Legal aid is normally available for these cases if you are not working, are on a very low income, or have high financial commitments.
Legal aid usually gives you an insurance against paying the legal costs of the police if you lose. Law Centres who do this kind of work may do so for free if you cannot get legal aid. If you lose your case and are not legally aided you will probably have to pay your legal costs. These may be quite high so check this out before you start your case.
If you are not eligible for legal aid and if you have a strong case you may be able to get a solicitor to agree to take it on a ‘no win no fee’ basis. This is also known as a conditional fee agreement (CFA). With recent changes in legal aid making it more difficult to get funding for civil claims, a conditional fee agreement (CFA) is becoming more widespread and is something you should speak to a solicitor about.
