If say in Arizona, our lien rights are based off of substantial completion our retention payment should be covered under that time line right? But what about a state where rights expire based off of our last day on site? Our lien rights expire before we receive our final retention payment? Do we then lose our rights to that? Or is it because it was retention from time previously on site is it always covered? And how do we go about filing a lien to a GC on our final payment if our rights have expired?
