Latin. To die. Persons who die at the same time. Usually this refers to simultaneous death statutes and how the state deals with whether one person died before the other. Under the common law: This Latin word signifies those who die at the same time, as, for example, by shipwreck. When several persons die by the same accident, and there is no evidence as to who survived, the presumption of law is, they all died at the same time.
