Step 1 — Personal appearance. The signer must personally appear at the time of the notarization. For an in-person act, personal appearance means the person physically appears in a manner that permits the notary and the person to see, hear, communicate with, and provide proof of identification to each other; for an online notarization it means appearance by interactive two-way video and audio conference meeting the Secretary of State's standards (§406.0091(d)). Never notarize for someone who is not present, and never take an acknowledgment by telephone or video unless you hold an online notary commission.
Step 2 — Identify the signer. Use one of the methods in Civil Practice and Remedies Code §121.005: personal knowledge, a current government-issued identification card or other document bearing the person's photograph and signature, or the oath of a credible witness. Section 7 covers the details.
Step 3 — Confirm willingness and awareness. Be satisfied the signer is acting willingly and understands what they are signing. If the signer appears confused, coerced, or under the influence, decline the act.
Step 4 — Confirm the act and the certificate. Identify the act the document requires — acknowledgment, jurat (oath or affirmation), or copy certification — and verify the certificate on the document matches it. A notary who is not an attorney may not choose the type of notarial certificate; only complete the certificate already on the document, and tell the signer to seek the document drafter's direction if it is missing or wrong. Never add a certificate because you prefer it.
Step 5 — Make the record book entry. Complete the entry required by §406.014 at the time of the act.
Step 6 — Complete the certificate and seal it. Sign exactly the name shown on your commission, print or type your name, and affix the seal legibly near your signature without covering text or signatures. The certificate must reflect the truth: the venue where the act occurred, the correct date, and the correct signer name.
Q&A — Signature: must it be readable, or match the one on the commission? Texas does not require the signature itself to be readable, or drawn out in printed letters — a notary signs with their ordinary signature. What the statute fixes is the name: a notary must sign official instruments in the name under which the notary is commissioned (§406.016(b)), so a nickname, initials in place of a commissioned full name, or a married or maiden name the commission does not show is not a proper signing of the office, even if it is the signature you use day to day. Legibility is a practical duty rather than a statutory one: print or type your commissioned name beside every signature — on certificates, loose-leaf pages, and the record book — and keep one signature style for the whole term. The seal independently shows your name, identification number, and the date the commission expires. If your name changes, file the change with the Secretary of State and obtain a seal in the new name before signing it (Section 14). Apostilles turn on the same consistency: to use a Texas-notarized document abroad, the Office of the Texas Secretary of State authenticates the notary's signature and seal, which it checks against its own commission record — a name that does not match the commission, or an impression too faint or cluttered to read, is a common reason a correctly notarized document comes back refused. Apostilles are issued only by the Secretary of State; a notary cannot issue one, and the apostille certifies the signature, seal, and certificate, never the truth of the document's contents. Recordable documents — birth, death, and marriage certificates, court records, and deeds — are authenticated through the agency that holds them, because a notary may not notarize them at all.
Q&A — Missing or wrong venue. The venue line belongs to your notarial certificate, not the signer's legal text, so completing a blank venue — the state and county where the act actually happens — is a notarial function, not the unauthorized practice of law. If a certificate is pre-printed with the wrong county, correct it within your own certificate: one clean strike-through, the correct county printed beside it, initialed and dated in the same pen. Never use correction fluid or erase. If the certificate wording itself is wrong, if the substantive text is blank or altered, or if the closing instructions forbid any marking, request a corrected document instead.
Loose-leaf certificates. Use a separate certificate page only when the document has no certificate, the printed certificate is the wrong type, or there is no room for your seal — and only when the closing agent allows it. Complete the venue, the section that applies (individual or entity), the signer's name exactly as it appears in the signature block, the date, your signature as commissioned, your printed name, your commission expiration, and the seal inside the box, and fill in the "attached to" block identifying the document, signer, date, page count, and your initials. Attach it directly behind the document with a paper clip or binder clip — never a staple, because stapled or punched pages can be rejected by a recording clerk.
Signing for a person who cannot sign (§406.0165). A notary may sign the name of an individual who is physically unable to sign or make a mark if that individual directs it, in the presence of a witness with no legal or equitable interest in the property affected, and the witness is identified the same way an acknowledging person is (Civ. Prac. & Rem. Code §121.005). Beneath the signature, write the statutory statement: "Signature affixed by notary in the presence of (name of witness), a disinterested witness, under Section 406.0165, Government Code."
