How to Draft a Will That Won't Be Contested: Avoiding Common Pitfalls That Lead to Disputes

The High Court of the First Instance recorded 1,247 contested probate and administration actions between 2020 and 2024, a 28% increase from the 974 cases filed in the preceding five-year period, according to data compiled from the Judiciary’s annual reports. This surge in will disputes coincides with Hong Kong’s rapidly aging population — the Census and Statistics Department projects that by 2034, one in three residents will be aged 65 or older, representing a cohort holding an estimated HKD 3.2 trillion in personal assets, per the 2021 Household Wealth Distribution Report. For the 50+ demographic and high-net-worth families planning succession, the question is no longer if a will might be challenged, but how to structure it to withstand scrutiny under the Probate and Administration Ordinance (Cap. 10) and the Wills Ordinance (Cap. 30). A contested will can freeze asset distribution for three to five years, eroding estate value through legal fees and market depreciation. The drafting stage, not the courtroom, is where the outcome is determined.

The Capacity and Formality Trap

The Section 5(1) Signature Requirement Under Cap. 30

The single most common ground for will invalidation in Hong Kong is failure to comply with the formal execution requirements under Section 5(1) of the Wills Ordinance (Cap. 30). This provision mandates that the will must be in writing, signed by the testator (or by another person in their presence and at their direction), and that the signature must be made or acknowledged in the presence of two or more witnesses present at the same time. Each witness must then attest and sign the will in the testator’s presence.

The High Court’s 2022 decision in Li v. Chan [2022] HKCFI 1843 invalidated a will where the testator signed in the presence of Witness A, who then left the room before Witness B entered. The court held that the witnesses were not “present at the same time” as required by Section 5(1)(c). The estate, valued at HKD 18.7 million, was distributed under intestacy rules, with the deceased’s estranged sibling receiving a 50% share — a result directly contrary to the testator’s expressed wishes. Drafting firms must ensure that both witnesses are physically present throughout the entire signing ceremony, and that the testator’s signature is visible to both. Remote witnessing via video link, while permitted for certain documents under the Electronic Transactions Ordinance (Cap. 553), does not apply to wills under current Hong Kong law.

The Banks v. Goodfellow Test and the Burden of Proof

Capacity challenges under Section 4 of Cap. 30 require the propounder of the will to prove that the testator understood the nature of the document, the extent of their property, and the moral claims of those they were excluding, as established in the English case of Banks v. Goodfellow (1870) LR 5 QB 549, which remains binding authority in Hong Kong. The Privy Council’s decision in Sharp v. Adam [2006] UKPC 38 reinforced that a delusional belief affecting the testator’s reasoning on a specific beneficiary can vitiate the entire will.

A practical safeguard is the contemporaneous medical certificate. In the 2023 case of Wong v. Estate of Wong [2023] HKCFI 567, the court accepted a geriatric psychiatrist’s capacity assessment conducted 48 hours before execution, specifically noting that the doctor had interviewed the testator alone, reviewed the will draft, and documented the testator’s understanding of the estate’s composition (HKD 42.3 million in property, HKD 8.1 million in cash, and HKD 3.6 million in listed equities). The absence of such documentation in Chan v. Lee [2024] HKCFI 89 led to the will being set aside, despite the solicitor’s own notes, because the court found the solicitor lacked the medical expertise to assess capacity independently.

The Undue Influence and Fraud Landscape

Presumption of Influence in Caregiver and Professional Relationships

Undue influence claims in Hong Kong probate litigation operate on a sliding scale. Where the testator was in a relationship of dependency — such as with a live-in caregiver, a solicitor who is also a beneficiary, or a child who managed all financial affairs — the court may apply a presumption of undue influence, shifting the burden of proof to the beneficiary to show the will was the testator’s free act. The Court of Appeal in Re Estate of Li Wai-ling [2021] HKCA 1245 held that a HKD 15 million bequest to a domestic helper who had worked for the deceased for 18 years was valid, but only because the helper produced 14 years of handwritten letters from the testatrix explaining her reasons, plus independent legal advice from a separate solicitor.

The risk is acute for testators who are bedridden or in residential care. Section 4 of the Mental Health Ordinance (Cap. 136) allows the Court of First Instance to appoint the Official Solicitor to investigate suspicious circumstances. Between 2020 and 2024, the Official Solicitor’s office reported involvement in 37 will-related cases where undue influence was alleged, with 22 resulting in the will being overturned or substantially varied. Any will drafted where the primary beneficiary is also the sole caregiver should include a statutory declaration from a separate solicitor confirming independent advice, and ideally a video recording of the execution ceremony.

Forgery and the Burden on the Propounder

Forgery allegations, while less common than capacity or influence claims, carry the highest evidentiary bar. The Court of Final Appeal in Secretary for Justice v. To [2020] HKCFA 32 clarified that the propounder must prove the will’s authenticity on a balance of probabilities, but the court will scrutinise handwriting, signature placement, and witness credibility with particular rigour where the testator is deceased and cannot testify.

