Roles and responsibilities in the family office

Every family office has an organisational structure, whether or not anyone has written it down. In the early years of many single-family offices, roles emerge organically: a trusted accountant becomes the de-facto chief financial officer, a family member chairs meetings that have no formal agenda, and an investment analyst answers to two principals simultaneously without knowing which one takes precedence. This informal scaffolding can survive while the founding generation is active and relationships are close. It rarely survives the second generation intact.

The cost of ambiguity is not merely operational friction. A 2023 survey by a leading European family business research institute found that role confusion and governance disputes were cited as contributing factors in more than 60 percent of senior family office staff departures. Replacing a chief investment officer or a chief executive typically costs 18 to 24 months of that person's total compensation when search fees, onboarding time, and institutional knowledge loss are included. Against that backdrop, the drafting of a clear role framework is one of the highest-return governance investments a family can make.

A three-layer model for family office roles

The most durable framework for organising family office responsibilities separates roles into three layers: governance, leadership, and operations. Each layer has a different principal, a different accountability structure, and a different rhythm of review. Conflating these layers, for instance by having a family member simultaneously govern and manage, is the structural error that generates the most persistent dysfunction.

Layer one: governance

The governance layer defines the office's mandate, approves its strategy, and holds the leadership layer accountable. In a single-family office, governance is typically exercised through a family council, a board of trustees, or a formal investment committee, depending on the legal wrapper the family has chosen. In jurisdictions such as Luxembourg, the Cayman Islands, and Singapore, the choice of legal structure directly determines who must sit on formal governing bodies and what fiduciary duties attach to those seats.

Governance-layer participants are not managers. Their accountability is to the beneficiaries of the family's wealth, which may include future generations, charitable vehicles, or non-family stakeholders depending on the family's constitution. Their primary deliverables are a written investment policy statement, an approved annual budget for the office itself, a succession framework for the leadership layer, and periodic review of whether the office's mandate remains fit for purpose. A governance body that drifts into operational decisions, approving individual vendor contracts or intervening in staff scheduling, has lost its strategic altitude and will crowd out the leadership layer it is supposed to oversee.

Governance is not the same as control. A family that governs well sets the destination and the guardrails; it does not drive the vehicle.

The governance layer should meet formally at least twice per year, with written minutes and a standing agenda. Terms of reference for the governing body should be reviewed every three years or upon any significant generational transition. Where an independent trustee or external board member sits at this layer, their terms of engagement, including remuneration, indemnification, and conflict-of-interest protocols, should comply with applicable frameworks. In the European Union, for example, where the family office manages discretionary assets on behalf of multiple family branches, the board may need to consider obligations under MiFID II's governance and conduct-of-business rules.

Layer two: leadership

The leadership layer translates governance intent into operational reality. It is typically occupied by a chief executive officer, a managing director, or a director of the family office, and in larger offices may also include a chief investment officer, a chief financial officer, and a chief operating officer. These roles are professional, not familial: even where a family member holds a leadership title, they should be assessed against the same competency standards applied to an external hire.

The written mandate of the chief executive or director is the single most important governance document in a family office below the level of the family constitution. It should specify the scope of authority (what the executive can commit to without board approval and at what financial thresholds), the reporting line (to the family council, the board, or a specific family principal), the performance review cadence (annually, at minimum), and the succession protocol. A mandate that says the director is responsible for "day-to-day operations" without defining boundaries is not a mandate: it is a source of future conflict.

Where the investment function is separated from the administrative function, the chief investment officer's mandate warrants equal precision. Their authority to allocate across asset classes, to engage external managers, and to use derivatives or leverage (in the financial sense, meaning borrowed capital) should be documented in an investment policy statement appendix and reviewed by the governance layer annually. Under the AIFMD framework applicable in EU member states, where a family office manages alternative investment funds, the responsibilities of the designated portfolio manager must be documented and approved before the entity can operate.

The leadership layer's accountability runs upward to the governance layer and downward to the operational layer. A director who confuses governance and operations will fail at both.

Layer three: operations

The operations layer executes the decisions made above it. It encompasses investment analysts, accountants, legal counsel (whether in-house or retained), compliance officers, family office administrators, and, in larger offices, concierge and lifestyle management staff. The operations layer is where most of the office's day-to-day cost resides, and it is where role documentation most often breaks down into informal workarounds.

