I'm a customer of Petersen Dean and paid them in full to complete a solar job in Southern California, which included exdtra $$$ for an electricaly panel upgrade completed by a subcontractor. PetersenDean took the exta $$$ but did not oay the subcontractor. The subcontractor is attempting to place a lien on my home (I received 20-day notice) and we (me and subcontractor) have no written agreement and i did pay for their work thrugh PetersenDean, which filed Chapter11 last week. What can I do to protect my property considering I am completely innocaten and have paperwork to show I paid for the work already?
