Feudum Antiquum Law and Legal Definition

Feudum antiquum is an ancient fee or a fee which a person inherited by descent from his ancestors.

According to the doctrine of the feudists, interests in land were divided into but two kinds, feuda antiqua and feuda nova, which are defined to be those to which the possessor succeeds as heir to his ancestor and those which he has acquired in some other way.
