Do Electronic Signatures Need to Be Notarized? A US Guide

Most electronic signatures do not need to be notarized, because the ESIGN Act and state UETA laws make an electronic signature valid on its own; notarization is only required for the specific document types your state law says must be notarized. For everyday business paperwork such as sales contracts, NDAs, offer letters, and most service agreements, an electronic signature is legally binding with no notary involved at all.

TL;DR: The federal ESIGN Act and the state Uniform Electronic Transactions Act (UETA) treat an electronic signature as equal to a pen signature for most contracts, and neither one requires notarization. A narrow set of documents (real estate deeds, some powers of attorney, certain sworn affidavits, and wills) still needs a notary or a witness under state law, and those rules vary by state. Notarization is a separate legal step layered on top of a signature, not a replacement for it, and it can be done in person or through remote online notarization where the state permits it.

One note before the details: this article is general information, not legal advice. Notarization and witnessing requirements vary by state and by document type, so confirm the rules for your specific document before you rely on any of this.

Do electronic signatures need to be notarized?

No, not in most cases. The ESIGN Act and UETA make an electronic signature legally valid for the large majority of contracts and records without any notarization. A notary only enters the picture when a specific state or federal law says that document must be notarized, and that requirement applies whether the document is signed on paper or on a screen.

The key thing to understand is that notarization attaches to the document type, not to the signing method. Nothing about signing electronically triggers a notary requirement. A contract that would not need a notary on paper does not suddenly need one because you signed it electronically. The reverse is also true: a document that state law requires to be notarized still needs a notary even if you sign it with a pen. If you want the background on why an unnotarized electronic signature holds up in the first place, our explainer on whether electronic signatures are legally binding walks through the ESIGN Act and UETA in plain terms, and our guide to using electronic signatures for legal documents covers the practical side.

Does a digital signature need to be notarized?

Generally, no. In everyday usage, people say "digital signature" to mean the same thing as an electronic signature, and the answer does not change: it is valid under ESIGN and UETA without a notary for most agreements. Notarization is only required when the underlying document is one that state law singles out, such as a deed or a sworn affidavit.

There is a narrow technical distinction worth knowing. A "digital signature" in the strict sense refers to a specific cryptographic method (using certificates and encryption) that some platforms use to secure and verify a signature. That underlying technology can make a signature harder to forge and easier to authenticate, but it does not, on its own, satisfy a notarization requirement. Notarization is a legal act performed by a commissioned notary, and no amount of encryption substitutes for it when the law demands a notary.

Can a notary sign an electronic signature?

Yes. A notary can notarize a document that was signed electronically, and the notary applies their own electronic seal and signature to complete the act. This can happen two ways: in-person electronic notarization, where the signer and notary are in the same room but the document and seal are electronic, and remote online notarization, where they meet over audio-video technology.

What the notary is actually doing is notarizing the signing act, not the ink. In practical terms the notary confirms the signer's identity, confirms the signer is willing and not acting under duress, and then certifies those facts with a seal. According to the National Notary Association, a notary checks government-issued identification, screens the signer for willingness and awareness, and does not verify whether the content of the document is correct or lawful. That job is the same whether the signature is wet or electronic.

Do electronic signatures need to be witnessed?

Most do not. The same ESIGN and UETA rules that make an electronic signature valid without a notary also make it valid without a witness for the bulk of contracts. Witness requirements, like notarization requirements, come from the document type and the state, not from the fact that you signed electronically. A standard commercial agreement needs neither.

The documents that commonly do call for a witness are the ones tied to formal execution rules: wills almost always require witnesses (commonly two) under state law, and some powers of attorney and real estate instruments require a witness or a notary or both, depending on the state. The table below shows how the common document types usually break down. Treat it as a starting point, not a final answer, because the specifics shift from state to state.

Wills are the clearest carve-out. Both the ESIGN Act and UETA specifically exclude wills, codicils, and testamentary trusts, along with certain family law matters (divorce, adoption), most court documents, and several notice categories such as utility shutoff notices, insurance benefit cancellations, and product recalls. Much of the Uniform Commercial Code is excluded too, aside from Articles 2 and 2A that cover the sale and lease of goods. For those excluded documents, follow your state's traditional execution rules.

Is it legal to notarize an electronic signature?

Yes, it is legal, and it has been for years. The ESIGN Act and UETA both expressly authorize electronic and remote notarization, and a large majority of US states now permit remote online notarization (RON) in some form. The one firm requirement is that the notary must hold a commission in a state that authorizes the type of notarization being performed.

Remote online notarization, one of the more searched terms in this area, lets a signer and a commissioned electronic notary meet over live audio-video, verify identity, and complete the notarial act without being in the same room. As of early 2025, most US states plus the District of Columbia had enacted permanent RON laws, and additional states allow it by other means. Because the exact rules (accepted ID, recording retention, which acts qualify) differ by jurisdiction, it is worth looking up your state's specific notarial statute and the case law interpreting it before you assume a remotely notarized document will be accepted everywhere you need it, especially across state lines. When a deed or other closing document is involved, our guide to electronic signatures for real estate covers how e-signing, e-recording, and notarization fit together in a property transaction.

Do electronic signatures require a witness?

For most documents, no. A witness is required only when the document type and your state's law call for one, the same standard that governs notarization. Ordinary business contracts, offers, and NDAs are enforceable with an electronic signature alone, no witness and no notary needed.

So the honest summary is this: sign electronically with confidence for the vast majority of your paperwork, and reserve the extra steps (notary, witness, or both) for the specific documents your state flags, such as deeds, some powers of attorney, sworn affidavits, and anything in the wills-and-estates bucket. When you are unsure, the safest move is to confirm the requirement for that exact document in that exact state rather than guessing.

Here is where a signing tool fits, stated plainly: SignSend does not provide notarization. What it does is capture a legally binding electronic signature under the ESIGN Act and UETA, timestamp it, and attach a full audit trail showing who signed and when. If a document also has to be notarized, you handle that with a commissioned notary (in person or through a RON platform) in addition to the e-signature, not instead of it. The two steps stack: the e-signature makes the signature valid, and the notarization satisfies the separate requirement the law imposes on that document.

For the paperwork that needs neither a notary nor a witness, which is most of it, you can upload a PDF and send it for signature on SignSend's free plan, and every completed document comes back with a downloadable audit trail attached. That covers the everyday contracts cleanly, and it leaves you free to route the handful of notarize-or-witness documents to the right process.
