A more thorough explanation:

EXTRA FAMILIAM

Extra familiam is a Latin term that means "outside the family." It was commonly used in historical contexts to refer to the status of a child after forisfamiliation, which is the legal process of removing a child from their family.

• After forisfamiliation, the child was considered extra familiam and had no legal ties to their former family.
• In ancient Rome, slaves were considered extra familiam and had no rights or legal standing within their owner's family.

These examples illustrate how the term extra familiam was used to describe individuals who were not considered part of a particular family unit. In both cases, the individuals had no legal ties or rights within the family and were considered separate from it.
