Well, I don't know as I want a lawyer to tell me what I cannot do. I hire him to tell how to do what I want to do. ~ J. P. Morgan
Seriously, though: of course the person asking the question should retain a lawyer for definitive guidance. However, asking around to get a feel for the opinions of intelligent people makes sense, too. It might, at the very least, clarify the questions, and it will help detect if the lawyer's words make sense. While attorneys are valuable, they are also fallible, and their advice should be as critically considered as any other.
The danger is that misinformation is often worse than no information at all, and asking a bunch of non-attorneys for legal advice is sure to net you a ton of it.
But some answers are so blazingly obvious or common knowledge that it's worth asking. It might at least speed up a conversation with a lawyer saving many hundreds of $s.
