For example, consider several cases:
- Layperson with no formal legal education
- Current law school student
- Law school dropout
- Graduated law school, but did not pass the bar
- Passed the bar, but did not attend law school
- Graduated law school, was admitted to the bar, but does not have an active license
- Graduated law school, was admitted to the bar, and is an attorney in private practice
- Graduated law school, was admitted to the bar, and is e.g. an attorney for the government
- Graduated law school, was admitted to the bar, and is e.g. an engineer doing technical work rather than practicing law
- Graduated law school, was admitted to the bar in a state other than the state where s/he is speaking (but not in the state where s/he is speaking)
- Graduated law school, was admitted to the bar in a state other than the state where s/he is being heard (but not in the state where s/he is being heard)
I assume that only 4 and 6-11 are allowed to use "JD" after their names (but am not sure; answers can clarify that.) Of the folks described above, who is customarily allowed to use "Esq." after their names? Under what conditions, if any, would a person choose one or the other (or neither or both)?
If needed, feel free to distinguish between any formal requirements and what others experienced in practice would expect or find offensive.
