Monitoring a family suffering from many traumatic experiences has led us to look at the modalities of sharing the unthinkable in family therapy when it is punctuated by intrusions of the reality of the therapists and of current events. In the first place, sharing requires a secure setting to accommodate the raw traces of the trauma with its disorganizing effects which prevent the family from living together and from separating from one another. Secondly, the sharing of representations fosters access to an intelligible common history. Finally, faced with the risk of the intrusion of and collusion with the private lives of the therapists and current events, thinking about the modalities of sharing between therapists and patients is necessary. It is a question of preserving the continuity of the setting, of containing what is private and of elaborating the transference/countertransference and intertransference movements. Thus the treatment of trauma through sharing in the neo-group allows for the appropriation in the symbolic register of a history of which each one can become the active heir.
