You may be able to get free legal aid to cover your Court action. You will need to make a formal application to the Legal Aid Board, and you will need to provide some financial information to show that you are not in a position to pay for the hearing. Once you have been told that you have qualified for legal aid, you will be given a list of the solicitors who you can engage to represent you in Court.
If you have not qualified for legal aid, you should contact a solicitor and get a quote from them to deal with the matter privately.
