Indiana LLC governance: an act named for flexibility whose flexibility only exists once you sign a written agreement

Indiana called its LLC statute the Business Flexibility Act, and it means it: the act’s stated policy is to give maximum effect to the principle of freedom of contract, and it lets an operating agreement eliminate fiduciary duties outright, something many states will not allow. It even recognizes an oral or implied operating agreement as binding. Read all that and you would assume an Indiana LLC owner has wide latitude and does not need much paperwork. The opposite is true in the way that matters most. Every power that makes the act flexible, eliminating duties, capping liability, indemnifying managers, creating officers, takes effect only in a written operating agreement. Without a signed writing, the flexibility evaporates and the owner inherits the strictest defaults the act provides.

That inversion is the thing to understand about Indiana governance, and it is why the state’s contractarian reputation is a trap for the owner who takes it at face value and never signs an agreement. This page leads with the writing requirement rather than re-teaching the general mechanics on the site’s default rules and freedom of contract guides. In Indiana, the freedom is real, and it is entirely conditional on a document most single-member owners never bother to create.

The freedom the act promises

Start with the promise, because it is genuine and it is broad.

Indiana’s Business Flexibility Act declares that its policy is to give maximum effect to freedom of contract, and it lets a written operating agreement eliminate fiduciary duties entirely.

IC 23-18-4-13 states that the policy of the act is to give the maximum effect to the principle of freedom of contract and to the enforceability of operating agreements, and Indiana courts quote it directly. IC 23-18-4-4(a) then delivers on it: a written operating agreement may modify, increase, decrease, limit, or eliminate the duties, including fiduciary duties, or the liability of a member or manager for breach. It may provide indemnification, create officers, and give non-members approval rights. This is a stronger grant than many states allow, because Indiana does not impose an explicit statutory floor of good faith on what you can eliminate. Indiana also declined to adopt the uniform LLC act; a 2011 study commission looked at RULLCA and concluded that wholesale enactment was not desirable, so Indiana kept its own 1993 act. That is why Indiana’s defaults diverge from the RULLCA states this site has covered, Pennsylvania, Arizona, and Minnesota. The freedom is the selling point. The condition on it is the catch.

The catch: it only works in writing

Here is the sentence that changes how you should treat an Indiana LLC.

An oral or implied operating agreement is valid in Indiana, but it cannot modify duties, cap liability, or exercise any of the flexibility the act is named for, because those powers require a written agreement.

IC 23-18-1-16 defines an operating agreement as any written or oral agreement of the members, so an unwritten agreement is binding as far as it goes. But IC 23-18-4-4 grants the important powers only to a written operating agreement. So an owner operating on a handshake has an enforceable agreement about ordinary matters and none of the flexibility. Every duty-elimination clause, every liability cap, every indemnification promise made orally is void for lack of a writing. The practical result is stark. The owner who chose Indiana because it is flexible, and then never signed an operating agreement because the act allows oral ones, gets an entity with full fiduciary duties, no liability modifications, and no indemnification, the least flexible version of an Indiana LLC. The flexibility is not automatic. It is a document, and the document is the whole point.

What you inherit if you skip the writing

The defaults are not neutral gap-fillers. They are the strict end of the act.

Without a written operating agreement, an Indiana member is held to common-law fiduciary duties and the statutory duty to account as a trustee for benefits taken without consent.

IC 23-18-4-2(b) provides that, absent a written operating agreement, each member and manager must account to the company and hold as trustee any profit or benefit derived without the consent of the disinterested members or managers. On top of that statutory duty, Indiana courts apply common-law fiduciary duties to LLC members where the agreement has not modified them, as in Purcell v. Southern Hills Investments. So the owner without a writing is not lightly regulated; he is a fiduciary by default, exactly the status IC 23-18-4-4 exists to let him escape, and cannot escape without the document. IC 23-18-4-2(a) does supply one favorable default: absent a written agreement, a member or manager is not liable to the company for action or inaction unless it rises to willful misconduct or recklessness. But that shields conduct; it does not give the owner the control, allocation, and indemnification powers that only a written agreement unlocks.

The distribution default that follows the money

On distributions, Indiana sits with the minority whose silent rule rewards the funder, which separates it cleanly from the uniform-act states.

When an Indiana agreement is silent, profits and distributions are split by the agreed value each member contributed, not equally by headcount.

Under IC 23-18-5-3 and IC 23-18-5-4, if the operating agreement does not provide otherwise, profits, losses, and distributions are allocated on the basis of the agreed value of each member’s contributions. That is the opposite of the per-capita default in Pennsylvania, Michigan, Arizona, and Washington, where silence produces an equal split regardless of who funded the company. So an Indiana LLC where one member put in the capital and another put in the work will, by default, distribute in proportion to the recorded capital, and the sweat-equity member gets nothing for effort unless the agreement says so. This is where governance meets the tax return: a default that allocates by contribution, with no built-in special allocation for services, means the partner who expected a handshake fifty-fifty split is under-allocated until a written agreement and a valid allocation fix it, and on the federal side any special allocation still has to satisfy the substantial-economic-effect rules to hold up. The distributions guide covers why the split should be set deliberately; the Indiana point is that silence here does not default to fairness, it defaults to whoever wrote the bigger check.

The defaults that fill the rest

Two more defaults are worth setting rather than inheriting.

An Indiana LLC is member-managed by default and decides ordinary matters by a majority in interest, which is weighted by contribution, not by head.

Under IC 23-18-4-1, management is vested in the members unless the articles of organization provide for one or more managers, so an Indiana LLC is member-managed unless you say otherwise in the public filing. Under IC 23-18-4-3, ordinary decisions require the affirmative vote of a majority in interest of the members, which tracks the contribution weighting rather than counting heads, while certain fundamental acts require unanimous consent. The through-line for all of it is the writing requirement: management structure, voting thresholds, distribution splits, and duty modifications are all things the act lets you set, and almost none of them take their intended shape without a signed written operating agreement. In Indiana, the document is not a formality you can defer. It is the mechanism that turns the act’s flexibility from a promise into a rule your company actually runs on.

The bottom line

Indiana’s Business Flexibility Act promises maximum freedom of contract under IC 23-18-4-13 and lets a written operating agreement eliminate fiduciary duties under IC 23-18-4-4, a broad grant with no explicit statutory good-faith floor.

An oral or implied operating agreement is valid under IC 23-18-1-16, but it cannot exercise any of that flexibility, because the powers that matter require a written agreement.

Skip the writing and you inherit the strict defaults: common-law fiduciary duties and a statutory duty to account as trustee under IC 23-18-4-2(b), the opposite of what the act’s name suggests.

The distribution default under IC 23-18-5-3 and IC 23-18-5-4 splits by contributed value, not per capita, so a silent agreement rewards the funder and under-allocates the member who contributed effort.

Management defaults to the members under IC 23-18-4-1 and decisions run on a majority in interest under IC 23-18-4-3, so the plan in Indiana is to sign a written agreement that sets duties, allocations, and control deliberately, because none of the flexibility is automatic.
