Confidence sharing is an asymmetrical dialogic episode to which both parties consent, in which one reveals something personal to the other who participates in the emergence and unfolding of the confidence. We describe how this is achieved at a discursive level within vocational counselling interviews. Based on a corpus of 64 interviews, we analyse the disclosure of confidences and the discursive procedures allowing their expression, the way the interactants manage the situation and the repercussions on the counselling interview.
