Yes. Electronic signatures are legally binding in all 50 US states, and have been since 2000. The state a signer lives in almost never decides whether their e-signature holds up. What matters is whether the signing process captured intent, consent, a clear link between the signer and the document, and a retained record you can produce later if the agreement is ever challenged.
The two laws that make e-signatures binding nationwide
Two layers of law cover electronic signatures in the United States. At the federal level, the ESIGN Act (the Electronic Signatures in Global and National Commerce Act, in force since 2000) gives an electronic signature the same legal effect as a handwritten one for transactions in interstate or foreign commerce. Because it is federal law, ESIGN reaches every state.
At the state level, 49 states have adopted the Uniform Electronic Transactions Act (UETA), a model law from 1999 that establishes the same equivalence for transactions governed by state law. New York is the one state that never adopted UETA. Instead it relies on its own Electronic Signatures and Records Act (ESRA), which reaches the same result. So whether a transaction falls under federal or state law, and whichever state you are in, a properly executed e-signature is enforceable.
What actually makes an e-signature hold up
Enforceability comes from how the signature was collected, not from the technology or the state. Four elements matter. First, intent to sign: the signer takes a deliberate action to sign, such as typing their name or drawing a signature. Second, consent to do business electronically: for consumer agreements, ESIGN requires that the person affirmatively agrees to use electronic records and can access them. Third, attribution: the record should tie the signature to the specific signer through evidence like an email address, IP address, and timestamp. Fourth, record retention and integrity: you keep a tamper-evident copy of the signed document along with an audit trail, and can reproduce it accurately later.
That audit trail is the part teams most often overlook. If an agreement is ever disputed, the audit trail, capturing who signed, when, from what IP address, and which version of the document, is the evidence that makes the signature defensible. A typed name with no surrounding record is far weaker than the same signature backed by a complete event history.
The documents e-signatures do not cover
ESIGN and UETA carve out a short list of documents that still require paper or wet-ink signatures. These include wills, codicils, and testamentary trusts; documents related to adoption, divorce, and other family-law matters; court orders and official court documents; and certain notices tied to a person's home, such as foreclosure, eviction, and utility shutoff notices. Cancellation of health or life insurance benefits and recall notices for products that risk health or safety are excluded too. For everyday business agreements like contracts, NDAs, order forms, and onboarding paperwork, e-signatures are fully valid.
If you are collecting signatures programmatically and want the audit trail handled for you, a platform built for it removes the guesswork. Anvil's Etch e-sign produces legally binding signatures with a complete audit trail and tamper-evident records on every packet, so the consent, attribution, and retention pieces are covered without you assembling them by hand.
