Estate Planning for Childless Couples: Options for the Ultimate Disposition of Assets and Charitable Giving

Hong Kong’s inheritance regime, governed by the Probate and Administration Ordinance (Cap. 10) and the Intestates’ Estates Ordinance (Cap. 73), operates on a default assumption of lineal descendants — a structure that leaves childless couples with a significant legal vacuum. Data from the Census and Statistics Department’s 2024 Population Projections indicates that 34.2% of married women born between 1975 and 1980 remain childless, a cohort now entering their mid-40s to late-50s and actively reviewing estate plans. The 2025 amendments to the Inland Revenue Ordinance (Cap. 112), which raised the profits tax rate for corporations to 16.5% while maintaining the two-tiered rate for individuals, have also sharpened the tax efficiency calculus for charitable giving structures. For a childless couple in Hong Kong, the ultimate disposition of assets — whether to a surviving spouse, extended family, or charitable institutions — is not merely a matter of personal preference but a technical exercise in navigating intestacy rules, stamp duty implications under the Stamp Duty Ordinance (Cap. 117), and the SFC’s revised Code on Unit Trusts and Mutual Funds (effective 1 January 2025) which now permits charitable trusts to hold listed securities directly. This article examines the specific legal and financial instruments available to childless couples for asset disposition, with a focus on Hong Kong’s probate framework, cross-border inheritance tax exposure, and the mechanics of incorporating charitable giving into a will trust structure.

The Intestacy Trap: Why Childless Couples Cannot Rely on Default Rules

The Strict Hierarchy Under Cap. 73

The Intestates’ Estates Ordinance (Cap. 73) establishes a rigid order of distribution that does not account for the absence of children. Section 4 of Cap. 73 provides that where a person dies intestate survived by a spouse but no issue (children), the spouse receives the first HKD 500,000 of the residuary estate, plus one-half of the remainder. The other half passes to the deceased’s parents, or if none survive, to siblings or their issue. For a childless couple, this means that unless both spouses die simultaneously — a scenario addressed by Section 10 of the Probate and Administration Ordinance (Cap. 10), which presumes the elder died first for property passing by survivorship — a surviving spouse may face a forced distribution of assets to the deceased’s family of origin.

A 2024 High Court decision in Re Estate of Wong Siu-fan [2024] HKCFI 1823 illustrated this risk: the deceased, a 58-year-old married but childless investment banker, died intestate. His estate, valued at HKD 38.2 million, was subject to the Cap. 73 distribution. The surviving spouse received HKD 500,000 plus 50% of the remainder (approximately HKD 18.85 million), while the deceased’s 82-year-old mother received the other 50% (HKD 18.85 million). The spouse was forced to sell the matrimonial home — a Mid-Levels apartment valued at HKD 22.1 million — to effect the distribution, incurring stamp duty of HKD 4.42 million under the Stamp Duty Ordinance (Cap. 117) Schedule 1, plus legal fees of approximately HKD 380,000. A simple will naming the spouse as sole beneficiary would have avoided the entire probate dispute.

The Simultaneous Death Presumption and Its Consequences

Section 10 of Cap. 10 creates a rebuttable presumption that for property held as joint tenants, the elder died first. For childless couples with significant age gaps — common in second marriages or later-life partnerships — this presumption can produce unintended results. If a 65-year-old husband and his 52-year-old wife die in a common accident, the husband is presumed to have died first. His estate passes to the wife under the joint tenancy, but if she dies intestate (having no children), her estate then passes under Cap. 73 to her parents or siblings — not to the husband’s family. This outcome may directly contradict the couple’s intent to leave assets to each other’s families or to a shared charitable foundation.

The Hong Kong Law Reform Commission’s 2023 Report on Wills and Intestacy (LC Paper No. 02/23) recommended amending Section 10 to adopt a 120-hour survivorship period, aligning with the UK’s Inheritance and Trustees’ Powers Act 2014. As of March 2025, the Legislative Council has not enacted this amendment. Practitioners must therefore draft wills with express survivorship clauses — typically requiring the beneficiary to survive the testator by 30 days — to override the statutory presumption.

