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 Louisiana, the professional conduct of attorneys is regulated by the Louisiana Rules of Professional Conduct, which are established by the Louisiana Supreme Court. The enforcement of these rules is carried out by the Louisiana Attorney Disciplinary Board, which operates under the auspices of the Louisiana Supreme Court. Attorneys in Louisiana can face disciplinary action for various infractions, including but not limited to non-payment of bar dues, misappropriation of client funds, or other ethical violations. The Louisiana State Bar Association provides resources for checking an attorney's disciplinary history, and such information can typically be found on their website or by contacting the bar association directly. It is important for clients to ensure that they do not hire an attorney who has had their license suspended or revoked and is thus ineligible to practice law in the state. The disciplinary process is designed to protect the public and maintain the integrity of the legal profession.
