I am in the state of Texas, we are a subcontractor to the general contractor who is contracted with the owner directly. Since our projects go on for a few months in the commercial realm, and I have already sent the notice out did one of the months we are owed for, do I file the lien for just that month or the months following that as well even though they are technically not “past due” yet and we have not sent the notices out for the following months, as they would be due this month.
