“The land register consists of the main register ("Hauptbuch") and the collection of documents; the land registry file ("Grundbuchsmappe"), the record of landowners and landed properties contain auxiliary information. In the main register, each property has its own entry (organised by entry numbers, "Einlagezahl", "EZ"), which consist of 3 folios: folio A ("A-Blatt", property particulars), folio B ("B-Blatt", property owner(s)), folio C ("C-Blatt (encumbrances on the property). The collection of documents contains all the documents that served as basis for the registration of a landed property.”
