South Dakota Amended Articles of Organization are a set of legal documents that must be filed with the South Dakota Secretary of State in order to make changes to an existing limited liability company (LLC). The amended articles allow the LLC to update or amend information such as the company name, registered agent, members, and management structure. There are two types of South Dakota Amended Articles of Organization: articles of amendment and articles of merger. The articles of amendment are used to update information in the LLC’s existing articles of organization, while the articles of merger are used when two or more LCS merge to form a single LLC. Both types of documents must be signed and notarized before filing with the Secretary of State.
