Louisiana Lien Deadlines for Material Suppliers
Material suppliers in Louisiana have specific rights to file a mechanics lien if they aren't paid. However, Louisiana law requires strict adherence to notice and filing deadlines. If you miss a deadline by even one day, your lien rights may be extinguished forever. This guide outlines the critical steps for suppliers to secure their payment rights.
Public date calculations cover Florida and Kansas. Louisiana dates require qualified review.

Supplier pitfalls
Common Supplier Mistakes in Louisiana
Missing the Monthly Notice of Nonpayment
Many suppliers fail to send the required preliminary notice early in the project, invalidating their future lien rights.
Filing the lien after 60 days
Waiting too long to file. The deadline is strict and often does not extend for weekends or holidays.
Missing the 1-year enforcement deadline
Filing a lien is not enough; you must enforce it (file a lawsuit) before the enforcement period expires.
