Louisiana Revised Statutes Tit. 31, § 210. When purchaser protected in paying party in interest under lease for minerals produced

A purchaser of minerals produced from a recorded lease granted by the last record owner holding under an instrument translative of title to the land or mineral rights leased is fully protected in making payment to any party in interest under the lease unless and until a suit is filed testing title to the land or mineral rights embraced in the lease and the purchaser receives notification of it by registered mail.  The purchaser is not entitled to this protection unless he has filed for registry in the conveyance records of the parish in which the land subject to the lease is located notice that the minerals produced have been and will be purchased by him.
