Corporations commonly adopt bylaws as part of their organizational process, and state corporate law may contemplate or require them. Bylaws generally remain internal rather than being filed with the formation agency.

Bylaws are internal governance rules and are usually kept with the corporation's or nonprofit's records rather than filed as the public formation document. They commonly address meetings, voting, director or officer authority, committees, and procedural rules. The contents should be consistent with applicable state law and the organization's Articles or Certificate of Incorporation.

Corporations commonly use Articles or a Certificate of Incorporation, bylaws, initial organizational actions, officer and director records, and stock or shareholder records. The state filing establishes the entity, while these internal records help document how the corporation is governed and who has authority to act for it.
