EC 7-3.

Where the bounds of law are uncertain, the action of a lawyer may depend on whether he is serving as advocate or adviser. A lawyer may serve simultaneously as both advocate and adviser, but the two roles are essentially different. In asserting a position on behalf of his client, an advocate for the most part deals with past conduct and must take the facts as he finds them. By contrast, a lawyer serving as adviser primarily assists his client in determining the course of future conduct and relationships. While serving as advocate, a lawyer should resolve in favor of his client doubts as to the bounds of the law. In serving a client as adviser, a lawyer in appropriate circumstances should give his professional opinion as to what the ultimate decisions of the courts would likely be as to the applicable law.
