A Connecticut LLC operating agreement is an agreement that governs relations among the members of a limited liability company (LLC) and between the members and the company.[1.2] The statute fills in anything the agreement leaves out.[1.3] It also names terms an agreement cannot change.[1.1] You can fill out our free single-member form online or download it as a PDF.

Connecticut’s LLC statute provides for an operating agreement to govern a company’s internal affairs. The agreement governs four matters, and the statute fills in whatever the agreement does not cover. Both rules are in Section 34-243d of the Connecticut General Statutes and are explained below.
Under Section 34-243d(a), the operating agreement governs the following.[1.2]
Section 34-243d(b) fills the gaps. Its own words are quoted below.
To the extent the operating agreement does not provide for a matter described in subsection (a) of this section, the provisions of sections 34-243 to 34-283d, inclusive, govern the matter.
Our form is a single-member, manager-managed agreement. If your LLC has more than one member, use the multi-member template linked in the next sections.
Connecticut law shields the owners whether or not the company has an operating agreement. Under Section 34-251a(a), a member or manager is not personally liable for a debt, obligation or other liability of the company solely by reason of being or acting as a member or manager.[1.6]
A person who becomes a member of a Connecticut LLC is deemed to assent to the operating agreement. The company is bound by the agreement too. It may enforce the agreement, whether or not the company has itself manifested assent to it.[1.4]
Read the agreement before you join a company, because joining means the statute treats you as agreeing to its terms.[1.4]
The agreement also reaches people who are no longer full members. The obligations of the company and its members to a person as a transferee, or to a person dissociated as a member, are governed by the operating agreement.[1.5]
The statute covers both kinds of company. One person intending to become the initial member may assent to terms that become the operating agreement when the company is formed. Two or more persons intending to become the initial members may make an agreement that becomes the operating agreement on formation.[1.4]
Our free form is the one-member type. If your LLC will have two or more members, use our multi-member form instead.
An operating agreement gives the members room to set their own terms, but not unlimited room. Under Section 34-243d, an agreement may not vary the law applicable under Section 34-243c. It also may not vary the company’s capacity to sue and be sued in its own name. The statute names more limits, listed below.[1.1]
Within those limits, an operating agreement may adjust some duties, as long as the change is not manifestly unreasonable. The statute lets the agreement do the four things below, so long as the result stays within the limits listed above.[1.1]
The agreement may not authorize conduct involving bad faith, wilful or intentional misconduct, or knowing violation of law.[1.1]
The agreement may also specify a method for a specific act or transaction that would otherwise violate the duty of loyalty. One or more disinterested persons may authorize or ratify it after full disclosure of all material facts.[1.1]
A second rule applies to a member-managed LLC. Suppose the agreement expressly relieves a member of a responsibility the member would otherwise have under Sections 34-243 to 34-283d. Suppose it also imposes that responsibility on one or more other members. Then the agreement may also eliminate or limit any fiduciary duty of the relieved member that would have pertained to that responsibility.[1.1]
If a member challenges a term as manifestly unreasonable, the court makes its determination as of the time the term became part of the operating agreement. It considers only circumstances existing at that time.[1.1]
The court may invalidate the term in only one of two situations. Either it is readily apparent that the objective of the term is unreasonable, or the term is an unreasonable means to achieve its objective. The court weighs this in light of the purposes, activities and affairs of the company.[1.1]
The operating agreement governs the means and conditions for amending it. Connecticut’s statute adds rules on who must approve an amendment, how an amendment affects a transferee, and what happens when a filed record conflicts with the agreement. Each rule is in Section 34-243f.[1.5]
Our free Connecticut form has 15 pages and is made for an LLC with one member and one or more managers. It has 31 numbered sections and three schedules. The list below shows what the main sections cover, so you can see what the document does before you fill it in.
Our single-member Connecticut form asks for a small set of details. Collect them first, so you can fill in the blanks in one sitting and sign only when the form is complete.
The form is a single-member agreement, so it names one Member and the company they own. A company with several owners needs the multi-member form instead.

These answers come from Connecticut’s LLC statute and cite the section behind each rule. They describe only what the statute provides, not what your own company must do in each case.
Connecticut’s LLC statute provides for an operating agreement that governs the members’ relations, the company’s activities and affairs, and the means and conditions for amending the agreement.[1.2] The statute also limits what an agreement can change, so check that your terms stay inside those limits.[1.1]
Connecticut’s statute has default rules for the matters an operating agreement covers. To the extent the agreement does not provide for a matter, Sections 34-243 to 34-283d govern the matter.[1.3]
Connecticut’s statute covers the single-member case. One person intending to become the initial member may assent to terms that become the operating agreement when the company is formed. The company is bound by the agreement and may enforce it.[1.4]
