From South Dakota to Connecticut, step by step

Order the South Dakota certificate
The Certificate of Good Standing/Existence ($20) is ordered from South Dakota separately; it is not part of our Connecticut order. Connecticut counts 90 days from the day South Dakota issues it, so the order goes in shortly before filing.
We prepare and file the registration
It lists us as your Connecticut registered agent, next to your South Dakota name and formation date, with the certificate attached. The South Dakota certificate comes first; then the Connecticut filing goes in. Once Connecticut approves it, the South Dakota company can do business there.
