I expect the bar association will say that a lawyer is needed.
Not a bad assumption, but if the question is asked correctly, then the OP should be able to get the information he needs, rather than the canned response.
E.g.,
Q1: "Should a lawyer or patent agent prepare a patent application?" Likely Answer: "Absolutely."
Q2: "Under the rules governing professional ethics in this state, am I, a non-lawyer, legally able to prepare a patent application for my friend, provided that my friend signs all the paper work and files the application himself?" Possible answer (not saying this is correct): "Well, nothing in the state rules bars you from doing that, but it would be better if an attorney or agent did what you are proposing."
In sum, the question should be framed as "Can I legally do X?" not, "Should I do X, or should I get an attorney/agent to help me out?"
