In representing a client, a lawyer shall exercise independent professional judgment and render candid advice. In rendering advice, a lawyer may refer not only to law but to other considerations such as moral, economic, social and political factors, that may be relevant to the client’s situation. In a matter involving or expected to involve litigation, a lawyer should advise the client of alternative forms of dispute resolution that might reasonably be pursued to attempt to resolve the legal dispute or to reach the legal objective sought.
