By Sarah E. Needleman When starting a business these days, it may be wise to document the role played by everyone who helped you get it off the ground. Should your company become a raging success, chances are some of those folks will try to seize a piece of your fortune in court. Perhaps Facebook co-founder Mark Zuckerberg wishes he’d done this.
