I am the office manager for a general contracting company. We performed labor and purchased materials with the agreement that all materials would be reimburse and all labor performed by us would be paid. It has now been months and this company has not paid us for everything owed. I sent out a lien notice and have not heard anything, I assume the next step is to file a lien. In order to file a lien, do I need the home owners name and address or do I file it against the company that owes us for the work & material?
