text_A: The title of doctor has always been used to address lawyers in England and other common law countries (with the exception of the United States). This is because until 1846 lawyers in England were not required to have a university degree and were trained by other attorneys by apprenticeship or in the Inns of Court. Since law degrees started to become a requirement for lawyers in England, the degree awarded has been the undergraduate LL.B. In South Africa holders of a LL.B, who have completed a year of pupillage and have been admitted to the bar may use the title "Advocate", abbreviated to "Adv" in written correspondence. Holders of an LL.B who have completed two years of clerkship with a principal Attorney and passed all four board exams may be admitted as an "Attorney" and refer to themselves as such. Likewise, Italian law graduates who have qualified for the bar use the title "Avvocato", abbreviated in "Avv."
text_B: If a lawyer referred to themselves as "doctor," could you make an educated guess as to whether they're from England or the United States?
YES.