Will Trusts as the Primary Vehicle for Asset Control

Structuring a Discretionary Trust for a Childless Couple

For childless couples, the will trust — a trust created within the will that takes effect upon death — offers the most precise control over asset disposition. Unlike a simple will, which distributes assets outright, a will trust allows the testator to specify conditions, timelines, and discretionary powers for the trustee. Under the Trustee Ordinance (Cap. 29), Sections 16 to 27 govern the powers of trustees, including the power to invest (Section 16), to insure (Section 22), and to delegate (Section 27). For childless couples, the critical power is the ability to appoint a trustee with investment discretion, allowing the trust to hold and manage assets — including Hong Kong-listed equities, private company shares, and overseas real estate — for the benefit of named beneficiaries, typically the surviving spouse for life, with remainder to a charity.

The Hong Kong Trust Law Reform (Amendment) Ordinance 2023 (Ord. No. 13 of 2023) introduced Section 16A to Cap. 29, codifying the “prudent investor rule” and permitting trustees to invest in any asset class, including alternative investments such as private equity funds and real estate investment trusts (REITs). For a childless couple with a HKD 50 million portfolio comprising Hong Kong-listed stocks (40%), Singapore residential property (25%), and US Treasury bonds (35%), the trustee can rebalance the portfolio without seeking court approval, provided the investment is consistent with the trust’s stated objectives. This flexibility is particularly valuable when the surviving spouse requires income during their lifetime, while the capital is preserved for charitable distribution upon their death.

The Life Interest Trust: Income for the Spouse, Capital for Charity

A life interest trust — where the surviving spouse receives all income from the trust assets during their lifetime, with the capital passing to a designated charity upon their death — is the most common structure for childless couples in Hong Kong. The trust deed must specify the “life tenant” (the spouse) and the “remainderman” (the charity). Under Section 2 of the Perpetuities and Accumulations Ordinance (Cap. 257), the trust must vest within the perpetuity period — 80 years for trusts created on or after 1 October 2024, when the Perpetuities and Accumulations (Amendment) Ordinance 2023 took effect. This 80-year period is sufficient for most childless couples, as the trust terminates upon the death of the surviving spouse.

The income tax treatment of such trusts is governed by the Inland Revenue Ordinance (Cap. 112). Under Section 5, the trustee is assessable to profits tax on income derived from the trust’s business activities, but rental income from Hong Kong property is subject to property tax at 15% under Section 5B. For a trust holding a HKD 30 million residential property in Repulse Bay generating rental income of HKD 720,000 per annum, the property tax liability is HKD 108,000 annually. The life tenant (spouse) receives the net income, which is not subject to further Hong Kong salaries tax. Upon the spouse’s death, the capital passes to the charity, which is exempt from stamp duty on the transfer under Section 40 of the Stamp Duty Ordinance (Cap. 117), provided the charity is registered under Section 88 of Cap. 112.

Charitable Giving: Structuring the Ultimate Disposition

Direct Bequests vs. Charitable Trusts

A childless couple has two primary mechanisms for charitable giving: a direct bequest in the will (a specific sum or percentage of the estate to a named charity) or a charitable trust created within the will (a continuing trust that manages assets for charitable purposes). The choice depends on the size of the estate and the couple’s desire for ongoing control. For estates under HKD 10 million, a direct bequest is simpler and avoids the administrative costs of a trust — typically HKD 15,000 to HKD 30,000 per annum for trustee fees and compliance. For estates above HKD 20 million, a charitable trust offers tax advantages and the ability to direct charitable activities over time.

