This is what the solicitors’ regulator, the Solicitors Regulation Authority has to say about bogus solicitors (see http://www.sra.org.uk/consumers/problems/fraud-dishonesty/bogus-fake-solicitors.page)
It is a criminal offence for someone to call themselves a solicitor or act as a solicitor if they are not on the roll of solicitors. We call these people “bogus solicitors” and we may prosecute them. We publish alerts about bogus solicitors.
