ESIGN Act Compliance Guide for Electronic Signatures

What the ESIGN Act says

The Electronic Signatures in Global and National Commerce Act, commonly known as the ESIGN Act, is a federal law passed in 2000. It gives electronic signatures the same legal effect as handwritten signatures for transactions in or affecting interstate or foreign commerce.

ESIGN is intentionally technology-neutral. It does not prescribe a specific technology, certificate, or identity procedure. Instead, it defines an electronic signature as an electronic sound, symbol, or process attached to or logically associated with a contract or record, and executed with the intent to sign.

This broad definition means that clicking an "I agree" button, typing a name, drawing a signature on a screen, or using a signing link can all satisfy ESIGN — provided the parties intend to sign, consent to electronic transactions, and the signed record can be retained and reproduced.

How UETA works alongside ESIGN

UETA, the Uniform Electronic Transactions Act, is a model state law adopted by 49 states. New York has not adopted UETA but has its own Electronic Signatures and Records Act (ESRA) that reaches a similar outcome. Where UETA applies, it gives electronic signatures and records the same legal status as paper and ink.

ESIGN operates at the federal level and pre-empts inconsistent state laws, so a valid electronic signature remains valid even if one party is in a non-UETA state. UETA fills in the details for state-level transactions. Together, ESIGN and UETA create a consistent legal framework for electronic signatures throughout the country.

Both laws agree on the essentials: a signature is valid when there is intent to sign, consent to do business electronically, a clear association between the signature and the record, and an ability to retain the signed document for later reference.

Four requirements for ESIGN compliance

For a transaction to be enforceable under ESIGN and UETA, the following conditions generally must be met:

1. Intent to sign. The signer must intend to execute the document. A clear signature step, such as a typed name or a drawn signature, provides evidence of intent.
2. Consent to electronic records. The parties must agree to conduct the transaction electronically. This is usually obtained before the first signature through a consent checkbox or notice.
3. Association with the record. The signature must be attached to or logically associated with the specific document being signed.
4. Retention and reproduction. The signed record must be capable of retention and accurate reproduction by all parties entitled to it.

What ESIGN does not require

The ESIGN Act does not require advanced cryptography, qualified certificates, government-issued identity verification, or any particular e-signature format. These requirements exist in other jurisdictions, notably under the EU eIDAS regulation, but they are not part of US federal or state electronic signature law.

Courts in the United States evaluate electronic signatures on the surrounding evidence rather than on a formal tier system. A typed name, a click, or a stylus drawing can all be admissible if the platform captures enough evidence to prove who signed, when they signed, and that the document was not altered afterward.

This is why SES is the standard for most US contracts. It is simple, fast, and legally sufficient.

Documents excluded from ESIGN and UETA

ESIGN and UETA do not cover every legal document. The federal law excludes several categories, including:

• wills, codicils, and testamentary trusts
• adoption, divorce, and certain other family-law matters
• court orders, notices, and official court documents
• notices of cancellation or termination of utility services
• notices of default, foreclosure, eviction, or repossession
• product recalls governed by certain consumer protection laws

State-specific exceptions may also apply. For documents in these categories, consult legal counsel before using an electronic signature.

Why SES is enough for US documents

A Simple Electronic Signature satisfies ESIGN and UETA when it is delivered through a platform that captures intent, attribution, and document integrity. Modern e-signature services strengthen SES with audit trails that record timestamps, IP addresses, email confirmations, and device fingerprints.

At JustSignNow, every SES is backed by a tamper-evident audit trail anchored on Bitcoin through OpenTimestamps. This means you can prove when a document was signed and that it has not changed since, using a decentralized timestamp that does not depend on our infrastructure alone.

For US businesses, this level of evidence is typically more than enough to defend the enforceability of NDAs, service agreements, offer letters, supplier orders, invoices, and other routine contracts.
