Getting married in Hong Kong automatically revokes any will you made before the wedding.
This is not a commonly known rule. Most people assume a will stays valid unless they actively cancel it. But under section 14 of the Wills Ordinance (Cap. 30), marriage is one of the few events that voids a will automatically, without any action from you.
The moment you sign your marriage certificate, your previous will becomes legally ineffective. Your estate would then be distributed according to Hong Kong intestacy law (Cap. 73), as if you had never made a will at all.
Why the law works this way
The rule exists because marriage represents a fundamental change in your personal and legal circumstances. The law assumes that a will made before your marriage may not reflect your intentions now that you have a spouse. Rather than leaving that uncertainty unresolved, it wipes the slate clean.
The practical consequence is significant. If you made a will leaving everything to your parents, your siblings, or a previous partner, and you then marry without updating your will, none of those wishes have any legal force. Your new spouse may receive far less than you intended, or your estate may be distributed in a way that neither of you would have chosen.
What happens to your estate after marriage with no new will
Without a valid will, your estate is distributed under Cap. 73 intestacy rules. The outcome depends on your family situation at the time of death.
Your spouse receives all personal belongings plus HKD 500,000, plus half of the remaining estate. Your children split the other half.
Your spouse receives all personal belongings plus HKD 1,000,000, plus half of the remaining estate. If your parents are alive, they share the other half equally.
Your children split the entire estate equally.
