Definition of Ex Delicto
From a delict, tort, fault, crime, or malfeasance. In both the civil and the common law, obligations and causes of action are divided into two classes those arising ex contractu (out of a contract), and those ex-delicto. The latter are such as grow out of or are founded upon a wrong or tort, e.g., trespass, trover, replevin. See also Ex contractu. Where cause of action arises from breach of a promise set forth in contract, the action is “ex contractu”, but where it arises from a breach of duty growing out of contract, it is “ex delicto”. Eads v. Marks, 39 Cal.2d 807, 249 P.2d 257, 260.
