Are e-signatures legally binding? In the United States and the
European Union, the main statutes say an electronic signature cannot
be denied legal effect just because it is electronic. That is a floor,
not a guarantee: each law has exceptions, and whether a particular
signature holds up still depends on the facts and on other law. This
article describes three frameworks, the federal ESIGN Act, the
state-level Uniform Electronic Transactions Act and the EU's eIDAS
regulation. It is not legal advice, and it does not tell anyone how to
sign a specific document.

## The US ESIGN Act

The Electronic Signatures in Global and National Commerce Act, enacted
June 30, 2000, is codified at [15 U.S.C.
7001](https://www.law.cornell.edu/uscode/text/15/7001). For
transactions in or affecting interstate or foreign commerce, it says a
signature, contract or other record "may not be denied legal effect,
validity, or enforceability solely because it is in electronic form,"
and that a contract may not be denied effect solely because an
electronic signature or record was used to form it.

The statute [defines an electronic
signature](https://www.law.cornell.edu/uscode/text/15/7006) broadly as
"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." Intent to sign is part
of the definition, which is why e-signature platforms record steps
such as clicking to adopt a signature.

ESIGN adds conditions for consumers. Where a law requires information
to be given to a consumer in writing, section 7001(c) allows
electronic delivery only if the consumer has affirmatively consented
after receiving specified disclosures, including the right to withdraw
consent and the hardware and software needed.

It also lists exceptions. [Section
7003](https://www.law.cornell.edu/uscode/text/15/7003) excludes, among
others, laws governing wills, codicils and testamentary trusts;
adoption, divorce and other family law matters; the Uniform Commercial
Code other than a few sections and Articles 2 and 2A; court orders,
notices and official court documents; notices of cancellation of
utility services; notices of default, foreclosure or eviction
involving a primary residence; cancellation of health or life
insurance benefits; and product recall notices.

## UETA at the State Level

The [Uniform Electronic Transactions
Act](https://www.uniformlaws.org/committees/community-home?CommunityKey=2c04b76c-2b7d-4399-977e-d5876ba7e034)
is a model law from the Uniform Law Commission, which publishes its
text and tracks state enactments.

ESIGN and UETA are designed to fit together. Under [15 U.S.C.
7002](https://www.law.cornell.edu/uscode/text/15/7002), a state law
may modify, limit or supersede ESIGN's core rule only if it is an
enactment of UETA as approved by the Uniform Law Commission in 1999,
or if it sets out alternative procedures that are consistent with
ESIGN and do not favor one technology. In practice, that means a
reader checking a US signature question usually needs to look at both
the federal statute and the state's version of UETA.

## eIDAS in the European Union

The EU's framework is [Regulation (EU) No
910/2014](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX:32014R0910),
known as eIDAS, which was amended in 2024 by [Regulation (EU)
2024/1183](https://eur-lex.europa.eu/eli/reg/2024/1183/oj/eng) to
establish the European Digital Identity Framework. Unlike ESIGN, eIDAS
defines three levels of signature.

An electronic signature is data in electronic form attached to or
logically associated with other data and used by the signatory to
sign. An advanced electronic signature must, under Article 26, be
uniquely linked to and capable of identifying the signatory, and be
created with data the signatory can use under their sole control. A
qualified electronic signature is an advanced signature created by a
qualified signature creation device and based on a qualified
certificate.

Article 25 sets the legal effects. Any electronic signature "shall not
be denied legal effect and admissibility as evidence in legal
proceedings solely on the grounds that it is in an electronic form" or
that it is not qualified. A qualified electronic signature "shall have
the equivalent legal effect of a handwritten signature," and one
issued in one member state is recognized in all others. The
regulation's recitals leave it to national law to define the legal
effect of other electronic signatures.

## Common Questions

**Are electronic signatures legally binding in the US?**

ESIGN says a signature or contract may not be denied legal effect
solely because it is electronic, for transactions in or affecting
interstate or foreign commerce. It lists exceptions, and other law
still applies.

**What documents cannot be signed electronically under ESIGN?**

Section 7003 excludes categories including wills and testamentary
trusts, family law matters, court documents and certain consumer
notices. State law may add its own rules.

**What is a qualified electronic signature?**

Under eIDAS, an advanced electronic signature created with a qualified
device and based on a qualified certificate. It has the same legal
effect as a handwritten signature across the EU.

**Is a digital signature the same as an electronic signature?**

Not always. ESIGN defines electronic signatures broadly. "Digital
signature" usually refers to certificate-based cryptographic
signatures, which in the EU map to the advanced and qualified levels.

## What to Watch

The EU's 2024 amendment establishes European Digital Identity Wallets,
which may change how qualified signatures are created. In the US, the
frameworks have been stable for more than two decades, and the open
questions sit in the exceptions and in how courts weigh evidence of
intent.
