We successfully represented an architecture firm in a complex mechanics lien claim involving a vertically subdivided property. Unlike horizontally subdivided properties, where ownership boundaries are typically straightforward and two-dimensional, vertically subdivided properties present unique three-dimensional complexities. Different entities have varied but shared interests in many parts of a single structure, spanning multiple floors and encompassing various uses. This demands precise identification of the correct interest to ensure a lien’s validity. Here, the property comprised a mix of retail, residential, hotel, and entertainment spaces, each with its distinct ownership entities, but with shared legal interests in things like structural steel beams which penetrate them all. We analyzed surveys, title reports, and recorded documents, undertaking a three-dimensional analysis of the property to describe with pinpoint accuracy the unique and shared interests of the entities who owed our client some $1 million for professional services rendered. This ensured the mechanics lien’s enforceability against the appropriate party while carefully avoiding entanglement with other ownership interests, securing full payment for our client quickly and efficiently, without litigation.
