Ultimogeniture

Ultimogeniture, also known as postremogeniture or junior right, is the tradition of inheritance by the last-born of a privileged position in a parent's wealth or office. The tradition has been far rarer historically than primogeniture (sole inheritance by the first-born) or partible inheritance (division of the estate among the children).
