Louisiana Revised Statutes Tit. 9, § 5630. Actions by unrecognized successor against third persons

A. An action by a person who is a successor of a deceased person, and who has not been recognized as such in the judgment of possession rendered by a court of competent jurisdiction, to assert an interest in an immovable formerly owned by the deceased, against a third person, or his successors, who has acquired an interest in the immovable by onerous title from a person recognized as an heir or legatee of the deceased in the judgment of possession is prescribed in two years from the date of the rendering of the judgment of possession.

B. This Section establishes a liberative prescription, and shall be applied both retrospectively and prospectively; however, any person whose rights would be adversely affected by this Section, shall have one year from the effective date of this Section within which to assert the action described in Subsection A of this Section and if no such action is instituted within that time, such claim shall be forever barred.

C. “Third person” means a person other than one recognized as an heir or legatee of the deceased in the judgment of possession.

D. For the purposes of this Section, after thirty years from the date of recordation of a judgment of possession there shall be a conclusive presumption that the judgment was rendered by a court of competent jurisdiction.
