Are electronic signatures legal in the US?
Yes. In almost every case, an electronic signature is as legally binding as ink on paper. Here's exactly how US law treats e-signatures, what makes one enforceable, and the narrow exceptions where paper is still required.
The ESIGN Act: federal recognition of e-signatures
The Electronic Signatures in Global and National Commerce Act (ESIGN), signed into law in 2000, is the federal statute that gives electronic signatures and records the same legal effect as their handwritten, paper counterparts. Under ESIGN, a contract or signature “may not be denied legal effect, validity, or enforceability solely because it is in electronic form.” It applies to interstate and foreign commerce, which covers the vast majority of business agreements.
ESIGN vs UETA — how they work together
The Uniform Electronic Transactions Act (UETA) is a model state law, adopted by 49 states plus D.C., that mirrors ESIGN at the state level. ESIGN sets the federal floor; UETA governs transactions within a state. Where a state has adopted UETA, it generally controls; ESIGN fills the gap in the few places that have not. In practice both point to the same result: an e-signature made with clear intent is enforceable.
What makes an electronic signature enforceable
Four elements matter: (1) intent to sign — the signer took a deliberate action to sign; (2) consent to do business electronically — the parties agreed to use electronic records; (3) association — the signature is logically tied to the record it signs; and (4) record retention — the signed document can be retained and accurately reproduced. A solid audit trail capturing who signed, when, and from where is what turns “signed electronically” into “provably signed.”
The exceptions: when paper is still required
A short list of documents is carved out of ESIGN and UETA and generally still needs a wet signature: wills, codicils, and testamentary trusts; certain family-law documents such as adoption and divorce papers; some court orders and notices; and specific notices like utility shut-offs, foreclosure, eviction, or the cancellation of health or life insurance. For everyday business and commercial contracts, none of these exceptions apply.
Do the rules change by state?
The core answer — e-signatures are valid — is the same in all 50 states, because ESIGN applies nationwide and UETA has near-universal adoption. New York is the one state that did not adopt UETA but has its own equivalent statute (the Electronic Signatures and Records Act). Some states add rules for specific areas like remote online notarization (RON). When you generate a document with Certyneo you choose the governing-law state so the wording matches your jurisdiction.

Frequently asked questions
Is an electronic signature legally binding in the US?
Yes. Under the federal ESIGN Act and state-level UETA, electronic signatures carry the same legal weight as handwritten ones for the vast majority of business and personal contracts.
Will an e-signed contract hold up in court?
Generally yes, provided the four elements are met: intent, consent to electronic transactions, association of the signature with the record, and retention. A strong audit trail is the evidence that makes enforcement straightforward.
What documents still require a handwritten signature?
Mainly wills and testamentary trusts, certain family-law documents, some court notices, and specific consumer notices such as foreclosure or insurance cancellation. Ordinary commercial contracts are not on this list.
Is a typed name a valid electronic signature?
It can be, if it reflects the signer's intent to sign and is properly associated with the document. Dedicated e-signature software strengthens this by capturing intent, identity, and a tamper-evident audit trail.
Do both parties need to sign electronically?
No. A contract can be validly formed even if one party signs on paper and the other electronically, as long as each signature meets the applicable requirements.
