At least 60 days prior to the expiration of each registrant’s registration, the Division of Labor Standards Enforcement shall send a renewal notice to the last known address of the registrant. However, omission of the Division of Labor Standards Enforcement to provide the renewal notice in accordance with this section shall not excuse a registrant from making timely application for renewal of registration, shall not be a defense in any action or proceeding involving failure to renew registration, and shall not subject the Division of Labor Standards Enforcement to any legal liability.
