Indiana Code Title 27. Insurance § 27-1-17-2

Sec. 2. No foreign or alien company shall be admitted for the purpose of transacting any kind or kinds of insurance business in this state, the transaction of which by a domestic company is not permitted by the laws of this state;  provided, however, that where a foreign or alien company whose charter provides for the transaction of the kind or kinds of insurance described in more than one (1) class of IC 27-1-5-1 has been transacting business in this state under a certificate of authority issued by the insurance department or insurance commissioner prior to March 8, 1935, such company may be issued a certificate of authority under the provisions of this article to make the kind or kinds of insurance provided by its charter.  A foreign or alien insurance company admitted to do an insurance business in this state shall have the same but no greater rights and privileges than a domestic company.