The most effective tool for clarifying operational accountability is the RACI matrix, which assigns each recurring process a single Responsible party (the person doing the work), a single Accountable party (the person answerable for the outcome), a set of Consulted parties (those whose input is required before the work is completed), and a set of Informed parties (those who receive updates but do not influence the output). Processes that benefit most from RACI documentation include quarterly financial reporting to the governance layer, tax filings under FATCA and CRS where applicable, manager due diligence cycles, and regulatory compliance reviews.

Staffing costs at the operations layer are the largest single operating expense for most family offices. Total staff costs for a professionally run single-family office, including salaries, bonuses, benefits, and employer-side taxes, typically represent 30 to 60 basis points of assets under management, with the range driven by service scope, geography, and the degree to which functions are insourced versus outsourced. A London-based family office with a full in-house investment team, a dedicated tax counsel, and lifestyle management staff will sit at the upper end of that range. An office that outsources investment management to third-party managers and retains a lean administrative team will sit closer to the lower end.

The critical interface: family members in operational roles

One of the most structurally sensitive configurations in a family office is a family member who works within the operations layer, often a next-generation representative who joins the office to learn the business or to pursue a specific investment thesis. This configuration is not inherently problematic, but it requires explicit role definition to avoid two failure modes.

The first failure mode is role inflation: the family member is nominally an analyst but is treated by staff as a proxy principal, creating a shadow accountability structure that undermines the formal hierarchy. The second failure mode is role marginalisation: the family member is placed in a role with no real responsibility as a developmental gesture, which breeds frustration and attrition. Neither outcome serves the family's succession objectives.

Best practice is to treat next-generation family members in operational roles exactly as professional hires: with a written job description, a defined reporting line to the leadership layer (not directly to a family principal), a formal performance review, and an explicit transition plan that outlines what competencies must be demonstrated before any advancement into the leadership or governance layer. This framework aligns with the governance principles articulated in the OECD's 2021 guidelines on family business governance and reflects practice standards observed in Swiss and Singapore family office jurisdictions, where regulators increasingly expect documented organisational structures as part of licensing and registration processes.

Review cadences by layer

Role documentation is not static. Each layer requires a standing review cadence tied to the rhythm of the family's life and the external regulatory environment.

At the governance layer, terms of reference and the family constitution should be reviewed every three years under normal circumstances, and immediately upon a generational transition, a significant liquidity event, or a material change in the family's jurisdiction of domicile. The introduction of BEPS Pillar Two minimum tax rules, for example, has caused a number of ultra-high-net-worth families to revisit the legal architecture of their family offices and, consequently, the governance responsibilities attached to each entity in the structure.

At the leadership layer, individual mandates and the investment policy statement should be reviewed annually, with a formal performance conversation between the governance body and the chief executive. The investment policy statement should also be reviewed whenever asset allocation targets shift by more than ten percentage points in any single asset class, or whenever the office adds a new asset class such as private credit or direct infrastructure.

At the operations layer, RACI matrices and job descriptions should be reviewed annually as part of the performance management cycle. This review is also the appropriate moment to identify roles that have grown informally beyond their documented scope, a phenomenon sometimes called role creep, and to decide whether that scope expansion reflects genuine organisational need or merely the absence of clear boundaries.

Documentation as a governance lever

Families that resist documenting roles often cite trust as the reason: they trust the people involved, so formal documentation feels unnecessary or even insulting. This reasoning conflates personal trust with institutional clarity. A clearly documented role does not imply distrust; it provides a shared reference point that protects both the family and the individual if circumstances change. People leave, priorities shift, and memories of verbal agreements diverge. A written role framework resolves those divergences before they become disputes.

The practical starting point is not a comprehensive organisational redesign. It is three documents: a one-page terms of reference for the governing body, a two-page mandate for the chief executive or director, and a RACI matrix covering the ten to fifteen processes that recur most frequently in the office. These three documents, drafted carefully and reviewed on a standing schedule, address the majority of role-related dysfunction observed in family offices across geographies and asset scales. The investment in drafting time is measured in days. The return, in reduced conflict, lower staff turnover, and cleaner regulatory compliance, accumulates over decades.
