A private trust for a family with assets Mainlan guide

Succession for a family with significant assets in Mainland China is one of the most structurally demanding problems in Asian private wealth. The question is not simply who inherits. It is how, across which legal systems, and in which order the steps must run to produce an outcome the family can rely on a generation from now.

A private trust governed by Hong Kong law, established under the Trustee Ordinance (Cap. 29, the statute that governs the creation and administration of trusts in Hong Kong, substantially reformed with effect from 1 December 2013), offers a tested mechanism for families whose wealth sits partly or wholly in the Mainland. It separates the asset from the estate, insulates the succession from forced-heirship claims under foreign law, and positions Hong Kong as a neutral, common-law forum sitting one step above the Mainland operating base. The route from decision to settled structure involves seven discrete steps, each with a gate that must be cleared before the next opens.

This guide walks through those steps in sequence. It addresses the cross-border interface between Hong Kong and Mainland China at each stage, names the common mistake practitioners see, and closes with a short decision checklist for the family's advisers.

Why does a family with Mainland assets need a cross-border trust structure?

The core problem is that Mainland China operates a civil-law inheritance system, and Hong Kong operates under common law. They do not produce the same result when a principal dies without a structure in place.

Under Mainland succession law, assets located in the People's Republic of China pass according to PRC rules on intestacy or, where a will exists, through a notarisation and probate process administered by Mainland institutions. That process is sequential, document-heavy, and subject to the distribution rules of PRC succession law – which, unlike Hong Kong, does not give the settlor the freedom to cut out statutory heirs. Where the family holds Mainland property, operating equity, or bank balances in the Mainland, those assets are within the reach of that regime at the moment of the principal's death.

Hong Kong, by contrast, has no forced-heirship regime. The 2013 reform to the Trustee Ordinance strengthened protection of Hong Kong-law trusts against foreign forced-heirship claims. A properly constituted Hong Kong trust, with assets validly transferred into it, is not vulnerable to a competing claim that a Mainland heir was entitled to a fixed share. The firewall works – but only for assets that have actually moved into the trust. Assets that remain registered in the Mainland, in the principal's personal name, are not protected by a Hong Kong trust declaration alone.

This is the structural challenge. The trust is the solution on paper. The cross-border sequencing is the solution in practice.

Our Private Wealth practice regularly advises on this interface. The families we see most often are those who delayed the move until an enforcement or succession event forced the question.

Step 1: Map the asset base and the family's legal footprint

Before any trust document is drafted, the family and its advisers must produce a complete picture of where assets sit, how they are held, and what each principal's legal status creates in terms of exposure.

The mapping exercise has three layers. First, asset location: which assets are registered in the Mainland, which are held through Hong Kong entities, and which are offshore. A Mainland residential property is a fundamentally different structural problem from a Mainland operating company held through a Hong Kong holding entity. The former cannot be transferred out of the Mainland without a real-estate transaction and the associated PRC regulatory steps. The latter may be transferable at the holding-entity level, depending on the corporate structure above it.

Second, the family's tax and residence footprint. Where each family member is tax-resident has direct consequences for the trust. A beneficiary who is a Mainland tax resident may face PRC tax implications on distributions, depending on the characterisation of the income. A settlor who holds Mainland residency status may face constraints on offshore remittance. These are not questions the trust document resolves; they must be addressed in the planning stage.

Third, existing succession instruments. Does the family have a Mainland will? Has it been notarised? Are there joint accounts or properties with survivorship provisions? Each of these interacts with the trust and must be mapped before the structure is designed.

The gate at this step: the family's advisers must be able to say, for each material asset, whether it can be placed in trust directly, whether it must be restructured first, or whether it must remain outside the trust with separate succession arrangements. Without that answer, the next step cannot run.

Step 2: Choose the trust jurisdiction and governing law

The choice of trust jurisdiction is a substantive legal decision, not an administrative preference. It determines which courts have supervision over the trustee, which law governs the trust's validity and administration, and which forced-heirship firewall (if any) applies.

For a family with Mainland assets, Hong Kong is the most common governing-law choice among families for whom the Mainland is the core operating base. The reasons are several. Hong Kong trusts are governed by the Trustee Ordinance, a mature statute with the 2013 reforms in place. Those reforms abolished the rule against perpetuities and excessive accumulations for Hong Kong trusts – meaning the trust does not automatically terminate after a fixed period, which is a material advantage for multigenerational succession planning. The settlor may reserve certain powers over the trust without invalidating it, a flexibility that families with active businesses often require. And Hong Kong courts – the Court of First Instance through to the Court of Final Appeal – are common-law courts with a substantial body of trust jurisprudence and a track record of applying Hong Kong law consistently.

