The professional conduct of attorneys is generally regulated by each state's rules of professional conduct—which are often written by the state's highest court, and enforced through the disciplinary process administered by the state's bar association. The professional conduct of attorneys is also referred to as legal ethics and professional responsibility.

Attorneys can be disciplined for a variety of reasons, ranging from the failure to pay their bar dues to misappropriating client funds. The grounds upon which an attorney may be disciplined by the state bar association are generally located in the state bar association's disciplinary rules of professional conduct.

Some attorneys who have been disciplined are no longer eligible to practice law. You should inquire about an attorney’s disciplinary history on the state bar association’s website, or by calling the state bar association.

You should not hire an attorney whose license is been suspended or revoked and who is not eligible to practice law in your state. Each state has a disciplinary organization that receives, investigates, and resolves ethics complaints against attorneys licensed in the state.

In Connecticut, the professional conduct of attorneys is regulated by the Connecticut Rules of Professional Conduct, which are adopted by the Connecticut Supreme Court. The enforcement of these rules is carried out by the Statewide Grievance Committee, which works in conjunction with local grievance panels and the Office of the Chief Disciplinary Counsel. Attorneys in Connecticut can face discipline for various infractions, including but not limited to non-payment of bar dues, misappropriation of client funds, conflicts of interest, and other breaches of ethical duties. The disciplinary process can result in sanctions ranging from reprimands to disbarment. Individuals can check an attorney's disciplinary history through the Connecticut Judicial Branch website or by contacting the Statewide Grievance Committee. It is important to ensure that any attorney you consider hiring is in good standing and eligible to practice law in Connecticut. Hiring an attorney who has been suspended or disbarred and is thus ineligible to practice is not advisable.
