How do South Dakota registered agents get served?

Serving a registered agent is legal proof that you were notified. Regardless of whether you receive the documents your South Dakota registered agent signs for on your business’ behalf, once they accept the documents, you’ve been notified. This is a serious responsibility that we do not take lightly. This is how it works:

  1. A process server, the county sheriff, or any third party will walk into our office and hand us the documents (service of process), which we sign for.
  2. The process server then gives an affidavit (a receipt of service) to the court as confirmation that they “served” us.

Note: If you’ve hired us, long before the server hands in their affidavit to the court, you’ve received your documents because we scanned them to your online account within minute of having been served.
