in my residential neighborhood (the adjoining property owners located on each side of my property) where 1 of the homes has not been lived in for over 20 years and the other property is a vacant lot; ive had no contract or contact with either of the owners for the past 15 years, but ive been providing year round lawn services to both properties on a regular basis for 15 years straight. Can i file a mechanics lein on the properties for the lawn maintenance and upkeep of the properties large yards?
