A notarial certificate is the written statement a notary public completes to prove that a specific notarial act took place. It records who appeared before the notary, what the notary verified, and when and where the act occurred. The certificate travels with the document itself, giving anyone who later handles it confidence that the signature is genuine and the signer acted voluntarily.
Without that certificate, the notarization effectively doesn’t exist in the eyes of anyone reviewing the document later. Lenders won’t fund a mortgage if the deed of trust lacks a proper certificate. Courts may refuse to accept an affidavit that was never formally sworn. County recorders routinely reject documents when the certificate is missing, incomplete, or unclear. The certificate is the proof that the notarization happened at all.
What Every Notarial Certificate Must Contain
The Revised Uniform Law on Notarial Acts (RULONA) has been adopted in some form by a majority of states. Individual state requirements vary in the details, but the core elements are largely consistent nationwide.
- Venue. The state and county (or equivalent jurisdiction) where the notarization took place, usually printed at the top of the certificate. This establishes that the notary had authority to act in that location.
- Date. The certificate must be dated, and it must be completed at the same time the notarial act is performed, not filled in later.
- Type of act. The wording must make clear what the notary actually did. An acknowledgment uses language like “acknowledged before me,” while a jurat says “subscribed and sworn to before me.”
- Names of the signers. The full name of each person who appeared, matching the name as it appears in the document.
- Notary’s signature. Signed in the same form as the signature on file with the commissioning authority.
- Title of office. The certificate must identify the notary as a “Notary Public” or other authorized notarial officer.
- Commission expiration date. Under RULONA, the certificate must indicate when the notary’s commission expires, if applicable.
- Official seal or stamp. For paper documents, the notary affixes an official stamp or embossed seal. Most states require the stamp to include the notary’s name, the words “Notary Public,” the state of commission, and the commission expiration date. Many states also require a commission number.
RULONA prohibits a notary from signing or stamping an incomplete certificate. Every blank must be filled in before the notary adds a signature and seal.
The Main Types of Notarial Certificates
Not every notarization works the same way. The type of certificate depends on what the notary is being asked to verify, and the document itself (or the party requesting it) usually dictates which form is needed. A notary who is not also an attorney cannot advise the signer on which type to use.
Acknowledgment
An acknowledgment confirms that the signer personally appeared before the notary, was identified, and stated that they signed the document voluntarily. The notary does not need to witness the actual signing. The signer can bring a previously signed document and simply acknowledge that the signature is theirs. Acknowledgments are the most common type and appear on deeds, powers of attorney, contracts, and most real estate documents.
Jurat
A jurat goes a step further. The signer must sign the document in front of the notary and then swear an oath or make an affirmation that the contents are true. The notary administers that oath, making the signer subject to penalties for perjury if they lie. Jurats are standard for affidavits, sworn statements, and depositions. The certificate language typically reads “subscribed and sworn to (or affirmed) before me.”1U.S. Department of State. 7 FAM 850 Taking an Affidavit
The critical distinction: an acknowledgment verifies identity and voluntary signing; a jurat verifies truthfulness under oath.
Certified Copy
A certified copy certificate attests that a photocopy is a true and accurate reproduction of an original document. Notaries face significant restrictions here. In most states, a notary cannot certify a copy of a public record or a vital record such as a birth certificate, death certificate, or marriage certificate. Those must be obtained from the issuing government agency. Notaries can typically certify copies of private documents, such as diplomas, corporate records, or personal letters, where no government custodian holds the original.2American Society of Notaries.

When the Document Has No Notarial Wording: Loose Certificates
Sometimes a document arrives without any notarial wording printed on it, or the existing certificate language doesn’t match the type of act the signer actually needs. In those situations, the notary uses a loose certificate, a separate sheet containing the full notarial wording that gets attached to the document after completion.
Loose certificates must include all the same elements as any other notarial certificate: venue, date, signer name, type of act, notary signature, seal, and commission information. The notary typically staples or otherwise securely attaches the loose certificate so it cannot be separated and reattached to something else. Some states require the notary to note identifying details of the underlying document, such as its title, number of pages, or date, to prevent misuse.
This is where things go wrong more often than people expect. A loose certificate that fails to identify the document it belongs to, or one that’s paper-clipped rather than permanently attached, invites rejection at the county recorder or court clerk.
Remote Online Notarization
As of 2025, at least 44 states and the District of Columbia have enacted laws permitting remote online notarization, where the signer appears before the notary over a live audio-video connection rather than in person.3Congress.gov. H.R.1059 – 118th Congress (2023-2024): SECURE Notarization Act
Remote notarization changes what appears on the certificate. States that authorize it generally require the certificate to include a statement that the act was performed using communication technology. Without that disclosure, the certificate looks like a standard in-person notarization, which can create problems if the document’s validity is later questioned. The notary’s digital seal and electronic signature replace the traditional ink stamp for electronic records, but the certificate must still contain the same identifying information required for any other notarial act.
Errors That Get Documents Rejected
A notarial certificate with mistakes can derail an entire transaction. County recorders, title companies, and courts routinely refuse documents when the certificate is deficient. The most common problems:
- Missing or incorrect venue. Leaving the state and county blank, or listing the wrong jurisdiction, is one of the top reasons documents get bounced at recording offices.
- Incomplete fields. Any blank left unfilled, whether the date, the signer’s name, or the type of act, gives a recorder grounds to reject.
- Illegible or missing seal. A stamp smudged beyond recognition or missing entirely fails the certificate.
- Name mismatches. The signer’s name must appear consistently throughout the document, on the signature line, and in the notarial certificate. Even small discrepancies between the printed name and the signature can cause rejection.
- Wrong certificate type. Using acknowledgment wording when the document calls for a jurat, or vice versa, means the certificate doesn’t match the act that was needed.
When a document is rejected, the usual fix is having the signer appear before a notary again to complete a new certificate. That costs time, money, and sometimes real inconvenience when the signer is hard to reach. In real estate transactions, it can delay closings by days or weeks. For court filings with deadlines, a rejected notarization can mean a missed filing date with real legal consequences.
A notary who discovers an error in a certificate they already completed should not simply cross out and correct it after the fact. Most states require the notary to start fresh with a new certificate, since altering a completed one undermines the integrity the notarization was supposed to guarantee.
Not the Same as a Notary Journal
The certificate and the notary’s journal serve different audiences and should not be confused. The certificate is for the outside world. It attaches to the document and tells anyone who handles it that a legitimate notarization took place. The journal is the notary’s own record, kept for their protection and potentially for regulators or law enforcement.
Many states require notaries to maintain a journal recording every notarial act they perform, including the date, the type of act, the signer’s name, and how the signer’s identity was verified.4American Society of Notaries. Notary Recordbook Requirements If a notarized document is later challenged in court, the journal entry serves as independent evidence of what happened during the notarization, a backup that can be critical if the certificate itself is disputed or the document has been altered.
