Without a valid will in Hong Kong, your estate passes under the Intestates' Estates Ordinance (Cap. 73), a statutory formula that ignores your actual wishes. Common-law partners receive nothing. Mainland China assets are governed by PRC succession law regardless of what any Hong Kong will says. For most adults with property, savings, or dependants in Hong Kong, the answer to the title question is yes — a will is not optional.
What intestacy actually means under Cap. 73
The Intestates' Estates Ordinance (Cap. 73) sets out a fixed distribution hierarchy. The order of priority is: surviving spouse, children, parents, siblings, half-siblings, grandparents, uncles and aunts, and half-uncles and half-aunts. If none of those relatives survive, the estate escheats to the Government of Hong Kong under the Government Rights (Re-entry and Vesting Remedies) Ordinance (Cap. 126).
The spousal share is more complicated than it looks. Where a spouse survives together with issue (children or their descendants), the spouse receives all personal chattels, a fixed net sum of HK$500,000, and one half of the residuary estate. The other half goes to the issue in equal shares per stirpes. Where no issue survive, the spouse takes the whole estate only if no parent, sibling, or sibling's issue also survives — otherwise the spouse shares the residue with those relatives. The formula has not been comprehensively revised for many years, and the HK$500,000 statutory legacy is a modest figure relative to Hong Kong property values.
Common-law partners: entirely excluded
Hong Kong does not recognise common-law marriage. A partner who has lived with the deceased for ten, twenty, or thirty years acquires no automatic entitlement under Cap. 73. The Inheritance (Provision for Family and Dependants) Ordinance (Cap. 481) allows certain dependants — including a person maintained by the deceased immediately before death — to apply to court for reasonable financial provision. But that is litigation, not certainty. The court has discretion, the process takes time and money, and the outcome is unpredictable. A will eliminates the need for that application entirely. Same-sex partners face the same exclusion; Hong Kong does not recognise same-sex marriage or civil unions for succession purposes.
The mainland China complication
Many Hong Kong residents own property in Guangdong or elsewhere in mainland China — a flat bought before the handover, a family home inherited from parents, or an investment purchased through the Qualified Domestic Institutional Investor channel. A Hong Kong will has no legal effect over real property situated in mainland China.
PRC succession law (the Civil Code of the People's Republic of China, Book VI on Inheritance, effective 1 January 2021) applies to immovable property located in the mainland. The distribution hierarchy under PRC law differs from Cap. 73 in several respects. First-order heirs are spouses, children, and parents; grandparents are second-order heirs who inherit only when no first-order heirs survive. Non-marital children have equal rights to marital children. A PRC notarial succession certificate or a court judgment is required before a mainland registry will transfer title.
Practically, this means a deceased Hong Kong resident may leave behind two separate succession processes running in parallel — a Hong Kong probate application and a mainland notarial or judicial process — governed by different laws, requiring different documents, in different languages. A Hong Kong will that recites mainland property may also create confusion about testamentary intent and jurisdiction. The cleaner approach is a separate mainland testament executed before a PRC notary, dealing specifically with mainland assets, alongside the Hong Kong will for Hong Kong assets.
What a Hong Kong will must do to be valid
The Wills Ordinance (Cap. 30) sets the requirements. The testator must be at least eighteen years old and of sound mind. The will must be in writing and signed by the testator (or by another person in the testator's presence and by the testator's direction). The signature must be made or acknowledged in the presence of two witnesses present at the same time, and both witnesses must sign in the testator's presence. A beneficiary who witnesses the will forfeits the gift to them — so beneficiaries should never act as witnesses.
The will should appoint an executor, state who receives specific assets and the residue, and ideally address guardianship of minor children. A well-drafted will can also include a survivorship clause (requiring a beneficiary to survive by a set period, such as thirty days, before inheriting) and a substitution clause in case a primary beneficiary predeceases the testator.
Grants of probate and letters of administration
When a person dies with a valid will, the executor applies to the High Court of Hong Kong for a grant of probate. When a person dies intestate, the next of kin applies for letters of administration. Both processes go through the Probate Registry. Letters of administration require an administration bond in most cases, adding procedural complexity and cost compared with a standard probate application.
The Probate and Administration Ordinance (Cap. 10) governs both processes. Estate duty was abolished in Hong Kong in 2006, so there is no inheritance tax in the general sense — but professional fees for administering an intestate estate, particularly one that requires litigation over entitlement, can be substantial.
Specific assets that fall outside a will
Some assets pass by operation of law regardless of what any will says. Joint tenancy property — where two or more people hold legal title as joint tenants — passes to the surviving joint tenant(s) automatically on death by right of survivorship. Many Hong Kong couples hold residential property this way. An asset held in a trust vests according to the trust deed, not the will. Pension scheme benefits and Mandatory Provident Fund (MPF) accrued benefits pass to nominated beneficiaries under the Mandatory Provident Fund Schemes Ordinance (Cap. 485) and the Occupational Retirement Schemes Ordinance (Cap. 426) respectively. Life insurance proceeds go to the policy's named beneficiary.
Understanding which assets fall inside and outside the estate is essential before drafting a will. A will that attempts to dispose of an asset held on joint tenancy, for instance, has no effect on that asset.
Why intestacy is riskier than it looks
The Cap. 73 formula was designed to approximate what a typical person might want. For many families it produces a reasonable outcome. But typical families in Hong Kong are often not straightforward: blended families with children from prior relationships, elderly parents who depend financially on the deceased, partners who are not legally married, non-resident relatives with competing claims, and assets split across two legal systems.
Consider a scenario: a Hong Kong resident dies intestate leaving a spouse, two children from a previous marriage, and a Shenzhen apartment. Under Cap. 73, the spouse receives HK$500,000 and half the Hong Kong residue; the children split the other half. The Shenzhen apartment goes into a separate mainland succession process, potentially drawing in PRC relatives who would not inherit under a deliberately drafted will. The spouse may end up with far less than the deceased intended, and the resolution may take years.
A simple will for Hong Kong addresses each of these points directly: who gets what, who administers the estate, and — if children are minors — who cares for them. The document does not require a solicitor to be valid, though professional advice is worth considering for anything involving mainland assets, trusts, or complex family arrangements.
What to do if you have mainland assets
Get separate legal advice from a PRC-qualified lawyer or a notary public in mainland China. Execute a mainland testament in Chinese before a mainland notary office, dealing specifically with your immovable PRC property. Keep the two wills consistent — do not inadvertently revoke or contradict one with the other. Both documents should contain revocation clauses that expressly carve out assets governed by the other jurisdiction.
Some law firms in Hong Kong specialise in cross-border succession and can coordinate both documents. The cost is modest relative to the complexity that intestacy creates across two legal systems.
The practical bottom line
Any Hong Kong adult who owns property, has savings over a trivial amount, supports dependants, or is in a relationship that is not a recognised legal marriage should have a valid will. The Cap. 73 intestacy rules are not a neutral default — they are a fixed formula that can produce outcomes quite different from what most people would choose. Common-law partners are left with nothing except expensive litigation. Mainland assets are outside the will's reach regardless. The two-witness rule and the writing requirement under the Wills Ordinance (Cap. 30) are not onerous. Putting a will in place is one of the more straightforward steps in managing a Hong Kong estate — leaving it undone is the complicated choice.
