This work intends to study disappearance during childhood in Brazil. The few existing publications do not offer a deep reflection concerning the referred theme. There was great difficulty in elaborating this work due to the fact that the literature of renowned authors who study the phenomenon of child and adolescent disappearance in addition to domestic violence in Brazil could not be found. Therefore, for the conduction of this work and as justification for disappearance as the theme, web based researches through social medias and information from both the Legislative apparatus and the System of Assurance of Rights (Sistema de Garantia de Direitos – SGD) were used. For the study of domestic violence, the literature of contemporary thinkers was mentioned. Due to this context, the present study will be an important instrument of analysis and debate about domestic violence and the phenomenon of the disappearance of children and adolescents, thus, considering disappearance as an event that is mainly social, the burden imposed by society upon the missing ones or upon their families is removed and, in view of this, the matter is universalized, demonstrating that the problem must be faced by all.
