What Do South Dakota Registered Agents Do?

At minimum, your South Dakota registered agent accepts legal documents (service of process) and official mail on behalf of your business at a physical address (no P.O. boxes) in the state. This location is called a registered office.

In other words, your registered agent’s address acts as the official place where any service of process and official mail for your South Dakota LLCSouth Dakota corporation or South Dakota nonprofit will be sent.

However, the right registered agent service can do much more. At Northwest, we go above and beyond the minimum to ensure top speed, security, privacy and support.

How Do I Change My South Dakota Registered Agent?

There are two ways to change your registered agent in South Dakota.

  1. Hire us and we’ll complete the change of agent form for you for free.
  2. Do it yourself and file a Statement of Change of Registered Agent form with the South Dakota Secretary of State. There is a $10 fee to file this form.

South Dakota Registered Agent FAQs

Why Do I Need A South Dakota Registered Agent?

South Dakota requires all registered businesses to appoint a registered agent. The secretary of state will reject your business filing if you don’t appoint a registered agent. The registered agent requirement exists so the general public and the have a reliable way to contact your business.

Can I Be My Own Registered Agent In South Dakota?

Yes, you can be your own registered agent in South Dakota. However, after considering the registered agent requirements most business owners elect to hire a registered agent service instead. Why? Well although being your own registered agent will cost you $0, a South Dakota registered agent’s name and address becomes part of the public record.  Additionally, the registered agent is required to be available to accept service of process during normal business hours 5 days a week.

Where Is Northwest’s Registered Office In South Dakota?

Can I Use Your South Dakota Registered Office Address For Everything On My Business Filing?

Please do! We’re the only national registered agent service that allows our clients to list our address for everything when you’re doing a filing to keep your private address off public records.

Can I Have My Business’s Mail Delivered To Your South Dakota Office?

We don’t want ALL of your business mail. It’s not what we do. And it wouldn’t serve you well. You wouldn’t have unique address or suite number. Any mail we receive on your behalf would come to to Northwest Registered Agent, care of you.

But we understand that businesses and clients sometimes reach out to you through your registered agent. Through us. That’s why we give you 5 FREE scans of regular business mail a year. You can request any additional documents to be forwarded at a per document rate of $15.

Do I Hire A Registered Agent Before Or After I Start My Business In South Dakota?

You should hire us first and then form your LLC or corporation because the secretary of state will reject your business registration filing if you don’t. You’ll find all the forms and instructions you need to complete your filing instantly after you place an order.

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:

  • 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.
  • 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.

How Do I Search For A South Dakota Registered Agent?

  • Perform a South Dakota business name search via the SD Secretary of State.
  • Type in the name of the company you’re searching for.
  • Find the registered agent’s name and registered office street address in the search results.

If you want to legally notify a business through their South Dakota registered agent service, just send a letter through certified mail directly to the registered agent at their registered office address.
