Process service, also known as legal service of process, refers to the formal procedure of delivering legal documents, such as lawsuits, subpoenas, summons, and other court papers, to individuals involved in a legal proceeding. The primary purpose of process service is to notify and inform the recipients (defendants, witnesses, or other parties) of their legal rights, obligations, and the actions being taken against them within the judicial system.

Process service is a fundamental step in ensuring due process and allowing all parties involved in a legal matter to exercise their rights to be heard and participate in the proceedings. It serves as a means to provide legal notice, granting individuals the opportunity to respond, defend themselves, or comply with court orders.

Typically, process service involves a designated individual, known as a process server, delivering the legal documents to the intended recipient. The process server must comply with specific legal requirements and procedures, which vary by jurisdiction. These requirements may include delivering the documents in person, ensuring proper identification of the recipient, and following specific rules regarding timing and method of service.

Process service can be conducted through various methods, including personal service (delivering the documents directly to the individual), substitute service (leaving the documents with another responsible adult at the recipient's home or workplace), or service by mail (sending the documents via certified mail with proof of delivery). The chosen method depends on the laws of the jurisdiction and the circumstances of the case.

The completion of process service is typically verified by the process server through an affidavit or proof of service, which is then filed with the court. This document attests that the legal documents were properly delivered to the recipient according to the applicable laws and regulations.

By ensuring that all parties involved receive proper legal notice, process service helps uphold the principles of fairness, transparency, and procedural justice within the legal system. It plays a critical role in protecting individuals' rights, facilitating legal proceedings, and maintaining the integrity of the judicial process.
