The formation of academic Scots law is the major expression of the reception of Roman law in Scotland. And Institutional Writings are the essence of academic Scots law. The birth and evolution of Institutional Writings is the central clue of the formation of academic Scots law. The reception advances gradually through the development of Institutional Writings. At last through legal education and practice we find that the academic Scots law becomes the centre of legal system. Though there are several traits in the reception of the Roman Law in Scotland, its essence, academicization of legal system, is identical with that of the Reception in continental Europe.
