Electronic Signature Laws by State: What You Need to Know

The Federal Foundation: ESIGN Act

The Electronic Signatures in Global and National Commerce (ESIGN) Act, signed into law in 2000, established a baseline that electronic signatures are legally valid and enforceable across all 50 states. Under ESIGN, a contract or signature cannot be denied legal effect solely because it is in electronic form.

However, ESIGN is a federal law, and states have the power to adopt their own electronic signature legislation — which most have done through the Uniform Electronic Transactions Act (UETA).

UETA: The State-Level Framework

The Uniform Electronic Transactions Act (UETA) was drafted by the Uniform Law Commission in 1999 to provide a consistent state-level framework for electronic transactions. As of 2026, 49 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands have adopted UETA in some form.

The lone holdout: New York. New York has not adopted UETA but instead enacted its own Electronic Signatures and Records Act (ESRA). While ESRA achieves similar goals, it differs in structure and some specific provisions — something businesses operating in New York need to be aware of.

Core Principles of UETA

• Consent required — Both parties must agree to conduct the transaction electronically. You can't force someone to accept an electronic signature.
• Attribution — The electronic signature must be attributable to the person who signed. This is typically established through email verification, IP logging, and audit trails.
• Record retention — Electronic records must be accessible and reproducible for the legally required retention period.
• No specific technology mandated — UETA does not require any particular type of electronic signature. A typed name, a click-to-sign button, or a drawn signature on a touch screen are all valid.

State-by-State Notable Differences

While UETA provides a uniform baseline, individual states have modified their adoptions in ways that matter. Here are the most significant variations:

New York

New York's ESRA takes a technology-neutral approach but includes specific provisions for state government transactions. For private transactions, ESRA functions similarly to UETA. However, New York state agencies have additional requirements for electronic signatures on government documents, including specific security standards published by the Office of Information Technology Services.

California

California adopted UETA in 1999 and has been one of the most e-signature-friendly states. California also has specific laws governing electronic notarization (remote online notarization became permanently authorized in 2024) and digital signatures for communications with state agencies through the California Government Code Section 16.5, which requires the use of a digital signature (certificate-based) for certain government filings.

Illinois

Illinois adopted UETA but also enacted the Electronic Commerce Security Act (ECSA), which provides additional provisions for digital signatures (a subset of electronic signatures that use encryption technology). Illinois makes a distinction between a general electronic signature and a "secure electronic signature" that carries a legal presumption of validity.

Florida

Florida's Uniform Electronic Transaction Act (F.S. 668.50) includes specific provisions for notarization. Florida was one of the first states to authorize remote online notarization (RON), and it remains one of the most RON-friendly states. If your business involves notarized documents, Florida's framework is among the most permissive.

Texas

Texas adopted UETA through the Texas Business and Commerce Code Chapter 322. Texas also has specific provisions for electronic documents in real estate transactions through the Texas Property Code and allows remote online notarization under the Texas Government Code.

Documents That Still Require Wet Signatures

Both ESIGN and UETA include explicit exceptions — certain documents that cannot be signed electronically. These include:

• Wills, codicils, and testamentary trusts — Most states require handwritten (wet) signatures on wills
• Family law documents — Adoption, divorce, and custody agreements in many states
• Court orders and notices — Official court documents generally require traditional signatures or specific court-approved electronic systems
• Notices of cancellation of utility services
• Notices of default, foreclosure, or eviction
• Notices of cancellation of health or life insurance
• Product recall notices
• Documents accompanying hazardous materials transport

Real Estate: A Special Case

Real estate transactions have historically been a gray area for electronic signatures, but the landscape has shifted dramatically. Most states now allow electronic signatures on real estate contracts, deeds, and mortgage documents, with the following caveats:

• County recorders may have specific requirements for electronically signed documents
• Some states require notarization for real estate documents, adding another layer of electronic signature considerations
• Title companies and lenders may have their own policies that are more restrictive than state law
• Remote online notarization (RON) is now authorized in over 45 states, making fully electronic real estate closings possible in most jurisdictions

Compliance Checklist for Businesses

If you use electronic signatures in your business (and you should), follow these guidelines to ensure compliance across all states:

1. Obtain consent — Before sending a document for electronic signature, confirm that the signer agrees to conduct the transaction electronically. Most e-signature platforms handle this automatically with a consent screen.
2. Verify signer identity — Use email verification, access codes, or knowledge-based authentication to establish that the signer is who they claim to be.
3. Maintain an audit trail — Log the timestamp, IP address, email address, and actions taken during the signing process. DottiSign does this automatically for every document.
4. Provide a copy — Give the signer a copy of the signed document. Under ESIGN, signers must be able to retain a copy of the electronic record.
5. Store securely — Retain signed documents in a secure, accessible system for the duration of any applicable retention period.
6. Check exclusions — Verify that the document you're signing electronically is not in the list of excluded document types for your state.

International Considerations

If your business operates internationally, be aware that electronic signature laws vary significantly by country:

Jurisdiction	Key Law	Approach
United States	ESIGN + UETA	Technology-neutral; most e-signatures valid
European Union	eIDAS Regulation	Three tiers: simple, advanced, qualified (qualified carries strongest legal weight)
United Kingdom	Electronic Communications Act 2000	Similar to EU pre-Brexit; most e-signatures valid
Canada	PIPEDA + Provincial Acts	Generally permissive; varies by province
Australia	Electronic Transactions Act 1999	Technology-neutral; broadly permissive

For most business-to-business and business-to-consumer transactions within the United States, a standard electronic signature through a platform like DottiSign meets all federal and state requirements. The key is ensuring your platform captures proper consent, attribution, and an audit trail.

Practical Recommendations

• Use a reputable e-signature platform — Tools like DottiSign are built to comply with ESIGN and UETA requirements automatically, including audit trails, consent capture, and document retention.
• Don't over-engineer it — For standard business contracts, a basic electronic signature is sufficient. You don't need certificate-based digital signatures unless your industry specifically requires them.
• When in doubt, check with a lawyer — If you're signing high-value contracts, documents with unique state requirements, or agreements in heavily regulated industries (healthcare, finance), consult an attorney familiar with your state's specific provisions.
• Keep up with legislative changes — Electronic signature laws continue to evolve, particularly around remote notarization. What required a wet signature three years ago may now be eligible for electronic signing.
