18 Del. C. § 518

(a) A certificate of authority shall continue in force as long as the insurer is entitled thereto under this title, and until suspended or revoked by the Commissioner or terminated at the insurer’s request; subject, however, to continuance of the certificate by the insurer each year by:

(1) Payment on or before March 1 of the continuation fee provided in § 701 (fee schedule) of this title;

(2) Due filing by the insurer of its annual statement for the next preceding calendar year as required by § 526 of this title; and

(3) Payment by the insurer of premium taxes with respect to the preceding calendar year.

(b) If not so continued by the insurer, its certificate of authority shall expire as of midnight on the May 31 next following such failure of the insurer to continue it in force, unless earlier revoked for failure to pay taxes as provided in § 519 of this title. The Commissioner shall promptly notify the insurer of the occurrence of any failure resulting in impending expiration of its certificate of authority.

(c) The Commissioner may, in his or her discretion, upon the insurer’s request made within 3 months after expiration, reinstate a certificate of authority which the insurer has inadvertently permitted to expire after the insurer has fully cured all its failures which resulted in the expiration, and upon payment by the insurer of the fee for reinstatement specified in § 701(1) (fee schedule) of this title. Otherwise the insurer shall be granted another certificate of authority only after filing application therefor and meeting all other requirements as for an original certificate of authority in this State.
