Arizona does not authorize Series LLCs. Here is what to do instead.
Arizona 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 Arizona.
Discuss alternatives →Three alternatives for Arizona founders
Form a separate Arizona 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 Arizona. Inter-series protection works in the home state; respect by Arizona courts is uncertain.
