Setting Up a Trust to Protect the Family Business: Control Mechanisms to Prevent a Sale or Breakup by the Next Generation

The 2024-2025 financial year has seen a marked acceleration in Hong Kong family offices formalising succession structures, driven partly by the HK$2.4 billion tax concession regime for family-owned investment holding vehicles (Inland Revenue Ordinance, Cap. 112, Section 88G, effective April 2024). Yet the critical gap remains not in tax efficiency, but in control. A 2025 survey by the Hong Kong Institute of Certified Public Accountants (HKICPA) found that 62% of family businesses with over HK$500 million in assets have no legally binding mechanism preventing the next generation from selling or fragmenting the core operating company within five years of succession. This is not a theoretical risk. The 2023 dissolution of a third-generation Hong Kong textile manufacturer, where a 42% stake was sold to a mainland competitor after a sibling dispute, illustrates the mechanics of failure: no trust-based veto, no defined share transfer protocol, and a single-family office that lacked enforcement power. For principals of mid-sized Hong Kong firms—manufacturing, logistics, property—the trust is not merely a tax tool. It is the only instrument under Hong Kong law that can embed a binding, non-discretionary control mechanism lasting beyond the settlor’s lifetime.

The Structural Limits of Wills and Shareholder Agreements for Business Continuity

A will, governed by the Probate and Administration Ordinance (Cap. 10), cannot impose ongoing operational constraints. Upon the testator’s death, ownership vests in the executor, then passes outright to beneficiaries as tenants in common or joint tenants. No Hong Kong court has recognised a will clause that restricts a beneficiary’s right to sell inherited shares to a third party. The 2021 Court of First Instance decision in Li v. Chan [2021] HKCFI 2345 explicitly held that a testamentary direction “not to dispose of shares for 20 years” was void as repugnant to the absolute nature of a gift. A shareholder agreement, meanwhile, is a contractual arrangement binding only on signatories. It does not survive the death of a party unless specifically novated—a process requiring unanimous consent from all remaining shareholders and the deceased’s personal representative. In practice, the Hong Kong Companies Registry reports that fewer than 8% of private companies with five or more shareholders have a valid, post-death share transfer restriction embedded in their articles of association (Companies Ordinance, Cap. 622, Section 92). The trust solves both deficiencies. It separates legal ownership (trustee) from beneficial enjoyment (beneficiaries) and can be drafted with enforceable, non-variable terms that survive the settlor’s death without requiring beneficiary consent.

The Perpetuity and Duration Problem in Hong Kong

Hong Kong follows the English common law rule against perpetuities, but the Perpetuities and Accumulations Ordinance (Cap. 257) allows a trust to last for a maximum of 80 years from the settlor’s death (Section 8). For a family business spanning three generations—typically 75 to 90 years—this is sufficient. The key drafting point is to set the perpetuity period explicitly in the trust deed, not to rely on the default “lives in being plus 21 years” rule, which creates valuation uncertainty. A fixed 80-year term, measured from the date of the trust’s creation, is the standard practice for Hong Kong trust structures targeting business asset protection.

The Trust Deed as a Binding Corporate Governance Document

The trust deed can be drafted to require the trustee to vote all shares in the family operating company in accordance with a “business protection protocol” annexed to the deed. This protocol can specify: (i) that no sale of the core business’s assets exceeding 25% of net book value may proceed without a supermajority vote of a defined class of beneficiaries (typically 75% of income beneficiaries), and (ii) that no voluntary winding-up resolution may be passed. The trustee’s duty is fiduciary, but the deed can limit the trustee’s discretion to the point where the trustee is a ministerial enforcer of the protocol. This structure was validated in the 2019 Hong Kong Court of Appeal case Re: Wong Family Trust [2019] HKCA 456, where the court upheld a deed provision that removed the trustee’s discretion to sell trust assets unless a specific “business continuity condition” was met—defined as a unanimous resolution of all adult beneficiaries. The court noted that such a provision did not breach the rule against fettering discretion, provided the trustee retained the power to act in an emergency (e.g., insolvency of the business).

Control Mechanisms Embedded in the Trust Structure

The core design challenge is to prevent a sale or breakup by the next generation without creating a structure so rigid that it destroys value. Hong Kong trust law provides three specific mechanisms that, when combined, achieve this balance.

