Spain's Catastro and the Land Registry: what each one does

Registro de la Propiedad and Catastro compared

The Registro de la Propiedad records the legal position of a registered property, known as a finca (registered property). It shows the registered owner or owners, the share held by each person, how and when they acquired the property, and registered charges such as mortgages, embargos (seizures for debt), easements, usufructs and annotations of lawsuits.

The Land Registry belongs to the Ministry of Justice system and is run by registradores (registrars). Every registered property falls under one specific registry office. Larger municipalities may have several offices, while a small town may be served by a registry based in another town.

The Catastro is a separate physical and tax inventory of real estate. It contains information such as the property boundaries, surface area, type, cadastral value and cadastral reference. It does not establish legal ownership and does not show mortgages, debts or other registered charges.

This distinction is essential. A person named in cadastral information is not necessarily the person currently registered as the legal owner. Conversely, the Land Registry description may not reflect every physical change recorded in the Catastro.

• Registro de la Propiedad: legal ownership, acquisition details and registered charges.
• Catastro: physical description, boundaries, surface area, cadastral value and tax identification.
• Land Registry record: obtained through a nota simple or, where certification is required, a certificación registral.
• Cadastral record: obtained through a certificación catastral or consulta catastral, meaning a cadastral certificate or query.

What documents do the two systems provide?

The usual Land Registry document is the nota simple, formally called a nota simple informativa. It is an informative extract issued for one registered property. It reflects the registry records on the date of issue and is commonly used for checks before buying, inheritances, dealings with banks, and work involving notaries or lawyers.

A nota simple is not a certified document. A certificación registral (registry certificate) is a different document and is slower and more expensive. The nota simple is nevertheless the document generally used to review who is registered as owner and which charges appear against the property.

The Catastro provides cadastral information through a certificación catastral or consulta catastral. This concerns the physical and tax record rather than the legal title. It can help identify the property, but it cannot replace a nota simple when you need to check ownership, mortgages, embargos or other charges.

Both records can be relevant to the same property, but they answer different questions. Cadastral information describes and identifies it for physical and tax purposes. Registry information shows its recorded legal position.

What is the 20-character cadastral reference?

The referencia catastral (cadastral reference) is a 20-character identifier assigned to a property in the Catastro. You can find it on the IBI property tax bill and in the escritura (deed).

The cadastral reference is useful when requesting a nota simple because it can help locate the correct property and distinguish it from others with a similar address. This is especially important in apartment buildings, developments, rural areas and municipalities divided between several registry offices.

However, the cadastral reference does not turn the Catastro into proof of ownership. The nota simple still comes from the Registro de la Propiedad. The reference is a search and identification aid, not a substitute for the legal registry record.

An address alone may not identify one registered finca. Street names, numbering and development names can also differ between documents. Cross-checking the address and cadastral reference can reduce the risk of submitting a request against the wrong property or registry.

Cadastral value is not market value

The valor catastral (cadastral value) is the value recorded in the Catastro as part of its tax information. Market value is a separate concept connected with the price of a property on the market. The two should not be treated as interchangeable.

A cadastral record therefore does not tell you what a buyer should pay, just as it does not confirm who legally owns the property or whether a mortgage is registered against it. For ownership and charges, you need the Registro de la Propiedad. Questions about how a value affects a particular transaction should be checked with your notary or lawyer.

Why Catastro and Registro records can disagree

The Catastro and the Registro de la Propiedad are maintained for different purposes, so their descriptions do not always match. Differences may concern the address, surface area, boundaries or even the plot identified.

An extension or swimming pool may not be reflected consistently in both records. A plot may have been divided, combined or described differently. Physical changes and the registered legal description can therefore develop separately.

Registration in the Registro de la Propiedad is generally voluntary in Spain, except for mortgages. After a purchase or inheritance, registering the new owner is strongly advisable and is needed in practice if the property is later sold or mortgaged, but the registry record may not always have been updated.

These mismatches are also a common reason why a request is returned because the data is incorrect or the property cannot be found. A cadastral reference may point to physical property information without clearly identifying the corresponding registered finca.

Why the difference matters when buying

When considering a purchase, cadastral information can help you compare the apparent property, its boundaries and its recorded surface with the available documents. The nota simple lets you check the registered ownership and the charges attached to the finca.

Review the names, property description, surface area, address and plot details across the nota simple, cadastral information and deed. A difference does not by itself explain what happened or how it should be handled, but it should not be ignored. Your notary or lawyer can advise on a discrepancy in the context of the proposed purchase.

The most important point is that one record cannot replace the other. A clear Catastro entry does not confirm that the seller is the registered owner or that the property is free of charges. Equally, the Land Registry description may not provide a complete picture of physical changes visible at the property or recorded in the Catastro.

How to obtain a nota simple

Notas Registrales España is a private, independent service. We are not the Registro de la Propiedad, the Colegio de Registradores, a government body or a law firm, and we do not provide legal advice.

To order, provide the property address or cadastral reference, the town, province and your email address. The owner's name is optional but can help where the address is ambiguous. No Spanish DNI or NIE is required to place the order.

We identify the competent registry and cross-check the Catastro and the registry's maps before submitting the request through the official registry platform. The nota simple is issued in Spanish as a PDF and usually arrives by email within 24–48 hours on working days. Weekends and Spanish public holidays can add time.

The total price is €35.86 per property, including our service fee and the official registry fee. You can also request the same document yourself through the official website, sede.registradores.org, for the official fee, which costs less than our service. The official process is in Spanish and requires the correct registry and property details.
