Are electronic signatures legal in the United States?
Electronic Signatures in Global and National Commerce Act (ESIGN, 2000) + Uniform Electronic Transactions Act (UETA)
Valid and legally equivalent to a handwritten signature for the vast majority of commercial and personal transactions.
Legally valid
Electronic signatures in United States
The US has two parallel frameworks. The federal ESIGN Act (2000) establishes that electronic signatures are legally equivalent to handwritten signatures for most transactions in interstate and foreign commerce. The Uniform Electronic Transactions Act (UETA) is a model law adopted by 49 states and the District of Columbia that extends this to intrastate transactions. New York has not adopted UETA; instead it enacted the Electronic Signatures and Records Act (ESRA), which covers similar ground.
What you need to know
- ESIGN requires that signers consent to conduct business electronically. This consent can be implicit from behavior (e.g. clicking 'I agree') or explicit.
- UETA is adopted in 49 states + DC. New York uses ESRA instead, with broadly similar outcomes.
- Electronic signatures must be attributable to the person who signed. An audit trail with IP, email, and timestamp satisfies this requirement.
- InkRobin produces a Simple Electronic Signature (SES). This is legally valid under ESIGN/UETA for virtually all commercial documents.
- Courts in all 50 states have routinely upheld electronically signed contracts.
State notes
New York has its own page. These states follow UETA and add the local points below.
California
California UETA, Cal. Civ. Code §1633.1 et seq. (adopted 1999)
- Parties must agree to transact electronically. Consent can be inferred from conduct, such as clicking a button or starting the transaction online.
- The Department of Real Estate allows electronic signatures on most real estate transactions, subject to both parties' consent.
- Arbitration clauses in employment agreements must be knowing and voluntary. An e-signed clause is valid but should carry clear consent language.
- An audit trail with IP address, email, timestamp and document hash supports attribution under UETA §9.
Texas
Texas UETA, Tex. Bus. & Com. Code ch. 322 (adopted 2001)
- §322.007: a contract cannot be denied effect solely because an electronic record was used in forming it.
- Texas courts have upheld e-signed arbitration clauses, employment agreements and real estate documents.
- The Texas Real Estate Commission permits electronic signatures on most standard forms, subject to both parties' consent.
- Attribution under §322.009 is supported by a record of the signing method, IP address, email and document hash.
- Notices of default, foreclosure or eviction under specific residential property law are excluded.
Common exclusions
These document types typically require a handwritten or notarized signature in United States.
- Wills, codicils, and testamentary trusts
- Court orders and official court documents
- Cancellation of utility services
- Recall notices and product safety information
- Documents governed by the Uniform Commercial Code (some sections, primarily negotiable instruments and Article 9 filings, though these have been updated to accommodate e-signatures in most states)
What InkRobin produces
InkRobin produces a Simple Electronic Signature (SES): the baseline tier under eIDAS and equivalent frameworks. SES is valid for most commercial contracts in United States. It is not a Qualified Electronic Signature (QES), it does not involve a digital certificate from a Certification Authority, and it is not a substitute for notarization.
