This study explores the crying episodes of twenty‐eight clients treated at a family therapy service in a community centre. The crying episodes were associated with some significant elements: the time of appearance, the content and triggering factor, the interpersonal context of sessions and the emotions clients had for the therapist, as well as the therapy's outcome (end of treatment and the satisfaction of clients). Crying was much more frequent during the first session. It occurred more frequently when there was another family member present. The proportion of clients who cried during the treatment was significantly higher for clients who completed it successfully. Clients who cried perceived the therapist, in all cases, as a kind person who never got annoyed with them. Crying could be considered a type of behaviour that helps the therapist to create a safe context and foster the therapeutic alliance.
