We are the General Contractor on a private commercial project in TX. I am not finding clear information on deadline for us to file our lien. 15th day of 4th month following last providing, which includes punchlist and change order work?? So if done the 6th of July, we have to have recorded by 11-15-18? Also, are liquidated damages being held on us that we are disputing to be included in our value as well as change orders not yet provided for work completed?
