Del. Code tit. 18 § 2102
The purpose of §§ 2103 through 2108 (Unauthorized Insurers Process Act) and §§ 2109 through 2111 (Unauthorized Insurers False Advertising Process Act) of this title is to subject certain insurers to the jurisdiction of the Commissioner and the courts of this State in suits and disciplinary proceedings as provided therein, by or on behalf of insureds or beneficiaries under insurance contracts or the Commissioner. The General Assembly declares its concern that many Delaware residents hold insurance policies delivered in this State by unauthorized insurers, other than as to surplus line coverages written pursuant to Chapter 19 of this title, thus presenting to such residents the often insuperable obstacle of resort to distant courts for the assertion of legal rights under their policies, and that such insurers may induce residents to purchase insurance through false advertising sent into this State. In furtherance of such state interest, the General Assembly herein provides a method of substituted service of process upon such insurers, declares that in so doing it exercises its power to protect Delaware residents, to define, for the purposes of this chapter, what constitutes doing business in this State, and also exercises powers and privileges available to the State under 15 U.S.C. § 1011 et seq., as amended, which declares that the business of insurance and every person engaged therein shall be subject to the laws of the several states.
