The Connecticut LLC Operating Agreement — What Goes In It and Why

An operating agreement is a written contract among the members of an LLC that sets out how the company is owned, run, and governed. It covers who owns what, how money moves, who makes decisions, and what happens when circumstances change. It is an internal document — you keep it in your records rather than filing it with the Connecticut Secretary of the State, and it never becomes public.

Not required, but not optional in practice

Connecticut does not force you to have a written operating agreement. But "not legally required" and "you can skip it" are different things. Without an agreement, the default provisions of the Connecticut Uniform Limited Liability Company Act — Chapter 613a of the General Statutes — fill every gap. Those defaults are one-size-fits-all rules the legislature wrote for LLCs in general; they are not tailored to your business, your members, or your intentions. An operating agreement lets you replace the defaults you do not like with terms you actually chose.

It governs the relationship, not the state paperwork

The Articles of Organization create the LLC in the state's eyes. The operating agreement governs how the people inside it deal with one another. The two do different jobs, and the operating agreement is where the substance of how your business runs actually lives.

A thorough operating agreement addresses the areas where members most often disagree — before there is anything to disagree about. The core sections:

Ownership and capital

• Ownership percentages. Who owns what share of the LLC, expressed as percentages or units.
• Capital contributions. What each member contributed at formation — cash, property, or services — and whether members are obligated to contribute more later.
• Additional contributions. What happens if the company needs more capital: are members required to chip in, and what happens if one cannot or will not?

Profits, losses, and distributions

• Allocation. How profits and losses are divided among members. This often matches ownership percentages but does not have to.
• Distributions. When and how the LLC distributes cash to members, in what order, and who decides.

Management and decision-making

• Management structure. Whether the LLC is member-managed (owners run it) or manager-managed (designated managers run it while some members stay passive).
• Authority. Who can sign contracts, spend money, and bind the company.
• Voting. How votes are counted — weighted by ownership or per member — and which major decisions require a supermajority or unanimous consent.

Changes in membership

• Transfers. Whether and how a member can sell or transfer their interest, including rights of first refusal and approval requirements.
• New members. How additional members are admitted.
• Departure, death, or dispute. What happens when a member wants out, dies, becomes incapacitated, or deadlocks with the others — buyout terms, valuation methods, and exit mechanics.

Dissolution

• Wind-down. The circumstances under which the LLC dissolves and how assets are distributed after debts are settled.

For an LLC with more than one owner, the operating agreement is not a nicety — it is the thing that prevents ordinary business partnerships from ending in expensive disputes.

The problems it heads off

• Profit disputes. Without a written split, arguments about who gets how much are inevitable when real money is on the table.
• Deadlock. When two 50/50 owners disagree and there is no tiebreaker mechanism, the business can freeze. The agreement can build in a resolution path.
• A member wanting out. Absent agreed buyout terms, one member leaving can force a fire-sale valuation or a lawsuit. A pre-agreed method makes exits orderly.
• The unexpected. Death, disability, divorce, or bankruptcy of a member can drag the LLC into situations no one planned for. The agreement decides in advance what happens.

When these situations arise and there is no operating agreement, Chapter 613a's defaults apply — and the members are stuck with whatever the statute says, which frequently is not what any of them would have chosen. Deciding these terms while everyone is on good terms is far easier than fighting over them later.

Owners of single-member LLCs often assume the operating agreement is only for partnerships. It is not.

Reinforcing the liability shield

The whole point of an LLC is separating you from the business. When someone challenges that separation and tries to hold you personally liable — piercing the veil — courts look at whether you treated the LLC as a genuine separate entity. A written operating agreement is evidence of that separation. Skipping it, especially alongside commingled finances, makes the LLC look like an alter ego rather than a real company.

Banks and third parties expect it

Many banks ask for an operating agreement when you open a business account, and investors, lenders, or partners may want to see it. Having one ready avoids delays and looks professional.

Planning for the future

Even a solo owner benefits from writing down succession — what happens to the LLC if you die or become incapacitated. A single-member operating agreement can name what becomes of the company, which spares your family a mess.

An operating agreement is a living document, not a one-time formality that goes in a drawer.

Update it when things change

• A new member joins or a member leaves.
• Ownership percentages shift.
• The management structure changes from member-managed to manager-managed or vice versa.
• Capital contributions or profit splits are renegotiated.

When the reality of the business changes, amend the agreement so it still reflects the truth. An outdated agreement can be worse than none if it says things the members have all silently abandoned.

Keep it consistent with your state record

The operating agreement should not contradict your Articles of Organization. If the Articles say manager-managed and the agreement describes member management, that inconsistency is a problem. Keep the internal document and the state record aligned.

How Mainstay Filing helps

We form your Connecticut LLC and make sure the state-facing paperwork — the Articles of Organization and your registered agent — is done right. The operating agreement is your internal document, and because it is a contract that allocates money and control among owners, its terms are genuinely legal decisions. We are a filing service, not a law firm, so for a multi-member LLC with meaningful stakes we recommend having an attorney help draft or review the agreement. What we ensure is that the formation is solid, so the operating agreement has a properly created LLC to govern.
