The Land Registry and the Cadastre can both appear in a Spanish property file, but they answer different questions. Comparing them is useful because the home you saw, the rights being sold and the administrative description need to make sense together. A document from one system should not be treated as a complete substitute for the other.
This guide helps you understand the roles, identify the records and recognise when a difference needs investigation. It does not decide a boundary, approve an alteration or determine ownership in an individual dispute. Ask your independent lawyer and any relevant technical professional to explain the actual findings.
Start with the purpose of each record
The Spanish Cadastre's official FAQ describes the Catastro as a “registro administrativo”; our translation is administrative register. Its property descriptions and administrative role differ from the Land Registry's function.
The Registrars' public FAQ explains the Registry's role in recording and publicising ownership and rights over property. Those legal interests are not the same question as every physical characteristic or permitted use.
Think of the records as parts of the investigation. Neither a cadastral map nor a registry extract, taken alone, establishes that every building feature, planning requirement and intended activity has been checked.
Identify the documents rather than using one vague label
A nota simple is commonly used to obtain registry information. Read the nota-simple guide for its purpose and limits. Ask whether your enquiry also needs other registry evidence, a current update or a specific professional explanation.
Cadastral information can include a property reference, descriptive data and mapping. The official Cadastre electronic-services page identifies services for consulting cadastral information. Access and the detail available depend on the service and the information requested.
Keep the document name, issuing body, date and property identifier together. A screenshot forwarded by an agent may help you start an enquiry, but it should not lose its source or be assumed current enough for every purchase decision.
Confirm that the records refer to the home being sold
Ask your lawyer to connect the registry identifiers, cadastral reference, address and physical property. Apartments, garages, stores and other spaces may require separate identification. A familiar building address does not necessarily identify every interest included in the offer.
Walk the areas that matter and compare them with the documentation through the appropriate professionals. If a terrace, enclosed room or outbuilding is central to the purchase, establish its position rather than assuming it is included because it is accessible during a viewing.
Use the private-contract guide to keep the description and included rights accurate in the agreement. The commercial listing and the legal property description serve different purposes.
Treat an area difference as a question to investigate
Figures can differ because of measurement basis, included elements, record history or another reason. Ask what each figure measures before concluding that the difference is harmless or evidence of a serious defect.
A technical professional may need to measure or identify the building and land. Your lawyer can explain the implications for the transaction and any correction route. Do not choose the largest area because it makes the asking price per square metre look better.
For apartments, distinguish usable space, built area, common-element allocation and outdoor areas where relevant. An apparently simple numerical comparison can be misleading when the underlying definitions differ.
Do not assume mapped boundaries settle every right
A map can help locate a plot, but questions about ownership limits, rights of way or access may need additional legal and technical evidence. Explain any intended use that depends on a particular boundary or route.
Ask who owns or maintains the approach and what rights allow you to use it. A track being visible on a map, used during a viewing or described as the normal entrance does not automatically establish the right you need.
For a rural home, read property types and the legal-checks guide. Boundaries, services, land classification and permitted buildings require enquiry tailored to the actual property.
Keep planning and building status as separate checks
The presence of a feature in an administrative description is not the same piece of evidence as the relevant planning or occupancy documentation. Ask the competent authority and advisers what establishes the position for the building and intended use.
If there is an extension, pool, converted space or other alteration, identify what is recorded in each system and which permissions or procedures need investigation. An inconsistency should be explained rather than hidden behind a statement that the house has always looked that way.
The surveys-and-inspections guide explains the technical side of comparing the property with your needs. A technical report and a legal review answer related but different questions.
Ask for the discrepancy to be described precisely
| Question | Useful evidence or explanation |
|---|---|
| What differs? | The exact identifier, area, description, ownership entry or mapped feature. |
| Why does it differ? | A documented explanation, not simply an assurance that differences are common. |
| Who investigates? | The responsible lawyer, technician, registry or cadastral contact. |
| What action is proposed? | The appropriate procedure, documents, likely dependencies and limitations. |
| When does it matter? | Its effect on the contract, lender, intended use or completion timetable. |
Use the table to keep the issue specific. A broad request to make the paperwork match may conceal several distinct tasks with different authorities and evidence requirements.
Understand the proposed correction before committing
The Cadastre's procedures page describes different ways changes enter its records. The suitable route depends on the matter. Do not assume a single form can resolve every discrepancy or alter the legal position elsewhere.
Ask what can be established now, what action is required, who will do it and what outcome remains uncertain. If another person's involvement or an official decision is needed, include that dependency in the timetable.
Where the purchase depends on resolution, discuss the appropriate contract position with your lawyer. An expectation that the buyer can sort it out afterwards is a proposal to assess, not evidence that the risk or cost is insignificant.
Include the lender's requirements where borrowing matters
Provide the relevant findings to the professionals handling the loan. Ask whether a discrepancy affects the lender's documents, valuation, conditions or ability to release funds. A legal explanation acceptable to you does not automatically establish the lender's decision.
Read the finance-conditions guide before relying on expected borrowing. A smaller advance, further document request or delayed decision can affect the purchase even where the broad property description is familiar.
Keep communications aligned so one professional is not working from an old version while another uses a corrected record. Save the evidence of each change and ask whether any related document needs updating.
Track post-purchase changes through to confirmation
Agree who handles registration of the purchase and relevant cadastral administration. Ask whether a communication route covers your transaction and whether another declaration or correction is required. Do not assume every record changes automatically in every case.
Use the first-30-days guide to distinguish submission, a request for more information and the final outcome. Keep receipt references and identify the person responsible for unresolved issues.
A useful purchase file shows how the rights, records and actual home have been checked together. When something differs, the goal is a clear explanation and an appropriate plan before commitment, with evidence of the eventual result retained for ownership and any future sale.
