Hi there - you might check out the FLAC guide to the civil legal aid system at their website flac DOT ie FORWARDSLASH publications FORWARDSLASH civil-legal-aid-flacsheet (I cannot post URLs apparently!)
Might be of some use in explaining how the civil legal aid system works.
You should also note that civil legal aid and advice, unlike criminal legal aid, is not free. There is always a contribution. Also, you will only get a certificate when you pass the means and merits tests, and it is likely that this consultation with the solicitor will be where her case's merits will be fully examined.
All the best
