The status of being the firstborn child among several children of the same parents. A rule of inheritance at Common Law through which the oldest male child has the right to succeed to the estate of an ancestor to the exclusion of younger siblings, both male and female, as well as other relatives.
n. Latin for "first born," the ancient rule from feudal England (except in the County of Kent) that the oldest son would inherit the entire estate of his parents (or nearest ancestor), and, if there was no male heir, the daughters would take (receive the property) in equal shares. The intent was to preserve larger properties from being broken up into small holdings, which might weaken the power of nobles. It does not exist in the United States.
PRIMOGENITURE. The state of being first born the eldest.
2. Formerly primogeniture gave a title in cases of descent to the
oldest son in preference to the other children; this unjust distinction has
been generally abolished in the United States.
