The practice of professional counseling is governed at the national and state levels by a variety of governing boards and regulatory agencies. This chapter focuses on the legal and ethical issues that are salient to clinical mental health counselors. Specifically, it discusses the American Counseling Association (ACA) Code of Ethics, the American Mental Health Counselors Association (AMHCA) Code of Ethics, state licensure and national certification, confidentiality, mandated reporting, duty to warn, and scope of practice. The chapter also focuses on the responsibility of counselors to engage in ethically based practice. In addition, the chapter connects the ACA and AMCHA ethical codes and the Council for Accreditation of Counseling and Related Educational Programs standards to several topics in ethical practice, including values clarification, bias assessment, boundary awareness and maintenance, and self-reflection. The chapter concludes with a case scenario to illustrate chapter concepts and a section on resources to provide further information.
