In law, codification is the process of collecting and restating the law of a jurisdiction in certain areas, usually by subject, forming a legal code, i.e. a codex (book) of law.
Codification is one of the defining features of civil law jurisdictions.[contradictory] In common law systems, such as that of English law, codification is the process of converting and consolidating judge-made law or uncodified statutes enacted by the legislature into statute law.[1][2][3]
