Verified reviews of this service

It is the notarial act through which a newly built building, extension, or major renovation is officially registered at the Property Registry. This procedure legally certifies the existence of the construction on your land.

Without this declaration, your construction has no legal recognition and you cannot sell, mortgage, or transfer it by inheritance.

It is mandatory in these cases:

• When you build a new structure on land
• When making extensions that increase the built area
• In complete renovations that substantially modify the construction
• Before selling, mortgaging, or transferring the property
• To divide a building into several independent properties (horizontal division)

Yes, the process is 100% digital. You only need a computer with camera and microphone, and your digital certificate. The electronic signature before a notary via video conference has the same legal validity as an in-person signature.

Notario.org coordinates the entire process: document review, notary appointment, electronic signature, and registry registration.

Required documentation:

• Property title: Deed proving you own the land where the construction is located
• Planning permit: Municipal authorization certifying legality
• Technical certificate: Signed by architect describing the work
• Energy certification: Mandatory for new buildings
• Utility certificates: Water, electricity, and gas properly installed
• Digital certificate: For electronic signature

The online process is completed in 24-48 hours from when you send us the complete documentation until you receive the signed deed. Registration at the Property Registry may take an additional 15-30 days, depending on the registry's workload.

This represents time savings of 60-70% compared to traditional in-person procedures.

New Construction in Progress: Declared when the project is not yet finished. Allows registering the construction before completion, useful for real estate developments that need to sell off-plan.

Completed New Construction: Declared when the building is completely finished and ready for occupancy. This is the most common case for private homes.

If you built without a permit or it has expired, you must first regularize the situation with the corresponding city council. Depending on the municipality and circumstances, you may:

• Apply for a retrospective building permit
• Obtain an antiquity certificate (for constructions over 4-6 years old depending on region)
• Use urban legalization procedures

We advise you on the best route for your specific case before starting the notarial procedure.

Yes, the public deed granted through electronic signature before a notary has exactly the same legal validity as one signed in person at a physical notary office. It is regulated by Law 24/2001 and is fully recognized by all registries and public bodies in Spain.

The digital certificate guarantees your identity securely and the video conference with the notary ensures you understand the content of the document you are signing.

If the Property Registry detects any correctable deficiency, the notary receives a qualification note indicating what needs to be corrected. We take care of solving these defects and resubmitting the deed at no additional cost to you.

In exceptional cases of non-correctable defects, we advise you on the available legal alternatives.

Yes, it is possible to declare multiple constructions in a single deed if they are on the same property or are part of a unitary project. This is common in real estate developments with multiple homes.

You can also make independent declarations if the constructions are on different properties or you prefer to separate them for management or sale reasons.

You don't need to travel at any point in the process. Everything is done online:

• Documentation sent by email or secure platform
• Review and consultations by phone or video call
• Deed signing via video conference with the notary
• Document receipt in digital format

You only need an internet connection and a device with camera and microphone.

It is a document that rates your building's energy consumption on a scale from A (most efficient) to G (least efficient). Since 2013 it is mandatory for all new constructions before their first occupancy or sale.

It is prepared by a qualified technician (architect, engineer, or certified technician) after evaluating the insulation, installations, and climate control systems of your construction. Its cost usually ranges from €150-400 depending on the property size.
