We hired a landscape contractor to put crushed granite & flagstone in our backyard. We paid him (by check) for the first part of the down pay on work. And when he finished we paid by check the final bill. He provided us with an invoice stating the materials, labor, My 2 check payments and final bill paid off. Contractor used a company in town called "Texas Rock & Flagstone" to purchase our materials. The job was finished on June 14 this year. Yesterday, I received a letter form the rock & flagstone company stating they never were paid by the contractor & that I have till October to pay them for the rock & flagstone or she would turn 'Me' into collections. I called the rock place, she said the contractor told her "I wouldn't pay for the job", she also told me she could put a lein on my house. I told her I paid for the entire job & that i have to both checks from the bank where I paid the contractor in full . The rock lady also sent me the 2 invoices that are billed to the landscape contractor. She also told me the landscape contractor had already owed her $600 from a previous job. What is my legal right in this matter? I keep trying to contact the contractor and he wont answer my calls. I traced down his address the rock lady had on his invoice, it was an apartment & they said this guy ran out on them a long while back and owed them a lot of money.
