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 Arizona, the professional conduct of attorneys is regulated by the Arizona Rules of Professional Conduct, which are enforced by the State Bar of Arizona. These rules outline the ethical obligations and standards for attorneys practicing in the state. Attorneys can face disciplinary action for various infractions, such as neglecting their duties, misusing client funds, or failing to pay bar dues. The Arizona Supreme Court has the ultimate authority over the practice of law in Arizona and can impose sanctions ranging from reprimands to disbarment. The State Bar of Arizona operates a disciplinary system to investigate and adjudicate complaints against attorneys. Individuals can check an attorney's disciplinary history and current standing by visiting the State Bar of Arizona's website or contacting the organization directly. It is important to ensure that any attorney you consider hiring is in good standing and is eligible to practice law in Arizona, as hiring an attorney with a suspended or revoked license can have serious repercussions.
