Process Serving Info

Sometimes people have questions about legal process serving. Here are answers to some of the questions you might have:

What is service of process?

According to United States legal procedure, all parties must be notified if they are facing legal action against them in a court of law. Notification (called service of process) is accomplished through delivery of documents describing the legal action, and those documents include subpoenas, complaints, summonses, writs, replevins and order to show cause among other legal documents.

What does a professional process server do?

A process server is responsible for delivering legal documents to the parties involved in court proceedings. All process servers must adhere to all state regulations governing legal service of process.

Process servers typically locate the individual named on the document, travel to that person to deliver the documents, verify the person's identity before handing over the papers, and then provide their client with a signed proof of service. This proof of service - also called the affidavit of service - details the time, date and location of the service of process, and the subject's name. It is this notarized legal document you can present in court to verify that successful service of process occurred.

Why do I need a process server?

Service of process must be carried out by a professional who understands the state laws and is well-versed on best practices. Any failure to follow legal procedures can result in legal issues for the parties involved in the court case. That very reason is why you should leave service of process to a trusted professional. An experienced and knowledgeable process server will do everything by the book and make it easy to demonstrate that you fairly notified the other parties of impending legal action. Wisconsin state law indicates the process server cannot be one who is involved in the legal action at hand.
