Update: succession planning across Hong Kong Singapore

Families operating across the Hong Kong–Singapore corridor face a structural tension that does not resolve itself over time. Hong Kong holds common-law trust protections strengthened by the Trustee Ordinance reforms that took effect on 1 December 2013. Singapore runs its own trust and estate-planning regime, with a different set of default rules on accumulation periods, reserved powers and the treatment of foreign forced-heirship claims. When a family's assets, residences and professional interests span both cities, the choice of governing law for any trust or succession instrument is rarely obvious – and the consequences of the default choice can be difficult to reverse.

Succession planning across Hong Kong and Singapore requires coordinated structuring of trust siting, governing-law selection and asset-titling across two distinct common-law regimes. The Hong Kong Trustee Ordinance (Cap. 29) abolishes the rule against perpetuities for Hong Kong-law trusts and offers statutory firewall (anti-forced-heirship protection) provisions. Singapore law provides an alternative but different regime. The interaction determines whether foreign forced-heirship rules from a third country – a civil-law family jurisdiction, for instance – can reach assets held in either centre.

This briefing identifies the structural trigger, the families it currently affects, and the immediate planning step.

What the structural trigger is

The trigger is familiar on our desk: a family with principals in both Hong Kong and Singapore, real estate or operating assets in the Mainland or Southeast Asia, and a trust instrument drafted years ago under a single governing law that no longer reflects the family's actual map.

Three patterns recur. First, a Hong Kong-sited trust drafted before the 2013 reform to the Trustee Ordinance – meaning it pre-dates the statutory abolition of the rule against perpetuities and the modern reserved-powers protection. The instrument may still carry a perpetuity period or settlor-power limitations that the current law would not impose. Second, a Singapore-law trust or will that does not account for Hong Kong-situated assets and their treatment on death or distribution. Third, and most common now, a family that has added a Singapore permanent-resident principal or moved a holding entity to Singapore without reviewing whether the succession instruments address the change in residence.

What changed recently is the surrounding environment, not one statute. The sustained growth of family-office registration in Singapore has moved principals across the straits. Singapore's variable capital company structure has become a vehicle of choice for certain asset-holding arrangements. At the same time, Hong Kong has confirmed through its own Private Wealth practice environment – including the 2013 Trustee Ordinance reforms – that it remains a well-tested jurisdiction for trust structures with Mainland China or regional exposure.

When a family sits in both cities, any gap between the instruments can be exploited. A civil-law heir in a third jurisdiction can challenge the distribution on the basis of forced-heirship rules of their home country. Whether the Hong Kong firewall provisions apply depends on whether the trust is governed by Hong Kong law and whether the assets are correctly titled into that structure. A Singapore-law trust does not carry the Hong Kong statutory firewall. That distinction matters when the family's heirs include nationals of a jurisdiction with mandatory heirship rules – France, Germany, the UAE, or a number of civil-law Asian states.

For principals with Mainland China exposure specifically, the analysis becomes more layered. Our analysis of asset protection for principals with Mainland China exposure sets out the interaction between trust siting, Mainland asset titling and forced-heirship risk in detail. The cross-border enforcement question – whether a foreign judgment on inheritance can be recognised in Hong Kong or, separately, in the Mainland – adds a further layer that the succession instruments must address at drafting stage, not after the event.

Who it affects and the immediate action

The families most directly affected are those with one or more of the following: a principal who holds Hong Kong permanent residency and Singapore long-term residence simultaneously; a trust instrument more than seven years old that has not been reviewed since the 2013 Trustee Ordinance reform; assets in both Hong Kong and Singapore that are not consistently titled into the same governing structure; or heirs who are nationals of a civil-law jurisdiction with mandatory heirship rules.

The immediate action is a structured review of three documents: the governing trust deed, the will for each jurisdiction's situated assets, and the letter of wishes. The review tests four questions. Does the governing law of the trust attract the Hong Kong firewall provisions? Are Hong Kong-situated assets correctly titled into the structure, or held personally? If a principal has relocated to Singapore, does the instrument address that change of residence and its effect on the trust's connection to Hong Kong law? And do the wills for Hong Kong and Singapore assets operate consistently, or do they create a gap that could result in partial intestacy?

The sequencing matters. A trust deed amendment or re-siting exercise requires trustee consent and, in some structures, beneficiary notification. It is not a rapid process. Starting after an adverse event – a principal's incapacity, a family dispute, or a forced-heirship claim – forecloses options that are open now. For families holding assets through a trust structure that also interfaces with a UAE holding entity, the considerations we outline in our note on private trust structures for family assets in the UAE are relevant in parallel.

The sequence above describes the standard position. Your matter turns on the specific instruments, the jurisdictions actually engaged, and the current residence and asset-titling position – which is where the planning is won or lost.

Frequently asked questions

What documents are needed for succession planning across Hong Kong and Singapore?

The core documents are the governing trust deed, a will for each jurisdiction where assets are situated, and a letter of wishes addressed to the trustee. A review should also cover the asset-titling record – showing which assets are held personally and which are held through the trust structure – and any existing powers of attorney. Where a Hong Kong-law trust is in place, the trust deed should be checked against the Trustee Ordinance (Cap. 29) as amended from 1 December 2013, since earlier instruments may contain provisions that are now either unnecessary or inconsistent with the current statutory default rules.

Do I need a Hong Kong adviser for succession planning across Hong Kong and Singapore?

Yes, where Hong Kong-situated assets or a Hong Kong-law trust are involved. The Hong Kong Trustee Ordinance firewall provisions, the treatment of reserved powers and the abolition of the rule against perpetuities are Hong Kong-specific. A Singapore adviser working alone will not have the same command of the Hong Kong position, and the reverse applies equally. Effective planning across the corridor requires coordinated advice across both systems, with each adviser addressing the interface explicitly. Lockhart & Yip advises on international and foreign law in this context, working alongside locally licensed firms on Hong Kong-law matters.

How long does succession planning across Hong Kong and Singapore usually take?

A structural review of existing instruments typically takes several weeks. Implementing changes – amending a trust deed, executing new wills, or re-titling assets into the trust structure – takes longer and depends on trustee responsiveness, the number of assets involved, and whether third-party consents are required. Families with Mainland China assets or civil-law heirs should allow additional time for the cross-border analysis. Beginning the process before any adverse event is always advisable; options narrow significantly once a dispute or incapacity event occurs. Parties should verify the current position with their advisers before acting.
