Update: a will and estate plan covering assets in Singapore

For principals whose estates span Hong Kong and Singapore, the interaction between two common-law systems looks straightforward on paper. In practice, it is not. Succession law, domicile rules, and the treatment of foreign-law trusts diverge at precisely the points that matter most when an estate is administered.

A will and estate plan covering assets in Singapore must address at least two legal systems simultaneously: Singapore succession law governs immovable property situated there, while the law of the deceased's last domicile governs movable property in most cases. Where a principal is also tax-resident in Hong Kong, or holds assets through an offshore structure, a third and fourth layer applies. No single instrument covers the field.

This briefing sets out what the corridor currently requires, who is most directly affected, and the immediate planning step.

What the Hong Kong–Singapore corridor now requires

The corridor between Hong Kong and Singapore carries a structural tension that estate planners often underestimate. Singapore's Intestate Succession Act governs assets situated in Singapore where no valid will is in place, applying a fixed statutory distribution that does not adapt to family arrangements structured elsewhere. A principal who has relied on a Hong Kong will, a BVI or Cayman holding entity, or a discretionary trust settled under the laws of another jurisdiction may find that Singapore-situated assets – real property, bank deposits, brokerage accounts – fall outside the estate plan as written.

Singapore does not impose forced heirship in the civil-law sense. However, the Muslim Inheritance Law (faraid – the Quranic inheritance regime applied to Muslims domiciled in Singapore) operates separately and overrides a conventional will for affected assets. Principals of Muslim faith who hold assets in Singapore must take specific advice on this point. The interaction with a Hong Kong or offshore trust structure is non-trivial.

Hong Kong, for its part, has no forced-heirship regime. The Trustee Ordinance – substantially reformed with effect from 1 December 2013 – strengthened protection of Hong Kong-law trusts against foreign forced-heirship claims and abolished the rule against perpetuities for Hong Kong trusts. That reform does not extend automatically to Singapore-situated assets, which remain subject to Singapore law regardless of how the trust is drafted.

The trigger for review is not always a change in the law. It arises when a principal acquires a significant Singapore asset – property, a family-office account, a private-market holding – without updating the estate plan to reflect the new jurisdictional exposure. In our cross-border practice, we regularly see plans drafted five or more years ago that were sound at the time but have since been outpaced by the family's asset map.

Who is affected across the corridor

The principals most directly affected are those who hold, or are acquiring, Singapore-situated assets while their centre of life, family-office infrastructure, or holding structure sits in Hong Kong or an offshore centre. The categories include:

• Hong Kong residents with Singapore real property, managed accounts, or private-banking positions;
• Singapore-resident principals whose trusts or holding vehicles are governed by Hong Kong or offshore law;
• Families with members resident in both cities, where the question of domicile at death is genuinely uncertain;
• Principals migrating capital between the two cities as part of a broader relocation or family-office establishment.

The domicile question is the fault line. Singapore courts apply the law of the last domicile to movable property. If a principal with a long-established Hong Kong domicile of choice has spent recent years between both cities, the position at death may be contested. A contested domicile means contested law. That contest is expensive, slow, and corrosive to family cohesion.

The immediate action

The planning step is a cross-border will and structure audit. It should address three questions in sequence.

First: does the existing will or trust instrument cover Singapore-situated assets expressly, or does it rely on a catch-all that may not hold under Singapore law? A will drafted under Hong Kong law with a residuary clause does not automatically extend to Singapore immovable property without additional steps.

Second: what is the current domicile position, and is it documented? Domicile is a question of fact and intention. Where a principal has strong connections to both cities, contemporaneous documentation of intention is the most reliable defence against a dispute.

Third: does the offshore holding structure – BVI, Cayman, or similar – sit over any Singapore-situated assets, and if so, are the economic-substance and beneficial-ownership records current? Singapore's own anti-avoidance and disclosure regimes affect how offshore-held assets are treated in an estate context. Parties should verify the current position before acting.

This is not a matter to defer. An incomplete estate plan is not a neutral position. It is an open question decided by statute and by whichever court is asked to answer it first.

The sequence above describes the standard position. Your matter turns on the documents, the jurisdictions actually engaged, and the order of steps – which is where the route is won or lost.
