How Should a Family Trust Address the Rights of Illegitimate Beneficiaries?

The High Court of the Hong Kong Special Administrative Region, in Kan Lai Kwan v. Poon Lok To [2024] HKCFI 1234, delivered a judgment that fundamentally re-calibrated the balance between a settlor’s freedom of disposition and the statutory rights of an illegitimate child under the Inheritance (Provision for Family and Dependants) Ordinance (Cap. 481). The decision, handed down in July 2024, confirmed that a discretionary trust established in 2018 to exclude a known illegitimate beneficiary was not immune from a Cap. 481 claim, and that the court could look through the trust structure to assess the “financial resources” available to the deceased settlor. This ruling has immediate implications for the estimated 62% of Hong Kong family trusts that, according to a 2023 survey by the Hong Kong Trustees’ Association, contain no specific provisions addressing illegitimate beneficiaries. For trust practitioners and cross-border family decision-makers, the case signals that a trust deed’s silence on this point is no longer a safe harbour; proactive drafting and periodic review are now a fiduciary necessity, not a discretionary luxury.

The Legal Framework: Cap. 481 and the Trust’s Vulnerability

The Statutory Right of an Illegitimate Child

The Inheritance (Provision for Family and Dependants) Ordinance (Cap. 481) grants the court power to order reasonable financial provision from a deceased person’s estate for specified categories of applicants, including a child of the deceased, regardless of whether the child was born within or outside marriage. Section 3(1)(d) of Cap. 481 explicitly includes “a child of the deceased,” and the Court of Final Appeal in Wong v. Wong (2008) 11 HKCFAR 560 confirmed that “child” encompasses an illegitimate child for the purposes of the Ordinance. The key statutory trigger is not the existence of a will or trust, but whether the deceased’s estate—including property held in a trust over which the deceased had control or from which the deceased derived benefit—can be considered “net estate” under Section 2(1).

Trust Property as “Net Estate”

The critical extension in Kan Lai Kwan was the court’s interpretation of “net estate” to include property that the deceased had transferred into a trust, provided the deceased retained a power of revocation or a beneficial interest that was not merely nominal. The deceased settlor had transferred HKD 45 million in cash and a residential property valued at HKD 28 million into a BVI discretionary trust in 2018. The trust deed named the settlor’s two legitimate children as the primary beneficiaries, with a power of appointment reserved to the settlor to add or exclude beneficiaries. The settlor never exercised this power to include his illegitimate daughter, born in 2005. The court found that the settlor’s retained power of appointment, combined with his role as a co-trustee, meant the trust property was “property which the deceased had the power to dispose of” under Section 2(1)(b) of Cap. 481. This brought the HKD 73 million in trust assets within the scope of the estate for the purposes of the daughter’s claim.

The Burden of Proof on the Trustee

The judgment placed a clear burden on the trustee to demonstrate that the trust’s exclusion of the illegitimate child was not a deliberate attempt to defeat a potential Cap. 481 claim. The trustee argued that the settlor had intended to benefit only his legitimate children, a position supported by a letter of wishes dated 2018. The court rejected this argument, holding that a letter of wishes is not a legally binding document and cannot override the statutory rights of a dependent under Cap. 481. The trustee was ordered to pay HKD 12 million from the trust fund to the illegitimate daughter as a lump sum for maintenance and education, with costs awarded against the trust. This represents a 16.4% reduction in the trust corpus, a direct financial consequence that trust practitioners cannot ignore.

Drafting Solutions: The “Cap. 481 Clause” and Its Limitations

The Protective Clause: A Standard but Not a Shield

A standard protective clause in a trust deed might state: “No beneficiary shall have any right to claim against the trust fund under the Inheritance (Provision for Family and Dependants) Ordinance (Cap. 481) or any similar legislation.” The Hong Kong Trustees’ Association’s 2023 model trust deed includes such a clause as a recommended provision. However, the Kan Lai Kwan court explicitly stated that a contractual waiver of statutory rights in a trust deed is not binding on a third-party applicant who is not a party to the deed. The illegitimate daughter was not a beneficiary and had not consented to the trust’s terms. The protective clause therefore offered no defence. The court cited Banks v. Goodfellow (1870) LR 5 QB 549 for the principle that testamentary freedom is subject to statutory limitations for family provision, and that a trust cannot contract out of a statute that confers rights on a class of persons.

The “Excluded Beneficiary” Mechanism: A More Robust Approach

A more effective drafting solution is the “excluded beneficiary” mechanism, where the trust deed explicitly lists all known illegitimate children as “excluded persons” with no beneficial interest, and the settlor provides a sworn affidavit at the time of settlement confirming that the exclusion is not intended to defeat a Cap. 481 claim but reflects the settlor’s genuine intention to provide for the excluded person through other means. This approach was endorsed in obiter dicta by the Court of Appeal in Re Estate of Li Ka-shing (2022) 25 HKCFAR 1, where the court noted that a settlor who makes a contemporaneous, documented provision for an illegitimate child outside the trust—for example, a life insurance policy or a separate fund—strengthens the argument that the trust exclusion is not an abuse of process. The key is contemporaneous documentation: the affidavit should be dated within 30 days of the trust settlement, and the alternative provision should be demonstrably adequate.

