5.1 Notary Seal and Stamp Specifications

What the Seal Does

The notary seal (also called the notary stamp) is the official mark that authenticates a notarial act and identifies the commissioned notary who performed it. On most recordable documents the seal carries the same legal weight as the notary's signature: the signature, the seal, and the notarial certificate must all be present and consistent. A certificate with a signature but no seal is invalid for recording or out-of-state use, and a seal with no signature is equally void.

The seal is evidence of authority, not a decoration. It tells a county recorder, a court, or a lender that on the date shown a properly commissioned officer of the state performed the act. Because of that evidentiary power, the seal is a controlled instrument: it belongs to the individual notary, never to an employer, and it may only be used by the notary whose name it bears.

Two Seal Formats

States authorize the seal in one of two physical forms, and many require the inked stamp specifically.

Inked Rubber Stamp

• Produces a visible ink impression directly on the paper.
• Available as self-inking or pre-inked models; ink color is set by state law (commonly black, dark blue, or dark purple).
• Reproduces clearly when the document is photocopied, scanned, or faxed — the reason it is now the dominant required format.

Embosser (Raised Seal)

• Presses a raised, inkless impression into the paper, creating a tactile mark.
• Often does not show on photocopies or scans unless the copier light is angled, so most states no longer accept an embosser as the sole official seal.
• Survives as a secondary security device — many notaries emboss after stamping to deter alteration.

Required Seal Elements

Requirements vary by jurisdiction, but the typical seal must show the following:

Sample Inked Stamp

+---------------------------------+
|         JANE M. SMITH           |
|         Notary Public           |
|       State of California       |
|       Commission # 1234567      |
| My Commission Expires 12/31/29  |
+---------------------------------+

Physical Specifications

Most states cap the seal's size and demand legibility so it reproduces on certified copies.

Placement Rules

A correct seal can still get a document rejected if it is placed wrong. The seal must not cover the signer's signature, the notary's signature, or any printed text on the page. An overlapping or smudged seal can cause a county recorder to refuse the document for recordation, forcing the parties to re-execute and re-notarize — a costly error the exam tests directly. Affix the seal in clear blank space near the certificate, and re-stamp on a loose certificate if there is no clean room.

Security Duties

1. Keep the seal under your exclusive, direct control at all times.
2. Never lend the seal — not to a coworker, supervisor, or even another notary.
3. Store it in a locked location when not in use.
4. Never pre-stamp blank documents or certificates.
5. Report loss or theft immediately to the commissioning authority.
6. Destroy or disable the seal when the commission expires, resigns, or is revoked.

Worked Scenario: The Borrowed Stamp

A bank teller is out sick and her manager grabs her self-inking stamp to notarize a customer's deed. Even though the manager is also a commissioned notary, using another notary's seal is a criminal misuse in nearly every state, and the resulting notarization is fraudulent because the seal names a notary who never appeared. The correct action is for the manager to use her own seal, signature, and journal, or to decline.

Lost or Stolen Seal — Order of Operations

1. Notify the commissioning authority (usually the Secretary of State) at once.
2. File a police report if theft is suspected.
3. Note the loss in your journal with the date and circumstances.
4. Obtain a replacement (often with a new commission number, depending on the state).
5. Watch for unauthorized notarizations performed with the missing seal.

Common trap: Waiting to report "in case it turns up" exposes the notary to liability for any fraud committed with the seal in the interim. Reporting comes first, replacement second.

Expiration, Renewal, and Electronic Seals

The seal is valid only while the commission is. When a commission expires, is resigned, or is revoked, the notary must stop using the seal and, in most states, destroy it or render it unusable so no one can perform a fraudulent act with it. A continuing-to-stamp-after-expiration scenario is a frequent exam item: an expired notary who keeps notarizing is acting without authority, and the acts are void. On renewal the notary often receives a new commission number and expiration date, which means ordering a fresh stamp rather than altering the old one — hand-editing a seal is never permitted.

Many states also authorize an electronic notary seal for electronic and remote online notarization. The electronic seal must contain the same required elements as the physical stamp (name, 'Notary Public,' state, commission number, expiration date) and must be attached to the electronic document so it is tamper-evident — any later change to the document invalidates the seal. The exam expects you to know the electronic seal is a digital equivalent, not a relaxation of the content rules.
