We had arbitration was over a year ago, our agreement did not allow for appeal.
My ex has a lover living in her home, her lover has no other home and all her things are in my ex’s house, they admit they sleep together much of the time, sometimes when the children are in the house, and that they have sex, her lover is at almost every activity involving my children, they exchange presents with her for all birthdays and Christmas, her lover is with her on almost every vacation or trip, including family reunions. They admitted to all of this, but the arbitrator found they were not cohabiting, and did not say why (beyond noting that an arbitrator is given broad discretion).
Given this situation, what would have to happen to bring up the issue of cohabitation again? I believe arbitration is binding even if there are errors in law. I suspect few judges or arbitrators would have found they are not cohabiting. But given the fact that an arbitrator made this decision, does this basically amount to permanent permission to cohabit without fear of consequences?
I think I could have appealed within a very brief period at the time, but it is too late - do those kinds of appeals usually stand a chance?
