California Notarial Certificate – Proof of Execution by Subscribing Witness

The California notarial certificate (proof of execution by subscribing witness) is used when a principal individual has signed a document but is unable to acknowledge (confirm) the signature before a notary public. Another individual, referred to as the “subscribing witness,” may visit the notary and acknowledge the signature on the principal’s behalf. The subscribing witness must prove their identity to the notary by showing a valid form of identification. The subscribing witness must also present an oath or affirmation from a credible witness who knows both the subscribing witness and the notary public.

Laws – § 1195



A notary public or other officer completing this certificate verifies only the identity of the individual who signed the document to which this certificate is attached, and not the truthfulness, accuracy, or validity of that document.
