It depends on the state, but typically the county sheriff or constable, a registered or licensed private process server, or in many states any adult who is not a party to the case. Some states also allow service by certified mail through the court clerk.

Yes. Service of process fees are generally recoverable court costs. If you win, the judgment can include the filing fee and the cost of service. Keep the process server invoice and file the proof (affidavit) of service with the court.
