The GC on our project will email us to ask if we have been paid for the work that was completed during the month by the sub (we are the sub-sub). They have now emailed us saying the sub informed them we have been paid in full for this project and asked us to confirm. We want to maintain a good relationship with the sub that hired us and know they cannot pay us until they have been paid, but also do not want to reply "yes" to the GC's email and have that potentially hurt our lien rights if for some reason the sub does not pay. Could replying and saying the sub has paid us in full in anyway negate our lien rights, or (as long as we don't sign a lien waiver) are we ok?
