The present research, presented in the format of two articles, has the general objective of investigating the dimension of the right to access the origins, guaranteed by Law to adoptees. The interest in the theme emerged from a paradigmatic situation held in one of the Juvenile Courts of the State of Rio de Janeiro, in which the biological mother sought the Judiciary in order to establish contact with her daughter who had been voluntarily relinquished more than 30 years ago. To achieve the general objective of this work, we reflected on the importance of including in the field study the representatives of each of the vertices of the adoptive triad – biological family, adoptee and adoptive family - in view of the particularities of its dynamics for the analysis of the proposed theme. Thus, we conducted separate semi-structured interviews with the mother, the contact applicant, the daughter and the adoptive mother. The interviews were analyzed according to the content analysis method and the categories that emerged from the collected material were linked to the literature on voluntary relinquish, search and reunion and mediation by the Judiciary. We realized that the experience of the contact mediated by justice had a positive evaluation of those involved, working in an integrative way for the components of the triad. However, the lack of a specific protocol related to this kind of situation almost made the technical intervention in the case unfeasible, which points to the need for some systematization by the Judiciary on this type of demand.
