I'm establishing a startup. What financial/legal documents should I have?

Do you have to consult with a lawyer? Absolutely not. Are you insane if you don't? Probably. As a lawyer who deals with start ups in the IP area I am biased of course. However, it would help to know if you have partners. What you intend to do with your business 5 or 10 years down the road (i.e. sell it off or take income from it). Whether you're getting investors and what kind. It's more than just the documents that an attorney provides. If you'd like to discuss further, I'd be happy to speak with you.

You might indicate which country you are now, where you want to sell your products etc.
Before going to the lawyer, try to answer questions posted by Adam Hirshfield yourself. This way you will look more professional and ... you wont be charged for answering those questions :)
