Corporate bylaws are required by state law in New York, but you don't need to file your bylaws with the NY Department of State. The law stipulates that your bylaws must be adopted by your incorporators during your company's initial organization meeting.
Corporate bylaws are a company's foundational governing document. They lay out how things should run day-to-day and the processes for making important decisions. They serve as a legal contract between the corporation and its shareholders, directors, and officers and set the protocol for how the organization operates.
