Delaware Code
Subchapter II. Formation
§ 1521. Certificate authorizing transaction of business.

A certified copy of the certificate of incorporation and of the articles of organization and the endorsement of the approval of the State Bank Commissioner shall be filed with the State Bank Commissioner; and when the whole capital stock has been issued, the president and the cashier or treasurer of the corporation shall certify the names and addresses of the stockholders and the number of shares owned by them. Upon receipt of such certification, the Commissioner shall cause an examination to be made of the method of payment of the capital stock and if, after the examination, it appears that the whole capital stock stated in the articles of association has been paid in cash, and that all requirements of this Code and any other applicable law have been complied with, the Commissioner shall issue a certificate authorizing the corporation to begin the transaction of business. No corporation shall begin the transaction of business until a certificate has been granted authorizing it to do so.
