The Tovačov lawbook is one of the most important sources of the Moravian provincial law in the 15th and 16th century. It has never been printed but it was spread only by numerous manuscripts. This lawbook was published in two editions in 1858 and 1868. Legal historian F. Čáda made an analysis of manuscripts in the end of 1960s.

It is a part of convolute together with prints of Moravian Provincial Code of 1516 and Bohemian Vladislaus Provincial Code of 1500. New manuscript belongs to the Olomouc group of manuscripts of Tovačov lawbook and it is analysed in the context of other known manuscripts.
