Can any professional us the title Esquire?

The title "Esquire" (abbreviated as "Esq.") is traditionally used in the United States to denote a licensed attorney or lawyer. While it is not a formal title and does not require any specific qualifications, it is generally reserved for individuals who have passed the bar exam and are practicing law. Other professionals can technically use the title, but it is typically seen as misleading unless they are indeed attorneys. Therefore, it is best practice for only licensed lawyers to use the title "Esquire."
