SEC Family Office Rule

The SEC Family Office Rule is the regulation that gives most single family offices a clear path to operate their investment programs without registering under the Investment Advisers Act of 1940. At its core, the rule creates an exemption — not just an exclusion — by defining what a "family office" means for regulatory purposes. Meeting that definition is what allows the office to manage family wealth without becoming a regulated investment adviser.

The rule sets out conditions around who can be served (generally members of a single family and certain closely related parties), how the office must be owned and controlled, and the requirement that the office not hold itself out to the public as an investment adviser. A family office serving only the descendants of a common ancestor and their spouses, for example, commonly fits within the rule's framework — but the precise boundaries require careful legal analysis every time the family's circumstances change.

Families adding new members, onboarding a key employee as a partial beneficiary, or considering serving a related charitable entity need to revisit whether they still qualify. A single misstep can result in the office needing to register as an RIA, which carries significant compliance obligations. This is an area where working with a qualified securities attorney is not optional — it is essential. The rule is one reason why legal entity structure is treated as a foundational decision when building a family office.
