I spent 14 months between October, 2018 and November, 2019 acting as a General Contractor for someone building two shops on his property. In November, 2019 as the job was completed he brought someone else in and terminated my employment without paying me for my work. He drew up a promissory not to promise to pay me $50,000.00 at $5,000.00 per month starting in November of 2019 and each and every month following until the balance was paid in full. He made 3 payments and stopped paying me in January of 2020. I have sent several letters and emails to him with no results. His excuse for not paying me is that "His wife passed away from Covid 19 in 2020 and he doesn't think he owes me or the world anything and does not care what anyone thinks. He still owes me $35,000.00 along with $9,876.00 worth of tools and equipment I was not allowed to take with me when I left. I was told that I was entitled to file a "Constitutional Lein" in the State of Texas for up to 4 years against this property. That is what I would now like to do. Please advise
