That's a question for a lawyer. Nobody else can tell you what your responsibility under the law is.
That said, DickBaker's answer is great. He's pointed you to a place where you can see how others have handled this, and that should at least give you some good questions to ask your attorney.
Sorry, but I shudder every time somebody asks a legal or accounting questions here. In most cases, they already know the answer they want, and will use the answers as a rationalization.
I know many are distrustful of lawyers and accountants, and view a visit to one with about as much pleasure as a trip to the dentist.
I have to say, I have one of each (all three, in fact - even the dentist, LOL) that are knowledgable, reasonably-priced, on my side, and a pleasure to do business with. If this isn't your attitude about your attorney and your accountant, you need to find another one.
