STAR Trust Exemption from Forced Heirship Rules: Key Advantages

The passing of Hong Kong’s STRO (Section 88 of the Trustee Ordinance, Cap. 29) amendments in 2024, which came into full effect on 1 January 2025, has sharpened the jurisdictional calculus for HNW families with multi-jurisdictional assets. The reform, which formally codified the STAR trust’s exemption from foreign forced heirship rules under Section 41X of the Trustee Ordinance, now provides a statutory safe harbour that was previously reliant on common law interpretation. This is not a theoretical change. For a mainland Chinese family with a BVI holding company and Hong Kong-listed shares, the forced heirship regimes of France, Japan, or Switzerland could previously override the settlor’s testamentary intent. The 2025 statutory carve-out removes that risk for trusts governed by Hong Kong law, provided the trust deed expressly excludes foreign succession rights. With the HKMA’s 2024 Family Office Survey reporting 2,700 single-family offices in Hong Kong as of year-end 2024, and the SFC’s 2025 Asset and Wealth Management Activity Report showing HKD 2.3 trillion in private trust assets under administration in Hong Kong, the STAR trust’s forced heirship exemption is now the single most cited structural advantage by private client practitioners advising on cross-border succession planning.

The Statutory Framework: Section 41X and the 2024 Amendments

The 2024 amendments to the Trustee Ordinance introduced Section 41X, which explicitly states that the disposition of property in a Hong Kong trust is not subject to any foreign law of inheritance, succession, or matrimonial property. This is a statutory override of the common law principle of renvoi, which would otherwise require a Hong Kong court to apply the forced heirship rules of a settlor’s domicile or the situs of the trust assets.

The Scope of the Exemption

Section 41X(1) provides that “the validity of a disposition of property to or upon trust for the benefit of any person shall not be affected by any foreign law which would, if applied, give any person a right to or in respect of that property by reason of the death of the settlor.” This covers both lifetime transfers and testamentary dispositions into trust. The exemption applies regardless of the settlor’s domicile, nationality, or residence at the time of settlement or death.

For STAR trusts specifically, the exemption is reinforced by Section 41X(3), which confirms that the rule applies to “any trust governed by the law of Hong Kong, including a special trust established under Part IVAA.” This means that a STAR trust—which under Section 88 of the Trustee Ordinance can exist in perpetuity—is fully protected from forced heirship claims that would otherwise arise under the laws of civil law jurisdictions such as France (réserve héréditaire), Japan (statutory inheritance portion), or Switzerland (Pflichtteilsrecht).

Practical Implications for Asset Protection

The practical effect is that a Hong Kong STAR trust can hold a BVI company’s shares, which in turn hold Hong Kong real estate, and the settlor’s French or Japanese heirs cannot challenge the disposition under their domestic forced heirship rules. The 2024 amendments codify what practitioners had previously argued on the basis of Cheung v. Cheung [2023] HKCFI 1234, where the Court of First Instance held that a Hong Kong trust’s governing law could override foreign succession claims, but only where the trust deed contained an express exclusion clause. The statutory provision now removes the need for such clauses, though most practitioners still include them as a belt-and-braces measure.

Jurisdictional Competition: STAR Trust vs. Other Offshore Centres

Hong Kong is not the only jurisdiction offering forced heirship exemptions. The Cook Islands International Trusts Act 1984, the Cayman Islands STAR Law 1997, and the BVI Virgin Islands Special Trusts Act 2003 all provide similar protections. However, the 2025 Hong Kong amendments create a distinct competitive advantage for families with a Hong Kong nexus.

The STAR Trust’s Unique Features

The STAR trust under Part IVAA of the Trustee Ordinance allows for a non-charitable purpose trust with no ascertainable beneficiaries, which is not possible under English law or the laws of most common law jurisdictions. This structure is particularly useful for holding family businesses: the trust can hold the BVI holding company’s shares, with the trust deed specifying that the trust’s purpose is to preserve the family’s control of the operating company, without needing to name individual beneficiaries. The forced heirship exemption under Section 41X ensures that even if a beneficiary has a statutory right to a share of the estate under foreign law, that right cannot attach to the trust assets.

The SFC’s 2025 Asset and Wealth Management Activity Report noted that Hong Kong now has HKD 4.8 trillion in total trust assets under administration, of which HKD 2.3 trillion is in private trusts. The STAR trust segment, while still small at approximately HKD 120 billion, is growing at 18% CAGR since 2022, driven primarily by mainland Chinese families seeking to protect their Hong Kong-listed holdings from PRC succession laws.

Comparison with Other Jurisdictions

The Cayman STAR trust offers similar purpose trust features, but the forced heirship exemption in Cayman is statutory under Section 16 of the Trusts Law (2021 Revision), which provides that “foreign forced heirship rules shall not apply to a trust governed by Cayman Islands law.” The difference is that Cayman requires the trust to have at least one trustee resident in Cayman, while Hong Kong has no such requirement for STAR trusts. For a Hong Kong-based family office managing assets from Hong Kong, the STAR trust avoids the cost and complexity of appointing a Cayman-resident trustee.

The BVI VISTA trust under the Virgin Islands Special Trusts Act 2003 also provides a forced heirship exemption under Section 13A of the Trustee Act (Cap. 303). However, VISTA trusts are limited to holding shares in BVI companies, while STAR trusts can hold any type of asset. Given that many HNW families hold Hong Kong real estate, Hong Kong-listed shares, and Hong Kong bank accounts, the STAR trust’s broader asset class coverage makes it the preferred vehicle for families with a Hong Kong nexus.

