Louisiana Code of Civil Procedure Tit. III, Art. 3282. Publication

Notice of the application for authority to sell succession property at private sale shall be published at least once for movable property, and at least twice for immovable property, in the manner provided by law. A court order shall not be required for the publication of the notice.

The notice shall be published in the parish in which the succession proceeding is pending. When immovable property situated in another parish is to be sold, the notice shall also be published in the parish in which the property is situated. When movable property situated in another parish is to be sold, the notice may be published also in the parish in which the property is situated, without necessity of a court order for the publication; however, the court may order the notice to be published in the parish where the movable property is situated.

The notice shall state that any opposition to the proposed sale must be filed within seven days from the date of the last publication.
