5.3 Seal/Stamp Requirements

Montana Notary Seal/Stamp Requirements

Montana's official notarial stamp (the "seal") authenticates that a genuine commissioned notary performed the act. Since October 1, 2013, Montana has required an ink stamp unit with a precise format. The Secretary of State does not supply the stamp — the notary buys it from a vendor and is responsible for keeping it secure.

Stamp Specifications

The rectangular border is mandatory — a stamp whose text is correct but lacks the box border does not comply. Blue or black are the only permitted ink colors; red, green, or embossed-only seals are not acceptable for Montana acts.

Required Text Elements

The stamp must contain all four pieces of statutorily mandated information:

Sample Compliant Stamp

+-------------------------------------------+
|            JOHN Q. NOTARY                 |
|  Notary Public for the State of Montana   |
|            Residing at Helena             |
|   My Commission Expires: 01/15/2030       |
+-------------------------------------------+

The Expiration-Date Format Trap

The Montana commission term is four years from the issuance date, and the expiration date on the stamp must be complete: full month, day, and a four-digit year. The exam tests this directly.

You may not use a fill-in-the-blank stamp; the date must be printed on the stamp itself.

When You Must Replace the Stamp

A worked scenario: a notary commissioned in Billings moves to Missoula mid-term. Crossing out "Billings" by hand is improper — the "Residing at" line is wrong on the stamp, so a new stamp reading "Residing at Missoula" is required, and the old one must be defaced.

Security and Electronic Seals

Keep the stamp under your sole control — never lend it or leave it unattended, and report theft. For RON, the electronic seal must be an exact reproduction of the ink-stamp design applied to the electronic record, with the notary's electronic signature. When the commission ends, defacing the stamp prevents another person from committing fraud in your name.

Affixing the Stamp Correctly

Where and how you place the stamp matters as much as the stamp's design. Impress the stamp near your signature in the certificate area, in a blank space where it will not obscure the certificate text, the signer's signature, or any other writing. A stamp pressed over printed words can render the document unreadable and, on some recordings, lead a county recorder to reject the instrument.

Photographically Reproducible

Montana's stamp must be photographically reproducible so that when the document is microfilmed or scanned by a recorder, the seal still reads clearly. An embossed (raised, inkless) seal is not sufficient on its own in Montana because it does not photocopy reliably — the ink stamp is the official seal.

Lost or Stolen Stamp

Treat the stamp like a signature tool that can be abused. If it is lost or stolen, take prompt steps to prevent misuse, document the circumstances, and report the loss consistent with Secretary of State guidance, just as you would for a journal. A thief who obtains your stamp can fabricate notarizations under your name, so security is a professional duty, not a convenience.

Exam Pitfalls to Memorize

• The border is required — a borderless block of correct text fails.
• Blue or black only — any other color is wrong.
• The expiration date is Month/Day/Four-Digit Year, fully printed (no fill-in).
• Any change to name or residing-at city means a new stamp, not a hand correction.
• The notary, not the state, buys and maintains the stamp, and defaces it when the commission ends. These five facts cover the large majority of stamp questions on the Montana exam.
