Maine does not authorize Series LLCs. Here is what to do instead.
Maine 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 Maine.
Discuss alternatives →Three alternatives for Maine founders
Form a separate Maine LLC for each property or risk pool. Cleanest structure, full asset protection, but higher cost per entity.
A holding LLC owns multiple operating subsidiaries. Each subsidiary owns one asset or business line. Common for real estate and multi-brand operations.
Form the Series LLC in a state that authorizes them (Delaware, Texas, Illinois, Nevada), then foreign-qualify in Maine. Inter-series protection works in the home state; respect by Maine courts is uncertain.
