Key Takeaways
- The Registro de la Propiedad is Spain’s Land Registry — it records property ownership, charges, mortgages, and restrictions.
- Registration is not mandatory but strongly advisable — it gives you legal protection against third-party claims and is required for a mortgage.
- The nota simple is the key document — a summary extract showing current ownership, description, and any charges on the property. Cost: EUR 10-15 online.
- The cadastre (Catastro) is separate from the Land Registry — it records physical boundaries and tax values. Discrepancies between the two are common.
- Registration after purchase typically takes 2-8 weeks and costs EUR 400-700 (regulated fees).

Spain has two parallel property records: the Registro de la Propiedad (Land Registry) and the Catastro (Cadastre). They record different things, are maintained by different authorities, and frequently disagree with each other. Understanding both is essential before buying property.
The Land Registry (Registro de la Propiedad)
What It Records
- Ownership: Who owns the property, their share, and how they acquired it (purchase, inheritance, donation)
- Description: Location, boundaries, size (though this may not match reality — more on this below)
- Charges and encumbrances: Mortgages, liens, embargoes, anotaciones preventivas
- Rights: Easements, usufruct, rights of way
- Restrictions: Planning designations, protected status
Why Registration Matters
Land Registry registration is voluntary in Spain — but skipping it is risky:
- Third-party protection: Registration protects you against claims from anyone else. If you buy a property and don’t register, a subsequent buyer who does register takes priority — even though you bought first.
- Mortgage requirement: No bank will lend against an unregistered property.
- Proof of ownership: In disputes, the registered owner has a massive legal advantage.
- Future sale: Selling an unregistered property is difficult — most buyers and their lawyers will insist on registration.
The Nota Simple
The nota simple informativa is a summary extract from the Land Registry. This is the document your lawyer obtains during due diligence. It shows:
- Current registered owner(s)
- Property description and size
- Any charges: mortgages, embargoes, restrictions
- The finca number (unique registry identifier)
How to obtain one:
- Online: registradores.org — EUR 10-15, delivered by email within 24-48 hours
- In person: At the local Registro de la Propiedad — EUR 20-30, available same day or next day
- Through your lawyer: Included in their due diligence (they’ll obtain an updated version before completion too)
Always check an updated nota simple 24-48 hours before signing at the notary. Things can change between the due diligence period and completion — a new charge, an embargo, a court order.
The Cadastre (Catastro)
What It Records
The Cadastre is Spain’s property tax register, maintained by the Ministry of Finance:
- Physical description: Location, boundaries, built area, plot area
- Cadastral value (valor catastral): Used to calculate IBI and other taxes
- Cadastral reference: A unique 20-character identifier for every property in Spain
- Use designation: Residential, commercial, rural, etc.
Land Registry vs. Cadastre: The Discrepancy Problem
Here’s where it gets complicated. The Land Registry and the Cadastre are maintained independently, and they frequently disagree:
- Size: The Registry may show a 120 sqm apartment; the Cadastre may show 115 sqm. Neither may reflect the actual measured size.
- Boundaries: The Registry description may not match the cadastral plan, especially for older properties or rural land.
- Extensions: An owner who added a 30 sqm terrace enclosure may have updated the Cadastre (to avoid higher IBI) but not the Registry — or vice versa.
Why this matters when buying:
- If you’re paying per square metre, which measurement are you using?
- Mortgage valuations are based on the registered size — a discrepancy can affect your loan.
- Unregistered extensions may not be legal (built without licence).
- Tax calculations (IBI, capital gains on future sale) use cadastral values.
Your lawyer should compare the Registry entry, the Cadastre record, and the physical reality — and flag any discrepancies before you commit.
Registration After Purchase
After signing at the notary, your lawyer submits the escritura to the Land Registry for registration. The process:
- Presentation: The escritura is presented to the Registry (can be done electronically by the notary)
- Qualification: The registrar reviews the document for legal compliance. If there are defects, they issue a calificación negativa with reasons — your lawyer resolves these.
- Registration: The property is inscribed in your name
- Timeline: 2-8 weeks from presentation to registration (15 business days is the legal maximum, but delays happen)
Costs
- Registration fees: Regulated based on property value — approximately EUR 400-700 for a standard residential property
- Included in your lawyer’s service: Most property lawyers handle the registration as part of their fee
Special Situations
Inherited Properties
Properties acquired through inheritance must go through the adjudicación de herencia process before they can be sold. If the seller inherited the property, your lawyer should verify that:
- The inheritance deed (escritura de adjudicación de herencia) has been signed and registered
- Inheritance tax was paid (can become a charge on the property if unpaid)
- All heirs agreed to the sale (a property with multiple heirs requires all their signatures)
Rural Properties (Fincas Rústicas)
Rural land has additional complications:
- Minimum plot sizes for building vary by municipality
- Agricultural designations may restrict construction
- Many rural properties have unregistered boundaries or buildings
- The PGOU (municipal urban plan) determines what can be built — this overrides what currently exists

Frequently Asked Questions
What is a nota simple in Spain?
A nota simple informativa is a summary extract from the Land Registry showing current ownership, property description, and any charges (mortgages, liens, restrictions). It costs EUR 10-15 online and is the essential document for property due diligence. Always obtain an updated one before signing at the notary.
Is it mandatory to register property in Spain?
No, but it’s strongly advisable. Registration protects you against third-party claims and is required for obtaining a mortgage. An unregistered property is harder to sell, harder to insure, and legally vulnerable. Your lawyer should handle registration as part of the purchase process.
What is the difference between the Land Registry and the Cadastre in Spain?
The Land Registry (Registro de la Propiedad) records legal ownership, charges, and rights. The Cadastre (Catastro) records physical descriptions and tax values. They’re maintained by different authorities and frequently show different sizes or boundaries for the same property. Both should be checked during due diligence.
How long does Land Registry registration take in Spain?
The legal maximum is 15 business days from presentation, but in practice it takes 2-8 weeks. Complex cases (inheritance, rural land, boundary discrepancies) may take longer. Your lawyer can track the progress.
