Can a contractor, a house painter, file a mechanics lein on my property if they've only completed less than 20% of the work after a month’s time and I’ve already paid them 33% of the total agreed amount? Now, the painter had demanded an additional 33% which I said I’d pay when I saw at least 2 days of work progress. But, the painter verbally threatened me to pay at the beginning of the second day vs the end. So, I promptly terminated their work after the threat.
