The legal topics covered in this book are organized along a continuum, beginning with a summary of the laws and regulations that cover licensure and certification, third-party reimbursement, and professional incorporation. This is followed by a review of the different issues at the legal-behavioral science interface: the areas in which mental health professionals are asked to provide such services as evaluations of the mental status of litigants, the preparation and presentation of expert testimony in court, and the delivery of psychotherapy services to court-referred juveniles and adults. The more indirect ways in which the mental health professional can be involved and in which mental status issues are, on occasion, prominent (e.g., divorce proceedings or termination of parental rights) are also identified and summarized.
