From Montana to Connecticut, step by step
Order the Montana certificate
The Certificate of Existence ($5) is ordered from Montana separately; it is not part of our Connecticut order. Connecticut accepts it within 90 days of Montana's issue date, so it is ordered shortly before filing.
We prepare and file the registration
It names us as your Connecticut registered agent, with your Montana name and formation date and the certificate attached. The Montana certificate comes first; then the Connecticut filing goes in. Once Connecticut approves it, the Montana company can do business there.
