Document Notarization: What It Means and How the Process Works

What notarization is, why documents need it, what notaries check, and how to get a document notarized in person or online.

Document notarization is the formal process in which a commissioned notary public verifies a signer's identity, confirms their willingness to sign, witnesses the signature, and applies an official seal and certificate. The notarization doesn't validate the contents of the document — it certifies that the named person actually signed it on the stated date.

Documents need to be notarized when a third party — a court, county recorder, bank, government agency, or foreign jurisdiction — requires assurance that the signature is genuine. Without notarization, these institutions cannot accept the document as evidence of intent.

Common notarized documents include real estate deeds, powers of attorney, advance healthcare directives, affidavits, vehicle title transfers, loan documents, and sworn statements for court filings.

Before notarizing, a notary checks three things: the signer's identity (using current government-issued photo ID), the signer's willingness and awareness (no coercion, no impairment), and the document's notarial certificate (acknowledgment or jurat). The notary does not read or evaluate the document's contents.

Acceptable identification varies by state but typically includes: U.S. driver's license, state ID, passport, military ID, and (in some states) a permanent resident card. Expired IDs are not accepted in most states. A few states permit "credible witness" identification when no ID is available.

Notaries cannot give legal advice, draft documents, certify copies of vital records, notarize for an absent signer (outside licensed RON), or notarize when they have a financial interest in the transaction.

In-person vs remote online notarization: in-person is universally accepted and covers all document types. RON (remote online notarization) is legal in 45+ states, uses video and digital ID verification, and is ideal for time-sensitive contracts and signers in different locations — but a small number of documents (some wills, some real estate) may still require in-person notarization.
