Legal Guide
Yes. In the United States, electronic signatures have carried the same legal weight as handwritten ones since the ESIGN Act of 2000, backed at the state level by UETA in most states. This guide explains what those laws actually require, where wet ink is still the rule, and why the evidence around a signature matters as much as the signature itself.
This guide is educational content, not legal advice. Laws vary by state and by situation — consult a lawyer about your specific documents.
The Short Answer
Electronic signatures are legally binding in the U.S. for the vast majority of business, nonprofit, and personal documents — volunteer waivers, consent forms, grant agreements, employment contracts, donor pledges, board resolutions, vendor agreements, and more. Courts routinely enforce electronically signed contracts, and they have for more than two decades.
The important nuance is that the law doesn't bless a particular technology. It blesses a process. An electronic signature is valid when the signing process demonstrates a few specific things: that the signer meant to sign, that everyone agreed to do the transaction electronically, that the signature is tied to the actual document, and that a faithful copy of the signed record is kept. Get those right and a tap on a phone screen is just as binding as a pen stroke. Get them wrong and even an elaborate digital ceremony can fall apart under challenge.
The Legal Foundation
The Electronic Signatures in Global and National Commerce Act is the federal law that put electronic and handwritten signatures on equal footing. Its core rule is simple: a signature, contract, or record may not be denied legal effect solely because it is in electronic form. Because it's federal, ESIGN provides a nationwide baseline for transactions in interstate and foreign commerce — which covers most of what organizations sign day to day.
The Uniform Electronic Transactions Act is a model law that most states have adopted. It applies when the parties have agreed to conduct a transaction electronically, and it fills in the state-law details that ESIGN leaves open. One notable exception: New York never adopted UETA. Instead it uses its own Electronic Signatures and Records Act (ESRA), which reaches a similar result — electronic signatures are valid in New York too, just under a different statute.
How they fit together: ESIGN sets the federal floor, and each state's UETA (or New York's ESRA) governs the details in that state. For everyday documents, the practical takeaway is the same everywhere — a properly executed electronic signature is enforceable.
What The Law Requires
Under ESIGN and UETA, an electronic signature is legally equivalent to a handwritten one when these conditions are met.
The signer must take a deliberate action that shows they meant to sign — drawing a signature, typing their name into a signature field, or clicking a clearly labeled Sign button. Accidental clicks and buried checkboxes don't demonstrate intent.
The parties must agree to conduct the transaction electronically. In practice this is a disclosure the signer acknowledges before signing, confirming they're willing to sign electronically rather than on paper.
The signature has to be attached to, or logically associated with, the specific document that was signed. A signature floating in a separate file, disconnected from the agreement, doesn't satisfy this.
The signed record must be retained in a form that accurately reflects the agreement and can be reproduced later by everyone entitled to a copy. If you can't produce the signed document, the signature can't help you.
The Exceptions
ESIGN and UETA carve out categories of documents that generally still require a handwritten signature, extra formalities like witnesses and notarization, or both. The most common ones:
Wills, codicils, and testamentary trusts
Estate documents are generally excluded, though a growing number of states have passed electronic-will statutes — this is an area where state law is actively changing.
Family law documents
Adoption papers, divorce decrees, and similar family-law filings generally fall outside ESIGN and UETA.
Court orders and official notices
Court orders, notices, and other official court documents follow court rules, not e-signature statutes.
Certain UCC transactions
Some transactions governed by the Uniform Commercial Code sit outside the ESIGN and UETA framework and follow the UCC's own rules instead.
Treat these as "generally excluded — check your state." The boundaries differ from state to state and shift over time. For anything in these categories, or anything unusually high-stakes, ask a lawyer before relying on an electronic signature.
The Evidence
Here's the part most guides skip: a signature being legally valid and a signature being provableare two different things. If a signer later claims "I never signed that," the statute won't save you — evidence will. That's the job of an audit trail.
An audit trail is a timestamped log of everything that happened to a document: when it was sent, when it was viewed, how the signer's identity was verified, when each signature was applied, and from what IP address. A good one is also tamper-evident, meaning any alteration to the record after signing is detectable. In a dispute, that turns a memory-versus-memory argument into a contemporaneous documented record — which is why the audit trail is often the most valuable thing an e-signature platform produces.
How CTG Sign Delivers
CTG Sign is designed so every signature you collect meets the ESIGN and UETA requirements by default.
Intent to sign
Signers actively draw or type their signature and click a clearly labeled Sign button — a deliberate act that demonstrates intent.
Consent
Before proceeding, signers acknowledge that they're signing electronically, satisfying the consent requirement.
Association with the record
Each signature is cryptographically bound to the specific document content, so the signature and the record can't drift apart.
Record retention
Every action is logged with timestamps, IP addresses, and email verification records, and signed documents with their audit trails are retained for the duration of your account plus 7 years.
Identity is verified with an email one-time code, and signers never need an account — they follow a secure link and sign from any device.
CTG Sign is in private beta. We're onboarding nonprofits in small batches — some waitlist signups get free beta access, and everyone else is notified at launch. If your nonprofit needs legally binding signatures without enterprise pricing, join the list.

Yes. Under the federal ESIGN Act and state UETA laws, a signature cannot be denied legal effect solely because it is electronic. As long as the signing process shows intent to sign, consent to do business electronically, association of the signature with the record, and proper record retention, an electronic signature carries the same legal weight as ink on paper for most documents.
In practice, yes. Most states have adopted UETA, and New York — which never adopted UETA — has its own law, the Electronic Signatures and Records Act (ESRA), that reaches a similar result. The federal ESIGN Act also provides a nationwide baseline. Specific rules for unusual document types can vary by state, so check your state's requirements for anything high-stakes.
Categories generally excluded from ESIGN and UETA include wills, codicils, and testamentary trusts; family-law documents like adoption and divorce papers; court orders and official court notices; and certain transactions under the Uniform Commercial Code. These carve-outs vary by state — some states now permit electronic wills, for example — so check your state's law or ask a lawyer before relying on an e-signature for these.
An electronic signature is vulnerable when one of the four requirements is missing: there's no clear action showing the signer intended to sign, the signer never consented to doing business electronically, the signature isn't attached to or logically associated with the document, or no reproducible copy of the signed record was retained. Even a technically valid signature is harder to defend without an audit trail proving who signed, when, and that the document wasn't altered afterward.
It can be. The law cares less about the form of the signature — typed, drawn, or clicked — and more about the process around it. A typed name entered deliberately in a signature field, after consenting to sign electronically, with the signature associated to the record and retained, generally satisfies ESIGN and UETA. The evidence trail around the typed name is what makes it defensible.
No. Signers receive a secure link by email, verify their identity with a one-time code, and sign from any device — phone, tablet, or desktop — without creating a login or downloading an app.
If someone later claims they never signed a document, the dispute usually comes down to evidence. An audit trail is a timestamped log of every step — when the document was sent, viewed, and signed, the email identity verification, and the IP address involved. A tamper-evident trail turns a memory-versus-memory argument into a documented record, which is why it matters as much as the signature itself.
