The research intends to examine the family relationships established from the bonds between fathers, mothers and children in the context of an irregular adoption. It is worth highlighting affectivity as a fundamental principle for this family structure in contemporary society. The study also encompasses the understanding around adoption in Brazil and its peculiarities, highlighting its evolution in Brazilian legislation. When dealing with Brazilian adoption, it is proposed to present a dialectical approach to its legal nature. The research investigates, through the analysis of jurisprudential decisions of Brazilian courts, the possibility of acknowledging Brazilian adoption based on the registration of voluntary socio-affective paternity and its repercussions, considering the best interests of the child.Acesso AbertoAdoçãoFiliaçãoPaternidade socioafetivaAfetoFamíliaAdoptionAffiliationSocio-affective paternityAffectionFamilyDissertaçãoSociais e HumanidadesMultidisciplinar
