Do Electronic Signatures Need to Be Notarized?

"Does this need to be notarized?" is one of the most common questions people have about signing online. The short answer, for most everyday agreements, is no: an electronic signature is already legally binding on its own. Notarization is a separate step that only a specific set of documents actually require.

This article is general information, not legal advice. Requirements vary by state and document type. Check your state's rules — or ask an attorney — for anything high-stakes.

The short answer

For the vast majority of business and personal agreements — contracts, NDAs, proposals, statements of work, consent forms — a plain electronic signature is enough. Under the U.S. ESIGN Act and UETA, an e-signature carries the same legal weight as ink, provided the signer intended to sign and there is a record of the transaction. Notarization is not part of that; it is an extra layer reserved for documents that specifically call for it.

When notarization usually IS required

A notary verifies identity and witnesses signing, which deters fraud on documents where the stakes or the potential for forgery are high. Documents that commonly require notarization include:

• Real estate deeds and many mortgage documents.
• Wills, trusts, and some powers of attorney — rules vary widely by state.
• Certain affidavits and sworn statements filed with courts or agencies.
• Some vehicle title transfers.

If a document is going to be recorded with a government office or filed with a court, treat that as your signal to check whether a notary is needed.

When it is NOT required

Most day-to-day agreements need no notary at all:

• Service contracts, freelance agreements, and SOWs.
• NDAs and confidentiality agreements.
• Employment and onboarding paperwork.
• Sales orders, quotes, and proposals.
• Consent and waiver forms.

For these, a legally binding e-signature with a solid audit trail is the standard, and adding a notary would only slow things down.

Notarization and e-signature are different things

It is easy to conflate them, but they answer different questions:

• An electronic signature captures intent to sign and records who signed, what, and when.
• Notarization adds an independent official who verifies the signer's identity and witnesses the act.

They are not competing — a document can be both e-signed and notarized. This is also different from a "digital signature," the cryptographic technology underneath a good e-signature, which we cover in electronic signature vs digital signature.

What about online notarization?

Many states now allow Remote Online Notarization (RON), where a commissioned notary verifies your identity and witnesses signing over a live video call, then applies an electronic notarial seal. It is a genuine notarization performed remotely — useful when a document truly requires a notary but you cannot meet in person. Availability and rules depend on your state and the notary's commission, so confirm before relying on it.

How e-signatures and notarization work together

If your document does not need a notary — most do not — a legally binding e-signature with a tamper-evident seal and a certificate of completion is the fastest defensible way to get it signed. If it does need one, use RON or an in-person notary for that specific document, and keep everything else on straightforward e-signature. The goal is to add the notary only where it is actually required, not by default.

Frequently asked questions

Do electronic signatures need to be notarized?

Usually not. For most contracts and business documents, a plain electronic signature is legally binding under the ESIGN Act and UETA with no notary involved. Notarization is only needed for specific documents, such as deeds, wills, and certain filings, that require it by law.

Can you notarize an electronically signed document?

Yes. A document can be both electronically signed and notarized. Where a notary is required, many states allow Remote Online Notarization, where the notary verifies identity and witnesses signing over video and applies an electronic seal.

What is the difference between notarization and an e-signature?

An e-signature records the signer intent and a timestamped audit trail of who signed what. Notarization adds an independent official who verifies the signer identity and witnesses the signing. They serve different purposes and can be used together.

How do I know if my document needs a notary?

Check whether it will be recorded with a government office or filed with a court, and check your state rules for that document type. Deeds, wills, and some powers of attorney commonly need one; most everyday contracts do not. When in doubt, ask an attorney.
