For work done in Alabama, we noticed that the dollar amounts of supplies need to be listed on the Alabama Notice to Owner. If we presume that the amount listed on the letter was the amount that was billed at the time of sending out the NTO, what if more material is billed on this job after the notice goes out? Would that impact our ability to lien for the full amount billed if it is more than what went out on the notice? Second, if we list a contract amount on the NTO for residential work, should the contract amount be used on the NTO, or should we use what has been billed at time of notice?
