We finished a Insurance fire claim on a house. We had the Mortgage Inspector come out and it was approved and check was issued. The code office also passed and the customer signed off on the Punch List. When the customer received the last check he would not give it to us although legally he had no right to hold it. He also owes about $25,000.00 more that that. My question is can you go back and do any work on the house after filing a lien on it.
