A Sole Practitioner Has a Sign on Her Door Stating

A sole practitioner has a sign on her door stating that she practices general business law, personal injury, and family law. The attorney employs two paralegals and a secretary. The attorney personally handles all general business law cases, but assigns all of the personal injury cases and family law cases to one of the paralegals. The attorney fully and appropriately supervises all work performed by the paralegals and pays them a salary, plus fifty percent of all fees received from the cases assigned to them. Is this arrangement permissible?

A) Yes, because employees of a law firm may share the fees generated by the firm.
B) Yes, because the attorney fully and appropriately supervises all work performed by the paralegals.
C) No, because attorneys are prohibited from splitting fees with non-attorneys.
D) No, because the attorney is facilitating the unauthorized practice of law by the paralegals.
