Are there specific guidelines from the DOL or other entities for the timing of processing and forwarding distributions (in this case for a 401(k)/PS plan).

Example 1: The timing between a participant submitting a termination form to their plan administrator, and the plan administrator completing the form and initiating the termination process with the record keeper

Example 2: The timing between the plan administrator receiving the check from the record keeper, and forwarding it on to the terminated participant.

Thanks in advance for your input.
