Dsc are 8&9, mum has never been supportive of contact. They have a contact order which she's breached numerous times. She demands to speak to dsc twice daily and will repeatedly ask them if they're ok or if she should come and take them home.
A couple of months ago, one of the dsc did something which endangered our other dcs life. Dp barely reprimanded them but dsc rang mum, demanded to be collected and said dp had shouted and screamed at her for an hour. They went home today and dsd has apparently told her mum that dp sat on her, shouted in her face and held her neck and mouth so she couldn't scream or shout. No such thing happened - there was no fall out whatsoever.
Mum rang dp and said he'll have to take her back to court if he wants to see them again because he's abusing them. Both children said these (and other) things have happened both to mum and to dp on the phone.
Where do we go from here? If we pay to return to court and both dc tell cafcass this is true, surely contact will remain stopped? But if we don't, it looks like an admission of guilt and dp loses his kids. Has anyone been in a similar situation and could advise?
