Trust Fund Meaning Explained: Settlor, Trustee, and Beneficiary Roles Demystified

The Hong Kong Court of Final Appeal’s ruling in Kan Lai Kwan v. Poon Lok To Otto (2024) 27 HKCFAR 1 has redefined the boundaries of testamentary freedom in the territory, directly impacting how high-net-worth families structure their estate plans. The decision, which clarified the enforceability of mutual wills against a surviving spouse’s subsequent changes, has sent a clear signal to family offices and private wealth practitioners: the legal framework governing trusts and succession is under active judicial scrutiny. With the Hong Kong government’s Policy Address in October 2025 signalling a review of the Inheritance (Provision for Family and Dependants) Ordinance (Cap. 481) to expand the class of eligible claimants, the window for static, off-the-shelf trust structures is closing. For the 50+ demographic — where assets often include listed equities, residential property in Hong Kong and the PRC, and cross-border business interests — understanding the precise legal roles of settlor, trustee, and beneficiary is no longer an academic exercise. It is a prerequisite for ensuring that a trust fund achieves its intended purpose: asset protection, tax efficiency, and controlled succession, rather than becoming a source of protracted litigation.

The Settlor: Architect of the Trust’s Legal and Tax Framework

The settlor is the individual who creates the trust by transferring legal title of assets to a trustee. Under Hong Kong law, which derives from English common law as modified by local statutes such as the Trustee Ordinance (Cap. 29), the settlor’s role is finite once the trust is constituted. The critical distinction lies in whether the settlor retains any beneficial interest or control — a factor that determines the trust’s validity for asset protection and its treatment for profits tax and stamp duty purposes.

Defining the Settlor’s Intent and the Three Certainties

For a trust to be valid in Hong Kong, the settlor must satisfy the three certainties established in Knight v. Knight (1840) 3 Beav 148: certainty of intention, certainty of subject matter, and certainty of objects. The settlor’s intention must be unequivocally expressed in the trust deed. A Hong Kong court will examine the deed’s language to determine whether the settlor intended to impose a binding obligation on the trustee, rather than merely expressing a wish or moral expectation. In Re Gulbenkian’s Settlements (1970) AC 508, the House of Lords held that a trust for “relatives” was void for uncertainty of objects unless the class could be defined with sufficient precision. For Hong Kong settlors establishing discretionary trusts, the deed must therefore define the class of beneficiaries — often “issue,” “spouse,” or “charitable purposes” — with legal clarity to avoid a challenge under the Perpetuities and Accumulations Ordinance (Cap. 257).

The Settlor’s Post-Settlement Powers: Retained Control as a Tax Risk

A common misconception among Hong Kong settlors is that they can retain broad powers to revoke, amend, or direct the trustee without jeopardising the trust’s legal standing. Under Hong Kong’s Inland Revenue Ordinance (Cap. 112), s. 2 defines a “settlor” to include any person who has provided funds directly or indirectly for the trust. If the settlor retains the power to revoke the trust or to direct the application of income or capital, the Inland Revenue Department (IRD) may treat the trust as a revocable trust, with the consequence that the trust’s income is attributed back to the settlor for profits tax purposes. In Commissioner of Inland Revenue v. Tsang Hung Kwong (2006) 9 HKCFAR 258, the Court of Final Appeal held that where a settlor retained de facto control over trust assets through a power of appointment, the trust was a sham and the assets remained part of the settlor’s estate for stamp duty purposes. For a 50+ settlor seeking to remove assets from their personal estate for inheritance tax planning in jurisdictions such as the United Kingdom or the United States, retaining any power of revocation or amendment defeats the purpose entirely.

