California Proof Of Service By Mail is a type of legal document used when serving legal documents to a party in California. It is typically used when the person to be served cannot be located in person and requires service of process via mail. The California Proof of Service by Mail must be completed in its entirety and then signed in front of a notary public. It is important to note that this document must be signed in the presence of the notary public, not the person being served. There are two different types of California Proof of Service by Mail: 1) General Proof of Service by Mail; and 2) Proof of Service by Mail on a Corporation. The General Proof of Service by Mail is used to serve an individual, while the Proof of Service by Mail on a Corporation is used to serve a legal entity, such as a corporation or LLC. Both forms require the person being served to provide their address, date of service, and the name of the person who served the documents.
