Not always, honey bunny.
In case you missed it, @adlawguy's advice from last week's AdVerve e-newsy was "Don't Put It In Writing." It cites the one time in your creative career you should think twice before leaving a paper trail behind. The situation isn't as rare as you'd think, and it's good to keep in mind, especially in these creatively derivative times. :P (Former guest Joe La Pompe can talk to you all about that subject.)
A snippety-snip:
While most lawyers will rightly tell you to put everything in writing, there is one area in which you definitely want to think twice about leaving a paper trail.
When I get an email that says “We want to do a take-off on Star Wars, can we do it?”
My immediate response is "Not anymore."
