The chapter, section by section

  1. Section 1

    Decide if the LLC must register

    An LLC formed in another state must register with Arizona before conducting business there. An LLC that operates unregistered faces: until registered, the LLC cannot bring suit before Arizona's courts (A.R.S. 29-3902(B)) its contracts can still be enforced (A.R.S. 29-3902(C))

  2. Section 2

    Order the certificate your home state issues

    You will need certificate of existence or good standing, plus a certified copy of the organizational documents, no older than 60 days.

    Ask for it close to the date of filing.

  3. Section 3

    Select the Arizona statutory agent

    Every LLC must name a registered agent with an in-state street address. The address has to be a place of business or residence in Arizona with a street address. A P.O. box can be listed only as a separate Arizona mailing address.
