The law is pretty basic and most probably you won't find what you are looking for unless you also read the regulations (Reglamento General de Registros de Titulos, Reglamento de los Tribunales Superiores de Tierra y la Jurisdiccion Inmobiliara, Reglamento de Mensura, Reglamento para el controly Reducci?n de Constancias Anotadas) , the enabling legislation, etc. This is certainly not a job for you if you don't read Spanish well AND are not versed in legalese.
