Also found in: Dictionary, Legal.
slang An inmate of a prison or jail who is or has become knowledgeable enough about the law to provide legal advice or representation to themselves or others. I couldn't afford to hire a lawyer, and the state was too slow providing me with one, so I had to rely on a couple of jailhouse attorneys I met in the slammer to help me file my appeal. I really would recommend hiring a real lawyer. You shouldn't be basing your case on what some jailhouse attorney is telling you.
