HI D.---So sorry to hear of your situation. While I have no experience with divorce and with only a couple of friends who have, I can't help much there...except to say that our guy friends complained excessively about how much $ their wives got in a settlement.
My advice is this. Hire an attorney who will get you your fair share. You shouldn't have been denied access to funds. A good lawyer will revisit that and I'm sure hiring him/her will more than pay for itself if this decision can be revisited. If he had a lawyer, I'm sure they pulled more than one trick out of the bag to play on you.
I don't know what you would be entitled to...but you need an expert to advise you on exactly that. Good luck and let us know how it turns out. D.