The offshore alternatives – principally the British Virgin Islands and the Cayman Islands – are also used, particularly where the family already has an offshore holding entity. BVI and Cayman trust statutes are well-tested and have their own forced-heirship firewall provisions. The practical question is where the trustee is based and where any enforcement action would run. For a family principally engaged with Hong Kong and the Mainland, a Hong Kong-law trust with a Hong Kong-based trustee produces cleaner procedural alignment.

The gate at this step: the choice of governing law must be documented and defensible. Switching governing law after the trust is settled is a complex exercise. The decision should reflect the family's asset base, the distribution chain's residence profile, and the trustee's capabilities.

Step 3: Restructure Mainland-connected assets before transfer

This is the step most often skipped or underestimated, and it is the most common source of structural failure in cross-border trust planning for Mainland families.

A Hong Kong-law trust can only protect assets that are validly transferred into it. Mainland-registered assets – real property, equity stakes in domestic companies, bank balances held in onshore accounts – are not transferable into a Hong Kong trust by a deed of trust alone. They remain subject to Mainland property law, company law, and foreign-exchange control rules, regardless of what the trust document says.

The practical solution depends on the asset class. For an operating business, the standard route is a holding structure above the Mainland operating entity – typically a Hong Kong company holding the shares in the Mainland entity via a foreign-invested enterprise structure. The Hong Kong company's shares, which are Hong Kong-law property, are then capable of being placed into the Hong Kong trust. The Mainland operating assets are not in the trust directly; the economic interest in them is held through an equity chain that tops out in a trust-held vehicle.

For Mainland real property held personally, the options are narrower. Sale and remittance offshore is one route, subject to foreign-exchange controls and the relevant PRC regulatory steps. Retention in the Mainland with a separate Mainland succession instrument – a notarised will – is another, accepted as a pragmatic parallel mechanism for assets that cannot practicably move. The trust then handles the offshore and Hong Kong-situated assets; the Mainland will handles the Mainland-registered property.

What international advisers often miss is that this restructuring step involves Mainland regulatory approvals and, in some cases, PRC tax filings. Timetabling must reflect the Mainland regulatory cycle, not just the trust documentation timeline. Our desk coordinates with locally licensed firms on the Mainland-side steps; international and Hong Kong counsel can design the structure, but the execution of Mainland restructuring requires locally admitted practitioners.

The gate at this step: no transfer into trust until the underlying asset has been restructured into a form capable of being held by the trust, and all required Mainland regulatory and tax steps have been completed.

How does the Hong Kong trust interact with Mainland succession and forced-heirship rules?

The forced-heirship firewall under the 2013 Trustee Ordinance reform is the legal answer. The practical answer requires understanding when the firewall holds and when it does not.

Hong Kong's 2013 reform provides statutory protection: a trust is not invalidated by reason of it being inconsistent with the forced-heirship or other succession rules of another jurisdiction. This means that a Mainland heir who claims a fixed share of the estate under PRC succession law cannot, in principle, challenge the validity of a properly constituted Hong Kong trust by reference to those PRC rules – at least before Hong Kong courts.

The qualification matters. "Before Hong Kong courts" is doing real work in that sentence. If a Mainland heir brings proceedings before a Mainland court seeking to attach Mainland-registered assets, Hong Kong trust law is of limited direct assistance. The Mainland court will apply Mainland law to assets in its jurisdiction. This is why Step 3 – restructuring Mainland assets out of personal ownership – is the necessary precondition for the firewall to operate in practice, not just in theory.

A second practical point: the relationship between a Hong Kong trust and a Mainland will for the assets that cannot move. Where the family has both a Hong Kong trust (for offshore and Hong Kong assets) and a Mainland notarised will (for Mainland-registered property), the documents must be consistent and cross-referenced. A Mainland will that purports to deal with assets already in a Hong Kong trust creates ambiguity that a Mainland court could exploit. The drafting coordination between the trust deed and any surviving Mainland succession instrument is not a formality; it is a substantive exercise.

For families who have already structured a succession plan in another context, our analysis of the Cayman–Hong Kong interface in the succession planning across Hong Kong and the Cayman Islands matter note illustrates how the same coordination question arises across different offshore jurisdictions.

Step 4: Draft and settle the trust – the document sequence

With the asset map complete, the governing law chosen, and the restructuring steps underway, the trust documentation phase begins. The sequence is specific.

The first document is the trust deed. This establishes the trust, names the trustee and the initial beneficiaries, defines the dispositive powers, sets out any reserved powers the settlor retains, and records the governing law and the seat of administration. For a family with Mainland connections, the deed should expressly state that Hong Kong law governs the trust's validity and administration, and that the forced-heirship firewall provisions of the Trustee Ordinance are engaged. This is not boilerplate; it is a substantive drafting choice that should be made deliberately and recorded.

