An Iowa LLC operating agreement is a written document that sets the rules for a limited liability company (LLC). It covers how the members deal with each other and with the company, how the business is run, and how the agreement can be changed.[2] Iowa law also treats an oral or implied agreement among the members as an operating agreement.[1] A written one gives every member the same record.

An LLC operating agreement lets you set your financial and functioning rules with your co-owners in a fashion that suits your business. Listed below are the state operating agreements our visitors research most often.
An Iowa LLC operating agreement is the agreement of all the members of a limited liability company, including a sole member. Section 489.102 of the Iowa Code says it counts whether or not it is called an operating agreement. It can be oral, implied, in a record, or any mix of those.[1] A company with one member can have one too.
"Operating agreement" means the agreement, whether or not referred to as an operating agreement and whether oral, implied, in a record, or in any combination thereof, of all the members of a limited liability company, including a sole member.
Under Section 489.105 of the Iowa Code, the operating agreement governs all of the following:[2]
That rule has exceptions. Some terms cannot be changed by agreement, and others can be changed only if the change is not manifestly unreasonable. The section on limits below explains both.
An oral or implied agreement can count, but a written one is much easier to prove. Write down what the members agreed, and have each member keep a signed copy.
Iowa LLCs are governed by chapter 489 of the Iowa Code, the Uniform Limited Liability Company Act. The chapter holds the definitions (section 489.102), the operating agreement provisions (sections 489.105 to 489.107) and the filing fees section (section 489.122).[3]
An Iowa LLC operating agreement records how the company will be owned and run. It can be written for one member or for several. Many people include the following parts, though the members choose their own terms within the limits the statute sets:
With several members, every member should agree on the terms before anyone signs. The agreement itself governs how it can be amended.[2] Unless the agreement sets its own steps, amending it takes the consent of all the members (Iowa Code § 489.407).[5] If the changes are large, a lawyer can check the wording. You can also browse our fillable LLC operating agreement page for other states.
An Iowa operating agreement can change some of the duties that members and managers owe, but not all of them. Section 489.105 lets the agreement alter certain fiduciary duties if the change is not manifestly unreasonable. It also lists provisions that an agreement can never change.[2]
If the term is not manifestly unreasonable, the operating agreement may do all of the following:[2]
The agreement may also specify how a specific act or transaction that would otherwise violate the duty of loyalty can be authorized or ratified. That approval comes from one or more disinterested and independent persons, after full disclosure of all material facts.[2]
In a member-managed company, an agreement can expressly relieve one member of a responsibility and place it on one or more other members. When it does, the agreement may also eliminate or limit the fiduciary duty of the member who was relieved, to the extent that duty went with the responsibility.[2]
An agreement may alter or eliminate the statutory indemnification for a member or manager. It may also eliminate or limit a member's or manager's liability to the company and its members for money damages. Exceptions apply to all of the following:[2]
Section 489.105 bars an operating agreement from doing any of the following. This is a plain-language summary of the main items:[2]
The statute lists a few more items. Read Section 489.105 in full before you sign, because it is the source for every limit above.
Whether a term is manifestly unreasonable is for the court to decide as a matter of law. The court may invalidate the term only if, given the company's purposes, activities and affairs, it is readily apparent that the term's objective is unreasonable or the term is an unreasonable way to reach that objective. The court judges the term as of the time it became part of the agreement. It considers only the circumstances that existed then.[2]
A term that cuts back member duties too far can be invalidated by a court.[2] Keep any change specific and reasonable, and ask a lawyer before you sign.

Yes. Iowa law defines an operating agreement as the agreement of all the members, so the members set its terms.[1] Under Section 489.105, the agreement governs member relations, the rights and duties of a manager, the company's activities and affairs, and how the agreement is amended.[2] The limits explained above still apply. You can start from the template on this page.
Under Section 489.105, to the extent the operating agreement does not provide for a matter, the Iowa LLC chapter governs that matter.[2] The statute's default rules fill the gaps. An oral or implied agreement among the members can also count as an operating agreement.[1] A written agreement lets the members choose their own terms instead of relying on the defaults.
