Procedural law is distinguished from Substantive Law, which creates, defines, and regulates the rights and duties of individuals. Federal constitution, statutes, and judicial decisions form the basis for substantive Civil Law on matters such as contracts, torts and probate. Procedural law prescribes the methods by which individuals may enforce substantive laws. The basic concern of procedural law is the fair, orderly, efficient, and predictable application of substantive laws. Procedural guidance can be found in court rules, in statutes, and in judicial decisions.
