Connecticut . Series LLC not available

Connecticut does not authorize Series LLCs. Here is what to do instead.

Connecticut has not statutorily authorized the Series LLC structure. Founders looking for the asset-segregation benefits of a Series LLC have three practical alternatives: standalone LLCs per asset, parent-subsidiary structure, or a Series LLC formed in a state that authorizes them (typically Delaware, Texas, Illinois, or Nevada) with foreign qualification into Connecticut.

Three alternatives for Connecticut founders

1. Standalone LLCs per asset

Form a separate Connecticut LLC for each property or risk pool. Cleanest structure, full asset protection, but higher cost per entity.

2. Parent-subsidiary structure

A holding LLC owns multiple operating subsidiaries. Each subsidiary owns one asset or business line. Common for real estate and multi-brand operations.

3. Series LLC in Delaware + foreign qualification

Form the Series LLC in a state that authorizes them (Delaware, Texas, Illinois, Nevada), then foreign-qualify in Connecticut. Inter-series protection works in the home state; respect by Connecticut courts is uncertain.
