For one, Florida law requires that all corporations have corporate bylaws. According to FL Stat § 607.0206, the incorporators or board of directors must adopt initial bylaws of the corporation unless that power is reserved to the shareholders by the Articles of Incorporation.
Just as important, though, is that writing corporate bylaws is critical to running your business smoothly and efficiently. For example, every corporation must appoint directors and corporate officers (President, Secretary, Treasurer, etc.). The bylaws are where their duties will be explained. Even simple procedural issues, such as when and where the annual shareholders meeting will be held, are addressed while writing corporate bylaws.
