“Process” is a term referring to judicial paperwork which directs a person or company to do an act according to the rules of the court. A Summons, Subpoena and Order to Show Cause are common examples of process. Process needs to be given to that person or company in a manner specified by the laws of the court in that location, this is called service of process. Service of process must be performed according to the local rules to ensure that the party receives notice of the courts order, which in turn is a prerequisite to the courts enforcement proceeding. If proper service is not made your case will be delayed. This results in increased cost and sometimes loss of tactical advantage. Improper service will also delay the obtainment of evidence and delay court assistance such as injunctions etc.
What is a subpoena?
A subpoena is an order of a court which requires a person to be present at a certain time and place or suffer a penalty (subpoena means, literally, "under penalty"). This is the traditional tool used by lawyers to ensure that witnesses present themselves at a given place, date and time to make themselves available to testify.
