Art. 2855.  Return to order to search for testament

If the notary finds any document which purports to be a testament of the deceased, he shall take possession of it, and produce it in court with his written return to the order directing the search.  The original petitioner, or any other interested person, may petition for the probate of the testament so produced.

If the search is unsuccessful, despite diligent effort, the notary shall make his written return to this effect to the court.
