An Oklahoma Amended Certificate of Incorporation is a document that is filed with the Oklahoma Secretary of State's office to update or amend the formation of a domestic corporation. It is used to make changes to information regarding the company's name, purpose, number of shares authorized, and corporate structure. There are two types of Oklahoma Amended Certificate of Incorporation: one before receipt of stock (profit) and one after. The amended certificate of incorporation before receipt of stock (profit) is used to make changes to the company's information before any stock is issued or profits are generated. The document must include the name of the corporation, the date of the amendment, the original date of incorporation, the purpose of the corporation, the number of shares authorized, and the names and addresses of the directors. Any changes or amendments to the company's information must be approved by the shareholders or directors prior to filing.