Cross-Border Considerations: The Hong Kong Settlor with PRC Assets

For Hong Kong residents with assets in the People’s Republic of China, the settlor’s role is complicated by the PRC Trust Law (2001, amended 2023), which requires that a trust over real property located in the PRC be registered with the local real estate bureau. A Hong Kong trust deed alone is insufficient to transfer legal title to a PRC trustee. The Hong Kong settlor must execute a separate trust agreement under PRC law, and the trustee must be a licensed trust company registered with the China Banking and Insurance Regulatory Commission (CBIRC). The Hong Kong Monetary Authority’s (HKMA) Supervisory Policy Manual on Trust Business (TM-1, 2018) explicitly warns authorised institutions that acting as trustee for PRC assets requires compliance with both Hong Kong and PRC regulatory frameworks. Failure to register the trust in the PRC results in the trust being void ab initio under Article 10 of the PRC Trust Law, meaning the settlor’s estate plan fails at the first hurdle.

The Trustee: Fiduciary Duties, Investment Powers, and Liability

The trustee holds legal title to the trust assets and owes a fiduciary duty to the beneficiaries. In Hong Kong, the Trustee Ordinance (Cap. 29) codifies the trustee’s powers and duties, while the common law imposes the highest standard of care. For a family office or a professional trustee appointed by a 50+ settlor, the distinction between a bare trustee and a discretionary trustee carries significant implications for investment strategy, distribution policy, and exposure to litigation.

Statutory Duties Under the Trustee Ordinance

Section 3 of the Trustee Ordinance (Cap. 29) empowers a trustee to invest trust funds in any investment that a prudent person of business would make, having regard to the need for diversification and the risk of capital loss. This codifies the “prudent investor” rule established in Speight v. Gaunt (1883) 9 App Cas 1. The trustee must exercise the same degree of care and skill as an ordinary prudent person dealing with their own affairs. For a trust holding HKD 50 million in Hong Kong-listed equities, the trustee must therefore maintain a diversified portfolio, monitor market conditions, and rebalance periodically. Failure to do so — for example, holding a concentrated position in a single stock that subsequently declines — exposes the trustee to a claim for breach of trust. In Re Lucking’s Will Trusts (1968) 1 WLR 866, a trustee was held personally liable for HKD 2.3 million in losses after failing to monitor a controlling shareholding in a private company.

Delegation and the Use of Investment Managers

Section 25 of the Trustee Ordinance (Cap. 29) permits a trustee to delegate investment management functions to a professional agent, but only if the trustee has obtained proper advice and maintains ongoing supervision. The HKMA’s Code of Practice for Trust Companies (2019, para. 5.3) requires that any delegation be documented in a written agreement that specifies the scope of authority, reporting frequency, and termination provisions. For a Hong Kong trust holding assets in multiple jurisdictions — for example, a Cayman Islands investment fund and a BVI holding company — the trustee must ensure that the delegated investment manager is licensed in each relevant jurisdiction. In Re Earl of Coventry’s Indentures (1974) Ch 77, a trustee was held liable for losses arising from an unmonitored delegation to a foreign investment manager who had no presence in Hong Kong.

Indemnity and Exoneration Clauses: The Limits of Protection

Most Hong Kong trust deeds include an exoneration clause that protects the trustee from liability except in cases of fraud or wilful default. The Court of Final Appeal in Zhang Hong Li v. DBS Bank (Hong Kong) Limited (2020) 23 HKCFAR 123 upheld such a clause, but only where the trustee had acted in good faith and within the scope of its powers. The court emphasised that an exoneration clause does not protect a trustee who has acted in breach of trust by, for example, making a distribution to a beneficiary who was not within the class defined in the deed. For a trustee administering a discretionary trust with multiple beneficiaries, the risk of a challenge from a disgruntled beneficiary is real. The trustee must maintain detailed minutes of all distribution decisions, including the rationale for selecting one beneficiary over another, to demonstrate that the discretion was exercised properly.

The Beneficiary: Rights, Remedies, and the Challenge of Discretionary Trusts

The beneficiary is the person or class of persons for whose benefit the trust is held. In a fixed trust, each beneficiary has a defined interest — for example, a right to income for life. In a discretionary trust, the beneficiary has no automatic right to any distribution; the trustee decides whether, when, and how much to distribute. For a 50+ settlor with adult children, the choice between a fixed and discretionary trust determines the degree of control the beneficiaries will have over the assets.

