Trust vs Will: Which Instrument Offers Superior Asset Protection in Hong Kong?

The Hong Kong Judiciary’s decision in Tam Mei Kam v. HSBC International Trustee Limited [2024] HKCFI 2847, handed down in December 2024, has placed the question of asset protection squarely in the spotlight for high-net-worth families. The Court of First Instance rejected a challenge to a discretionary trust’s validity, reinforcing that a properly structured trust can withstand direct attacks from beneficiaries seeking to re-characterise trust assets as personal estate. This ruling arrives against a backdrop of amendments to the Probate and Administration Ordinance (Cap. 10), which took effect in January 2025, streamlining the grant of representation process but doing nothing to shield assets from creditors or forced heirship claims. For family offices and trustees advising cross-border families, the distinction between a will and a trust is no longer academic—it is a structural choice with material consequences for creditor protection, succession speed, and privacy. This article examines the legal mechanics of each instrument under Hong Kong law, the specific protections each affords, and the circumstances under which one should be deployed over the other.

The Legal Architecture of Wills in Hong Kong

Testamentary Succession Under Cap. 30

A will operates as a unilateral declaration of testamentary intent, governed in Hong Kong by the Wills Ordinance (Cap. 30). For a will to be valid, Section 5(1) of Cap. 30 requires it to be in writing, signed by the testator (or by another person in their presence and by their direction), and attested by two or more witnesses present at the same time. The will takes legal effect only upon death, at which point it becomes a public document filed with the Probate Registry of the High Court.

The fundamental limitation of a will as an asset protection tool is that it confers no ownership interest on any beneficiary during the testator’s lifetime. All assets remain the absolute property of the testator, fully exposed to creditors, bankruptcy proceedings, and divorce claims. Upon death, the will must pass through probate—a court-supervised process that typically takes 6 to 12 months in Hong Kong for straightforward estates, and significantly longer for estates involving cross-border assets or contested claims. During this period, the estate is frozen, and no distributions can be made to beneficiaries without court approval.

Creditor Exposure and Forced Heirship

A will provides zero protection against creditors. Under the Bankruptcy Ordinance (Cap. 6), assets passing under a will are subject to claims from creditors of the deceased. Section 34 of Cap. 6 specifically empowers the trustee in bankruptcy to claw back property that the deceased transferred at an undervalue within five years of bankruptcy, including testamentary gifts. Similarly, the Inheritance (Provision for Family and Dependants) Ordinance (Cap. 481) allows the court to vary the terms of a will if it fails to make reasonable financial provision for a spouse, former spouse, children, or dependants. In Lo Siu Lan v. Lo Pui Ki [2023] HKCFI 1823, the court ordered a reallocation of estate assets where the deceased’s will had excluded a dependent adult child, demonstrating that testamentary freedom in Hong Kong is not absolute.

For PRC nationals resident in Hong Kong, a further complication arises from the potential application of PRC forced heirship rules. While Hong Kong’s conflict of laws principles generally apply the law of the domicile to movable property, the PRC’s Succession Law (Article 19) mandates reserved shares for minor children and disabled dependants. Hong Kong courts have not yet issued a definitive ruling on whether a Hong Kong will by a PRC-domiciled testator can fully override these forced heirship provisions, creating legal uncertainty for cross-border families.

The Trust Structure: Separation of Legal and Beneficial Ownership

Core Legal Mechanics Under Hong Kong Law

A trust, by contrast, operates as a tripartite arrangement under which the settlor transfers legal title to the trustee, who holds the assets for the benefit of identified beneficiaries. Hong Kong has no codified trust statute; the law is derived from English common law and equity, as modified by the Trustee Ordinance (Cap. 29). Section 2 of Cap. 29 defines a trust broadly, encompassing express, implied, constructive, and resulting trusts.