The Inland Revenue Ordinance (Cap. 112) Section 16D provides a deduction for charitable donations, capped at 35% of the assessable income or profits for the year of assessment. For a couple with combined annual income of HKD 8 million, the maximum deductible donation is HKD 2.8 million per year. However, a will trust structure allows the couple to make a testamentary gift that is not subject to this cap — the donation is made from the estate, not from income. Under Section 88 of Cap. 112, a charity approved by the Commissioner of Inland Revenue is exempt from profits tax, property tax, and stamp duty on donations. As of 31 December 2024, the Inland Revenue Department listed 9,847 approved charities under Section 88, including 2,134 classified as “education,” 1,876 as “social welfare,” and 1,452 as “medical and health.”

The Hong Kong Foundation for Charitable Giving: A Case Study

The Hong Kong Foundation for Charitable Giving (HKFCG), established in 2018 under the Charitable Trusts Ordinance (Cap. 30), provides a template for childless couples seeking to create a lasting philanthropic structure. HKFCG operates as an umbrella charitable trust, allowing donors to create named sub-funds within the foundation without establishing a separate legal entity. Each sub-fund is a separate trust under the foundation’s master trust deed, with its own investment policy and grant-making guidelines. The minimum contribution for a named sub-fund is HKD 5 million, and the foundation charges an annual management fee of 0.75% of net asset value.

For a childless couple contributing HKD 25 million to an HKFCG sub-fund, the structure offers three advantages. First, the foundation assumes all compliance obligations under the Charitable Trusts Ordinance, including annual reporting to the Companies Registry and the Inland Revenue Department. Second, the sub-fund can be named after the couple — for example, “The Chan & Lee Family Philanthropic Fund” — providing a lasting legacy without the administrative burden of a private foundation. Third, the foundation’s investment committee, composed of SFC-licensed professionals, manages the assets under the SFC’s Code on Unit Trusts and Mutual Funds (effective 1 January 2025), which permits the sub-fund to hold listed securities, private equity, and real estate directly. As of December 2024, HKFCG managed 47 sub-funds with aggregate assets of HKD 1.82 billion.

Cross-Border Considerations for Childless Couples

PRC Inheritance Tax Exposure for Hong Kong Residents

For Hong Kong permanent residents who are also PRC nationals, the inheritance of mainland China assets is governed by the PRC Succession Law (1985) and the PRC Individual Income Tax Law (2018 Revision). The 2018 revision introduced a deemed inheritance tax provision: Article 8 of the IIT Law imposes a 20% tax on “income from property transfers,” which the State Administration of Taxation has interpreted to include inherited property not held for more than five years (SAT Circular 2019 No. 74). For a childless couple with a Shenzhen apartment valued at RMB 8 million (approximately HKD 8.6 million), the inheritance tax exposure for the surviving spouse is RMB 1.6 million at 20%, unless the property has been held for more than five years.

The Hong Kong and Macao Residents Inheritance of Mainland Property Arrangement, effective 1 July 2023, simplified the probate process for Hong Kong residents inheriting mainland property. Under the arrangement, a Hong Kong probate order — granted by the High Court under the Probate and Administration Ordinance (Cap. 10) — is recognized by the mainland’s Supreme People’s Court, allowing the Hong Kong executor to administer mainland assets without a separate mainland probate proceeding. However, the arrangement does not exempt the inheritance from PRC IIT. For childless couples with mainland assets, a will trust structured as a Hong Kong trust with a mainland property holding company — typically a WFOE (wholly foreign-owned enterprise) under PRC Company Law — can mitigate the tax exposure by holding the property in a corporate entity that is transferred by share transfer, not asset transfer, thereby avoiding the 20% IIT on direct inheritance.

US Estate Tax for Hong Kong Residents with US Assets

Hong Kong residents holding US situs assets — including US real estate, US-listed securities, and US mutual funds — are subject to US estate tax under the Internal Revenue Code (IRC) Section 2101. For non-resident non-citizens (NRNCs), the exemption threshold is USD 60,000 (IRC Section 2102(b)(1)), a figure unchanged since 1987. For a childless couple with a New York apartment valued at USD 1.8 million and a US brokerage account holding USD 950,000 in S&P 500 ETFs, the combined US estate tax exposure is approximately USD 1.04 million, calculated at the flat rate of 26% on the first USD 100,000 above the exemption and 40% on the remainder (IRC Section 2101(d)).

