And if enough detail is not specified, confusion could easily result. There are many cases in the history of the law where the two sides to a contract thought they had reached a meeting of the minds, but really hadn't. The moral of this part of the story is that you should be leery of short or idiot-simple contracts for important or expensive things. They may leave a nice first impression, but you shouldn't ever judge either a book or a contract by its cover. The contract that hides the fine print.
Some lawyers are very good at hiding the fine print.
The back of the paper is a good place. That's been tried so many times that many judges will consider that unfair and not enforce the contract, unless the front page refers to the existence of more text on the back. The law presumes that you will realize the importance of putting your signature down on paper and will read through the text that appears before your signature. Another way to hide the fine print is to draw up a long contract and put a key paragraph near the end, at the point where a reader's eyes are starting to glaze over. This has nothing to do with starting a corporation but, rather, refers to incorporating language from another document into the document you are being asked to sign.
