Your counterparty is in Texas, you're in New York, the SAFE needs to close before the wire goes out tomorrow. Sign and scan won't make it. Is a click-to-sign enough? Will the cap table software accept it?
ESIGN and UETA together cover almost every commercial document in the US. The exceptions are narrower than people think — but they matter.
ESIGN and UETA in one paragraph
ESIGN is the federal statute (2000). UETA is the state-level uniform act adopted in 49 states (New York has its own equivalent). Between them, they confirm that an electronic signature has the same legal effect as a wet ink signature for almost all commercial transactions. The signer must intend to sign, consent to electronic transactions, and the signature must be attributable to them.
What's excluded
Wills, codicils, and trusts (in most states). Family law documents like adoption papers. Court orders. Certain notices about utilities, foreclosure, and product recalls. Negotiable instruments under the UCC. For everyday commercial work — contracts, NDAs, employment offers, vendor agreements, SAFEs — you're well inside the safe harbour.
Building defensible signatures
Use sign PDF and capture intent explicitly. The signer should see the full document before signing, click to consent to electronic transactions where required, and have access to the signed copy afterwards. The audit trail — IP, timestamp, signing events — is what defends the signature if challenged. Don't discard it.
Notarisation and witnessing
Where notarisation is required (real estate, some powers of attorney), online notarisation is now available in most states under remote online notarisation (RON) statutes. A regular e-signature alone doesn't replace a notary's seal. For documents that need witnessing, follow the witnessing requirement — most commercial documents don't require witnesses at all.
Practical patterns
For SAFEs, side letters, and standard commercial contracts, click-to-sign with a captured audit trail is standard practice. For real estate, employment paperwork crossing state lines, and anything touching regulated industries, check the specific document type's requirements before assuming electronic is acceptable. When in doubt, ask counterparty counsel.
FAQ
Does ESIGN require any specific signature technology?
No — it's technology-neutral. Any electronic process that captures intent and attribution can qualify. Audit trails make defending the signature easier.
Can I e-sign a will?
In most states, no. A handful have authorized electronic wills under specific procedures, but defaulting to wet ink remains safest.
Is a typed name enough?
Often yes — provided intent and attribution are clear. A drawn or uploaded signature backed by an audit trail is more defensible.
Are there any states where electronic signatures don't apply?
All 50 states recognize electronic signatures via ESIGN or UETA (or NY's equivalent). State-specific exceptions exist for narrow categories like wills.
Most US commercial documents can be signed in minutes from a browser. Use Flint's sign tool, preserve the audit trail, and only break out the notary for documents that genuinely need one. The SAFE closes before the wire.
