A Wyoming Amendment to Certificate is a legal document that is used to make changes to an existing certificate of formation, also known as a Certificate of Incorporation. It is usually used to update the information about the business, such as the company's name, purpose, registered agent, or the number of authorized shares. There are three different types of Wyoming Amendment to Certificates: Articles of Amendment, Restatement of Articles of Incorporation, and Amendment by Merger. All of these documents must be filed with the Wyoming Secretary of State to be legally valid.