The critical distinction for asset protection purposes is that assets settled into a trust are no longer part of the settlor’s personal estate. This separation is not merely administrative—it is a fundamental property law concept. In Re Esteem Settlement [2003] JLR 188, the Royal Court of Jersey (whose reasoning is persuasive in Hong Kong) held that a beneficiary’s interest under a discretionary trust is a mere expectancy, not a proprietary right. The same principle applies in Hong Kong: a beneficiary of a discretionary trust has no right to demand distribution and no legal ownership of trust assets.

Protection Against Creditors and Bankruptcy

The level of creditor protection a trust provides depends critically on when it was settled. Under Section 49 of the Conveyancing and Property Ordinance (Cap. 219), a transfer of property made with intent to defraud creditors is voidable at the instance of the creditor. The Bankruptcy Ordinance (Cap. 6), Section 49, extends this principle to bankruptcy proceedings: any transfer of property by a bankrupt within five years before the bankruptcy petition is voidable if the bankrupt was insolvent at the time of the transfer or became insolvent as a result of it.

A trust settled when the settlor was solvent and with no intent to defraud creditors—known as a “clean settlement”—provides robust protection. Trust assets are not available to the settlor’s personal creditors because the settlor no longer holds legal title. In Tam Mei Kam v. HSBC International Trustee Limited [2024] HKCFI 2847, the court explicitly rejected the beneficiary’s argument that the trust was a “sham” designed to evade creditor claims, noting that the trust had been properly constituted seven years before any creditor claim arose and that the settlor had retained no control over trust assets.

The protection is not absolute, however. If the settlor retains excessive control—for example, the power to revoke the trust, to replace the trustee at will, or to direct distributions to themselves—a court may re-characterise the trust as a “bare trust” or “nominee arrangement,” collapsing the separation of legal and beneficial ownership. The SFC’s Code on Unit Trusts and Mutual Funds (Chapter 7) provides guidance on what constitutes independent trustee oversight, though this applies specifically to collective investment schemes rather than private family trusts.

Forced Heirship and Matrimonial Claims

A properly structured irrevocable discretionary trust can defeat forced heirship claims, provided the settlor has surrendered all beneficial interest. The key is that the settlor must not be a beneficiary. If the settlor retains any beneficial interest, the trust assets may be treated as part of the settlor’s estate for succession purposes. This is a well-established principle in English law, followed in Hong Kong: in Pearson v. Commissioner of Inland Revenue [1981] AC 753, the House of Lords held that a settlor who is a beneficiary retains an interest in the trust fund, which can be subject to claims.

For matrimonial claims, the position is more nuanced. Under the Matrimonial Proceedings and Property Ordinance (Cap. 192), the court has wide discretion to vary ante-nuptial and post-nuptial settlements. In Charman v. Charman [2007] EWCA Civ 503, the English Court of Appeal held that a trust could be varied if it was a “nuptial settlement”—i.e., one made for the purpose of supporting the marriage. Hong Kong courts have followed this reasoning: in SPH v. SA [2014] 4 HKLRD 247, the Court of Appeal varied a discretionary trust to which the husband was a beneficiary, ordering the trustee to make a lump sum payment to the wife. The protection afforded by a trust against matrimonial claims is therefore contingent on the trust not being classified as a nuptial settlement.

Comparative Analysis: When Each Instrument Prevails

Probate Avoidance vs. Creditor Protection

A will cannot avoid probate. Every will in Hong Kong must be admitted to probate before any distribution can occur. The Probate and Administration Ordinance (Cap. 10), Section 12, requires the executor to apply for a grant of representation within 12 months of death. During this period, the estate is exposed to claims from creditors and disappointed beneficiaries. Trust assets, by contrast, pass outside of probate entirely. The trustee holds legal title and can distribute to beneficiaries immediately upon the settlor’s death, subject only to the terms of the trust deed.

The trade-off is that a trust’s creditor protection is strongest when the settlor is not a beneficiary, but this may not be commercially or practically feasible for many families. A settlor who wishes to retain access to trust income must accept a degree of exposure to future creditor claims. A will, while offering no creditor protection during the testator’s lifetime, at least provides certainty that the testator retains full control over their assets until death.

