🇸🇬Family Office: SFO/MFO Structure, Jurisdictions, Governance and Succession

Concept

A family office is the structure that manages the capital and affairs of one family (single family office, SFO) or several (multi family office, MFO): investment, legal and tax support, succession, the education of heirs and sometimes everyday life. It is the headquarters of Flag 4, tying holdings, foundations and trusts into a single system.

The idea grew out of the practice of industrial dynasties: the Rockefeller office, traditionally regarded as the first modern family office (1882), ran the family's affairs as a single whole. Today the format is booming — according to Deloitte, there are around 8,030 single family offices worldwide against roughly 6,130 in 2019, and their number may rise to about 10,720 by 2030; assets under management from $3.1 to $5.4 trillion. Families increasingly want to manage capital systematically and gather scattered advisers under one roof.

What a family office does

The set of functions varies, but the core is stable: consolidated accounting and reporting across all assets, an investment strategy and allocation across asset classes, tax and legal support, succession and the preparation of heirs, and philanthropy. Larger offices add real estate management, art collections and sometimes concierge-level service. The broader the mandate, the more expensive the infrastructure — and the more important it is to set out in advance what the office handles itself and what it delegates to outside contractors.

SFO or MFO

An SFO serves one family and is usually justified from roughly $100–250 million in capital: it is expensive to run, but it gives full control and confidentiality. The line is set not by the headline sum but by the asset mix and the cost ratio: a minimally viable team costs much the same whatever the size of the portfolio, so on $100 million a $1 million budget already means about 100 bps a year. An MFO works for several families and spreads the cost of the team and infrastructure — a sensible entry point while a dedicated office is not yet economically justified. The choice between them comes down to a balance of cost, control and privacy; many families start with an MFO and move to an SFO as their capital grows.

An SFO's budget usually starts at $1–2 million a year: team salaries, audit, legal, IT and data storage. Even a small office's team means a CIO or investment director, a financial controller and a lawyer; the rest is outsourced to banks, asset managers and auditors. That is exactly why an MFO is attractive at the outset: the same expertise without the full fixed overhead. As assets grow and the structure becomes more complex, the family moves to its own office, where control and confidentiality outweigh the saving.

Jurisdictions

The jurisdiction is chosen for its combination of tax regime, infrastructure — banks, asset managers, lawyers — and reputation. For Russian and international families the tone is set by a trio: Singapore, the UAE and Switzerland. The first two have built regimes squarely for the family office; the third wins on the maturity of its market. The choice of hub is usually tied to the principals' citizenship and residence, banking access and where the family actually lives — which affects both tax residency and the structure's resilience to sanctions.

Singapore

Singapore offers incentives under sections 13O and 13U of the Income Tax Act: a fund's income from designated investments is exempt from tax. Under the MAS framework of 5 July 2023 the minimum assets are S$20 million for 13O and S$50 million for 13U at the point of application; at least two (13O) or three (13U) investment professionals are required, and in both regimes at least one from outside the family; no less than 10% of assets or S$10 million (whichever is lower) must be deployed into local investments. The schemes have been extended to 31 December 2029. Capital is pooled through a VCC structure; for more, see the overview of wealth planning in Singapore. The primary source on the incentives is the MAS website.

UAE

In Dubai there is the DIFC: the Family Wealth Centre has operated since 2023, and the Family Arrangements Regulations 2023 (enacted 31 January 2023) replaced the former single family office regime. The entry threshold is around $50 million in total net assets (including real estate and operating businesses), and the office manages without a separate DFSA licence. ADGM has no special family office regime — there structures use an SPV (restricted scope company) and a foundation. A family foundation in the UAE, where the conditions are met, is treated as tax-transparent and pays no corporate tax (Ministerial Decision No. 261 of 2024).

Switzerland

Switzerland's strength is its mature private banking infrastructure, political stability and reputation; there is no special family office regime here. Wealthy families combine the office with lump-sum taxation (forfait) for the principals themselves and a residence permit. Competition to these hubs comes from Hong Kong, which since 2023 has introduced its own tax incentive for single family offices and is fighting for the same capital.

