Entry type: Ranking category

Field: Private Wealth

Definition

Independent Multi-Family Offices are privately owned or partner-led organizations serving multiple wealthy families without control by a bank, insurer or large product manufacturer.

Overview

The shared model can offer broader capability and lower fixed cost than a single-family office. Independence, however, must be tested through ownership, revenue sources, product relationships and custody. Service depth varies from investment-led advisory to highly integrated governance, fiduciary and administration platforms.
