A corporation which is incorporated under the laws of a different state or nation. a “foreign” corporation must file a notice of doing business in any state in which it does substantial regular business. it must name an “agent for acceptance of service” in that state, or the secretary of state in some jurisdictions will automatically be that agent so people doing business with a foreign corporation will be able to bring legal actions locally if necessary. example: the whoopee widget corporation is incorporated in delaware. it has a sales office in arizona, which does not make a guaranteed refund to jack jones of arizona. jones can sue whoopee in arizona and serve the arizona secretary of state or whoopee’s designated agent.
