I think I had 100 questions. I can't even imagine them asking for copies of your parents' wills. The divorce is happening while they are still alive and there are other children in the mix, which means you won't get but a portion of what's left to you, if anything. No one can predict what may happen down the road besides, if your parents have remarried, the spouses generally get first dibs on the money unless the will specifically states what is to be left to you. By that time, the parents could have blown the money or be heavily in debt that the parties left behind have to take care of. I do think that particular request is odd. I didn't have that one as one of my questions.
I do think that your h and his lawyer are going to draw this out until you have no money to pay your lawyer and that you are going to scream "Enough! I'll do whatever you want". The sad part about all of this is that the mlcer can't see what's in front of them. All of this could have been resolved, both of you divorced and moved on by now had he worked w/you. But, it goes against the grain for him that you asked for certain things and yes, you left the property in his hands and moved. He's not happy that you are no longer under his thumb and have to rely on him.
I wish that I could bottle all of them up and leave them on a remote island for a very long time. They are horrible to deal w/when it comes to filing and moving forward w/a divorce. They play on your emotional state and know which buttons to push. Keep your focus on the facts and leave the emotions out of the negotiations. He doesn't care how you feel about what he's done to you or the girls. Bottom line...money and what he can get away with in keeping from you.
