(a) If a person who intends to be a parent of a child conceived by assisted reproduction dies during the period between the transfer of a gamete or embryo and the birth of the child, the person’s death shall not preclude the establishment of the person’s parentage of the child if the person otherwise would be a parent of the child under sections 46b-450 to 46b-553, inclusive.

(b) If a person who consented in a record to assisted reproduction by a person who agreed to give birth to a child dies before a transfer of gametes or embryos, the deceased person is a parent of a child conceived by the assisted reproduction only if:

(1) The person executed a written document that: (A) Specifically set forth that the person’s gametes may be used for posthumous conception of a child, (B) specifically provided the person who agreed to give birth with authority to exercise custody, control and use of the gametes in the event of the person’s death, and (C) was signed and dated by the person and the person who agreed to give birth; and

(2) The embryo is in utero not later than one year after the date of the person’s death.
