Study guide
A notary public's core job is performing notarial acts correctly, and the exam expects you to know exactly which act a document calls for and why the difference matters. This chapter walks through the most common acts you will perform, the certificate wording that documents them, and the special situations — a signer who cannot write, a signer who cannot travel — that require extra steps.
Acknowledgments vs. Jurats
An acknowledgment and a jurat are the two notarial acts you will perform most often, and they are easy to confuse because both involve a signer, an identification step, and a notary certificate. The difference is what the notary is certifying. In an acknowledgment, the signer may have signed the document before arriving — perhaps at home the night before. The signer personally appears before the notary, the notary identifies the signer through satisfactory evidence, and the signer acknowledges, meaning declares, that the signature on the document is theirs and was made voluntarily. The notary is not asking whether the contents are true; the notary is only confirming who signed and that they did so willingly. A jurat is different: the signer must sign the document in the notary's actual presence, not beforehand, and must also recite a spoken oath or affirmation swearing or affirming that the statements in the document are true. Picture a notary named Priya notarizing a real estate deed for a signer named Marcus. Because a deed typically calls for an acknowledgment, Marcus can arrive with the deed already signed; Priya identifies him and he acknowledges the signature is his. Later that week Priya notarizes an affidavit for a witness named Dana. An affidavit typically calls for a jurat, so Dana must sign the affidavit in front of Priya and swear, aloud, that its contents are true before Priya completes the certificate. Choosing the correct act matters because using the wrong one can misrepresent what actually happened during the notarization. When a document arrives with no certificate attached, however, it is the signer — not the notary — who must choose which notarial act is needed; a non-attorney notary may describe the available acts and their differences, but selecting the act for the signer is widely treated as the unauthorized practice of law, and if the signer cannot decide, they should consult the document's originator, recipient, or an attorney before the notary proceeds.
Oaths and Affirmations
An oath and an affirmation accomplish the same legal purpose: both are solemn, spoken promises that a statement is true or that a person will perform a duty honestly, and both carry the same legal weight and the same penalties for lying under them. The difference is form, not substance. A traditional oath often invokes a higher power, using language such as "do you swear," while an affirmation uses a promise on one's personal honor, such as "do you affirm," with no religious reference. A notary must offer an affirmation as an equally valid alternative for any signer whose personal or religious beliefs make swearing an oath uncomfortable or objectionable; a notary should never insist on one form over the other. The oath or affirmation itself is typically administered with both the notary and the signer standing, right hands raised, and the notary asking a direct question such as, "Do you solemnly swear or affirm that the statements in this document are true?" The signer's clear verbal response — not a nod, not a signature alone — completes the act. This matters most in jurats, where the spoken oath or affirmation is the entire point of the notarization, but oaths and affirmations also stand alone as their own notarial act, such as when a public official swears an oath of office or a witness in a deposition affirms before testifying. A notary named Oscar administering an oath to a new board member, Felicia, would ask her to raise her right hand and repeat the oath language, then complete a certificate stating the oath was administered — no document signature is necessarily involved at all.
Copy Certifications and Typical Exclusions
A copy certification is a notarial act in which the notary compares an original document to a photocopy and certifies that the copy is a true, accurate, and complete reproduction of the original. Unlike an acknowledgment or jurat, no signer identification is required for a copy certification because there is no signature being witnessed — the notary is certifying the copy itself, typically by comparing it page by page against the original the custodian presents. Many states restrict or prohibit notaries from certifying copies of certain documents, most commonly vital records such as birth certificates, death certificates, and marriage certificates, because those records usually have their own official certified-copy process through a government vital records office; using a notary's copy certification on a vital record can create a document that looks official but is not accepted by the agency that issued the original. Public records that are already available from a government office, and documents such as court records, are also commonly excluded from notary copy certification in various states. Before performing a copy certification, it is prudent for a notary to confirm under their own state's rules whether the specific document type may be certified this way at all, since this is one of the more state-variable notarial acts. A notary named Wendell asked to certify a copy of a client's diploma, for instance, would typically confirm the diploma is not on his state's excluded list, compare each page carefully to the original, and complete a certificate stating the copy is true and correct, rather than simply photocopying and stamping without comparison.
Certificate Wording and Completion
The notarial certificate is the paragraph — often on a separate stamped-and-signed page or attached form — that states which notarial act was performed, when, where, and for whom. Complete certificate wording typically includes the state and county where the notarization occurred, the date of the notarization, a description of the act performed (acknowledged, or subscribed and sworn), the signer's name, the notary's signature, and the notary's seal or stamp along with the commission expiration date. Many documents arrive with the correct certificate already printed on them; in that case the notary simply fills in the blanks accurately. When a document has no certificate, or the printed certificate does not match the act the signer actually needs, most states allow or require the notary to attach a separate, properly completed certificate rather than altering the document's own language — and in many states a notary may not attach just any certificate, only one appropriate to what actually occurred. A notary should never notarize a certificate with blank spaces, since blanks invite later alteration or fraud, and should never notarize a document that is undated or incomplete in ways that would misrepresent the transaction. Accuracy in the certificate is not a formality; it is the legal record that a court, title company, or government agency will later rely on to know exactly what the notary witnessed. A notary named Grace who receives a document with an acknowledgment certificate, but whose signer wants to swear to the document's truth as in a jurat, would recognize the mismatch and attach the correct jurat certificate rather than force the wrong form onto the transaction.
Signature by Mark and Subscribing Witnesses
Not every signer can produce a full legal signature, and the notary process accommodates this without lowering its standards for verifying identity and intent. A signer who cannot write, due to illiteracy, disability, or injury, may typically sign with a mark, often an X or a simple symbol, made in the notary's presence. In most states, this mark must be witnessed by one or two additional witnesses who also sign near the mark, and the notary typically notes in the journal that the signature was made by mark and identifies the witnesses. A subscribing witness is a related but distinct concept, used when the actual signer cannot personally appear before the notary at all — for example, someone hospitalized or otherwise physically unable to travel. In many states, a credible subscribing witness may appear before the notary on the signer's behalf, having personally watched the signer sign the document (or having heard the signer acknowledge the signature as their own), and that witness then signs the document themselves and swears to the notary that they witnessed the signing. The notary identifies and notarizes the subscribing witness, not the original absent signer, and the certificate wording reflects that a subscribing witness procedure was used. Because this substitutes for the signer's own personal appearance, most states treat it as a special, tightly bounded procedure rather than a routine option, and a careful notary such as one named Beatriz would confirm her state's specific requirements before agreeing to notarize by subscribing witness.

Exam tips
- If the certificate says "subscribed and sworn," the exam wants you to recognize a jurat, not an acknowledgment.
- Remember: an acknowledgment can be about a document already signed; a jurat always requires signing in the notary's presence.
- Copy certification exclusions (vital records, court records) are commonly tested but vary by state — expect the exam to test the concept, not one state's exact list.
- Never notarize a certificate or document with blank spaces; this is a frequently tested fraud-prevention point.
- Distinguish signature by mark (signer present, cannot write) from subscribing witness (signer absent entirely) — these are different accommodations for different problems.
