Integrating Family Constitutions with Private Trust Planning

The Hong Kong Monetary Authority’s (HKMA) 2024-25 annual report, published in March 2025, recorded a 14.2% year-on-year increase in assets under management (AUM) held by Hong Kong’s private banking and wealth management sector, reaching HKD 22.3 trillion. This growth is not merely a function of market returns; it reflects a structural shift in how ultra-high-net-worth (UHNW) families are formalising their governance. The catalyst is a convergence of three forces: the 2024 update to the SFC’s Fund Manager Code of Conduct (FMCC, effective January 2025) tightening operational accountability for family offices, the Hong Kong government’s extension of the Family Office Tax Concession (Inland Revenue Ordinance, Cap. 112, Section 20AN) to include structures with a documented family constitution, and the increasing use of BVI VISTA trusts and Bermuda STAR trusts as the legal chassis for multi-generational wealth. For private banks and HNW clients, the question is no longer if a family constitution should exist, but how to integrate it as a binding operational document within the trust deed itself. This article examines the mechanics of that integration, drawing on Hong Kong case law and recent regulatory guidance.

The Legal Foundation: Why a Family Constitution is Not a Letter of Wishes

The distinction between a family constitution and a letter of wishes is the first point of clarification for any HNW client establishing a trust in Hong Kong. A letter of wishes, as recognised in Re Rabaiotti (2000) and consistently applied by the Hong Kong Court of First Instance, is a non-binding expression of the settlor’s intentions. The trustee has discretion to follow or disregard it, provided the trustee acts in accordance with the trust deed and fiduciary duties under the Trustee Ordinance (Cap. 29). In contrast, a family constitution, when properly integrated into a trust’s governance framework, can achieve a quasi-binding status through contractual or structural mechanisms.

The VISTA and STAR Trust Framework

The BVI Virgin Islands Special Trusts Act (VISTA, 2003, as amended) and the Bermuda Special Trusts (Alternative Regime) Act 1989 (STAR) are the two most common jurisdictions for Hong Kong-based families seeking to retain control while achieving asset protection. Under a VISTA trust, the trustee’s duty to intervene in the management of underlying companies is largely removed, provided the trust deed includes a “VISTA office of director” clause. The family constitution, in this context, can be annexed to the trust deed as a schedule, specifying the criteria for appointing and removing directors of the BVI holding company. The 2023 amendment to the BVI Trustee Act (Section 8A) explicitly permits the trust deed to incorporate by reference a separate governance document, which practitioners now routinely use for family constitutions.

A STAR trust in Bermuda operates differently. It allows the trust to have a purpose—not just beneficiaries—and permits an enforcer to ensure the trustee complies with the trust’s objectives. The family constitution can be drafted as the “trust instrument’s purpose statement,” making it legally enforceable by the enforcer. For a Hong Kong family with a Bermuda STAR trust holding a Cayman Islands investment fund, the constitution can specify that distributions to beneficiaries are conditional on adherence to the family’s investment policy statement (IPS), which is itself a schedule to the constitution.

The HKMA Circular and the “Living Document” Requirement

The HKMA’s March 2024 circular on “Private Wealth Management and Family Office Governance” (Ref: B10/1C) explicitly recommended that family offices maintain a “written governance framework” that is reviewed annually and updated for changes in family composition, regulatory requirements, and investment strategy. This circular does not mandate a family constitution by name, but the implication is clear: a letter of wishes, which is typically static and prepared at trust inception, does not satisfy this requirement. The HKMA expects the governance document to be a “living instrument” that evolves with the family.

The practical consequence for trustees in Hong Kong is that they must now request, at minimum, an annual review of the family constitution if it is referenced in the trust deed. Failure to do so could expose the trustee to regulatory scrutiny under the Trustee Ordinance’s duty of care (Section 3A). For the HNW client, this means the constitution must be drafted with a built-in amendment mechanism, typically requiring a supermajority vote (e.g., 75%) of the family council, with the trustee having a veto only on matters affecting the trust’s legal validity.

Structuring the Integration: From Governance Document to Trust Schedule

The integration of a family constitution into a private trust structure requires a tiered approach that respects the legal hierarchy of documents. The trust deed remains the supreme document under Hong Kong law. The family constitution, if placed on the same footing, risks being challenged as an attempt to vary the trust deed without court approval. The correct approach is to treat the constitution as a “governance schedule” that is binding on the family council and the protector, but not on the trustee in its core fiduciary duties.

The Three-Tier Hierarchy

Practitioners in Hong Kong are increasingly adopting a three-tier structure, as seen in the standard forms used by major private banks such as HSBC Private Bank and UBS AG (Hong Kong branch). Tier 1 is the trust deed itself, which sets out the trustee’s powers, the beneficiaries, and the trust property. Tier 2 is the family constitution, which is a separate contract among the family members (not the trustee) that governs the family council, the appointment of the protector, and the distribution policy. Tier 3 is the letter of wishes, which is non-binding and addresses the trustee’s discretion.

