Is our electronically signed contract enforceable in Idaho, and can the other side insist on paper?

Yes, an electronic record or signature is legally recognized in Idaho, but ONLY for parties who agreed to transact electronically, and either party can still insist on paper for a given transaction. Idaho's Uniform Electronic Transactions Act, Idaho Code § 28-50-107(a)-(d): "A record or signature may not be denied legal effect or enforceability solely because it is in electronic form... A contract may not be denied legal effect or enforceability solely because an electronic record was used in its formation... If a law requires a record to be in writing, an electronic record satisfies the law... If a law requires a signature, an electronic signature satisfies the law." But the Act's own scope provision limits all of this to parties who opted in: Idaho Code § 28-50-105(b): "This chapter applies only to transactions between parties each of which has agreed to conduct transactions by electronic means. Whether the parties agree to conduct a transaction by electronic means is determined from the context and surrounding circumstances, including the parties' conduct." And § 28-50-105(c) preserves a standing right to switch back to paper for other transactions: "A party that agrees to conduct a transaction by electronic means may refuse to conduct other transactions by electronic means. The right granted by this subsection may not be waived by agreement." Two further limits come before any of that. Idaho Code § 28-50-103(a) applies the Act to electronic records and signatures "relating to a transaction" only "[e]xcept as otherwise provided in subsection (b) of this section", and (b) takes a transaction out to the extent it is governed by "[a] law governing the creation and execution of wills, codicils or testamentary trusts" or by the uniform commercial code, "other than section 28-1-306, Idaho Code", its sales chapter and its leases chapter. And § 28-50-105(a) says the Act "does not require a record or signature to be created, generated, sent, communicated, received, stored, or otherwise processed or used by electronic means or in electronic form."

The trap

Agreement to transact electronically is not all-or-nothing and not waivable in the other direction either: § 28-50-105(c)'s right to refuse electronic means for OTHER transactions cannot be waived by contract, so a broad clause purporting to commit the parties to conduct all future dealings electronically cannot lock a party out of insisting on paper for a later, different transaction. That non-waiver is the exception and not the rule: § 28-50-105(d) provides that "[e]xcept as otherwise provided in this chapter, the effect of any of its provisions may be varied by agreement", so the rest of the Act is default law a contract can rewrite. And § 28-50-107 carries a fifth subsection the writing-and-signature rules do not reach: where a law requires certified mail, electronic transmittal works only "with the express consent of the recipient." Do not assume electronic assent is established just because a document exists in electronic form: § 28-50-105(b) requires actual agreement to transact electronically, determined "from the context and surrounding circumstances, including the parties' conduct," which is a fact question the statute does not resolve by a signature's mere format. This rule is statute-only: no Idaho appellate decision mentions §§ 28-50-103, 28-50-105, 28-50-107 or 28-50-109, an honest gap for a chapter enacted in 2000 that appears not to have generated reported Idaho appellate litigation on these sections.
