You need to return to the court that issued the visitation/custody order and make a motion to modify the order based upon what occurring. Unfortunately, these types of things happen all of the time in these situations and unless you can prove by expert evidence that the statements he is making is causing the children extensive emotional harm, the court will merely admonish him not to make such statements and continue the order without change. Therefore, if you believe there is significant emotional damage being done, you need to take the children to a licensed professional for evaluation to present the evidence to the court.
