Proof of service is mandatory with what type of notice?

• A. Notice of Hearing
• B. Notice of Claim
• C. Notice of Payment
• D. Denial

Answer: (D)

When someone’s claim is denied, the notice must come with proof that the other party actually received it. This is about ensuring due process: the claimant needs to know the decision and the opportunity to respond or appeal within the required timeframes. A denial directly affects the claimant’s rights and the course of the claim, so documenting that the denial was served is essential.

Proof of service isn’t as tightly emphasized for every type of notice, but for a denial it’s specifically required to confirm that the claimant has been properly notified of the adverse decision and the next steps. This helps prevent disputes about whether the claimant received the denial and whether any appeal or hearing rights have been preserved.

In practice, the denial is typically served to the employee, and the file will include a declaration or other proof showing when, how, and to whom service was made.
