California Proof Of Service-Civil (Proof Of Service) is a document used to prove that a document has been properly served. It is completed by the process server, who is responsible for delivering the documents. This document must be filed with the court or other recipient in order to confirm that the document has been legally served. California Proof Of Service-Civil (Proof Of Service) is typically used in civil cases, such as divorces, evictions, debt collections, and other types of lawsuits. There are two types of California Proof Of Service-Civil (Proof Of Service): Personal Service and Substituted Service. Personal Service is the delivery of the documents to the recipient in person. Substituted Service is the delivery of the documents to a third party in place of the recipient.
