In most cases, yes. If none of the types of Identification listed are available, or it would be excessively difficult for the document signer to obtain them, two additional persons who do have acceptable identification may be present who will swear to the signer's identity. The two individuals have to be over the age of 18, have valid identification ready for inspection and recording in the notaries journal and must swear or affirm, under penalty of perjury, that they personally know the signer. They will also need to be present at the time of witnessing and sign the notary journal.
