La. Code Civ. Proc. art. 4607
When a partition is to be made by licitation, the sale shall be conducted at public auction and after the advertisements required for judicial sales under execution. When a partition is to be made at private sale without the consent of all co-owners, the sale shall be for not less than the appraised value of the property, and documents required pursuant to a court order shall be executed on behalf of the absentee or nonconsenting co-owner by a court-appointed representative, who may be a co-owner, after the advertisements required for judicial sales under execution are made. All counsel of record, including curators appointed to represent absentee defendants, and persons appearing in proper person shall be given notice of the sale date. At any time prior to the sale, the parties may agree upon a nonjudicial partition.
