My cofounder typically vets any contracts that are drawn up with a personal lawyer. We started out with a fixed equity split, but we agreed in principle to move to a dynamic equity split a la Slicing Pie. I worked with a slicing pie lawyer to have a slicing pie boilerplate drawn up. My cofounder's lawyer conceptually just doesn't seem to grasp what's going on at all, and his influence over my cofounder is such that my cofounder is starting to doubt dynamic equity splits altogether.
Has anyone encountered this type of scenario? How have you dealt with attorneys who are clueless about dynamic equity splits?
