Service of process or process serving is a key part of what is known as the “Due Process of Law”. A UPI professional process server will find this person and hand deliver court documents to them so that they are fully informed. Depending on the court case one is involved in, a process server may deliver subpoenas, summons, complaints, order to show cause, or writs. Each state has its own process serving laws and rules that govern civil procedure. The Process Server must follow these laws and regulations legally to deliver these court documents. Usually, a process server must deliver documents to someone by hand. In this legal process of service, court documents are left with management personnel at someone’s place of business or are left with an adult resident of someone’s home.