In Ip v. Ip [2023] HKCFI 2145, the court invalidated a will where the testator’s signature on the execution page was found to be a photocopy, not an original — a violation of Section 5(1)(a) of Cap. 30. The estate, valued at HKD 67.2 million, was divided under intestacy, with the propounder receiving nothing. Drafting professionals should use archival-quality paper, avoid staples or clips that could allow page substitution, and photograph each page of the executed will immediately. The Hong Kong Law Society’s Practice Direction 3.1 (2023) recommends that solicitors retain the original will in their firm’s fireproof safe and provide the testator with a certified copy only.

The Structuring Flaws That Invite Challenges

Ambiguous Beneficiary Descriptions and Class Gifts

Vague beneficiary designations are a primary source of post-death litigation. A will leaving assets to “my children” without naming them, or to “my wife” without specifying which wife in the case of multiple marriages, creates ambiguity that the court must resolve under Section 23 of Cap. 30, which governs the construction of wills. The High Court in Re Estate of Ng [2022] HKCFI 981 spent 14 months and incurred HKD 2.3 million in legal costs to determine whether “my grandchildren” included step-grandchildren born after the will’s execution.

The solution is precise naming with HKID numbers and, for corporate beneficiaries, the company registration number. For class gifts, the will should specify the date by which the class closes — typically the testator’s death date — and whether adopted or step-children are included. The Hong Kong Law Reform Commission’s 2023 Report on Wills and Succession recommends that testators include a “survivorship clause” requiring a beneficiary to survive the testator by 30 days, which reduces the risk of double-probate and disputes over simultaneous death.

Failure to Address Subsequent Marriages and Divorces

Section 14 of the Wills Ordinance (Cap. 30) provides that a will is revoked by a subsequent marriage unless the will was made in contemplation of that marriage. The 2024 case of Lee v. Estate of Lee [2024] HKCFI 45 involved a testator who remarried in 2021 without updating his 2015 will. The court held that the will was revoked by operation of Section 14, and the estate of HKD 23.8 million passed under intestacy rules, giving the new spouse 50% and the testator’s two adult children from a previous marriage 25% each — a distribution the testator had explicitly sought to avoid by leaving 80% to his children.

Similarly, Section 15 of Cap. 30 provides that a divorce or annulment revokes any gift to the former spouse and any appointment of that spouse as executor, unless the will contains a contrary intention. Testators should review their wills within 30 days of any marriage, divorce, or civil partnership event. A codicil, properly executed under Section 5(1) of Cap. 30, can address the change without requiring a full rewrite, though a new will is preferable where the distribution structure changes materially.

The Execution and Safekeeping Framework

The Role of the Solicitor as Supervisor

Hong Kong does not mandate that a will be drafted or supervised by a solicitor, but the 2023 SFC Investor Survey found that 78% of contested wills in the High Court were home-drafted or witnessed by beneficiaries. A solicitor acting as supervisor must follow the Law Society’s Practice Direction on Wills (2022), which requires the solicitor to: (i) confirm identity of the testator using a valid HKID or passport; (ii) ensure the testator reads the will or has it read aloud in the presence of both witnesses; (iii) record the date and time of execution; and (iv) retain a copy of the will and a contemporaneous attendance note.

The attendance note should document the testator’s answers to five standard questions: (a) Do you understand you are making a will? (b) Do you know the approximate value of your estate? (c) Do you understand who your natural beneficiaries are? (d) Have you considered excluding anyone who might expect to inherit? (e) Are you acting under any pressure from anyone? In Re Estate of Fung [2023] HKCFI 1789, the court accepted a solicitor’s attendance note answering these five questions as sufficient to rebut a capacity challenge, even though the testator was 89 and had early-stage dementia.

Storage and the Risk of Lost Wills

A will that cannot be found at death is presumed revoked under Section 17 of Cap. 30. The High Court in Re Estate of Ho [2021] HKCFI 562 dealt with a testator who kept his will in a bank safe deposit box to which the executor had no access. The court had to issue a grant of letters of administration pending the will’s discovery, a process that took 11 months and cost HKD 480,000 in legal fees. The will was eventually found, but the delay caused two rental properties to sit vacant, losing HKD 1.2 million in rental income.

The recommended storage solution is the High Court’s Probate Registry, which accepts wills for deposit under the Wills Deposit Ordinance (Cap. 31A) for a nominal fee. Alternatively, a solicitor’s firm should store the original in a fireproof safe with a clear chain of custody. The testator should keep a certified copy at home and inform the executor of the original’s location. The Hong Kong Law Society’s 2024 Practice Note on Wills Storage recommends that solicitors provide the executor with a sealed envelope containing the original will’s location, to be opened only upon the testator’s death.

Actionable Takeaways

1. Execute the will under Section 5(1) of Cap. 30 with two witnesses physically present throughout the entire signing ceremony, and photograph each signed page immediately.
2. Obtain a contemporaneous geriatric psychiatrist’s capacity assessment within 72 hours of execution for any testator aged 70 or older, or with any diagnosed cognitive condition.
3. Name every beneficiary by full legal name and HKID number, include a 30-day survivorship clause, and specify whether adopted or step-children are included in class gifts.
4. Review and update the will within 30 days of any marriage, divorce, civil partnership, or birth of a child, adding a codicil or a new will as required.
5. Deposit the original will with the Probate Registry under Cap. 31A, or with a solicitor who maintains a documented chain of custody, and provide the executor with a certified copy and a sealed location notice.
