ExH ignoring child's health issues

[IndigoInk]

Does anybody know if there's anything I can do to get ExH to do this?

DD has been showing some very concerning mental health issues - self-harming and suicidal ideation.
Children's mental health services in our area were already very stretched even before Covid, waiting lists are months.

ExH has health insurance through work that covers dependents. After initially checking that this would be covered by the insurance (it is) and agreeing to sort out private help for DD, he has been ignoring any communication on the subject for the last 6 weeks and hasn't progressed anything.

I can't afford to pay privately myself.
I'm really desperate to get DD some help asap, is there anything I can do legally?

How old is dd? I think it might be a case of her speaking to her dad about how she needs help asap as it's obvious you're getting nowhere. A lot of people can't afford private, are you sure he still has private health insurance given Covid and firms cutting back.

Yes I am as sure that he still has the insurance - his job is very secure.

DD has spoken to him about it but he just said he's sorting it out.
Much of her anxiety stems from how he treats her so she won't push him further.

I would get her on the nhs waiting list then asap. If Dad sorts it great but I cant see that there is any law you could cite that would force him to act.
