I had a painter come work for me on my private property. Contract was agreed for $1200 for the painting project and half was due upfront which I paid. Painter left most of the work undone and refused to come complete the job he initially agreed to claiming it was more work than he thought (Contract was sent by him endorsing the nature of the Job) I have sent him pictures of undone work yet he claims that he wants to file a construction lien on my property knowing my house is coming up for sale. (Painter has also expressed interest in purchasing my house and even brought his family over for a walk-through) I am having to contract the remaining of the work over to another painter since he has refused to return to complete the work. What can I do in this case?
