Where may a subpoena requiring the attendance of a witness at a hearing or trial be served?

A subpoena requiring the attendance of a witness at a hearing or trial can be served at any location within the state of Georgia. This flexibility allows process servers to effectively reach witnesses at various locations, which can include their home, workplace, or any other place where they can be found within the state's jurisdiction. This provision is crucial for ensuring that witnesses can be present at legal proceedings, thereby supporting the judicial process.

The options indicating service limitations, such as only at the courthouse or the witness's home, do not reflect the broader authority granted to process servers under Georgia law. Similarly, limiting service exclusively to federal buildings does not align with the rules governing subpoenas in the state context, which encompasses a wider range of locations for effective witness service.
