The main objective of this work was to analyze how parenthood is performed by heterosexual parents during the period of conjugality and after they cease to be a conjugal couple, mainly regarding the guarantee of family coexistence for their children, observing whether social factors have interfered in these relationships. It was also sought the analyses of the frequency and quality of the offspring s interaction with both lineages – maternal and paternal – after marital split and of the challenges encountered in the composition of resources to support the offspring, during the marital relationship and also after separation. Through a qualitative approach, the research process adopted document analysis and semi-structured interviews to produce empirical data, and content analysis for its discussion. The documental corpus was composed by Social Work s first contact forms, cases in the area of Family Law and extrajudicial agreements made in the Interdisciplinary Group for Conflict Mediation, all available in the internal system of the Nucleus of Legal Practice (NPJ) of PUC-Rio. After reading this material, semi-structured interviews were conducted with NPJ users who showed interest and availability. Even in the information collected from male respondents, it was evident the woman s role as the main caregiver of the children and the home, referring the permanence of such attribution to the mother or another female figure. Another important data was the existence of conflicts regarding the exercise of parenthood already during the period of conjugality that, in some way, were supported or managed. After marital split such hindrances are externalized and support is requested to deal with such situations. In all cases, was also perceptible the regret of the interviewees for having to resort to a third way to resolve existing conflicts in the family nucleus.
