Imagine playing a game of cards without specific rules. It would be impossible for any player to “win” as nobody truly understands how the game is played. It wouldn’t be a lot of fun and players would likely argue about who’s right and who’s wrong.
Sadly, many poorly-written agreements regarding the latter come from using online “legal” forms. You’ll notice we put the word “legal” in quotations as using generic forms rarely protects your legal interests. The truth of the matter is that no generic form can address all the nuances of your business.
