So, our last day on the job was 4/28/20. We had issued a Change Order for work completed prior to that date. The change order was just approved on 7/9/20 by the contractor and added to the contract amount. Does that make the "final furnishing" 7/9? I was going to file a Claim of Lien today 7/20 to fulfill our lien rights based on the 4/28 date, so an answer to this question as soon as possible would be very helpful.
