Wife has Atty - Do I have to go through her Atty now?

STBX has an Atty, I do not.
We have custody worked out.
Her Atty & I was working on Equitible Distribution.

My STBX insists I go through her Atty for any parenting items, like scheduling, following the rules in the custody/parenting plan.

If we have custody/visitation worked by court order, do I have to go through her Atty for those issues ?

There is no requirement that you not have contact with your ex, however going through her lawyer may be a better option if she refuses to discuss issues with you as they arise.