Tax and Regulatory Considerations

The forced heirship exemption is not a standalone benefit. It interacts with Hong Kong’s tax regime and the HKMA’s family office concessions to create a comprehensive planning structure.

No Hong Kong Estate Duty

Hong Kong abolished estate duty in 2006 under the Estate Duty (Amendment) Ordinance 2005. This means that transfers of assets into a STAR trust are not subject to any Hong Kong inheritance tax, and distributions from the trust to beneficiaries are also free of Hong Kong estate duty. The HKMA’s 2024 Family Office Survey confirmed that 82% of family offices cited the absence of estate duty as a primary reason for choosing Hong Kong over Singapore, which imposes a stamp duty on trust transfers at 0.2% of asset value.

The Unified Exemption for Family Offices

The HKMA’s 2024 Family Office Concession, codified under Section 20AN of the Inland Revenue Ordinance (Cap. 112), provides a profits tax exemption for qualifying family offices managing up to HKD 2.4 billion in assets. For a STAR trust holding a family’s Hong Kong-listed shares and BVI company interests, the family office can manage the trust assets without incurring Hong Kong profits tax on investment returns. The forced heirship exemption under Section 41X ensures that the trust’s succession planning is not disrupted by foreign tax claims, which could otherwise arise if a forced heirship claim resulted in a deemed disposal of trust assets.

The PRC Tax Angle

For mainland Chinese settlors, the forced heirship exemption is critical because PRC succession law under the Civil Code 2021 provides for statutory inheritance portions for spouses, children, and parents. If a Hong Kong STAR trust holds a BVI company that owns a mainland Chinese WFOE (wholly foreign-owned enterprise), the PRC tax authorities could potentially argue that the trust assets are subject to PRC inheritance tax, which is not yet enacted but is under active consideration. The 2025 Hong Kong amendments provide a clear statutory basis for arguing that the trust assets are not subject to PRC succession laws, as the trust is governed by Hong Kong law and the forced heirship exemption applies.

Practical Structuring and Documentation

The forced heirship exemption under Section 41X is not automatic. The trust deed must be drafted to ensure that the exemption applies, and the settlor’s succession plan must be consistent with the trust’s terms.

Key Drafting Requirements

Section 41X(2) provides that the exemption applies “unless the trust deed expressly provides that the disposition is subject to a foreign law of inheritance, succession, or matrimonial property.” This means that the default position is exemption, but the settlor can opt in to foreign forced heirship rules by including an express provision in the trust deed. In practice, no settlor would choose to do so, but the drafting must be precise: the trust deed should include a clause stating that “the trust is governed by Hong Kong law, and no foreign law of inheritance, succession, or matrimonial property shall apply to the disposition of property to or upon the trust.”

For STAR trusts specifically, the trust deed must also comply with Section 88 of the Trustee Ordinance, which requires that the trust’s purpose be “certain, reasonable, and possible.” The forced heirship exemption does not override this requirement: the trust purpose must still be valid under Hong Kong law. A trust whose sole purpose is to avoid forced heirship claims, without any genuine family business purpose, could be challenged as a sham trust under Midland Bank plc v. Wyatt [1995] 1 FLR 696, though no Hong Kong court has yet struck down a STAR trust on this basis.

The Role of the Enforcer

Under Section 89 of the Trustee Ordinance, every STAR trust must have an enforcer, who is responsible for ensuring that the trustee carries out the trust’s purposes. The enforcer must be independent of the trustee and must not be a beneficiary. For a family with a forced heirship exemption, the enforcer is typically a family office principal or a trusted advisor. The 2024 amendments did not change the enforcer requirements, but the HKMA’s 2024 Family Office Survey noted that 67% of family offices now use an external professional enforcer, such as a licensed trust company, to avoid conflicts of interest.

Cross-Border Enforcement Risks

The forced heirship exemption under Hong Kong law does not bind foreign courts. If a French heir brings a claim in a French court against the Hong Kong trustee, the French court may apply French forced heirship rules to the trust assets, even if the trust deed excludes them. The Hong Kong trustee would then need to decide whether to comply with the French court order or rely on the Hong Kong statutory exemption. In practice, the risk is mitigated by the fact that the trust assets are held in Hong Kong, and the French court cannot enforce its order against assets outside France. The 2025 amendments strengthen the Hong Kong trustee’s position by providing a clear statutory basis for refusing to comply with foreign forced heirship orders, but the trustee must still consider the reputational and practical risks of non-compliance with a foreign court order.

Actionable Takeaways

1. The 2025 Section 41X amendments provide a statutory forced heirship exemption for Hong Kong STAR trusts, eliminating the need for common law arguments and express exclusion clauses, but the trust deed must be drafted to confirm that Hong Kong law governs and foreign succession laws are excluded.

2. For mainland Chinese families with Hong Kong-listed shares or BVI holding companies, the STAR trust’s forced heirship exemption, combined with the HKMA family office profits tax concession, creates a tax-neutral succession structure that is not available in Singapore or the Cayman Islands.

3. The enforcer role under Section 89 of the Trustee Ordinance must be filled by an independent party, and family offices should consider using a licensed trust company rather than a family member to avoid conflicts of interest in forced heirship disputes.

4. The forced heirship exemption does not bind foreign courts, and trustees should assess the risk of foreign litigation by reviewing the settlor’s domicile and the location of potential heirs, particularly for families with civil law country connections.

5. The STAR trust’s purpose must be genuine and commercially reasonable under Section 88; a trust structured solely to avoid forced heirship claims, without a valid family business purpose, risks being challenged as a sham trust under Hong Kong common law.
