ESIGN Act vs UETA: US electronic signature law, explained

The Signet team··6 min read

In the United States, two laws give electronic signatures their legal force: the federal ESIGN Act and the state-level UETA. They work hand in hand, and together they make electronic signatures as valid as ink on paper for most transactions.

If you sign contracts with US clients or across state lines, it helps to understand how the two relate.

What each law is

The ESIGN Act (the Electronic Signatures in Global and National Commerce Act, 2000) is a federal law. It establishes that a signature, contract or record cannot be denied legal effect simply because it is electronic. It applies across interstate and international commerce.

The UETA (the Uniform Electronic Transactions Act, 1999) is a model law adopted, with minor variations, by almost every state. It provides the same core principle at state level, governing transactions within each state.

How they overlap and where they differ

The two are deliberately consistent. Both say electronic signatures and records are valid, and both rest on the parties agreeing to do business electronically.

The main differences are about scope:

  • Federal versus state. ESIGN is national and covers interstate commerce. UETA operates within each adopting state.
  • Interaction. Where a state has adopted UETA in a way consistent with ESIGN, the state law generally governs. ESIGN fills the gaps and provides a national floor.
  • Consumer consent. ESIGN sets out specific consumer disclosure and consent requirements when records are provided to consumers electronically.
  • Exclusions. Both carve out certain documents, such as wills, and some notices like foreclosure or utility cut-offs, that may still require paper.

For everyday business contracts, ESIGN and UETA point in the same direction: an electronic signature, properly captured, is legally binding.

The four practical requirements

Whichever law applies, valid electronic signatures generally come down to four things:

  • Intent to sign. The signer must intend to sign, just as with a paper signature.
  • Consent to do business electronically. The parties must agree to use electronic records, and for consumers this consent has specific conditions.
  • Attribution. The signature must be attributable to the person, supported by evidence such as an audit trail showing how it was made.
  • Retention. The record must be capable of being retained and accurately reproduced by everyone entitled to it.

Meet these four, and your electronic signature stands on solid ground. Miss the record-keeping in particular, and even a valid signature becomes hard to defend.

What it means for signing across states

The good news is that you do not need a different process for every state. Because ESIGN provides a national baseline and UETA is broadly uniform, a signing workflow that captures intent, consent, attribution and a durable record will work across the country.

This is where the evidence behind the signature earns its keep. Every document completed with Signet carries a tamper-evident audit trail, a certificate of completion, and public, independent verification, on every plan. Signet is aligned with the ESIGN Act and UETA, encrypted at rest, and never uses your documents to train AI. You can review the detail on our security page, and check any completed document with our public verification tool.

This article is general information, not legal advice. US requirements can vary by state and document type, so take advice for high-value or unusual transactions.

Is a signed PDF legally binding? (What actually counts)

A signed PDF can be legally binding — but a typed name or pasted signature image often isn't the part that holds up. What matters is provable evidence: who signed, that they meant to, and that nothing changed afterwards.
