A copy of the sheriff's act of sale or property sold at judicial sale, certified by the clerk of court, is full proof of all of the recitals of the original act.
When the original act of sale is lost or mislaid before it is registered in the conveyance office of the parish, and a person interested in having the sale registered submits an affidavit that the original act has been lost or mislaid, the sheriff who sold the property, or a successor in office, may execute and issue, nunc pro tunc, another act of sale which may be registered in the conveyance office with the same effect as the original act. A copy of this duplicate act certified by the clerk of court is full proof of all of the recitals of the original act.
