My General Contractor "disappeared" sometime in October/November of 2022. I later found out he declared bankruptcy. In December, a subcontractor of whom I was unaware, submitted an invoice for work he said was performed on my home. Most of the wok was very poor, but some of it was extremely dangerous, e.g., a solid wood fireplace mantle was installed with two small screws and could have easily fallen on someone; an open stairwell on the second floor was completed without a railing or any safety measures which easily could allow an unwary party to fall over 10 feet. A Sub also submitted a bill and filed a lien for painting for an inordinately excessive number of hours given the size of my home. Is my understanding correct in that I acknowledge the liens, but then later bring an action for Breach of Contract against both Subs?
