The family had $62 million in liquid assets, a closely-held business generating $4 million annually, and three generations with different financial objectives. Their private banker introduced them to seven multi-family offices in six weeks. Each presented compelling credentials. None explained how to distinguish between them. The multi-family office selection process, they discovered, has no standard framework because the industry prefers opacity. Here’s the framework sophisticated families actually use.

The MFO Landscape: Understanding What You’re Choosing

Multi-family offices emerged when single-family offices recognized they could serve additional families while reducing per-family costs. Understanding what a family office is provides essential context for evaluating MFO options. Today, the landscape includes bank-affiliated MFOs, independent advisory firms, accounting firm derivatives, and evolved single-family offices that opened their doors to additional clients.

According to Pennington Partners, MFOs typically accept clients with investable assets ranging from approximately $30 million to $1 billion. The threshold varies by service model, geographic market, and competitive positioning. For families weighing their options, understanding the family office vs wealth management distinction clarifies what MFOs actually provide.

The number of MFOs has expanded dramatically. Industry research indicates the family office count tripled from roughly 1,285 in 2019 to over 4,500 by 2023. This proliferation means more options, but also more variance in quality, service depth, and alignment with family interests.

The Four Capitals of MFO Selection

Economic Capital: Decoding Fee Structures

MFO fees typically range from 0.5% to 2% of assets under management, with lower rates for larger asset tiers. Kiplinger reports that one Zurich-based MFO charges 2% for $5 million, 1% for $10 million, declining to 0.02% for $500 million or more. These graduated structures reward scale while covering operational costs for smaller relationships.

Beyond AUM fees, examine additional charges. Planning services, estate structuring, tax preparation, and specialized consulting often carry separate fees. Some MFOs bundle these services; others bill à la carte. Our comprehensive analysis of family office costs provides benchmarks for evaluating whether MFO pricing represents fair value.

Hidden costs matter equally. Investment management often occurs through proprietary products or affiliated managers. These embedded fees may not appear on MFO invoices but reduce net returns. Ask explicitly: what percentage of my portfolio will be managed by affiliated entities, and what are their fee structures?

Cultural Capital: Evaluating Sophistication Alignment

MFOs vary dramatically in their investment sophistication. Some operate primarily as wealth preservation vehicles emphasizing diversified public market portfolios. Others function as quasi-institutional investors with direct deal capabilities, private equity access, and alternative investment expertise.

Your family’s requirements should drive this evaluation. If your wealth derives from a recent liquidity event and you lack investment experience, an MFO with strong educational infrastructure may matter more than deal flow access. If you’ve managed significant portfolios and seek opportunities unavailable through traditional channels, investment sophistication becomes paramount.

Assess cultural alignment carefully. Does the MFO serve families similar to yours? A firm specializing in multi-generational European industrial families may not understand the dynamics of a first-generation American technology entrepreneur. For those considering whether MFO is the right structure at all, our comparison of single family office vs multi-family office structures helps clarify the trade-offs.

Social Capital: Network and Deal Flow Access

One of the primary advantages of MFO structures is network access unavailable to individual wealth management clients. Evaluate what network the MFO actually provides. Do they facilitate introductions among client families? Can you access co-investment opportunities alongside other clients? Do they maintain relationships that generate proprietary deal flow?

TIGER 21 research notes that co-investing allows family offices to tackle more complex opportunities with reduced risk while building relationships within the family office community. If your MFO doesn’t facilitate these connections, you’re paying for infrastructure without receiving full value.

Geographic network matters too. An MFO concentrated in Silicon Valley may provide excellent technology sector deal flow but limited access to real estate opportunities in the Hamptons. Understand where the firm’s relationships concentrate and whether that aligns with your investment interests and lifestyle.

Symbolic Capital: Reputation and Discretion

The MFO’s reputation affects how counterparties perceive your family. Working with a respected independent firm signals different things than engaging a bank-affiliated platform. Neither is inherently superior, but understand what your choice communicates to those with whom you transact.

Discretion deserves particular scrutiny. How does the MFO handle confidential information? Do they share client lists for marketing purposes? Will your participation become known to other clients or the broader community? For families prioritizing privacy, these questions may override other considerations.

