Play therapists work with minor children in their practice; therefore the play therapist must be cognizant of the special circumstances under the law and major professional codes of ethics that apply to this special population. Major court cases, legislation, and critical issues are condensed in this article.Play therapy is a multidisciplinary therapeutic intervention for children. While this brings about a montage of theories and strategies, this diversity brings more than one code of ethics, licensing board, and form of verifying competency into the professional identity. Many play therapists are members or follow one of the major codes of ethics for the mental health community: American Counseling Association (ACA), American Association of Marriage and Family Therapists (AAMFT), American Psychological Association (APA), or National Association of Social Work (NASW).Social workers, professional counselors, and psychologists are part of professional mental health workers who are governed by state boards in most states. The professional codes of conduct and standards of practice are usually reviewed and acted into law. Therefore, when a code of ethics is violated by a mental health worker, a law is most often broken. The mental health worker's license is not only in danger of being revoked, but the licensee may be facing criminal charges under the state's legal code. A licensing board may hold a great deal of power granted to them by the state legislature to influence the limitations of practice or to require practice under supervision for an extended time.