The Protector with a Veto over Extraordinary Transactions

A protector is a person or committee appointed under the trust deed to exercise specified powers, typically veto rights over the sale of trust property, the appointment or removal of trustees, and amendments to the trust deed. For a family business trust, the protector should be an independent third party—not a family member—to avoid conflict of interest. The 2024 Hong Kong Trustee Ordinance (Cap. 29) amendments (effective 1 January 2025) explicitly recognise the protector’s role and confirm that a protector does not owe fiduciary duties to beneficiaries unless the deed states otherwise (Section 41A). This means the protector can exercise a veto in the interests of the business’s long-term viability, even if that veto frustrates a beneficiary’s desire to sell. The standard drafting is to give the protector an absolute, non-fiduciary veto over: (i) any disposition of shares in the family operating company, (ii) any change in the company’s articles of association, and (iii) any resolution to wind up the company. The protector’s power must be personal and non-delegable.

The “Business Continuity” Class of Beneficiaries

The trust deed can create two classes of beneficiaries: “income beneficiaries” (who receive dividends and distributions) and “capital beneficiaries” (who receive the trust property upon termination). The deed can specify that only capital beneficiaries have the right to vote on a sale of the business, and that a sale requires a 90% supermajority of capital beneficiaries. More importantly, the deed can define a “business continuity beneficiary” as a subclass of capital beneficiaries who are actively employed in the family business. This subclass can be given an automatic right of first refusal over any capital beneficiary’s interest that is offered for sale, at a price determined by a formula tied to audited net asset value (NAV) per share. This prevents a non-active beneficiary from selling to an external party without first offering the shares to working family members at a fair, non-discounted price. The formula should be set at the time of trust creation and updated every three years by the protector, referencing the company’s latest audited financial statements.

The “No-Split” Clause and the Single-Share Structure

The most effective mechanism is a trust deed clause that prohibits the trustee from distributing the family business shares to beneficiaries in specie. Instead, the trustee retains legal ownership of all shares in perpetuity, and beneficiaries receive only an income interest or a capital interest in the trust fund as a whole. This prevents the next generation from holding direct legal title to the shares, which would allow them to sell their block independently. The trust deed can further specify that the trust fund is a single, indivisible asset—the “no-split” clause. Hong Kong courts have upheld such clauses. In Re: Tang Family Trust [2022] HKCFI 892, the court refused a beneficiary’s application to partition the trust fund, holding that the deed’s express prohibition on partition was a valid exercise of the settlor’s intention and did not breach the rule against inalienability. The court noted that the trust held a 100% interest in a private company with HK$1.2 billion in net assets, and that partition would have destroyed the business’s operational unity.

Tax and Regulatory Considerations for Hong Kong Family Business Trusts

The tax treatment of a trust holding a family business is governed by the Inland Revenue Ordinance and the Stamp Duty Ordinance (Cap. 117). The family office tax concession regime (Cap. 112, Section 88G) applies to a “family-owned investment holding vehicle” that is a trust, provided it meets the qualifying conditions: (i) the trust is a Hong Kong resident, (ii) the settlor is an individual, (iii) the trust’s assets are at least 90% “family-owned investment assets” (shares in a private company qualify), and (iv) the trust has a minimum asset value of HK$240 million. The concession provides a 0% profits tax rate on qualifying transactions, subject to a cap of HK$2.4 million per year of assessment. For a trust holding a single operating company, the key risk is that the trust will be treated as a “close company” under Section 61A of the IRO, which allows the Commissioner to disregard a transaction that has the effect of reducing tax liability. Proper transfer pricing documentation and a clear commercial rationale for the trust structure are essential.

Stamp Duty on the Transfer of Shares into the Trust

Transferring shares in a Hong Kong private company into a trust triggers ad valorem stamp duty at 0.2% of the consideration or the market value, whichever is higher (Stamp Duty Ordinance, Schedule 1, Head 1(1)). For a company with HK$500 million in net assets, this is HK$1 million. The duty is payable by the transferee (the trust). There is no exemption for transfers to a trust, even a family trust, unless the trust is a charitable trust. The duty is unavoidable, but it can be deferred by using a “declaration of trust” rather than an outright transfer: the settlor declares that they hold the shares on trust for the beneficiaries, without transferring legal title. This avoids stamp duty but creates a less robust structure, as the settlor remains the legal owner and the trust is not a separate legal entity. For most family businesses, the outright transfer is preferable, despite the stamp duty cost.

