The purpose of this paper is to bring the necessary reflection on the legal discipline appropriate to the causa mortis transmission of social network profiles, considering that the Brazilian legal system still does not have a specific regulation on the subject and the current discipline of Book V of the Civil Code is insufficient, if not inadequate, to regulate and protect these new succession situations. From the methodological perspective of civil-constitutional law and based on a critical analysis of the legal literature, foreign legislations and jurisprudences, and bills involving the theme of digital inheritance, the dissertation proposes that social network profiles should follow the destiny that was expressly indicated to them by the user during his lifetime in the exercise of their right to informative self-determination and existential private autonomy, either through the tools made available by the platforms, or through the classic mechanisms of succession planning, warning that such manifestation of last will finds limits in the protection conferred to the fundamental rights of third parties with whom the deceased has dialogued on his social networks and other relevant interests that are legally protected.
