Do you have a D.L. or a S.J.D.? Just curious, I've never met a lawyer in the US who qualified as "Doctor." Most attorneys in the US (who went to law school in the US) don't have a doctorate, so it's a different situation than a Ph.D.
I used to work for an online school that insisted its law professors, who held JD,s be called Doctor. Ew. I've sometimes heard lawyers call themselves Doctor, when they had a JD, which is incorrect. Well, it's actually just incredibly self important and kind of embarrassing. I do not deserve to be called doctor; I see my J.D. as quite different than a Ph.D. or an M.D., D.O., etc.
And I call my older colleagues Mr. so and so, but I do call my opposing counsel by their first name.
I never knew there was a difference between law degrees. What makes one technically a doctor an the other not?
