Is an electronic signature legal in the U.S.?
Short answer: yes, for almost every contract you will ever sign. Here is what the ESIGN Act and UETA actually require, where the exceptions are, and how a platform like Kligrafia builds evidence that holds up if it is ever challenged.
Short answer
Yes. Under the federal ESIGN Act and UETA (adopted by 49 states), an electronic signature has the same legal effect as a handwritten one for most contracts, as long as the signer intended to sign and agreed to transact electronically. A short list of document types is excluded — wills, certain family-law filings, and a handful of consumer-protection notices among them. Kligrafia builds an evidence report designed to meet the FRE 901 authentication standard from the first signature.
What the ESIGN Act says
The Electronic Signatures in Global and National Commerce Act (15 U.S.C. §7001 et seq.), passed in 2000, is federal law: a signature, contract, or record may not be denied legal effect solely because it is in electronic form. That single rule is what makes e-signatures usable for interstate commerce across the entire country.
It does not require any particular technology or vendor. What it requires is that the signer intended to sign and consented to conduct that transaction electronically — the same requirements Kligrafia’s signing flow is built around.
What UETA adds
The Uniform Electronic Transactions Act is the state-law counterpart to the ESIGN Act, adopted — with minor local variations — by 49 states. It fills in the details that federal law leaves to the states, like how electronic records satisfy a state requirement that something be “in writing.”
New York is the one state that did not adopt UETA; it uses its own analogous law, the Electronic Signatures and Records Act (ESRA), with a broadly equivalent effect. Between the ESIGN Act and UETA/ESRA, electronic signatures are covered in every U.S. state.
What makes it valid
Four things a valid electronic signature needs.
- Intent to sign: the signer must have taken an action that shows they meant to sign, not an accident or a default checkbox.
- Consent to do business electronically: the signer agreed to conduct this particular transaction electronically, instead of on paper.
- Attribution: the signature is reliably associated with the record and with the person who signed it.
- Record retention: the signed document can be accurately reproduced later, for as long as it needs to be kept or referenced.
When it is not valid
Seven categories the ESIGN Act excludes.
The ESIGN Act carves out a short, specific list of document types where an electronic signature is not enough on its own. Check this list before you assume every document qualifies.
Wills, codicils, and testamentary trusts
ESIGN Act §103(a)(1) excludes these documents outright. They require a handwritten signature under the law of the applicable state.
Family law matters
Adoption, divorce, and other matters governed by state family law are excluded under ESIGN Act §103(a)(2).
UCC documents beyond Articles 2 and 2A
ESIGN Act coverage of the Uniform Commercial Code is limited to Article 2 (Sales) and Article 2A (Leases). Negotiable instruments, letters of credit, and other UCC instruments outside those two articles are excluded.
Court orders and official court documents
Pleadings, orders, and other documents required to be executed in connection with court proceedings must follow the applicable court rules, not the ESIGN Act.
Notices affecting essential services and housing
Cancellation or termination notices for utility service (water, heat, power), and notices of default, acceleration, repossession, foreclosure, or eviction under a rental agreement for a primary residence, are excluded.
Insurance and product-safety notices
Cancellation or termination notices for health or life insurance benefits, and product recall notices or notices of a material failure that risks health or safety, are excluded.
Hazardous materials transport documents
Documents required by law to accompany the transportation or handling of hazardous materials, pesticides, or other toxic materials are excluded.
How Kligrafia meets the standard
Built to satisfy the ESIGN Act and hold up under FRE 901.
- Explicit consent. Every signer sees and affirmatively agrees to sign and to conduct the transaction electronically before their signature is captured — logged in the audit trail.
- Identity verification. Verify signers by driver’s license or passport, with OCR and biometric checks at higher assurance levels, so attribution holds up if it is ever questioned.
- Verifiable evidence report. Every step is logged and chained with SHA-256 hashes and a trusted timestamp — if anyone alters the document afterward, the seal shows it.
- Public verifier. Anyone — including a court or opposing counsel — can check a signed document at /verify without an account or a login.

Frequently asked questions
What people ask before they sign.
Is an electronic signature legally binding in the United States?
- Yes, for the vast majority of contracts. The federal ESIGN Act (15 U.S.C. §7001 et seq.) states that a signature, contract, or record cannot be denied legal effect solely because it is in electronic form. UETA, adopted by 49 states as its state-law counterpart (New York uses its own analogous statute, ESRA), reinforces the same principle at the state level. As long as the signer intended to sign and consented to transact electronically, an e-signature carries the same legal weight as a handwritten one.
Do I need a witness or a notary for an electronic signature?
- Generally no, for an ordinary private contract. Kligrafia is not a notary public and this platform does not perform notarization or Remote Online Notarization (RON) — that is a distinct service performed by a commissioned notary or an approved RON platform. Some specific document types (real estate deeds, certain affidavits) do require notarization regardless of whether the signature itself is electronic; check your document type before you sign.
Is an electronically signed document admissible as evidence in court?
- Yes. The relevant evidentiary standard is Federal Rule of Evidence 901, which requires that a record be authenticated — you have to be able to show it is what you claim it is. Kligrafia's evidence report documents identity verification, a trusted timestamp, and the full hash-chained audit trail precisely to support that authentication standard, independently of Kligrafia.
Does every state accept UETA the same way?
- UETA has been adopted by 49 states, but each state can add its own variations when it adopts the uniform act. New York did not adopt UETA at all — it uses its own analogous statute, the Electronic Signatures and Records Act (ESRA), with a broadly equivalent effect. For a specific state or a specific document type, confirm the exact requirements with a licensed attorney in that state.
Is a signature from Kligrafia as valid as one from DocuSign or Adobe Sign?
- Yes. The ESIGN Act and UETA do not name a specific vendor or technology — they set out the requirements (intent, consent, attribution, retention) that any platform's process has to meet. What matters legally is whether the signing process meets those requirements and produces evidence that holds up under FRE 901, not which company built the software.
