Learn how to properly serve defendants in small claims court. Service of process is a crucial step - if done incorrectly, your case can be dismissed. This guide covers all service methods: Certified Mail ($12-15), which is the cheapest option accepted in most states. Process Servers ($50-$150) are professional servers who can handle difficult defendants. Sheriff Service ($30-$90) is an official option with proof of service. Each state has different requirements for acceptable service methods. We cover state-by-state rules, proper timing, and what to do if the defendant avoids service. PettyLawsuit can help you send documents via certified mail with tracking and delivery confirmation. If you need to escalate to a process server or sheriff, we provide guidance on finding services in your area.
