The inclusion in the registration certificates or flyers of the name and surnames of all the persons registered in the same address, at the request of one of the registered persons, may be protected by the consent of all the persons affected or, in the absence of consent, in the legitimate interest of the applicant, unless there are circumstances in the specific case that, after making the appropriate weighting, should lead to the prevalence of the right to the protection of personal data of the other people affected. To this end, it is of particular importance to inform the affected persons of the communication in advance of the effects that may be exercised, where appropriate, by the right of opposition.
