Ohio does not require an LLC to have an operating agreement. You can file your articles of organization, pay the $99 fee, and operate legally without one. Chapter 1706 of the Ohio Revised Code explains how operating agreements work once they exist, but nothing in the chapter forces you to create one.1Ohio Legislative Service Commission. Ohio Code Title 17 Chapter 1706 Section 1706-081 That said, “not required” is not the same as “not important.” If you skip the agreement, Ohio’s default statutory rules govern your company, and those defaults rarely match what members actually intend.
What Counts as an Operating Agreement in Ohio
Ohio’s definition is broad. Under ORC Section 1706.01(R), an operating agreement is any valid agreement among the members about the LLC’s affairs and activities, whether written or oral. A sole member can also make a written declaration that serves as the agreement.2Ohio Legislative Service Commission. Ohio Revised Code Section 1706.01 So a handshake deal technically qualifies. Proving the terms of an oral agreement in court is another matter, and a written document eliminates that problem.
The agreement is private. Unlike your articles of organization, which go to the Ohio Secretary of State, the operating agreement stays with your company records. No state agency reviews it, approves it, or asks to see it.3Ohio Legislative Service Commission. Ohio Revised Code Section 1706.16
What Happens If You Don’t Have One
When your LLC has no operating agreement, Ohio’s default rules fill every gap. They are written as one-size-fits-all defaults, and they produce outcomes that catch members off guard.
Equal Profit Splits Regardless of Investment
Under the default rule, all members share equally in distributions made before dissolution. It does not matter whether one member put in $200,000 and another put in $5,000. Without an operating agreement saying otherwise, each gets the same share.4Ohio Legislative Service Commission. Ohio Revised Code Chapter 1706 This is the default that surprises people most often, because it feels deeply unfair to whoever put up the capital.
Every Member Helps Run the Business
Ohio LLCs are member-managed by default. Every member has the right to participate in directing the company’s activities. Ordinary business decisions are made by a majority of the members, and certain major actions require unanimous consent, including amending the operating agreement, taking action outside the ordinary course of business, and filing for bankruptcy.4Ohio Legislative Service Commission. Ohio Revised Code Chapter 1706 If you want a manager-managed structure where only designated people run day-to-day operations, you need an agreement that says so.
Members Can Freely Transfer Their Financial Interest
A member’s interest in an Ohio LLC is personal property and freely assignable. An assignment does not, by itself, make the recipient a member or strip the assigning member of their status.4Ohio Legislative Service Commission. Ohio Revised Code Chapter 1706 Without transfer restrictions in an operating agreement, any member can hand their financial interest to a third party you may not want anywhere near your business.
Dissolution Can Be Forced
Ohio’s default dissolution triggers include unanimous consent of the members, a court order finding it no longer reasonably practicable to carry on the business, and ninety consecutive days passing after the last remaining member dissociates.5Ohio Legislative Service Commission. Ohio Revised Code Section 1706.47 If your agreement does not address what happens when a member dies, becomes disabled, or wants out, the statutory defaults can force outcomes nobody planned for.
Why Written Beats Oral
Even though an oral agreement is legally valid in Ohio, it is a poor foundation. Memories drift. Members leave. New members join without ever hearing what was said. A written document records capital contributions, voting procedures, and distribution rules in a form a court can read. It also helps if someone sues the LLC and argues you treated the business as a personal piggy bank: written governance procedures support the claim that the company is a genuinely separate entity.
Ohio law gives written operating agreements broad power to customize the LLC’s rules. Under ORC Section 1706.08, a written agreement can expand, restrict, or even eliminate certain fiduciary duties that members and managers owe to each other and the company.4Ohio Legislative Service Commission. Ohio Revised Code Chapter 1706 That flexibility is where the LLC stops being a generic statutory creature and starts reflecting your actual business arrangement.
Single-Member LLCs Are Not Exempt From the Logic
If you are the only member, an operating agreement might sound pointless. Ohio law explicitly makes single-member operating agreements enforceable, which is a signal from the legislature that they serve a purpose.1Ohio Legislative Service Commission. Ohio Code Title 17 Chapter 1706 Section 1706-081
A single-member agreement documents the separation between your personal and business finances, which is your primary defense if a creditor tries to pierce the veil and reach your personal assets. It also establishes succession rules. Without a written plan for what happens if you die or become incapacitated, Ohio’s defaults govern, and the result may be dissolution rather than continuation under the person you would have chosen. Banks and lenders often ask for the agreement when you open a business account or apply for financing, so having one ready smooths those conversations.
What a Useful Agreement Covers
There is no mandatory format. A functional operating agreement focuses on the areas where Ohio’s defaults are most likely to cause problems. That generally includes each member’s ownership percentage and what they contributed in cash, property, or services; how profits and losses are allocated and when distributions happen; whether the LLC is member-managed or manager-managed and who has authority over daily decisions;6Wolters Kluwer. LLC Members vs. LLC Managers which decisions need a simple majority and which need supermajority or unanimous consent; whether and how a member can sell or assign their interest; the process for admitting new members; dissolution triggers beyond the statutory defaults;5Ohio Legislative Service Commission. Ohio Revised Code Section 1706.47 and what happens when a member wants to leave, retires, or dies, including how their interest is valued and paid out.
For a two-person LLC where one member provides the funding and the other provides the labor, overriding the equal-distribution default is the most urgent task. For a family LLC, succession planning may be the priority. Start with the defaults you want to override and build from there.
What Your Agreement Cannot Do
Ohio gives wide latitude to customize, but the limits are real. Under ORC Section 1706.08(C), the operating agreement cannot eliminate the implied covenant of good faith and fair dealing, change the LLC’s nature as a separate legal entity, or limit liability for bad-faith violations of good faith and fair dealing.4Ohio Legislative Service Commission. Ohio Revised Code Chapter 1706 You also cannot strip third-party rights the statute protects or override a court’s power to enforce Chapter 1706. These guardrails exist to prevent agreements that are technically valid but fundamentally abusive.
All members should sign the final document, and the executed original belongs with your company records alongside your articles of organization, financial statements, and tax returns.7Wolters Kluwer. Statutory Recordkeeping and Inspection Requirements for Corporations and LLCs The state will not ask to see it, but the moment a dispute, a bank, or a creditor does, you will be glad it exists.
