"Service of process" is one of those legal terms that people hear without ever fully understanding what it means or why the legal system cares about it so deeply. Here's the plain-English version.
The Basic Definition
Service of process is the formal legal procedure by which a person (or business) who is being sued is officially notified that a lawsuit has been filed against them and that they must respond. The "process" in "service of process" refers to the court documents — typically a summons and complaint — that initiate the legal proceeding.
Why the Legal System Requires It
The Fourteenth Amendment to the U.S. Constitution guarantees that no person shall be deprived of life, liberty, or property without due process of law. Due process includes, at minimum, the right to notice that legal action is being taken against you and the opportunity to be heard in response.
Service of process is how that constitutional guarantee is fulfilled. Without proper service, a court cannot exercise jurisdiction over a defendant — which means a judgment entered without proper service can be vacated.
What Gets Served
In most civil cases, service of process consists of two documents:
- The summons — a court-issued document ordering the defendant to appear or respond within a specified time
- The complaint or petition — the document that explains what the plaintiff is claiming and what they're asking the court to award
Other documents that require formal service include: subpoenas (ordering someone to testify or produce documents), writs of execution (enforcement documents), temporary restraining orders, and notices of deposition.
Who Serves Process
Missouri law allows service by the county sheriff, by a licensed professional process server, or in some circumstances by any adult non-party to the case. Professional process serving agencies like Faithful Path Investigations provide the documentation standards — GPS timestamps, body camera footage, sworn affidavits — that hold up in court when service is challenged.
What Happens After Service
After service is completed, the process server signs and files a sworn Affidavit of Service (also called a Return of Service) with the court. This document proves that the defendant was properly notified. The defendant then has a court-defined window — typically 30 days in Missouri civil cases — to file a response. Failure to respond within that window can result in a default judgment.

Frequently Asked Questions
- What is the difference between service of process and serving a subpoena?
- Service of process typically refers to delivering documents that initiate a lawsuit — summons and complaint. Subpoena service is a related but distinct process that compels a witness to testify or produce documents. Process servers handle both.
- Does service of process have to happen in person?
- Personal service is the gold standard, but courts authorize alternative methods — substituted service, posting, and publication — when personal service cannot be achieved after good-faith attempts.
