South Dakota Registered Agent Services

You’ll need to designate a South Dakota Registered Agent if your business is formed or operating in the state. The importance of having a trustworthy registered agent for your company cannot be overstressed. A “registered agent” is a person or company that can receive important notices from the state on your company’s behalf and receive Service of Process on your behalf.  Service of Process is broadly defined to include any legal proceeding, legal notice or official government communication presented to the company while it is within the jurisdiction of a state.  If you own a business that operates within the state boundaries of South Dakota, you are required by law to designate a registered agent or physical address where any such service of process can be accepted.  In fact, every state in the country imposes this requirement on all companies, no matter how large or small the business, and whether your company is a limited liability company or a corporation.

A good registered agent ensures that you are promptly notified about any impending deadlines or legal forms that your company must submit to the state. And should you ever find yourself the subject of a lawsuit, having a registered agent ensures that you will be duly notified, so that you can take all the appropriate actions for your company’s legal defense.
