JURAT

•  A verification (Jurat) contains the words "subscribed and sworn (or affirmed) before me...." When this language is used, you must verbally administer an oath to the signer prior to the execution of the document.
• An oath can be administered as follows: "Do you swear that the statements in this document are true?" When a person is unable to "swear" due to personal or religious beliefs, the following oath may be used: "Do you affirm that the statements contained in this document are true?"
• To notarize the Jurat without administering the oath can affect the validity of the document.

In Addition, a lawful notary in the state of California must have these five elements.  

If any of these elements are missing the notary cannot proceed:

• Requires Personal Appearance  - This essential element of the notarial act is personal, face-to-face communication between the document signer and the notary. 
• Document Must Be Complete - Any document needing to be notarized, must be complete.  All pages or attachments, must be present.  Any dates, need to be dated for that day or earlier, but never later than the notarization date.  
• Notary Must Identify and Screen the Signer - The notary must be able to assess the signer's awareness and willingness that they are signing of free will, to help ensure that neither coercion nor fraud are present.   As well, a notary’s is to determine beyond all reasonable doubt, the identity of the signer.  This is done by providing Satisfactory Evidence.  The signer may produce a state-approved Identification Document, or have witnesses present, and have them provide an oath of one or two credible witnesses.  
•  Record the Notarization in a Journal - Then journal is the paper trail, which is sometimes needed to be used in a court of law.
