Louisiana Revised Statutes Tit. 12, § 1-203. Incorporation

A. Except as provided in Subsection C of this Section, the corporate existence begins, and the corporation is duly incorporated, when the articles of incorporation become effective under R.S. 12:1-123.

B. The secretary of state's filing of the articles of incorporation is conclusive proof that the incorporators satisfied all conditions precedent to incorporation and that the corporation is duly incorporated, except in a proceeding by the state to cancel or revoke the incorporation or involuntarily dissolve the corporation.

C. When immovable property is acquired by one or more persons acting in any capacity for and in the name of any corporation that is not duly incorporated, and the corporation is subsequently duly incorporated, the corporate existence shall be retroactive to the date of acquisition of an interest in the immovable property, but such retroactive existence shall be without prejudice to rights validly acquired by third persons in the interim between the date of acquisition and the date that the corporation is duly incorporated.
