The first type is a Certificate of Conversion from a domestic entity to a foreign entity. This type of Certificate of Conversion is used when a domestic entity, such as a corporation, wants to convert to a foreign entity, such as an LLC. The second type of Michigan Certificate of Conversion is a Certificate of Conversion from a foreign entity to a domestic entity. This type of Certificate is used when a foreign entity, such as an LLC, wants to convert to a domestic entity, such as a corporation. The Certificate of Conversion must be filed with the Michigan Department of Licensing and Regulatory Affairs.
