A Connecticut Certificate of Formation, also known as a Certificate of Organization, is a document filed with the Secretary of State's office in the state of Connecticut. It is the document that formally creates a limited liability company (LLC). It must include the LLC's name, address, purpose, duration, and other required information. There are several types of Connecticut Certificates of Formation, including LCS, professional LCS, limited partnerships, and limited liability partnerships. All of these documents require the signature of a member or manager of the LLC, and must be filed with the Secretary of State's office. Once approved, the Certificate of Formation serves as the official record of the LLC's existence and is required for the LLC to conduct business in the state of Connecticut.
