This text deals with a phenomenon of transformation of law through one of its essential modalities of existence: writing. Legal texts are not only written by legislators or bodies entitled to make legal rules, but also by jurists in their daily activities: interpretation, plead, council, teaching, decision... The texts written by jurists are, for a part, intentionally descriptive. They mean to be an indication of legal rules, accordingly to the structure of rule of law within which jurists do not have power to make law. But in spite of such a descriptive intention, the written descriptions of law accomplish a transformation of it—this is a change of its form. This phenomenon of transformation is what is called ‘descripture of law’ in this article. It means the continuous realization of legal order through jurists’ writings.
