Itsy, Laughing gave you some very good advice. Turn the financial documentation over to your lawyer/accountant and let them do the math on this for you. Send him an email and ask him for a copy of what he has in the way of documentation and leave it at that. There is no need to have a long winded discussion over it since your accountant has already filed your taxes and told you what you could or couldn't claim. Give him enough rope and he'll hang himself yet.
As for him being in mlc, no one can say for sure. However, what he's stated in that note to you is all about money and taxes. It's about deductions that he wants to claim and many people do these things to their exes and they are quite sane. Your xh is trying to get all that he can from the final year of the marriage and unfortunately, he's going to find out the hard way that many of the deductions will not fly. But, that's something he has to find out on his own. Your main concern is with you at this time.
If your xh is still floating around in mlc, the euphoria of the divorce hasn't worn off. This could take at least 6 months, depending upon what's been going on w/him. Itsy, I'm going to give you some advice and you may not want to hear it, but here goes. You are divorced, your xh has behaved poorly towards you for a long time, it's time to place the focus on to yourself and your family. Leave that man out there to swing in the wind. He doesn't deserve your attention right now. You've gone through so much and it's time to find out what Itsy wants to do w/her life and go for the gold. If your xh ever wakes up and realizes what he's done and comes to talk to you about it, that will be the time to turn your focus back on to him, i.e., it will be your decision to reconcile or not. However, for today, look to your future and know that no matter what happens, you are going to be okay.
