A legal process serving is a process in which the notification of actions or court includes delivery of summons, complaints, subpoenas, order to show cause, and writs against a party is made. It’s an essential aspect of Law, and the procedure and requirements may differ from state to state. Once the legal document is delivered to a person who is entitled to receive it, an Affidavit of Service, also called a Proof of Service, is notarized and given to the party who requested the service. In some cases, the legal papers can be faxed or mailed to the process server, but you’ll need to find out if the original papers need to be served.
