Process server laws in the United States govern how legal documents are delivered, who can serve them, and what procedures must be followed. These laws ensure that defendants receive proper legal notice and that court proceedings are valid.

Because the United States operates under a federal system, process serving laws vary by state. However, general principles apply across most jurisdictions.

Is a License Required in the United States?

There is no nationwide licensing requirement.

Instead:

• Some states require licensing (e.g., California)
• Some require certification or registration (e.g., Texas, Washington)
• Many states do not require licensing at all

Each state sets its own requirements for process servers.

Who Can Serve Process in the United States?

In most states, process may be served by:

• A sheriff or law enforcement officer
• A licensed or registered process server (where required)
• Any adult (18+) who is not a party to the case

The server must be neutral and cannot have an interest in the case.

Federal Rules of Civil Procedure

At the national level, process serving is governed by the Federal Rules of Civil Procedure, particularly Rule 4.

These rules apply in federal courts and influence many state laws.
