I am an attorney in New York representing an architect who had a mechanic's lien filed through Levelset. My client the architect is now involved in a AAA arbitration proceeding against his client, a co-op unit owner in New York, and the client/co-op unit owner is claiming that the lien is illegal as it has been placed on the entire co-op rather than just the individual unit (i.e., shares in the co-op?). Can you please advise if the lien is still valid, and whether it can be amended to be placed only upon the individual unit owner's premises/shares. Also, can you point me to any type of legal authority that I might use to argue the lien is not invalid and/or merely needs to be amended? Thank you.
