The first inkling a notarization is required is the notary verbiage.
There are two notary acts, Acknowledgment and Jurat.
Acknowledgment:
"...On___________before me_________personally appeared___________who proved to me on the basis of satisfactory evidence...."
Jurat:
"Subscribed and sworn to (or affirmed) before me on this___day of___...."
In CA a Will is not required to be notarized, however if you decide you would like it to be notarized, you will need to choose which notary act you wish. I can explain each certificate, however I can not decide for you.
If you have questions, please Remember Me for Notary and contact me.
