Using a clinical example of my work with a patient who signed a nondisclosure agreement (NDA) following a sexual assault, I examine the impact of legal silencing in the aftermath of trauma. I describe how NDAs function as coercive instruments of powerful institutions and patriarchy. By closing off access to social and political space, the victim’s responses are compressed into the intrapsychic domain where they are experienced as shame, self-doubt, and worthlessness. Outrage is turned inward and shame is transferred to the victim. Silencing and isolation collapse mental space for thinking and prevent the relational processes necessary for recovery. I argue that NDAs are an ethical betrayal of victims by the institutions that use them, and by society in allowing them. The therapist’s role as witness and ethical ally is discussed. I reflect on motives for, and dilemmas inherent in, writing about a treatment in which the patient is legally silenced.
