13 Del. C. § 8-307: Proceeding for rescission [Effective Dec. 6, 2026].

(a) A signatory may rescind an acknowledgment of parentage or denial of parentage by commencing a proceeding to rescind before the earlier of:

(1) Sixty days after the effective date under § 8-304 of this title of the acknowledgment or denial; or

(2) The date of the first hearing before a court in a proceeding, to which the signatory is party, to adjudicate an issue relating to the child, including a proceeding that establishes support.

(b) If an acknowledgment of parentage is rescinded under subsection (a) of this section, an associated denial of parentage is invalid, and the Office of Vital Statistics shall notify the individual who gave birth to the child and the individual who signed a denial of parentage of the child that the acknowledgment has been rescinded. Failure to give the notice required by this subsection does not affect the validity of the rescission.
