Wealth management for ultra-high-net-worth families goes beyond investing—it involves estate planning, tax strategies, philanthropy, and long-term financial governance. For families with $100 million or more in assets, managing these complexities often requires more than a bank or financial advisor.
A single family office (SFO) provides a private, in-house team dedicated exclusively to one family’s financial and personal affairs. This setup ensures full control, privacy, and a long-term strategy tailored to the family’s unique needs.
For those considering whether to establish a single family office, understanding how it operates and the benefits it provides is essential.
What Is a Single Family Office?
A single family office is a privately owned entity that handles all financial, legal, and lifestyle needs for one wealthy family. Instead of relying on external firms, the family builds its own dedicated team of professionals, ensuring customized service, confidentiality, and direct decision-making power.
Why Do Families Choose a Single Family Office?
Full Control – The family dictates financial strategies, investments, and governance.
Privacy & Security – Sensitive financial information stays within the family’s private team.
Long-Term Focus – Strategies are built for intergenerational wealth transfer, not short-term gains.
Tailored Services – The office is structured to align with the family’s financial, business, and philanthropic goals.
Cost Efficiency Over Time – While expensive to set up, an SFO can reduce fees paid to banks, advisors, and fund managers.
A single family office operates as a financial headquarters, integrating investment management, tax planning, estate structuring, and personal services under one roof.
How a Single Family Office Works
A single family office functions as a fully staffed financial institution, working exclusively for one family. While each office is unique, most include a core team of specialists:
Investment Managers – Oversee stock portfolios, real estate, private equity, and alternative investments.
Tax & Accounting Experts – Minimize tax liabilities and manage financial reporting.
Estate & Succession Planners – Structure trusts, wills, and governance frameworks for seamless wealth transfer.
Legal Advisors – Handle contracts, regulatory compliance, and risk management.
Philanthropy Experts – Manage charitable foundations and impact investments.
Lifestyle & Security Teams – Assist with travel, security, and real estate acquisitions.
Some family offices also outsource specialized expertise as needed, combining in-house resources with external professionals for cost efficiency and flexibility.
Key Services Provided by a Single Family Office
1. Investment Management
A single family office develops tailored investment strategies, often diversifying wealth across:
- Public Markets – Stocks, bonds, mutual funds.
- Private Investments – Venture capital, private equity, hedge funds.
- Real Estate & Infrastructure – Luxury properties, commercial assets.
- Alternative Assets – Art, collectibles, cryptocurrency, and ESG investments.
Beyond growth strategies, family offices protect assets through risk management, legal structuring, and long-term financial planning.
2. Tax Optimization
Wealthy families face complex tax regulations, especially when assets span multiple countries. An SFO helps:
- Structure investments to reduce tax exposure.
- Ensure compliance with international tax laws.
- Plan for estate taxes to preserve wealth across generations.
3. Estate & Succession Planning
A key function of a family office is ensuring a smooth transition of wealth by:
- Establishing trusts and legal structures to safeguard assets.
- Creating wills and succession plans that align with family values.
- Preparing the next generation to manage financial responsibilities.
4. Philanthropy & Giving
Many ultra-high-net-worth families prioritize charitable giving and social impact. A family office facilitates:
- Setting up foundations and donor-advised funds.
- Managing charitable donations and grants.
- Aligning philanthropy with family values and social priorities.
5. Lifestyle & Security Management
Beyond financial oversight, an SFO can assist with:
- Private security and risk management.
- Real estate acquisitions and property management.
- Luxury travel, aviation, and concierge services.
- Education programs for younger family members.
This full-service approach ensures that both financial and personal needs are managed efficiently.
Challenges of Running a Single Family Office
While an SFO offers many benefits, it also comes with challenges:
High Operational Costs – Running a family office costs $2 million or more per year in staffing and infrastructure.
Complex Investments – Managing global assets requires expertise in multiple markets, tax laws, and financial structures.
Family Disputes – Differences in financial philosophy across generations can cause conflicts.
Regulatory Compliance – Governments have strict reporting requirements for high-net-worth individuals.
Because of these challenges, some families opt for a multi-family office instead, which provides similar services but shares costs across multiple families.
How Single Family Offices Compare to Other Wealth Management Options
| Wealth Management Model | Who It’s For | Key Services | Customization | Cost |
|---|---|---|---|---|
| Single Family Office | Families with $100M+ in assets | Comprehensive wealth & lifestyle management | Fully customized | High ($2M+ per year) |
| Multi-Family Office | Families with $25M+ in assets | Full-service financial planning | Personalized, but shared resources | Moderate (shared costs) |
| Private Wealth Management | High-net-worth individuals & families | Primarily investment-focused | Limited customization | Lower fees |
For families that require absolute control and privacy, an SFO is the best option. Those seeking cost-efficient alternatives may consider a multi-family office or private wealth management firm.
