How Connecticut companies register with South Dakota
Order the Connecticut certificate
The Certificate of Legal Existence ($50) is ordered from Connecticut separately; it is not part of our South Dakota order. It comes as a short form ($50) or a long form ($100). South Dakota wants the Connecticut certificate current, so it is ordered close to the filing date.
We prepare and file the registration
It lists us as your South Dakota registered agent, next to your Connecticut name and formation date, with the certificate attached. Once Connecticut's certificate is in hand, South Dakota's filing goes in. After approval, your Connecticut LLC is registered with South Dakota.
