Brace yourself. And lawyers will encourage fights.. the linger it goes on the longer they get paid...
I don't know but do whatever possible to avoid going to court...try to agree upon things, and then have the divorce decree sighned by a judge
Ask the lawyer to give you a flat figure. (They **** me off). Tell him that if he's experienced, he can predict the future, to walk you through the steps, and ask "what's the bottom dollar regardless of what my wife wants" but some how be nice about the way you show walk them thru how you know they already know what's going to happen (they play dumb to get more money) if ultimately XYZ is going to happen, how much. Tell him your price shopping for a final figure.
Play "Columbo" and pose idiot by asking leading questions to corner them if (you have that skill) into telling you from beginning to end what will happen and how much... So line up some pre calls, and go with the one who sounds most direct because they "leave out info" to keep leaching off off you
