Juveigneurie is a succession practice of the nobility or commoners according to the regions.

In Brittany, in the nobility, the juveigneur is a cadet without distinction of order of birth. Article 330 of the Custom of Brittany also says that it is one of the forms of noble holding of lands, as a fief and dependent on faith and homage: "one of the forms of noble holding is the holding of the eldest juvenile in the division and rowing that is the elder vassal, or descendants of him, to his elder brother Lord, or descendants of the said eldest. "

In Alsace, Artois, Flanders and Picardy, juveigneurie is a common practice. The juveigneur is the youngest (son or daughter) who receives all that remains of the family patrimony once his older siblings have settled elsewhere with a "starting patrimony".
