(c) A party that objects to the results of genetic testing may call a genetic-testing expert to testify in person or by another method approved by the court. Unless the court orders otherwise, the party offering the testimony bears the expense for the expert testifying.
(d) Admissibility of a report of genetic testing is not affected by whether the testing was performed:
(1) Voluntarily or under an order of the court or a child-support agency; or
(2) Before, on, or after commencement of the proceeding.
74 Del. Laws, c. 136, § 1; 70 Del. Laws, c. 186, § 1; 85 Del. Laws, c. 276, §§ 58, 59;(a) A proceeding to determine whether an alleged genetic parent who is not a presumed parent is a parent of a child may be commenced:
(1) Before the child becomes an adult; or
(2) After the child becomes an adult, but only if the child initiates the proceeding.
(b) This subsection applies in a proceeding described in subsection (a) of this title if the individual who gave birth to the child is the only other individual with a claim to parentage of the child. The court shall adjudicate an alleged genetic parent to be a parent of the child if the alleged genetic parent:
(1) Is identified under § 8-506 of this title as a genetic parent of the child and the identification is not successfully challenged under § 8-506 of this title;
(2) Admits parentage in a pleading, when making an appearance, or during a hearing, the court accepts the admission, and the court determines the alleged genetic parent to be a parent of the child;
(3) Declines to submit to genetic testing ordered by the court or a child-support agency, in which case the court may adjudicate the alleged genetic parent to be a parent of the child even if the alleged genetic parent denies a genetic relationship with the child;
(4) Is in default after service of process and the court determines the alleged genetic parent to be a parent of the child; or
(5) Is neither identified nor excluded as a genetic parent by genetic testing and, based on other evidence, the court determines the alleged genetic parent to be a parent of the child.
(c) Subject to other limitations in this Part, if in a proceeding involving an alleged genetic parent, at least 1 other individual in addition to the individual who gave birth to the child has a claim to parentage of the child, the court shall adjudicate parentage under § 8-613 of this title.
74 Del. Laws, c. 136, § 1; 70 Del. Laws, c. 186, § 1; 77 Del. Laws, c. 456, § 5; 85 Del. Laws, c. 276, §§ 58, 60, 73, 76;(a) A proceeding to determine whether a presumed parent is a parent of a child may be commenced:
(1) Before the child becomes an adult; or
(2) After the child becomes an adult, but only if the child initiates the proceeding.

(2) The child has more than 1 presumed parent.
(c) The following rules apply in a proceeding to adjudicate a presumed parent’s parentage of a child if the individual who gave birth to the child is the only other individual with a claim to parentage of the child:

(2) If the presumed parent is identified under § 8-506 of this title as a genetic parent of the child and that identification is not successfully challenged under § 8-506 of this title, the court shall adjudicate the presumed parent to be a parent of the child.
(3) If the presumed parent is not identified under § 8-506 of this title as a genetic parent of the child and the presumed parent or the individual who gave birth to the child challenges the presumed parent’s parentage of the child, the court shall adjudicate the parentage of the child in the best interest of the child based on the factors under § 8-613(a) and (b) of this title.
(d) Subject to other limitations in this Part, if in a proceeding to adjudicate a presumed parent’s parentage of a child, another individual in addition to the individual who gave birth to the child asserts a claim to parentage of the child, the court shall adjudicate parentage under § 8-613 of this title.
74 Del. Laws, c. 136, § 1; 70 Del. Laws, c. 186, § 1; 77 Del. Laws, c. 456, §§ 2, 7; 85 Del. Laws, c. 276, §§ 58, 61;(a) A proceeding to establish parentage of a child under this section may be commenced only by an individual who:

If the court holds a hearing under this subsection, the hearing must be held on an expedited basis.
(d) In a proceeding to adjudicate parentage of an individual who claims to be a de facto parent of the child, if there is only 1 other individual who is a parent or has a claim to parentage of the child, the court shall adjudicate the individual who claims to be a de facto parent to be a parent of the child if the individual demonstrates by clear-and-convincing evidence that:
(1) The individual resided with the child as a regular member of the child’s household for a significant period;
(2) The individual engaged in consistent caretaking of the child;
(3) The individual undertook full and permanent responsibilities of a parent of the child without expectation of financial compensation;
