Idaho: LLC Operating Agreement Requirements

verified against the statute 2026-07-26 17 statute sources

The short answer

Idaho does not require an operating agreement, and the agreement may be oral, implied, in a record, or combined, including for a sole member. Unless different terms apply, the LLC is member-managed with equal rights, member majority for ordinary-course differences, unanimity for outside-course acts and amendments, equal interim distributions, unanimous later admission, economic-only transfers, and no agency power from membership alone.

Governing law and document nameIdaho Uniform Limited Liability Company Act; 'operating agreement' (Idaho Code §§ 30-25-101, 30-25-102(a)(9))
Required or optionalOptional; the Act governs matters the agreement does not address (Idaho Code § 30-25-105(a)-(b))
Permitted form and signaturesOral, implied, in a record, or combined; includes a sole member. No general agreement-level signature, witness, acknowledgment, or notary formality (Idaho Code § 30-25-102(a)(9))
Adoption timing and effectProspective initial members, including one prospective sole member, may agree before formation; terms become the agreement when the LLC forms. No general adoption deadline (Idaho Code §§ 30-25-106(c), 30-25-201(d))
Single member and assentSole-member agreement recognized; LLC is bound without separate assent, and each later member is deemed to assent (Idaho Code §§ 30-25-102(a)(9), 30-25-106)
Management and authority defaultsMember-managed unless the agreement uses manager-managed language; equal rights, member majority for ordinary-course differences, all members for outside-course acts. Membership alone creates no agency; filed statements may grant outsider authority (Idaho Code §§ 30-25-301-.302, 30-25-407(a)-(c))
Voting, economic, and transfer defaultsPer-capita management rights; equal interim distributions; later admission generally requires all members; transfer gives distributions, not management or ordinary information, rights (Idaho Code §§ 30-25-401(c), 30-25-404(a), 30-25-407(b)-(c), 30-25-502)
Nonwaivable rules and dutiesCannot eliminate good faith; loyalty, care, and other duties may be tailored only within statutory and manifest-unreasonableness limits. Information, dissolution, member-action, filing, misconduct-liability, and nonparty protections remain (Idaho Code §§ 30-25-105(c)-(e), 30-25-409-.410, 30-25-701(a)(4), 30-25-801)
Amendment, filing, and recordsDefault unanimous amendment in either management form; outsider-approval conditions are enforceable. Secretary of State will not accept the agreement for filing; internally it prevails over conflicting filed records, while relying outsiders may use the filing. Information access may carry reasonable restrictions (Idaho Code §§ 30-25-107(a), (d), 30-25-201(c), 30-25-407(b)(4)(B), (c)(3)(B), 30-25-410(h))

Requirements one by one

Governing law and document name

Idaho Code § 30-25-101 names the Idaho Uniform Limited Liability Company
Act. Idaho Code § 30-25-102(a)(9) defines “operating agreement” broadly enough
to cover oral, implied, record-form, combined, and sole-member terms.

Required or optional

The agreement is optional. Idaho Code § 30-25-105(a)-(b) lets it govern the
listed internal matters and makes Chapter 25 the fallback for a matter it does
not address. Formation instead occurs when the certificate becomes effective
under Idaho Code § 30-25-201(d).

Permitted form and signatures

Idaho Code § 30-25-102(a)(9) recognizes oral, implied, record-form, and combined
agreements. Chapter 25 states no general agreement-level signature, witness,
acknowledgment, or notarization formality.

Adoption timing and effect

Idaho Code § 30-25-106(c) permits prospective initial members to agree before
formation and permits one prospective sole member to assent to terms. Those
terms become the operating agreement when the LLC forms. The Act states no
general later-adoption deadline.

Single member and assent

Idaho Code § 30-25-106(a)-(b) binds the LLC without separately manifested assent
and deems each person who becomes a member to assent. Subsection (c) separately
validates preformation terms adopted by a prospective sole member.