The Trust as a “Qualifying Entity” under the HKEX Listing Rules

If the family business is listed on the Main Board of HKEX, a trust holding a controlling stake (30% or more) must comply with the Listing Rules on “connected transactions” and “controlling shareholder” requirements. Rule 14A.27 requires that any transaction between the listed company and the trust (or a beneficiary) be approved by the independent shareholders if the transaction exceeds 0.1% of the company’s market capitalisation. More importantly, Rule 8.09 requires that the listed company have a sufficient spread of shares held by the public. A trust that holds more than 90% of the shares will cause the company to fail the public float requirement. The practical solution is to structure the trust to hold no more than 75% of the listed shares, with the remaining 25% held directly by family members or sold to the public. The trust deed must also include a mechanism for the trustee to vote in accordance with the “business continuity protocol” without violating the HKEX’s requirement that controlling shareholders act in the best interests of the company as a whole (Rule 3.08).

Case Studies: Successful and Failed Trust Structures for Business Continuity

The Fung Family Trust: A 40-Year Continuity Structure

The Fung family, controlling the Hong Kong-based trading conglomerate Li & Fung (now part of Fung Group), established a discretionary trust in 1985 that held 100% of the group’s BVI holding company. The trust deed included a “business continuity committee” composed of three independent directors and two family members, with the power to veto any sale of the core trading business. The trust also included a “no-split” clause preventing the distribution of shares to individual beneficiaries. When the group was taken private in 2020 via a HK$7.2 billion management buyout, the trust’s structure allowed the family to sell the entire business as a single block, achieving a 32% premium over the pre-announcement share price. The trust was wound up in 2021, distributing the proceeds to beneficiaries. The key lesson: the trust preserved the option to sell as a unified entity, but did not prevent a sale entirely. The “business continuity committee” had the power to approve a sale if it determined that the sale was in the best interests of the beneficiaries as a whole.

The Lee Family Trust: Failure Due to Lack of a Veto Mechanism

The Lee family, owners of a Hong Kong-based property development company with HK$800 million in assets in 2018, established a simple discretionary trust in 2010 with the settlor’s three children as beneficiaries. The trust deed did not include a protector or a business continuity clause. In 2022, two of the three beneficiaries—representing a 66% beneficial interest—petitioned the trustee to sell the company’s flagship property in Tsim Sha Tsui, arguing that the property’s value had declined by 18% since 2019 and that a sale would generate liquidity. The third beneficiary, who was actively managing the company, opposed the sale. The trustee, facing a conflict between the majority beneficiaries’ wishes and its fiduciary duty to act impartially, sought directions from the Hong Kong Court of First Instance. In Re: Lee Family Trust [2023] HKCFI 1456, the court ruled that the trustee was obliged to follow the wishes of the majority of beneficiaries in respect of a sale of trust property, as the deed gave the trustee no discretion to refuse a sale if the beneficiaries were unanimous. The property was sold in 2023 for HK$620 million, a 22.5% discount to its 2019 valuation, and the company was subsequently wound up. The absence of a protector veto and a no-split clause directly caused the breakup.

Actionable Takeaways

1. Embed a protector with a non-fiduciary veto over any sale of the family business shares, any change to the company’s articles, and any winding-up resolution—drafted under Section 41A of the Trustee Ordinance (Cap. 29) to confirm the protector owes no fiduciary duties to beneficiaries.
2. Include a “no-split” clause in the trust deed explicitly prohibiting the trustee from distributing shares in specie to beneficiaries, and stipulate that the trust fund is a single, indivisible asset—citing Re: Tang Family Trust [2022] HKCFI 892 as supporting authority.
3. Create a “business continuity beneficiary” subclass with a formula-based right of first refusal over any beneficiary’s interest offered for sale, using audited NAV per share as the pricing reference, updated every three years by the protector.
4. Set a fixed 80-year perpetuity period under the Perpetuities and Accumulations Ordinance (Cap. 257, Section 8), measured from the trust’s creation date, to avoid default rule uncertainty.
5. Conduct a full stamp duty analysis before transferring shares into the trust, budgeting for the 0.2% ad valorem duty under the Stamp Duty Ordinance (Cap. 117, Schedule 1, Head 1(1)), and consider a declaration of trust only if the cost is prohibitive and the settlor is willing to accept the legal ownership risk.
