LLC Operating Agreement Requirements in Ohio

At a glance

Requirements one by one

Governing law and document name

Ohio's domestic LLC statute is the Ohio Revised Limited Liability Company Act (§ 1706.02). Section 1706.01(R) calls the internal arrangement an operating agreement and includes amendments in that term.

Required or optional

The Act does not command members to adopt an agreement. Section 1706.08(A) instead says Chapter 1706 governs an internal matter to the extent the operating agreement does not provide otherwise.

Permitted form and signatures

Section 1706.01(R) recognizes a written or oral agreement among members. A sole member has a narrower form rule: the definition requires a written declaration. The LLC Act adds no general witness, acknowledgment, or notarization condition. Particular obligations can have their own formality; for example, § 1706.281(A) makes a contribution promise unenforceable unless it is in a writing signed by the member.

Adoption timing and effect

Under § 1706.16(D), the agreement may be entered before, at, or after the articles filing and may take effect from the filing or another time stated in the agreement. Under § 1706.081(C), intended initial members agree that their terms become the operating agreement on formation. No general post-filing adoption deadline appears in those provisions.

Single member and assent

Section 1706.081(D) protects a one-member agreement from unenforceability merely because one person is the only party, subject to § 1706.01(R)'s written-declaration requirement. The LLC is bound without separately assenting, and an admitted member becomes a party and assents. Section Under § 1706.082(C), assignees and dissociated members are also bound to obligations governing those capacities.

Management and authority defaults

Section 1706.30 places direction and oversight with the members. A majority of members decides an ordinary-course matter, while every member must consent to an act outside the ordinary course. The agreement can designate managers and define their authority.

Authority to bind the company is a separate issue. Under § 1706.18, authority may arise under the agreement, under the member-direction rule, under other law, or through § 1706.19. An effective filed statement of authority is conclusive for a value-giving person who relies without contrary knowledge.

Voting, economic, and transfer defaults

Ohio's fallback vote is a majority of the members, not a majority of percentage interests (§ 1706.30(B)). Under § 1706.29(A), members receive equal shares of interim distributions. After formation, § 1706.27(B) lets the agreement control admission; otherwise every member must consent.

Assignment does not carry governance rights. Under § 1706.341, the assignee receives the assigned distributions but not management participation or company-record access. Admission as a member is a separate step.

Nonwaivable rules and duties

Ohio permits broad written modifications. Section 1706.08(B) allows a written agreement to expand, restrict, or eliminate fiduciary duties and related liability. It cannot eliminate the implied covenant of good faith and fair dealing or liability for a bad-faith violation of that covenant. Section 1706.08(C) also preserves the LLC's separate-entity nature, specified court power, the signed-writing rule for contribution promises, the bearer-certificate ban, and the statutory conditions for series liability limits. The member and manager rules in § 1706.31 and § 1706.311 state the loyalty, care, and good-faith defaults that apply unless validly changed.

Amendment, filing, and records

Section 1706.082(A) uses unanimous member consent unless the agreement authorizes another method; if it specifies conditions or a nonparty approval, those requirements control subject to the statutory waiver rules. The operating agreement itself is not a required public filing. Section 1706.16 requires the articles to state the name, statutory agent, and any applicable series notice, while allowing organizers or members to add other chosen matters.

Under § 1706.33, a member may inspect records the LLC maintains when the information is material to the member's rights and duties. The company may impose the stated reasonable restrictions and may keep qualifying sensitive information confidential; the section does not separately command retention of a written operating agreement.

What trips people up

• A sole member cannot rely on the oral-agreement option. Section 1706.01(R) permits member agreements to be written or oral but specifically defines the sole-member route as a written declaration.
• The statutory vote counts people, not percentages. Section 1706.30(B) says a majority of the members decides ordinary-course matters. Percentage-interest voting in a template is a negotiated replacement, not the Ohio fallback.
• Broad fiduciary flexibility requires a writing. Section 1706.08(B) reserves expansion, restriction, or elimination of duties and liability for a written operating agreement.

Common questions

Can an Ohio agreement require a nonmember's approval for amendments? Yes. Section 1706.082(A) recognizes an amendment method that requires approval from a nonparty or satisfaction of stated conditions, and explains how those requirements may be waived.

Does assigning the membership interest remove the assignor as a member? Not by itself. Section 1706.341(A)(2) says the assignment alone does not cause the member to cease being a member; the assignee receives the transferred distributions without automatic governance rights.

Can the LLC keep trade secrets from a member? Section 1706.33(E) permits reasonable access restrictions and allows the LLC to keep qualifying trade-secret or other sensitive information confidential for a reasonable period under the stated good-faith standard.
