Send her a copy of that page of the new agreement and highlight that receiving parent is to pick them up. Next time, if she does not pick them up, you keep them until she does. Always have your agreement ready for when she calls the police. They will tell her to come get them. As for the kids, just tell them after you get them, that the new judges rules are that that parent that is getting them, come pick them up and that the adults will handle it. Guess she really did not read the new order.... See what happens the next time before taking it to court.
