Louisiana Code of Civil Procedure Tit. III, Art. 3393. Reopening of succession

A. After a succession representative has been discharged, if other property of the succession is discovered or for any other proper cause, upon the petition of any interested person, the court, without notice or upon such notice as it may direct, may order that the succession be reopened. The court may reappoint the succession representative or appoint another succession representative. The procedure provided by this Code for an original administration shall apply to the administration of a reopened succession in so far as applicable.

B. After formal or informal acceptance by the heirs or legatees or rendition of a judgment of possession by a court of competent jurisdiction, if other property is discovered, or for any other proper cause, upon the petition of any interested person, the court, without notice or upon such notice as it may direct, may order that the succession be opened or reopened, as the case may be, regardless of whether or not, theretofore, any succession proceedings had been filed in court. The court may appoint or reappoint the succession representative, if any, or may appoint another, or new, succession representative. The procedure provided by this Code, for an original administration, shall apply to the administration of successions formally or informally accepted by heirs or legatees and in successions where a judgment of possession has been rendered, in so far as same is applicable.

C. The reopening of a succession shall in no way adversely affect or cause loss to any bank, savings and loan association or other person, firm or corporation, who has in good faith acted in accordance with any order or judgment of a court of competent jurisdiction in any previous succession proceedings.
