Louisiana Code of Civil Procedure Tit. II, Art. 3669. Possessory action unavailable between owner of mineral servitude and owner of dependent mineral royalty

In the event of a dispute between the owner of a mineral servitude and the owner of a mineral royalty burdening or alleged to burden the servitude in question, the possessory action is unavailable to either party, and the only available real action is the petitory action. The burden of proof on the plaintiff in such an action is that which must be borne by the plaintiff in a petitory action when neither party is in possession.
