Just for the sake of discussion-----What would you expect the sheriff, state attorney or DFCS to do about it?
This is going to boil down to the quality of your evidence, the presentation of your case and the judge that rules on your case. While there are certain instances where law enforcement might get involved, that is going to be for crimes and not civil contract enforcement, which is basically what we're talking about. Same for the states attorney. ROFR violations are not a crime. DFCS is chartered to save. They have crackhead babies getting raped to deal with as well as all the false reports of women claiming the kids father abused them. ROFR violations are not on their radar.
I know it sucks. You finally get what you want in the order and think things are finally going your way and damn if she didn't throw a wrench in it already. It blows.
It's a battle of wills. Gather your evidence and drag her back again. Eventually, one of you will break. We will be here to cheer you on until you break her.
