Cost & coverage in California
In California, notary publics typically pay in the ~$20–$100 / yr (notary E&O); ~$500 / yr for bundled business E&O range annually, with common limits of E&O limits you choose (e.g., $25k–$100k); business E&O up to $1M/$2M. What you actually pay depends on California's regulations, your practice setting, prior claims history, and the limits you choose.
Whether an occurrence or claims-made form fits you can also vary by California market availability — this matters most if you change carriers or leave practice, since only occurrence coverage (or added tail coverage) protects you for incidents reported later.
Because premiums and available forms differ carrier-by-carrier, compare quotes on the full guide rather than assuming a single California rate.
