Everything you need to know before buying real estate is included in our Spain Property Pack
Spain operates two distinct property registration systems that serve completely different purposes for property owners.
The Land Registry (Registro de la Propiedad) provides legal proof of ownership and protects your rights against third parties, while the Cadastral Register (Catastro) records physical property details and determines your tax obligations. Understanding both systems is crucial when buying Spanish real estate, as they complement each other but serve separate functions in the property ownership process.

The Land Registry provides legal ownership protection while the Cadastral Register handles property taxation and physical descriptions.
Only the Land Registry offers legal protection against third-party claims and is managed by the Ministry of Justice, while the Cadastral Register is administered by the Ministry of Finance for tax purposes.
Aspect | Land Registry | Cadastral Register |
---|---|---|
Main Purpose | Legal proof of ownership and rights | Property description and tax assessment |
Management | Ministry of Justice | Ministry of Finance |
Legal Protection | Yes, protects against third parties | No legal protection |
Tax Function | Not used for taxation | Determines IBI and wealth tax |
Update Frequency | Upon transactions (weeks to months) | Continuous but can lag |
Access Cost | €10-30 for official extract | Free online access |
Priority in Disputes | Takes legal precedence | Administrative use only |


What exactly is the Land Registry in Spain and what is its main purpose?
The Land Registry (Registro de la Propiedad) is Spain's official public database that certifies legal ownership of real estate properties.
This system provides legal certainty about who owns each property and what rights, debts, or charges are attached to it. When you buy a property in Spain, the Land Registry becomes your legal shield against third-party claims or hidden liens that previous owners might have left behind.
The Land Registry serves as the definitive legal record for property ownership disputes and court proceedings. As of September 2025, all property transactions must be registered here to gain full legal protection, making it an essential step in the Spanish property buying process.
Without proper Land Registry registration, your property ownership lacks legal certainty and you could face challenges from creditors or other parties who claim rights over your property.
What exactly is the Cadastral Register in Spain and what is its main purpose?
The Cadastral Register (Catastro) is Spain's technical and administrative record that maps and describes all real estate properties for tax and municipal purposes.
This system assigns every property a unique cadastral reference number and records detailed information about the property's physical characteristics, location, and official value for tax calculations. The Cadastral Register determines how much you'll pay in local property taxes, specifically the IBI (Impuesto sobre Bienes Inmuebles).
As of September 2025, the cadastral value directly impacts your annual tax obligations and wealth tax calculations. The system provides detailed maps showing property boundaries, construction details, and usage classifications that municipal authorities use for urban planning and tax assessment.
Property owners must ensure their cadastral information stays current, as incorrect data can lead to incorrect tax assessments or complications when selling the property.
Who manages the Land Registry, and who manages the Cadastral Register?
The Land Registry operates under Spain's Ministry of Justice through the General Directorate of Registries and Notaries, while the Cadastral Register falls under the Ministry of Finance via the General Directorate for Cadastre.
This separation reflects their different functions: the Ministry of Justice handles legal ownership matters, while the Ministry of Finance manages taxation and fiscal administration. Each ministry has distinct staff, procedures, and objectives for their respective registry systems.
Land Registry offices are typically located in provincial capitals and major cities, staffed by qualified registrars who must approve all property transactions. Cadastral offices operate at local and regional levels, with technical staff who specialize in property valuation and mapping.
Both systems coordinate when necessary, but they operate independently with different update schedules and requirements for property owners.
What kind of information does the Land Registry actually record?
The Land Registry records comprehensive legal information about property ownership, transactions, and encumbrances.
Information Type | Specific Details Recorded | Purpose |
---|---|---|
Ownership Details | Current owner names, ownership percentages, acquisition dates | Legal proof of ownership |
Property Rights | Usufruct rights, easements, right of way, mineral rights | Define legal limitations |
Financial Encumbrances | Mortgages, loans, liens, pending payments | Protect buyers from hidden debts |
Legal Disputes | Court proceedings, seizures, bankruptcy claims | Alert potential buyers to risks |
Property Boundaries | Legal descriptions, measurements, adjoining properties | Prevent boundary disputes |
Transaction History | Previous sales, inheritance transfers, donations | Establish legal ownership chain |
Building Permits | Construction licenses, renovation approvals | Verify legal construction |
What kind of information does the Cadastral Register actually record?
The Cadastral Register focuses on physical property characteristics and administrative data needed for taxation and municipal planning.
This system records detailed measurements of buildings and land, including total constructed area, usable surface area, number of rooms, bathrooms, and specific construction materials used. The register also classifies properties by use type such as residential, commercial, agricultural, or industrial, which directly affects tax rates.
Each property receives a cadastral value based on location, size, age, and quality factors that determine annual IBI tax obligations. The system includes detailed digital maps showing exact property boundaries, neighboring properties, and municipal infrastructure connections.
As of September 2025, the Cadastral Register also tracks energy efficiency ratings, swimming pools, garages, terraces, and any additional structures that impact the property's taxable value. This comprehensive physical inventory ensures accurate tax assessments and helps municipal authorities plan infrastructure improvements.

