EC 6-3.

While the licensing of a lawyer is evidence that he has met the standards then prevailing for admission to the bar, a lawyer generally should not accept employment in any area of law in which he is not qualified. However, he may accept such employment if in good faith he expects to become qualified through study and investigation, as long as such preparation would not result in unreasonable delay or expense to his client. Proper preparation and representation may require the association by the lawyer of professionals in other disciplines. A lawyer offered employment in a matter in which he is not and does not expect to become so qualified should either decline employment or, with the consent of his client, accept the employment and associate a lawyer who is competent in the matter.
