"I have my judicial review at the High Court in June".
That's good news.
You would be well advised to be represented at the review, and depending on your personal circumstances you may be eligible for public funding - it's what used to be called Legal aid. It is now dealt with by the Legal Services Commission, and they need to be satisfied that your case has a good chance of success before they will grant Public Funding. You might want to talk to a solicitor who does this kind of work, because if you are going to be represented at the review you'll have to obtain what's called a 'Legal Representation Certificate'.
I suggest that if you need help with Public funding you contact Community Legal Services on 0845 608 1122. They'll be able to provide details of legal advisers in your area who can help.
