The fee schedule is a ceiling, not a menu
Government Code § 8211 opens by stating that fees for the listed services shall not exceed the amounts prescribed, which makes every figure a maximum, not a fixed or minimum charge. The core numbers: fifteen dollars ($15) for each signature taken on an acknowledgment or proof, a sum that already includes the seal and the writing of the certificate, so three signatures allow at most $45; fifteen dollars ($15) for administering an oath or affirmation to one person and executing the jurat, including the seal; and, for a deposition, thirty dollars ($30) for all services rendered, plus seven dollars ($7) for administering the oath to the witness and seven dollars ($7) for the certificate, a maximum of $44 in total. Certifying a copy of a power of attorney under Probate Code § 4307 is capped at $15. Two acts are free by law: no fee may be charged to notarize signatures on vote by mail ballot identification envelopes or other voting materials, and, in accordance with § 6107, no fee may be charged to a United States military veteran for notarization of an application or claim for a pension, allotment, allowance, compensation, insurance or other veteran's benefit. Charging more than the prescribed fees is itself a ground for discipline under § 8214.1(h), and sits in the $750 civil-penalty tier of § 8214.15(b).
Conflicts, discipline and criminal liability
A notary with a direct financial or beneficial interest in a transaction shall not perform any notarial act in connection with it, under Government Code § 8224: for real property that means being named individually as grantor, grantee, mortgagor, mortgagee, trustor, trustee, beneficiary, vendor, vendee, lessor or lessee, while acting merely as an agent, employee, insurer, attorney, escrow or lender for an interested person does not count. Section 8224.1 closes the loop: a notary may not take the acknowledgment or proof of instruments the notary executed, nor have their own depositions or affidavits taken by themselves. The discipline catalogue in § 8214.1 runs from a substantial and material misstatement in the application, through conviction of a felony or an offense involving moral turpitude (a nolo contendere plea counts as a conviction), to overcharging, failing to complete the acknowledgment when signing and sealing, executing a certificate known to contain a false statement, failing to secure the journal or seal, and willfully refusing a peace officer access to the journal. Before most action the notary has a right to a hearing under § 8214.3, conducted under the Administrative Procedure Act. The money side is tiered by § 8214.15: up to $1,500 for a known-false certificate or a willful failure of duty, and up to $750 for overcharging, incomplete acknowledgments, omitted oaths or a negligent failure of duty, with denying journal access and skipping a required thumbprint each drawing up to $2,500 under §§ 8214.21 and 8214.23. Criminal law sits on top: destroying or concealing notarial records is a misdemeanor under § 8221, willful journal or seal failures are misdemeanors under § 8228.1, impersonating a notary is a misdemeanor under § 8227.1 and becomes a felony under § 8227.3 when it touches documents affecting title to a single-family residence of not more than four units, and a notary who knowingly and willfully, with intent to defraud, issues a false acknowledgment on a deed of trust on such a residence is guilty of a felony under § 8214.2. Injured parties can also sue: § 8214 makes the notary and the bond sureties liable in a civil action for all the damages sustained.
