As the sibling comment points out, it's not like you can hire any lawyer off Craigslist and expect to be bulletproof.

Lawyers can be an expensive rubber stamp on a deal that is absolutely not in your interest or be a chaos agent that makes you impossible to do business with. They can also make executing complex deals very simple (for you) or ward off sophisticated scammers. At least in my experience, it can be very hard to know which is which before it's too late.
