(a) Any act of transacting an insurance business as set forth in § 38-25-110 by an unauthorized insurer is equivalent to and constitutes an irrevocable appointment by the insurer, binding upon him, his executor or administrator, or successor in interest if a corporation, of the Secretary of State or his successor in office to be the true and lawful attorney of the insurer upon whom may be served all lawful process in any action, suit, or proceeding in any court by the Director of the Department of Insurance or his designee, or by the State and upon whom may be served any notice, order, pleading, or process in any proceeding before the Department of Insurance and which arises out of transacting an insurance business in this State by the insurer. Any act of transacting an insurance business in this State by an unauthorized insurer is signification of its agreement that any such lawful process in such court action, suit, or proceeding and any such notice, order, pleading, or process in such administrative proceeding before the Department of Insurance so served are of the same legal force and validity as personal service of process in this State upon the insurer.

(b) Service of process in such action is made by delivering to and leaving with the Secretary of State, or some person in apparent charge of his office, two copies thereof and by payment to the Secretary of State of the fee prescribed by law. Service upon the Secretary of State as attorney is service upon the principal.

(c) The Secretary of State shall immediately forward by certified mail one of the copies of the process or the notice, order, pleading, or process in proceedings before the Department of Insurance to the defendant in the court proceeding or to whom the notice, order, pleading, or process in the administrative proceeding is addressed or directed at its last known principal place of business and shall keep a record of all process so served on him which shall show the day and hour of service. The service is sufficient if:

(1) notice of the service and a copy of the court process or the notice, order, pleading, or process in the administrative proceeding are sent within ten days thereafter by certified mail by the plaintiff or the plaintiff’s attorney in the court proceeding or by the Department of Insurance in the administrative proceeding to the defendant in the court proceeding or to whom the notice, order, pleading, or process in the administrative proceeding is addressed or directed at the last known principal place of business of the defendant in the court or administrative proceeding; and

(2) the defendant’s receipt or receipts issued by the post office with which the letter is registered, showing the name of the sender of the letter and the name and address of the person or insurer to whom the letter is addressed, and an affidavit of the plaintiff or the plaintiff’s attorney in a court proceeding or of the Department of Insurance in an administrative proceeding, showing compliance therewith, are filed with the clerk of court in which the action, suit, or proceeding is pending or with the Department of Insurance in administrative proceedings, by the date the defendant in the court or administrative proceeding is required to appear or respond thereto, or within any further time as the court or the Department of Insurance may allow.

(d) No plaintiff is entitled to a judgment by default, a judgment with leave to prove damages, or a judgment pro confesso in any court or administrative proceeding in which court process or notice, order, pleading, or process in proceedings before the Department of Insurance is served under this section until the expiration of thirty days from the date of filing of the affidavit of compliance.

(e) Nothing in this section limits or affects the right to serve any process, notice, order, or demand upon any person or insurer in any other manner permitted by law.
