I am confused about the conflict of interest rules. When can I represent another client when it involves the interest of a former client?

The conflict of interest rules are set forth in Rule 1.7, the General Conflict of Interest Rule of Existing Clients; Rule 1.8, which is the Specialized Conflict of Interest Rule; and then Rule 1.9, which is the rule that concerns the Conflict of Interest involving Former Clients. Rule 1.9 is titled appropriately, “Duties to Former Clients.”
