Why Bother If It's Not Required?
Do not confuse oral agreement terms with proof of membership. In Andrew Nemeth Properties v. Panzica (2025), the Indiana Supreme Court held that becoming a member requires a written agreement or written confirmation. A disputed oral plan to give someone an interest did not establish membership.
- Bank documents: ask the institution what ownership and authority records it needs; it may request a written operating agreement.
- Written terms document ownership, governance and decisions. They do not guarantee liability protection or replace proper company records and separate finances.
- Prevents disputes — with multiple members, having terms in writing avoids disagreements over profit splits or decision-making down the road.

A Few Details Worth Knowing
- Not filed with the state — Indiana keeps the operating agreement entirely private; it's not part of your Articles of Organization filing.
- Costs nothing to draft yourself — you can write your own for free, though attorney-prepared agreements typically run $100–$200.
- Recommended even for single-member LLCs — it reinforces the separation between you and your business, protecting your personal assets.
- Can be updated any time — amend it as your business grows or circumstances change, as long as all members agree.
