A citizen requests the obtaining of copies of the Estate Property Register of Rústega of the town. The data of the cadastral headlines that are physical persons, and that are evident to the Property Register, are data protected by the LOPD. To hand over particulars the consent of the headline is necessary, unless, among others, a law authorizes the cession. The Law of the Property Register establishes an access restricted to the treated data, and requires the consent of the headlines or the concurrence of suppositions rated in the law itself. The participation of the citizen as a witness in a notarial writing does not mean a sufficient legal habilitation, is then not a foreseen supposition to the Law of the Property Register. Therefore, the cession in this case is not protected by the LOPD, without harm of the possibility to resort to the consultation of other public Registers.
