Civil law is a major branch of the law. In common law legal systems such as England and Wales and the United States, the term refers to non-criminal law. The law relating to civil wrongs and quasi-contracts is part of the civil law, as is law of property (other than property-related crimes, such as theft or vandalism). Civil law may, like criminal law, be divided into substantive law and procedural law. The rights and duties of persons (natural persons and legal persons) amongst themselves is the primary concern of civil law.
