Making a Valid Will in Hong Kong: Requirements, Capacity, and Common Pitfalls

Introduction

A will is one of the most important legal documents a person can prepare. It determines how your estate will be distributed after your death, appoints the people you trust to administer your affairs, and can include crucial provisions for the care of minor children or dependants. Yet many Hong Kong residents either have no will or hold wills that are poorly drafted and potentially invalid.

This guide explains the legal requirements for a valid will under Hong Kong law, what constitutes testamentary capacity, common errors that can invalidate a will, and how disputes over wills are resolved.

Legal Framework: The Wills Ordinance

Wills in Hong Kong are governed primarily by the Wills Ordinance (Cap. 30), which sets out the formal requirements for a valid will, the rules on revocation and revival, and the treatment of gifts to witnesses and their spouses. The Intestates’ Estates Ordinance (Cap. 73) governs the distribution of estates where a person dies without a valid will (intestate).

Who Can Make a Will?

Age

A testator must be at least 18 years old to make a valid will, unless they are a mariner at sea or a member of the armed forces on active service, in which case a privileged will may be made without the usual formalities.

Testamentary Capacity

The testator must have testamentary capacity – the mental ability to make a valid will. The classic legal test for testamentary capacity was established in Banks v Goodfellow (1870), which remains the leading authority in Hong Kong. To have testamentary capacity, the testator must:

• Understand the nature of making a will and its effects;
• Understand the extent of the property they are disposing of (though not necessarily in precise detail);
• Comprehend the claims of those who might expect to benefit (typically family members), even if they choose not to benefit them;
• Not be suffering from any disorder of the mind that poisons their affections, perverts their sense of right, or prevents the exercise of their natural faculties in disposing of their property.

A person may have testamentary capacity even if they have been diagnosed with dementia, provided that at the time of executing the will they had a “lucid interval” meeting the above requirements. Where testamentary capacity is in doubt, a medical assessment and contemporaneous file notes from the will-drafting solicitor are critically important.

Formal Requirements for a Valid Will

Under section 5 of the Wills Ordinance, a will must:

• Be in writing (including typewritten or printed; electronic wills are not recognised in Hong Kong as of 2025);
• Be signed by the testator, or by another person in the testator’s presence and at their direction, at the foot or end of the will;
• Be witnessed by two witnesses who are both present at the time the testator signs (or acknowledges their signature), and who each sign in the testator’s presence.

Witnesses

Witnesses must be present simultaneously when the testator signs or acknowledges their signature. A witness cannot be:

• A beneficiary under the will;
• The spouse or civil partner of a beneficiary.

If a beneficiary or their spouse witnesses the will, the will is not invalid, but the gift to that beneficiary is void – a common and avoidable mistake. Witnesses should be adults who are competent to give evidence in court.

Position of Signature

The testator’s signature must appear “at or after, or following, or under, or beside, or opposite the end of the will,” in a position that makes clear the intention to give effect to the whole will. Signatures in the middle of the will or above the body of text create validity risks.

Common Mistakes That Invalidate Wills

• Witnessing by a beneficiary or their spouse – voids the gift to that beneficiary;
• Incomplete execution – only one witness present, or witnesses signing at different times;
• Unattested alterations – handwritten changes made after execution are invalid unless separately initialled and witnessed;
• Lack of testamentary capacity – will executed during a period of mental incapacity;
• Undue influence – the testator was pressured into making the will in a particular way;
• Fraud – the testator was deceived about the nature of the document they were signing;
• Revocation by marriage – under Hong Kong law, a will is automatically revoked upon the testator’s marriage, unless the will was made “in contemplation of” that specific marriage.

Revocation of a Will

A will may be revoked by:

• Marriage – automatically (unless the will was made in contemplation of the marriage);
• A later valid will – the later will expressly or impliedly revokes the earlier one;
• A written declaration of revocation – signed and witnessed with the same formalities as a will;
• Physical destruction – burning, tearing, or otherwise destroying the will with the intention to revoke it (destruction without the intention to revoke is not effective revocation).

Divorce does not revoke a will in Hong Kong. However, under the Wills Ordinance, upon divorce any gift to a former spouse and any appointment of the former spouse as executor takes effect as if the former spouse had died on the date of the divorce.

Intestacy: What Happens Without a Valid Will

If a person dies without a valid will (intestate), their estate is distributed according to the Intestates’ Estates Ordinance (Cap. 73). The distribution rules prioritise the spouse and children. Under the current rules for a person leaving a spouse and children:

• The spouse receives the personal chattels absolutely, plus the first HKD 500,000 of the residuary estate, plus one-half of the remainder;
• The children share equally the other half of the remainder.

Notably, unmarried partners receive nothing under intestacy rules – a significant risk for cohabiting couples who have not made wills.

Challenging a Will

A will may be challenged in the Hong Kong courts on several grounds:

• Lack of testamentary capacity at the time of execution;
• Undue influence – the testator was coerced, manipulated, or subjected to pressure that overwhelmed their free will;
• Fraud or forgery – the will is a forgery or the testator was deceived;
• Failure to comply with formalities (e.g., improper witnessing);
• Suspicious circumstances – where the will was prepared by or for the benefit of a person who was involved in the drafting, placing the burden of proof on the propounder of the will.

A successful challenge results in the will (or a specific provision) being declared invalid. The estate then either falls into a prior valid will or is distributed on intestacy.

Inheritance (Provision for Family and Dependants)

Under the Inheritance (Provision for Family and Dependants) Ordinance (Cap. 481), certain classes of persons – including spouses, former spouses not remarried, children, and dependants – may apply to the court for reasonable financial provision from the estate, even if the deceased’s will makes no or inadequate provision for them. Applications must generally be made within six months of the grant of probate.

Practical Guidance for Will-Making

• Use a solicitor – professionally drafted wills reduce the risk of invalidity and ambiguity. DIY will kits carry significant risks.
• Review your will after major life events – marriage, divorce, birth of children, significant asset acquisitions, or death of a named executor or beneficiary;
• Appoint backup executors – always name an alternate executor in case your primary executor predeceases you or is unable to act;
• Address your Hong Kong and overseas assets separately – consider whether a separate will is needed for properties in other jurisdictions;
• Consider capacity issues proactively – if there is any risk of future mental incapacity, execute a will (and a Lasting Power of Attorney) while capacity is unquestionable, with contemporaneous medical evidence.
