Of course, it’s up to you to read the California notary handbook, the laws mentioned in the notary handbook, the notary public section of the California Code of Regulations, and perhaps the back issues of the newsletters the California Secretary of State publishes.
One of the requirements you will notice is to only use one journal at a time. So if you decide an electronic journal would be legal, you would have to use it for all your notarizations. Some systems require an internet connection. If you’re out in the country, where there is no internet service, or deep inside an office building, where there is internet, but you’re not given the wifi password, you won’t be able to do the notarization.
Also consider how long you have to keep your journal. It appears you must keep them until you are no longer a notary. If you sign up for a service that keeps them online, and decide you don’t like the service, you’re stuck. You’d have to keep paying to keep them stored until you’re no longer an notary, even if you stop using it.
What if the company providing the journal goes out of business. How will you access your journal if a question comes up years after the journal entry was made?
Suppose you remain a notary a long time, say 30 years. If you had been keeping an electronic journal in 1990, Windows 3.1 (the first popular version) hadn’t been released yet. You would have been using DOS. If someone asked you to review a journal entry that had been made in WordPerfect for DOS, do you think you’d be able to?
Do you think you’ll be able to make a certified copy of a journal entry made in 2020 if asked to produce it in 2050?
