Procedural Law Law and Legal Definition

"Procedure" differs from "substantive law" in that substantive law defines the rights and duties of everyday conduct. Substantive law includes contract law, criminal law, etc.

A procedural system provides the rules for applying substantive law to real disputes. A procedural system provides guidelines as to what information is received by the judge or jury, how that information is to be presented, and what by standards of proof ("beyond a reasonable doubt," "by clear and convincing evidence," "by a preponderance of the evidence") the information will be judged.
