California law does not provide the authority for a California Notary Public to perform a remote online notarization. The personal appearance of the document signer is required before the notary public. However, California will accept a notarization performed remotely if done by a notary in a state where remote notarization is authorized.  For example, Remote Online Notarization is authorized in Arizona.  An Arizona notary can remotely notarize a document for a person who is physically located in California and that notarial act will be valid in California.
