Louisiana 70-Day Filing Deadline from Substantial Completion
Under La. R.S. 9:4822, all mechanics lien claimants — general contractors, subcontractors, sub-subcontractors, and material suppliers — have 70 days from the substantial completion or abandonment of the work under the prime contract to file a Statement of Claim or Privilege with the parish Clerk of Court. If a Notice of Termination of Work was properly filed, the 70-day clock runs from that filing date instead. The critical distinction from most other states: Louisiana's deadline runs from project completion, not from the individual claimant's last date of furnishing. A subcontractor who last worked on the project several months before substantial completion still has the same 70-day window that runs from the overall completion date.
Louisiana's Notice of Contract System
Louisiana's Private Works Act includes a Notice of Contract framework that most other states do not have. Under La. R.S. 9:4811, an owner and prime contractor may file a Notice of Contract with the parish Clerk of Court before construction begins. When a Notice of Contract is filed, subcontractors' and suppliers' privileges attach through the recorded contract and the owner's liability to pay subcontractors is capped at the unpaid balance owed to the GC. When no Notice of Contract is filed, the owner may have personal liability to subcontractors and suppliers for the full amount owed under La. R.S. 9:4812.
Where to File in Louisiana — Parish Clerk of Court
Louisiana mechanics liens are filed with the Clerk of Court in the parish where the improved property is located. Louisiana uses parishes instead of counties — there are 64 parishes. Major filing offices include Orleans Parish Civil District Court (New Orleans), East Baton Rouge Parish Clerk of Court (Baton Rouge), Jefferson Parish Clerk of Court (Metairie/Kenner), St. Tammany Parish Clerk of Court (Covington/Mandeville), Calcasieu Parish Clerk of Court (Lake Charles), and Caddo Parish Clerk of Court (Shreveport). Always file in the parish of the property address.
Louisiana 1-Year Enforcement Deadline
Under La. R.S. 9:4833, a claimant must file suit to enforce the Statement of Claim or Privilege within 1 year of the date the Statement was filed with the parish Clerk of Court. This is a hard deadline — courts will not extend it. If no enforcement action is commenced within 1 year of the filing date, the privilege expires automatically and the property is freed from the encumbrance. The Mechanics Lien Management Method recommends tracking the enforcement deadline from the day of filing, not waiting until payment negotiations stall.
