So, let him and his lawyer continue to make asses of themselves and get angry that he thinks you will be so easily beaten down.
Family judges have seen it all and they will certainly know of his scumbag lawyer and any judge worth his/her salt will size your soon to be ex up before he ever opens his mouth in a courtroom. So, you just make sure that lawyer of yours fights back just as hard. You want the house, alimony (if applicable), child support, the horses, half of any retirement monies, oh yeah, half of anything he bought overseas for his girlfriends and your portion of the law practice. Also, if he is the main bread winner, you want him to pay for college. You can make demands which are just as asinine as his, in the end he cheated on you so who do you think it going to garner the least sympathy of the court?
And remember, he is the one who cheated on you and squandered money on girlfriends. He has a sleazebag lawyer who is going to be paid to grind you down and screw with your head. So, yes, let your lawyer deal with it and spend your energy on making sure your lawyer is doing right by you.
In the end, it will work out ok for you. He is actually scared shitless that you are going to own his balls in the end - as he should be.
