How Maine describes the foreign LLC registration fee and rules

Out-of-state LLCs deliver the Statement of Foreign Qualification to Conduct Activities (Form MLLC-12) to the Maine Secretary of State, Division of Corporations, UCC and Commissions with $250. The filing asks for certificate of existence at most 90 days.

An unregistered LLC can face a lost right to sue in Maine courts (31 MRSA 1629(1)).
