What type of attorney is needed for a citation involving a waiter serving alcohol in a restaurant to a minor ?

I would need to review the citation to be certain, but it sounds like this is a criminal summons and that is the topic area you selected, as well.  Therefore, it seems you need a criminal defense attorney. This answer is given in accordance with the laws of Virginia and may not be applicable in any other state.  It should not be construed as legal advice, as that would require a more thorough analysis of all of the facts involved in a specific case.  If you need further information or assistance, please feel free to contact my office for a consultation.
