eSignature Legality in the United States
Electronic signatures are fully legally binding in the United States for the vast majority of business, consumer, and government transactions. Two laws work together to establish this: the federal ESIGN Act and the state-level UETA.

Governing Law
ESIGN Act (Electronic Signatures in Global and National Commerce Act)
Passed by Congress in 2000, the ESIGN Act is a federal law that gives electronic signatures and records the same legal weight as paper and ink, for any transaction that affects interstate or foreign commerce. It's the reason a contract can't be thrown out purely because it was signed on a screen instead of paper.
UETA (Uniform Electronic Transactions Act)
Drafted by the Uniform Law Commission in 1999, UETA is a model law that individual states adopt to govern electronic transactions within their own borders. It has now been adopted in some form by 49 states, plus the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. New York is the lone holdout: it uses its own, similar law, the Electronic Signatures and Records Act (ESRA), instead.
Together, ESIGN handles interstate and international transactions while UETA (or New York's ESRA) governs transactions within a state, and in practice, the two frameworks are aligned closely enough that compliant platforms satisfy both automatically.
What Makes a Signature Valid Under U.S. Law
Both ESIGN and UETA test for the same four requirements:
1. Intent to Sign
The signer must have clearly intended to sign, just like with a wet-ink signature.
2. Consent to Do Business Electronically
Parties must agree to conduct the transaction electronically. For consumer transactions specifically, the business must also confirm the consumer can access and retain the electronic record.
3. Association of Signature With the Record
The system used must keep a record showing how and when the signature was created and tied to the document.
4. Record Retention
Signed electronic records need to be retained and reproducible, accurately reflecting the agreement.
There's no requirement for a specific technology. A typed name, a drawn signature, a clicked "I Agree" button, or a cryptographic digital signature can all satisfy the law, provided the four elements above are met.
When U.S. eSignatures May Not Be Accepted
A short list of document types are generally excluded from ESIGN and UETA and still require a wet-ink signature:
- Wills, codicils, and testamentary trusts
- Documents governed by the Uniform Commercial Code (certain negotiable instruments)
- Family law documents, including adoption, divorce, and other court orders
- Court notices and certain government filings
- Notices of cancellation of utility services, insurance, or health benefits (in some states)
- Product recall notices and documents related to the handling of hazardous materials
If your document falls into one of these categories, confirm the specific requirement with a qualified legal professional before sending it electronically.

Common questions about eSignature legality in the United States.
Yes. Inkfree signatures are fully binding under the ESIGN Act and UETA, backed by a court-admissible audit trail that captures signer identity, IP address, timestamp, and consent. Learn more.
Almost. 49 states plus D.C., Puerto Rico, and the U.S. Virgin Islands have adopted UETA. New York uses its own similar law (ESRA) instead. In practice, a compliant eSignature platform satisfies the requirements of all 50 states.
Generally no, most business contracts don't require witnesses whether signed on paper or electronically. Some document types (certain wills, specific real estate documents in some states) may still require witnesses or notarization regardless of signature method.
Yes, but the ESIGN Act adds an extra consent requirement for consumer transactions: the business must confirm the consumer can access, and reasonably retain, the electronic record before proceeding.
