Is an e-signature legal in every state?
Short answer: yes, in all 50 states. Here's how the federal and state layers fit together, and the few state-specific nuances worth knowing.
Valid nationwide
Electronic signatures are enforceable in every US state. Two layers make this true: the federal ESIGN Act, which applies to interstate and foreign commerce nationwide, and state-level enactments of UETA. Together they guarantee that a signature or contract can't be denied enforceability just because it's electronic.
The 49 UETA states
The Uniform Electronic Transactions Act has been adopted by 49 states, the District of Columbia, and several US territories. In those jurisdictions, UETA governs electronic records and signatures for transactions within the state, closely mirroring ESIGN's requirements of intent, consent, association, and retention.
New York — the exception that still says yes
New York is the one state that did not adopt UETA. Instead it has its own equivalent, the Electronic Signatures and Records Act (ESRA), which likewise gives electronic signatures the same legal effect as handwritten ones. So even the “exception” confirms e-signatures are valid.
Special rules to watch
Some states add requirements in specific areas — most notably remote online notarization (RON), where rules on identity verification and audio-visual recording vary. Certain consumer notices and documents (wills, some family-law papers) remain outside e-signature laws everywhere. When you generate a document with Certyneo you choose the governing-law state so the wording matches your jurisdiction.

Frequently asked questions
Are there any states where e-signatures aren't valid?
No. All 50 states recognize electronic signatures — 49 via UETA and New York via its own ESRA statute, on top of the federal ESIGN Act.
Does the governing-law state matter?
Yes. While validity is universal, the governing-law clause determines which state's contract law interprets your agreement, so choose the state relevant to your transaction.
What about remote online notarization?
RON is authorized in most states but rules differ on identity proofing and recording. Check the specific requirements of the state where notarization occurs.
