Does our no-assignment clause stop the other side from assigning its rights to be paid, or its rights under a license, permit or franchise?

Mostly no, for the categories Idaho's secured-transactions article protects. Idaho Code § 28-9-406(d) steps aside for subsection (e) and for §§ 28-9-407 and 28-12-303, subjects itself to subsection (h), and then provides that "a term in an agreement between an account debtor and an assignor or in a promissory note is ineffective to the extent that it: (1) Prohibits, restricts or requires the consent of the account debtor... to the assignment or transfer of, or the creation, attachment, perfection or enforcement of a security interest in, the account, chattel paper, payment intangible or promissory note; or (2) Provides that the assignment or transfer... may give rise to a default, breach, right of recoupment, claim, defense, termination, right of termination, or remedy." Idaho Code § 28-9-408(a), "[e]xcept as otherwise provided in subsection (b) of this section," extends the same override to promissory notes, health care insurance receivables, and GENERAL INTANGIBLES (expressly "including a contract, permit, license, or franchise"), making an anti-assignment clause ineffective to the extent it would impair the creation, attachment, or perfection of a security interest, or trigger a default merely because of the assignment. What the override does not do by itself is reroute the money. That is § 28-9-406(a)'s job, and it lets the account debtor keep paying the assignor "until, but not after, the account debtor receives a notification, authenticated by the assignor or the assignee, that the amount due or to become due has been assigned and that payment is to be made to the assignee."

The trap

Both overrides are narrower than a blanket rule that every anti-assignment clause is unenforceable. § 28-9-406(e) carves the override BACK OUT for a straight sale of a payment intangible or promissory note (as opposed to a security interest arising from one), "other than a sale pursuant to a disposition under section 28-9-610... or an acceptance of collateral under section 28-9-620", so an outright sale of a promissory note can still be blocked by a no-assignment clause in a fact pattern the statute does not reach. § 28-9-408 has the mirror-image limit in its own subsection (b): as to a payment intangible or a promissory note, subsection (a) applies "only if the security interest arises out of a sale" of it, outside the § 28-9-610 disposition and § 28-9-620 acceptance cases. § 28-9-408(d) is a further trap in the anti-assignment drafter's favor: even where subsection (a) makes the restriction "ineffective," the assignee still gets no enforcement right against the account debtor, no duty runs to the assignee, and the account debtor need not recognize the security interest or pay the assignee at all: the statute strips the anti-assignment clause of its power to create a DEFAULT, but does not force the account debtor to deal with a stranger. Subsection (d) goes further than that summary suggests: the secured party is also not entitled to use or assign the debtor's own rights, to reach "any trade secrets or confidential information" of the obligor, or "to enforce the security interest" in the note, receivable or intangible at all. § 28-9-406(h) separately preserves other law's protection for an individual account debtor who incurred the obligation for personal, family or household purposes: the consumer carve-out is not overridden by this section. And neither section reaches LETTER-OF-CREDIT RIGHTS; Idaho Code § 28-9-409 does that job on parallel terms, making a letter-of-credit term or a rule of law ineffective to the extent it "[w]ould impair the creation, attachment or perfection of a security interest in the letter of credit right" or would turn the assignment into a default. No Idaho appellate decision construes §§ 28-9-406(d), 28-9-408 or 28-9-409 as they now read, so every answer here comes from the statutory text. The section also excludes particular receivables outright: “This section does not apply to an assignment of a health care insurance receivable, an award of compensation made pursuant to the crime victims compensation act, chapter 10, title 72, Idaho Code, or a lottery prize subject to the provisions of chapter 74, title 67, Idaho Code.”
