    See who may act

    A commercial registered agent listed with the Secretary of State, or a noncommercial agent: an individual or entity serving as agent in Maine, or the holder of a named position in the company. The rule comes from 5 M.R.S. § 105.

  3. Assignment

    Pass the address test

    A noncommercial agent lists a physical street address in Maine, not a P.O. box. Commercial agents keep their address on file with the state.

    Every graded service supplies the Maine office address.
