A civil wrong or wrong is a cause of action under civil law. Types of civil wrong include: * tort * breach of contract, and * breach of trust. Something that amounts to a civil wrong is said to be wrongful. A wrong involves the violation of a right because wrong and right are complementary terms. An 1860 legal ruling stated that: "It is essential to an action in tort that the act complained of should under the circumstances be legally wrongful as regards the party complaining; that is, it must prejudicially affect him in some legal right".
