Articles of association

In corporate governance, a company's articles of association (AoA, called articles of incorporation in some jurisdictions) is a document that, along with the memorandum of association (where applicable), forms the company's constitution. The articles define the responsibilities of the directors, the nature of business, and the mechanisms by which shareholders exert control over the board of directors.

Articles of association are essential to corporate operations, as they may regulate both internal and external affairs.

Articles of incorporation, also referred to as the certificate of incorporation or the corporate charter, is a document or charter that establishes the existence of a corporation in the United States and Canada. They generally are filed with the Secretary of State in the U.S. State where the company is incorporated, or other company registrar. An equivalent term for limited liability companies (LLCs) in the United States is articles of organization.
