I am a material supplier typically hired by a subcontractor or GC. I usually have 0-2 days notice when I am hired to deliver roofing supplies to a job site in Alabama. The Alabama NTO law requires that I must deliver a NTO certified mail return receipt prior to being on site in order to secure lien rights. This is not feasible for my company. Are there any other options available in Alabama for securing payment in this situation (hand delivery of NTO, other options besides lien rights, etc.)?
