I got a text from her pleading we not go through this process, nor mediation.
Ummm....if you don't even use mediation, what are you gonna do - write down a settlement on a paper sack?
Now - if she REALLY doesn't want to go through it, you COULD say "Ok, we'll use my attorney" and write up something that super favors yourself and see if she'll sign. But honestly, when children and child support and custody are involved, it's be foolish to do this without you both having attorneys, whether through mediation or otherwise.
What is it you think you might find through discovery? Did you not have a good grasp on her finances when you were together?
