A Wyoming Amended Certificate is a document issued by the Wyoming Secretary of State's office to reflect changes made to a previously filed document. It is used to update information in the original filing, such as changes in a company's name, address, or purpose. There are three types of Wyoming Amended Certificates: a Certificate of Amendment, a Certificate of Merger, and a Certificate of Conversion. A Certificate of Amendment is used to amend, restate, or supplement the original filing. A Certificate of Merger is used when a company merges with another entity. And a Certificate of Conversion is used when a company converts from one type of entity to another.
