Several years ago the NAR Professional Standards Committee abolished the policy that allowed local boards as a matter of local option to automatically join a REALTOR® (principal) in any complaint against a REALTOR® (non-principal). Consequently, the salesperson would be the only respondent in the ethics complaint unless the complainant names principal broker B as a co-respondent in the complaint, or if the Grievance Committee believes there is potential culpability on broker B’s part.
