La. Stat. tit. 13 § 3741
In every case where a lost instrument is made the foundation of a suit or defense, it must appear that the loss has been advertised within a reasonable time in a public newspaper and proper means taken to recover the possession of the instrument; provided, that advertisement of a lost note shall not be necessary in any case where a surety bond given by a person who owns property liable to seizure, and who is domiciled in the parish where the security is to be given, or a commercial bond issued by an insurance company licensed to do business in the state of Louisiana, is furnished to protect the maker and/or his endorsers of said note from loss resulting from said note falling into the hands of a holder in due course provided that the bond must be in amount equal to the face of the note plus twenty-five percent thereof.
