EC 3-7.

The prohibition against a non-lawyer practicing law does not prevent a layman from representing himself, for then he is ordinarily exposing only himself to possible injury. The purpose of the legal profession is to make educated legal representation available to the public; but anyone who does not wish to avail himself of such representation is not required to do so. Even so, the legal profession should help members of the public to recognize legal problems and to understand why it may be unwise for them to act for themselves in matters having legal consequences.
