Cautio Muciana Law and Legal Definition

Cautio muciana is a Latin term which means ‘security introduced by Mucius Scaevola.’ It applied to the case of testamentary conditions, which prevented a heir or legatee from doing certain acts. If such prevented acts are done, then the heir or legatee would deprive the hereditas or the legacy. Hence, it means the security given by an heir or legatee to receive immediate possession of a conditional inheritance.