The second document is the letter of wishes. This is not legally binding on the trustee, but it records the settlor's intentions for distributions and gives the trustee the context it needs to exercise its discretion in accordance with the family's expectations. For cross-border families, the letter of wishes should address the Mainland-connected beneficiaries specifically – their residence status, their access to distributions, and any constraints the settlor places on how funds flow to them.

The third component is the transfer documentation for each asset class. For Hong Kong company shares, a properly stamped transfer instrument. For offshore assets, the relevant assignment or transfer under the law of that jurisdiction. Each transfer must be completed legally and, where applicable, registered.

The gate at this step: the trust is not "settled" until the deed is executed and the assets are validly transferred in. A signed deed with no assets transferred is a shell. Many families sign the deed and then defer the transfers for months. That gap is the window during which the succession exposure they were trying to close remains open.

Step 5: Address the tax position across Hong Kong and the Mainland

Hong Kong has no capital gains tax and no withholding tax on dividends or interest as a general rule. Profits tax applies on a territorial basis to Hong Kong-sourced profits only, at 8.25% on the first HK$2,000,000 of assessable profits and 16.5% above that threshold for corporate entities. There is no estate duty in Hong Kong. For the trust itself, the relevant tax question is how the trustee's income and the beneficiaries' distributions are characterised.

The Mainland-side tax position is a separate analysis. PRC individual income tax applies to Mainland tax residents on their worldwide income, including trust distributions characterised as income. Where a beneficiary is a Mainland national resident in the PRC, the trust structure does not eliminate that exposure; it requires careful planning around how and when distributions are made, and how they are characterised under PRC tax law. This is not a question that Hong Kong or international counsel can fully resolve without input from Mainland tax advisers.

The foreign-sourced income exemption (FSIE) regime – the Hong Kong rule that conditions the exemption of passive foreign-sourced income on economic substance – applies to entities within scope. Families holding income-producing assets through Hong Kong holding entities should assess whether the FSIE conditions are met. The FSIE regime has been in force in its current form from 1 January 2023, as amended.

For MNE-scale family groups, the Pillar Two minimum top-up tax – the Hong Kong implementation of the global minimum tax – is effective for fiscal years beginning on or after 1 January 2025 for in-scope groups with consolidated revenue at or above EUR 750 million. Most private family trusts fall below this threshold, but the point should be confirmed.

The gate at this step: the trust cannot be finalised and funded until the family's tax advisers – on both sides of the border – have confirmed the post-settlement tax position. Structuring the trust without a tax sign-off is a risk that surfaces at distribution time, not at settlement time. By then, unwinding is far more costly.

Our succession planning across Hong Kong and Mainland China resource addresses the tax-succession interaction in more detail for families at this stage of the planning process.

Step 6: Appoint the trustee and establish governance

The trustee's identity and location are structural decisions, not vendor choices. The trustee is the legal owner of the trust assets. It exercises the dispositive powers. It engages with regulators, tax authorities, and courts if the trust is challenged. For a family with Mainland assets, the trustee's ability to navigate the cross-border dimension of that role is a material factor in the structure's long-term resilience.

Hong Kong-based trustees – professional trust companies licensed under the applicable regulatory regime – offer direct access to Hong Kong courts and the common-law system. They are familiar with the Mainland interface and with the practical questions that arise when a Mainland-resident beneficiary requests a distribution or when a Mainland regulatory step needs to be coordinated. They also bring the institutional continuity that individual trustees – family members or the settlor's personal advisers – cannot guarantee across a generation.

A protector may be appointed alongside the trustee. A protector (a person or body with defined supervisory or consent rights over certain trustee decisions, often a trusted family adviser or an independent professional) is a common feature of Hong Kong trusts for larger family structures. The protector's powers should be carefully limited in the deed; an over-powered protector creates a second decision-making layer that can deadlock the trust in a family dispute.

The governance framework should also address trustee removal and replacement. The settlor may reserve the power to remove and replace the trustee under the Trustee Ordinance without invalidating the trust. This is one of the reserved-powers protections introduced by the 2013 reform. For families anxious about loss of control, it is a material comfort – but it should be drafted with care to avoid the reserved power being characterised as rendering the trust a sham.

Step 7: Maintain, review, and document – the ongoing obligations

A trust is not a one-time transaction. It is a continuing legal relationship between the settlor (and the family), the trustee, and the beneficiaries. The ongoing obligations are both legal and practical.

On the legal side, the trustee must maintain proper accounts, act consistently with the trust deed, and administer the trust in accordance with Hong Kong law. Where assets remain connected to the Mainland – through a holding entity above a Mainland opco, for example – the trustee must manage that corporate chain actively, including attending to annual filings, substance requirements, and the FSIE conditions where relevant.

