ESIGN is the federal law. UETA is its state-level counterpart. They overlap heavily — but UETA is the one your in-state lawyer will reference for routine business contracts. Standard disclaimer: this is general information, not legal advice for your situation.
What UETA does
The Uniform Electronic Transactions Act was promulgated by the Uniform Law Commission in 1999 and has been enacted by 49 US states (every state except New York, which has its own Electronic Signatures and Records Act).
UETA says electronic signatures and records have the same legal effect as paper, provided the parties have agreed to transact electronically. Agreement is judged from context — not necessarily an explicit checkbox.
Agreement to transact electronically
UETA Section 5(b): agreement is determined from 'the conduct of the parties and the surrounding circumstances'. If you sent a contract by email and the other side signed and returned electronically, you've both agreed.
For consumers, additional protections apply — broadly aligned with ESIGN's consumer-consent rules. For business-to-business, agreement is usually implicit in the exchange.
Attribution and integrity
UETA Section 9: an electronic signature is attributable to a person if it was 'the act of the person'. The act can be shown 'in any manner' — including the security procedures used, the audit log, IP address, login credentials.
This is why audit trails matter. A challenge to a signature usually isn't 'is e-signing valid?' — it's 'did *this person* actually sign?'. Strong audit trails answer that.
The New York exception
New York didn't adopt UETA but has the Electronic Signatures and Records Act (ESRA) — substantively similar with some New York-specific quirks. For most practical purposes, the outcome is the same.
Illinois adopted UETA late (2021). Washington is also slightly different. For multi-state contracts, governing-law clauses usually pick one state's law to apply.
FAQ
Do I need to comply with UETA and ESIGN?
In practice they overlap. Compliance with one in a UETA state generally satisfies both. ESIGN applies as a federal floor.
Which states haven't adopted UETA?
Just New York, which has equivalent legislation. All other 49 states have UETA on the books.
Does UETA cover wills and trusts?
No — UETA carves out wills, testamentary trusts, and a short list of family-law and court documents. State law on those still typically requires wet ink.
Is a Flint signature UETA-valid?
Yes. Flint's signing tool captures intent, timestamp and document hash — the elements UETA looks for in an enforceable e-signature.
If you're contracting in any US state, UETA almost certainly applies. Sign in Flint and keep the audit log.
