effects of land registration on validity of juridical acts (emphasis on functions of land registration system)

guaranty of security of juridical act about lands is an important difficulty in every country. disregarding the independence of land registration system from the system of civil law –in enactment, interpretation and amendment of the land registration rules- and disregarding bases and functions of land registration system has resulted in some mistakes made by judicial doctrine and precedent in order to propose proper suggestions for solving the problems related to land registration system and to sanction for juridical acts about lands. however, presentation of every solution in this scope must be proper regarding protective bases of owner and third parties and two functional characters of the land registration system including “informing” and “protective” features. on this basis, land registration systems can be divided into constitutive registration system and confirmative one. this classification means land registration in any case, plays a very effective role in credit of judicial act about land although the degree of this effect is different depending on the system.
