Legal Advice and specialist counselling for ASD and trauma

My adult child has been accused of breaking a University Students Code of conduct and banned from attending the any events and all societies. They have been traumatised by these allegations and the manner in which they have been delivered. I am now looking for specialist legal advice regarding disability and discrimination,as well as finding counselling for my adult child from someone aware of ASD issues and trauma. 

I am also looking for support as a parent on how to help and support my adult child through this traumatic process of what feels like a student union trial/disciplinary process.
