Louisiana Revised Statute § 38:2247 requires a subcontractor not in privity with the general contractor (i.e., a sub-subcontractor) to provide notice to the general contractor by certified or registered mail sent to the general contractor’s Louisiana office. The district court found 84 Lumber, who did not have a contract with the general contractor, failed to give proper notice of its claim to F.H. Paschen when it emailed the notice to the contractor’s attorney. After observing that the Louisiana appellate courts have reached conflicting conclusions, the U.S. Fifth Circuit held that the statute does not say anything about “actual notice” and, therefore, neither sending notice by email nor sending notice to a general contractor’s lawyer is sufficient notice. Because the LPWA is strictly construed, the sub-subcontractor’s failure to send notice via registered or certified mail was fatal to its claim.
