I am in the construction industry ( a construction monitor for lenders) I have been told that "In accordance with North Carolina statues, the Subcontractor CONDITIONAL lien waiver automatically becomes UNCONDITIONAL after 60 days, provided no liens have been filed by the Subcontractor." Is this true? what are the unconditional lien laws in the State of NC. I am from Florida, and if a subcontractor has not been on site for 90 days, they release all lien rights.
