The serving process is a job that is surrounded by many misconceptions. Usually taken up by private investigator firms, process serving is a function that operates privately, independent of the courts, to deliver court materials and legal documents by an impartial third party.
Common uses are to deliver materials and contracts to unwanted parties or to summon defendants directly with subpoenas.
Processes are court documents or legal documents that can range from subpoenas to appeals. A process server is used to conduct a judicial review of whether a document has been received from either party in the case.

As a quick example, imagine that you are a tenant who sues your landlord in court for failing to repair some items in your home under rent. The landlord refuses to answer your phone and you have decided to take it to court to pay the rent or force the landlord to repair it.
Your attorney will use a litigation server to track your landlord and send a subpoena, making them legally required to appear in court on the specified date. However, the test server will not work for you and your attorney.
The fact that they are the third component is very important to run the process server. People have the misconception that a trial server works for the plaintiffs, but a certified trial server must have sworn to say that it is completely impartial in providing documents.
