The aim of this Master thesis is to discuss the impact of unconscious psychic transmission of traumatic elements in the constitution of marital identity. The route of this theoretical work begins with the investigation of the unconscious dimension of conjugality and love choice, emphasizing the specific characteristics of the marital bond. The study of the concept of unconscious psychic transmission and identificatory mechanisms that enable the transmission between members of the couple was required to understand the conjugal identificatory processes considered relevant for the formation of the marital self. The psychic transmission of traumatic elements in conjugality, emphasizing the structural aspect of the transmission of trauma, is adressed. It is assumed that the ghosts that haunt the couple bedroom are related to traumatic aspects that each partner brings from their experiences with the first objects of love -whether primary or oedipal objects –, which are republished in conjugality. It is considered that this traumatic experience is constitutive of the normal conjugality; in other words, related to neurosis. It is concluded that the conjugality mobilizes intense instinctual load, which is not only a result of the transmission between partners, but also the result of the legacy which the couple carries from their ancestors. The couple s relationship, therefore, includes the reissue of object relations of the past, while the tryst allows the exercise of creativity and the re-creation of the ego. The coexistence, which is often difficult, of these two poles was addressed in this research so as to deepen the understanding of the paradox repeat/create inherent in the marital bond.
