When is a proof of service necessary?

A proof of service is necessary for a Notice Denying Liability because it ensures that the injured worker is formally notified about the denial of their claim. This document serves as legal evidence that the appropriate parties have been informed of the decision, which is essential in workers' compensation cases. The system requires a clear record of such notifications to maintain transparency and allow for the possibility of appeals or other actions by the injured worker.

In contrast, while proof of service may be relevant in other contexts, such as when appealing a claim decision, it is not specifically mandated for all communications with an employee or necessarily required when filing for income benefits. Thus, the need for proof of service is particularly critical for the Notice Denying Liability to ensure that the injured worker's rights are protected and that they have proper knowledge of the status of their claim.
