A contractor threatened us with a lien over a month ago but has not filed one. They walked off of our job on a 203k loan on a two family renovation. We do not agree with what they have been paid nor what they’re demanding to be paid on E.g. they received 10,000 for a “new” roof in which the roof still leaks, and another 9,000 in plumbing for which a plumber told us there are at least 4 code violations that need to be addressed prior to inspection. How long do they have to file? And can we expedite the process?