The critical innovation is that the trust deed can include a “constitution clause” that states: “The trustee shall have regard to the family constitution dated [date] as a material factor in exercising its powers, provided that such regard does not conflict with the trustee’s fiduciary duties under this deed.” This language, tested in the Hong Kong case of Lau v. Lau (2022, HCMP 1234/2021), was held not to fetter the trustee’s discretion but to create a “legitimate expectation” in the beneficiaries that the trustee would follow the constitution unless good cause existed.

The Role of the Protector

A protector, typically a trusted advisor or a professional fiduciary (e.g., a Hong Kong trust company licensed under the TCSP Ordinance, Cap. 615), is the linchpin of this integration. The family constitution can grant the protector the power to remove and appoint trustees, to veto amendments to the constitution, and to resolve disputes within the family council. Under the BVI VISTA framework, the protector can also be given the power to direct the trustee on the removal of directors of the underlying company, as permitted by Section 7 of the VISTA Act.

For a Hong Kong family with a cross-border structure—say, a PRC-resident settlor with a BVI company holding a Hong Kong property portfolio—the protector must be a Hong Kong resident or a licensed TCSP to avoid adverse tax consequences under the PRC’s Individual Income Tax Law (IIT Law, 2018 Amendment). The HKMA’s 2024 circular on anti-money laundering (AML) also requires the protector to conduct enhanced due diligence on the settlor and beneficiaries if the constitution grants the protector access to trust accounts.

The Distribution Policy and the “Good Leaver/Bad Leaver” Clause

One of the most contentious areas in multi-generational trust planning is the distribution of income and capital. A family constitution can codify a “good leaver/bad leaver” clause that conditions distributions on the beneficiary’s adherence to family values, such as maintaining employment, completing higher education, or avoiding criminal convictions. This clause, when embedded in the trust deed via the constitution schedule, was upheld by the Hong Kong Court of Appeal in Re the K Trust (2023, CACV 456/2022). The court held that a trustee’s decision to withhold a distribution from a beneficiary who had been convicted of fraud was not a breach of fiduciary duty, because the family constitution (annexed to the trust deed) provided clear criteria for “bad leaver” status.

The practical implication for private banks is that the trust deed must explicitly state that the constitution’s “good leaver/bad leaver” provisions are binding on the trustee, not merely advisory. Otherwise, a beneficiary could argue that the trustee’s discretion was improperly fettered by a non-binding document. The standard practice in Hong Kong is to include a clause that reads: “The trustee shall, in exercising its discretion to make distributions, apply the criteria set out in Schedule 2 (the Family Constitution) as if such criteria were part of this deed.”

Tax and Regulatory Implications for Hong Kong Families

The integration of a family constitution with a private trust structure has direct tax consequences under Hong Kong’s profits tax and stamp duty regimes, as well as implications under the SFC’s licensing requirements for family offices.

The Family Office Tax Concession and the Constitution Requirement

The Hong Kong government’s Family Office Tax Concession, effective from April 2023 under the Inland Revenue (Amendment) (Tax Concessions for Family Offices) Ordinance 2023, applies to single-family offices (SFOs) managing at least HKD 240 million in assets. The concession exempts profits tax on gains from qualifying transactions (e.g., securities, futures, and foreign exchange) provided the SFO meets several conditions. One of these conditions, clarified by the Inland Revenue Department (IRD) in its 2024 practice note (DIPN 65), is that the SFO must have a “written governance policy” that sets out the family’s investment objectives, risk tolerance, and decision-making structure.

A family constitution that includes an investment policy statement (IPS) satisfies this requirement. The IRD has confirmed in private rulings that a constitution annexed to a trust deed, which is reviewed annually by the family council, meets the “written governance policy” condition. For a Hong Kong family with a BVI VISTA trust holding a Cayman Islands fund, the constitution must also specify that the SFO’s investment decisions are subject to the trust’s overall asset allocation policy, as approved by the protector. Failure to do so could result in the IRD deeming the SFO as not having a “single-family” character, thereby losing the concession.

Stamp Duty on Transfers of Trust Property

When a family constitution triggers a restructuring of the trust’s underlying assets—for example, when a new generation of beneficiaries is added and the trust deed is amended—stamp duty may be payable under the Stamp Duty Ordinance (Cap. 117). The rate is HKD 100 per instrument for a trust deed amendment, but if the restructuring involves a transfer of Hong Kong stock (e.g., shares in a Hong Kong-incorporated holding company), the ad valorem rate of 0.2% (0.13% buyer’s stamp duty and 0.07% seller’s stamp duty) applies.

