How to Make a Will in Hong Kong: Legal Requirements for a Valid Will Under the Wills Ordinance

Hong Kong’s High Court recorded 27,290 probate applications in 2024, a 3.2% increase from the 26,450 filed in 2023, according to the Judiciary’s annual statistics. This uptick, driven by an ageing population and the post-pandemic repatriation of assets by families reviewing cross-border succession plans, underscores a persistent gap: the Wills Ordinance (Cap. 30) has remained unchanged since its 1970 enactment, yet the demographic and financial complexity of estates has transformed. For the 50+ demographic in Hong Kong—where median household net worth stood at HKD 8.03 million in the 2021 Population Census—intestacy (dying without a will) subjects assets to the Intestates’ Estates Ordinance (Cap. 73), which distributes the estate in fixed shares that may not reflect family intentions. The 2024 Land Registry data showing 7.2% of residential property transactions involved deceased owners further highlights the risk: without a valid will, property can be frozen for months or years. This article examines the precise statutory requirements for a valid will under Cap. 30, the mechanics of execution, revocation, and common pitfalls that render a will void, providing a technical framework for estate planning in Hong Kong.

Statutory Requirements Under the Wills Ordinance (Cap. 30)

The Wills Ordinance, enacted in 1970 and last amended in 1991, sets out the formalities for a valid will in Hong Kong. Section 5(1) of Cap. 30 stipulates that no will is valid unless it is in writing, signed by the testator or by some other person in their presence and by their direction, and the signature is made or acknowledged by the testator in the presence of two or more witnesses present at the same time. These witnesses must then attest and sign the will in the presence of the testator, but not necessarily in each other’s presence.

Writing and Signature Requirements

The will must be in writing—handwritten, typed, or printed—on any material. Section 5(2) clarifies that the testator’s signature must be at the foot or end of the will. The Court of Appeal in Re Estate of Fuld (Deceased) [1965] P 405, though an English authority, is cited in Hong Kong to confirm that the signature need not be a full legal name; initials or a mark (e.g., a thumbprint) suffice if made with testamentary intent. However, the signature must be made with the intention of executing the will. A signature placed elsewhere, such as in the margin or on an attached schedule, may be invalid unless it can be shown the testator intended it to form part of the will.

Witnessing Protocol

Two witnesses must be present simultaneously when the testator signs or acknowledges their signature. Each witness must then sign the will in the testator’s presence, though they need not sign in each other’s presence. Section 5(3) disqualifies a beneficiary or their spouse from being a witness: if a beneficiary witnesses the will, the gift to that beneficiary is void, though the will itself remains valid. The High Court in Re Bravda [1968] 1 WLR 479 confirmed this principle, which Hong Kong courts follow. Witnesses should be independent, over 18, and of sound mind. A common error is using a spouse as a witness for the other spouse’s will—this does not invalidate the will, but the spouse’s gift under the will is void, a point frequently overlooked by lay testators.

Testamentary Capacity

Beyond formalities, the testator must have testamentary capacity at the time of execution, as established in Banks v Goodfellow (1870) LR 5 QB 549. The testator must understand the nature of making a will, the extent of their property, the moral claims of potential beneficiaries, and the effect of the will’s provisions. The High Court in Re Estate of Ho Mei Ling [2021] HKCFI 1234 applied this test, noting that dementia or mental illness at execution renders a will void. Medical evidence, ideally from a geriatrician, is advisable for testators over 70 or those with cognitive decline. The Mental Health Ordinance (Cap. 136) provides for statutory wills for persons lacking capacity, but these require Court approval, a costly and time-consuming process.

Execution Mechanics and Common Pitfalls

The execution ceremony—the physical act of signing and witnessing—is the most frequent source of will challenges. The High Court in Re Estate of Chan Wai Keung [2019] HKCFI 2018 invalidated a will because the testator signed in the presence of only one witness, who then signed alone. The second witness signed later, outside the testator’s presence, violating Section 5(1).

The Execution Ceremony

All parties must be physically present in the same room at the same time. The testator signs first, then each witness signs. The witnesses must see the testator sign or acknowledge their signature; they need not see the will’s contents. The testator should sign at the end of the will, after the text. If the will has multiple pages, the testator should initial each page or sign at the bottom of each page to prevent substitution. The High Court in Re Estate of Li Kwok Hung [2022] HKCFI 3456 upheld a will where the testator signed on the last page only, but the court noted the risk of page substitution if pages are not initialled.

Common Errors

Three errors account for over 60% of probate challenges, per the Law Society of Hong Kong’s 2023 guidance note. First, using a beneficiary as a witness: the gift to that beneficiary is void under Section 5(3). Second, signing before both witnesses are present: if the testator signs, then a witness enters the room, the signature is not made in the presence of two witnesses simultaneously. Third, failing to date the will: while not a statutory requirement under Cap. 30, an undated will creates ambiguity about whether a later will or codicil revokes it. The High Court in Re Estate of Wong Siu Yin [2020] HKCFI 4567 held that an undated will could still be valid if the date could be established by extrinsic evidence, but this adds litigation risk.

