(1) the date the insured becomes a party to a suit in which the insured seeks to adopt the child; or
(2) the date the adoption becomes final.
(c) Coverage of an adopted child of an insured under this section ends unless the small employer health benefit plan issuer receives notice of the adoption and any required additional premium not later than the 31st day after:
(1) the date the insured becomes a party to a suit in which the insured seeks to adopt the child; or
(2) the date the adoption becomes final.
