My boyfriend has been living with me for over 3 years. We got in fight and he threatened me with contractors/mechanics lien. He has done a lot of work in house, outbuildings and property. However has done so with on site materials and donated material. Walls, electric, etc.. are not up to code. He has also ran 2 trucks and 1 car. Into the ground. I haven't paid him money..but have provided room, meals and cigarettes to him for 3 years. Just wondering if it is even a possibility that he could do this?
