La. Stat. tit. 41 § 713
Before selling the school lands belonging to the state, the parish treasurer, or other persons whose duty it may become, to superintend the sales, shall cause a resurvey of the lines which from any cause may have become obliterated or uncertain; and for this purpose he may employ the parish surveyor, or on his default, any competent surveyor. The lines thus surveyed shall be marked in such manner as to enable those interested to make a thorough examination before sale, and all advertisements made for the sale of the lands shall contain a full description thereof, according to the original survey and that required by this Section. The expenses of making the survey shall be paid by the State Auditor out of the proceeds of the sale of the lands on the warrant of the parish treasurer.
