Service of process in Pennsylvania
In Pennsylvania, original process must generally be served within the Commonwealth only by the sheriff (Pa.R.C.P. 400(a)); a competent non-party adult may serve only in a limited set of action types (such as actions seeking injunctive, declaratory, or partition relief, or certain cases with diversity). Service must be completed within 30 days of issuing the writ or filing the complaint (Rule 401), though the writ may be reissued or the complaint reinstated to continue its validity.
ProcessServerState provides procedural-information-only summaries of state process-server rules. This is not legal advice. Service of process is a critical step in litigation — if you fail to serve correctly, your case can be dismissed. For complex or contested matters, consult a licensed attorney or a court self-help center. Not affiliated with any court or sheriff's office.
