Owners of holiday rentals: private authorisation is insufficient to request a rental registration number

The Directorate General for Legal Certainty and Public Faith has suspended the assignment of a short-term rental (tourist use) registration number because the authorisation submitted was a private document lacking notarial authentication (legal grounds). The Land Registrar of Seville No. 2 refused the entry, ruling that such authorisation is not a valid title to prove the representation of co-owners (Art. 3 of the Mortgage Law and Arts. 33 and 34 of the Mortgage Regulations).

In 2 key points

  1. Private authorisations are not valid titles for performing registry entries or proving representation (Art. 3 Mortgage Law) (fundamentos de derecho)
  2. Compliance with the principle of authentic title is required to access the Registry Books (Arts. 33 and 34 Mortgage Regulations) (fundamentos de derecho)

How it affects those involved

For owners of properties intended for holiday rentals, particularly those held under joint ownership, private authorisations between co-owners are not valid for registration procedures regarding the assignment of a registration number (legal grounds). The use of authentic titles or documents with notarised signatures is required to prove representation and avoid the suspension of the application.
