Single Family Office Structure: Roles and Hiring Sequence

Single Family Office Structure: Roles and Hiring Sequence

The single family office is the most private, most bespoke, and least standardised entity in the professional wealth management landscape. No two SFOs are structured identically — because the family’s wealth, governance preferences, investment philosophy, and generational composition are different in every case, and the office structure should reflect all of them. What is consistent is the challenge of building an effective professional team: identifying the right functions to internalise, hiring the right sequence of people, and establishing the governance framework that allows the office to operate coherently over the long term.

This guide is written for UHNW principals, family council members, trustees, and advisers who are building, structuring, or reviewing a single family office. It covers the core functions a single family office typically needs, the sequencing of professional hires as the office grows, the governance framework that underpins an effective SFO, and the common structural mistakes that families make and how to avoid them. It draws on the experience of running senior executive searches for single family offices across the full size range — from newly established SFOs making their first professional hire through to mature multi-hundred-million pound offices restructuring their teams for the next generation.

What a single family office actually is

A single family office is a private entity — typically a company, a partnership, or a trust structure — established by a high or ultra-high-net-worth family to manage its wealth, investments, and associated activities on an integrated and confidential basis. The defining characteristic of the SFO is exclusivity: unlike a multi-family office, which serves multiple client families as a financial services business, the SFO exists solely for one family. Every professional within it works for that family’s interests alone.

The threshold at which a family office becomes economically viable as a separate structure is typically cited in the £50m–£100m net wealth range, though this varies considerably with the complexity of the family’s financial affairs and their preference for integrated professional management over external adviser relationships. The Campden Wealth Global Family Office Report estimates over 3,000 single family offices are active in the UK, managing combined assets well in excess of £1 trillion. The distribution of that population is heavily skewed: most SFOs manage assets in the £50m–£500m range, with a smaller number of very large SFOs managing multi-billion pound portfolios.

The core functions of a single family office

A fully developed single family office typically performs five distinct functions, each of which requires dedicated professional resource above a certain scale of activity.

Investment management is the primary function in most family offices — overseeing the investment of the family’s financial assets, whether through external manager allocations, direct investments, or a combination. The investment function is led by the CIO and, at larger offices, supported by one or more Investment Directors or senior investment professionals.

Financial management and reporting covers the consolidated financial reporting of the family’s wealth across all its entities and investments, tax management and compliance, treasury management, and the family’s external banking and lending relationships. This function is led by the CFO and is often the first genuinely specialised professional function a family internalises, because the complexity of consolidated reporting across multiple structures typically exceeds what a family’s external accountants can manage effectively.

Operations and governance covers the infrastructure within which the office functions: technology systems, reporting platforms, custody and administration relationships, external service provider management, risk management, compliance, and the governance processes — investment committee meetings, family council meetings, trustee meetings — that give the office its institutional discipline. This function is led by the COO or, at smaller offices, by the Family Office Director.

Legal and trust management covers the legal structures within which the family’s wealth is held — trusts, holding companies, partnerships, and their associated legal, tax, and regulatory obligations — alongside the management of the family’s external legal relationships and the oversight of significant legal transactions. This function is often handled through external legal advisers supplemented by an in-house legal resource at larger offices.

Family governance is the function that distinguishes a family office from a private investment company — the management of the family’s internal governance: the family constitution, the family council processes, the next-generation education and development programmes, the succession planning framework, and the philanthropic strategy. This function is most often managed by the Family Office Director or an equivalent senior generalist, sometimes with external family governance advisory support.

The hiring sequence — what to build in what order

The sequence in which a family internalises professional functions is one of the most consequential decisions in the early life of a single family office. The right sequence is determined by the family’s specific situation — the nature and complexity of their wealth, the degree to which they currently rely on external advisers, and the investment mandate they intend to pursue — but some principles apply broadly.

Stage one: the generalist senior professional. Most families establishing or professionalising a single family office should appoint a senior generalist as their first internal hire — a Family Office Director or equivalent who can build the infrastructure, establish relationships with external advisers and service providers, create the governance framework, and coordinate the activities of the principal and the office before any specialist function is internalised. The Family Office Director who joins a well-established network of external advisers and a clear governance framework can add value immediately; the CIO who joins a structureless environment will spend their first months building what should have existed before they arrived. See our Family Office Director Recruitment page.

