The short version
- Licensure is required; insurance is not, by law. Washington's Department of Health licenses mental health counselors, marriage and family therapists, and independent clinical social workers (RCW 18.225); Idaho licenses counselors, therapists, and social workers. We found no malpractice insurance requirement in either state's licensing law.
- In practice, you will need it. Insurance panels, group practices, agencies, and office leases commonly require professional liability.
- Washington's duty to warn is written into law. RCW 71.05.120 preserves the duty to warn or take reasonable precautions when a client communicates an actual threat of physical violence against a reasonably identifiable victim, and says the duty is discharged by reasonable efforts to warn the victim and law enforcement.
- Records carry heightened protection. Washington's health care information law restricts disclosure of mental health records (RCW 70.02.230), and a breach of client data triggers state breach notice rules.
- Board complaints happen more than lawsuits. License defense coverage pays for responding to a complaint to the licensing board, a frequent source of cost even when the complaint is dismissed.
