Is it legal in PA to issue a pro se subpoena and hand deliver?

In Pennsylvania, a pro se litigant (someone representing themselves) can issue a subpoena, but it must comply with the state's rules of civil procedure. Generally, subpoenas can be served by hand delivery, but the individual serving the subpoena must ensure that all legal requirements are met, including proper notice and adherence to any relevant local rules. It's advisable to check specific court rules or consult with legal counsel to ensure compliance with all procedural requirements.
