The first chilean mortgages, censuses and ships record implemented by the Regulation of 20 may 1848: El primer registro chileno sobre hipotecas, censos y naves regulado en el reglamento de 20 de mayo de 1848

Rescued by the author of this work, the Regulation on mortgages, censuses and ships of May 20, 1848, turns out to be a key piece in the development of the real estate registration system that Chile will adopt in the future Regulation for the office of the conservatory registry of real estate of June 24, 1857. To study therefore the sources of the Spanish system of registration, the national laws on priority of credits of 1845 and 1854, besides the Regulation on mortgages, censuses and ships of May 20, is of great importance for the reconstruction of the History of the real estate registry in Chile.