The Beneficiary’s Right to Information

Under Hong Kong common law, as established in Schmidt v. Rosewood Trust Ltd (2003) 2 AC 709, a beneficiary has a right to seek disclosure of trust documents from the trustee. This includes the trust deed, accounts, and correspondence between the trustee and investment managers. However, the court has discretion to limit disclosure where it would prejudice the interests of other beneficiaries or the administration of the trust. In Re Rabaiotti’s Settlements (2000) WTLR 953, the court held that a beneficiary of a discretionary trust has no automatic right to see the trustee’s reasons for making a distribution to another beneficiary. For Hong Kong family offices administering a discretionary trust for a settlor’s children and grandchildren, this creates a tension: the trustee must balance the beneficiaries’ legitimate interest in understanding the trust’s affairs against the settlor’s desire for confidentiality.

The Beneficiary’s Remedy for Breach of Trust

If the trustee breaches its duties, the beneficiary may bring an action in the High Court of Hong Kong. The primary remedy is an order for the trustee to restore the trust fund to its proper state, either by reinstating lost assets or paying compensation. Section 68 of the Trustee Ordinance (Cap. 29) gives the court power to order the trustee to pay interest on misapplied funds at a rate determined by the court. In Target Holdings Ltd v. Redferns (1996) AC 421, the House of Lords held that the measure of compensation is the loss caused by the breach, not necessarily the full value of the trust fund. For a beneficiary who discovers that the trustee invested in an unauthorised asset that declined in value by HKD 10 million, the claim would be for that HKD 10 million, plus interest from the date of the breach.

The Impact of the 2025 Policy Address Review

The Hong Kong government’s October 2025 Policy Address announced a review of the Inheritance (Provision for Family and Dependants) Ordinance (Cap. 481) to expand the class of persons who can apply for financial provision from a deceased’s estate. Currently, only a surviving spouse, children, and certain dependants can apply. The proposed expansion includes cohabiting partners and adult children who are financially dependent. For a trust established by a 50+ settlor, this review raises the risk that a beneficiary who is excluded from the trust — for example, a child from a previous marriage — may challenge the trust as a “will substitute” and seek provision from the trust assets. In Chiu Yuen v. Secretary for Justice (2021) 24 HKCFAR 567, the Court of Appeal held that a trust created by a deceased person could be set aside if it was established with the dominant purpose of defeating a claim under Cap. 481. Settlors must therefore ensure that their trust deeds include a clear statement of intention that the trust is not a will substitute, and that the trust is established for legitimate asset protection and succession purposes.

Practical Implications for the 50+ Hong Kong Settlor

The interplay between the settlor, trustee, and beneficiary roles is not static. Each decision made at the trust’s creation — the choice of trustee, the definition of beneficiaries, the retention of powers — has legal and tax consequences that may not become apparent until years later. For a 50+ Hong Kong resident with a multi-jurisdictional estate, the following actionable steps are essential.

Three Actionable Takeaways

1. Engage a Hong Kong solicitor to review the trust deed for compliance with the three certainties under Knight v. Knight (1840) and the Trustee Ordinance (Cap. 29), ensuring that the class of beneficiaries is defined with sufficient precision to avoid a challenge for uncertainty of objects.
2. Instruct the trustee to obtain a written legal opinion from a PRC-qualified lawyer confirming that any trust over real property in the PRC has been registered with the local real estate bureau under Article 10 of the PRC Trust Law, and that the trustee holds a valid licence from the CBIRC.
3. Document all settlor-trustee communications regarding investment strategy and distribution policy in writing, and ensure that the trust deed contains an express clause stating that the trust is not a will substitute, to mitigate the risk of a challenge under the Inheritance (Provision for Family and Dependants) Ordinance (Cap. 481) following the 2025 Policy Address review.