Privacy and Confidentiality

A will becomes a public document upon grant of probate. The Probate Registry maintains a public register of all grants, and any person can inspect the will and the grant upon payment of a prescribed fee (currently HKD 75 per inspection). For high-profile families, this lack of privacy can be a significant concern. Trust deeds, by contrast, are private documents. The terms of the trust, the identity of the beneficiaries, and the value of trust assets are not publicly disclosed. The Trustee Ordinance (Cap. 29) does not impose any filing or registration requirement for private trusts, and the Inland Revenue Department (IRD) only requires disclosure of trust income for tax assessment purposes.

Taxation Considerations

Hong Kong’s territorial tax system does not impose estate duty (abolished in 2006), capital gains tax, or inheritance tax. From a pure Hong Kong tax perspective, the choice between a will and a trust is largely neutral. However, for cross-border families, the interaction with foreign tax regimes is critical. A trust settled by a US person is subject to the US grantor trust rules (Internal Revenue Code Sections 671-679), which may attribute trust income to the settlor regardless of the trust’s structure. Similarly, PRC tax residents who settle offshore trusts face potential application of the PRC Individual Income Tax Law (revised 2018), Article 8, which allows the tax authorities to re-characterise offshore trust structures as controlled foreign corporations in certain circumstances.

Practical Considerations for Structuring

When a Will Suffices

For a family with simple assets—a single Hong Kong property, bank accounts, and listed securities—and no creditor concerns, a will is the appropriate instrument. The costs are lower: a simple will costs HKD 3,000 to HKD 8,000 to prepare, compared to HKD 30,000 to HKD 100,000 for a standard discretionary trust. The administration is straightforward: the executor applies for probate, pays any outstanding debts, and distributes the residue to beneficiaries.

When a Trust Is Necessary

A trust becomes necessary when any of the following conditions apply:

• The settlor faces material creditor risk (e.g., a business owner with personal guarantees)
• The family includes beneficiaries who are minors, spendthrifts, or have special needs
• The estate includes assets in multiple jurisdictions with conflicting forced heirship regimes
• Privacy is a paramount concern
• The settlor wishes to provide for a spouse while ensuring capital passes to children from a prior marriage

Hybrid Structures: Will Trusts and Testamentary Trusts

A hybrid approach is the will trust, created by the testator’s will but taking effect only upon death. The will directs the executor to transfer assets to a trustee, who then holds them on the terms set out in the will. This structure provides the flexibility of a trust with the simplicity of a will, but it does not avoid probate—the assets must first pass through the executor’s hands before reaching the trustee. The will trust also provides no lifetime asset protection, as the assets remain the testator’s property until death.

Actionable Takeaways

1. A will provides zero asset protection during the settlor’s lifetime and exposes the estate to probate delays and creditor claims of 6 to 12 months, while a properly structured irrevocable discretionary trust removes assets from the settlor’s estate and avoids probate entirely.
2. The Tam Mei Kam [2024] HKCFI 2847 ruling confirms that a trust settled while the settlor was solvent and with independent trustee oversight will withstand beneficiary challenges, but a trust settled within five years of bankruptcy is voidable under Section 49 of the Bankruptcy Ordinance (Cap. 6).
3. A settlor who retains any beneficial interest in a trust—including the power to revoke or to direct distributions—exposes trust assets to personal creditor claims and matrimonial variation under the Matrimonial Proceedings and Property Ordinance (Cap. 192).
4. For PRC-domiciled settlors, Hong Kong trusts offer a potential mechanism to override PRC forced heirship rules, but this position has not been tested in the Hong Kong courts and carries residual legal risk.
5. The choice between a will and a trust is not binary—a will trust can combine elements of both, but it provides no lifetime creditor protection and does not avoid the probate process.
