Customer returned our equipment damaged, many repairs needed to be made. The customer paid all rentals and now owe us for a Repair Invoice (dated 7/31/18). I requested for an "Intent To Lien" today 9/17/18 to encourage the customer to pay this repair invoice. I want to make sure we're filing this properly to make sure we get paid. What is the deadline to file the "Lien" since this job was in TN? Repairs & Work Order done in PA. Are there any other steps we need to do for this project?
