Louisiana law

Law in the state of Louisiana is based on a more diverse set of sources than the laws of the other forty-nine states. Private law—that is, substantive law between private sector parties, principally contracts and torts—has a civil law character, based on French and Spanish codes and ultimately Roman law, with some common law influences. Louisiana's criminal law largely rests on American common law. Louisiana's administrative law is generally similar to the administrative law of the U.S. federal government and other U.S. states. Louisiana's procedural law is generally in line with that of other U.S. states, which in turn is generally based on the U.S. Federal Rules of Civil Procedure.

The Louisiana Revised Statutes (R.S.) contain a very significant amount of legislation, arranged in titles or codes. Apart from this, the Louisiana Civil Code forms the core of private law, the Louisiana Code of Civil Procedure (C.C.P.) governs civil procedure, the Louisiana Code of Criminal Procedure (C.Cr.P.) governs criminal procedure, the Louisiana Code of Evidence governs the law of evidence, and the Louisiana Children's Code (Ch.C.) governs family law and juvenile adjudication.

The Louisiana Administrative Code (LAC) contains the compilation of rules and regulations (delegated legislation) adopted by state agencies. The Louisiana Register is the official journal of regulations and legal notices issued by the executive branch.
