What Is an LLC Operating Agreement?

Ohio does not require you to file an operating agreement with the Secretary of State, but skipping it is a mistake. The agreement is the internal contract describing who owns the LLC, how decisions get made, and what happens if a member leaves.

What goes inside

Typical sections cover member names and ownership percentages, capital contributions, profit distributions, management structure (member-managed vs manager-managed), voting thresholds, buy-sell triggers, and dissolution steps.

Single-member LLCs still benefit—banks want to see the document proving you are the authorized signer.

Operating agreement vs. Articles of Organization

Articles of Organization are the public formation filing. The operating agreement is private—kept with company records. Articles say the LLC exists; the agreement says how it runs.

When you must customize

  • Multiple founders with unequal equity
  • Silent investors vs. active managers
  • Family businesses passing ownership
  • Trucking fleets adding a second member for equipment splits
  • Converting from sole prop with existing contracts

Ohio default rules without an agreement

Ohio LLC statute supplies default rules when owners stay silent—often not what you intended. Written agreements override many defaults when properly drafted.

Disputes between members without a written buy-sell clause end up in expensive litigation using statutes neither side would have chosen upfront.

Amending the agreement

Adding a partner, changing profit splits, or converting to manager-managed governance requires signed amendments stored with the original. Banks may ask for the latest version when increasing credit lines.
