We worked as the sub-sub for a subcontractor on a Texas project. We are a staffing company that provides labor for jobsites. Back in August, the subcontractor relocated our workers to another jobsite, but did not notify us. We continued to bill the hours to the initial jobsite for a few months hours, as we were unaware our workers were relocated. We are approaching a lien deadline for the initial project as we have not been fully paid for the labor we supplied (the customer agreed to an installment plan but there is still a large amount outstanding due.) If we wanted to proceed with filing a lien for this work, on what property would it be filed? Where our workers started, or where they were re-directed, or both?
