In Mass can a mechanics lien be filed 1 1/2 years after the completion of the work? We had new windows installed and the work was completed in August, 2018. The contractor says we still owe him more money even though we paid what he quoted us. He will not meet with us to resolve this matter. Can he still file a mechanics lien at this time? Does he have to go to court to do so? If he can will I be notified before it would be filed?
