Lex scripta
Lex scripta is a Latin expression that means "written or statutory law". It is in contrast to lex [non scripta], customary or common law. The term originates from the Roman legal tradition. Emperor Justinian divided the lex scripta into several categories:
Lex scripta has a lasting effect that can define a legal tradition for a culture such as that found in the Corpus Juris Civilis, Magna Carta, Tang Code, or a country's constitution.
In the United Kingdom, and later, the United States, Lex Scripta refers to the body of statutory law that amends or changes the common law, especially when effecting common [law marriage] and other customs. Traditionally, English law, up through the 19th century, was divided into Lex non scripta and Lex scripta, with the Magna Carta being the oldest of the latter.
