I AM A DESIGN PROFESSIONAL ON A COMMERCIAL TENANT SPACE UPFIT PROJECT. THE TENANT HIRED US DIRECTLY TO DESIGN THE UPFIT FOR CONSTRUCTION BY A GC. THE TENANT HAS FAILED TO PAY BALANCE OF FEES (PAST DUE 90+ DAYS BUT LESS THAN 120). WE WISH TO FILE A LIEN AGAINST THE PROPERTY TO PUT PRESSURE ON THE TENANT TO PAY. WHAT MUST WE DO?
