Most notary fraud cases involve one of a small number of practices: a false certificate, a certificate completed later, a blank document, or a notary's credibility used for someone else's purpose. Sections 486.660 to 486.670 RSMo prohibit each of them, and Section 578.700 attaches criminal penalties.

Certificate Prohibitions (Section 486.660)

A notary shall not:

#Prohibited actTypical example
1Execute a certificate containing information known or believed to be falseWriting "personally appeared" when the signer was not there; backdating a certificate
2Affix the official signature or seal to a certificate that is incompleteStamping a certificate with the date or signer's name left blank
3Affix the official signature or seal other than at the time of notarization and in the principal's presenceSigning and sealing the certificate the next morning after the signer left
4Provide or send a signed or sealed certificate to another person with the understanding that it will be completed or attached to a document outside the notary's presenceMailing pre-signed, pre-sealed certificates to an out-of-town client

Backdating is a false certificate. The certificate date must be the date of the notarial act (Section 486.740.1(4)). A notary may correct a genuine error only through the Section 486.745.2 procedure (Section 2.5).

Document and Photograph Prohibitions (Section 486.665)

A notary shall not notarize a signature:

  1. on a blank or incomplete document; or
  2. on a document without notarial certificate wording.

And a notary "shall neither certify nor authenticate a photograph."

Handling these in practice:

  • Blank spaces. Ask the signer to complete them, or to strike them out or mark them "N/A" before signing or acknowledging. A nonattorney notary may not tell the signer what to write (Section 486.675).
  • No certificate wording. The signer or the receiving party chooses the act; the notary then attaches the matching certificate in the signer's presence (Section 486.745.1).
  • Photographs. A request to certify that a photo is a "true likeness," or to stamp the back of a passport-style photo, must be refused. A notary may notarize a signature on a separate statement that a person signs, as long as the certificate does not certify or authenticate the photograph.

Deceit and Endorsements (Section 486.670)

  1. A notary shall not perform any notarial act with the intent to deceive or defraud.
  2. A notary shall not use the official notary title or seal to endorse, promote, denounce, or oppose any product, service, contest, candidate for political office, ballot measure for any election, or other offering.

Related rules keep the seal and title for official use only:

  • The seal may not be used for any purpose other than performing notarial acts (Section 486.725.2).
  • An electronic notary's registered electronic seal may be used only for lawful electronic notarizations, and the registered electronic signature may be used for other purposes only if no "notary" title appears in it (Sections 486.940.5-6 and 486.1170.5-6).
  • A notary may not claim powers the chapter does not give, including the power to counsel on immigration (Section 486.680.1; Section 7.3).

Why These Rules Matter: Official Misconduct

Each prohibited act is official misconduct under Section 486.600(14), meaning performance of an act the chapter prohibits. Consequences can stack:

ConsequenceSource
Civil liability for all damages proximately causedSection 486.805.1
Claim against the $10,000 bondSections 486.615.1, 486.805.2
Revocation, or suspension for conduct with a serious unlawful effect on the publicSections 486.810, 486.815
Misdemeanor for knowingly executing a false certificate under 486.660(1): fine up to $500, up to 6 months, or bothSection 578.700.2(3)
Misdemeanor for knowingly performing any other prohibited actSection 578.700.3

Pressure From Others

Requests to break these rules often come from employers, clients, or relatives. Missouri law backs the notary who refuses:

  • Anyone who knowingly solicits, coerces, or influences a notary to commit official misconduct commits a misdemeanor, fine up to $500 (Section 578.700.6).
  • An employer is liable to a notary punished for refusing to violate the law (Section 486.805.4).

Exam Scenarios

  • Pre-stamped stack. A real estate office asks its notary to sign and stamp blank acknowledgment certificates "to save time" for closings next week. This violates Section 486.660(2) and (4).
  • Signer already left. The notary forgot to sign and seal a certificate before the signer left. The notary may not complete it later outside the principal's presence (Section 486.660(3)); the signer must come back for a new notarization.
  • Campaign flyer. A notary who is running a local campaign prints "Endorsed by Mary Hill, Notary Public" with her seal image on flyers for a ballot measure. Section 486.670.2 forbids it.
