My WAW also mentioned mediation. However, when I spoke with a mediator he suggested that we each retain our own attorney as well. My whole point of getting a mediator was to save $, so we decided to go with one attorney for the both of us as we have sold our house and only need to divide the assets and debt.
Not sure of your sitch or the laws in your statte. Are you civil with your WAW? As you have children involved, it could get complicated. Not sure I am of the greatest help as I have not even filed yet either, but I decided to forego the mediator route.
Good luck.
