Family Office

A family office is a private organisation that manages the wealth and affairs of one very wealthy family, or of several. It handles investments, tax, estate planning, philanthropy and administration, and is controlled by the family it serves.

Also called: family offices · single-family office · multi-family office · SFO · MFO

A single-family office works for one family and is typically justified only above several hundred million dollars of assets. A multi-family office serves a number of families and spreads the cost. Either may employ its own investment staff or allocate to outside managers.

Because the money is the family's own, a family office has no outside investors to answer to each quarter. It can hold illiquid assets for decades, which is why family offices are prominent buyers of private companies, real estate, farmland and timberland. In the United States a single-family office that meets the conditions of the SEC's family office rule is excluded from registration as an investment adviser.

For banks and payment firms a family office is a demanding customer to onboard. The structures usually involve layers of holding companies, trusts and foundations in several jurisdictions. A provider must identify the ultimate beneficial owners, establish source of wealth as well as source of funds, and check for politically exposed persons among family members.

In practice

A family office that advises or manages money for people outside the family may need a licence. The exemption depends on who the clients are, not on what the firm calls itself.
