eSignature legality summary
The United States follows a two-tier model. ESIGN governs transactions affecting interstate or foreign commerce, while UETA (or an equivalent) governs at the state level. Both apply only to records and signatures tied to a “transaction” — broadly, business, commercial, or (under UETA) governmental affairs between two or more parties. An electronic signature cannot be denied legal effect, validity, or enforceability solely because it is electronic. If enforceability is challenged, the party relying on the signature generally must show that the signer intended to sign, that the signature is attributable to that signer, that it is associated with the record, that the signer could retain a copy, and that the record’s integrity has been preserved.
Types of permitted electronic signature
ESIGN and UETA define an electronic signature broadly as any electronic sound, symbol, or process attached to or logically associated with a record and adopted by a person with the intent to sign. No specific technology, certificate, or hardware is mandated — a typed name, a drawn signature, or a click-to-sign capture can each qualify when intent and attribution are evident. A robust audit trail (timestamps, identity verification, IP, and a tamper-evident sealed record) strengthens enforceability.
Documents that may be signed electronically
Commonly signed electronically: HR and employment paperwork, NDAs, software licenses, education and technology-sector agreements, life-sciences contracts, and most consumer transactions (subject to certain post-default notice rules and state-specific carve-outs, such as items excluded under California’s UETA).
Use with caution / not typically appropriate
Some categories remain electronically permissible but warrant a careful assessment or a higher-assurance method — for example corporate resolutions, procurement, bills of lading, healthcare records, FDA clinical-trial records, banking and wire-transfer agreements, lending, real estate, chattel paper, and insurance. Others are excluded outright. Where notarization, recording, or regulated formalities apply, confirm the requirements before signing electronically.
