The Brazilian data protection authority ('ANPD') announced, on 17 March 2023, that it had published a technical note on the applicability of the Law No. 13.709 of 14 August 2018, General Personal Data Protection Law (as amended by Law No. 13.853 of 8 July 2019) ('LGPD') to deceased persons. In particular, the ANPD clarified that, in accordance with Article 6 of the Law No. 10.406 of 10 January 2002 for the Civil Code, the existence of a natural person ends with death; therefore, it is assumed that the LGPD only applies to the processing of personal data of living natural persons. To this end, the technical note further explains that data relating to a deceased person does not constitute personal data and is therefore not subject to the LGPD's protection.
