Electronic Signature Laws in Wyoming

Wyoming has adopted the Uniform Electronic Transactions Act (UETA), the model law drafted in 1999 and now enacted by nearly every state. In Wyoming it is codified in Title 40 (Trade and Commerce), Chapter 21 of the Wyoming Statutes, at Wyo. Stat. Ann. § 40-21-101 through § 40-21-119, where § 40-21-101 sets out the short title, "Uniform Electronic Transactions Act." The core rule appears in § 40-21-107: a record or signature may not be denied legal effect or enforceability solely because it is in electronic form, a contract may not be denied enforceability solely because an electronic record was used in its formation, and where a law requires a signature, an electronic signature satisfies that law. In short, a typed name, a drawn signature, or a click-to-sign action carries the same legal weight in Wyoming as ink on paper.

Wyoming's UETA works alongside the federal Electronic Signatures in Global and National Commerce Act (ESIGN Act, 2000), which applies in every state and validates electronic signatures and records in transactions affecting interstate or foreign commerce. ESIGN expressly allows a state to modify, limit, or supersede its provisions if the state has enacted the official UETA. Because Wyoming enacted a standard version of UETA, the two laws largely mirror each other, and Wyoming's statute is the primary source of state-law authority for e-signatures. The practical upshot is layered protection: where state UETA governs, it controls; for transactions touching interstate commerce, federal ESIGN provides an independent and consistent baseline. Both share the same foundational requirements — intent to sign, association of the signature with the record, and the parties' agreement to transact electronically.

Like the model act, Wyoming's UETA only applies to transactions where each party has agreed to conduct business by electronic means, and that agreement is determined from the context and surrounding circumstances (§ 40-21-105). The statute's scope provision, § 40-21-103, also carves out categories that cannot be handled with an ordinary e-signature. Wyoming UETA does not apply to a transaction to the extent it is governed by a law governing the creation and execution of wills, codicils, or testamentary trusts; by the Uniform Commercial Code (other than W.S. 34.1-1-107 and 34.1-1-206, and Articles 2 and 2A); or by the Uniform Computer Information Transactions Act. As a practical matter this means estate-planning instruments such as wills and most testamentary documents still generally require traditional execution. Many people also choose to keep court filings, certain notarized instruments, and real-property documents recorded with a county clerk on paper or use a compliant electronic process, since recording and notarization carry their own formalities. Separately, Wyoming permits remote online notarization (RON): the Wyoming Revised Uniform Law on Notarial Acts (Title 32, Chapter 3), enacted as SF0029 and effective July 1, 2021, authorizes Wyoming-commissioned notaries to perform notarial acts on electronic records using communication technology, which expands what can be completed fully online.

What does this mean in practice for signing online in Wyoming? For the vast majority of everyday agreements — employment offers, NDAs, vendor and service contracts, leases, sales orders, consents, and consumer agreements — a properly captured electronic signature is valid and enforceable in Wyoming. To make an e-signature hold up, focus on the same elements the statute emphasizes: show the signer intended to sign, confirm the parties agreed to do business electronically, keep the signature logically associated with the final document, and retain a complete, tamper-evident audit trail (who signed, when, and from where) along with a copy each party can store and reproduce. A platform that records consent, captures intent, and preserves a verifiable record gives you signatures that satisfy both Wyoming UETA and the federal ESIGN Act. For excluded documents like wills, or when a transaction requires notarization or county recording, confirm the specific formalities before relying on a standard e-signature.
