I'm a GC and we hired a contractor to do substantial grading work for us on a residential project. He overcharged us and we clearly demonstrated that he had done so and also that he did not follow the engineering for the project. We explained this to him and attorneys got involved. At this point, we are 5 months and 1 day past the last day he did work for us. My concern is for my client. My understanding is that he needed to file a notice of intent by yesterday and since he did not, he losses his right to file a lien. Is this correct?
