The lawyers play their games to get as much cash from two emotional people as possible.
You have handled this sitch better than most here.
I feel for you. I am not a law expert, but I know there are claims/counter claims and objections. Many people settle without being ordered by a judge which then becomes the legal order.
I read all the child support and divorce statutes here in CO. I was going to hold hard during some of my later negotiations, but then I got "pro-se" written into the agreement. I bent on the child support to get the lawyers out future negotiations.
I recommend doing as much research as you can. Lawyers also play with words. Find legal definitions of income. Find other cases. I am just throwing ideas out there.
