How is proof of service typically established?

Proof of service is typically established via a sworn affidavit or declaration from the process server. This is a formal document in which the process server states under oath that they have successfully delivered or served legal documents to the intended recipient. The affidavit serves as a vital piece of evidence in legal proceedings, as it verifies that the service of process was completed in accordance with the rules and regulations governing such procedures.

The process server's declaration outlines important details, such as the date, time, and location of the service, as well as a description of the individual served. This sworn statement provides a reliable account that can be submitted to the court to demonstrate compliance with service requirements, ensuring that the recipient has been duly notified of the legal action against them.

While other options might involve methods of providing evidence, they do not hold the same weight or formality as a sworn affidavit in the legal context. For example, a written agreement may not involve a formal service process, video recordings could be subject to interpretation and authentication issues, and witness statements alone might lack the necessary legal foundation without being accompanied by the server's oath.
