Multi-family office: how a shared office serves several families

What does a multi-family office do for its clients?

A multi-family office gives each client family the core services of a private office: consolidated reporting, investment oversight, adviser coordination, administration and support for decisions. It delivers them from one platform that serves many families, so each family gets a coordinated view without building its own organisation. The family keeps the final say on every decision, and the firm prepares the facts.

The firm acts as the family’s representative toward banks, lawyers and managers. It compares offers, checks that reports match and asks the questions a busy family forgets. A family can use the firm for all functions or for a chosen few, which makes the model flexible as needs change.

How is a multi-family office organised?

Most shared offices organise around client teams. Each family has a lead, often called a relationship manager, supported by analysts, accountants and specialists who also serve other families. Central teams run research, technology, risk and compliance for everyone.

This structure explains the value and the limits. Specialists see many situations and bring pattern knowledge, and the platform keeps costs per family lower than a private team of the same quality. Attention is shared, so the family agrees in writing on response times, meeting rhythm and a named lead.

Which families use a multi-family office?

Families choose a shared office when they want coordination, and a private team looks heavy for the estate. Founders after a business sale, families with assets in several countries and second-generation heirs who inherit complex estates are frequent profiles.

Some families already run a private office and add a shared firm for a specific function, such as reporting or investment research. That mix lets a small team reach specialist depth. In every case the family states the goal first, then picks the functions it wants the firm to own. A clear scope in the agreement keeps both sides aligned from the first month.

What does a multi-family office share across its families?

Families share the technology, research, risk monitoring and operational processes of the firm. A single reporting system produces consolidated statements for each client. A single research team studies markets, managers and structures, and a single compliance function applies the same standards across the book.

Information about each family stays separate. Strong firms enforce access controls, confidentiality rules and separate records for each client. Ask how the firm applies these controls and how it handles requests from regulators and auditors, since the answers show how seriously the firm treats privacy.

How does a multi-family office charge its families?

Firms charge in several ways: a percentage of assets, a fixed retainer, an hourly rate, a fee per service, or a mix. Each method rewards different behaviour, so the way a firm charges tells you where its attention goes. The multi-family office fees page compares these methods in detail.

Ask for the full fee schedule in writing, with every item that a family pays, including fees at the level of products or managers. A clear schedule lets you compare firms on equal terms and calculate what you will pay under several scenarios. Price comparisons need the same scope, so list the functions first, then ask each firm to quote against that list.

How does a multi-family office manage conflicts of interest?

Conflicts arise when a firm earns from products it recommends, from affiliated banks or from other relationships. Good firms disclose these links, set rules for recommending products and explain how they select managers. Disclosure by itself helps, and independence in practice helps more.

Ask the firm how it is owned, who benefits when you buy a product and how it handles two clients with opposing interests. Plain answers signal maturity. A firm that offers a written conflicts policy and explains it in simple terms earns more trust than one that gives general assurances. Ask also for examples of how a past conflict was resolved.

How can a family choose a multi-family office?

Choose on fit, evidence and terms. Fit means the firm understands families like yours. Evidence means references, track record in coordination and clear reporting samples. Terms mean fees, service levels and exit conditions. The page on how to choose a multi-family office lists 10 questions to put to every candidate.

Meet at least 3 firms, use the same question list for each and score the answers. Keep the scores and the reasons in a short table. A written comparison helps the family agree internally and gives you a record to review when the first year ends.
