Electronic Signature Law in the USA: ESIGN & UETA

Are electronic signatures legal in the US?

Yes. Electronic signatures are legally binding across the United States under two laws working in tandem: the federal ESIGN Act and the state-level UETA. UETA has been adopted by 49 states (Uniform Law Commission), with the ESIGN Act covering the rest nationwide.

That combination means a signed contract holds up whether the transaction crosses state lines or stays local. The core promise is simple. A record cannot be rejected just because it lives in electronic form. For most everyday agreements, a click or typed name carries the same weight as ink on paper.

So which law governs your deal? Usually both touch it. The next sections break down each one, starting with the federal layer. For a deeper history, see our plain-English guide to the ESIGN Act.

What does the ESIGN Act say?

The ESIGN Act, formally the Electronic Signatures in Global and National Commerce Act, was signed June 30, 2000 and took effect October 1, 2000. It is codified at 15 U.S.C. 7001 et seq. and sets the federal floor for electronic records in interstate commerce.

Its general rule sits in Section 7001(a). A signature, contract, or record "may not be denied legal effect, validity, or enforceability solely because it is in electronic form." That single sentence does the heavy lifting. It does not force anyone to sign electronically. It simply removes the electronic format as a reason to throw out an otherwise valid agreement.

Because ESIGN is federal, it reaches every state. But Congress built in room for state law to lead, which is where UETA enters the picture.

What is UETA and which states adopted it?

UETA, the Uniform Electronic Transactions Act, was promulgated in 1999 by the Uniform Law Commission. It gives states a consistent, technology-neutral framework for electronic signatures and records. It has been adopted by 49 states, plus the District of Columbia, Puerto Rico, and the U.S. Virgin Islands (Uniform Law Commission).

New York is the only state that has not adopted UETA. Instead, it relies on its own Electronic Signatures and Records Act, known as ESRA, which reaches the same practical outcome through different statutory language. So even the holdout recognizes electronic signatures.

The 49th adoption arrived recently. Illinois became the 49th state to adopt UETA on June 25, 2021 (Uniform Law Commission), retiring its older standalone statute. For the practical view of which framework controls a given deal, our reference page on ESIGN and UETA walks through the mechanics.

How do ESIGN and UETA work together?

ESIGN and UETA cover the same ground from two directions, and federal law decides who yields. ESIGN preempts inconsistent state law, but 15 U.S.C. 7002 lets a state escape that preemption if it has adopted the 1999 version of UETA or an equivalent technology-neutral law.

In plain terms: if a state runs on UETA, that state's version governs the transaction. If a state went its own way with rules that clash with ESIGN, the federal act steps in. New York's ESRA functions as the recognized equivalent, so the gap closes. The two laws rarely fight in practice. The table below maps the split.

This structure is the quiet strength of U.S. e-signature law. Most countries pass one statute and stop. The U.S. pairs a federal backstop with state-led rules, so a contract stays enforceable whether it is local or national.

What makes an electronic signature legally valid?

There is no single statutory checklist for a valid e-signature. Courts and practitioners read a set of generally recognized requirements out of the ESIGN Act and UETA (15 U.S.C. 7001). Meeting all four is what makes an electronic signature hold up if challenged.

Intent to sign

The signer must show a clear intent to sign. Typing a name, drawing a mark, or clicking a confirm button all qualify, as long as the action is deliberate.

Consent to do business electronically

Each party must agree, openly or by conduct, to transact electronically. Signing tools usually capture this with an explicit checkbox before the document opens.

Association with the record

The signature must be tied to the specific record it approves. The connection between signer and document has to be clear, not floating loose.

Record retention

The system must keep an accurate record that can be reproduced later. A downloadable, fully executed copy that mirrors what was agreed satisfies this point. Miss any one of the four and enforceability gets shaky.

Which documents cannot be signed electronically?

Some documents fall outside ESIGN entirely. Section 7003 carves out categories where the stakes or formalities call for paper, and an electronic version may not carry legal effect. Knowing the list keeps you from signing something that will not stand.

The excluded categories include:

• Wills, codicils, and testamentary trusts
• Adoption, divorce, and other family law matters
• The Uniform Commercial Code, except sections 1-107, 1-206, and Articles 2 and 2A
• Court orders, notices, and other official court documents
• Utility service cancellation notices
• Default, foreclosure, repossession, or eviction notices on a primary residence
• Health and life insurance cancellation notices
• Product recall and safety notices

Note the UCC line carefully. ESIGN does not exclude the entire code, only parts of it, and Articles 2 and 2A on sales and leases stay inside the law's reach. Everything outside this list is generally fair game. For the broader rules on what counts, read our overview of electronic signature legality and how it differs from a wet-ink signature. When the document type is clear, you can send it for signature the same day.
