How Maine companies register with Connecticut
Order the Maine certificate
The Certificate of Existence ($30) is ordered from Maine separately; it is not part of our Connecticut order. Connecticut counts 90 days from the day Maine issues it, so the order goes in shortly before filing.
We prepare and file the registration
It names us as your Connecticut registered agent, with your Maine name and formation date and the certificate attached. Once Maine's certificate is in hand, Connecticut's filing goes in. Once Connecticut approves it, the Maine company can do business there.
