Legal Question in Family Law in Georgia

There is no way to answer your vague question as posted. I assume you have an actual fact pattern and to get an answer you'd need to post those facts.

Since depositions are almost never quashed and divorce is NEVER a pro se proposition, instead of asking here, you should retain a lawyer.

Your question is not appropriate. No one here is going to spend the time going over all the possible reasons. If you have a specific question, state all the facts and ask the question.