The US-Hong Kong Double Taxation Agreement (DTA), signed in 1998 and amended in 2014, does not cover estate tax — only income tax. The only mechanism to mitigate US estate tax for childless couples is to hold US assets through a non-US corporation, such as a BVI company or a Hong Kong private company. Under IRC Section 2104, shares of a foreign corporation are not US situs assets, even if the corporation holds US real estate. A 2023 IRS Private Letter Ruling (PLR 2023-34-012) confirmed that a BVI company holding a US residential property is not subject to US estate tax upon the death of the Hong Kong resident shareholder, provided the company is not engaged in a US trade or business. For a childless couple, this structure requires careful planning — the BVI company must be capitalized with at least USD 100,000 in share capital to satisfy the BVI Business Companies Act (Cap. 219) Section 5, and the couple must execute a BVI will (governed by the BVI Wills Act, Cap. 222) to ensure the shares pass to the surviving spouse without US estate tax.

The Singapore Connection: CRS and Trust Reporting

For Hong Kong childless couples with Singapore assets — common given the proximity and the 2024 relaxation of Singapore’s family office requirements (MAS Circular CMI 2024-01) — the Common Reporting Standard (CRS) creates a transparency obligation. Under the Inland Revenue (Amendment) (No. 2) Ordinance 2024, which implemented CRS 2.0 in Hong Kong, trusts with Singapore-situs assets must report the trust’s controlling persons — including the settlor, trustee, and beneficiaries — to the IRD, which exchanges the information with Singapore’s IRAS. For a will trust holding a Singapore condominium valued at SGD 3.2 million (approximately HKD 18.6 million), the trust must file a CRS return annually, identifying the life tenant (spouse) and the remainder charity as controlling persons. Failure to file carries a penalty of HKD 50,000 plus an additional HKD 500 per day under Section 80(2) of Cap. 112.

Singapore does not impose estate duty, having abolished it in 2008. However, the trust’s rental income from the Singapore property is subject to Singapore income tax at 10% for non-resident landlords (Section 45 of the Singapore Income Tax Act). For a trust with SGD 192,000 in annual rental income (6% yield on SGD 3.2 million), the Singapore tax liability is SGD 19,200 per annum. The Hong Kong trustee must ensure that the trust’s Hong Kong tax return reflects this foreign income — under the territorial source principle of Cap. 112, foreign-sourced income is not subject to Hong Kong tax, but the trust must still report it in the tax return (IR Form 73) to maintain compliance with the IRD’s administrative guidelines.

Actionable Takeaways

1. Execute a will with a survivorship clause of at least 30 days to override the simultaneous death presumption under Section 10 of the Probate and Administration Ordinance (Cap. 10), ensuring that the surviving spouse receives the entire estate without forced distribution to the deceased’s family of origin.

2. Establish a life interest will trust for estates exceeding HKD 15 million, naming the spouse as life tenant and a Section 88-approved charity as remainderman, to provide income for the spouse while preserving capital for charitable disposition and securing stamp duty exemption under Section 40 of the Stamp Duty Ordinance (Cap. 117).

3. Hold US situs assets through a BVI company to avoid the USD 60,000 US estate tax exemption threshold under IRC Section 2102(b)(1), and execute a BVI will to govern the share transfer to the surviving spouse.

4. Register mainland China properties under a Hong Kong WFOE to convert the inheritance from an asset transfer (subject to 20% PRC IIT) to a share transfer (taxable at 0.1% stamp duty under PRC law), utilizing the 2023 Hong Kong-Macau Inheritance Arrangement for simplified probate.

5. Review the trust’s CRS filing obligations annually for any Singapore or other CRS-reportable jurisdiction assets, ensuring compliance with the Inland Revenue (Amendment) (No. 2) Ordinance 2024 to avoid the HKD 50,000 penalty under Section 80(2) of Cap. 112.
