Tourist rental companies: Unique Registration Number (NRU) cannot be assigned if the property is not registered in the Land Registry

The Directorate General for Legal Certainty and Public Faith has confirmed the suspension of Unique Registration Number (NRU) assignments for short-term rentals where the building lacks official registration. To obtain this number, the property must first be registered in the Land Registry, adhering to the principles of successive chain of title and speciality (Articles 9 and 20 of the Mortgage Law). In this instance, as only the plot of land is registered and urban planning legality cannot be proven in an easement zone, the application is inadmissible.

In 2 key points

  1. Requirement for prior property registration to assign the NRU, in accordance with the principle of successive chain of title (Art. 20 Mortgage Law) (art. 20 Ley Hipotecaria)
  2. Obligation to precisely identify the estate, nature, and characteristics to comply with the principle of speciality (Art. 9 Mortgage Law) (art. 9 Ley Hipotecaria)

How it affects those involved

For companies owning properties intended for tourist rentals, the failure to register new construction in the Land Registry prevents obtaining the NRU required for legal operation (Facts I). This creates an operational deadlock if the building is located in protected easement zones without the mandatory administrative authorisation, as its urban planning legitimacy for tourist purposes cannot be presumed.
