When (not if) we decide to part ways, how will we do that?

Best advice I ever got was from our lawyer during the formation of our C-corp when we outgrew our partnership: "It's important to decide how you will split up now, while you are still friends, because when the time comes to split up, you may not agree." So true.

While I give him credit for this advice, lawyers in general are overpaid and not usually very reliable in my experience. This same lawyer gave us our corporate papers printed with some other company's details, including their bank account information.

Don't put too much trust in a lawyer unless you have a lot of experience with them to back up that trust.
