Upon filing an Application for Adjudication the filing party shall serve a copy of the application on all other parties. If the applicant is the injured worker or dependent and is unrepresented, the injured workers' or dependent's application and accompanying documents shall be served by the Workers' Compensation Appeals Board on the parties listed on the application or on the address record in the case file. If a case number has been previously assigned by the Workers' Compensation Appeals Board, that number must be affixed to the application, and service thereof is deemed service of a conformed copy for the purposes of Labor Code Section 5501. If a case number has not been assigned either before or at the time of filing of the application, notification of the case number assigned to the application by the Workers' Compensation Appeals Board shall constitute service of a conformed copy for the purpose of Labor Code section 5501.

Except as provided below, the Workers' Compensation Appeals Board may, in its discretion, designate a party, or lien claimant, or their representative, to make service of notices of the time and place of hearing, orders approving compromise and release, awards based upon stipulations with request for award and any interim or procedural orders. The party, lien claimant, or representative designated to make service shall retain the proof of service and shall not file it unless ordered to do so by the Workers' Compensation Appeals Board.

The Workers' Compensation Appeals Board shall serve all parties and lien claimants of record notice of any final order, decision, or award issued by a workers' compensation judge on a disputed issue after submission.