Stage two: investment leadership. Once the operational and governance infrastructure is in place, the investment function can be internalised effectively. The CIO who joins an office with clear reporting lines, an investment committee structure, and an agreed investment policy statement can focus on the investment mandate rather than the infrastructure. At this stage, the external investment advisers and managers the family has been using may be retained alongside or transitioned as the CIO develops a direct investment capability. See our Family Office CIO Recruitment page.

Stage three: finance and operations. As the office grows and the complexity of the consolidated financial picture increases, dedicated CFO and COO functions become separately necessary. At smaller offices, these functions may be combined with the Family Office Director mandate for several years. The trigger for separating them is typically when the financial reporting, tax compliance, or operational management workload exceeds what a generalist can effectively manage alongside the governance and principal relationship responsibilities of the Family Office Director role. See our Family Office CFO Recruitment and Family Office COO Recruitment pages.

Stage four: specialist investment support. At larger offices with direct investment programmes or complex multi-asset allocations, the CIO will require dedicated investment support — an Investment Director or senior investment analyst who can own the manager research, due diligence, and monitoring process. This hire typically follows the CIO by two to three years and is triggered by the CIO’s workload reaching the point where they cannot maintain the quality of the investment process without assistance. See our Family Office Investment Director Recruitment page.

Stage five: governance and compliance. As regulatory obligations increase — particularly where the family office holds FCA authorisation or manages assets subject to HMRC’s increased scrutiny of family structures — dedicated compliance and risk resource becomes necessary. See our Family Office NED Recruitment page for the governance appointment that often accompanies this stage.

Governance frameworks for single family offices

The governance framework is the invisible infrastructure that determines whether a family office functions as an institution or as an informal arrangement between a principal and a group of professionals. The families that build effective governance frameworks early — before they are strictly necessary — consistently produce better investment outcomes, smoother succession transitions, and more durable professional team relationships than those that allow governance to develop informally.

A well-designed SFO governance framework covers four elements. The investment policy statement defines the family’s investment objectives, risk tolerance, asset allocation framework, and the constraints within which the investment function operates — setting the context within which the CIO works and providing the standard against which investment performance and strategy is evaluated. The investment committee provides the oversight structure for investment decision-making — defining who has authority to make which decisions, how often the committee meets, what reporting it receives, and what decisions require committee approval versus CIO discretion. The family council is the family governance body — the forum in which family members engage with the office on strategic, governance, and succession matters. Its terms of reference, membership criteria, and decision-making authority should be documented before the office is formally established. The trustee and advisory board structure provides independent oversight and challenge — either through trustees (where the family’s wealth is held in trust structures) or through an advisory board with an independent NED element. See our Family Office NED Appointments Guide for more on this dimension.

Common structural mistakes

Internalising functions too early. A family office that internalises investment management before the operational infrastructure is in place, or that appoints specialist professionals before the governance framework exists, creates an environment in which those professionals cannot perform effectively. The cost of hiring the right person into the wrong structure is not just the recruiment fee — it is the time lost, the professional’s frustration, and the relationship damage that a failed appointment creates.

Replicating the adviser relationships without transitioning them. Some families establish an internal family office while maintaining the full suite of external advisers unchanged — which creates duplication, confusion about decision authority, and a professional environment in which the internal team cannot establish credibility. The internalisation of a function should be accompanied by a deliberate transition of the relevant external relationships.

Under-resourcing the Family Office Director role. The Family Office Director is the individual who holds the entire structure together — managing the principal, coordinating the professional team, maintaining the governance framework, and ensuring that the office functions coherently. Under-resourcing this role, or combining it with a specialist function that consumes the incumbent’s available time, is the most common single structural mistake in family office development.

Neglecting succession planning for key professionals. Single family offices are highly dependent on key individuals — the CIO whose investment relationships span decades, the Family Office Director who is the principal’s most trusted professional, the CFO who holds the consolidated financial picture in their head. Planning for the succession of these individuals — not just through emergency planning but through deliberate knowledge management and relationship development — is a governance responsibility that most family offices address too late.
