We have encouraged you to remove yourself completely from H's communications regarding legal matters, proposals, and what not.
Here's a suggestion: H,
Thank you for your email.
I am passing this on to my attorney to review. For future communications regarding asset divisions, divorce, and other pertinent matters, please direct all of these communications to my attorney. Please ensure that all communications are directed to him/her going forward from today and on.
I will not respond to any of your further emails that do NOT relate to the children's activities.
Working together on the co-parenting aspect in terms of school schedules, health issues (flu, stomachache, etc), clothing items, parent meetings is something that we will need to do here for KidName and KidName.
I agree that trying to get along with one another will be good for the kids.
