The Tavolare system of public real estate is an unique, but important, institution derived from the Austro-Hungarian legislation which remained in force in the provinces of Trento, Bolzano, Trieste, Gorizia and in some municipalities in the provinces of Udine, Brescia, Belluno and Vicenza.
It is certain that since the first half of the fourteenth century the institute showed those legal principles that are still valid today at the foundation of modern land registry law. We know in fact that at that time Bohemia possessed a collection of customs concerning the public registers, in which all the deeds of constitution and variation of real rights had to be entered, and that registration was not granted except on the basis of proof of validity of the title, as well as the legitimacy of the right of the assignor (e.g. seller, donor, etc.). At the same time, the fundamental principle was introduced according to which registration is not a simple proof but a "substantial" requirement for the purchase and transfer of property and real rights over real estate.
Gradually, the principle extended to neighboring regions, until it was accepted by the Austrian universal civil code in 1811, which made it mandatory for all provinces of the Empire, then regulating the institution with the general law of 25 July 1871 B.L.I n. 95, law recalled with changes in our legal system by the R.D. March 28, 1929, n. 499. The Tavolare Law is therefore a set of rules having the character of special law, in force in the territories already subject to the Austro-Hungarian Empire and annexed to Italy after the First World War, which prevails over the common Civil Law, if incompatible with this .
