enforcement attempt 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.

Decision matrix: situation, instrument, route, and risk

The structural decision follows from the map, not the other way around. The matrix below sets out the standard positions.

Where the principal is domiciled in Hong Kong, holds assets primarily through BVI or Cayman entities, and has no material assets in a forced-heirship jurisdiction, the primary instrument is a Hong Kong-law trust with a comprehensive firewall clause. The risk is low once implementation is complete. The route is trust settlement, will review, and beneficiary-designation update. Timing is straightforward.

Where the principal holds nationality of a civil-law forced-heirship jurisdiction and retains assets there – real property, bank accounts, business interests – the position is materially different. The Hong Kong firewall does not extend to those assets. The route requires local estate-planning instruments in each asset jurisdiction, potentially combined with a Hong Kong or common-law trust for the offshore and liquid assets. The risk is the gap between the two layers: assets that fall into neither. The timing trigger is any change in the principal's domicile or in the composition of the asset base.

Where the principal is planning a change of residence from a forced-heirship jurisdiction to Hong Kong, the transition period carries elevated risk. The old domicile may continue to assert jurisdiction for a period after physical departure, and the new domicile may not yet be established. The route is to complete the structural documentation before departure where possible, and to obtain advice in both the origin and destination jurisdictions on the point at which domicile shifts. The risk of acting too late is that a forced-heirship claim is asserted under the old system before the new structure is in place.

Where immovable property in a forced-heirship jurisdiction forms a significant part of the estate, a company interposition must be analysed in that jurisdiction specifically. The tax cost of interposition, the local rules on company-held property, and the risk that the jurisdiction treats the company structure as a sham must all be assessed by locally qualified advisers before the structure is adopted. We coordinate that analysis with allied counsel and our private wealth practice as the cross-border layer.

Frequently asked questions

What documents are needed for forced-heirship and cross-border succession risk?

The core documents are: a current will or set of jurisdiction-specific wills covering each material asset class; a trust deed if a trust is used, with confirmation of which assets have been settled; updated beneficiary designations on all life policies and retirement accounts; and a complete asset schedule showing each asset, its jurisdiction, and the name in which it is currently held. Where a holding structure is in place, the company register and constitutional documents for each entity in the chain should also be reviewed. The adequacy of the documentation depends on the jurisdictions in play; parties should verify the current position in each relevant system before acting.

Which jurisdiction's law applies to forced-heirship and cross-border succession risk?

There is no single answer. Succession to immovable property is generally governed by the law of the place where the property is situated. Succession to movables generally follows the law of the deceased's domicile at the date of death, though some civil-law systems apply the law of nationality instead. Where a trust holds the assets, the trust's governing law governs the distribution of trust assets, and Hong Kong's statutory firewall under the Trustee Ordinance protects Hong Kong-law trusts against foreign forced-heirship claims. The practical answer depends on the principal's domicile, the asset locations, and the systems likely to be invoked by potential claimants.

What is the first step in forced-heirship and cross-border succession risk?

The first step is a full jurisdictional map of the family's assets, residence, domicile, and nationality connections. Before any structural advice can be given, counsel needs to know which legal systems have a potential claim over the estate and whether any of those systems impose mandatory heirship rules. That map drives all subsequent decisions: the choice of trust jurisdiction, the approach to real property, the design of the holding structure, and the sequencing of the documentation. Acting on structure before completing the map typically produces gaps – assets left outside the structure that remain exposed to the claims the plan was designed to prevent.
