The official name of the Hungarian integrated cadastral system is: unified land registry system. Unified means that the cadastre and the legal registry (“Grundbuch”) have been operating in an integrated form both on legal basis and institutional level since 1971. There is one institutional network consisting of land offices responsible for registration of legal transactions, cadastral mapping changes and dealing with land and other real estate property related activities. Among Europe’s title registry systems, the Hungarian was the first unified one.
