Are Electronic Signatures Legally Binding in the US?

Yes. In the United States, electronic signatures are legally binding for most business and consumer transactions under the federal Electronic Signatures in Global and National Commerce Act (ESIGN Act) of 2000 and the Uniform Electronic Transactions Act (UETA), which nearly every state has adopted. A signature, contract or record cannot be denied legal effect solely because it is electronic, with some exceptions such as wills and certain notices.

The two laws that make e-signatures valid

ESIGN Act (federal). Enacted in 2000 and codified at 15 U.S.C. § 7001 and following sections, ESIGN provides that in interstate and foreign commerce, a signature, contract or record may not be denied legal effect solely because it is in electronic form. Read the text at Cornell Law School’s LII.

UETA (state). The Uniform Electronic Transactions Act, published by the Uniform Law Commission in 1999, gives electronic records and signatures the same effect as paper at the state level. Nearly all states have adopted it. New York has its own Electronic Signatures and Records Act instead.

What is an electronic signature?

Under ESIGN, an electronic signature is “an electronic sound, symbol, or process, attached to or logically associated with a contract or other record and executed or adopted by a person with the intent to sign the record.” Examples:

• Typing your name.
• Drawing your signature on a screen.
• Clicking an “I agree” button.
• Using a signature in an e-signature platform.

Requirements for a valid electronic signature

Consumer consent under ESIGN

When a law requires information to be provided to a consumer in writing, ESIGN sets additional requirements before electronic delivery can satisfy that rule. These include clear disclosures about the right to receive paper, how to withdraw consent, the hardware and software needed and the consumer’s affirmative consent in a way that shows they can access the electronic records.

Exceptions: documents not covered

ESIGN and UETA do not apply to certain documents, including:

• Wills, codicils and testamentary trusts.
• Adoption, divorce and other family law matters.
• Court orders, notices and official court documents.
• Certain notices, such as termination of utility services, foreclosure or eviction notices for a primary residence, cancellation of health or life insurance and product recall notices.
• Documents required to accompany the transport of hazardous materials.

Some of these areas have their own electronic rules under other laws. See our guide to documents you can’t sign electronically.

State notes

• New York uses its Electronic Signatures and Records Act (ESRA), which also generally recognizes electronic signatures.
• Notarization: many states now allow remote online notarization under specific rules, which is separate from ordinary e-signatures.
• Real estate: deeds and recordings may have county recording requirements, though many counties accept electronic recording.

How to make e-signatures hold up

1. Use an e-signature platform that records an audit trail.
2. Capture clear intent with a signing step and agreement language.
3. Authenticate signers appropriately, such as email verification, access codes or SMS for higher risk.
4. Give signers a copy of the completed document.
5. Store records securely and keep them for the required retention period.

Frequently Asked Questions

Are electronic signatures legally binding in the US?

Yes. The federal ESIGN Act and state laws based on UETA give electronic signatures the same legal effect as handwritten signatures for most transactions. A contract cannot be denied enforceability solely because it was signed electronically, with exceptions for certain documents such as wills.

What makes an electronic signature valid?

An electronic signature is generally valid when the signer intends to sign, the parties agree to do business electronically, the signature is attached to or logically associated with the record and the record can be retained and reproduced. Evidence of who signed strengthens enforceability.

What documents cannot be signed electronically?

Under ESIGN and UETA, exceptions include wills, codicils and testamentary trusts, family law matters such as adoption and divorce, court documents, certain notices like utility shutoffs and foreclosure or eviction notices, insurance cancellations, product recalls and certain hazardous materials documents.

Is a typed name a legal signature?

A typed name can be a valid electronic signature if the person typed it with the intent to sign the record. However, a typed name alone provides limited evidence. E-signature platforms add audit trails and authentication that make it easier to prove who signed.

What is the difference between ESIGN and UETA?

ESIGN is a federal law that applies to interstate and foreign commerce. UETA is a model state law adopted by nearly all states. Both give electronic signatures legal effect, and ESIGN generally defers to state UETA versions that are consistent with it.

Do electronic signatures hold up in court?

Yes, electronic signatures are routinely accepted in US courts. Their strength depends on evidence: an audit trail showing the signer’s identity, the time of signing, the document version and the signing process helps demonstrate validity if a signature is challenged.
