possession de mauvaise foi

CONT: One remarkable feature of adverse possession in most civil law systems is the distinction made between good and bad faith possession. Generally, prescription periods are longer for the bad faith possessor (mala fide possessor) than for the bona fide possessor.
CONT: An illegal possessor is a person who stole a thing or appropriated a find. In civil law illegal possession is in turn subdivided into possession bona fide and possession mala fide.
