A non-lawyer who undertakes to handle legal matters is not governed as to integrity or legal competence by the same rules that govern the conduct of a lawyer. A lawyer is not only subject to that regulation but also is committed to high standards of ethical conduct. The public interest is best served in legal matters by a regulated profession committed to such standards. The Disciplinary Rules protect the public in that they prohibit a lawyer from seeking employment by improper overtures, from acting in cases of divided loyalties, and from submitting to the control of others in the exercise of his judgment. Moreover, a person who entrusts legal matters to a lawyer is protected by the attorney-client privilege and by the duty of the lawyer to hold inviolate the confidences and secrets of his client.
