Contemporary psychoanalytic studies show a growing interest in research aimed at generational psychic transmission, especially regarding its transgenerational aspect. The interest in transgenerational psychic transmission shows how important investigating that topic has become in the current scenario, following a path that provides greater support to clinical practice and to the dialogue between psychoanalysis and other areas of knowledge. One of the areas with which the topic of this study establishes a close dialogue is Law, and we identified the contributions that psychoanalytic theory and practice may offer the legal area. The main goal of this thesis is to investigate how the transgenerational psychic transmission fits in the context of legal disputes, especially in divorce litigation. To achieve that goal, four studies were conducted that resulted in four articles. The first one focuses on postdivorce family dynamics, considering that any separation results in painful processing of the grief for a broken marriage, as well as in an inevitable change in family interactions. The second study analyzed the effects of transgenerationality on children and the symptomatic production of children. The third one aimed to understand fatherhood in families that experienced litigious divorce. The fourth one focused on conflict and the transposition of marital disagreements into the legal sphere. This study aimed to analyze how the extension of conflicts creates deadlocks for psychic transmission, resulting into endless legal battles. Based on our analysis, we question whether the legal system is ready to perform its primary function, using its genealogical power (Legendre, 1999) to support the process of formation and subjective transformation. We conclude that the legal area needs to create and maintain integrated actions with the mental health area, mainly with psychoanalysis, to solve family conflicts that mobilize the judiciary and turn into endless cases that burden it. To reduce the judicialization of family relationships, it is essential to consider the unconscious psychic dynamics and the psychopathology of individuals involved in litigation. Psychology and psychoanalysis should go beyond reports and statements and aim to reestablish the psychological health of those involved in legal cases.
