We are a mechanical contractor, we do HVAC We have a situation with one of our customers. Builder, for new construction. They have several homes and their account is currently past due. In one their jobs on of our sucobtractors (they're insured) they made a mistake and some damages needed to get fixed. The problem is that out customer said he was going to send us the documentation so we could open a claim with the insurance. The never did that and now they are just trying to substract 12K from all the open invoices they have. My question is, can we file a lien for one of their houses, since the amount matches with one of their jobs.
