It is not per se unethical for an attorney who examines titles for a savings and loan association to handle the corrective work required by his title opinion and charge the seller for such corrective work provided the seller has requested him to provide such services either directly or through the association, since this is a matter of contract law rather than ethics. The particular factual situation may bring other ethical considerations into play, however, such as conflicts of interest or representing someone already represented by counsel as possibly might be the case in obtaining a release of a child support lien.
