Document Authentication

Notary

A licensed public official authorized to certify document authenticity, administer oaths, witness signatures, and prevent fraud in legal documents.

While straightforward in theory, many businesses fail to actively track obligations tied to this concept - often resulting in missed deadlines, unintended renewals, penalties, or loss of contractual rights.

What is a Notary?

A notary public is a state-licensed, impartial official authorized to perform a limited set of official acts: administer oaths and affirmations, certify the authenticity of signatures, verify the identity of parties signing documents, and certify copies of public documents. The primary role of a notary is to prevent fraud by confirming that the person signing a document is who they claim to be and that they are signing voluntarily and with understanding of the document.

Notarization is a form of authentication that adds a layer of credibility to documents that will be used in business, legal, or government contexts. When a document is notarized, the notary's signature, seal, and official stamp indicate that the notary personally verified the signer's identity and observed their signature. This is particularly important for documents that transfer property (deeds, mortgages), create legal powers (powers of attorney), or make sworn statements (affidavits) that could be relied upon in court or government proceedings.

While notarization is a standard fraud-prevention mechanism, it is important to understand what a notary cannot do. Notaries cannot provide legal advice, draft documents, or verify that a document is correct or legal. They only verify identity and that the signature is voluntary. A notarized document does not mean the document is legal, valid, or enforceable - only that the signature was made by the person identified and in the notary's presence.

In practice, many teams rely on a contract expiry tracking system to stay on top of dates and obligations tied to clauses like this.

Key Elements
Identity Verification
Before notarizing, the notary must verify the signer's identity using government-issued photo identification - driver's license, passport, or state ID. The notary must confirm they recognize the person or verify the ID. Without proper identification, the notary should refuse to proceed.
Witnessing the Signature
The notary must personally observe the signer sign the document in their presence. The signer cannot sign before the notary meeting. This ensures the signature is genuine and voluntary, and that the signer understands what they are signing.
Oaths and Affirmations
A notary can administer oaths (sworn statements) and affirmations (non-religious sworn statements) certifying that the information in a document is true and correct. The oath language is important - the notary must ask the signer if they swear (or affirm) that the statements are true before signing.
Notarial Certificate
The notary must attach a notarial certificate to the document - a statement signed and sealed by the notary certifying that they verified identity, witnessed the signature, and (if applicable) administered an oath. The certificate should include the date, the notary's name and serial number, the signer's name, and the method of ID used.
Notary Cannot Provide Legal Advice
Notaries are not lawyers and cannot advise on the meaning, legality, or enforceability of documents. They cannot interpret contracts, explain legal consequences, or recommend changes. If a signer has legal questions, they must consult a lawyer.
Real-World Example
Scenario

MariaCorp is selling a commercial property to BuilderInc. The deed transferring the property must be notarized under state law. Maria goes to a notary with the unsigned deed. The notary asks to see her driver's license, verifies her identity, confirms she understands she is signing a property deed, and watches her sign. The notary administers an oath certifying that Maria is the property owner and has authority to sign. The notary stamps the deed with her official seal and signature, certifying that Maria signed voluntarily and in the notary's presence.

This is proper notarization. The deed is now notarized, which satisfies the legal requirement for property transfers in most states. The notarization does not guarantee the deed is valid or enforceable - it only certifies that Maria signed it in the notary's presence after identity verification. If the property had a lien that Maria did not disclose, or if Maria did not actually own the property, the deed could still be invalid despite notarization. But the notarization prevents fraud by confirming Maria signed it herself.

This is why many businesses adopt automated deadline tracking to ensure no critical dates are missed before they pass.

Sample Clause Language
Notarial Certificate (affidavit)
STATE OF [STATE] COUNTY OF [COUNTY] Before me, [Notary Name], a Notary Public, duly commissioned and qualified in and for said County and State, personally appeared [Signer Name], known to me to be the person whose name is signed to the above instrument, and being duly sworn by me, declared that the facts and statements contained in the foregoing instrument are true and correct. IN WITNESS WHEREOF, I have hereunto set my hand and affixed my official seal on this _____ day of _____________, 20____. _____________________________ [Notary Signature] [Notary Printed Name] Notary Public Statewide Notary No. [Number] My Commission Expires: [Date]
Watch Out For
Assuming notarization means the document is legal or valid
Notarization only verifies identity and signature. It does not mean the document is legal, correct, or enforceable. A notarized document can still be void if it violates public policy, lacks consideration, or was procured by fraud. Always have a lawyer review important documents before notarizing.
Using a notary for legal advice or document preparation
Notaries are not lawyers and cannot interpret documents, provide legal advice, or prepare legal instruments. Asking a notary to explain a contract or help you decide whether to sign is improper. Consult a lawyer if you have legal questions.
Signing documents remotely or outside the notary's presence
Many states now allow remote notarization via video, but the signer must still be in the notary's physical or virtual presence and must sign during the notarization. Signing before meeting with the notary and then asking them to backdate the notarization is improper and voids the notarization.
Don't let notary deadlines catch you off guard

Key dates tied to notarys - renewal windows, expiry cutoffs, notice periods - can easily slip through the cracks when tracked manually. Missing them triggers automatic extensions, penalties, or lost rights. ExpiryEdge tracks every critical deadline and sends automated reminders before they're due - so nothing slips.

Instead of relying on spreadsheets or manual follow-ups, a centralized renewal reminder system ensures every deadline is visible, tracked, and actioned automatically.

How to Use This in Your Favor
Bring proper identification when getting documents notarized
The notary will ask for government-issued photo ID. Bring a driver's license, passport, or state ID. Without proper ID, the notary must refuse to proceed. Have alternative ID available if your primary ID is expired.
Understand that notarization is just one part of document authentication
Notarization prevents fraud by verifying identity and signature. For important transactions, it should be combined with legal review, title insurance (for property), and other protections. Do not rely on notarization alone to verify that a document is valid or that the other party has authority.

Frequently Asked Questions

Yes. A notary can refuse to notarize if: the signer cannot provide proper ID, the signer is not present in the notary's physical presence, the signer appears to be under duress, the document appears to be illegal or fraudulent, or the notary has a personal interest in the document. A notary who suspects fraud or illegality should refuse.

Notarization involves witnessing a signature and verifying identity. Certification involves a notary copying a public document and certifying that the copy is true and accurate. Different procedures apply, and not all notaries are authorized to certify - only those holding a certification commission.

Many states now allow remote notarization by video, where the notary and signer are not physically present together. The signer must still provide ID verified in real-time, sign while observed by the notary, and the notary must follow all state requirements. Check your state's laws - some states do not yet allow remote notarization.
