Notarization is one of those steps people encounter constantly but rarely think about until a document gets rejected without it. Understanding when it's actually required, and what it does, saves a lot of last-minute scrambling.

What Notarization Actually Does

A notary public is a state-commissioned official who verifies the identity of the person signing a document, confirms they're signing willingly and knowingly, and witnesses the signature. The notary then applies a seal or stamp certifying that this happened. What notarization does not do is verify that the contents of the document are true, legal, or enforceable. It verifies the signing, not the substance.

This distinction matters because it explains why notarization exists at all: it's a fraud deterrent. It creates a documented, accountable record that the person who signed a document is who they claimed to be, and that they weren't coerced or impersonated.