Codicils Versus New Wills

A codicil—a supplementary document amending a will—must meet the same execution formalities as the original will under Section 5(1). The High Court in Re Estate of Ng Kwok Wai [2023] HKCFI 789 confirmed that a codicil must be executed with two witnesses. A common error is writing amendments directly on the original will after execution; this constitutes a revocation or alteration that is invalid unless executed as a new will. Section 16 of Cap. 30 provides that any alteration made after execution is ineffective unless executed with the same formalities. The safer approach is a new will that expressly revokes all prior wills.

Revocation, Alteration, and Preservation

A will can be revoked by marriage, a later will, destruction with intent, or a written declaration executed with will formalities. Understanding revocation is critical for testators who update estate plans without formally revoking earlier documents.

Automatic Revocation by Marriage

Section 14 of Cap. 30 provides that marriage automatically revokes a will, unless the will expressly states it is made in contemplation of marriage to a specific person. The High Court in Re Estate of Tsang Yuen Mei [2021] HKCFI 2345 applied this: a testator who married after executing a will died intestate (i.e., without a valid will) because the will was revoked by marriage. For couples in Hong Kong, where 47.8% of marriages in 2023 involved at least one party aged 50 or over (Census and Statistics Department, 2024), this is a frequent trap. A will should include a clause stating “made in contemplation of my marriage to [name]” to survive the marriage.

Physical Destruction

Section 15 of Cap. 30 allows revocation by burning, tearing, or otherwise destroying the will with the intention of revoking it. The destruction must be by the testator or by another person in their presence and by their direction. The High Court in Re Estate of Lam Kwok Fai [2022] HKCFI 4568 held that partial tearing of a will, without clear intent, did not constitute revocation. A testator who writes “cancelled” across the will but does not destroy it has not revoked it; the will remains valid. The safest method is a new will with an express revocation clause.

Preservation and the Original Will

The original will must be preserved. The Probate Registry requires the original for grant of probate; a photocopy is insufficient. The High Court in Re Estate of Fung Wai Ling [2023] HKCFI 1234 refused probate where the original will was lost and only a copy existed, unless the court was satisfied the will was not revoked by destruction. The testator should store the original will with a solicitor, at a bank safe deposit box, or with the High Court’s will depository service (the Probate Registry accepts wills for safekeeping for a nominal fee). The testator should inform the executor of the will’s location.

Cross-Border Considerations and 2025 Regulatory Context

Hong Kong’s position as a financial hub means many testators hold assets in multiple jurisdictions. The Wills Ordinance applies only to immovable property in Hong Kong; for assets in other jurisdictions, local succession laws apply. The 2024 amendments to the PRC Succession Law (effective 1 January 2025) introduced a new statutory will form for PRC citizens, which may affect Hong Kong residents with PRC property.

PRC Succession Law Amendments (2025)

The PRC’s amended Succession Law, effective 1 January 2025, now recognises holographic (handwritten) wills as a standard form, provided they are entirely handwritten, dated, and signed by the testator. This is a departure from the Hong Kong requirement for two witnesses. For a Hong Kong resident with PRC property, a will executed under Cap. 30 may not automatically satisfy PRC formalities for immovable property in the PRC. The High Court in Re Estate of Hui Kwok Ming [2024] HKCFI 789 applied the lex situs rule: the validity of a will concerning immovable property is determined by the law of the jurisdiction where the property is located. A Hong Kong will for PRC property should be executed in compliance with both Cap. 30 and the PRC Succession Law, or a separate PRC will should be prepared.

US and UK Assets

For US assets, the Internal Revenue Code imposes an estate tax on non-resident aliens with US situs assets exceeding USD 60,000 (2024 threshold). A Hong Kong will that does not address US estate tax planning may expose beneficiaries to a 40% tax rate on US assets. Similarly, UK inheritance tax applies to UK assets at 40% above the GBP 325,000 nil-rate band. The testator should consider separate wills for each jurisdiction, or a single will with specific clauses addressing each jurisdiction’s tax and succession rules. The Law Society of Hong Kong’s 2023 Practice Direction on Multi-Jurisdictional Wills recommends a “situs will” for each jurisdiction, with a master will governing Hong Kong assets.

2025 Regulatory Changes in Hong Kong

The Hong Kong government’s 2024 Policy Address proposed amendments to the Probate and Administration Ordinance (Cap. 10) to streamline the probate process for small estates (under HKD 1 million). While not yet enacted as of February 2025, the proposal would allow a simplified application without a formal grant of probate for estates under HKD 500,000, reducing time and cost. This does not change the will validity requirements under Cap. 30, but it affects the distribution timeline for smaller estates.

Actionable Takeaways

1. Execute your will with two independent witnesses present simultaneously, ensuring neither witness is a beneficiary or the spouse of a beneficiary, to avoid void gifts under Section 5(3) of Cap. 30.

2. Include a contemplation of marriage clause if you plan to marry after executing the will, as Section 14 automatically revokes the will upon marriage unless this clause is present.

3. Store the original will with a solicitor or the High Court’s will depository, and inform your executor of its location, as the Probate Registry requires the original for grant of probate and will reject photocopies.

4. For PRC property, execute a separate PRC-compliant will or ensure your Hong Kong will meets both Cap. 30 and the 2025 PRC Succession Law’s formalities, given the lex situs rule applied in Re Hui Kwok Ming [2024].

5. Review your will every three years or after any major life event (marriage, divorce, birth of a child, acquisition of foreign property) to ensure it remains valid and reflects your current estate planning intentions.
