Referencia catastral

Twenty-character alphanumeric code that the Cadastre assigns to every property, identifying it unequivocally: where it is, its surface area and its attributed use. It appears on the IBI receipt and in the deed, and anyone can use it at the Cadastre's online office to look up the property's physical data. When buying, check that the cadastral reference matches the registered plot being purchased: the Cadastre and the Land Registry are separate bodies and their data do not always agree (different surface areas, undeclared extensions, boundaries). Spotting the discrepancy before signing allows it to be corrected through the rectification procedure and avoids problems when reselling, mortgaging or inheriting.
