In this paper, we seek to understand how gender norms and heteronormativity impact the custody and regulation of the bodies of young people in "conflict with the law". The work was developed based on the main results found in qualitative research carried out within a multi-institutional body composed, among others, by bodies of the justice system and the public security in the state of Minas Gerais. Based on the methodology of participant observation and interviews, it was possible to identify the dynamics of production and reproduction of gender inequalities in the flow of care for adolescents at a domestic Juvenile Justice assistance center. Under the queer theory, we found out that such dynamics were also capable of governing the relationship between the professionals working in that context, according to the logic of hierarchy, stereotype and containment of behaviors diverging with heteronormativity.
