I am a sub-sub on a commercial project in CA. Originally, I put in my last day on the job to trigger the lien deadline, but now that's two days away and I'm not sure if I should wait to see if there's been substantial completion or if the Notice of Completion has been filed. I don't want to file the lien too early and damage my relationship with the GC, but if I wait to hear and they never tell me, I don't want to be left unprotected.
