I'm not licensed in Connecticut so don't take the above as legal advice, it's just a link that may help you find what you are looking for. Good luck.
In Connecticut, you should contact the Statewide Grievance Committee at email@example.com or (860) 568-5157; Fax: (860) 568-4953. If you look on the state website, it will only tell you the CURRENT status of the attorney, not past misconduct. You always want to ask if the attorney has EVER been suspended, disbarred or otherwise reprimanded or disciplined for misconduct. For people in other states, every state is different, but you can always start with your state bar.
