New Hampshire Form C-5 Foreign Limited Liability Company to a NH Limited is a form used to register a foreign limited liability company (LLC) with the New Hampshire Secretary of State. This form must be filed when a foreign LLC is conducting business in New Hampshire or desires to register with the state. There are two types of New Hampshire Form C-5 Foreign Limited Liability Company to a NH Limited: Initial Registration and Amendment. The Initial Registration form is used to file an LLC's original formation documents with the Secretary of State and to establish its presence in the state. The Amendment form is used to make changes to information provided in the Initial Registration form, such as the company's name, address, or members. Both forms must be completed and signed by an authorized officer of the LLC and accompanied by the applicable filing fee.
