ESIGN Act

What the ESIGN Act does

Before 2000, electronic signatures existed in a legal grey zone in the US. The ESIGN Act resolved this by establishing three core principles:

1. Legal recognition — a contract cannot be denied legal effect or enforceability solely because it's in electronic form or signed electronically.
2. Intent requirement — the signer must clearly intend to sign electronically (not accidentally).
3. Consumer protection — consumers must affirmatively consent to receiving records electronically and can withdraw consent.

What ESIGN covers

• Business contracts (B2B and B2C)
• Sales agreements and purchase orders
• Employment offer letters and onboarding documents
• Loan and financial agreements
• Insurance policies and claims
• Real estate contracts (but not deeds in most states)
• Healthcare forms (non-HIPAA-regulated)

What ESIGN does NOT cover

Certain high-risk documents are excluded and still require traditional signatures or notarization:

• Wills, codicils, and testamentary trusts
• Family law matters (adoption, divorce)
• Court orders and official court documents
• Product recall notices
• Utility service cancellations
• Health insurance cancellations

Federal vs state law: UETA

The ESIGN Act is federal law, but most states also adopted the Uniform Electronic Transactions Act (UETA) which covers intrastate transactions. 49 states plus DC have adopted UETA — only New York has a different but similar state statute. In practice, both laws produce essentially the same result: e-signatures are legally valid for business transactions.

Practical compliance tips

• Show clear intent — have signers click a button labeled "I agree to sign", not just navigate away
• Capture audit trail — IP, timestamp, email verification for attribution
• Tamper evidence — use tools that cryptographically seal the document after signing
• Provide copies — email the signed document to all parties
• Allow consumer opt-out — B2C contracts must allow paper alternatives if requested
