Daughter saying she'll run away from dad

[scaredofex]

My 11 year old dd does not want to go to her dad's but has been told she has to go as there's a court order in place. She has refused to go in the past for months at a time which ended up with court applications by her dad, investigations by social services and the end result was she had no choice.
She's at high school now and makes her own way home unless her dad is picking her up. She's saying she's going to give her dad the slip when she's next due to go as she doesn't want to go. I've told her she has to go but she's all too aware that as I'm not there at school that I can't do anything to stop her giving him the slip. She is very unhappy with her dad but social services and the courts aren't listening.
I know where she'd probably go if she didn't go with him which is to a friend's house, not sure which friend though.
What can I do?

At 11 she should be able to tell people what she wants and doesn't want. Has she spoken to anyone at school? Does she have access to a school counsellor?
There are ways out of this, but she will have to speak to people other than you - ideally reputable, experienced professionals who can judge if a young person has been "coached".

The underwear thing is unpleasant. But your DD is unfortunately going to have to speak up for herself. (There is also childline as a starting place.)

She's on the school waiting list for counselling so I'm hoping that helps her.
She is getting better at expressing her unhappiness, bit by bit. She shouldn't have to though. Her dad should prioritise the time he has with them as being for them. Instead the gf's kids come first and they resent that.

Parents should do a lot of things but for one reason or another lots don't. That's not unusual, unfortunately. But having a Mum on her side will help a lot.
Does she get on with her form tutor?

She gets on with her form tutor well and the pastoral care lead is great. Pastoral care are aware of the issues.

The trouble is that even if DD becomes more able to tell DF how she feels, he will always think its you. So I think a return to court is inevitable. But it's important DD is seen as the driving force behind this and absolutely essential she speaks up to the professionals. The worst case scenario is returning to court and DD wimping out. That could be a bad outcome for you OP.

I wouldn't particularly suggests she speaks to her Father about this. BUT if she can speak to other individuals outside the family it will help her fight for the right to reduce contact.

It's better is a teacher can say "Jean told me on X occasions that she doesn't want to see her father for w, u and v reasons". Than "Jean's Mum told me how she doesn't want to see her Father."
Youth workers, Guide leaders etc. can all help.

There is a chance that someone will refer this to SS, but if its coming from her then that is a good thing (probably).

I'm hoping the counselling at school will help her find her voice.
Unfortunately she's reluctant to tell him how she feels so she just "acts normal" and of course he thinks everything is fine.She doesn't want me to be taken to court again so she goes to avoid that.
She doesn't want to go at Christmas now 😩 Lots of reasons but I suspect she's on the spectrum and just isn't coping with the eleventy billion children there and the general business in such a small house.

Beka is right. But if this goes further and DD is interviewed then she has to speak up. It's no good DD saying she wants to see DF to CAFCASS and third parties saying "well this is what she told me" - the latter has more limited value than what she tells CAFCASS (although the judge will have to decide about the opposing evidence and who DD has told the truth to).
Perhaps the school counsellor can help her find a way to tell DF why she is unhappy.
If you think she may be on the spectrum is school referring her for assessment?