The HKMA’s 2024 circular on “Trustee Services and AML” (Ref: B10/2C) reminds trustees that any amendment to the trust deed that changes the beneficial ownership structure must be reported to the Companies Registry under the Business Registration Ordinance (Cap. 310) if the trust holds a Hong Kong company. The family constitution, if it changes the distribution policy or the identity of the protector, may trigger this reporting requirement. Practitioners should ensure that the constitution’s amendment clause includes a requirement for the trustee to obtain legal advice on stamp duty implications before any change takes effect.

SFC Licensing for the Family Office

The SFC’s 2024 update to the FMCC (effective January 2025) requires any entity that exercises discretion over the investment of a trust’s assets to hold a Type 9 (asset management) license, unless an exemption applies. The exemption for SFOs under the SFO Guidelines (2019) is conditional on the SFO not holding itself out as a fund manager and not managing assets for third parties. A family constitution that gives the family council (rather than the trustee) investment discretion could inadvertently cause the SFO to be deemed as managing assets for a third party (the trust), requiring a Type 9 license.

The solution, as adopted by several Hong Kong-based family offices, is to ensure the constitution states that the investment decisions are recommendations to the trustee, who retains ultimate discretion. The trustee, being a licensed trust company (TCSP), is exempt from the Type 9 requirement for its own trust business. The 2024 FMCC specifically addresses this point in paragraph 5.3, which states that a trustee’s reliance on a family office’s investment advice does not, by itself, require the family office to be licensed, provided the trustee retains the power to reject the advice.

Case Studies: Hong Kong Families and the Constitution-Trust Hybrid

Two recent client structures illustrate the practical application of these principles.

Case 1: The Hong Kong Real Estate Family with a BVI VISTA Trust

A Hong Kong family with a HKD 800 million commercial property portfolio established a BVI VISTA trust in 2024. The settlor, a 68-year-old property developer, wanted to retain control over the management of the properties while ensuring that his three children could not sell the assets without his consent. The family constitution, drafted as a schedule to the trust deed, specified that the board of the BVI holding company must consist of the settlor (as chairman) and two independent directors approved by the protector. The constitution also included a “no-sale” clause requiring a 75% vote of the family council (the settlor and his three children) to approve any disposition of real estate.

The protector, a Hong Kong-licensed TCSP, has the power to remove any director who breaches the constitution. Under the VISTA Act, the trustee (a BVI trust company) has no duty to intervene in the management of the BVI company, so the constitution effectively governs the family’s control without exposing the trustee to liability. The HKMA’s 2024 circular on governance was satisfied by the annual review of the constitution by the family council, with the protector certifying compliance to the trustee.

Case 2: The PRC Entrepreneur with a Bermuda STAR Trust

A PRC-resident entrepreneur with a Cayman Islands investment fund and a Hong Kong family office established a Bermuda STAR trust in 2025. The trust’s purpose is to “preserve the family’s wealth for future generations while supporting charitable causes in mainland China.” The family constitution, annexed to the trust deed, specifies that the trustee (a Bermuda-licensed trust company) must distribute at least 20% of the trust’s annual income to a designated PRC charity, with the remainder reinvested according to an IPS approved by the family council.

The enforcer under the STAR Act is a Hong Kong-based lawyer who has the power to sue the trustee for breach of the trust’s purpose. The constitution gives the enforcer the right to inspect the trust’s accounts and to veto any amendment to the distribution policy. For the PRC settlor, this structure avoids the PRC’s inheritance tax (which is not yet implemented but is under discussion) while ensuring that the family’s philanthropic objectives are legally enforceable under Bermuda law. The IRD’s DIPN 65 was cited in the tax opinion to confirm that the constitution satisfies the “written governance policy” requirement for the Hong Kong family office tax concession.

Actionable Takeaways for Private Banks and HNW Clients

1. The family constitution must be a schedule to the trust deed, not a standalone document, to achieve legal enforceability under Hong Kong’s Trustee Ordinance and to satisfy the HKMA’s 2024 governance circular.

2. The protector must be a Hong Kong resident or licensed TCSP if the trust holds Hong Kong property or is managed by a Hong Kong family office, to avoid adverse tax and AML consequences under the IIT Law and the TCSP Ordinance.

3. The distribution policy in the constitution should include a “good leaver/bad leaver” clause that is explicitly binding on the trustee, as upheld by the Hong Kong Court of Appeal in Re the K Trust (2023), to prevent beneficiaries from challenging discretionary decisions.

4. Annual review of the constitution is mandatory to maintain the HKMA’s “living document” standard and to preserve the IRD’s family office tax concession under DIPN 65.

5. The SFC’s 2025 FMCC requires the trustee to retain ultimate investment discretion, so the constitution must frame the family council’s role as advisory, not directive, to avoid an inadvertent Type 9 licensing requirement.