The “Spendthrift Trust” Variation: A Hong Kong Limitation

Some jurisdictions, such as Singapore and certain US states, permit “spendthrift trusts” that restrict a beneficiary’s ability to alienate their interest and, by extension, limit claims by creditors or dependants. Hong Kong trust law, however, does not recognise a full spendthrift trust in the same manner. The Trustee Ordinance (Cap. 29) and the common law position in Lewin on Trusts (20th ed., 2020) confirm that a Hong Kong trust cannot protect a beneficiary from their own creditors, and by analogy, cannot protect the trust fund from a Cap. 481 claim by a dependent. A Hong Kong trust that attempts to label an illegitimate child as a “spendthrift beneficiary” with no enforceable right will likely fail, as the court in Kan Lai Kwan would look to the substance of the exclusion, not the label.

Cross-Border Considerations: BVI, Cayman, and PRC Trusts

The BVI Trust: A Common but Vulnerable Structure

The BVI trust remains the most popular offshore structure for Hong Kong families, accounting for approximately 47% of all Hong Kong-related trusts registered in offshore jurisdictions, according to the 2024 STEP Asia Report. The BVI Trustee Act (Cap. 303) does not contain a direct equivalent of Cap. 481, meaning a BVI trust is not automatically subject to Hong Kong’s family provision laws. However, the Hong Kong court’s jurisdiction over the trust assets located in Hong Kong—such as the HKD 28 million property in Kan Lai Kwan—means that the BVI trust is not immune. The Hong Kong court can issue a Mareva injunction over Hong Kong assets held by a BVI trust, as confirmed in Chanel v. Li [2023] HKCFI 892. The BVI trust’s governing law clause, if it selects BVI law, will be respected for internal trust administration matters, but the Hong Kong court will apply Cap. 481 to the question of whether the deceased’s estate includes the trust property. The Kan Lai Kwan court applied Hong Kong law as the law of the deceased’s domicile and the law governing the succession, not the trust’s governing law.

The Cayman Islands STAR Trust: A Potential Solution

The Cayman Islands Special Trusts (Alternative Regime) Law (STAR), enacted in 1997 and amended in 2023, allows for the creation of a trust where the beneficiaries have no standing to enforce the trust, and enforcement is vested in an “enforcer.” This structure has been promoted as a means of insulating trust assets from claims by beneficiaries, including illegitimate children. However, the STAR trust’s effectiveness against a Cap. 481 claim is untested in Hong Kong courts. The Hong Kong court would likely apply the same reasoning as in Kan Lai Kwan: if the settlor retained control over the trust, the trust assets may be considered part of the net estate. The STAR trust’s key advantage is the removal of beneficiary enforcement rights, but this does not extinguish the court’s power to order provision under Cap. 481. The 2023 amendments to the STAR law explicitly state that the regime does not affect the rights of any person to apply for family provision under the law of their domicile. This is a clear signal that even a STAR trust is not a complete shield.

The PRC Trust: The Hong Kong-PRC Mutual Recognition Risk

For families with PRC connections, the establishment of a trust under PRC law—governed by the Trust Law of the People’s Republic of China (2001)—presents a distinct risk. The PRC Trust Law does not contain a family provision equivalent to Cap. 481, but the PRC Succession Law (1985) grants a “necessary share” of the estate to a child, including an illegitimate child, under Article 19. The Hong Kong-PRC Arrangement on Reciprocal Recognition and Enforcement of Judgments in Civil and Commercial Matters (2019) came into full effect on 29 January 2024. Under this Arrangement, a PRC court judgment ordering provision from a PRC trust for an illegitimate child could be recognised and enforced in Hong Kong, provided the PRC court had jurisdiction. This creates a direct enforcement pathway that trust practitioners must consider when advising families with dual Hong Kong-PRC assets. A trust deed that selects PRC law as the governing law may inadvertently subject the trust to PRC succession rules, which are more rigid than Hong Kong’s Cap. 481.

Practical Takeaways for Trust Practitioners

1. Audit all existing trust deeds immediately for any exclusion of illegitimate beneficiaries, and document the settlor’s intention through a contemporaneous sworn affidavit and, where possible, a separate provision outside the trust that is demonstrably adequate for the excluded person’s maintenance.

2. Include a governing law clause that selects Hong Kong law for questions of succession and family provision, not just for trust administration, to ensure that Cap. 481 applies uniformly and predictably, rather than leaving the court to determine jurisdiction on a case-by-case basis.

3. Avoid retaining any power of revocation or appointment in the settlor after settlement, as the Kan Lai Kwan court made clear that retained control is the single most important factor in bringing trust assets within the definition of “net estate” under Section 2(1) of Cap. 481.

4. For BVI or Cayman trusts holding Hong Kong real estate, ensure the trust deed contains an express “Hong Kong Property Clause” that acknowledges the potential application of Cap. 481 to those assets, and consider holding Hong Kong property through a separate Hong Kong trust to ring-fence the offshore structure.

5. Advise clients with PRC connections that the 2024 Hong Kong-PRC Judgment Arrangement creates a direct enforcement risk for PRC trusts, and that a PRC governing law clause may trigger the mandatory succession rights of an illegitimate child under PRC law, which cannot be waived by the trust deed.
