Family offices are consistently mis-served by financial-services firms that treat them as large private-client relationships. They are not. A family office is a business with governance, staffing, third-party service providers and a written investment policy — and it needs to be advised, banked and administered as one.
The landscape in 2026
The single- and multi-family-office population has continued to grow, driven by first- and second-generation wealth transitions in Asia and the Middle East and by regulatory support in Singapore, Dubai, Abu Dhabi and Hong Kong. Singapore's Section 13O/13U regime, the DIFC and ADGM family office frameworks, and the UAE's federal Family Business Law together define a landscape where family offices operate as regulated or semi-regulated entities with real institutional profile.
Why "private client" thinking fails
Three structural differences:
- Governance. A family office has a board, an investment committee, and — usually — non-family professional staff. Decisions are minuted. A "private client" wealth-management relationship assumes a single ultimate decision-maker.
- Scale. Deal sizes are institutional. A family office asked to write a €25m allocation should see institutional pricing, custody and reporting — not retail-plus.
- Cross-generational planning. The office exists to serve a family for decades, across succession events, marriages, tax-residence changes and generational hand-overs. Solutions have to be portable.
Banks and advisers who miss this either overcharge, under-service, or offer products that fit their private-client shelf rather than the family's actual mandate.
What a properly served family office looks like
- Institutional custody with segregated accounts, independent reporting and access to the bank's institutional trading desks.
- Independent investment reporting — a consolidated view across custodians in one system, not four separate bank statements.
- A written IPS (Investment Policy Statement) that the board reviews annually, with defined asset-allocation ranges and liquidity requirements.
- Governance discipline — quarterly IC meetings, written minutes, conflict-of-interest register.
- Professional staff — a CIO or head of investments, a controller, and often a general counsel or head of operations. Even single-family offices typically run four to eight people at scale.
- Regulated status where required — Singapore VCC/13U, DIFC/ADGM family office designation, Hong Kong SFC Type 9 for external mandates.
Common failure modes
- Running the family office out of the operating business's finance team. Works for a year; fails on succession and on any regulator's inspection.
- Using retail-priced structured products where institutional pricing was available. Cumulative cost drag over a decade is often multiple times the office's operating budget.
- No IPS. Every investment decision becomes an argument.
- Founder as sole decision-maker with no documented delegation. On incapacity or death, the office freezes.
How we approach this at Sovereign Signal
We help families set up single-family offices where the wealth and complexity justify it (typically €100m+), and we help smaller families use multi-family-office platforms where they don't. We design the governance, the investment policy, and the service-provider stack together, and we introduce the specialist custodians, administrators and legal counsel who serve family offices institutionally. We don't sell products and we don't take custodian commissions — the recommendations are structural, not commercial.
Worked example
A €400m single-family office in Europe was using a private-bank platform with four separate custodian relationships, no consolidated reporting, and an IPS written seven years earlier. We ran a three-month review: consolidated custody to one prime with two backup banks, installed an institutional reporting layer, rewrote the IPS with the family board, and hired a CIO. Annual custody and admin costs fell by 35%; investment performance transparency improved dramatically.
FAQs
What's the minimum size for a single-family office?
Practically, €100–150m of investable assets. Below that, a multi-family office or specialist wealth-management platform is usually more efficient.
Where should a new family office be based?
Depends on the family's residence and time zone. Singapore, Dubai, Abu Dhabi, Zurich, Geneva and London each have real merits.
Does the office need to be regulated?
If it only serves the family, usually not directly — but the jurisdiction may require registration or licensing (Singapore 13O/13U, DIFC/ADGM). Serving third parties triggers full licensing.
How many people do family offices actually employ?
A €200m office typically has four to six full-time staff; a €1bn office has fifteen to thirty.
