A medieval legal process of disinheriting or excluding someone from a family's property and rights, formally removing them from the family structure.
From the Latin 'foris' (outside) + 'familia' (family), with the suffix '-ation' added to create a noun for the legal procedure. This was a recognized process in English common law.
Forisfamiliation was so officially recognized in medieval England that lawyers had a specific term for it—you couldn't just kick someone out, you had to do it legally with witnesses and documents, making it official and permanent.
