Is an operating agreement required for Connecticut LLCs?

This page has not confirmed whether Connecticut law requires an LLC to have an operating agreement, so it does not answer yes or no. A written agreement signed by every member is worth having either way. It records who owns what share of the LLC, who makes decisions, and how profits are divided. To learn what Connecticut requires, check the website of the state agency that registers LLCs in Connecticut, or ask a business attorney licensed in Connecticut.

Can I write my own Connecticut LLC operating agreement?

Yes, you can write your own Connecticut LLC operating agreement. It should cover each member's ownership share, voting rights, how profits are divided and how the LLC is closed down, because the default rules in Connecticut's LLC law can apply where the agreement is silent. Read the guidance for LLCs on the website of the state agency that registers them in Connecticut, and consider having a business attorney licensed in Connecticut review your draft before the members sign it.

Does a Connecticut LLC operating agreement need to be notarized?

This page has not confirmed whether Connecticut law asks for an operating agreement to be notarized. Have every member sign and date it and keep it with the LLC's records. A bank or lender may ask for notarized signatures, so ask before you sign.

Can a Connecticut LLC operating agreement be amended?

Yes. An operating agreement can be changed by following the amendment procedure it sets out, such as a vote or the written consent of the members it names. If the agreement says nothing about amendments, the default rules in Connecticut's LLC law can apply, so check them, or ask a Connecticut business attorney, before you change a term. Put each amendment in writing, have the members sign it, and keep it with the agreement. To amend the LLC's Certificate of Organization on file with the state, Connecticut uses a separate filing, the Certificate of Amendment.

What to Include in Your Operating Agreement

Ownership & membership

Define each member's ownership percentage, capital contributions, and membership interests. This section establishes who owns what portion of the LLC and prevents future disputes about ownership stakes.

Management structure

Specify whether your Connecticut LLC will be member-managed or manager-managed and outline the roles and responsibilities of each position. This clarifies who has authority to make business decisions and bind the company.

Voting rights

Establish voting procedures, quorum requirements, and what decisions require member approval. Where the agreement is silent, the default rules in Connecticut's LLC law can apply.

Profit & loss allocation

Detail how profits and losses will be distributed among members and when distributions will be made. Where the agreement is silent, the default rules in Connecticut's LLC law can apply.

Member duties

Outline each member's responsibilities, fiduciary duties, and any restrictions on competing with the LLC. This section helps prevent conflicts by clearly defining expectations and obligations.

Dissolution process

Specify the events that trigger dissolution and the procedures for winding up the LLC's affairs. Having clear dissolution terms protects all members and ensures an orderly business closure if needed.
