Form Design Theory

I'm developing a program for my father's real estate law office. He wants the primary form to contain ALL of the information that has to be entered on one long form that you use to scroll down (he has his valid reasons for doing so). However, I'm also developing this product for law offices in general (a number have expressed interest) and I think that this method of having all of the information on one form (vs. having tabs on that single form) is a bit unordered. Is there a standard way of designing forms - perhaps a rule that says forms should not take up more than one screen in length (and therefore need the scroll down option?).

Thanks,
