One thing, if you made an agreement and had someone sign it, what would happen if you just edited it a little afterwards, assuming the "victim" doesn't have a copy?

Or if the person does have a copy, what would happen if he just decided to play around with his agreement some by removing some things from it, and then trying to sue the other person who was involved in the deal. When you compare the documents, you are most likely to win, since you could accuse the other person of adding print to his paper.
