The data of personal character that figure in the Estate Property Register, are data protected by the regulations of protection of particulars. According to the Law of the Property Register, the Town Council or, if it is proper, other public administrations, can use the data of the owners for the exercise of its own competences, with the limitations derived from the principles of competence, suitability and proportionality (article 52.2.a) of the Law of the Property Register). The communication of the data of the property register in collaborator companies would not be protected by the general regime of cessions (article 11 LOPD) unless the consent of the headlines is counted. The personal access and the posterior personal data processing that the company has to make, if it acts on account of the Town Council, it should articulate through an order of the treatment (article 12 of the LOPD and 20 to 22 of the RLOPD).
