The ABA's Committee on Ethics and Professional Responsibility issues formal and informal ethics opinions. Formal opinions are issued on matters that are deemed of general interest to the bar; informal opinions are issued for specific inquiries relating to a particular set of facts.
The full text of ethics opinions from state and local bar associations are not collected in any one place. The sources described below will assist you in locating state bar ethics opinions on a particular topic. Most state bar associations publish opinions in the state bar journal or newsletters, but some do not publish their ethics opinions at all. Some state bar associations publish a looseleaf reporter with their ethics opinions or make their opinions available online.
