State Requirements

State Rules & Requirements

Process serving rules vary significantly by jurisdiction. While federal courts are governed by FRCP Rule 4, each state maintains its own procedural rules covering who may serve process, permissible methods, time limits, and proof of service requirements.

How to use this reference

This reference covers the key variables that differ across state jurisdictions. For each state, the critical questions are: (1) who is authorized to serve process; (2) what methods are permitted; (3) what time limits apply; and (4) what must appear in the proof of service.

State rules are subject to legislative amendment and court rule revision. Always verify current requirements against the applicable state code and court rules before relying on this reference in active litigation.

Key variables

What differs by jurisdiction

01

Who May Serve Process

Some states restrict service to licensed or registered process servers, sheriffs, or constables. Others follow the federal baseline — any person 18 or older who is not a party. California, Florida, Illinois, Nevada, and several other states require registration or licensure.

02

Permissible Methods

All states permit personal service. Most permit substituted service after failed personal service attempts. Service by certified mail is permitted as a primary or alternative method in many states. Electronic service rules vary widely and often require court authorization or defendant consent.

03

Time Limits for Service

Under FRCP Rule 4(m), service in federal court must be completed within 90 days of filing. State deadlines vary: California requires service within 60 days for the statute of limitations to be preserved; New York requires service within 120 days of filing; Texas requires service within the limitations period.

04

Proof of Service Requirements

All jurisdictions require a proof of service documenting the date, time, location, and manner of service. Some states require the proof to be notarized or sworn under penalty of perjury. The required form varies — some states mandate a specific court form; others accept any written affidavit meeting statutory requirements.
