The Lien Affidavit must be served on the Property Owner within no later than the 5th day after it has been filed with the County Clerk’s Office. You are not required to serve the filed copy. If you were not hired by the Property Owner, then you must also serve the Lien Affidavit on the Original Contractor. The Lien may be served in person, by any traceable means of service (e.g., FedEx) or by certified mail return receipt requested.
