We're in the process of filling out a Mechanic Lien in NYC against a coop owner(s) for failure to pay our invoice. We're an interior paint company that was hired directly by the coop owners. The husband and wife are listed as co-owners according to ACRIS. Is it necessary to file two liens against the wife and husband separately? Or would one lien do? Also, do we need to file a lien against the management company of the building? The building did not hire us.
