I know this is going to sound a bit koo-koo, but i don't really trust the state to, not just do the math correctly, but to include all of the deductions and additions that are needed to get to the correct number. This is part of the reason we get lawyers, not just to keep things far between the petitioner and defense, but to make sure everything is considered by the Judge. I COULD just leave this to my lawyer, BUT, an informed/prepared client is what makes a good lawyer great
You originally stated you had an original ORDER.
Next time I'm quoting posters.
Now if you bring a modification agreement before the court , the court does NOT have to accept it ,and can make an order of their own.
Have you even done the calculator ?
