1. Why Registry–Cadastre discrepancies matter
One of the most common issues in Spanish real estate transactions —whether in a purchase, inheritance or change-of-use process— is the difference between the Land Registry (Registro de la Propiedad) and the Cadastre (Catastro).
These Registry–Cadastre discrepancies may look minor, but in practice they can block a sale, delay mortgage approval, or lead to ownership and tax inconsistencies.
Since the Law 13/2015 of June 24, Spain has implemented the Land Registry–Cadastre coordination system to unify the legal and physical reality of every property.
👉 If your property is not coordinated, the Registry and Cadastre may show different surface areas, boundaries or shapes, causing conflicts in transactions, licenses or inheritance proceedings.
2. When is coordination mandatory?
As of 2025, coordination is not mandatory in every case, but it is required in specific situations, such as:
- When creating new properties (segregations, groupings, reparcellations).
- In inmatriculations or corrections of surface.
- In notarial deeds that modify the property’s geometry.
- When applying for urban planning or change-of-use licenses in most municipalities.
- When banks or investors require updated data before financing or acquisition.
In short, regularizing before selling or mortgaging is highly advisable — it saves time, money and legal risks.
3. Step-by-step procedure to regularize your property
Step 1. Collect current information
Request a nota simple (title extract) from the Land Registry and the Cadastral description and map from the Spanish Cadastre’s official website.
Compare boundaries, areas and ownership details.
Step 2. Create the GML file (Georeferencing)
The GML (Geographic Markup Language) file defines the property’s geometry using official coordinates.
It must be prepared by a qualified architect, surveyor or engineer, following the 2015 Joint Resolution of the Land Registry and Cadastre.
Step 3. Validate the file
The technician must validate the GML using the Cadastre’s official validation tool.
A positive validation report (IVG) will confirm that the geometry meets cadastral standards.
Step 4. Notarial and registral incorporation
The notary includes the georeferenced representation in the property deed.
The registrar then verifies the correspondence with the Cadastre and records the graphic coordination in the Registry.
Step 5. Final coordination and confirmation
Once registered, the Land Registry communicates the updated geometry to the Cadastre.
If both datasets match, the property obtains the “coordinated graphically” seal, which appears on all future Registry notes.
4. What problems does coordination prevent?
Proper coordination is not only a technical formality — it ensures legal certainty and financial security.
It helps prevent:
- ❌ Duplicate or overlapping plots with neighboring properties.
- ❌ Surface errors affecting deeds, energy certificates or tax values.
- ❌ Delays in sales, inheritance or mortgage processes.
- ❌ Problems obtaining licenses or declaring new construction.
- ❌ Tax inconsistencies (IBI, plusvalía, or reference value mismatches).
In 2025, with the growing use of GIS tools and cadastral verification by notaries, registrars and banks, an uncoordinated property is a risky property.
