Sharenting e responsabilidade civil parental: limites à exposição de crianças e adolescentes nas redes sociais

The exposure of children and adolescents on social media by their parents or guardians, known as sharenting, raises legal issues concerning comprehensive protection, personality rights and the limits of parental authority. Although sharing family records may be a legitimate form of expression, repeated, humiliating, excessive or commercially exploited disclosure may affect the image, privacy, dignity and safety of developing persons. This study analyzes the circumstances in which digital exposure by parents or guardians exceeds the limits of parental authority and may give rise to civil liability. It adopts a qualitative, bibliographical and documentary approach based on legislation, legal scholarship, scientific articles and institutional documents. It examines constitutional and statutory protections, the Brazilian General Data Protection Law, the Digital Statute of Children and Adolescents, and the requirements for civil liability. It argues that liability does not automatically arise from every publication; the specific circumstances, possible unlawfulness or abuse of rights, damage and causal link must be assessed. It concludes that parental authority must be exercised consistently with the best interests, evolving autonomy and personality rights of children.
