attorney directory : An attorney at law (or attorney-at-law) in the United States is a practitioner in a court of law who is legally qualified to prosecute and defend actions in such court on the retainer of clients. Alternative terms include counselor (or counsellor-at-law), and lawyer.

The U.S. legal system has a united legal profession, which means that it does not draw a distinction between lawyers who plead in court and those who do not. Many other common law jurisdictions, as well as some civil law jurisdictions, do draw such a distinction: for example, the division of solicitor and barrister (advocate) found in the United Kingdom, and the division of advocate and civil law notary in Italy and France. An additional factor which differentiates the American legal system from other countries is that there is no delegation of routine work to notaries public or their civil law equivalent.
