UETA vs the ESIGN Act
Two laws, the same destination. The ESIGN Act is federal and applies to transactions in or affecting interstate commerce. UETA is a model act adopted state by state. Most of the time they agree, which is why the difference rarely matters — until it does.
The question people are really asking
Nobody wants a comparative law lecture. They want to know which rules apply to the contract in front of them, whether a signature will hold, and whether the state they operate in changes anything. The answer is usually: apply UETA as adopted in your state, and treat the ESIGN Act as the floor beneath it. Two situations break that rule, and both are worth knowing.
What the template covers
ESIGN is the federal floor
It guarantees that an electronic signature cannot be rejected solely for being electronic, across every state, for transactions affecting interstate commerce. Nothing a state does can remove that floor for those transactions.
UETA is how 49 states say the same thing
Adopted in every state except New York, UETA gives electronic records and signatures the same effect as paper within that state's law, and adds detail ESIGN leaves out — attribution, errors in transmission, and the effect of an automated agent.
A state can supersede parts of ESIGN
Section 7002 permits a state that has enacted UETA in its official form to modify or supersede the federal provisions. This is why the operative text for most domestic transactions is the state statute, not the federal one.
New York took its own route
New York never adopted UETA. It reaches an equivalent result through the Electronic Signatures and Records Act, codified at State Technology Law § 304, which gives electronic signatures the same validity and effect as handwritten ones.
The provisions that matter
ESIGN: 15 U.S.C. § 7001(a) for the general rule, § 7001(c) for consumer consent, § 7002 for the interaction with state law, § 7003 for exclusions. UETA: section 7 gives records and signatures legal effect, section 9 covers attribution, section 10 covers changes and errors, and section 12 covers retention. New York: State Technology Law § 304. UETA's exclusions are narrower than ESIGN's in some states and identical in others, which is one more reason to read the version your state enacted rather than the model text.
A multi-state lease portfolio and one outlier
A property manager standardised electronic signing across leases in eight states and assumed one process would serve all of them. Seven were straightforward. The New York properties raised a question from counsel that took two weeks to close out — not because electronic signatures are invalid there, but because the authority is a different statute and nobody on the team could point to it. The process did not change. The documentation of why it was sound did.
Questions people ask about this
If my state has UETA, does ESIGN still apply?
Yes, as a floor for transactions in or affecting interstate commerce. Where the state has adopted UETA in its official form, § 7002 lets the state provisions govern. In practice the outcome is the same for the overwhelming majority of contracts.
Are UETA exclusions the same as ESIGN exclusions?
Not always. UETA excludes wills, codicils and testamentary trusts and most of the UCC, and some states added their own carve-outs when they enacted it. Always check the enacted state version rather than the model act.
Does Illinois or Washington differ?
Both have adopted UETA, Illinois replacing an earlier electronic commerce statute. Where a state modernised an older act, transitional provisions occasionally matter for older records — rarely for new ones.
Which should a contract name as governing?
Contracts generally name a governing state law rather than a signature statute. Naming the state is what determines which version of UETA, or which alternative, applies to the signature question.