Hong Kong

Hong Kong's answer is the FIHV (family-owned investment holding vehicle): a family investment vehicle's income from qualifying transactions in Schedule 16C assets is charged profits tax at 0%. The threshold is HK$240 million of assets under the management of an ESF Office (eligible single family office), which is expected to show real substance: at least two full-time employees and HK$2 million of operating expenditure in Hong Kong a year. There is no application to a regulator: the concession works by self-assessment in the profits tax return, and a single-family office generally manages without an SFC licence. Bill 2026 broadens the list of qualifying assets — digital assets, private credit, real estate outside Hong Kong; still a bill for now, but with retrospective effect from 2025/26. Conditions and risks are set out in the Hong Kong FIHV article.

The hubs compared

Four hubs in one frame; "—" means the regime simply has no such parameter.

Governance

The working centre of governance is the investment policy statement (IPS): the document in which the family fixes the capital's objectives, the target allocation across asset classes, restrictions, liquidity requirements and authority — who decides, and within what limits. Until there is an IPS, the "strategy" is in practice the manager's memory and the latest thread of correspondence. The document lives in the investment committee — the regular forum where family and office check the portfolio against the strategy; the CIO sets the agenda, delivers the allocation and answers for the choice of managers. The basic division is simple: the family decides the "what and why" — objectives, risk appetite, major transactions; the office executes the "how" — instrument selection, rebalancing, reporting. The minimum configuration of roles:

• investment committee — approves the IPS and deviations from it;
• CIO — answers for the allocation, the managers and the reporting;
• principal or family council — objectives, risk appetite, the office's mandate.

The values layer — who sits on the committee, how family branches vote, what happens when generations change — is fixed one level up, in the family constitution; the IPS is its investment annex.

Succession

The defining challenge of the decade is the "great wealth transfer". Cerulli estimates that by 2048 around $124 trillion will change hands in the United States alone: roughly $105 trillion to heirs and a further $18 trillion to charity. That is why the focus falls on preparing the next generation and formalising governance: without a succession plan both the capital and the office itself lose their footing as generations change.

The instruments are chosen to fit the family: trusts and a Private Trust Company for control and asset protection, private foundations and a family constitution for governance rules, life insurance for liquidity to cover taxes and buy-outs. The family office ties them into a single mechanism and makes sure the documents do not drift away from the actual decisions.

Family office as a service

The classic SFO, with its own staff and a budget upwards of a million dollars a year, is the top end of the spectrum. The family office function is needed by a family long before a dedicated office is economically justified, and it is met by a service model — the outsourced or virtual family office. It works on a hub-and-spoke principle: a single coordinator holds the whole picture, and specialists plug in as the task requires. In our practice this function comes down to three roles.

The first is a single point of entry for financial and legal questions. The family gets one address to which any request is sent: a bank's compliance query on a personal account, a real estate transaction, a tax notice from another jurisdiction, the choice of an investment platform. From there the question is routed to the relevant specialist, but responsibility for the outcome and the deadlines stays at one point. This spares the family the familiar cost of coordinating a dozen advisers who do not talk to one another.

The second is an administrator of legal entities. A family's capital is usually packaged into companies: a family holding, an SPV for real estate or an aircraft, operating businesses, funds and trusts. Each entity has its own calendar of obligations: annual reporting and audit, renewal of registered agents and directors, updating KYC files at banks, UBO registers, substance requirements. The family office keeps this calendar across all the structures at once — the family sees a consolidated picture instead of a stream of letters from registrars in five jurisdictions.

The third is a personal adviser to the principal and the family. Its foundation is accumulated context: the adviser knows the family members' residences and passports, their marriage contracts, their plans for heirs, the history of past decisions. So a new question — a relocation, the sale of a business, a gift — is resolved with the whole picture in view. The longer the family–adviser relationship lasts, the more valuable it becomes: knowledge of the family outlives changes of banks, asset managers and jurisdictions.
