Rectification of new construction: the registrar cannot demand a new license if the technician corrects their certification

Key data

If you have new construction registered in the Property Register and need to correct a technical error in the original certification, this resolution protects you. The Property Register of Albacete no. 4 suspended the registration of a new construction rectification deed claiming that the new technical certification—by differing from the initially registered one—required a new building and occupancy license. The DGSJFP, in its Resolution of July 22, 2026, upheld the appeal filed by the notary and overturned that negative rating.

The key lies in who has the authority to assess whether the constructed work corresponds to the licensed project: the competent technician, not the registrar or notary.

What does this regulation establish?

The resolution clearly establishes the scope of the technical certificate's function in the new construction registration process:

• The technical certificate's function is to certify the correspondence between what was built and the licensed project. This is a matter of fact, not law.
• The assessment of that correspondence is exclusively the responsibility of the competent technician. Neither the notary nor the registrar has technical authority to question it.
• When the same technician who issued the original certification corrects errors in that certification, such correction does not equate to a work extension or substantial modification requiring new administrative authorization.
• The registrar's negative rating note was also criticized for formal insufficiency: it merely cited legal provisions without justifying their concrete application to the case.

The resolution reinforces established doctrine: rectifying errors in a technical certification is not the same as extending work. Confusing both scenarios creates unjustified registration obstacles and unnecessary costs for the owner.

Economic and operational impact

The registrar's negative rating, if not appealed, forces the owner to initiate an administrative process to obtain a new building or occupancy license. This entails:

• Direct costs: architect or surveyor fees for new technical documentation, municipal license fees, additional notary fees for new deeds.
• Time costs: municipal license processing timelines can exceed 3-6 months in many municipalities, blocking sales, mortgage, or inheritance operations that depend on registration.
• Risk of operation paralysis: a suspended rectification deed blocks any transfer or charge on the property until the registration situation is resolved.

This resolution allows avoiding the entire process when the cause of the discrepancy is an error by the technician in their previous certification, not a real difference between what was built and what was licensed. The savings in costs and time can be significant in real estate operations with tight timelines.

Who does it affect?

• Owners and developers who have registered new construction and need to rectify the registration description due to errors in the original technical certification.
• Notaries who authorize new construction rectification deeds and receive negative ratings from the registrar for this reason.
• Property registrars, who must adjust their rating criteria to this DGSJFP doctrine.
• Architects and surveyors who issue technical end-of-work certificates and must correct errors in previous certifications.
• Lawyers and real estate advisors who manage operations on properties with descriptive discrepancies in the Register.

Practical example

A developer registered a single-family home in the Property Register with a built area of 180 m² according to the technical end-of-work certification. Years later, when preparing the property sale, the architect who signed that certification discovers they made a measurement error: the actual built area is 195 m², exactly matching the project licensed by the Municipality.

The architect issues a new certification correcting that error. The notary authorizes the new construction rectification deed. The registrar suspends registration claiming that the new certification differs from the registered one and that a new building and occupancy license is needed.

Applying the doctrine of the DGSJFP Resolution of July 22, 2026: the registrar cannot demand that new license. Assessing whether the 195 m² correspond to the licensed project is the exclusive responsibility of the technician, not the registrar. The rectification must be registered without requiring new administrative authorization, avoiding months of processing and additional costs that would have blocked the sales operation.

What should companies do now?

1. Review your properties with descriptive discrepancies: if you own properties registered whose registration description does not match the actual construction, analyze whether the cause is an error in the original technical certification.
2. Request a corrective certification from the competent technician: if the error is from the technician who certified the work, ask them to issue a new certification correcting that error, proving that what was built does correspond to the licensed project.
3. Instruct your notary about this resolution: when authorizing the rectification deed, the notary must know the DGSJFP doctrine to counter any eventual negative rating from the registrar.
4. If the registrar suspends registration, appeal: the appeal route to the DGSJFP is the mechanism that has proven successful in this case. Do not assume that the negative rating is final.
5. Demand that the rating note be reasoned: the DGSJFP expressly criticized that the registrar's note merely cited provisions without justifying their concrete application. An insufficiently reasoned note is easier to appeal.