The Selection Framework: Due Diligence Priorities

Ownership and Governance Structure

MFO ownership varies significantly. Some firms remain majority-owned by founding families, ensuring long-term alignment with client interests. Others operate under private equity ownership, which may introduce pressure for growth, fee increases, or eventual sale. Bank affiliations create different dynamics, potentially prioritizing product distribution over pure advisory.

Ask directly: Who owns this firm? How has ownership changed in the past decade? What is the ownership transition plan? Firms that cannot answer these questions clearly may be concealing structures that conflict with client interests. Understanding family office governance principles helps evaluate whether an MFO’s structure supports long-term client interests.

Team Stability and Expertise

Your relationship exists with people, not institutions. Evaluate the team who will actually serve your family. What are their backgrounds? How long have they been with the firm? What is the client-to-advisor ratio? Average MFO account sizes sit in the tens of millions with client-to-employee ratios around 3-to-1. Firms with higher ratios may provide less personalized attention.

Compensation structures affect retention. Firms paying below-market salaries experience higher turnover, disrupting client relationships. Understanding the family office careers landscape reveals what competitive compensation actually looks like. Ask about compensation philosophy without requiring specific numbers. The answer reveals whether the MFO invests in retaining talent.

Investment Capabilities and Access

Map the MFO’s investment capabilities against your objectives. Do they manage investments in-house or outsource to third-party managers? What asset classes do they access directly? Can they execute direct private equity investments, or do they only allocate to funds?

Industry research shows 50% of family offices plan direct investments in private companies. If your MFO lacks these capabilities, you may miss opportunities available to families at competitor firms. However, direct investing requires infrastructure many MFOs don’t possess. Understand the gap between marketing claims and actual execution ability.

Service Scope and Customization

MFOs offer varying service depth. Core offerings typically include investment management, tax planning, and estate planning coordination. Extended services may encompass family governance, next-generation education, philanthropic advisory, lifestyle management, and concierge services.

Determine what you actually need versus what sounds appealing. Paying for services you won’t use increases costs without adding value. Conversely, choosing a firm lacking services you’ll need creates future disruption when you outgrow their capabilities.

The Hamptons Factor: Geographic Considerations

For families with Hamptons presence, evaluate whether prospective MFOs understand the specific dynamics of East End real estate, local estate planning considerations, and the social infrastructure where wealth concentrates seasonally.

Some MFOs maintain Hamptons relationships that facilitate introductions, real estate access, and participation in gatherings like Polo Hamptons. Others operate entirely from urban headquarters with limited East End presence. If your family’s lifestyle centers on Southampton or East Hampton summers, geographic alignment matters for relationship continuity and opportunity access.

Red Flags in the Selection Process

Certain patterns should trigger heightened scrutiny. Reluctance to provide clear fee documentation suggests hidden costs. Inability to articulate how client interests align with firm economics indicates potential conflicts. High advisor turnover signals compensation or cultural problems. Aggressive growth without proportional infrastructure expansion means service quality will deteriorate.

Perhaps most importantly, evaluate how the MFO handles the selection process itself. Firms pressuring rapid decisions, discouraging competitor conversations, or offering unusual incentives for commitment may prioritize their interests over yours. The best MFOs recognize that thoughtful selection produces better long-term relationships.

The Multi-Family Office Selection Decision

Choosing an MFO isn’t selecting a service provider. It’s selecting a partner who will influence your family’s financial trajectory for potentially decades. The decision deserves the same rigor you’d apply to any major business commitment.

Request references from current clients with similar profiles. Conduct background checks on key personnel. Review regulatory filings where available. Meet with the actual team who will serve your family, not just business development professionals.

For families who determine that even MFO structure isn’t quite right, virtual family office arrangements offer a tech-enabled alternative worth exploring.

The sophisticated family recognizes that multi-family office selection determines whether they access the infrastructure wealthy families have used for generations or settle for sophisticated-sounding services that ultimately underdeliver. The difference compounds across decades and generations. Choose accordingly.