Which of the two is legally binding when it comes to property ownership rights?
Only the Land Registry provides legally binding proof of property ownership rights in Spain.
The Land Registry entries have full legal force in Spanish courts and provide absolute protection against third-party claims, making it the definitive source for ownership disputes. When conflicts arise between the Land Registry and Cadastral Register information, Spanish law always prioritizes the Land Registry records for legal ownership matters.
The Cadastral Register serves purely administrative and fiscal purposes without any legal binding power for ownership rights. While cadastral information helps determine tax obligations and provides technical property details, it cannot establish or prove legal ownership in court proceedings.
Property buyers must register their purchase in the Land Registry to gain full legal protection, regardless of what the Cadastral Register shows about the property.
Which one is used for tax purposes and how does it affect property owners financially?
The Cadastral Register exclusively determines your property tax obligations in Spain, directly impacting your annual financial responsibilities as a property owner.
Your cadastral value sets your IBI (property tax) payments, which typically range from 0.4% to 1.1% of the cadastral value annually depending on your municipality. For example, a property with a cadastral value of €200,000 in Madrid would generate approximately €1,000-2,200 in annual IBI taxes.
The cadastral value also affects wealth tax calculations for high-value property portfolios and inheritance tax assessments when transferring property to heirs. As of September 2025, Spanish tax authorities use cadastral values as the baseline for minimum property valuations in transaction taxes, preventing buyers from declaring artificially low purchase prices.
Property owners should regularly verify their cadastral information accuracy, as errors can result in overpaying taxes for years or facing penalties for underdeclared property features like swimming pools or extensions.

If I buy a house in Spain, which register protects me against third parties?
The Land Registry provides your exclusive legal protection against third-party claims when you buy a house in Spain.
Once your property purchase is registered in the Land Registry, you gain legal immunity against previous owners' creditors, hidden liens, undisclosed mortgages, or other parties claiming rights over your property. This protection extends to inheritance disputes, business debts, and divorce settlements that might affect the property.
The Cadastral Register offers zero protection against third-party claims, as it only serves administrative and tax functions. Even if the cadastral records show you as the owner, this provides no legal defense in court disputes or creditor actions.
Spanish law requires completing Land Registry registration within specific timeframes after purchase to maintain this third-party protection, making it a critical step in the property acquisition process.
How often are the records in the Land Registry updated compared to the Cadastral Register?
The Land Registry updates occur specifically upon legal transactions and typically take several weeks to months to complete, while the Cadastral Register theoretically updates continuously but often experiences significant delays in practice.
Land Registry updates happen when you buy, sell, mortgage, or legally modify your property, requiring notarial documentation and formal registration procedures. The process usually takes 2-8 weeks depending on the complexity of the transaction and the workload at your local registry office.
The Cadastral Register should update automatically when notaries report new constructions, property divisions, or significant modifications. However, many property changes go unreported for months or years, creating discrepancies between actual property conditions and cadastral records.
As of September 2025, property owners must proactively notify the Cadastral Register about renovations, extensions, or usage changes to avoid tax penalties and ensure accurate records.

What kind of documents or paperwork do I need to file with each one?
Each registry system requires distinct documentation packages that reflect their different purposes and legal requirements.
For the Land Registry, you need:1. Public purchase deed (Escritura Pública) signed before a notary2. Proof of paid transfer taxes (ITP or IVA receipts)3. Municipal capital gains tax payment certificate4. Official identification documents for all new owners5. Registry fee payment (typically €60-300 depending on property value)For the Cadastral Register, you need:1. Property description forms with detailed measurements2. Construction permits for new builds or renovations3. Technical plans and architectural drawings for modifications4. Notarial documentation for ownership changes5. Declaration forms for property improvements or usage changesThe Land Registry requires professional notarial intervention for all submissions, while cadastral updates often accept direct owner submissions for minor changes. Both systems may request additional documentation based on specific property circumstances or complex ownership structures.

If the details in the Land Registry and the Cadastral Register don't match, which one takes priority?
The Land Registry always takes legal precedence when details conflict with the Cadastral Register information.
Spanish courts recognize only the Land Registry as legally binding for ownership rights, property boundaries, and legal descriptions. When cadastral records show different square footage, ownership percentages, or property boundaries than the Land Registry, the Land Registry version governs all legal matters.
However, the Cadastral Register continues to determine your tax obligations regardless of Land Registry conflicts, potentially creating situations where you pay taxes based on incorrect cadastral information while owning property according to Land Registry records.
Property owners should address discrepancies by updating whichever registry contains incorrect information, as ongoing conflicts can complicate future sales, mortgage applications, or inheritance transfers. As of September 2025, many Spanish properties have minor discrepancies between both registries due to incomplete update processes over decades.
How can I check my property in both registers and what does it cost to do so?
Accessing property information from both registries involves different procedures and costs that reflect their distinct administrative structures.
Registry Type | Access Method | Cost | Information Provided |
---|---|---|---|
Land Registry | Online portal or physical office | €10-30 for official extract | Ownership, mortgages, legal charges |
Land Registry | "Nota Simple" (basic extract) | €9-15 online, €3-6 in person | Basic ownership and encumbrance info |
Cadastral Register | catastro.hacienda.gob.es website | Free | Property details, maps, cadastral value |
Cadastral Register | Local Cadastral Information Points | Free or nominal fee | Detailed reports and official certificates |
Both Registries | Professional lawyer/gestor service | €50-150 total | Complete property legal status report |
Land Registry access requires demonstrating legitimate interest, such as being a potential buyer, current owner, or legal representative. The Cadastral Register provides unrestricted public access to basic property information.
