From Delaware to South Dakota, step by step
Order the Delaware certificate
The Certificate of Good Standing ($50) is ordered from Delaware separately; it is not part of our South Dakota order. It comes as a short form ($50) or a long form ($175). South Dakota wants the Delaware 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 Delaware name and formation date, with the certificate attached. Allow for the days Delaware takes to send the certificate before the South Dakota filing goes in. Once South Dakota approves it, the Delaware company can do business there.
