This post is based on a question that I answered on OnStartups. Q. I’m in the process of closing a deal with a new client, and the only sticking point is the choice of applicable law. I am located in state A, the client in state B. My contract says it will be governed by the law of state A. The client wants to change this to New York. Why? Would doing so open my company up to any unintended side effects/liabilities (e.g., taxes)?
