My firm is a materials supplier for large construction projects. I have been told that if the property ownership has paid their GC in full for the project, if an electrician owes us for materials and we lien the property then my firm's lien would be deemed invalid. IS this true?
The lien would not be invalid, per se, but if it turns out there is no "lien fund" then there will be no recovery. However, if there is no lien fund because your upstream contractor was paid, but payments did not flow down to you, there may be an issue relating to a diversion of statutory trust funds. You will want to serve a Demand for Verified Statement of Trust, as was suggested above, to see what happened to the money.
