What Is a Special Process Server?
A special process server is a court-appointed or certified individual authorized to deliver legal documents to individuals involved in a court case. This includes serving subpoenas, summonses, complaints, and other critical paperwork.
In Illinois, a special process server differs from a sheriff in that they are typically hired privately and can often offer faster, more flexible service. They play a vital role in the legal process, ensuring documents are served legally and that proof of service is provided for court records.
If you’re wondering, “What does a special process server do in Illinois?“—the answer is simple: they help move your case forward by ensuring the proper parties are notified in a timely, verifiable manner.
