The general field is administrative law, the narrow niche is university and college disciplinary matters. But what (and who) you need is defined by what you are facing. Are you faced with charges of inappropriate conduct? breaches of any code of student conduct, academic, social, etc.? If not, you may not need an attorney at all. I am always uncomfortable when people go before any kind of tribunal because I know that, no matter what you say, it can backfire and become ammunition against you in a subsequent proceeding. So, less is more? Can you hew to that?
My responses to questions on Avvo are never intended as legal advice and must not be relied upon as legal advice. I give legal advice only in the course of an attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by individual consultation and execution of a written agreement for legal services.
