When looking at property information in Spain, catastral terms often cause confusion.
In Spanish, the correct word is Catastro, spelled with a “t”. In English, you may see cadastre with a “d”, but in practice Spanish officials, notaries, and local councils only recognise Catastro. For that reason, at Survey Spain we use the term catastral, as it reflects how the system is used in Spain.
The Catastro Inmobiliario, is the official government register of land and buildings, maintained by the Ministry of Finance. It records physical, geographic, and tax‑related details for every parcel of land and every property, whether urban or rural. When something is described as catastral, it simply means that it relates to this database.
Every property is assigned a Número Catastral, which is a unique alphanumeric code used to identify it in the Catastro. Alongside this, each property also has a Valor Catastral, which is an administrative value used purely for tax purposes. This value is not a market price or sale value and, in many cases, bears little relation to today’s property values because it was calculated many years ago.
For properties on Rustic land, it is quite normal to find more than one catastral reference. One usually relates to the land itself, while another refers to any buildings or constructions on that land. This is a standard situation and does not, by itself, indicate any legal issue.
It’s also important to understand how the Catastro uses the term “urban”. In a catastral context, urban simply means built. It has nothing to do with planning consent or whether a building is legally urbanised, particularly on rustic land.
Finally, catastral plans and records do not confer legal rights. They are not title deeds and they are not land registry documents. Their main function is to support local taxation, which means boundaries, areas, and descriptions may be approximate or outdated. For legal ownership and rights, the land registry and notarised deeds always take precedence.
