How Notarization Works: A Plain-English Guide

What a notary public actually does, why it matters, and how to prepare for a signing that will hold up in court.

Notarization is a three-step process: identification, willingness, and acknowledgment. A commissioned notary public verifies the signer's identity using a current government-issued photo ID, confirms the signer understands and is willing to sign the document, then witnesses the signature and applies an official seal.

The seal itself does not validate the contents of a document — it certifies that the named person actually signed it on the date stated. That distinction is the bedrock of every property transfer, power of attorney, and sworn affidavit in the United States.

To prepare, bring the unsigned document, valid photo ID, and any witnesses required by the document type. Never sign before the notary arrives.
