In the intimate environment of a Family Office, especially in its early stages, stability is often built around people rather than structures. Long-serving executives frequently become trusted confidants to principals and custodians of family wealth. Their value lies not only in what they do, but in what they know, who they know, and especially, how deeply they are trusted by the family.
While everything runs smoothly, this reliance rarely raises concern. Yet, when a trusted executive leaves, whether unexpectedly or through a planned transition, the event can expose vulnerabilities that were previously hidden.
Processes stall, decision-making slows down, and uncertainty ripples through a small, close-knit team.
In a Family Office, the departure of a senior executive is not simply an HR challenge. It is often a stress test of the Family Office’s resilience, governance structures, and ability to sustain continuity beyond individuals.
As a recruitment and consultancy firm that is dedicated to working with Family Offices, in this article, Agreus would like to explore the so-called “Key Person Risk” we see in the industry, and offer a framework to mitigate this risk.
Understanding “Key Person Risk”
Family Offices are often more exposed to the “Key Person Risk”, than larger institutional organisations.
Their operating models are typically lean by design, with a flatter structure and fewer senior roles. As a result, one individual may hold responsibility for investment oversight, key external relationships, and internal decision-making processes simultaneously. In some cases, executives hold overlapping responsibilities across multiple entities, such as serving as CEO of the family’s operating business while also acting as CFO of the Family Office. Over time, these responsibilities tend to expand organically as trust deepens, with the executive becoming increasingly embedded in the day-to-day functioning not only of the Family Office, but of the family itself.
Discretion, loyalty and continuity are highly valued in Family Offices, which means senior executives often remain in place for decades. While this long tenure brings stability, it can also concentrate institutional knowledge, decision authority and relationship capital in a single individual.
When that individual leaves, replacing them is rarely straightforward. In many cases, the role has grown so broad that it ultimately requires two or even three hires to replicate the responsibilities previously held by one person.
The impact of an unexpected executive departure
When a trusted executive leaves, the consequences often extend far beyond the vacant role itself. In the case of a sudden departure, whether due to illness, death or a career move, it would create immediate disruption:
Operational disruption is often the first sign. Day-to-day processes slow or stall as teams struggle to continue without the key individual’s guidance and knowledge. Tasks that once flowed seamlessly begin to require clarification, rework, or escalation.
Decision-making strain soon follows. Bottlenecks emerge as remaining leaders defer decisions or over-rely on a small number of individuals, increasing pressure and risk.
External relationships may also be affected. Banks, advisers, counterparties, and service providers often rely on a single point of contact who understands both the family and the assets. Transitioning these relationships takes time and careful management, particularly where trust has been built personally rather than institutionally.
Investment Performance may be impacted if investment oversight and decision-making are driven by one person.
Financial, tax, and regulatory exposure may be impacted if key knowledge and information are held with one individual.
Perhaps most importantly, there is a cultural impact. In small teams, the departure of a senior and central figure can create uncertainty, affect confidence and morale, and erode trust. Questions about stability, leadership, and future direction may surface, subsequently affecting the operations of the Family Office.
Where Family Offices are most vulnerable
While every Family Office is unique, certain structural weaknesses consistently increase exposure to key person risk.
One common issue we see is the lack of a professionalised governance structure. Our 2025 Global Family Office Compensation Report, created in collaboration with KPMG Private Enterprise, found that 37% of Family Offices still operate without a formalised governance structure in place. In these environments, decision rights, approval mechanisms and escalation paths may be understood informally but not formally documented. When a key executive departs, these implicit structures can quickly break down.
We found that these vulnerabilities are particularly common in early-stage Family Offices, which are often built organically around a small number of trusted advisers. However, as Family Offices grow and evolve, many move through a process of professionalisation. We have previously explored this in the Family Office maturity model; where early-stage Family Offices tend to operate informally, with concentrated responsibilities and limited structural frameworks. As the Family Office matures, governance becomes more defined, roles become clearer, and systems are introduced to distribute knowledge and decision-making authority across the team.
Another vulnerability is the absence of succession planning. Our 2025 Global Family Office Compensation Report found that 49% of the responding Family Offices do not have a succession plan in place for key leadership roles.
Without structured succession planning, even a well-functioning Family Office can find itself exposed when transitions occur unexpectedly. These vulnerabilities are particularly common in early-stage Family Offices that develop organically around a small group of trusted advisers.
Building resilience beyond individuals
As Family Offices grow and evolve, many move through a process of professionalisation.
In our work with clients, we often observe this progression through stages of organisational maturity. Early-stage Family Offices tend to operate informally, with concentrated responsibilities and limited structural frameworks.
Over time, more mature Family Offices introduce:
- Clear governance structures
- Defined leadership roles
- Documented processes
- Distributed relationship ownership
- Structured succession planning
Rather than relying on one individual, resilience becomes embedded within the organisation itself.
Designing a Family Office that can withstand change
The departure of a trusted executive is one of the most significant stress tests a Family Office can face. Strong Family Offices are designed to withstand change without disruption to values, relationships or performance. By investing in governance frameworks, leadership depth and succession planning, families can reduce dependence on any single individual and ensure continuity across generations.
By addressing the Key Person Risk early, principals can ensure their Family Office remains resilient, whatever changes the future brings.
At Agreus we work with Family Offices globally to improve governance structures, review compensation packages, and build a strong team. Contact our team to discuss how we can support continuity beyond individual roles.
