You would need to be more specific. Is this a criminal or civil matter? If it is a criminal matter, then most likely you are thinking of a public defender. If this is a civil matter, and this is an employment issue, then you are thinking of an employment attorney. You need to be a bit more specific though regarding the rights you feel were violated. For the most part, I would suggest calling your local social services office in the county or town that you live in and ask them for advice or where to go for assistance.
