I've never heard of this, so my first reaction is to question why a lawyer wants this? Your therapist, I would get it.
Your lawyer--I would think would only be interested in things that pertain directly to your divorce?
I just don't understand, so it's difficult to comment.
I can't understand why your distant past, pre-husband, would be relative to this. It seems this information could be used against you in court.
Are you paying for this lawyer, or is he?
