Indiana Code Title 23. Business and Other Associations § 23-19-6-11

Sec. 11. (a) An irrevocable consent to service of process required by this article must be signed and filed in the form required by a rule or order under this article.  A consent appointing the secretary of state as the person's agent for service of process in an action or proceeding against the person, or the person's successor or personal representative under this article or a rule adopted or order issued under this article after the consent is filed, has the same force and validity as if the service were made personally on the person filing the consent.  A person that has filed a consent complying with this subsection in connection with a previous application for registration or notice filing need not file an additional consent.

(b) If a person, including a nonresident of this state, engages in an act, practice, or course of business prohibited or made actionable by this article or a rule adopted or order issued under this article and the person has not filed a consent to service of process under subsection (a), the act, practice, or course of business constitutes the appointment of the secretary of state as the person's agent for service of process in an action or proceeding against the person or the person's successor or personal representative.

(c) Service under subsection (a) or (b) may be made by providing a copy of the process to the office of the secretary of state, but it is not effective unless:

(d) Service under subsection (c) may be used in a proceeding before the commissioner or by the commissioner in a civil action in which the commissioner is the moving party.

(e) If process is served under subsection (c), the court, or the commissioner in a proceeding before the commissioner, shall order continuances as are necessary or appropriate to afford the defendant or respondent reasonable opportunity to defend.
