The purpose of this study is to investigate the experience of divorced parents who fight for the shared custody of their children. The authors interviewed 12 subjects – 10 men and 2 women – the authors recruited participants online, from Facebook pages that serve as a support network for parents who fight in the legal system for the shared custody of their children. As an investigative tool, was used an online interview with open questions. The participants words, registered in the Messenger app, were submitted to the content analysis method in its thematic category model. From the narratives, seven categories of analysis emerged: Conflicts relating to marital litigation; Marital conflicts affecting the family routine, as well as the parent and children s relationship; Domestic violence associated with the breakup of the marital relationship; Priority the of maternal unilateral guard; Shared custody as an alternative to family living; Parental Alienation; and Criminalization of parental alienation. The category Domestic violence associated with the breakup of the marital relationship was divided into three subcategories: Justifications for marital violence: threat, revenge and cheating; Sexual violence associated with marital breakdown; and Presence of children in violence situations associated with marital breakdown. This study was presented in the format of four articles. From the results of the research, we conclude that when marital conflicts persist post-divorce and are manifested through a desire for revenge and violence, parental s care is impaired. In this contexto, different phenomena are generated that can mark the struggle for shared custody in post-divorce families, such as: domestic and intrafamily violence as a model of identification for the children; concepts of provision and care linked to the father and mother figures, respectively; expression of the litigation in the experience of parental alienation; and perpetuation of the litigation, hidden in the struggle for rights and explicit in the judicialization of family relations. The unfolding of conflicting marital separation can affect the relationship between parents and children, jeopardizing healthy child development, the right of the children to family interaction and the maintenance of parental bonds after the conjugal relationship breakup. In addition, it is relevant to note the importance of creating public services specialized in dealing with issues related to divorce and situations of violence associated with the end of the love relationship as a way of coping with the issues that cross the parental-filial relationship in the post- divorce context.
