What is considered prima facie evidence of notification for a subpoena?

The signed return receipt is considered prima facie evidence of notification for a subpoena because it serves as documented proof that the subpoena was formally delivered to the intended recipient. When a process server sends a subpoena through a method that provides a return receipt, the recipient must sign for it upon receipt. This signature confirms that the recipient acknowledges receiving the document, fulfilling the legal requirement to notify the individual about the subpoena.

The significance of the signed return receipt lies in its ability to validate the process server's claim of notification. In legal situations, this documentation can be critical in establishing that proper procedures were followed, and it helps avoid disputes over whether or not the party actually received the subpoena. Other forms of communication, such as a phone call or a delivery confirmation, do not provide the same level of concrete evidence since they do not require acknowledgment from the recipient in a standardized manner. A written statement from the server might support the claim, but it lacks the compelling evidence that an official signed receipt presents.
