We were working with a contractor on a home addition/remodel. We had no written contract with the builder (friend of family) and due to their not following through with so many things we had no choice but to call the project off. Their architect, who we never had any direct contact with, filed a mechanics lien on our property. He sent me an email telling me that if we didn't pay him he would file a mechanics lien on our property the next day. He followed through and filed the lien. From my understanding that wouldn't qualify as proper notice of intent, would I be correct in assuming that the lien would be considered invalid?
