Index notes

The deciding column for Maine was coverage per dollar (32% of the index), where Mainstay Filing led.

With the LLC in two states, coverage decided it.

Official Maine foreign LLC registration fee and rules

The Maine Secretary of State, Division of Corporations, UCC and Commissions receives the Statement of Foreign Qualification to Conduct Activities (Form MLLC-12) and $250 from out-of-state LLCs that do business in Maine. Include certificate of existence not older than 90 days.

Ignoring the rule risks its own claims cannot be brought (31 MRSA 1629(1)).
