Are electronic signatures legal in Idaho?
Yes. Idaho's Uniform Electronic Transactions Act makes an electronic signature satisfy any law that requires a signature, between parties who have agreed to do business electronically. Idaho also lets a certified-mail notice go electronically if the recipient expressly consents.

What Idaho Code chapter 28-50 says
Idaho adopted the Uniform Electronic Transactions Act in 2000 (Session Laws 2000, chapter 286). It's codified at Idaho Code §§ 28-50-101 to 28-50-120, in the title on commercial transactions. The heart of it is § 28-50-107:
- A record or signature can't be denied legal effect just because it's electronic.
- A contract can't be denied legal effect just because an electronic record was used to form it.
- An electronic record satisfies a law that requires a writing, and an electronic signature satisfies a law that requires a signature.
An electronic signature is any electronic sound, symbol or process attached to or logically associated with a record and adopted with intent to sign (§ 28-50-102). In court, evidence can't be excluded just because it's electronic (§ 28-50-113).
Certified mail, electronically
If a law requires any notice or other record to be sent by certified mail, the record may, with the express consent of the recipient, be transmitted electronically.
Idaho added that sentence in 2003. It isn't in the uniform act. The condition is express consent from the recipient, so get a clear yes in writing before you rely on it. Without that, § 28-50-108(b) still requires a record to go by whatever method another law specifies.
Agreement comes first
The act applies only to transactions where each party has agreed to deal electronically, and that's judged from context and conduct (§ 28-50-105(b)). Agreeing once doesn't commit anyone to the next deal: a party can refuse to do other transactions electronically, and that right can't be waived (§ 28-50-105(c)). When a law requires information in writing, an electronic copy only works if the recipient can print or store it (§ 28-50-108(a)).
What's excluded in Idaho
- Wills, codicils and testamentary trusts (§ 28-50-103(b)(1)).
- The Uniform Commercial Code, except § 28-1-306 and the chapters on sales (chapter 2) and leases (chapter 12) of goods (§ 28-50-103(b)(2)).
That's a short list. Idaho didn't add state-specific notice exclusions, so for anything else, check whether the law behind the document sets its own delivery or signing rules.
Idaho and the federal ESIGN Act
Federal law points the same way. The ESIGN Act gives electronic signatures effect in interstate commerce (15 U.S.C. § 7001) and lets a state's UETA modify or supersede parts of it (§ 7002). ESIGN carves out some notices (§ 7003), such as utility shutoffs and foreclosure or eviction notices for a primary residence, and adds consent steps before giving consumers required information electronically. Our guide explains how the two fit together.
Notaries and remote notarization
If a law requires notarization, the notary's electronic signature plus the required information satisfies it (§ 28-50-111). Since 2019, Idaho Code § 51-114A also lets a notary in Idaho perform a notarial act for a remotely located person who appears by live audio and video. See remote online notarization. SignMaster doesn't notarize documents.
Practical notes
- Keep the consent. Save the agreement to sign electronically, and any express consent to electronic delivery under § 28-50-107(e).
- Retain the final version. An electronic record satisfies a retention law if it accurately reflects the final document and stays accessible (§ 28-50-112).
- Plan how you'd prove who signed. Section 28-50-109 accepts any proof, including how well your security procedure works.
SignMaster keeps the first kind of consent for you: every signer agrees to sign electronically before signing, and that's recorded with the disclosure version. Express consent to certified-mail delivery under § 28-50-107(e) is a separate yes you collect yourself. The completed PDF, which signers can download, carries a certificate of completion with each event's timestamp.
Questions? Answers.
Can I email a notice that Idaho law says must go by certified mail?
Only with the recipient's express consent (§ 28-50-107(e)). Get that consent clearly and keep a record of it. If the notice is also covered by a federal rule or another statute, check with an Idaho attorney.
Is an e-signed contract enforceable in Idaho?
Idaho law says a contract can't be denied legal effect just because an electronic record was used to form it (§ 28-50-107(b)). Whether a particular contract is enforceable still depends on contract law and the facts.
Can a will be signed electronically in Idaho?
The UETA can't help there. Section 28-50-103(b)(1) leaves wills, codicils and testamentary trusts to their own law, so have an Idaho estate attorney handle the signing.
