In custody and parenting time cases, it seems to be standard practice to require production of the parties' mental health records to expert witnesses. In fact, the last three retainer agreements provided to me by potential expert witnesses on the issue of custody and parenting time included some variation of the following language: "Releases need to be signed by [the client] to permit this psychologist access to all educational, medical, psychological, legal, hospital, social services, and other records relevant to this assessment."