On the practical side, the letter of wishes should be reviewed and updated as the family's circumstances change. A beneficiary who moves from the Mainland to Hong Kong, or to a third country, changes the distribution picture. A new generation of beneficiaries – children born after the trust is settled – should be added to the class of potential beneficiaries (if the deed permits) or addressed in an updated letter of wishes. The trust deed itself may need to be amended, with trustee consent and, in some cases, court approval.

The cross-border dimension of this maintenance obligation is real. Changes in PRC foreign-exchange control rules, PRC individual income tax regulations, or the FSIE regime can alter the economics of the trust structure without any change to the trust deed itself. Annual reviews with coordinated Hong Kong and Mainland advisers are not optional housekeeping; they are the mechanism by which the structure stays fit for purpose across the regulatory cycles of two different legal systems.

What families underestimate is the compounding cost of deferred maintenance. A trust that was well-structured in year one but not reviewed for five years can accumulate compliance deficiencies, outdated distribution instructions, and tax exposures that are materially more difficult to unwind than they would have been to address at the time.

Decision checklist: is your family ready to settle a Hong Kong private trust?

Before committing to the trust-settlement process, the family's advisers should be able to answer yes to each of the following questions. A "no" at any point is a gate: the process should pause until the gap is addressed.

Has a complete map of the family's assets been produced, identifying each asset's location, registration, and legal form?
Has each Mainland-registered asset been assessed for whether it can be restructured into a form transferable into trust, or whether it requires a separate Mainland succession instrument?
Has the governing law been chosen deliberately and documented, with Hong Kong selected (or a reasoned alternative identified) on the basis of the family's asset base and distribution chain?
Have Mainland regulatory approvals and PRC tax filings required for the restructuring step been identified and sequenced into the implementation timeline?
Has a tax analysis been completed across Hong Kong and the Mainland, covering the FSIE position, the Pillar Two threshold check, and the Mainland individual income tax position of each beneficiary?
Has a trustee been identified, assessed for cross-border capability, and engaged to review the proposed structure before the deed is drafted?
Is there a plan for the ongoing maintenance of the trust – governance reviews, annual trustee reporting, and coordinated cross-border adviser engagement?

The checklist is not exhaustive. It reflects the points at which families most frequently stall or make decisions they later need to unwind. The sequence matters: moving to Step 4 (documentation) before Step 3 (restructuring) is the single most common structural error in this practice area.

Consider a scenario our desk has seen more than once. An Asian family with manufacturing assets in Guangdong and residential property in Hong Kong engaged an offshore adviser who drafted a BVI trust deed and declared the Hong Kong property transferred in. The Mainland manufacturing equity, held personally by the patriarch, was never restructured. The patriarch died two years later. The BVI trust held the Hong Kong property; the Mainland assets passed through PRC intestacy, distributed to heirs the patriarch had specifically intended to exclude. The Hong Kong property was protected. The Mainland business was not. The distinction was entirely structural – and entirely avoidable.

The sequence described in this guide is designed to prevent that outcome. Each gate exists because the corresponding risk is real and, once realised, largely irrecoverable.

Frequently asked questions

How long does a private trust for a family with assets in Mainland China usually take?

The timeline depends primarily on the restructuring step. Where Mainland assets must be reorganised into a holding structure before transfer into trust, the Mainland regulatory and tax process is the critical path – and that process can take several months to over a year, depending on the asset class and the relevant approvals. The trust documentation itself, once the asset map and governing-law choice are settled, can be completed relatively quickly. Families should plan for the full process, including Mainland restructuring, to take a minimum of six to twelve months in straightforward cases, longer where the asset base is complex. Parties should verify the current Mainland regulatory timetable with locally admitted counsel before committing to a specific timeline.

How does the cross-border element affect a private trust for a family with assets in Mainland China?

The cross-border element affects virtually every stage of the process. The Trustee Ordinance's forced-heirship firewall protects assets validly transferred into a Hong Kong trust from foreign succession claims – but that protection only reaches assets that have actually moved into the trust and are situated in a jurisdiction where a Hong Kong court's determination would be effective. Mainland-registered assets remain subject to PRC law unless restructured out of personal ownership. The cross-border element also affects the tax position, the distribution mechanics, and the ongoing maintenance obligations, all of which require coordinated advice across both legal systems.

What is the first step in a private trust for a family with assets in Mainland China?

The first step is a complete map of the family's asset base and legal footprint – identifying where each material asset is registered, how it is held, what each principal's residence and tax status creates in terms of exposure, and whether any existing succession instruments (Mainland wills, joint accounts, survivorship provisions) are in place. Without that map, the structure cannot be designed correctly. Families who begin with the trust document and work backwards frequently discover, at the restructuring stage, that the structure they have settled cannot hold the assets they intended to protect.
