Louisiana Revised Statutes Tit. 12, § 307. Amended certificate of authority

A. A foreign corporation authorized to transact business in this state shall, by making application therefor to the secretary of state, procure an amended certificate of authority if hereafter it changes its corporate name or proposes to transact business in this state other than that set forth in its prior application. The provisions in respect to the form and contents of such application, the manner of its execution and filing, and the issuance of an amended certificate of authority and the effect thereof, shall be the same as in the case of an original application for a certificate of authority.

B. If a foreign corporation changes its corporate name, it shall include with its application for an amended certificate of authority a certificate evidencing such change issued by the authorized official of the jurisdiction of incorporation of the corporation, or a certified copy of the amendment in the case that the authorized official of the jurisdiction of incorporation does not provide a certificate of such.
