Iowa LLC governance: a fiduciary floor the operating agreement cannot waive, and a state that hands you no forms

Iowa governs LLCs under the Revised Uniform Limited Liability Company Act, so it belongs with the states that keep the core fiduciary duties mandatory: the duties of loyalty and care and the obligation of good faith are a floor the operating agreement can shape but cannot eliminate. That puts Iowa against the freedom-of-contract states, where an agreement can reshape those duties far more freely. Iowa adds a practical quirk that raises the stakes on drafting. The state provides no fill-in-the-blank formation template and requires no written operating agreement, which sounds permissive and in practice means many Iowa LLCs run entirely on the statute’s defaults, including an equal-shares split that unequal partners rarely intend. Those are the features to understand, ahead of the general mechanics on the site’s default rules and freedom of contract guides.

The floor the agreement cannot cross

Start with what Iowa refuses to let the operating agreement do.

In Iowa, the operating agreement cannot eliminate the duties of loyalty and care or the obligation of good faith.

Under Iowa Code Section 489.409, members of a member-managed LLC, and managers of a manager-managed one, owe the duties of loyalty and care and an obligation of good faith and fair dealing. And Section 489.110 limits what the operating agreement can do with them: it may not eliminate the duty of loyalty, may not unreasonably reduce the duty of care, and may not eliminate the obligation of good faith, though it may identify categories of permitted activities and set standards so long as they are not manifestly unreasonable. So an Iowa operating agreement can channel and define the loyalty duty, tailoring it to a real estate operation with affiliated dealings, but it cannot contract it away, and a manager cannot draft himself out of accountability the way a Delaware or Kentucky agreement could.

The state that hands you nothing

Here is the Iowa-specific point that makes drafting matter more than owners expect.

Iowa provides no fill-in formation template and requires no written operating agreement, so an Iowa LLC that is not deliberately papered runs on the statute’s defaults.

Iowa does not publish a fill-in-the-blank Certificate of Organization; under Section 489.201 you draft your own document that meets the statutory requirements, and a common rejection is simply omitting the registered agent’s street address. Iowa also does not require a written operating agreement at all. The combination is deceptively permissive: an owner can form an Iowa LLC and never write an operating agreement, at which point every default in Chapter 489 governs the company, including the ones that do not fit. The most consequential of those is the split.

When an Iowa operating agreement is silent, distributions are shared equally among the members, regardless of who contributed more.

Under Iowa Code Section 489.404, distributions are shared equally among the members by default, a per-capita rule rather than one weighted by contribution, so a member who put in most of the capital receives the same share as one who put in little unless the operating agreement provides otherwise. For a real estate venture with unequal contributions, which is most of them, that default does not track the deal, and because Iowa neither hands you a template nor requires an agreement, the equal-shares default is exactly what an undocumented Iowa LLC ends up with. The lesson is that Iowa’s light-touch formation is not a reason to skip the operating agreement; it is the reason not to, because nothing else will set the split or use the room the act allows on duties. Management defaults to the members unless the agreement provides for managers.

The bottom line

Iowa uses the Revised Uniform LLC Act, so the duties of loyalty and care and the obligation of good faith are a floor the operating agreement cannot eliminate under Section 489.110.

Distributions default to equal shares under Section 489.404, so an LLC with unequal contributions must set the split in the agreement.

Iowa provides no fill-in formation template and requires no written operating agreement, so an undocumented Iowa LLC runs on the statute’s defaults.

That light-touch formation is a reason to draft the operating agreement, not to skip it, because nothing else sets the split or uses the room the act allows on duties.

An older Iowa LLC formed under the prior act should have its agreement read against Chapter 489, since the fit is not always clean.
