Establishing and Managing a Single-Family Office: Key Considerations

As wealth accumulates across generations, many ultra-high-net-worth (UHNW) families reach a strategic inflection point: the creation of a single-family office (SFO). More than just a financial vehicle, an SFO becomes a centralized hub for investment management, legacy planning, lifestyle coordination, and risk oversight.

But setting up a family office is complex—requiring careful planning, multidisciplinary expertise, and clear long-term vision. In this blog, we outline the essential considerations for launching and operating a successful single-family office.

What Is a Single-Family Office?

A single-family office is a private entity established to manage the wealth and affairs of one family. Unlike multi-family offices (which serve several clients), an SFO is tailored exclusively to the needs, values, and goals of a single family unit.

Functions often include:

• Investment management

• Tax and estate planning

• Philanthropy and charitable foundation oversight

• Succession and education planning

• Legal and risk management

• Family governance and communication

Why Families Create SFOs

1. Privacy and Control: Full discretion over decision-making and data security.

2. Customization: Services designed around specific family values and long-term vision.

3. Efficiency: Consolidated oversight of complex asset structures.

4. Intergenerational Continuity: Educating and involving future generations.

5. Direct Investment Focus: Greater capacity for private equity, venture, and real estate deal flow.

Core Considerations When Establishing an SFO

1. Cost Structure

Operating costs typically range from $1M–$10M+ annually depending on complexity, geography, and staffing. Families should evaluate whether they can justify and sustain this level of overhead.

2. Staffing and Governance

Roles to consider:

• CIO or investment director

• CFO or head of tax/accounting

• Legal counsel or general counsel

• Philanthropy or foundation manager

• Family education and development lead

Establish a family council or board to align stakeholders and formalize decision-making.

3. Technology Infrastructure

• Portfolio management systems

• Reporting dashboards

• Document and entity management

• Cybersecurity and compliance systems

4. Jurisdiction and Legal Structure

Choosing the right domicile affects tax, regulatory, and operational considerations.

5. Mission and Investment Philosophy

Codify the family’s core values, long-term financial goals, and risk tolerance. Determine whether the family will outsource investment management or build in-house expertise.

Key Challenges SFOs Face

• Talent Retention: Finding and keeping high-caliber professionals in a private setting

• Family Alignment: Balancing generational differences and divergent financial goals

• Succession Planning: Preparing heirs and ensuring continuity

• Risk Management: Including reputational, geopolitical, and tax exposure
