(b) Any act of doing an insurance business as provided by the Insurance Code, Article 1.14-1, §2, by an unauthorized person or insurer signifies the persons's or insurer's agreement that legal process served under this section has the same legal force and validity as personal service of process in this state on that person or insurer or on that person's or insurer's executor, administrator, or personal representative, or, if a corporation, on its successor in interest.

(e) The courts of this state have jurisdiction over any person defined by the Insurance Code, Article 21.49-1, §2(i), who is not resident, domiciled, or authorized to do business in this state and who files a statement with the commissioner under the Insurance Code, Article 21.49-1, and over actions involving any person defined by the Insurance Code, Article 21.49-1, §2(i), arising out of violations of that article. Any person defined by the Insurance Code, Article 21.49-1, §2(i), is considered to have performed acts equivalent to and constituting an appointment of the commissioner by that person to be that person's lawful attorney on whom process in any action, suit, or proceeding arising out of violations of the Insurance Code, Article 21.49-1, may be served. Copies of process shall be served on the commissioner and transmitted by the commissioner by certified or registered mail to that person at that person's last known address. Procedures and fees for service of process are governed by §7.1404 of this title (relating to Service of Process Procedure for Domestic Insurers Approved To Operate under the Insurance Code, Article 1.28, Foreign and Alien Insurance Companies, Risk Retention Groups, Purchasing Groups, Third Party Administrators, Unauthorized Persons or Insurers, Organizations Formed under the Insurance Code, Article 3.71, and Surplus Lines Insurers).
