Prenotation and note as institutes of preservation are at the core of a safe transfer of material rights to immovable property. Prenotation and notation of the order represent two key legal instruments that protect the order of entering the rights into the land register. The essential legal consequences of their entry into the land register are seen as the possibility of entering the right in the prenotated or notated order and in the special status of entries with a worse order. These are the elements, which are characterized by the tangible and disposable legal transactions. The prenotation is defined by the already concluded legal transaction. The note, on the other hand, abstractly draws the usable value into it. These are two conditional main entries. The key moments in their land registry execution will be: first, the moment of entering the prenotation or note and then second, the proposed registration of the right in the prenotated or notated order. The remark of the dispute, the deletion of the action and the exceptional legal remedy, constitute a legally meaningful consequence of the course of the legal proceedings, concerning the material right to immovable property. The preservation of the order is derived from the principle of causality, which requires a valid binding and disposing legal transaction to transfer the material right to immovable property. The prenotation and note are bound between the real and the obligatory law and marked by the land register law, which defines and confines the land registry procedure. What these institutes pursue is preservation against the possibility of acting on the principle of trust in the land register, which gives priority to the status of the land register before the actual status.