Management and authority defaults

Idaho Code § 30-25-407(a)-(c) defaults to member management and equal management
rights. A member majority resolves ordinary-course differences; all members must
approve outside-course acts and amendments. Manager management exists only when
the agreement uses the statutory language or words of similar import.

Idaho Code § 30-25-301 says membership alone creates no agency. Idaho Code
§ 30-25-302(a), (c) provides the public statement-of-authority route for a
position's or person's power to transfer real property or otherwise bind the LLC
as to nonmembers.

Voting, economic, and transfer defaults

The default management vote is per person. Idaho Code § 30-25-407(b)-(c) gives
members or managers equal rights and uses a majority of people for ordinary-
course differences. Idaho Code § 30-25-404(a) also defaults interim
distributions to equal shares.

Idaho Code § 30-25-401(c) generally requires all-member approval for a later
member unless the agreement or a covered transaction supplies another route.
Idaho Code § 30-25-502(a)-(b) makes a transfer economic only: the transferee gets
distributions but not management or ordinary information rights.

Nonwaivable rules and duties

Idaho Code § 30-25-105(a)-(c) preserves good faith, reasonable information
rights, filing rules, dissolution grounds, member actions, misconduct liability,
and nonparty rights. Idaho Code § 30-25-105(d)-(e) permits loyalty, care, and
other fiduciary-duty changes only within the stated bad-faith, misconduct,
knowing-law-violation, and manifest-unreasonableness limits. Idaho Code
§ 30-25-409(d) supplies the contractual good-faith obligation.

The agreement cannot vary the judicial-dissolution grounds in Idaho Code
§ 30-25-701(a)(4) or unreasonably restrict the direct action described in Idaho
Code § 30-25-801(a). Information restrictions remain subject to the
reasonableness rule and company burden in Idaho Code § 30-25-410(h).

Amendment, filing, and records

Idaho Code § 30-25-407(b)(4)(B), (c)(3)(B) defaults to unanimous amendment in
either management form. Idaho Code § 30-25-107(a) also enforces an outsider-
approval or condition requirement written into the agreement.

Idaho is explicit about filing: Idaho Code § 30-25-201(c) says the Secretary of
State shall not accept operating agreements. Under Idaho Code § 30-25-107(d),
the agreement prevails internally over a conflicting effective filing, while a
relying outsider may use the filed record. Idaho Code § 30-25-410(h) permits
reasonable conditions on information access and use, but § 30-25-105(c)(8)
forbids unreasonable restrictions.

What trips people up

The defaults count people, not percentages. Equal management rights, a
member-majority ordinary vote, and equal interim distributions apply unless the
agreement changes them.

Membership alone creates no agency. A private management clause and a public
statement of authority serve different functions.

The agreement cannot be filed. The current formation section expressly says
the Secretary of State will not accept it.

Common questions

Can an Idaho LLC have an oral operating agreement? Yes. Idaho Code
§ 30-25-102(a)(9) expressly includes oral and implied terms.

Does a later member have to sign? Idaho Code § 30-25-106(b) deems a person
who becomes a member to assent, without a general separate signature rule.

Does a transferee automatically receive voting rights? No. Idaho Code
§ 30-25-502 separates distributions from management and ordinary information
rights.

This page is general legal information about state-law operating-agreement rules for an ordinary domestic limited liability company, not legal advice or a substitute for an agreement tailored to a particular company's owners, assets, financing, tax treatment, licenses, or disputes. A state may permit an oral, implied, or unsigned operating agreement while a separate law still requires a particular promise or transaction to be signed, recorded, approved, or disclosed. The statutory defaults apply when a valid agreement does not replace them, and some duties and remedies cannot be waived. Foreign LLCs, professional LLCs, series structures, and regulated businesses may face additional rules. Verified against the official statute text on the date shown; confirm current law and obtain licensed legal advice before relying on it for a particular company or transaction.
