About the questions on the Killer Contract and its real-life application, Andy Clarke personally told me that in five years, no client ever questioned the legality of the contract or made objections. In most cases, the whole signing process was actually speeded up by using a shorter/simpler contract. I believe no plain-English contract will create problems with small / mid-sized clients. Worst case scenario, you lose the “battle of the forms” and end up having to review the client’s template.
It is true that Andy’s model has a lot of personality, and that personality simply might not work for you. There’s no shame in using a more classic example, just make it work for your particular project. Coming up with your own template is not easy work (and I think I made it clear in the article), but the benefits in the long term can be huge. It’s almost like an investment in a technological tool that’s hard to master at the beginning, but can boost your productivity for years ahead.
