My partner's ex is contently breaching family court orders (but has never withheld the children as of yet). She won't give him access to medical records, school records, etc. She is constantly making up false allegations of neglect to try and stop visits, brainwashing the children to put fear into them, refusing to communicate on any important things for the children, rejecting all phone calls and has even told them they can't not bath or eat or be happy in our home and has refused to do some extra mediation (supervised) but has now all of a sudden requested that he mediate with her! We can not do anything until she withholds the children. Is this true and does he have to agrees to mediation now that she has declined so many times? What's the next step?
