In the Turkish Civil Code, real rights arise with registration. Alt hough their content changes and disappears with registration. Accor ding to this principle, which is called the positive provision of registra tion, every registered right is valid as a rule. Real rights arising from registration gain publicity by being registered in the land registry. The trust of third parties in the land registry, which provides publicity in immovables, is regulated by the Civil Code. Due to this principle, the person who has taken over the immovable or for whom Limited real rights have been established, is not obliged to check the actual status of the immovable, and to examine the compatibility of the registry records with the physical condition. It may be possible for the physical condition of the immovable to eliminate the goodwill, but depending on the situa tion. However, if this issue, which must be examined in every concrete case, can be accepted as “ not showing the care expected from him ac cording to the requirements of the situation”, the claim of goodwill will not be heard. In determining goodwill, the judge should analyze the me asure of care, the rule of honesty, trust in the law, and the balance between interests.
