How may a subpoena be served?

A subpoena may be served through various methods, which include personal service, mail, or by law enforcement officers. This flexibility allows the party issuing the subpoena to ensure that it reaches the recipient in a timely manner, accommodating different scenarios and circumstances that may arise. Personal service ensures that the individual is directly handed the subpoena, which can confirm receipt, while mailing it can be a more convenient option. Law enforcement can also serve subpoenas to enhance compliance, particularly if there is concern about the recipient evading service.

The other methods of service listed in the alternative choices are more restrictive and do not encompass the broad options available for serving a subpoena. For instance, saying that only law enforcement can serve subpoenas limits the process unnecessarily and overlooks adequate and accepted methods like mail or personal delivery by anyone authorized. Additionally, the option suggesting that a subpoena must be delivered personally is too narrow, as it does not account for mail service, which is an accepted method. Finally, serving via email notification isn't standard practice for subpoenas, as physical delivery methods are typically required to ensure proper legal notice.
